PEG-240/Hdi Copolymer Bis-Decyltetradeceth-20 Ether
PEG-240/HDI Copolymer Bis-Decyltetradeceth-20 Ether is a polymeric ingredient formed by the copolymerization of a PEG-240 chain with hexamethylene diisocyanate (HDI), end-capped with decyltetradeceth-20 fatty ether groups. Its full INCI chemical description is: poly(oxy-1,2-ethanediyl), α-hydro-ω-hydroxy- (240 mol EO average), copolymer with 1,6-hexanediisocyanate, diether with alpha-(2-decyltetradecyl)-omega-hydroxypoly(oxy-1,2-ethanediyl) (20 mol EO average). It is commonly found in gel-type formulations such as sleeping masks, jelly primers, and gel creams. According to CosIng, its official functions are stabilising and viscosity controlling.
This ingredient primarily serves as a viscosity controller and stabiliser in cosmetic formulations, helping to create and maintain gel-like textures. It contributes to the characteristic jelly or pudding consistency seen in sleeping masks and gel primers. No direct skin-active benefits are described in the source.
