Ascorbyl glucoside
Description
Ascorbyl glucoside (CAS 129499-78-1), commercially known as AA-2G, is a stable, glycosylated form of vitamin C used across cosmetic, pharmaceutical, and food applications. Unlike free ascorbic acid, it resists oxidative degradation under normal formulation and storage conditions.
The compound releases active vitamin C enzymatically upon skin or biological contact. This stability profile makes it a preferred vitamin C source for formulators who need reliable, long-shelf-life products for various industrial uses.
In skincare formulations, it functions as a brightening and antioxidant active in serums, creams, and toners, where conventional vitamin C would degrade before reaching the consumer. It is highly valued for its performance.
Pharmaceutical manufacturers use it as a stable vitamin C intermediate in oral supplements and nutraceutical blends targeting antioxidant support. It meets rigorous quality standards including USP and Ph.Eur. requirements.
Food and beverage producers incorporate it as a nutrient fortifier in functional products where ascorbic acid stability is a limiting factor. It is often produced to meet FCC and BP specifications for safety.
It also appears in topical pharmaceutical preparations requiring controlled vitamin C delivery without the formulation challenges associated with unstable ascorbate forms. This versatility is key for modern EP and ACS grade applications.
Ascorbyl glucoside is supplied as a white to off-white crystalline powder. Standard commercial concentrations include high-purity grades of 98% and above, with cosmetic-grade and food-grade specifications available for clients.
Bulk quantities are typically offered alongside smaller packaging options suited to R&D and pilot-scale formulation work. This ensures that manufacturers can scale their production from laboratory testing to full commercial distribution.
