Description

2-Hydroxy-3-(Stearoyloxy)Propyl 5-Oxo-L-Prolinate is a high-purity specialty ester derived from L-proline and stearic acid, designed for advanced formulation applications. This compound matters for its unique combination of a pyrrolidone-based moiety and a long-chain fatty acid ester, offering specific functional properties in personal care and pharmaceutical systems. It is primarily needed by R&D chemists and formulators in the cosmetics, skincare, and topical pharmaceutical industries seeking innovative functional ingredients.

Application

• Cosmetic & Skincare Formulations: Acts as a multifunctional skin-conditioning agent and emollient in creams, lotions, and serums.
• Topical Pharmaceutical Carriers: Utilized as a potential penetration enhancer or a biocompatible carrier for active ingredients in dermatological preparations.
• Hair Care Products: Serves as a conditioning agent in shampoos, conditioners, and hair treatments to improve manageability and shine.
• Anti-aging & Moisturizing Products: Incorporated for its potential skin-barrier supporting and moisturizing properties.
• Lipid-based Delivery Systems: Used in the development of nanoemulsions, liposomes, or other lipid particulate systems for targeted delivery.
• High-Performance Emollients: Provides a non-greasy, substantive feel in sun care and color cosmetic formulations.
