Diethylamine laureth sulfate (inci)

Diethylamine laureth sulfate is a substance used in cosmetic formulations. Diethylamine laureth sulfate acts as a surfactant. The substance enhances foam formation and improves volume, structure and durability of the foam.

The polyoxyethylene ethers of lauryl alcohol are called laureth(s) (for comparison see: steareth as polyoxyethylene ether of stearyl alcohol and others). Polyalkylene glycol ethers are non-ionic surfactants, the lipophilic part of which consists of fatty alcohols (e.g. lauryl alcohol, palmitic alcohol, stearyl alcohols etc.). The hydrophilic part is formed by short-chain polyethylene glycols (polyoxyethylene).
