Description

N,N'-Dipalmitoyl-L-Cystine is a high-purity, synthetic lipoamino acid derivative, specifically the dipalmitoyl ester of L-cystine. This compound is valued for its role as a key intermediate and functional ingredient in advanced cosmetic and pharmaceutical formulations, where it contributes to skin barrier repair and stabilization. It is primarily sought by R&D and production teams in the personal care, dermatological, and nutraceutical industries for developing high-performance products.

Application

• Cosmetic & Skincare Actives: Used as a skin-identical lipid and moisturizing agent in anti-aging creams, serums, and barrier repair formulations.
• Pharmaceutical Intermediates: Serves as a critical building block in the synthesis of more complex lipoamino acid-based drug candidates and prodrugs.
• Hair Care Products: Incorporated into conditioners and treatments to improve hair strength, shine, and manageability.
• Biomaterial Research: Utilized in the development of novel drug delivery systems, such as lipid nanoparticles and vesicles.
• Nutraceutical Formulations: Potential use as a specialized ingredient in advanced dietary supplements targeting skin health from within.
• Reference Standards: Supplied as a high-purity analytical standard for quality control and research laboratories.
