Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A copolymer of polyethylene glycol and polycaprolactone used as an emollient and film-forming agent in cosmetic formulations. It is listed in EU Annex III (entry III/186) with restrictions on purity, particularly limiting 1,4-dioxane and ethylene oxide residues.

This copolymer functions primarily as an emollient and film former in cosmetic products. The EU CosIng database lists it under Annex III/186, restricting residual 1,4-dioxane (≤10 ppm) and ethylene oxide content due to carcinogenic concerns from these manufacturing by-products. PEG polymers of high molecular weight generally have low skin penetration, and this ingredient is considered safe at reported purity levels when properly manufactured.

Skin benefits

  • Emollient properties - softens and smooths skin
  • Film-forming ability - provides protective barrier
  • Used in emulsification systems

Known concerns

  • Potential 1,4-dioxane contamination from ethoxylation process
  • Potential ethylene oxide residue
  • Not recommended for damaged or compromised skin barriers
