General informationThis section has been translated automatically.
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 indicates the average number of ethylene oxide units per mole. Laneth-5, for example, is the INCI designation for a polyoxyethylene ether with 5 ethylene oxide units per mole.
Hydrogenated laneth-5 acts as an emulsifier (changes the interfacial tension of liquids like water and oil so that they can be mixed together), as a swelling agent (reduces the bulk density of cosmetic products) and skin care product.

Laneth(e) are the polyoxyethylene ethers of fatty alcohols which are obtained from wool wax(lanolin = INCI designation of wool wax) (comparatively: laurethe as polyoxyethylene ether of lauryl alcohol; steareth as polyoxyethylene ether of stearyl alcohol and others).
