Description

Oxidized Beeswax CAS NO 138724-55-7 is a chemically modified derivative of natural beeswax, characterized by its enhanced polarity, emulsifying properties, and compatibility with a wide range of cosmetic and pharmaceutical ingredients. This modification is crucial for formulators seeking to improve the stability, texture, and performance of emulsions and anhydrous systems. It is an essential ingredient for R&D and production teams in the personal care, cosmetics, and pharmaceutical industries, where it acts as a versatile consistency regulator, stabilizer, and emollient.

Application

• Cosmetic & Personal Care Formulations: Used as a key consistency regulator and stabilizer in creams, lotions, lipsticks, and mascaras to provide structure and improve texture.
• Pharmaceutical Ointments & Creams: Serves as a base or stiffening agent in topical preparations, enhancing viscosity and skin-feel.
• Hair Care Products: Imparts conditioning properties and helps control viscosity in styling gels, pomades, and conditioning treatments.
• Color Cosmetics: Acts as a binder and improves pigment dispersion in pressed powders, eyeliners, and other makeup products.
• Anhydrous Systems: Functions as a structuring agent in balms, solid perfumes, and stick formulations to provide the desired hardness and application properties.
• Industrial Polishes & Coatings: Utilized in specialty polishes for leather, wood, or automotive applications to provide gloss and protective films.
