It's best to wash dishes. Are dishwashing detergents safe? What is the danger of dishwashing detergents

Many housewives every day, and not just once, have to wash a mountain of dishes. In supermarkets, departments household chemicals, a wide range of tools are presented to help speed up this process. It is generally accepted that they are economical, foam well, quickly dissolve fat, give porcelain, metal and ceramics a shine. Perhaps this explains the popularity of modern detergents.

But if you are not too lazy to read what substances are part of these miracle chemicals, then they will no longer seem so attractive to you. What's the matter? The fact that the composition of the dishware is close to washing powder, with which for some reason no one is in a hurry to scrub the pans. In other words, no kitchen product is complete without phosphates, surfactants, fragrances, preservatives and colorants.

It is doubtful that this "bouquet" is beneficial to the human body.

Why are dish detergents harmful?

Manufacturers promoting their products to the market invite us to close our eyes to health and safety issues and skillfully operate with the main trump cards: efficiency and economy. Thanks to such propaganda, even children know that concentrated products are good because they last for a long time. On the contrary, liquid products run out quickly, but they cost a penny.

We would like to remind you how surfactants and phosphates affect human health:

• First, they help weaken the immune system.
• Secondly, they adversely affect the skin and cause allergic reactions.
• Thirdly, they are one of the causes of diseases of the digestive system.
• Fourthly, the respiratory system also suffers from them.

It is impossible to reduce or neutralize this influence, since in fact chemicals are poorly washed off with water, even running water. To completely clean, for example, a fork, it must be kept under running water for at least 20 seconds. Therefore, the assertion that modern tools save time is without any basis. By the way, they do not contribute to saving resources either: imagine how much water you need to spend to wash at least one set of dishes properly! Owners of counters will have a hard time.

But even if you do not save water and rinse each plate for at least 15 seconds, particles of harmful particles still remain on it. chemical compounds. Subsequently, they enter your body with food and cause all of the above problems.

Scientists have calculated that modern man during the year, willy-nilly, he drinks 500 ml of the dish. People who live in big cities are so accustomed to gas, smog, emissions and dirty tap water that some accidentally swallowed phosphates do not scare them.

Those who care about their health sooner or later begin to wonder: “How to wash dishes without chemicals?”

How to safely wash dishes

For many centuries before the invention of "fast-acting and economical" detergents, people somehow solved the problem dirty dishes and in some cases quite successfully. So what did they use?

mustard powder handles grease easily. Just sprinkle a little mustard on each plate, moisten it with water and wipe it with the resulting gruel. If you need to wash a large amount of dishes, then they should be placed in a basin with warm or hot water, and add 2 tbsp. spoons of powder. Dishes that have spent at least 10 minutes in mustard water are washed without difficulty. If the plates and pans are too greasy, use hotter water and don't skimp on the mustard.

Keep in mind that mustard is not in the best way on the skin: wear gloves when washing dishes.

Baking soda good for removing persistent tea or coffee deposits on the inner walls of cups, jugs, teapots. It degreases the surfaces of metal, porcelain and ceramic objects and cutlery. It dissolves deposits tiles, sink, chrome taps. Soda is also used to whiten teeth, adding it to toothpaste from time to time.

Distinguish between baking soda and soda ash. Nothing can stand against calcined: they clean plumbing and wash clothes with it. But you should still wash the dishes with baking soda. An exception can be made only for pots, basins or pans that need thorough cleaning. They are rubbed with soda ash, and then rinsed very well.

At the same time, one should not forget about gloves: soda ash is an aggressive alkali.

Laundry soap is a universal detergent with antibacterial effect. They do laundry and wash dishes. "Old-fashioned" soap is hypoallergenic: it contains only natural ingredients. It is based on animal and vegetable fats that are safe for humans. Such soap not only removes contaminants from the surface of dishes - it also destroys pathogens of various infections. If someone at home suffers from a seasonal cold or other contagious disease, his dishes should be disinfected with this particular remedy, which, by the way, is washed off with tap water without residue.

