Ethyl Acetoacetate, with CAS number 141-97-9, is a synthetic aroma chemical commonly used in perfumery for its fruity and sweet characteristics. It is often described as having a pear-like or apple-like scent, making it a popular choice for creating fresh and vibrant fragrance compositions. Ethyl Acetoacetate is typically utilized in the top or middle notes of a formula, where its bright and uplifting qualities can enhance the overall olfactory experience. In addition to its use in fruity accords, it can also contribute to floral and gourmand compositions, providing a sweet, creamy backdrop that complements other ingredients. As with many synthetic aroma chemicals, it is important to consider safety and regulatory aspects when formulating with Ethyl Acetoacetate. While it is generally regarded as safe for use in cosmetics and fragrances, perfumers should be aware of any specific IFRA restrictions or guidelines that may apply, as well as potential allergenic properties that could affect sensitive individuals. Overall, Ethyl Acetoacetate is a versatile ingredient that can add a distinctive fruity note to a wide range of fragrance formulations. — AI-generated summary, 2026-09-02.
