BUTTER GLYCERIDES.

Valuable / SKIN CONDITIONING

Shea butter-derived fatty acid esters that deliver enhanced skin barrier repair through bioavailable essential fatty acids. These refined glycerides offer superior moisturization compared to traditional butter forms while maintaining excellent skin compatibility. Their dual emollient and emulsifying properties make them versatile multifunctional ingredients in precision skincare formulations.

Science

Mechanism of Action

Functions by delivering oleic, stearic, and linoleic acids directly to the stratum corneum to rebuild compromised lipid barriers. Creates a semi-occlusive protective film that reduces transepidermal water loss while simultaneously replenishing intercellular lipids for enhanced skin flexibility and moisture retention.
