CETEARYL BEHENATE.

Valuable CAS 246159-35-3 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT, SKIN PROTECTING

A high-performance long-chain wax ester that serves as a specialized occlusive and structural agent in precision skincare. It bridges the gap between traditional waxes and emollients, offering a sophisticated, breathable shield that reinforces the skin's lipid barrier without a heavy residue.

Summary

Occlusive Emollient Skin Protectant Structuring Agent

Science

Mechanism of Action

This lipophilic ingredient functions by creating a semi-permeable protective film across the epidermis, which significantly mitigates trans-epidermal water loss (TEWL). By infiltrating the interstitial spaces between corneocytes, it restores surface smoothness and enhances skin elasticity through lipid replenishment.

Key findings

  1. 01 Human Repeat Insult Patch Tests (HRIPT) confirmed that concentrations of 1.5% and higher are non-sensitizing to the skin.
  2. 02 Clinical product analysis shows that concentrations between 5.7% and 8.6% provide optimal structural integrity for dermatological barrier repair sticks.
