C10-40 ISOALKYL ACID GLYCERIDE.

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

A sophisticated biomimetic emollient that delivers branched iso-fatty acids to restore the skin's natural lipid architecture. This glyceride ester enhances barrier function by integrating into intercellular lipid layers, reducing water loss while improving active ingredient penetration. Particularly effective for compromised or mature skin requiring structural lipid replenishment.

Summary

emollient skin conditioning barrier repair penetration enhancer occlusive agent

Science

Mechanism of Action

Provides branched C10-40 iso-fatty acids that structurally mimic the skin's natural 18-MEA lipids, integrating into intercellular lipid lamellae to restore barrier integrity, reduce transepidermal water loss, and create lipid pathways that enhance active ingredient delivery into the stratum corneum
