Echa's Risk Assessment Committee (Rac) has adopted Opinions on harmonised classification and labelling (CLH).
They are for:
- dimethyl disulphide, an intermediate with no current entry in Annex VI of the CLP Regulation;
- 2,2-bis(bromomethyl)propane-1,3-diol, an industrial chemical used in polymers, with no current entry. It agreed with Norway's proposal to classify it as a carcinogen category 1B and mutagen 1B;
- bis(a,a-dimethylbenzyl)peroxide. Contrary to Norway's proposal, it backed classification of the substance as suspected of damaging the unborn child (reprotoxic 1B) and to keep the classifications for skin and eye irritation;
- n-(hydroxymethyl)acrylamide (NMA). The Rac agreed with France's proposal to classify as carcinogen category 1B, mutagen 1B; and specific target organ toxicity-repeated exposure (Stot Re);
- glyoxylic acid. The Rac supported Germany's proposal to classify as eye damage 1 and skin sensitiser 1B;
- trimethoxyvinylsilane. The Rac agreed with Sweden's proposal to classify as skin sensitiser 1B;
- tris(2-methoxyethoxy)vinylsilane. It backed Austria's proposal to classify as reprotoxic 1B;
- tetraglyme, an industrial chemical used mainly as a solvent in paints and coatings. The committee agreed with Austria's proposal of reprotoxic 1B; and
- nitric acid. The Rac supported Germany's proposal to classify as: in concentrations above 70% – fatal if inhaled – (acute toxicity 1); at or below concentrations of 70 % – toxic if inhaled – (acute toxiocity 3) with an ATE for inhalation of 2.65mg/L (dust and mist), and additional labelling with EUH071 (corrosive to the respiratory tract).
