Deceth-3 (inci)

Deceth-3 is a polyoxyethylene ether of decyl alcohol which is used as emulsifier in cosmetic products.

Polyalkylene glycol ethers are non-ionic compounds whose lipophilic part consists of fatty alcohols, e.g. decyl alcohol. 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. Deceth-3, for example, is the INCI designation for a polyoxyethylene ether with 3 ethylene oxide units per mol.