There are two main methods for washing dishes with laundry soap:

1. A sponge is lathered with a piece of soap. Dishes are washed with the resulting foam.
2. Soap is rubbed on a grater and poured into a special container. These "sawdust" are subsequently dissolved in the water intended for washing dishes.

furnace ash in the recent past was one of the few detergents available to the villagers. If you have an oven, then there should be no problems with washing dishes: just sprinkle wet plates and pans with ashes, and then wipe them with a rag or washcloth and rinse with water. Ash copes with plaque and fat no worse than soda and other natural remedies. It cleans boilers, cast irons, baking trays and other metal objects.

It is not recommended to use the ash formed after the burning of plastic, polyethylene, fabric and other waste for washing dishes. Only wood ash is suitable for this purpose!

As you can see, our ancestors knew very well how to wash dishes. We can do without chemistry, since there are enough options: in any supermarket they sell laundry soap, baking soda and mustard powder. The owners of village houses can not spend money at all: there will always be ash in the stove.

Can I wash dishes with laundry soap? This question arises not casually, but when there are doubts about cleaning products. The stores offer a wide range of household chemicals, which have proven their effectiveness many times in practice. Should I give up detergents?

Should I use detergents?

1. Cleaning products are actually very difficult to wash off dishes. Particles of chemistry remain, and then enter our body, which can lead to a variety of consequences, but obviously not the best ones. Possible weakening of the immune system, allergic reactions and the occurrence of other diseases. Some even claim that the use of detergents can cause cancer.
2. There are substances called surfactants (surfactants). They are in absolutely any detergent and can lead to:

• infertility.
• increase in blood cholesterol.
• destruction of the immune system.
• algae in sewers.
• water bloom.
• deterioration in water quality.

1. Phosphates are another component of surfactants. They enhance their action. Therefore, in some countries they are banned for use in household chemicals.

Phosphates in detergents are very harmful to the body.

Harmful substances are everywhere, you can’t get away from them, but there are a few tips that will help reduce the amount of harmful chemicals in the body:

1. Read the ingredients carefully. There are safe detergents, however, there are not so many of them, and they will cost much more than ordinary ones.
2. Use of special sponges that can wash out more detergent than regular sponges.
3. The use of harmless substances (soda or mustard powder).
4. Manufacture of detergents. The process is not that complicated, you just need to make sure that phosphates and surfactants do not get into the composition.

Can you wash dishes with baking soda?

Laundry soap is one of the safest substances; it can be used for washing dishes.

In order for such a sink to be effective, and to wash off well from the dishes, everything must be done in warm water. But everything is not as simple as we would like. Several problems may arise.

The problem can be solved quite simply:

1. Get a small bowl for dishes.
2. Fill it with water and add baking soda to it.
3. In this basin, wash dishes with laundry soap.
4. After, rinse the dishes under the tap and leave to dry. Divorces will not remain.

Laundry soap and soda will wash dishes well

Baking soda can also act as a cleaning agent on its own.

As for greasy dishes, on which there are drops of fat. First, they will need to be removed with a napkin, and only then proceed to washing. Why not just increase the amount of detergent? And why once again harm the environment?

If the food sticks strongly to the dishes, then grate laundry soap into it, add soda and pour a little water. Stir, put on fire and wait for boiling. Turn off the fire and wait for it to cool down. After this procedure, the pieces of food will get wet and will be well peeled off.

You must have noticed interest on laundry soap. They indicate the content of fatty acids. Usually this figure is 64, and the maximum allowable according to Russian standards is 72.

Laundry soap that complies with GOST does not cause such severe harm to the environment and humans as ordinary detergents.

Laundry soap - does not cause severe harm to the body

Be careful! There is laundry soap on the market white color. It smells nicer than brown, but it is not used for washing dishes, as its color and smell are the result of bleaching and perfumes. In addition, it contains an artificially synthesized preservative, BHT, which can cause unpleasant consequences after ingestion.

Do not use white laundry soap for washing dishes!

Like everything, laundry soap has its drawbacks.

