On November 7, 2024, ECHA’s Member State Committee (MSC) has confirmed the addition of triphenyl phosphate to the Candidate List of substances of very high concern (SVHC). The list now contains 242 entries, some of which are groups of chemicals so the overall number of impacted chemicals is higher.
The substance may be placed on the Authorisation List in the future. Companies need to apply for authorisation to continue the uses once they are on that list.
Ttriphenyl phosphate possesses endocrine disrupting properties and is widely used a flame retardant and as a plasticiser.
The entry added to the Candidate List is shown below:
| Substance name | EC No. | CAS No. | Reason for inclusion | Example of use |
| Triphenyl Phosphate | 204-112-2 | 115-86-6 | Endocrine disrupting properties (Article 57(f) - environment) | This substance is used as a flame retardant and plasticiser in polymer formulations, adhesives and sealants. |
Consequences of inclusion on the Candidate List
Once a substance is identified as an SVHC, it is placed on the Candidate List for Authorization. Suppliers of an article containing SVHC in a concentration of more than 0.1% must provide SDS to downstream users. They should also provide safety use instruction to downstream recipient.
EU manufacturers, importers or only representative (OR) of articles shall notify ECHA if their article contains a Canditate List substance within six months from the date of inclusions.
*For a complete summary of obligations under REACH resulting from inclusion in the Candidate List, check out CL's Chempedia on EU REACH
In addition, under the Waste Framework Directive, companies that have products containing more than 0.1% of SVHC are required to submit notifications through ECHA’s substances of concern in products (SCIP) database.
Under the EU Ecolabel Regulation, products that contain SVHCs are ineligible to receive the ecolabel award.
