Description

β-Sitosterol Oleate is a plant sterol ester formed from β-sitosterol and oleic acid. This compound is valued for its ability to modify the physical properties and enhance the bioavailability of phytosterols, making them more soluble in lipid-based matrices. It is primarily sought by manufacturers in the nutraceutical, cosmetic, and functional food industries for formulating cholesterol-management products, skin care emollients, and fortified food ingredients. Its application leverages the health benefits of plant sterols in more versatile and stable delivery systems.

Application

• Nutraceutical Formulations: As a key ingredient in dietary supplements designed to support healthy cholesterol levels by inhibiting intestinal absorption of dietary cholesterol.
• Functional Foods & Beverages: Used for fortifying spreads, dairy products, and health drinks to create cholesterol-lowering food products.
• Cosmetics & Personal Care: Acts as a non-comedogenic emollient and stabilizer in creams, lotions, and ointments, providing skin barrier enhancement and moisturization.
• Pharmaceutical Excipients: Serves as a lipid-soluble carrier or matrix for improving the delivery and absorption of active pharmaceutical ingredients (APIs).
• Research & Development: Utilized as a standard or intermediate in biochemical research concerning lipid metabolism and sterol analysis.
• Industrial Applications: Potential use as a bio-based intermediate or additive in specialty chemical synthesis.
