Where is soap used? The benefits of laundry soap. Unusual application. Application of liquid soap

14.07.2020

Recently, the trends of the modern beauty industry gravitate towards naturalness and the revival of good old traditions. In particular, more and more often one can hear the opinion that laundry soap for the face is a real salvation from such serious problems as acne, wrinkles and fat content. They are usually the most difficult to deal with, and, judging by the reviews, this unique product can, if used correctly, get rid of these misfortunes. How dangerous is it and is it worth listening to such advice?

Chemical composition

Why does regular washing of the face with laundry soap lead to the elimination of acne, oily sheen, and cleansing of pores? The answer to this question must be sought in its chemical composition.

Animal fats

Animal fats are used in the production of this soap. They provide skin cells with normal functioning. They form a strong film on the surface of the face, which has protective properties (reflects attacks in the form of ultraviolet radiation). They are a real salvation for dry, damaged, thinned skin.

But for oily skin types, they are not very useful, as they can clog pores with sebaceous plugs even more and provoke the appearance of an unhealthy shine on the face.

Sodium

Granular sodium is a caustic and alkaline chemical element. It has undoubted harm on the skin, destroying the structure of cells. It can become dull, gray, thin. But do not panic and immediately refuse to use soap: this effect is observed only with its constant use in large quantities.

Water

Water is an essential ingredient. It effectively moisturizes and is a neutralizer of harmful components (the same, alkalis) in the composition of this product. Minimizes their aggressive action.

Kaolin

Unlike the old, Soviet soap, kaolin is added to modern household soap, which softens the action of alkalis. This is white (porcelain) clay, which repairs damage, promotes rapid tissue regeneration, moisturizes, and controls the amount of secretions from the sebaceous glands. Its useful cosmetic properties can be listed endlessly. At the same time, remember that this substance is not present in all varieties of the product.

Fatty acid

Fatty acids are excellent antioxidants with pronounced regenerating properties. They contribute to the rapid healing of wounds. They are also responsible for cell renewal, which as a result leads to rejuvenation and smoothing of wrinkles.

alkalis

But alkaline compounds destroy the structure of cells, and it is because of them that an avalanche of criticism falls on laundry soap as a cosmetic product. But in order to dry out and spoil the skin of the face, you need a lot of alkali. And here their share is the minimum number. It is much better to see the benefit in them: they expand the pores, opening the way for nutrients (fatty acids, kaolin, etc.), performing a transport function.

The harmful effects of alkalis can be neutralized if, after using the household soap, you rinse with an infusion of herbs that acts in the opposite direction - to close the pores and restore damaged cell structures.

A very important point, which often becomes a significant disadvantage of laundry soap. Because of it, the skin of the face after washing and masks can become very dry, microcracks may appear and even form - this is a high pH level. This indicator should be within 7 (this is the maximum). The best numbers: pH = 5 or 6. And in household soap, it sometimes reaches critical levels of 11 and even 12.

Each ingredient performs a number of functions. Together, they all have a complex antibacterial and disinfectant effect. This leads to the results that many admire when using this product for washing regularly.

through the pages of history. It turns out that laundry soap is French in its true origin. It was first produced in the Middle Ages in Marseille. True, its main ingredient at that time was olive oil: Louis XIV forbade the use of animal fats in its composition.

Beneficial features

Due to the chemical composition, the benefits of laundry soap are undeniable with regular and proper use:

relieves, because it disinfects, stopping the spread of inflammation;
helps with wrinkles, provided they are not too deep;
lightens stretch marks, scars and scars;
is an effective peeling agent for facial cleansing, as it opens the pores and extracts all organic dirt from them;
heals any damage to the skin;
used for oily skin to eliminate ;
moisturizes;
used for age spots.

Do not doubt the effectiveness of this soap - see for yourself by learning how to use it as a cosmetic product.

Medicinal properties. In folk medicine, it is used as an external medicine for swelling, wounds, cuts, abscesses, dandruff, runny nose, fungal infections, bruises, bruises, corns, burns, and even ... gynecological diseases (for example, thrush).