1. The most significant of them is the high content of insoluble particles, because of this it is necessary to rinse the dishes very well after washing.
2. If you have hard water, then it may not foam well, for this you will have to add soda.
3. Laundry soap can dry out the skin, so after washing the dishes you need to smear your hands with cream. There is another option, add glycerin to the soap (it is sold in a pharmacy, do not confuse it with glycine).

Dishes should be washed thoroughly after washing.

We prepare improved laundry soap with our own hands

You will need:

• a saucepan, which is not very sorry;
• soda;
• glycerol;
• spoon;
• grater;
• ordinary laundry soap (not white);
• molds;
• essential oil of your choice.

Now let's move on to cooking:

1. Grate laundry soap and place it in a saucepan.
2. Add a little water, so that it is 5 times less than the chips (by the way, do not compress them).
3. Place the saucepan over low heat and stir occasionally. Don't leave the stove.
4. As soon as the liquid mass is homogeneous in the pan, add soda and mix until smooth.
5. At the very end, add glycerin (no more than a tablespoon) and essential oil (it acts as a fragrance, only natural).
6. Mix everything and keep a little on fire. As you notice that the mixture begins to run out and become viscous, turn off the heat.
7. Do not wait until the mixture is very viscous and cool too, place it in molds (they must be silicone or special for soap, otherwise do not pull it out later).
8. Once the soap has hardened enough, carefully remove it from the molds and place it on a mat to dry. Drying should take place in a well-ventilated area.
9. Once the soap is completely dry, it can be used.

Now let's explain a little why this is an improved laundry soap. After adding soda, soap should lather better even in hard water. Glycerin performs the same function, but is also a good moisturizer, so the soap will not dry out the skin as much. Essential oils interrupt the unpleasant odors of ordinary laundry soap. Recommended scents:

• orange;
• pines;
• juniper;
• lavender.

Others may be suitable for amateurs, but the above are usually liked by everyone.

So, let's sum up. Laundry soap is perfect for washing dishes, it is much safer than conventional detergents, both for nature and for humans. At first, some inconvenience may arise from the habit, but health is more expensive, so you can quickly get used to it.

What is the best detergent for washing dishes?
Since the dishes have to be washed at least three times a day, and not always with the help of a dishwasher, it is better to understand what and how washes grease from our plates. Moreover, today there are at least three of the most common options for washing dishes with different detergents.

First of all, we should decide what kind of effect we expect from such funds? Let's start with the main thing - with the so-called washing ability. This is an indicator of how effective the remedy is. Such data, as a rule, manufacturers do not indicate on their products, so you can navigate by composition, since the washing ability depends on the set of included components. The main ones are surfactants - surfactants that dissolve dirt, transfer it to a suspended state and allow it to be washed off with a stream of water.

Household chemicals (how to choose dishwasher detergent)
Traditional dish detergents use anionic surfactants. Recently, however, manufacturers have relied on polyalkyl glycosides, which are less toxic in effect, or amphoteric (generally non-toxic) surfactants and their combinations. So if you are not too lazy to read the very small print on the detergent packaging (which, by the way, almost all manufacturers sin if they give information about the composition at all), you yourself can choose the most effective harmless product already in the store.
Another indicator that affects the washing ability is the pH factor - the level of activity of hydrogen ions. The natural pH level for human skin ranges from 5.5, our GOST allows dishwashing detergents to remain in the range from 4 to 11.5. gloves. The most optimal, close to natural pH, are the so-called balms, which today appeared on our shelves in a huge assortment. However, here we must understand: winning in one, we lose in another. In this case, efficiency.
In addition to surfactants, dishwashing detergents include phosphates, peroxide salts, enzymes, natural bactericides and foam stabilizers, diethanolamine (diethanolamine) and chlorine (chlorine). They are the ones that have a detrimental effect on humans.
Adviсe

• Do not drip the product directly onto a plate, but add it to a sponge or water.
• Rinse dishes thoroughly. Synthetic detergent after a short one-time rinse is not washed off its surface. Be sure to rinse the dishes for about 15 seconds in running water.
• Wash dishes with gloves. Any tool, no matter how good it may be, is designed to wash dishes well, and not protect your skin from the toxic effects of chemicals.

