Cinnamyl Acetate, with CAS number 103-54-8, is an ester that is commonly used in perfumery for its sweet, floral, and slightly spicy aroma reminiscent of cinnamon. It is often employed in fragrance compositions to impart a warm, comforting character, making it suitable for both floral and gourmand accords. Cinnamyl Acetate typically finds its place in the middle to base notes of a formula, where it can enhance the overall complexity and richness of the scent. In addition to its olfactory properties, it is important to note that Cinnamyl Acetate is subject to regulatory scrutiny due to its potential allergenic effects. It is classified under certain IFRA restrictions, which may limit its usage in cosmetic products to ensure consumer safety. Perfumers should be mindful of these regulations when formulating with this ingredient, particularly in products intended for leave-on applications. — AI-generated summary, 2026-09-02.
