While considering sustainability and safety it is important to comply with (environmental) law and standards. This tool checks whether a chemical substance is currently listed as harmful for humans and/or the environment, based on several national and international regulations, including the REACH-criteria for Substances of Very High Concern (art. 57). Please note that if it is currently not listed in one of these regulations, this does not imply it will not be in the future. The tool links to the Dutch substance-database in which hazard criteria and (environmental) standards are made available. It is possible to search by CAS-number or EC-number.
