REACH is the Regulation of the European Union, adopted to improve the protection of human health and the environment from the risks that can be posed by chemicals, while enhancing the competitiveness of the EU chemicals industry.

The Regulation has an impact on most companies across the European Union and places the burden of proof on companies, who must identify and manage the risks linked to the substances they manufacture and place on the EU market. They have to demonstrate to the European Chemicals Agency (ECHA) how the substance on its own or in mixtures can be safely used and communicate the risk management measures to the users.
