APRICOT KERNEL OIL PEG-40 ESTERS.

Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A sophisticated, multifunctional derivative of apricot kernel oil that combines the deep conditioning properties of natural lipids with the high-performance functionality of a water-soluble surfactant. This ingredient serves as a bridge between oil and water phases, allowing for the creation of elegant, non-greasy textures that effectively cleanse while replenishing the skin barrier.

Summary

Emollient Emulsifying agent Surfactant Solubilizer

Science

Mechanism of Action

This ingredient functions through a dual-action molecular structure. The polyethylene glycol (PEG) chain provides hydrophilic properties that reduce surface tension for effective cleansing and solubilization of actives. Simultaneously, the apricot kernel oil component delivers essential oleic and linoleic fatty acids that integrate into the stratum corneum, reinforcing the lipid matrix and significantly reducing transepidermal water loss (TEWL).

While often used at low levels as a solubilizer (0.5-2%), it is rarely 'dusted' because it serves a clear functional purpose in stabilization; however, for active barrier replenishment or as a primary cleanser, concentrations should ideally exceed 5%.

Stability

Possesses a high HLB value of approximately 13, making it an excellent solubilizer for essential oils and fragrance in aqueous systems. It exhibits a 'cloud point' effect where water solubility may decrease at elevated temperatures.
