Echa round-up


Benpat, 1,3-dioxolane substance evaluation conclusions available

Echa has published Germany’s substance evaluation conclusion documents for 1,4-benzenediamine, n,n’-mixed phenyl and tolyl derivatives (benpat), and 1,3-dioxolane.

Germany’s Federal Institute for Occupational Safety and Health (Baua) has concluded that there is a need for follow-up regulation action at EU level, and harmonised classification and labelling for both substances.

Benpat is used as an antioxidant and antiozonant in rubber products and tyres and is suspected of being persistent, bioaccumulative and toxic (PBT) or very persistent and very bioaccumulative (vPvB).

1,3-dioxolane is mainly used for the manufacture of polymers, or as part of plastic products as a monomer bound in polymers. It is also used as a co-monomer in the manufacture of polyoxymethylene (POM), and serves as a typical solvent for a range of wide dispersive uses and products. It is suspected of being mutagenic and reprotoxic.

New intentions to harmonise classification and labelling

Sweden has informed Echa of its intention to submit CLH proposals for eight chemicals. The member state will seek harmonised classification as reprotoxic 1B, H360F for the following:

  • 4-isopropylbenzaldehyde;
  • 3-(p-cumenyl)propionaldehyde;
  • 3-p-cumenyl-2-methylpropionaldehyde;
  • 3-(4-tert-butylphenyl)propionaldehyde;
  • methyl 4-tert-butylbenzoate;
  • 4-tert-butylbenzaldehyde; and
  • 4-tert-butyltoluene.

Sweden also plans to submit a proposal for p-cymene as:

  • reprotoxic 1B, H360F;
  • flammable liquid 3, H226;
  • acute toxicity 3, H331;
  • aspiration toxicity 1, H304; and
  • aquatic toxicity chronic 2, H411.

More than 600 chemicals added to REACH Study database

Since September last year, Echa has added 654 new substances to its REACH Study Results database – a collection of non-confidential data submitted to the agency under REACH.

The data contains results from studies related to:

  • physical-chemical properties;
  • environmental fate and pathways; and
  • ecotoxicology and toxicological information.

The current version of the database, active since March 2017, is the sixth edition.

Iceland actively using Echa poison centres portal

Iceland is now accepting poison centre notifications through Echa’s submissions portal. Bulgaria and Slovakia are the only two EU/EEA states that remain unconnected to Echa’s systems. The agency said they are “working through the onboarding procedure”.

Rac, Seac opinions on dechlorane plus restriction proposal

The consolidated opinions of the agency’s committees for risk assessment (Rac) and socio-economic analysis (Seac) on Norway’s restriction proposal for dechlorane plus are now available.

Both committees support the proposed regulatory action on the flame retardant.
