3-O-Ethyl Ascorbic Acid
3-O-Ethyl Ascorbic Acid (EAA) is a highly stable, non-ionic, etherified derivative of L-Ascorbic Acid (pure Vitamin C). It is distinguished by its exceptional thermal and photo-stability and unique amphiphilic nature (soluble in both water and oil), allowing for superior skin penetration. EAA offers powerful and sustained delivery of Vitamin C benefits, including skin brightening, collagen synthesis, and antioxidant protection, without the irritation or rapid degradation issues of traditional Vitamin C.

1. Product Overview: The Pinnacle of Stable Vitamin C Delivery
Shaanxi Huatai Bio-fine Chemical Co. provides premium-grade 3-O-Ethyl Ascorbic Acid (EAA), the industry’s most advanced and stable Vitamin C derivative. By protecting the C-3 hydroxyl group with an ethyl moiety, EAA achieves a level of thermal and oxidative resilience that pure L-Ascorbic Acid cannot match. This amphiphilic marvel is the signature solution for luxury brands requiring crystal-clear, high-potency serums that deliver rapid, sustained brightening and collagen-boosting efficacy without the instability or acidity of traditional Vitamin C.
Core Features & Primary Benefits:
-
Amphiphilic Dermal Penetration: Its unique dual-solubility allows it to traverse both the lipid-rich barrier and aqueous-rich cellular layers, ensuring deep-tissue delivery.
-
Unrivaled Stability: Remains fully active and colorless in solution for months, providing a reliable shelf life even in complex, large-batch manufacturing.
-
Rapid Bio-Conversion: Once it reaches the target dermal layer, cellular enzymes efficiently cleave the ethyl group to release pure, active L-Ascorbic Acid precisely where it is needed.
