Product Information

Stable Vitamin C Derivative with Excellent Performance

Traditional vitamin C is widely recognized for its antioxidant and brightening properties, but its instability under exposure to oxygen, light, and heat can create challenges during cosmetic production and storage. Oxidation may lead to reduced activity and unwanted color changes, affecting the final product experience.

3-O-Ethyl-Ascorbic Acid is designed to provide improved stability compared with conventional vitamin C ingredients. Its modified molecular structure enhances resistance against oxidation and environmental factors, helping maintain formulation quality throughout the product lifecycle.

The ingredient demonstrates strong stability against light, heat, acid, alkali, salt, and air oxidation. In a 60℃ aqueous environment for six weeks, the retention rate of 3-O-Ethyl-Ascorbic Acid reaches approximately 95.5%, showing excellent ability to preserve active performance.

This superior stability makes it an ideal choice for cosmetic brands developing long-lasting brightening products and antioxidant skincare formulas.

Unique Amphiphilic Structure for Enhanced Skin Compatibility

One of the key advantages of 3-O-Ethyl-Ascorbic Acid is its amphiphilic structure, which combines both hydrophilic and lipophilic properties. This feature allows the ingredient to maintain water solubility while improving oil compatibility through ethyl modification.

The balanced molecular characteristics support better interaction with cosmetic formulations and enhance penetration through the skin barrier. Compared with some traditional vitamin C derivatives, 3-O-Ethyl-Ascorbic Acid provides improved bioavailability and more efficient delivery of skincare benefits.

Its excellent compatibility makes it suitable for various formulations, including lightweight serums, moisturizing creams, repair products, and multifunctional skincare solutions.

Skin Brightening and Antioxidant Benefits of 3-O-Ethyl-Ascorbic Acid

3-O-Ethyl-Ascorbic Acid is widely used in skincare products focused on brightening, antioxidant protection, and skin conditioning. As a stable vitamin C derivative, it helps improve dull-looking skin and supports a more even skin tone while maintaining gentle application characteristics.

The ingredient provides multiple cosmetic benefits:

• Supports brighter and healthier-looking skin

• Helps protect skin from oxidative stress

• Improves overall skin appearance and texture

• Provides gentle conditioning effects

• Enhances the performance of multifunctional skincare formulations

Compared with pure vitamin C, 3-O-Ethyl-Ascorbic Acid offers improved stability and lower irritation potential, making it suitable for a broader range of skincare applications.
