COPERNICIA CERIFERA WAX.

Valuable CAS 8015-86-9 / DEPILATORY

Copernicia Cerifera Wax, commonly known as Carnauba Wax, is a natural plant-derived wax highly valued in skincare for its ability to refine product texture and enhance stability. It functions as an emollient, forming a protective layer on the skin to reduce moisture loss and contribute to a smoother, softer feel.

Summary

Emollient Viscosity controlling Film forming Thickening agent Oil-binding Thermal stabilizer

Science

Mechanism of Action

This wax operates on the skin by forming a continuous, protective barrier that efficiently minimizes trans-epidermal water loss, thus preserving skin hydration and promoting enhanced smoothness and softness. Within formulations, Copernicia Cerifera Wax serves as an effective natural thickening agent, providing desired viscosity and structure. Its high melting point (81-90°C) also significantly contributes to the thermal stability and overall integrity of cosmetic products. Furthermore, it aids in emulsification and binds oils, improving product consistency.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has repeatedly affirmed Copernicia Cerifera Wax as safe for use in cosmetics, with the latest re-review scheduled for 2025. It also holds Generally Recognized As Safe (GRAS) status as a food additive by the FDA. While generally well-tolerated with minimal irritation observed in animal studies, there is one rare documented case of allergic contact cheilitis linked to its use in a lip balm.
