AVOCADO OIL PEG-11 ESTERS.

Valuable CAS 103819-44-9 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A sophisticated, water-dispersible derivative of avocado oil that merges the lipid-replenishing benefits of natural fatty acids with the functional performance of a non-ionic surfactant. It serves as a multifunctional emollient that enhances product texture while supporting the skin's protective moisture barrier.

emollient emulsifying surfactant skin conditioning

Science

This ingredient functions by reducing interfacial tension between oil and water phases, facilitating stable emulsions and effective cleansing. Upon application, the avocado oil moiety delivers essential oleic and linoleic acids along with vitamins A and E to the stratum corneum, reinforcing the lipid matrix and significantly reducing transepidermal water loss (TEWL).
