Tetrahexyldecyl Ascorbate — Cosmetic Grade
Pure Actives' Tetrahexyldecyl Ascorbate (THDA) is a stable, oil-soluble ester of Vitamin C at ≥98% purity, engineered to overcome the key limitations of conventional L-Ascorbic Acid in cosmetic formulations. Unlike water-soluble Vitamin C derivatives, THDA is lipophilic and readily penetrates the stratum corneum's lipid-rich environment, enabling superior dermal delivery of bioavailable Vitamin C. Once absorbed, THDA is enzymatically converted to L-Ascorbic Acid within the skin, where it exerts potent antioxidant, melanogenesis-inhibiting, and collagen-stimulating effects. Its exceptional oxidative stability makes it ideal for formulations requiring long shelf life without the discolouration issues associated with unstable Vitamin C forms.
Key Benefits
- Oil-soluble Vitamin C — superior skin penetration through the lipid barrier
- Converts to bioavailable L-Ascorbic Acid within the skin
- Potent antioxidant — neutralizes free radicals and reduces oxidative stress
- Inhibits melanogenesis — brightens skin tone and reduces hyperpigmentation
- Stimulates collagen synthesis — improves firmness and reduces fine lines
- Highly stable — resistant to oxidation, no discolouration in formulation
