About

A preservative restricted in the EU Annex V due to significant toxicity concerns.

Benzylhemiformal is listed in EU Annex V/55 as a restricted preservative, permitted only up to 0.15% in ready-to-use cosmetics. It carries extensive hazard classifications including H302/H312 (acute toxicity), H315 (skin irritation), H318 (serious eye damage), H317 (skin sensitization), and H319 (eye irritation). Its formaldehyde-releasing mechanism raises additional safety concerns under EU cosmetic regulation 1223/2009.
