REACH - Registration, Evaluation, Authorisation and Restriction of Chemicals - Is a regulation of the European Union that aims to ensure the safe use of chemicals, including those used in cosmetic products.
REACH compliance requires that manufacturers, importers and distributors of chemicals in the EU must register their substances with the European Chemicals Agency (ECHA) and provide information on their properties, uses, and potential risks. The regulation also sets restrictions on certain chemicals that are deemed to be hazardous to human health or the environment.
