Loddon, UK -- Risk & Policy Analysts (RPA) is requesting that companies which use 2,4-dinitrotoluene (DNT) complete questionnaires on its use.
RPA said 12 May that it has been contracted by ECHA (the European Chemicals Agency) to collect and provide background information on the markets, uses and releases of 2,4-dinitrotoluene -- and lead chromate.
The aim of this exercise is to support priority setting amongst the substances on the candidate list for potential inclusion in Annex XIV of the REACH Regulation, said RPA.
RPA wants companies involved in the manufacture, import and use of 2,4-dinitrotoluene (and lead chromate) to answer questions on their activities by Friday 28 May 2010.
The group said the study will examine the markets, uses and releases of 2,4-dinitrotoluene, both when these relate to the pure substance (see EC and CAS Numbers above), and for technical grade dinitrotoluene (normally a mixture of dinitrotoluene isomers under EC Number: 246-836-1, and CAS Number: 25321-14-6).
ECHA included DNT, a non-isolated intermediate formed during the manufacture of TDI (toluene diisocynate) in its candidate list of Substances of Very High Concern (SVHCs) in January this year. Also in the list is the flame retardant tris (2-chloroethyl) phosphate (TCEP), which has been used in polyurethanes and is used in other polymers.
