Poloxamer 234 (inci)

Poloxamers" are low-foaming and foam-absorbing, non-ionic surfactant block polymers composed of polyethylene oxides and polypropylene oxides. Poloxamers are used for dispersion and emulsification in cosmetics (also in the chemical-technical industry and medicine). The polyethylene oxide part of the polymer is water-soluble, whereas the polypropylene oxide part is not, so that this results in the special amphiphilic properties of the compounds.

Poloxamer 234 is a white waxy powder which is used in cosmetic formulations. The substance acts as an emulsifier (surface-active substance which is used in cosmetic products as an auxiliary agent to combine two immiscible liquids - e.g. oil and water - into one emulsion) and as a surfactant (washing-active substance; improves the even distribution of the products during application).
