Description

Ascorbate-3-Phosphate is a stabilized, phosphorylated derivative of Vitamin C (L-ascorbic acid), offering superior stability against oxidation and hydrolysis. This enhanced stability makes it a critical ingredient for applications requiring long-term efficacy and shelf life where traditional ascorbic acid would degrade. It is primarily utilized in the pharmaceutical, advanced cosmetic, and high-end nutraceutical industries as a stable source of Vitamin C activity.

Application

• Pharmaceutical Active Ingredient: Used in injectable and topical formulations as a stable source of Vitamin C for wound healing, antioxidant therapy, and collagen synthesis support.
• Advanced Cosmetic & Skincare: A key active in anti-aging serums, creams, and lotions for its stable antioxidant properties, promoting skin brightening and collagen production.
• Nutraceutical & Dietary Supplements: Incorporated into premium supplement formulations, including effervescent tablets and liquid gels, where moisture stability is paramount.
• Cell Culture & Biomedical Research: Serves as a stable nutrient and antioxidant in cell culture media and various biochemical research applications.
• Aquaculture & Animal Feed: Used as a stabilized Vitamin C source in feed for aquatic species and other animals to prevent deficiency and support immune function.
