Cis-3-Hexenyl Acetate, with CAS number 3681-71-8, is a synthetic aroma chemical known for its fresh, green, and fruity character, reminiscent of freshly cut grass and green apples. It is commonly used in perfumery to impart a natural, leafy quality to fragrances, often found in green, floral, and fruity compositions. This ingredient typically sits in the top to middle notes of a formula, contributing to the overall freshness and vibrancy of the scent. In addition to its use in perfumes, cis-3-Hexenyl Acetate is also utilized in personal care products and household fragrances. As with many synthetic aroma chemicals, it is important to consider safety and regulatory aspects; while specific IFRA restrictions may apply, cis-3-Hexenyl Acetate is generally regarded as safe for use in cosmetic formulations when used within recommended limits. However, as with any fragrance ingredient, it is advisable to conduct thorough safety assessments and consider potential allergenic responses in sensitive individuals. — AI-generated summary, 2026-09-02.
