Description

Cholesteryl 2-Ethylhexanoate is a high-purity cholesterol derivative where the hydroxyl group is esterified with 2-ethylhexanoic acid. This modification enhances its lipophilicity and stability, making it a valuable intermediate and functional additive in advanced formulations. It is primarily sought after by manufacturers in the pharmaceutical, cosmetic, and advanced materials sectors for its role in modifying rheological properties and enhancing delivery systems.

Application

• Pharmaceutical Excipient: Used as a component in lipid-based drug delivery systems, including liposomes and solid lipid nanoparticles (SLNs), to improve drug solubility and bioavailability.
• Cosmetic Ingredient: Functions as an emollient and stabilizer in high-end skincare products, creams, and ointments, contributing to texture and skin barrier enhancement.
• Liquid Crystal Research: Serves as a chiral dopant or component in the study and development of thermotropic and lyotropic liquid crystal materials for display technologies.
• Biomimetic Membrane Studies: Employed in laboratory research to create model membrane systems for studying cholesterol interactions and membrane fluidity.
• Lubricant & Grease Additive: Acts as a specialty additive in synthetic lubricants and greases to modify viscosity and improve performance under specific conditions.
