About

An aromatic unsaturated ester providing a sweet, floral, honey-like scent; listed on EU Annex III as a fragrance allergen requiring mandatory declaration on cosmetic labels.

Cinnamyl acetate (3-phenyl-2-propen-1-yl acetate) is an unsaturated aromatic ester widely used in perfumery for its sweet, floral, honey-like character reminiscent of jasmine. It is classified as a fragrance allergen under EU Regulation 1223/2009 Annex III, requiring mandatory label declaration above 0.001% in leave-on products. IFRA restricts its concentration due to documented skin sensitization in both human and animal studies, particularly when used at high levels in leave-on products.
