ECHA Recommends Authorization for Seven Additional Substances of Very High Concern

The EU wants to include seven additional substances of very high concern (SVHC) in Annex XIV of REACH (Authorization List). As part of the public consultation, active participants and interested parties can comment on the recommendation from March 5 to June 5.

The chemicals involved include:

Siloxane octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6): They are treated as a group because of their similar structure and properties. According to Article 57, d and e of REACH, all of them have persistent, bioaccumulative, and toxic (PBT) properties. They are also considered very persistent and very bioaccumulative (vPvB).

Terphenyl, hydogenated: Is very persistent and very bioaccumulative (vPvB). The chemical is used in heat transfer fluids, adhesives, sealants, coatings, and paints.

Dicyclohexylphthalate (DCHP): Is classified by Article 57 (a-f) of REACH as a substance of high concern. It is reprotoxic and endocrine-disrupting. It is used as a plasticizer for plastics and rubber.

Disodiumoctaborate: Is classified by Article 57 c of REACH as reprotoxic. It is used in building products, adhesives, and paints.

Benzene-1,2,4-tricarboxylic acid 1,2-anhydride (trimellitic anhydride: TMA): Is classified by Article 57 f of REACH as a substance of very high concern (it is endocrine-disrupting, among other properties). The chemical also has respiratory-sensitizing properties.

What’s the procedure? After the comments have been collected, the ECHA’s Member State Committee (MSC) will issue an opinion. In the next step, the ECHA will issue its recommendation. Before the chemicals can appear on the Authorization List, the member states, the EU Commission, and the EU Parliament must approve the change. Users must then apply for authorization for the chemicals on the list.

Right now, the Authorization List contains 54 chemicals.
