About
Hydroxylated lipid fraction from cow's milk fat — a barrier-supportive emollient. Animal-derived; allergen risk for dairy-sensitive users.
Hydroxylated milk glycerides (CAS 144635-07-4) are obtained by chemically hydroxylating the triglycerides found in cow's milk fat, creating polar lipids that integrate well with the stratum corneum. They are used as skin-conditioning emollients and as co-emulsifiers in dry-skin formulas. No regulatory restrictions in the EU or US at cosmetic concentrations; however, specific cosmetic clinical evidence is limited and the ingredient is animal-derived. Cross-reactivity in users with milk-protein allergy is theoretically possible but rarely documented. No CMR, GHS, or endocrine concerns reported.
