Diethyl Malonate, with CAS number 105-53-3, 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 fruity accords. In fragrance formulations, Diethyl Malonate typically serves as a top note, contributing to the initial impression of a scent. It can also be found in various compositions aimed at evoking a sense of freshness and brightness. While it is generally considered safe for use in cosmetics and fragrances, it is important for formulators to be aware of any regulatory guidelines or restrictions that may apply, particularly in relation to IFRA standards. As with many synthetic aroma chemicals, it is advisable to use Diethyl Malonate within recommended usage levels to ensure consumer safety and compliance with relevant regulations. — AI-generated summary, 2026-09-02.
