C10-40 ISOALKYL ACID.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

A biomimetic fatty acid complex derived from lanolin that functions as a sophisticated lipid barrier repair agent. This branched-chain saturated fatty acid mixture mimics natural skin lipids like 18-MEA, effectively filling gaps in the intercellular cement to restore barrier integrity. Its unique molecular structure provides exceptional stability while delivering targeted emollient and skin-conditioning benefits.

Summary

emollient skin-conditioning viscosity controlling barrier repair

Science

Mechanism of Action

Functions as a biomimetic lipid replenisher by mimicking the complex lipids found in skin's intercellular cement and hair's protective cuticle layer. It systematically fills gaps in the lipid barrier structure, preventing transepidermal water loss (TEWL) while re-hydrophobicizing compromised surfaces to restore smoothness and barrier resilience.
