Description

Cholesteryl Hydroxystearate is a high-purity sterol ester derived from cholesterol and hydroxystearic acid. This compound is valued for its unique amphiphilic properties, acting as a versatile emulsifier, stabilizer, and liquid crystal material in advanced formulations. It is essential for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking to enhance product texture, stability, and delivery.

Application

• Pharmaceutical Excipient: Used as an emulsifying agent and stabilizer in topical creams, ointments, and transdermal drug delivery systems.
• Cosmetic & Personal Care: Functions as a texture enhancer, emollient, and stabilizer in high-end skincare products, lotions, and makeup formulations.
• Liquid Crystal Displays (LCDs): Serves as a key chiral dopant or component in the manufacture of liquid crystal mixtures for display technologies.
• Biomedical Research: Utilized as a standard or reagent in lipidomics research and membrane studies due to its sterol-based structure.
• Nutraceuticals: Employed as a delivery vehicle for fat-soluble vitamins and active ingredients in supplement formulations.
• Lubricants & Greases: Acts as a thickening agent and performance additive in specialty synthetic lubricants.
