Hydrogenated talloweth-25 (inci)

Hydrogenated talloweth-25 is used in cosmetic formulations. The substance acts as emulsifier (changes the interfacial tension of liquids like water and oil so that they can be mixed together), surfactant (washing-active substance).

Talloweth(e) are the polyoxyethylene ethers of hardened fatty acids which are obtained from beef tallow (see also: 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 is obtained from 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. Talloweth-25, for example, is the INCI designation for a polyoxyethylene ether with 25 ethylene oxide units per mole.