Possible harm

When deciding on the use of laundry soap for facial care, evaluate the possible harm that it can have on the skin. It manifests itself in two cases: if you do not take into account contraindications and if you get carried away with them too much.

Contraindications

Do not use this product if you have the following problems:

dry, dehydrated, dehydrated skin;
very sensitive, thin skin;
propensity to allergies;
rosacea;
serious dermatological diseases (consultation with a specialist is required).

Using it without taking into account these contraindications can worsen the condition of already painful skin.

Side effects

Regular use of laundry soap does not mean that you need to wash your face with it 3-4 times daily. Each skin type has its own recommendations regarding the frequency of its use.

Abuse of this product can lead to sad consequences, among which the most common are:

dehydration;
numerous peelings;
cracks;
suppuration of inflammation and rashes;
irritation;
an allergic reaction in the form of a rash and itching;
couperous mesh;
exacerbation of dermatological diseases.

To avoid such unpleasant surprises, listen to the advice of experts and do not ignore contraindications.

This is interesting! Military doctors and employees of the Ministry of Emergency Situations know that laundry soap can replace surgical gloves in emergency situations. They just wash their hands and leave to dry.

Application features

The usefulness of the product is largely determined by the literacy of use. Using it like a regular cosmetic soap is wrong and leads to unpleasant side effects. Therefore, try to adhere to the following simple rules.

The procedure is best done an hour before bedtime, during the evening.
Moisturize a pre-cleansed face.
Lather your palms liberally to create lather.
Gently rub them over your face, avoiding the area around the eyes and lips.
Wash off with plenty of water.
You do not need to wipe yourself, so that the water softens the aggressive action of alkalis and sodium.
After 20 minutes, apply a nourishing or moisturizing cream.
If the problem is local (a couple of pimples or a pigment spot), the foam is applied pointwise to this area for 5-7 minutes, and then removed with a damp cotton pad.
It is recommended to wash your face a couple of times a week, as more frequent use will be addictive, and the sebaceous glands will begin to produce a secret twice as much.
After a couple of months, you need to take a break for 3-4 weeks.
If irritation occurs after the procedure, it is no longer recommended to repeat it.

The effectiveness of laundry soap will be partly determined by the manufacturer and variety, so you still need to be able to choose it.

1. History of soap.

The debate about who humanity owes the invention of soap has not yet been completed, however, the honor of saving humanity from dirt is attributed to several ancient peoples at once.

Soap has been reported to have been made as far back as ancient Sumer and Babylon around 2800 BC. BC. Descriptions of soap making technology have been found in Mesopotamia on clay tablets dating back to around 2200 BC. Egyptian archaeologists, after excavations in the Nile Delta, came to the conclusion that the production of soap was established at least 6,000 years ago. Egyptian papyrus from the middle of the second millennium BC. testifies that the Egyptians regularly bathed with soap.

The Roman scholar and politician Pliny the Elder claims that even the ancient Gauls (who inhabited the territory of modern France) and the Germans knew about the preparation of soap. According to him, these wild tribes made some kind of miraculous ointment from the tallow and ashes of the beech tree, which was used to clean and dye their hair, as well as to treat skin diseases.

There is also a version that soap was made by the Romans. Legend has it that the very word soap (soap) comes from the name of Mount Sapo in ancient Rome, where sacrifices were made to the gods. A mixture of melted animal fat and wood ash from a sacrificial fire was washed away by rain into the clay soil of the banks of the Tiber River. Women who washed clothes there noticed that thanks to this mixture, clothes were washed much better. People gradually began to use the "gift of the gods" not only for washing clothes, but also for washing the body. By the way, the first soap factories were also discovered by archaeologists on the territory of Ancient Rome, or more precisely, among the ruins of the famous Pompeii.

From the Roman word sapo later the English formed soap, the French - savon, the Italians - sapone.

