ECHA Releases the Next Round of SVHC Proposals for Consultation

The next 20 SVHC proposals were released today by the ECHA.  Germany, Norway, Austria, Slovakia, France and the ECHA all contributed to this round of proposals.

All the proposed substances except one are being nominated based on CMR concerns; 4-(1,1,3,3-tetramethylbutyl)phenol, (4-tert-Octylphenol) is the only substance being nominated based on the criteria that it is of equivalent concern to CMRs, PBTs or vPvBs as it has endocrine-disrupting properties and potential for serious effects on the environment.

Some of the substances are found in coatings in the aerospace industry as well as in steel and aluminum coatings, some are found in resins and polymers and others are mostly intermediates while the lead azide, diazide, styphnate and dipicrate are all associated with explosives or ammunition.

Should all 20 proposed substances move forward, there will be 73 substances on the SVHC Candidate List before the end of 2011. Upon addition to the Candidate List, products containing these substances in amounts exceeding 0.1% w/w will be required to communicate the identity of the substance and safe handling instructions. There is also the possibility of notification to the ECHA.

The table below lists the 20 proposed additions to the Candidate List and can be found at:http://echa.europa.eu/news/pr/201108/pr_11_20_svhc_consultation_20110829_en.asp

The full proposals can be viewed at:http://echa.europa.eu/consultations/authorisation/svhc/svhc_cons_en.asp

These proposals can be commented upon by interested parties until October 13th, 2011.

Aluminosilicate Refractory Ceramic Fibres (RCF) Art. 57 (a), carcinogenic Refractory ceramic fibres are used for high-temperature insulation, almost exclusively in industrial applications (insulation of industrial furnaces and equipment, equipment for the automotive and aircraft/aerospace industry) and in fire protection (buildings and industrial process equipment).
Zirconia Aluminosilicate Refractory Ceramic Fibres (Zr-RCF) Art. 57 (a), carcinogenic Refractory ceramic fibres are used for high-temperature insulation, almost exclusively in industrial applications (insulation of industrial furnaces and equipment, equipment for the automotive and aircraft/aerospace industry) and in fire protection (buildings and industrial process equipment).
Formaldehyde, oligomeric reaction products with aniline (technical MDA) 500-036-1 25214-70-4 Art. 57 (a), carcinogenic Mainly used for manufacture of other substances. Minor uses are as hardener for epoxy resins, e.g. for the production of rolls, pipes and moulds, and as well for adhesives.
Bis(2-methoxyethyl) phthalate 204-212-6 117-82-8 Art. 57 (c), toxic for reproduction No registration for this phthalate compound has been submitted to ECHA. Hence, the substance seems not to be manufactured in or imported to the EU in quantities above 1 t/y. Main uses in the past were as plasticiser in polymeric materials and paints, lacquers and varnishes, including printing inks.
2-Methoxyaniline; o-Anisidine 201-963-1 90-04-0 Art. 57 (a), carcinogenic Mainly used in the manufacture of dyes for tattooing and coloration of paper, polymers and aluminium foil.
4-(1,1,3,3-tetramethylbutyl)phenol, (4-tert-Octylphenol) 205-426-2 140-66-9 Art. 57 (f), equivalent level of concern Mainly used in the manufacture of polymer preparations and of ethoxylates. Further used as a component in adhesives, coatings, inks and rubber articles.
1,2-Dichloroethane 203-458-1 107-06-2 Art. 57 (a), carcinogenic Mainly used for manufacture of other substances. Minor uses as solvent in the chemical and pharmaceutical industry.
Bis(2-methoxyethyl) ether 203-924-4 111-96-6 Art. 57 (c), toxic for reproduction Used primarily as a reaction solvent or process chemical in a wide variety of applications. Used also as solvent for battery electrolytes, and possibly in other products such as sealants, adhesives, fuels and automotive care products.
Arsenic acid 231-901-9 7778-39-4 Art. 57 (a), carcinogenic Mainly used to remove gas bubbles from ceramic glass melt and for improving adhesion between copper foil and resin in the production of laminated printed circuit boards
Calcium arsenate 231-904-5 7778-44-1 Art. 57 (a), carcinogenic Calcium arsenate is present in complex raw materials imported for manufacture of copper, lead and a range of precious metals. It appears mainly to be used in metallurgical refinement processes to precipitate nickel from molten copper and to manufacture diarsenic trioxide. However, most of the substance seems to be disposed of as waste.
Trilead diarsenate 222-979-5 3687-31-8 Art. 57 (a) & (c), carcinogenic & toxic for reproduction Trilead diarsenate is present in complex raw materials imported for manufacture of copper, lead and a range of precious metals. The trilead diarsenate contained in the raw materials is in the metallurgical refinement process transformed to calcium arsenate and diarsenic trioxide. Whereas most of the calcium arsenate appears to be disposed of as waste the diarsenic trioxide is used further.
N,N-dimethylacetamide (DMAC) 204-826-4 127-19-5 Art. 57 (c), toxic for reproduction Used as solvent, mainly in the manufacture of various substances and in the production of fibres for clothing and other applications.
