About this ingredient: EU CosIng ingredient registry (via Open Beauty Facts taxonomy) ↗

Antioxidant: Limits oxidation, including deterioration of formulation ingredients. This label alone does not show a clinical antioxidant effect in skin.
Skin conditioning: A broad cosmetic role for maintaining skin condition. It does not identify a particular clinical benefit.

Function definitions: European Commission ingredient function definitions (SCCNFP/0299/00, pages 16 to 20) ↗

Registry functions describe possible formulation roles, not results for a finished product. A dictionary entry is not an approval or a safety assessment.

A closer look

What the research shows

Human exposure research

A three-month study of topical alpha-tocopherol acetate analysed skin and blood from 11 treated participants with actinic keratoses. It detected absorption into skin but did not detect conversion to free alpha-tocopherol.

What this does not tell us

The overall study enrolled 19 people across two treatments; this report focuses on 11. Absorption is not evidence of a cosmetic benefit, and the results do not allow free-tocopherol findings to be assigned to this ester.
