Isoceth-30 stearates (inci)

Isoceth-30 stearate is a substance used in cosmetic formulations. Isoceth-30 acts as emulsifier (changes the interfacial tension of liquids like water and oil so that they can be mixed together) and surfactant.

Isoceteth(s) are the polyoxyethylene ethers of isocetyl alcohol (for comparison see: laurethe as polyoxyethylene ether of lauryl alcohol; steareth as polyoxyethylene ether of stearyl alcohol and others).

Polyalkylene glycol ethers are non-ionic surfactants whose lipophilic part consists of fatty alcohols (e.g. lauryl alcohol, palmitic alcohol, stearyl alcohols etc.). The hydrophilic part is formed by short-chain polyethylene glycols (polyoxyethylene). In the designation of fatty alcohol polyglycol ethers, the inserted numbering means the average number of ethylene oxide units per mole. Isoceteth-30, for example, is the INCI designation for a polyoxyethylene ether with 30 ethylene oxide units per mole.
