Product Overview

Ascorbic Acid 2-Glucoside (AA2G), also known as Ascorbyl Glucoside, is a stable Vitamin C derivative produced by combining ascorbic acid with glucose. Compared with pure Vitamin C (L-Ascorbic Acid), AA2G provides enhanced stability and improved usability in cosmetic formulations, making it widely applied in brightening and skincare products.

Key Functional Benefits

Glucose-Bonded Vitamin C Derivative: The unique molecular structure of AA2G combines ascorbic acid with glucose through a stable glycosidic bond, allowing gradual release of active Vitamin C during skincare use.

Formulation Compatibility: Maintains stability across a broad pH range of 5.0 to 7.0, suitable for a wide range of skincare formulations, including brightening serums, emulsions, and creams.

Consistent Quality: Strict control of assay, moisture content (≤1.0%), and impurity levels ensures reliable batch-to-batch consistency for cosmetic manufacturers.

Applications

Brightening Skincare
Used in skincare formulations designed to improve the appearance of uneven skin tone and pigmentation concerns.

Anti-Aging Products
Provides antioxidant benefits and supports collagen-related skincare formulations.
