What Is 3-O-Ethyl Ascorbic Acid?
Our 3-O-Ethyl Ascorbic Acid Powder is a 99.5% pure, fermentation-derived vitamin C derivative designed for cosmetic formulations. Its ethyl group enhances stability (resists oxidation in pH 3-7) and bioavailability (5x higher skin penetration vs. L-ascorbic acid, J Cosmet Sci, 2023). Produced via low-temperature crystallization and vacuum drying, it retains full vitamin C activity, ideal for brightening serums, anti-aging creams, and sunscreen boosters.
Why Choose Our Ethylated Vitamin C?
- Unmatched Stability: 99.5% purity + ethyl modification resists degradation (only 0.5% loss at 40°C/3 months, vs. 20% loss in L-ascorbic acid).
- Superior Bioavailability: 5x higher stratum corneum penetration (in vitro Franz cell model, Int J Pharm, 2022), hydrolyzed to active vitamin C in the dermis.
- Clean-Label Source: Fermentation-derived (non-animal) + <0.1% residual ethanol, compliant with EU/US clean-label trends.
- Formulation Flexibility: Soluble in water/alcohol, stable in emulsions (pH 3-7), no discoloration (unlike L-ascorbic acid).
Science-Backed Benefits & Mechanisms (Data-Driven & Neutral)
| Benefit | Key Mechanism/Data | Application Link |
|---|---|---|
| Skin Brightening Support | Chelates Cu²⁺ ions, inhibiting tyrosinase by 50% (melanin synthesis, Exp Dermatol, 2023); fades hyperpigmentation at 2% concentration | Brightening serums, spot-correcting gels |
| Collagen Synthesis Aid | Upregulates procollagen type I (↑30% in fibroblasts, J Invest Dermatol, 2022); improves skin elasticity | Anti-wrinkle creams, firming eye creams |
| Sun-Induced Stress Support | Reduces UVB-induced ROS by 60% (keratinocytes, Photochem Photobiol Sci, 2023); soothes post-sun irritation | Sunscreen boosters, after-sun lotions |
| Radiance Enhancement | Neutralizes free radicals (ORAC=9,500 µmol TE/g); synergizes with vitamin E (boosts efficacy by 3x) | Daily moisturizers, makeup primers |
Versatile Applications
- Skincare Serums: Brightening serums (“3-O-ethyl ascorbic acid for skin tone evening"), anti-aging boosters (collagen support).
- Sunscreens: UV filters synergy (“stable vitamin C for sunscreen formulations"), post-sun repair lotions.
- Color Cosmetics: Foundation primers (radiance enhancement), BB creams (multi-benefit support).
