BRASSICYL ISOLEUCINATE ESYLATE.

Valuable CAS - / ANTISTATIC, EMULSION STABILISING, HAIR CONDITIONING

A high-performance, 100% plant-derived cationic amino lipid that bridges the gap between green chemistry and clinical efficacy. It serves as a sophisticated structuring agent that imparts a luxurious, powdery finish to skincare while significantly reinforcing the cutaneous barrier.

Emulsion stabilizing Skin conditioning Barrier restoration Texture enhancer

Science

By organizing into lamellar liquid crystalline gel networks (LCNs), it creates a biomimetic structure that mirrors the skin's natural lipid bilayer. This molecular arrangement enhances the delivery of actives, reduces trans-epidermal water loss (TEWL), and provides a persistent, velvety protective film on the stratum corneum.

As a primary emulsifier and texture modifier, it is typically used at functional levels (1.5%+) rather than trace amounts. Use below 1% in emulsions may indicate its inclusion for marketing claims rather than structural performance.
