Isodeceth-4 (inci)

Isodeceth-4, is the polyoxyethylene ether of isodecyl alcohol, the lipophilic part of which consists of isodecyl alcohol. The substance acts as emollient (makes the skin supple and smoothes it), emulsifier (changes the interfacial tension of liquids like water and oil so that they can be mixed together) and surfactant (washing-active substance).

Polyalkylene glycol ethers are non-ionic surfactants. Their hydrophilic part is formed by short-chain polyethylene glycols (polyoxyethylene). In the designation of alcohol polyglycol ethers, the inserted numbering means the average number of ethylene oxide units per mole. Isodeceth-2, for example, is the INCI designation for a polyoxyethylene ether with 2 ethylene oxide units per mole.
