About

An allyl ester used as a fragrance compound with moderate acute toxicity, restricted in EU due to skin sensitization potential and classification as a respiratory irritant.

Allyl isoamyloxyacetate (CAS 67634-00-8) is used as a fragrance ingredient providing fruity-green odor notes in cosmetic formulations. EU Regulation 1223/2009 Annex III restricts its use to concentrations below 0.1% as a constituent of substances or mixtures. The compound carries hazard statements H302 (harmful if swallowed), H315 (causes skin irritation), and H332 (harmful if inhaled), indicating concerns about both acute toxicity and respiratory exposure. The allyl ester structure contributes to its moderate toxicity profile.
