Tocopheryl Acetate
Tocopheryl Acetate is a synthetic, esterified form of Vitamin E, made by combining Tocopherol (the active antioxidant form of Vitamin E) with acetic acid. This modification improves the compound’s stability and resistance to oxidation, making it more suitable for use in cosmetic formulations that require a longer shelf life.
In the skin, Tocopheryl Acetate is converted into active Tocopherol by enzymatic action, allowing it to provide similar antioxidant and skin-conditioning benefits — although this process is less efficient than applying pure Tocopherol directly. It is widely used in moisturisers, sunscreens, after-sun products, anti-aging creams, and lip balms for its **protective, soothing, and barrier-supporting properties**.
Benefits for Skin
- Acts as a precursor to Tocopherol, delivering antioxidant benefits once converted in the skin.
- Helps protect the skin from oxidative stress and environmental damage.
- Supports skin barrier repair and improves moisture retention.
- Soothes dry, flaky, or irritated skin by reinforcing the lipid barrier.
- Used in combination with other antioxidants (e.g., Vitamin C) to improve overall photoprotection.
- Less prone to oxidation than Tocopherol, making it useful in oil-based and emulsified products.
Safety & Toxicology
- Generally recognised as safe for topical use in cosmetic products.
- Typically used in concentrations from 0.5% to 5%, depending on product type.
- Low risk of irritation or sensitisation in most users, although rare allergic reactions have been reported.
- Non-comedogenic in most well-formulated products.
- Requires enzymatic conversion to Tocopherol for full antioxidant activity — not as potent directly.
- Stable in storage; resists oxidation and maintains potency over time in properly packaged formulations.