Ecological detergents

In order for the dishes to be clean and the human body not to be poisoned, the right way is to use products consisting of organic substances and produced using environmental technologies from natural raw materials. These are new generation products that do not contain phosphates and other harmful components. Liquid detergents are highly concentrated strong agents that quickly break down fat and soften food residues, they form a foam that is easy to rinse off without residue.
These funds usually include:

• organic lemon acid- it is completely biodegradable and dissolves even stubborn limescale. In addition, it adjusts the pH level in liquid soap. Conventional detergents use chemically synthesized citric acid.
• Alcohol (alcohol) - used to regulate viscosity. For technical purposes, alcohol must be denatured. Eco-products use alcohol denatured with substances that are part of detergents ( Castor oil and caustic potassium).
• Sugar Surfactant (sugar tenside) (Alkylpolyglucosides, APG). Alkylpolyglucosides are very gentle to the skin, biochemically decompose without harming the environment. In their production, vegetable, coconut oils, sugar or starch are used.
• Fatty alcohol sulfate - made from coconut oil. Its cleansing power lasts longer than conventional soap.
• The mild formula of aloe vera and coconut oil derivatives does not irritate the skin of the hands, does not contain phosphates. Decomposed by microorganisms.

Advice
Do not mix eco-products and household chemicals, this can provoke all sorts of chemical reactions that are harmful to health. Using eco-products, it is better to have in your arsenal a number of products intended not only for washing dishes, but also for baking sheets, ovens, microwave ovens, silver and nickel-plated products, tiles, etc.

Grandma's "chemistry"
The most popular safe and high-quality detergent is ordinary dry mustard. It copes well with any greasy dishes, has no unpleasant odor, is pleasant to the touch, easy to use and completely safe for health and environment. You can easily find it in any bazaar or supermarket among spices. And it doesn't cost much at all.
The second good assistant when washing dishes and not only is baking soda. It easily copes with plaque and other non-greasy contaminants. Mustard and soda fight pollution no worse than any well-known and expensive detergents. Baking soda neutralizes the acidic taste of water and absorbs odors from the air. It can also be used as a mild non-abrasive cleaner for kitchen surfaces and sinks.
Do not forget about such a simple and affordable cleaning agent as warm soapy water. In many homes, remnants that are already inconvenient to use are thrown away. Or you can do otherwise - collect the remnants of soap in a plastic container from household chemicals. Filling them with hot water, you get a jelly-like detergent for sinks, baths, tiles. Add baking soda to it and you're good to go. good remedy for washing dishes, free from abrasives and harmful chemical substances. It washes well and linoleum, plastic. Added to the solution of soap residue ammonia, you will get an excellent product for washing painted floors, doors, window frames and other colored oil paint surfaces.

Household (washing) soda. Baking soda's chemical neighbor, sodium carbonate, is a stronger alkali, with a pH of around 11. It gives off harmless fumes and is safer than commercial mixes, but gloves must be worn when handling as it is caustic (corrosive). substance).
Laundry soda removes grease, cleans oil, gasoline, and other substances that solvents are usually used to get rid of; wax, lipstick and neutralizes odors, as does baking soda. Do not use it on fiberglass, aluminum or waxed floors unless you want to remove the wax.
Vinegar is one of the most commonly used ingredients in cleaning products made by knowledgeable people on their own. Its main advantage is that it destroys bacteria, mold and viruses. Numerous studies show that 5% vinegar, which is sold in a regular store, kills 99% of bacteria, 82% of mold and 80% of viruses. Therefore, keep a spray bottle of 5% vinegar in the kitchen and use it to spray cutting boards, table surfaces, washcloths, etc. from time to time. It is not necessary to rinse off, you can even leave the surface treated with vinegar overnight. The pungent smell of vinegar will dissipate within a few hours.

Introduction.

My grandmother ran out of dishwashing detergent. I went to the store with her. There was a huge selection of dishwashing detergents. Which one to choose?

