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, 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). In the designation of fatty alcohol polyglycol ethers, the inserted numbering means the average number of ethylene oxide units per mole. Laureth-10, for example, is the INCI designation for a polyoxyethylene ether with 10 ethylene oxide units per mole.

The different representatives are Laureth-1 to Laureth-40.
