OZOKERITE.

Valuable CAS 64742-33-2 / BINDING, EMULSION STABILISING, OPACIFYING, VISCOSITY CONTROLLING

Ozokerite is a natural mineral wax that forms a protective, semi-occlusive barrier on the skin, effectively reducing transepidermal water loss by 20-30% in tested models. This action significantly enhances skin hydration, softens texture, and imparts emollient benefits, contributing to a smooth and refined complexion.

Science

Mechanism of Action

On the skin, Ozokerite creates a thin, protective film that acts as a semi-occlusive barrier. This physical barrier effectively minimizes water evaporation from the skin's surface, thereby enhancing moisture retention and supporting overall skin hydration. Its emollient properties also contribute to a smoother and softer skin texture.

Stability

Ozokerite exhibits exceptional stability, being resistant to water, alkalis, and most acids, with breakdown occurring only with fuming sulfuric or concentrated nitric acids. Its high melting point, typically ranging from 58-100°C, ensures product integrity across a broad range of temperatures. For optimal incorporation, it should be added to the heated oil phase of formulations.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

Both the Cosmetic Ingredient Review (CIR) and the FDA affirm Ozokerite's safety for cosmetic use based on extensive historical data and multiple evaluations since 1984. It is generally well-tolerated and not identified as a common allergen or irritant; purified cosmetic grades have shown no irritation in patch tests at concentrations up to 50%. While animal studies at high dietary intakes indicated some systemic effects, these are not considered relevant to typical topical cosmetic applications.
