New Chemical in Polymers and Textiles Under Scrutiny

In European harmonised classification and labelling news along the lines of CLP classification, the EU Committee for Risk Assessment RAC has adopted opinions on two proposals. 

Two chemical-substances in question

HBCDD, or hexabromocyclododecane is the first.

RAC agreed with the proposal from Sweden to classify HBCDD for reproductive toxicity due to effects on the unborn or breast-fed child.  The main downstream uses of HBCDD are in the polymer and textile industries.  HBCDD can be used on its own or in combination with other flame retardants.  The classification of HBCDD is not harmonised, to use the European spelling, now at the EU level, although various member states have approached classification of the substance.

Leucomalachite green is the second.

RAC also agreed with a proposal from the U.K. to classify leucomalachite green as a carcinogen and mutagen. Leucomalachite green is used as a cell stain in laboratories (histopathology stain).  The classification of this substance is not currently harmonised at the EU level.

Details of the new opinions are expected to be posted at this link, "in the near future," according to ECHA:  http://echa.europa.eu/about/organisation/committees/rac/committee_opinions_en.asp

Who is RAC?

RAC is the group responsible for providing scientific opinions for ECHA on proposals for chemicals' harmonised classification and labelling, also known as CLP or just C&L. The final decision for harmonised classification and labelling is made by the European Commission, by committee.  RAC falls under the risk assessment arm of Chemicals Management in the EU.
