BEHENYL BEHENATE.

Valuable CAS 17671-27-1 / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

A high-purity monoester wax and structural lipid that bridges the gap between texture enhancement and barrier protection. It is highly bio-compatible because its primary component, behenic acid, is a fatty acid found naturally in the skin's own sebum.

Summary

emollient skin conditioning viscosity controlling barrier repair

Science

Mechanism of Action

Behenyl Behenate functions as a sophisticated occlusive emollient, creating a breathable, non-greasy film that reinforces the stratum corneum. At the structural level, it organizes lipid phases into a 'card-house' network of plate-like crystals, which improves the thermal stability of formulas and prevents trans-epidermal water loss (TEWL).

Key findings

  1. 01 Demonstrated a four-fold increase in formulation hardness and structural integrity when utilized at a 30% ratio within wax phases (Journal of Oleo Science, 2022).
  2. 02 Identified as a high-purity emollient that effectively prevents water loss while maintaining high bio-compatibility (International Journal of Toxicology, 2015).
  3. 03 Proven to stabilize solid lipid nanoparticles (SLNs) at 5% concentration, significantly improving the delivery of lipophilic vitamins (Pharmazie, 1995).

Because it serves dual roles as a texture modifier and an active emollient, it is rarely 'dusted' at negligible levels; however, concentrations below 1% may provide consistency benefits without delivering the full clinical occlusive barrier support.
