What are the ingredients of soap？

There are many kinds of ingredients in soap, generally animal fatty acids, sodium hydroxide, synthetic pigments, synthetic fragrances, preservatives, antioxidants, foaming agents, hardeners, viscous agents, and synthetic surfactants.

Soap is an alkali salt with a pH of 9.5-10 composed of fat, oil and salt. It is the simplest anionic surfactant, and it decontaminates by forming soap salt to emulsify the surface material of the skin. Compared with soap, soap has low alkalinity, and high-fat content, and is less irritating to the skin than soap. But for different groups of people, the choice of soap is also different.

Soap is a widely accepted personal cleaning product, with strong cleaning ability and low price, and has become a necessity in people’s life. However, the use of medicinal soaps must use products with long-term deodorization, broad-spectrum sterilization, and low irritation to the skin, such as sulfur soap, borax soap, etc. Try to use recently produced soap products, because the unsaturated fatty acids contained in the soap raw materials will be oxidized by oxygen, light, microorganisms, etc., and even rancidity may occur. At the same time, the water in the soap will also be lost, affecting the use effect.
