Description

Coumarin (CAS 91-64-5) is a naturally occurring lactone compound used as a fragrance ingredient and flavoring agent across cosmetics, food, and industrial applications. Its characteristic sweet, hay-like scent makes it a recognized building block in perfumery.

In personal care and cosmetics, it is incorporated into fine fragrances, soaps, and lotions to deliver a warm, powdery base note. Food and beverage manufacturers use it at controlled levels as a flavoring agent in products such as baked goods.

It is also used in confectionery and alcoholic beverages, subject to regional regulatory limits. In printing and packaging, derivatives function as optical brighteners and UV-curable coating components, contributing to surface modification in specialty inks.

The material also serves as an antioxidant stabilizer in certain industrial formulations where oxidative degradation must be controlled. It is supplied as a white to off-white crystalline powder or in needle crystal form for various industrial uses.

Standard commercial grades include food-grade and technical-grade, with purity levels typically ranging from 98% to 99%+ depending on application requirements. This ensures consistent performance across different manufacturing sectors and product lines.

Pharma-aligned specifications conforming to BP or Ph.Eur. standards are available for regulated end uses. These high-purity options meet the rigorous demands of specialized chemical processing and pharmaceutical manufacturing environments.
