Vitamin C Ethyl Ether (Ethyl Ascorbic Acid) is a highly stable and skin-permeable derivative of Vitamin C. Possessing both hydrophilic and lipophilic properties, it serves as a core ingredient for whitening, anti-aging, and antioxidant cosmetics, effectively solving the pain points of traditional Vitamin C, namely its susceptibility to oxidation and poor absorption.
Core Product Advantages
🛡️
1. Exceptional Stability
The ethyl modification at the C3 hydroxyl group completely solves the issues of oxidation, yellowing, and inactivation common in pure Vitamin C. It offers strong formulation compatibility and a long shelf life.
💧
2. Efficient Transdermal Absorption
Its amphiphilic structure adapts well to the skin barrier, providing superior penetration compared to most Vitamin C derivatives and allowing it to reach the dermis to take effect.
🌿
3. Gentle & Low Irritation
Free from the acidic irritation of pure Vitamin C, it is suitable for sensitive skin and does not stain the stratum corneum.
✨
4. Comprehensive Efficacy
Delivers multiple benefits, including whitening, anti-aging, antioxidant, anti-inflammatory, and collagen-boosting effects.
Major Efficacy & Applications
1. Core Efficacy
- Whitening & Spot Fading: Inhibits tyrosinase activity, blocks melanin production, reduces existing melanin, and fades dark spots and acne marks.
- Anti-aging & Firming: Promotes collagen synthesis, increases skin elasticity, and improves fine lines and sagging.
- Antioxidant: Scavenges free radicals, protects against photo-aging and blue light damage, and brightens skin tone to improve dullness.
- Anti-inflammatory & Soothing: Inhibits solar inflammation, soothes redness, and assists in barrier repair.
2. Application Areas (Cosmetics)
- Product Types: Serums, lotions, creams, gels, masks, and toners.
- Formulation Categories: Suitable for all types of formulations focused on whitening, anti-aging, repair, brightening, and antioxidant benefits.

Frequently Asked Questions
QWhat is Vitamin C Ethyl Ether (Ethyl Ascorbic Acid)?
Vitamin C Ethyl Ether, also known as Ethyl Ascorbic Acid (3-O-Ethyl Ascorbic Acid), is a stable derivative of Vitamin C in which the C3 hydroxyl group is modified with an ethyl group. This modification makes it resistant to oxidation while retaining the full biological activity of Vitamin C for skin brightening, anti-aging, and antioxidant benefits.
QHow does Ethyl Ascorbic Acid differ from regular Vitamin C?
Unlike pure Vitamin C (L-Ascorbic Acid), Ethyl Ascorbic Acid is highly stable and does not oxidize or turn yellow upon exposure to air or light. It also has an amphiphilic structure (both water-soluble and oil-soluble), which allows it to penetrate the skin barrier more effectively and reach the dermis, where it can exert its whitening and anti-aging effects.
QWhat is the recommended usage concentration in cosmetic formulations?
The recommended dosage of Ethyl Ascorbic Acid in cosmetic formulations is 0.5% to 2.0%. This range is effective for achieving whitening, antioxidant, and anti-aging benefits while remaining gentle and non-irritating to the skin.
QIs Ethyl Ascorbic Acid suitable for sensitive skin?
Yes. Ethyl Ascorbic Acid is free from the acidic irritation associated with pure Vitamin C. It does not lower the skin's pH significantly, making it well-tolerated by sensitive skin types. It also does not stain the stratum corneum, which is a common concern with some Vitamin C derivatives.
QWhat types of cosmetic products can Ethyl Ascorbic Acid be used in?
Ethyl Ascorbic Acid is versatile and can be incorporated into a wide range of cosmetic products, including serums, lotions, creams, gels, facial masks, and toners. It is compatible with formulations targeting whitening, anti-aging, brightening, repair, and antioxidant benefits.
QHow should Ethyl Ascorbic Acid be stored to maintain its quality?
Ethyl Ascorbic Acid should be stored in a cool, dry, and dark environment. Refrigeration at 2–8 ℃ is preferred to maximize shelf life and preserve its stability. It is packaged in 1 kg aluminum foil bags or 25 kg cardboard drums to protect it from moisture and light during storage and transport.
