GLYCERYL DIARACHIDATE.

Valuable CAS 89648-24-8 / 127039-55-8 / SKIN CONDITIONING - EMOLLIENT

Glyceryl Diarachidate is a diester derived from glycerin and arachidic acid, functioning as a highly effective skin conditioning agent and emollient. It enhances skin suppleness by forming a lubricating barrier, contributing to a visibly smoother and softer complexion while supporting moisture retention.

Summary

emollient skin conditioning

Science

Mechanism of Action

This ingredient primarily acts as a skin conditioning agent and emollient by forming a non-occlusive film on the skin's surface. It effectively lubricates the skin, reducing flaking and improving tactile smoothness and softness. By remaining within the stratum corneum, it aids in fortifying the skin's barrier function and helps to preserve humidity in cosmetic formulations.

Stability

Glyceryl Diarachidate is immiscible with water and not easily soluble, though it can be dispersed in hot water with significant oscillation. It exhibits good solubility in various organic solvents, including ethanol, benzene, acetone, mineral oil, and fixed oils. No specific optimal pH range for ester stability was identified; however, its fatty acid components generally maintain stability across a wide pH range of 1-14.

Conflicts

  • Careful control of the 1,2-diester isomer content is crucial, as high concentrations may potentially induce epidermal hyperplasia.

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Glyceryl Diarachidate is safe for use in cosmetics and personal care products, provided the content of the biologically active 1,2-diester isomer is not high enough to induce epidermal hyperplasia. Diglycerides, encompassing Glyceryl Diarachidate, are also approved by the FDA as indirect food additives and are Generally Recognized as Safe (GRAS) for food additive use. While a specific maximum concentration for Glyceryl Diarachidate is not explicitly stated, it is considered safe within the current practices and concentrations typical for its class, with other glyceryl diesters reported up to 43% in certain applications.