Soap did not immediately become a hygiene item. Until the 13th century, it stood on a par with medical supplies and medicines. There was no purity in honor even in the Middle Ages. Soap was used only by representatives of the first two classes - nobles and priests, and even then not all of them. Finally, the fashion for purity was instilled in medieval Europe by knights who visited Arab countries during the Crusades. Probably Arabs in the 7th century. AD learned how to make solid soap. From the Arabs, the art of soap making penetrated into Spain. Here they learned how to make solid beautiful soap from olive oil and the ashes of sea plants. Everywhere in the Mediterranean, where oil plants were grown, soap making began to flourish.

From the 13th century Soap making flourishes in France and England. The attitude to this craft was the most serious. In 1399 in England, King Henry IV founded an order whose special privilege was: washing in a bath with soap.

It is known that in the XV and XVI centuries. knights and merchants brought smelling balls from Venice. They were embossed with lilies, fir cones, crescents - the first, if I may say so, trademarks.

In Rus', the secrets of making soap were inherited from Byzantium, and our own master soap makers appeared with us only in the 15th century. It is known that a certain Gavrila Ondreev started in Tver "a soap kitchen with a soap cauldron and all the order", and in Moscow there was even a soap row. The industrial production of soap was established under Peter I, but until the middle of the 19th century. they were only used to know. The peasants also washed and washed with lye - a mixture obtained from wood ash, poured with boiling water and steamed in an oven. The city of Shuya was the main center of soap making, and even a bar of soap is depicted on its coat of arms.

2. What is soap?

As early as 1808, the French chemist Michel Eugene Chevreul (1786 - 1889) established the composition of soap. As a result of the analysis, it turned out that soap is a sodium salt of a higher fatty carboxylic acid. Moreover, liquid and solid soap differ only in cations: one of the options for solid soap is C 17 H 35 COONa, liquid - C 17 H 35 COOK.

3. Obtaining soap.

The production of soap has always been based on the saponification reaction - the hydrolysis of esters of higher carboxylic acids and glycerol (i.e. fats) with alkalis, as a result of which the trihydric alcohol glycerol and salts of higher carboxylic acids (soap) are formed. The reaction equation looks like this:

Picture 1

Soap is made by boiling fatty oils in water with alkalis such as caustic soda or caustic potash. Fatty oils are extracted from plant products such as cottonseed, palm and soybean oils, animal products such as lard and fish oils, and nut products such as coconut oil. Purified fats undergo hydrolysis in the presence of alkalis under a pressure of 5 MPa and at a temperature of 240-260 degrees. This produces soap, fatty acids and glycerin. Glycerol is withdrawn from the reactor, and the remaining mixture is treated with an excess of alkali. Pure soap from the soap-making cauldron is poured into the mixer, where fragrances, dyes and other components are introduced into it. Then it is poured into molds containing 410 kg of soap, and left in them for several days to cool and harden. The side walls of the forms are removed, the mass is trimmed, cut into bars, which are dried and stamped into separate pieces placed in the package. Sometimes soap is subjected to additional processing to improve the presentation (for example, marbling).

4. The mechanism of the washing action of soap.

Soap has been known for thousands of years, but it is only relatively recently that chemists have understood why it has detergent properties. Soap consists of two parts: hydrophobic (organic radical) and hydrophilic (water soluble). For the washing action, it is important that the hydrocarbon part of the negative ion is insoluble in water, but it is soluble in fats and oils, and it is thanks to fat that dirt sticks to things; and if the surface is completely free of grease, dirt does not linger on it. As shown in the figure, the negative ions (anions) of soap tend to concentrate at the interface between water and fat. The water soluble negative end remains in the water while the hydrocarbon portion is immersed in the fat. In order for the interface to be the largest, the fat must be present in the form of tiny droplets. As a result, an emulsion is formed - a suspension of droplets of fat (oil) in water.

Figure 2

If there is a film of fat on a solid surface, then upon contact with water containing soap, the fat leaves the surface and passes into the water in the form of tiny droplets. Soap anions are in water at one end and in fat at the other. Dirt held by a film of grease is removed by rinsing.

