C10-40 ISOALKYLAMIDOPROPYLETHYLDIMONIUM ETHOSULFATE.

Valuable / ANTISTATIC, HAIR CONDITIONING

A quaternized biomimetic lipid derivative of 18-methyleicosanoic acid (18-MEA), the natural fatty acid coating found on healthy hair and skin surfaces. This advanced conditioning agent restores hydrophobicity to damaged keratin structures by ionically bonding to negatively charged areas, effectively rebuilding the protective lipid barrier that prevents transepidermal water loss.

Science

Functions as a targeted lipid barrier replenisher by depositing onto damaged (negatively charged) keratin surfaces through ionic attraction. Once deposited, it forms a biomimetic 18-MEA layer that restores natural hydrophobicity, strengthens barrier function, and provides wash-resistant conditioning effects.
