Geranyl Propionate, with CAS number 105-90-8, is a synthetic aroma chemical commonly used in perfumery for its fruity and floral characteristics. It is often described as having a sweet, fresh scent reminiscent of geraniums and is valued for its ability to enhance the overall olfactory profile of a fragrance. In formulations, Geranyl Propionate typically serves as a middle or top note, contributing to the brightness and complexity of floral and fruity accords. It is frequently found in compositions that aim to evoke a sense of freshness and vibrancy, making it suitable for a variety of fragrance types, including perfumes, body sprays, and personal care products. As with many synthetic aroma chemicals, it is important to consider safety and regulatory aspects when using Geranyl Propionate. While it is generally regarded as safe for use in cosmetics, it is advisable to adhere to established guidelines and restrictions, such as those set forth by IFRA, to ensure consumer safety and compliance with regulatory standards. — AI-generated summary, 2026-09-02.
