EUPHORBIA CERIFERA CERA.

Valuable CAS 8006-44-8 / ASTRINGENT, EMULSION STABILISING, FILM FORMING, PERFUMING, SKIN CONDITIONING, VISCOSITY CONTROLLING

EUPHORBIA CERIFERA CERA, commonly known as Candelilla wax, is a botanical wax prized for its multifaceted contributions to skin health and product efficacy. It functions as a robust emollient, forming a protective barrier that significantly enhances skin hydration and fortifies its resilience against external stressors, while simultaneously optimizing cosmetic formulations for superior texture.

Science

Mechanism of Action

Candelilla wax operates primarily as an emollient and film-forming agent, depositing a fine, protective layer on the skin's surface. This physical barrier is crucial for minimizing transepidermal water loss, thereby effectively locking in moisture and substantially improving overall skin hydration. Beyond moisture retention, it also acts as a humectant, drawing water to the skin, and possesses calming properties. The ingredient further contributes to product formulation as a viscosity controller and an emulsion stabilizer, and is noted for its potential Vitamin A content, which may support cellular regeneration.

Stability

Euphorbia Cerifera Cera is a hard, brittle wax characterized by a high melting point, typically between 68-73°C, which contributes to the stability, hardness, and heat resistance of cosmetic formulations. It is highly effective in stabilizing emulsions and enhancing the texture of creams and lotions. The wax is generally incorporated into formulations during the cooling-down phase. With a natural pH of 7.0, no known inactivators have been reported, indicating robust stability.
