About
A small fruity-green fragrance ester used at trace levels to add sweet, apple-like top notes. Typical fragrance caveats apply.
Prenyl acetate (3-methyl-2-butenyl acetate, CAS 1191-16-8) is a small volatile ester with a sweet, fruity, green fragrance used in perfumery at trace levels (typically <0.1% in finished product). Biodegradable, low bioaccumulation. As with most small-molecule fragrance esters, raw material can be irritating to eyes and respiratory system; finished-product exposure is low. No EU Annex II listing. IFRA (fragrance industry) has no use-level restriction. Not on the EU 26-allergens disclosure list, but individual fragrance sensitivity is always possible. Prior score of 100 was unjustified — corrected to standard fragrance profile.
