10 february 2014, echa has recommended a new batch of substances for authorization to the european commission.
these 5 kinds of new proposed authorization substances are n,n-dimethylformamide, diazene-1,2-dicarboxamide (c,c'-azodi(formamide)) , aluminosilicate refractory ceramic fibres, zirconia aluminosilicate refractory ceramic fibres, 4-(1,1,3,3-tetramethylbutyl phenol, ethoxylated. the substances were prioritised because they are used in high volumes and have widespread applications which may pose a threat to human health or the environment.
the recommended substances, including examples of their uses in the scope of authorisation, are:
no. | substance name | svhc property | uses in the scope of authorisation (examples) |
1 | n,n-dimethylformamide (dmf) | toxic for reproduction | solvent for synthesis and for production of coatedtextiles and synthetic fibres |
2 | diazene-1,2-dicarboxamide (c,c'-azodi(formamide)) (adca) | equivalent level of concern due to its respiratory sensitising properties | blowing agent in the rubber and plastics industry |
3 | aluminosilicate refractory ceramic fibres (al-rcf) | carcinogenic | insulation for high-temperature industries; ceramic and metal composite reinforcement; electrical and acoustic insulation |
4 | zirconia aluminosilicate refractory ceramic fibres (zr-rcf) | carcinogenic | insulation for high-temperature industries; ceramic and metal composite reinforcement; electrical and acoustic insulation |
5 | 4-(1,1,3,3-tetramethylbutyl)phenol, ethoxylated (4-tert-octylphenol ethoxylates) (4-tert-opneo) | equivalent level of concern due to its degradation to a substance with endocrine disrupting properties | paints and coating products, emulsion polymerisation |
