Ascorbyl Glucoside AA2G CAS 129499-78-1 Stable VC Whitening Raw Material Factory Global Export

Section 1: Product Brief

AA2G (Ascorbyl Glucoside) is the most stable and commercially mature vitamin C derivative across the global cosmetics industry.

Ordinary L-Ascorbic acid has obvious drawbacks: easy oxidation, product yellowing, short shelf life and high irritation, which is not suitable for mass foreign trade production and long-term cross-border sales.

Modified by glucose structure, AA2G completely solves all production defects of native VC: high temperature resistance, acid & alkali resistance, anti-oxidation and strong formula compatibility.
After penetrating the skin, it slowly releases active vitamin C to deliver stable whitening effect without pigment rebound or skin irritation. It is the top replacement ingredient for international brands and also widely applied in food and pharmaceutical industries as antioxidant raw material.

Section 3: Core Production Value for Buyers

1. Excellent formula stability to avoid product deterioration and yellowing

Most VC-containing formulas tend to discolor, lose efficacy and have batch differences, which will cause brand return losses and inventory waste.
AA2G keeps stable under normal temperature, light and heat conditions, effectively prevents yellowing of finished cosmetics and greatly extends shelf life, perfectly matching large-scale foreign trade production and long-term cross-border sales.

2. Mild and safe, suitable for full-skin export formulas

AA2G is non-irritating and non-photosensitive, and will not cause redness or skin sensitivity.
It can be added into high-end product lines for sensitive skin, maternal & infant care and medical aesthetic repair, helping buyers expand target customers and raise product premium.

3. Long-term whitening & anti-photoaging effect

It inhibits tyrosinase activity to block melanin formation at source and reduces existing pigment deposition. Besides, it eliminates free radicals induced by UV rays and relieves skin photo damage, serving as an essential raw material for whitening, sun care and after-sun repair products.

Section 4: Why Global Manufacturers Choose AA2G Instead of Ordinary VC

Ordinary VC: Low cost yet unstable, high after-sales risk, poor finished appearance, unavailable for high-end product lines
AA2G: Stable, compliant, safe, mass-producible, export-friendly with high brand value

As a globally recognized compliant whitening additive, AA2G has been stably adopted by international big brands like L’Oréal with mature market acceptance and consumer recognition.
