There are three kinds of common shower gels in the market: surfactant, soap-based and compound.
1. Surfactant type
It is mainly compounded by surfactant with washing function, and its pH value is close to skin, so it is gentle and smooth, and it is easy to cause the feeling of not being cleaned if it is not compounded well.
2. Soap-based
Also known as liquid soap, it is improved according to the principle of soap making. This product is rich in foam and easy to clean. After washing, the skin is fresh, but it feels tight.
3. Compound type
The combination of surfactant and soap base combines the advantages of both, but it is difficult to develop. The development of shower gel should consider the following properties: foam and detergency, gentleness or irritation, fragrance, skin feeling and appearance.
Extension material: alkyl phosphate is a very important surfactant, which has excellent antistatic property, emulsion dispersibility, lubricity, cleaning property, acid and alkali resistance, and is widely used in plastics, leather, pesticides, paper making, coatings, metallurgy, cosmetics, medicine, daily chemicals and other industries.
Compared with As, AOS, LAS and AEs, monoalkyl phosphate (MAP) has the advantages of less irritation, gentleness, easy washing, rich foam, delicacy and strong emulsifying ability, and is an excellent raw material for skin care products. MAP can be mixed with surfactants and soap-based shower gel, which can achieve good results.
