Vitasynol® C

Tetrahexyldecyl Ascorbate

Stable and Bioavailable Vitamin C

VitaSynol® C is a stable, oil-soluble Vitamin C ester but has no inherent capabilities as an antioxidant because all hydroxyl groups are esterified. VitaSynol® C is truly a precursor of Vitamin C, the release of which reduces cell damage triggered by UVB and suppresses UV-induced melanogenesis through ROS scavenging.

Key Attributes

VitaSynol® C releases Vitamin C, which helps reduce cell damage and scavenge reactive oxygen species, suppressing UV-induced melanogenesis. Since the release of Vitamin C may take hours before it shows a protective effect, it’s important to include an effective antioxidant like Synoxyl® AZ or Sytenol® A to VitaSynol® C formulations.
