Glyceryl ascorbate (CAS 1120360-13-5) is a glycerol ester of vitamin C that delivers antioxidant protection and moisture retention in a single ingredient.

Where is Vitamin C Glyceryl Ascorbate used?

• Skincare: antioxidant and humectant supporting brightening and hydration claims without oxidation instability
• Topical serums, moisturizers and emulsions: compatibility with aqueous systems at a broader pH range than ascorbic acid alone
• Oral nutraceutical and supplement formats: bioavailable vitamin C source
• Food and beverage: antioxidant stabilizer where dual functionality is a priority
• It is often selected for label-friendly positioning in competitive consumer markets requiring high stability.

Good to know: Improved stability over standard ascorbic acid; remains effective where plain vitamin C might degrade. Buyers should confirm purity levels and applicable documentation, such as a CoA, for regulated end markets; compliance with quality standards like USP or FCC may be required depending on the region.