Soap has a serious drawback - it loses its soaping effect in hard water. Let's do an experiment. Let's take two glasses. In one, the water is soft, not containing salts of magnesium and calcium, and in the other, it is hard. Pour the soap solution into both glasses. In one of them (with soft water), complete dissolution is observed, with vigorous stirring - foaming of the solution, and in a glass of hard water, we observe the precipitation of a flocculent precipitate. With vigorous stirring, it becomes noticeable that the soap has lost its soaping effect. This is due to the fact that in hard water, soap forms calcium and magnesium salts of higher carboxylic acids, which are insoluble:

2С 17 H 35 COONa + Ca 2+ = (C 17 H 35 COO) 2 Ca + 2Na +

If, after washing with soap, the fabric is rinsed in hard water, an insoluble and difficult-to-remove “calcium soap” is deposited on it, which spoils its appearance. Therefore, in areas with hard water, laundries have to install water softening equipment.

5. Soap bubbles.

Soap has an interesting property - it can create soap bubbles. A soap bubble is a thin film of soapy water that forms a sphere with an iridescent surface. It only exists for a few seconds. The bubble film consists of a thin layer of water sandwiched between two layers of soap molecules. The hydrophilic part is attracted by the thin layer of water, while the hydrophobic part is pushed out. As a result, layers are formed that protect water from rapid evaporation and reduce surface tension.

Back in the 19th century, the Russian chemist G.S. Petrov, by the action of sulfuric acid on oil refining products, obtained synthetic detergents that lather well in hard water. For example, a detergent solution lathers well in both soft and hard water. Let's check it out experimentally. To do this, pour the SMS solution into glasses with soft and hard water. As we can see, with vigorous stirring, foam is formed in both glasses. But the main disadvantage of SMS is the ability to accumulate in the environment, because. sulfonic acids, unlike carboxylic acids, are not processed by microorganisms and accumulate in water bodies, which leads to the death of aquatic flora and fauna. And the phosphates added to these detergents provoke the rapid growth of aquatic vegetation, which leads to eutrophication (aging and swamping) of reservoirs.

6. Soap in nature.

Soap can also be found in nature. Many plants have a cleansing effect. This is soapwort (Saponaria), and common tar (Silene vulgaris), and naked hernia (Caryophyllaceae), and licorice (Glycyrrhiza glabra), and black elderberry (Sambucus nigra) and many others. When rubbing the roots of soapwort, a lush, long-lasting foam is formed. The same foam is formed using licorice root powder. And elderberries, although they do not form foam, perfectly wash the dirt.

7. Prospects for the use of soap.

Regardless of age, soap is in no hurry to lose ground. Today, soap has therapeutic purposes: it is used to treat acne, relieve tension, as an aromatherapy product, and to combat skin aging. Experts believe that the future belongs to soap with aesthetic qualities, when color, shape, aroma become the most important criteria for choosing products. But still, the main function of soap remains hygienic.

Soap is one of the most common items intended for everyday hygiene, but few people know how useful soap is and what is the harm of soap.

There can be benefits and harms to the human body from the use of soap, it all depends on what type of soap is used and for what purposes. Do not use ordinary toilet soap to care for the skin of the intimate area, as this can cause dryness of the skin due to an imbalance in the acid-base balance.

There are different types of soap, some types of this hygiene product are more useful, others are less useful. Soaps are the most commonly used detergents.

If the rules for using this hygiene product are violated, it can cause damage to human skin.

Today, manufacturers offer consumers the following types of this cosmetic product:

toilet;
antibacterial;
soap with the addition of tar;
soap for household needs;
soap for the care of the intimate area of the body;
soap in a liquid consistency;
handmade soap.

Each of these types of detergents has a number of inherent advantages and disadvantages.

For example, antibacterial soap in the process of washing the skin kills most types of unwanted microorganisms, qualitatively cleansing the skin of impurities, soap for the care of the intimate area is designed to cleanse the skin of a person's intimate area and maintain an optimal pH in it. Ordinary toilet soap is designed to be able to wash the body of dirt with high quality.

Benefits of using soap

The main benefit of soap lies primarily in the ability to clean the surface of the skin from impurities.

