REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals) is a regulation of the European Union that regulates chemical substance management. REACH aims to ensure that chemical substances are produced, used and placed on the market without harming human health and the environment. Under this regulation, chemical manufacturers, importers and suppliers are required to register certain chemical substances. During the registration process, comprehensive analyses are performed to determine the properties of chemicals and ensure their safe use.