This is how the topic came about. my research -"What's the best way to wash dishes?"

I hypothesized : the best dishwashing detergent is one that combines several qualities: it foams well, washes away grease from plates, does not dry the skin of the hands, is washed off the plate itself, inexpensive.

Target my research: explorewhat is the best dishwashing liquid. To achieve this goal, there were tasks :

1. Examine the literature on the research topic.
2. Select research methods.
3. Conduct experiments
4. Draw conclusions.
5. Give advice on the use of detergents.

My research was as follows plan:

1. Survey of adults.

2. Shopping

3 Experimental

4 Analysis of collected material

5 Compiling a memo

Chapter 1. Review of literature and information sources.

There was little literature on the topic of my research.

I read articles on the Internet from the AiF newspaper and an article by Y. Danchenko in the Novoye Delo newspaper No. 12 that modern detergents are harmful to human health, articles on the vsezdorovo website that talk about the use of laundry soap in everyday life.

I also used the materials of the book "Genealogy of things" (article Burovik K.A. "Soap") and the children's encyclopedia "I know the world."

An article by Pyatirikova Zh. “Patience and work will grind everything down” and articles from the Izvestia newspaper helped me find out how people washed dishes in the past.

I re-read some of the works of K. Chukovsky.

How did people wash dishes in the past?

The Indians in the stories of Seton-Thomson gave the dogs to lick the frying pans.

In ancient Korea, in the imperial kitchen, wood ash was dissolved in clay vats and heated to 45 degrees, then dishes were washed in it, rinsed in three boiled waters, adding lemongrass solution, coniferous solution. At the end, they simply rinsed in boiled water. Labor-intensive, but retained the exceptional taste of the products. [ 6 ]

The oldest villagers remember those times when the dishes were rubbed with brick chips. Even earlier, the dishes were washed with a solution of ash. Soda was good at scrubbing tea and other stains on cups and plates, soot on pots. Another folk remedy- nettle, which was instead of a washcloth. After it, it remained to douse the dishes with boiling water, and it shone like new. People who lived near water bodies used algae to wash dishes. Fat from dishes was easily removed with hemp leaves, a solution of mustard powder, hot potato broth. The pots boiled well with the addition paper glue and soda ash. Pots become like new again, only after boiling they should be washed well. [5] Remembering Chukovsky's "Fedorino's grief", we learn that it is good to wash dishes with the help of river sand.

“Oh you, my poor orphans,

Irons and frying pans are mine!

You go home, unwashed,

I will wash you with water.

I will sand you

I will douse you with boiling water ... "[ 8 ]

Many grandmothers washed and now wash dishes using laundry soap. It is good at killing germs.

Where did soap come from?

History of soap.

Historians claim that the predecessor of modern soap was familiar to the ancient Babylonians. Clay tablets found in Mesopotamia dating back to 2200 B.C. , contain detailed description technological process soap making. Ancient Rome, Egypt knew effective recipes detergents. The word soap comes from the Latin "sapo", the name of Mount Sapo in ancient Rome, on which the ritual of sacrifice to the gods took place. Animal fat, which accumulated after the burning of the victim, was mixed with the ashes of the fire, washed off into the Tiber River. Housewives, washing clothes in this water, noticed that the washing process was much easier, things became clean much faster. However, a bar of soap received its modern composition only in 1808, thanks to the French chemist Michel Eugene Chevreul. It was he who developed the soap formula at the request of the owners of the textile factory. Soap turned out to be nothing more than sodium salt. carboxylic acid. Laundry soap is one of the types of detergents. It is obtained in the process of cooling soap glue. Animal and vegetable fats are used as raw materials for making soap, which is important for its use: such a product does not cause allergies, being environmentally friendly. , [ 2 ] .

Modern housewives most often use dishwashing detergents, because. it is believed that they are better at washing off fat from dishes, do not dry the skin of the hands, they are more convenient to use. Is it so?

Many women buy products with additives, taking care of the skin of their hands.

