Beta-Pinene, with the CAS number 127-91-3, is a synthetic aroma chemical that is characterized by its fresh, pine-like scent. It is commonly used in perfumery to impart a bright, green, and woody note, often associated with coniferous trees. This compound can be found in various fragrance formulations, typically serving as a top note or a middle note, where it contributes to the overall freshness and complexity of the scent. Beta-Pinene is often utilized in compositions that aim to evoke natural landscapes or to enhance the aromatic profile of other ingredients. In terms of safety and regulatory considerations, Beta-Pinene is recognized as a potential allergen and may be subject to specific restrictions under IFRA guidelines. Perfumers should be mindful of its usage levels in formulations to ensure compliance with safety standards and to minimize the risk of allergic reactions in consumers. — AI-generated summary, 2026-09-02.
