Laundry soap looks inconspicuous, but surpasses modern means in its washing and antibacterial properties, and given its complete safety for the body, there is no doubt that the ugly red bar can be actively used in everyday life.
Composition of laundry soap
Laundry soap consists of salts of fatty acids and various additives that improve the washing properties of soaps. The color, smell, and detergent properties of soap directly depend on the raw material from which it is made. So, soap, which mainly consists of saturated fatty acids - lauric, stearic, palmitic - foams only in hot water, since these acids have a melting point of 44 to 70 degrees, while this soap has very good washing properties and a stable solid texture.
Soap made of unsaturated fatty acids has a paste-like consistency and performs worse with impurities, but can also be washed in cold water.
Household soap made from technical animal fats has the best properties. Soap, which contains more fatty acids of plant origin, foams worse, quickly soaks, rancid.
The classic laundry soap, prepared according to a recipe created in the Soviet Union, contains only sodium salts of fatty acids and oils, sodium chloride, water, caustic and soda ash. It is believed that just such a soap in full possesses the best qualities inherent in a real laundry soap.
Modern manufacturers of laundry soap are trying to make it more attractive to customers by adding various components: fragrances to improve the smell of soap, glycerin - so that the soap does not dry the skin, bleaching substances that brighten the soap.
The properties of laundry soap are best manifested when washing and washing in softened water.
According to the percentage of fatty acids, laundry soap is divided into three groups: 72% soap, 70% soap and 65% soap. The higher the percentage of fatty acids, the higher the bactericidal and detergent properties of the soap. Usually this percentage is squeezed directly onto a bar of soap.
