Ethyl Levulinate (CAS 539-88-8) is a synthetic aroma chemical known for its sweet, fruity, and slightly floral scent profile. It is often used in perfumery to impart a fresh and uplifting character, making it suitable for a variety of fragrance types, including fruity and floral compositions. Ethyl Levulinate can serve as a top or middle note, contributing to the overall brightness and complexity of a formula. In addition to its olfactory properties, it is valued for its ability to enhance the longevity of other fragrance ingredients when used in blends. As with many synthetic aroma chemicals, it is important to consider safety and regulatory aspects when formulating with Ethyl Levulinate. While specific IFRA restrictions may apply, it is generally regarded as safe for use in cosmetic products when used within established guidelines. Perfumers should always refer to the latest safety data and regulatory information to ensure compliance and safe usage in their formulations. — AI-generated summary, 2026-09-02.
