Cis-3-hexenol, with the CAS number 928-96-1, is a synthetic aroma chemical known for its fresh, green, and grassy scent profile. It is often used in perfumery to impart a natural, leafy character reminiscent of freshly cut grass or green fruits. This compound is typically employed in floral, fruity, and green accords, where it can enhance the overall freshness and complexity of a fragrance. In formulations, cis-3-hexenol is usually found in the top or heart notes, contributing to the initial impression of the scent. While it is valued for its olfactory properties, perfumers should be aware of its safety profile. Cis-3-hexenol is not classified as a common allergen, but as with many synthetic aroma chemicals, it is advisable to use it within recommended usage levels to ensure consumer safety. Regulatory guidelines, such as those from IFRA, may apply, and it is important for formulators to stay informed about any restrictions or recommendations regarding its use in cosmetic products. — AI-generated summary, 2026-09-02.