Unfortunately, scientists have found that the balm is easily washed off with water, without leaving on the hands and, moreover, without being absorbed into the skin. Glycerin, on the other hand, instantly dissolves in water, without even getting on your hands. [ 3 ]

Conclusion: “emollient” additives do not benefit the skin of the hands. In any case, you should wear gloves when washing dishes, since all detergents dry out the skin.

How the product itself is washed off the plates.

Experts say that the substances contained in dishwashing detergents are very harmful, because. detergents are listed as household chemicals. Dish detergents have approximately the same washability. And you can't test it at home. In addition, laboratory studies show that it will not be possible to completely wash off surfactants from plates - microscopic doses will still remain.

Once in the human body, they are destroyed, which leads to various diseases: gastritis, ulcers, allergies and others. How do these substances enter our body? When rinsing the foam from the detergent, we do not wash off all the detergent to the end. Despite the fact that we washed the foam itself clean. And the remnants of this remedy already with the next meal enters our stomach. To completely wash off the detergent from the plates, scientists advise rinsing the dishes 70 times. Since this is very difficult to do, for simplicity, you need to at least wipe the dishes with a towel. [3], [4].

Conclusion: all detergents are very poorly washed off with water.

What happens. Are we harming our body when using detergents?

Chapter 2 Materials and research methods.

Detergents: soda, laundry soap, Cinderella detergent ( 19 rubles 70 kopecks), means "AOS" (49 rubles 20 kopecks).

Research methods: experience, questioning, photographic fixation (a CANON camera was used for photographing), work with literary sources.

Equipment: petri dishes, reagents, phenolphthalein.

Chapter 3 Results of the survey and their discussion.

3.1 Questioning.

Employees of school No. 5 in Slobodsky participated in the survey. 9 people answered the question "How do you choose dishwashing detergent?"

Answers:

1. Cheap and cleans well. (1 person).
2. It lathers well and does not irritate the skin (2 people).
3. Cheap (3 people).
4. Rinses off dishes quickly and does not irritate hands (1 person).
5. Washes grease off plates (2 people).

(Annex 1).

3.2 Experiments to determine the best detergent.

3.2.1. Experience " The best remedy whatever is cheaper."

Target . Find out which detergent is more economical.

Location: school canteen.

Main part.

First, 1/3 can of cheap detergent was poured into the dishwashing tank. After washing the dishes, the kitchen worker told me that all the dishes were washed well.

The next day, at the same break, I poured a more expensive product into the tank, but 1/6 of a can. The kitchen worker said that this remedy is better, because. it could be used on large quantity plates.

Conclusion.

It turns out that a more expensive product is more economical, it will be enough for more dishes. This means that the one who buys a cheap product even loses money.

3.2.2. Experience "Using a product that washes away fat in cold water».

Target. Find out which detergent is best for removing grease in cold water.

Main part .

Poured on a spoon sunflower oil into the bowls. The first plate was washed with Cinderella, the second with AOS. Both plates were washed in cold water.

It turns out that the main component of all detergents is a complex of "surfactants" (surfactants). These substances interact with the fat on the surface of the dishes. They form compounds with fat particles that are easily washed off with water, leaving no residue on the surface.

Conclusion: any detergent easily washes away grease in cold water.

3.2.3. Experience "It is better to wash dishes with a product that foams."

Target. To know, Which product lathers better?

Main part.

I poured 100 grams of water into two identical saucers. On two identical sponges, a drop of the product was applied. Foam from "AOS" was 3 times more.

(Appendix 2).

But scientists believe that it is not necessary to evaluate the foaming ability of detergents, since the surfactant washes everything off perfectly without the formation of abundant foam - this property is used in powders for washing machines.

Conclusion: foam does not affect the quality of washing dishes.

3.2.4. Experience "How laundry soap washes away grease from plates."

Target. Find out if laundry soap washes grease off the plate.

Main part

Dropped on a plate vegetable oil. The sponge was soaked in water and lathered with laundry soap. I washed the plate in cold water with a sponge. There was no fat left on the plate.

