Laneth

Laneth(e) are the polyoxyethylene ethers of lanolin alcohols (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. Laneth-10, for example, is the INCI designation for a polyoxyethylene ether with 10 ethylene oxide units per mole. Representatives are Laneth-5, Laneth -10, Laneth -12, Laneth -14, Laneth -16, Laneth -20, Laneth -25. Laneth act as surfactants.
