Ethyl Butyrate, with CAS number 105-54-4, is a synthetic aroma chemical commonly used in perfumery for its fruity and sweet characteristics, reminiscent of pineapple and other tropical fruits. It is often employed in fragrance compositions to impart a fresh, juicy note, making it a popular choice in fruity and gourmand accords. Ethyl Butyrate typically sits in the top or middle notes of a formula, contributing to the overall brightness and liveliness of the scent. In addition to its use in perfumes, it is also found in flavoring applications, further highlighting its versatility. As with many synthetic aroma chemicals, it is important to consider safety and regulatory aspects when formulating with Ethyl Butyrate. While it is generally recognized as safe for use in cosmetics and fragrances, it is advisable to consult the latest IFRA guidelines and safety data sheets to ensure compliance with any applicable restrictions or recommendations. Overall, Ethyl Butyrate is valued for its ability to enhance the olfactory profile of a fragrance, providing a vibrant and appealing fruity nuance. — AI-generated summary, 2026-09-02.
