Delta-Nonalactone, with CAS number 3301-94-8, is a synthetic aroma chemical known for its creamy, coconut-like scent profile. It is often used in perfumery to impart a smooth, milky character to compositions, making it a popular choice in gourmand and floral fragrances. Delta-Nonalactone typically sits in the base or heart of a formula, where it can enhance the overall richness and depth of the scent. Its unique olfactory properties allow it to blend well with other ingredients, particularly those that are fruity or sweet, contributing to a well-rounded fragrance experience. While delta-Nonalactone is generally considered safe for use in cosmetics, it is important for formulators to be aware of any potential regulatory restrictions or allergen declarations associated with its use. As with many synthetic aroma chemicals, it is advisable to consult the latest IFRA guidelines to ensure compliance with safety standards in fragrance formulations. — AI-generated summary, 2026-09-02.
