Surf A20, Surf A25 are used as emulsifying agents for the production of creams, liquid emulsions, gels and other cosmetic and pharmaceutical preparations. Extremely good results are obtained with mixtures of the various Ceteareth serials.

The products are suitable emulsifying agents for oil-in-water types of emulsion. All conventional hydrophobic cosmetic raw materials can be emulsified to yield very stable oil-in-water emulsions.
