Why does the soap wash?

For two thousand years, we use foaming pleasure, without thinking about where it came from and how it works.

Soap was known in ancient times - somewherefor 3000 years before our era. The inhabitants of Mesopotamia knew how the soap was made, the Sumerian peoples used it, the inhabitants of Egypt and Ancient Rome also did not do without it. Soap making as art became known to the European population in the 1930s, when industrial production was established.

Our ancestors used a soap root (rootssome plants, of which foam is obtained, similar to the soap), which they washed and washed. Soap in the form in which it is known now, then was not. But also the drying of the skin, irritation with its chemical additives and flavors, too, was not.

What does soap consist of?

Detergent properties are not water, and soap. Water can not wash away dirt, especially entrained. However, to wash really with one water without soap is impossible. Therefore, if you set a goal and understand why it washes soap, you should first remember what it was made of. The main component of soap remains alkali. Alkali has the property of splitting fats of both animal and vegetable origin. They are the basis of dirt, which we wash off with soap foam.

What is the detergent in the soap?

If you consider soap foam, you can easilySee that it consists of millions of small rainbow bubbles. When they come into contact with water, the surface of the bubbles becomes surrounded by soap molecules. The surface of the water stress decreases, and the ability to wet is increased.

As a result of soaping, wetting is improvedsurfaces, so the dirt particles, covered with soap bubbles, are more easily separated from the surface. Because of the enveloping qualities of soap molecules, dirt particles can not again adhere to the wash surface. They are washed off with water. To understand why soaps wash, it is not difficult. It consists of a combination of fats and alkali due to this composition and has detergent properties.

Additives

Everything else is additives. In the soap, flavorings (or essential oils in more expensive soap varieties) are added to improve the flavor. There are additives for softening the hands and body. Antibacterial substances in the soap are needed for the disinfection of the skin and the destruction of bacteria and microbes. There are also moisturizing agents that protect the skin from overdrying. You can choose a soap with any additives that are most suitable for your skin.
