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.
- Recommended Dosage: 0.5% – 2.0%

Frequently Asked Questions
What is Vitamin C Ethyl Ether (Ethyl Ascorbic Acid)?
Vitamin C Ethyl Ether, also known as Ethyl Ascorbic Acid, is a stable derivative of Vitamin C in which an ethyl group is added at the C3 hydroxyl position. This modification gives it both hydrophilic and lipophilic properties, making it highly effective and stable for use in cosmetic formulations.
Why is Ethyl Ascorbic Acid more stable than pure Vitamin C?
The ethyl modification at the C3 hydroxyl group protects the molecule from oxidation, preventing the yellowing and inactivation that commonly occur with pure Vitamin C. This results in a significantly longer shelf life and better formulation compatibility.
Is Ethyl Ascorbic Acid suitable for sensitive skin?
Yes. Unlike pure Vitamin C, Ethyl Ascorbic Acid is free from acidic irritation, making it well-tolerated by sensitive skin types. It also does not stain the stratum corneum, offering a gentle yet effective alternative.
What is the recommended usage dosage in cosmetic formulations?
The recommended dosage of Ethyl Ascorbic Acid in cosmetic formulations is 0.5% to 2.0%. This range is effective across a variety of product types including serums, creams, lotions, masks, gels, and toners.
How should Ethyl Ascorbic Acid be stored?
It should be stored in a cool, dry, and dark environment. Refrigeration at 2–8 ℃ is preferred to maintain its stability and extend its shelf life. It is available in 1 kg aluminum foil bags and 25 kg cardboard drums.
What skin benefits does Ethyl Ascorbic Acid provide?
Ethyl Ascorbic Acid offers comprehensive skin benefits including whitening and spot fading by inhibiting tyrosinase activity, anti-aging and firming by promoting collagen synthesis, antioxidant protection against free radicals and photo-aging, and anti-inflammatory effects that soothe redness and support skin barrier repair.
