Laureth-6 (inci)

Laureth(s) are the polyoxyethylene ethers of lauric alcohol (for comparison see: Cetethe as polyoxyethylene ether of cetylacohol; 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. Laureth-6 is the INCI designation for a polyoxyethylene ether with 6 ethylene oxide units per mole.

Laureth-6 acts as emulsifier (changes the interfacial tension of liquids such as water and oil so that they can be mixed together) and surfactant (washing-active substance).