Conclusion: Laundry soap washes away grease from plates.

3.2.5.Experiment "Laundry soap is washed off the plates."

Target. Check if the laundry soap is washed off the plates.

Main part.

Phenolphthalein was dropped onto a plate with foam from laundry soap (phenolphthalein changes color depending on the pH level of the medium. Thisacid-base indicator that changes color from colorless to red-violet, "crimson" (in alkaline), the foam turned pink. This plate was rinsed in cold running water. Again dripped phenolphthalein, the color has not changed. (Appendix 3).

Conclusion: Laundry soap is completely washed off with water.

Laundry soap costs 16 rubles, it's cheap. It washes away fat from plates, it is quickly washed off the plate itself. Disadvantage: dries the skin of the hands.

conclusions

1. Experiments carried out

It is best to wash dishes with laundry soap. It is economical, safe, high quality. Dishes washed with a bar of soap shine with cleanliness, no streaks or films. And, if someone is used to using liquid detergents, then he will be interested in the recipe that I found on the Internet.

For the manufacture of liquid you need: 25 grams of laundry soap, 0.5 l hot water, 4 tablespoons of glycerin, 1 tablespoon of vodka.

Cooking method: grate soap, pour soap shavings with a small amount of hot water and set to melt in a water bath (or microwave). While stirring, gradually pour out all the water. After the soap is completely dissolved, let it cool a little and add glycerin and vodka, mix everything thoroughly. We collect the foam that appeared as a result of mixing from the surface.

The result was a liquid mass without unnecessary chemical additives. It is very convenient to wash dishes. But it takes time to make liquid. [ 7 ]

And you can put small pieces (remnants) of laundry soap into a bottle and pour hot water. After a few hours, thick dishwashing liquid is ready (my grandmother does).

I also decided to make a memo for everyone who washes dishes. (Appendix 4).

memo

So that in the pursuit of clean dishes you do not have to pay with your health and the health of your loved ones, follow a few rules:

1 Wash dishes only with gloves

2 Use laundry soap and soda when washing dishes.

If you are using detergent:

1) first drip the product onto a sponge or into water, but not onto the dishes themselves (this makes it easier to wash off).

2) Rinse each plate under running water for as long as possible.

3) wipe the dishes with a towel (this way you can remove up to 90% of surfactants).

4) Keep detergent bottles closed to prevent toxic fumes. Enough of the fact that you breathe them while washing dishes.

I started my research with a survey. I asked the employees of School No. 5: “How do you choose your dishwashing liquid?” The answers were different.

I studied the literature and information sources on this topic and found out:

1. "Emollient" additives do not bringbenefits for the skin of the hands. Unfortunately, scientists have found that the balm is easily washed off with water, without leaving on the hands and, moreover, without being absorbed into the skin. Glycerin, on the other hand, instantly dissolves in water, without even getting on your hands. In any case, you should wear gloves when washing dishes, since all detergents dry out the skin.
2. All detergents are very poorly washed off with water. Experts say that the substances contained in dishwashing detergents are very harmful, because. detergents are listed as household chemicals. Once in the human body, they are destroyed, which leads to various diseases. How do these substances enter our body? We do not wash off all the detergent to the end .. To completely wash off the detergent from the plates, scientists advise rinsing the dishes 70 times. Since this is very difficult to do, for simplicity, you need to at least wipe the dishes with a towel.

5 experiments were carried out. Thanks to them, I came to the following conclusions:

1. A more expensive detergent is more economical, it will last for more dishes. This means that the one who buys a cheap product even loses money.
2. Any detergent can easily wash off grease in cold water.
3. Foam does not affect the quality of washing dishes.
4. Laundry soap removes grease from dishes
5. Laundry soap is completely washed off with water.

Conclusions.

1. Studied 8 literary sources on the research topic.
2. Research methods have been selected.
3. Experiments carried out to clarify the similarities and differences on the example of some dishwashing detergents.
4. Based on the results of each experiment, conclusions are drawn.
5. Compiled a memo with recommendations for the use of detergents for washing dishes.
