Description

L-Ascorbic Acid 2-Sulfate Dipotassium Salt is a stable, water-soluble derivative of Vitamin C (ascorbic acid). This compound is valued for its enhanced stability and bioavailability compared to ascorbic acid, making it a crucial ingredient in advanced formulations. It is primarily sought by manufacturers in the pharmaceutical, nutraceutical, and high-end cosmetic industries for its antioxidant properties and role in collagen synthesis.

Application

• Pharmaceutical Formulations: Used as a stable source of Vitamin C in injectable solutions, tablets, and capsules where standard ascorbic acid is unsuitable due to stability concerns.
• Nutraceuticals & Dietary Supplements: Incorporated into premium supplement blends for improved shelf-life and controlled release of Vitamin C.
• Cosmetics & Skincare: A key active ingredient in anti-aging serums, creams, and lotions for its antioxidant action and to promote skin brightening and collagen production.
• Biochemical Research: Serves as a reagent and standard in enzymatic studies and research related to Vitamin C metabolism and transport.
• Animal Nutrition: Used in specialized feed additives for aquaculture and livestock to boost immune function and reduce stress.
• Cell Culture Media: Employed as a component in certain cell culture and fermentation media formulations.
