C18-29 ALKANE.

Valuable CAS 64742-55-8 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

A high-purity, long-chain hydrocarbon that serves as a sophisticated emollient and moisture-locking agent. It provides a non-greasy, silky finish to formulations, acting as a stable and sustainable alternative to volatile silicones.

Occlusive Emollient Solvent Texture Enhancer

Science

It creates a breathable, hydrophobic barrier on the stratum corneum, significantly curbing transepidermal water loss. By infiltrating the microscopic spaces between skin cells, it smooths texture and reinforces the lipid matrix for enhanced barrier resilience.