Modern cosmetic cleansers are not able to clean the skin of the body as well as the most ordinary soap does.

The high cleansing properties of soap are provided by the peculiar composition of the cosmetic product.

The properties of soap depend on the presence of various additives in it. Useful soap contains additives in its composition that improve its certain qualities, the most common are the following:

glycerin - provides moisture to the skin;
honey additives make it possible to give the skin velvety and tenderness;
fir extract helps to accelerate the regeneration of epidermal cells, and accelerates the healing of microtraumas, in addition, fir extract prevents the appearance of acne;
chamomile extract has a calming effect and does not allow the skin to dry;
extracts obtained from St. John's wort, pine and eucalyptus have antiseptic properties.

In addition to these additives, soap may contain a large number of other components.

The benefits of soap with the addition of plant extracts will be really noticeable if all components of natural origin are used in the production process of the product.

Most varieties of solid soap in their composition necessarily contain the following components:

Salts of a mixture of higher fatty acids, most often such acids are lauric, oleic, stearic and palmitic.
Glycerol.
A mixture of flavors or their individual types.
Dyes.

Solid soap is produced as a result of the soap making process, which is a reaction of saponification of oils and fats with sodium hydroxide.

A distinctive feature of solid soap is the presence of an alkaline reaction. This reaction is due to the presence of alkali residues in the composition of the detergent.

Laundry soap at the present stage of development of cosmetology and technology for the production of body care products is undeservedly forgotten. This soap has a whole range of useful properties.

Benefits of using laundry soap

Laundry soap has high cleaning and disinfecting properties. According to surgeons, this soap cleans hands so well that after the procedure, in some cases, you can work without wearing gloves. Moreover, even if microtraumas are formed, then the chances of getting an infection are very minimal.

The use of a household variety of soap allows you to remove irritation on the skin after the epilation procedure. For this purpose, you will need to lather the treated area of \u200b\u200bthe skin, hold it soaped for several minutes and then rinse with plenty of running water.

This type of product can be used to clean and disinfect a toothbrush. To do this, you need to lather the bristles of the brush and then rinse it well, washing off the remnants of the cosmetic product.

Laundry soap can be used as a medicine in case of a runny nose. For this purpose, the nose should be washed with an aqueous solution of soap. Coniferous soap gives a greater effect in the treatment of the common cold. It is made using pine needle extract.

Runny nose ends after two or three procedures.

The use of this type of detergent allows you to get rid of cracked heels and corns. For this purpose, special baths are being prepared. And the time for taking the procedure is 15 minutes for each leg.

In the event of a bruise, laundry soap will help get rid of swelling and bruising. For this purpose, you should rub the place of impact with a hygiene product.

Using laundry soap when washing your hair will prevent hair loss.

Harm from using soap

Frequent use of solid soaps can cause damage to the skin. Soap damage to the skin comes from sodium hydroxide residues remaining after the soap making process.

The alkali, which is part of the soap, provokes the appearance of dryness of the skin and its peeling. This process can be exacerbated when using water with a high degree of hardness.

To reduce the negative impact on the skin, you should stop using cheap soaps containing a large amount of residual alkali.

Soap when used for oily skin is not capable of causing harm, but if you have dry skin, it is recommended to refuse to use solid soap for hygiene purposes.

Do not use soap to clean your face. This is due to the fact that the skin on the face is very delicate and hard soap, having an alkaline reaction, can easily upset the acid-base balance of the skin of the face.

An exception is natural pine soap, which does not contain artificial components in its composition and therefore is not capable of damaging the skin of the face.

Also, to clean the face, you can use liquid coniferous soap, which has a gentle composition and is not capable of damaging the skin of the body.

In order to prevent overdose when using soap, a special dispenser is installed on bottles with liquid soap.

Soap according to its purpose, it is divided into household, toilet, children's, medical and special. For sale soap comes in solid, liquid and powder form. Also released soap in the form of a solution in alcohol (soap alcohol). In addition, soap flakes are used to wash woolen and silk items.

