REACH is a 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.


As a major focus of REACH regulation, the candidate list of Substances of Very High Concern (SVHC) has been continuously updated since its entry into force. If an article contains any SVHC (concentration above 0.1%(w/w)) included in the Candidate List, EU manufacturer or importer shall fulfill the obligations of notification and provide sufficient information on request to consumers within 45 days upon the receipt of this request.

Recently, the European Union has added two more substances to the SVHC Candidate List, which are 1,2,4-triellitic anhydride (TMA, CAS No. 552-30-7) and Dicyclohexyl Phthalate (DCHP, CAS No. 84-61-7). DCHP and TMA was previously proposed to be added to the SVHC Candidate List during the 15th and 16th batch of inquiries, but was not included in the final list as no consensus was reached.
