About

A PEG-derived polymer with a diamondoid cage structure, used as a film-forming or conditioning agent in cosmetics.

This is a PEG-2300 extended polymeric ingredient with an adamantyl (diamondoid cage) group and a carboxamide linking group. PEG polymers of this chain length are restricted in EU Annex III for use in leave-on products above certain concentrations due to potential ethylene oxide impurities (CMR concerns). The adamantyl moiety is novel and not extensively toxicologically profiled, warranting a middle-ground safety score.
