OXIDIZED MICROCRYSTALLINE WAX.

Valuable / VISCOSITY CONTROLLING

Oxidized Microcrystalline Wax is a refined wax derivative primarily functioning as a cosmetic excipient to enhance product texture and stability. Its unique oxidation process improves its compatibility with water-based formulations, making it a versatile ingredient for a range of skincare products.

Science

Mechanism of Action

On the skin, this wax forms a subtle occlusive barrier, which effectively minimizes transepidermal water loss (TEWL) by reducing moisture evaporation from the epidermis. This action helps maintain skin hydration, contributing to a softer and smoother epidermal surface. The oxidation process specifically enhances its film-forming abilities and improves its integration into water-based systems.

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded the parent ingredient, Microcrystalline Wax (Cera Microcristallina), is safe for use in cosmetics. Oxidized Microcrystalline Wax is presumed to fall under similar safety considerations assuming appropriate purification. It holds FDA approval for direct and indirect food contact, and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) established a group Acceptable Daily Intake (ADI) of 0-20 mg/kg bw for related waxes, indicating low concern for genotoxicity.
