REACH is the Registration, Evaluation, Authorization, and Restriction of Chemicals. This regulation of the European Union was adopted to improve the protection of human health and the environment from the possible risks posed by chemicals while enhancing the competitiveness of the EU chemicals industry. Companies identify and manage the risks linked to the substances they manufacture and market in the EU to comply with the regulation. They have to demonstrate to ECHA (European Chemicals Agency) how the substance can be safely used, and they must communicate the risk management measures to the users. REACH includes a Candidate List of Substances of Very High Concern (SVHC), a Restricted List, and an Authorization List.
