Stability & Performance Data
A. Thermal & Discoloration Stability Test (90-Day Real-Time Stress Test)
B. pH-Dependent Degradation Curve Data
Formulators often struggle with the narrow pH window required for traditional Vitamin C. Our lipophilic and hydrophilic amphiphilic structure ensures unmatched resilience across a broad pH spectrum.
Optimal pH Range: 4.0 – 6.0 (Perfect for skin-barrier-friendly formulations).
Degradation Rate: Less than 1.5% active ingredient degradation observed over 12 months within the optimal pH scope.
Formulation Benefit: Eliminates the need for aggressive pH adjusters or high-cost airless packaging.
C. Transdermal Penetration: Pure Vitamin C vs. 3-O-Ethyl-L-Ascorbic Acid
Stability means nothing if the active cannot penetrate the stratum corneum. Thanks to the precise ethyl modification on the 3rd carbon position, our molecule passes seamlessly through lipid bilayers.
Skin Absorption Rate: 4.3x higher skin absorption and retention rate than standard L-Ascorbic Acid.
In-Vivo Conversion: Once absorbed into the epidermis, it is efficiently metabolized into free L-ascorbic acid by native enzymes, providing an immediate 80%+ conversion yield to trigger cellular collagen synthesis and tyrosinase inhibition.
Application
- 3-O-Ethyl-L-ascorbic acid, also known by its alternative name ethyl ascorbic acid, is a derivative of vitamin C (ascorbic acid).
- It is water-soluble but exhibits partial oil solubility, enhancing its skin absorption efficiency.
- Brightening the skin/Reducing hyperpigmentation/Evening out skin tone
