About

Linalyl acetate — the heart of lavender and bergamot. Beautiful scent, but it hydrolyses/oxidises to linalool, an EU-listed fragrance allergen.

Linalyl acetate (CAS 115-95-7) is the acetate ester of linalool, a major constituent of lavender, bergamot, and clary sage essential oils. Widely used as a fragrance ingredient across fine perfumery and functional cosmetics. On hydrolysis and oxidation it releases linalool, which is on the EU list of 26 fragrance allergens requiring label disclosure above threshold. Oxidised linalool/linalyl acetate is a well-documented contact allergen with prevalence in dermatology patch-test panels. RIFM/IFRA set use-level limits. Not banned, but a known sensitizer — formulations should use antioxidants and cap use levels.
