Description

Provitamin C is a stable, lipid-soluble derivative of ascorbic acid, widely recognized for its superior skin penetration and antioxidant efficacy. This compound is a critical precursor in the synthesis of active Vitamin C, offering enhanced stability for formulations requiring long shelf life and consistent performance. It is an essential ingredient for manufacturers in the cosmetics, personal care, and nutraceutical industries, where it is valued for its role in promoting collagen synthesis and providing protection against oxidative stress.

Application

• Cosmetic & Skincare Formulations: A key active in anti-aging serums, creams, and lotions for its collagen-boosting and brightening properties.
• Personal Care Products: Incorporated into sunscreens, after-sun care, and general wellness products for antioxidant protection.
• Nutraceuticals & Dietary Supplements: Used as a stable source of Vitamin C in encapsulated supplements and functional food products.
• Pharmaceutical Intermediates: Serves as a precursor in the synthesis of pharmaceutical-grade ascorbic acid and its derivatives.
• Hair Care Solutions: Formulated into shampoos and conditioners to protect hair from environmental damage and improve scalp health.
• Biochemical Research: Utilized as a standard or reagent in studies related to antioxidant mechanisms and dermatological science.