Soap they are produced from animal fats, vegetable oils and their substitutes - rosin extracted from coniferous trees, naphthenic acids obtained from oil refining products (soap oil). Soap with a large number of substitutes is not very suitable for washing woolen and silk fabrics, as it contributes to felting of wool and shrinkage of fabrics. Therefore, for washing wool and silk, better grades of soap should be used.

For the manufacture of soap fats and their substitutes are boiled with a certain amount of caustic soda, which decomposes fats into its constituent parts - fatty acids and glycerin. Acids combine with caustic soda to form soap. The more fatty acids in the soap, the higher its quality. According to their content soap divided into 40 percent, 60 percent, 72 percent, etc. When dry soap the percentage of fatty acids in the soap increases as some of the water evaporates. For household purposes, usually 40 and 60 percent soap is used.

dressing soap contains up to 75% fatty acids. Coloring and smell give it the addition of dyes and fragrances.

In addition to toilet, they produce a special variety soap under the name of a child. It has no color or fragrance. For hygienic purposes, lanolin (1-2%) and boric acid (no more than 0.5%) are added to it.

By adding various therapeutic and disinfectant additives to the basic good neutral soap, medical soap is obtained: boron, formalin, vaseline, lanolin, ichthyol, etc. It is used as directed by doctors, for skin diseases, against dandruff and for disinfection.

Hardness soap depends mainly on the nature of the fatty acids that make up the soap. Harder fats make harder soaps. For this purpose, liquid vegetable oils are subjected to a special treatment using hydrogen gas, in which they pass into a solid state (“salomas”). For getting soap usually take a mixture of various fats and oils. In toilet and children's soaps, there are fewer substitutes than in household ones.

When cooking fats with caustic soda, the resulting soap contains a certain amount of water and impurities that were in the fatty raw material. To remove impurities and some of the water, salt is added to the heated soap. When peeling off soap floats up, while pollution and most of the water settle down below. Upper layer soap contains about 60% fatty acids. This layer is separated from the rest of the mass and thus a 60% sound soap is obtained.

Soap with a high content of fatty acids is obtained by drying the sound. To do this, it is crushed and, after drying, pressed, giving the shape of pieces. This is how they cook dressing soap.

Liquid soap obtained by cooking various vegetable oils (linseed, cottonseed, etc.). The most common of them are green and oleic. These soap wash in cold water much better than solid ones. They are used to make shampoos, shaving pastes and, as a basis, in the manufacture of some types of medical soaps.

The quality of different varieties soap determined by color, smell, content of impurities of unsaponifiable substances, alkali, impurities, etc. Soap with an admixture of unsaponifiable substances gives less foam.

If hands become sticky after washing and drying, this indicates that soap contains a lot of unsaponifiable or unsaponified substances or an excess of substitutes - rosin, etc. Soap With an excess of alkali, it usually causes irritation of the skin of the hands and, with prolonged use, can lead to the formation of ulcers, cracks, etc. Such soap do not use for washing the head and face, as well as for washing woolen and silk items.

"Soap shavings" (soap flakes) - is a concentrated soap made from high quality fats. It is used for washing delicate fabrics, lace, colored cambric and voile, woolen and silk fabrics and knitwear.

I found information about soap a couple of months ago, I checked some facts, they are true. Maybe someone will be interested or need someone. Lots of information. After reading a lot of forums, here are the reviews I found:

“Do you have laundry soap in your apartment? If not, then be sure to get it and let it lie just in case! I have heard about its benefits many times. Once, as a child, I was bitten by a neighbor's dog and my grandmother, before dragging me to the hospital, washed the wound with laundry soap. I screamed, pulled out, but the granny tried to wash the wound as thoroughly as possible. By the way, in the hospital they praised us for this and recommended that we always do this.

“My classmate (it was a long time ago!) Had thick, luxurious hair below her buttocks. Such that she could not comb herself. Everyone gasped after her, but I could not resist and asked how she was caring for them. The first wash - shampoo (wash off the main dirt), then - household. soap. I tried! Six months later, instead of my three thin hairs - cool hair and 0 dandruff. I've been happy with my hair for 9 years."
