Understanding Coumarin (CAS 91-64-5): Safety, Handling, and Regulatory Aspects
Coumarin (CAS 91-64-5) is a widely used aromatic compound, celebrated for its characteristic sweet scent. While its applications in perfumery and cosmetics are extensive, it's crucial for formulators and purchasers to understand its safety, handling, and regulatory landscape. Knowledge of these aspects ensures responsible and compliant use of this versatile chemical.
From a safety perspective, Coumarin is classified under the Globally Harmonized System (GHS) with hazard statements such as 'Toxic if swallowed' (H301) and 'Harmful to aquatic life with long-lasting effects' (H412). Precautionary statements emphasize thorough washing after handling, avoiding ingestion and environmental release, and seeking immediate medical attention if swallowed. Standard protective measures, including wearing appropriate gloves and eye protection, are recommended during handling.
The regulatory status of Coumarin is particularly noteworthy in the food industry. In many regions, including the US and EU, Coumarin is prohibited from direct addition or use as a human food ingredient due to concerns about potential hepatotoxicity at higher doses. However, it remains permissible in certain fragrance applications and as a precursor in pharmaceutical synthesis, where strict quality controls are in place.
For industrial users, understanding Coumarin's physical properties is also important for safe handling and storage. It typically appears as white crystals and is soluble in alcohol and oils but not in water. Storage should be in tightly closed containers in a cool, dry, well-ventilated place, protected from heat and light, to maintain its quality and stability.
When purchasing Coumarin, buyers should always request and review the Safety Data Sheet (SDS) from the manufacturer. This document provides comprehensive information on hazards, first-aid measures, fire-fighting measures, accidental release measures, handling and storage, exposure controls, and toxicological information. Ensuring your supplier provides up-to-date and compliant SDS is a critical step in responsible chemical management.
For those looking to buy Coumarin, especially from international manufacturers, verifying that they understand and adhere to the relevant safety and regulatory guidelines is paramount. This due diligence helps ensure that your operations remain compliant and your products are safe for their intended use, whether in sophisticated fragrance creations or vital pharmaceutical applications.
