Application
Ascorbic Acid Glucoside (AA2G) is a stable derivative of Vitamin C, mainly applied in cosmetics and skincare products, with a small amount used in functional foods.
1
Cosmetics & Skincare (Main Application): It inhibits tyrosinase to reduce melanin production, brighten skin tone, fade dark spots, acne marks and post-inflammatory hyperpigmentation. It also scavenges free radicals, resists photoaging, promotes collagen synthesis, improves skin elasticity, refines pores and controls oil, suitable for all skin types including sensitive skin. It is widely added to whitening serums, creams, masks, sunscreens and men's oil-control products.
2
Other Applications: As a stable Vitamin C, it is used in functional drinks, tablets, solid beverages and oral beauty products (such as whitening pills, collagen drinks), with better stability than ordinary Vitamin C.
⭐
Features: More stable than ordinary Vitamin C, non-irritating, good transdermal absorption, non-photosensitive and can be used during the day.

Frequently Asked Questions
Q
What is Ascorbic Acid Glucoside (AA2G)?
Ascorbic Acid Glucoside (AA2G) is a stable glycoside derivative of Vitamin C, in which a glucose molecule is bonded to ascorbic acid. This structure significantly enhances its stability compared to ordinary Vitamin C, making it widely used in cosmetics, skincare, and functional food products.
Q
What is the purity level of this AA2G product?
The assay of this AA2G product is greater than 99.5%, ensuring high purity. Free ascorbic acid and free glucose are each controlled at ≤0.1%, and the product appears as a white to white crystalline powder with no odor.
Q
Is AA2G safe for sensitive skin?
Yes. AA2G is non-irritating and suitable for all skin types, including sensitive skin. Unlike some forms of Vitamin C that can cause redness or sensitivity, AA2G offers gentle yet effective performance with good transdermal absorption and no photosensitive reaction.
Q
Can AA2G be used in daytime skincare formulations?
Yes. AA2G is non-photosensitive, meaning it does not increase the skin's sensitivity to sunlight. It can be safely incorporated into daytime products such as sunscreens, day creams, and serums without the risk of photosensitivity reactions.
Q
What types of products can AA2G be added to?
AA2G is versatile and can be incorporated into a wide range of products including whitening serums, creams, face masks, sunscreens, men's oil-control products, functional drinks, tablets, solid beverages, whitening pills, and collagen drinks.
Q
What are the packaging and storage requirements for AA2G?
AA2G is packaged in 20 kg cartons. It should be stored in a well-ventilated, cool, and dry place to maintain product quality and stability. Proper storage conditions help prevent degradation and ensure the product retains its high purity level throughout its shelf life.
