Fatty alcohol polyoxyethylene ether
Also known as AEO, the general formula is RO(CH2CH2O)nH, where R=C12-18, n=3-20. Commonly used fatty alcohols are lauryl alcohol, cetyl alcohol, oleyl alcohol, etc. Purpose of use in cosmetics: emulsifier, cleanser, emollient, dispersant.
For example: ceteareth-10; INCI name: CETEARETH-10; alias: AEO-10; ceteareth-10. White waxy body, insoluble in water, HLB value is 12.9.
Structural formula: n is 10

Alkylphenol polyoxyethylene ether
Also known as TX; OP, alkylphenol polyoxyethylene ether-n, the raw material with n value greater than 8 has better water solubility.
For example: nonylphenol polyether-10; INCI name: NONOXYNOL-10; alias: TX-10, nonylphenol polyoxyethylene (10) ether. Transparent liquid with good functions of wetting, emulsifying, dispersing, solubilizing, foaming, defoaming and decontamination, HLB value is 13.3.
Structural formula:

Polyol polyoxyethylene ether fatty acid ester
A typical representative raw material is polyoxyethylene sorbitan (Tween), also known as: polysorbate, Tween, which is a condensation product of Span and ethylene oxide. The water-based group is a polyoxyethylene group, so it has strong hydrophilicity. Includes T-20/21/40/60/61/65/80/81/85.
For example: Polysorbate-20; INCI name: POLYSORBATE 20; Alias: T-20, Tween 20, polyoxyethylene (20) sorbitan monolaurate.
The raw material is a light yellow to yellow viscous liquid at room temperature with a faint characteristic odor. Soluble in water, ethanol, methanol, ethyl acetate, insoluble in mineral oil and petroleum ether. Can be used as emulsifier, dispersant, solubilizer.
Its chemical structural formula is:
where w+x+y+z=20

Alkanolamides
Alkanolamides are prepared by condensation of fatty acids and monoethanolamine (MEA) or diethanolamine (DEA). The hydrophilic groups are amide groups and hydroxyl groups, and the lipophilic groups are long-chain alkyl groups. The main purpose of use in cosmetics is thickener and foam stabilizer.
Example: Cocamide DEA, INCI name: COCAMIDE DEA; Alias: Coconut fatty acid diethylamide; 6501; Cocoic acid diethanolamide; colorless viscous liquid, soluble in water, has good foaming, foam stabilization, Antistatic effect.
In the “Safety and Technical Specifications for Cosmetics (2015 Edition)”, it is a restricted substance with quality specifications: when using this raw material, do not use it together with the Nitrosating system; avoid the formation of nitrosamines; in the product The maximum content of secondary alkane amines is 0.5%, and the maximum content of nitrosamines is 50μg/kg; the maximum content of secondary alkane amines in raw materials is 5%; stored in nitrite-free containers.
Structural formula: (1:1 type alkylamide DEA, where R is coconut oil acid)

Polyol monofatty acid ester
Polyols are used as raw materials for esterification with fatty acids. The lipophilic group is the long carbon chain of the fatty acid, and the hydrophilic group is the unesterified hydroxyl group. Including fatty acid esters of glycerol and sorbitan esters.
Glycerin Fatty Acid Ester
Glycerin fatty acid esters that can be used as surfactants are monoesters and diesters synthesized from glycerol and fatty acids, and are mainly used as emulsifiers.
For example: glyceryl stearate; INCI name: GLYCERYL STEARATE; alias: glyceryl stearate (mono) ester, white flake, insoluble in water. Mainly used as emulsifier, co-emulsifier and emollient.
