In the application of surfactants in cosmetics, anionic surfactants are more and more widely used. They have rich foaming property, good emulsifying ability, moderate cleaning power and special skin affinity, which can meet the requirements of hair cleansers. Cationic surfactants can be used in hair care products, Including hair conditioner and hair styling gel, it is also a very effective antistatic agent to make hair more supple. Zwitterionic surfactant itself has low toxicity, low irritation to skin and eyes, so it is widely used.

The main types of zwitterionic surfactants are amino acid surfactants, imidazoline surfactants and betaine surfactants. Amino acid zwitterionic surfactants have mild action on hair and skin, good foaming and emulsifying properties, strong decontamination ability, good biodegradation performance, and also have good antibacterial and bactericidal properties. Therefore, amino acid type surfactants will be a good development direction; non-ionic surfactants are mainly used as emulsifiers, especially ethoxylated surface activity It can be used as O / W emulsifier. In addition, it can also be used as a solubilizer for oily components. In addition, some special surfactants are mainly used as auxiliary surfactant in foam shampoo and bath preparations.

The main functions of surfactants in cosmetics include emulsification, dispersion, solubilization, foaming, cleaning, lubrication and softening. Surfactants are widely used in cosmetics and play an important role. Cosmetics can clean, protect and beautify human face, skin surface, hair and mouth. There are many kinds of cosmetics and their classification methods are also different.

According to the tanning process, anionic surfactants can be first applied to the soaking process as soaking AIDS. The commonly used anionic surfactants are: penetrant t (sodium succinate and dioctyl ester sulfonate), dla-1 (sodium petroleum sulfonate), M65 (sodium alkyl sulfonamide acetate), BX (sodium dibutyl benzene sulfonate), ramiban a, etc. But from the practical application effect, the immersion effect of nonionic surfactant is better.

The main anionic surfactants for degreasing are fatty alcohol polyoxyethylene ether phosphate (PK-3, pk-9), dodecyl benzene sulfonate (LAS), alkyl sulfonate as, alkyl phosphate salt (PL-1), ramibang a, BX polyether amine, etc. Degreaser is mainly composed of anionic and nonionic surfactants, which can also be used in water immersion, liming, acid leaching and other processes. In fatliquoring agents, anions are generally used as emulsifiers in combination with fatliquoring agents to increase their stability to acid, alkali and salt. They are absorbed by leather and are not easy to demulsify. They combine with leather collagen to make the leather feel comfortable, soft and full, and have certain washing resistance.
