Stable, Bioavailable Vitamin E for Lipid-Membrane Antioxidant Protection
E-Shield™ delivers high-purity Tocopheryl Acetate — the most widely used and thoroughly safety-documented form of Vitamin E in cosmetic formulation. The acetate ester provides dramatically superior oxidative stability vs. free tocopherol while delivering identical in-skin biological activity: upon application, skin esterases cleave the acetate group to release active α-tocopherol, which integrates directly into cell membranes to protect lipids from peroxidation.
A cornerstone of the clinically validated C+E+Ferulic antioxidant triad, E-Shield™ delivers the lipid-phase protection that water-soluble antioxidants cannot.
Why E-Shield™
- Lipid-membrane antioxidant – intercepts lipid peroxyl radicals in cell membranes; protection where Vitamin C cannot reach
- Superior formulation stability – acetate ester resists oxidation during manufacturing and shelf life
- Skin conditioning – improves perceived softness and moisture retention on application
- Synergizes with Vitamin C & Ferulic Acid – delivers 8× photoprotection in the clinically studied triad combination
- Clean & globally compliant – widely available from plant-derived sources; vegan-compatible
Formulation Advantages
E-Shield™ is oil-soluble and miscible with facial oils, silicones, and lipid emulsion phases. Stable across pH 3.0–7.0 and heat-tolerant during standard emulsion processing. Integrates into oil serums, anhydrous formulas, W/O and O/W emulsions. Most impactful when combined with C-Ethyluxe™ and FeraShield™ for the complete antioxidant defense system.
