Laneth-75 (inci)

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-75 is the INCI designation for a polyoxyethylene ether with 75 ethylene oxide units per mole.

Laneth-75 acts as an emulsifier (changes the interfacial tension of liquids such as water and oil so that they can be mixed together) and surfactant (washing-active substance).
