Emulsifiers are another important aspect of surfactant use. There are 200 to 300 kinds of emulsifiers available for cosmetics, with a wide variety and different performance.
|Chemical Name||Trade Name||Characteristic||Main Features|
|Sodium stearate||_||White solid powder||It has good emulsification performance and generates O/W type emulsion with low price. But strong alkaline, high water quality requirements|
|Triethanolamine stearate||_||Creamy waxy solid||It is an excellent emulsifier for O/W type emulsions with low PH value. But long storage has the tendency to make the product yellow|
|Calcium Stearate||_||_||W/O type emulsifier, but emulsification efficiency is not high|
|Dodecyl phosphate potassium salt||PKPL-1||White, transparent and sticky liquid||Emulsification, softness and anti-static properties|
|Dodecyl polyoxyethylene ether phosphate monoethanolamine||APEA||Carboxylate-type imidazoline||Can be used as an emulsifier for creams. Very low irritation to skin, suitable for children’s skin care products|
|Polyoxyethylene stearate||SE Emulsifier||Light yellow cream||Poor detergency, foaming power and wetting performance, poor stability, but low cost, less foam and better biodegradability|
|Binary (ternary) alcohol esters||_||_||Mostly oil-soluble W/O emulsification|
|Fatty acid monoglycerides||_||_||Good emulsification ability and safety, often used as W/O emulsifier can become self-emulsifier after adding metal fatty acid salt|
|Sorbitol monolaurate dehydrate||Futures -20||Amber or brown-orange oily liquid||Used as an emulsifier itself is insoluble in water, rarely used alone. Often used in combination with Tween series|
|Sorbitan monopalmitate dehydrate||Span-40||Yellowish brown waxy substance|
|Sorbitol monostearate dehydrate||Span-60||Yellowish brown waxy solids|
|Sorbitan monooleate dehydrate||Span-80||Amber colored viscous oily liquid|
|Polyoxyethylene dehydrated sorbitan monolaurate||Tween-20||Amber colored oily liquid||Good water solubility and dispersibility, often used in combination with Span|
|Polyoxyethylene dehydrated sorbitol monopalmitate||Tween-40||Amber colored oily liquid|
|Polyoxyethylene anhydrous sorbitol monostearate||Tween-60||Amber colored oily liquid|
|Polyoxyethylene dehydrated sorbitan monooleate||Tween-80||Amber colored oily liquid|
|Methyl glucoside stearate||MS||Yellow soft solid||It has good safety, solubility, moisturizing and emulsifying properties, thickening ability and low cost of biodegradability|
The main effect is antistatic, making hair easy to comb, soft and shiny. Conditioning agents are mainly cationic surfactants.
Difficult to dissolve in water grease, spices, drugs (such as oil-soluble vitamin A), etc., can be dispersed in water by emulsifiers into very small particles and a transparent solution. Emulsifier with this performance, can be called solubilizer. Polyoxyethylene sorbitol fatty acid ester (Tween) series and polyoxyethylene fatty alcohol ether (Brij) series and other emulsifiers are more soluble. Its dosage generally depends on the nature of the dispersed phase, content, but also by mutual solvents (such as alcohol). Mainly used in the production of make-up, hair growth and hair care agent.

Foam stabilizers are surfactants that have the effect of prolonging and stabilizing foam and maintaining its long-lasting performance. Effective foam stabilizers in the detergent and cosmetic industries are fatty alcohol amides.
