Nonionic surfactants have excellent washing properties and strong decontamination ability even at low concentration; Less foam; Easy to be made into liquid detergent; It does not dissociate when dissolved in water and is not sensitive to hard water and electrolyte; The critical micelle concentration is very low and has good solubilization ability; Emulsification, dispersion, wetting and anti redeposition properties are also very excellent; High stability, acid and alkali resistance, easy biodegradation. Therefore, it is widely used to prepare various detergents, and its variety and dosage are increasing year by year.

1) Polyoxyethylene surfactant is prepared by ethoxylation of hydrophobic raw materials with active hydrogen atoms in groups such as - Oh, - COOH, - NH2 and - CONH2 with ethylene oxide (EO). Ethoxylation is an important technology for the production of surfactants, especially non-ionic surfactants. This kind of surfactant has many functions, such as dispersion, penetration, emulsification, solubilization, wetting, foaming and sterilization. It is widely used in cosmetics.

2) Polyoxyethylene anionic surfactant is a kind of surfactant, which is widely used. Polyoxyethylene cationic surfactants are mainly used as fungicides and bacteriostatic agents in cosmetics. They can be used in hair care products, including hair conditioner and hair styling gel. They are effective antistatic agents and can make hair soft. Generally speaking, it has no decontamination ability and cannot be used in combination with anionic surfactants.

3) Polyoxyethylene nonionic surfactant has the functions of wetting, penetration, emulsification and solubilization. They are a large class of non-ionic surfactants with large production and wide application. They are widely used in cosmetics.
