Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
ABIOTIC
DEGRADATION IN AIR
DIRECT
PHOTOLYSIS in air
DTDMAC does not absorb light >290 nm (ozone band) and
therefore a direct photolysis in air will not occur.
INDIRECT PHOTOLYSIS in air
OH radical induced indirect photolysis of DTDMAC can be estimated with US EPA AOPWIN Program estimating low degradation half-lives e.g.. 1h for DTDMAC. As the estimated Henry’s Law Constant of 6.5*10-3 Pa*m3/mole (DTDMAC) is low, volatilisation is not an exposure route which has to be considered.
ABIOTIC DEGRADATION IN WATER
HYDROLYSIS
DTDMAC has no functional groups which could be hydrolyzed under environmental conditions pH 4 to 9 as stated in OECD Guideline 111. Therefore it is scientifically unjustified to carry out this study.
DIRECT
PHOTOLYSIS in water
DTDMAC
does not absorb light >290 nm (ozone band) and therefore a direct
photolysis in water will not occur.
INDIRECT PHOTOLYSIS in water
OH radical induced indirect photolysis of DTDMAC in air can be estimated with US EPA AOPWIN Program estimating low degradation half-lives e.g. 1h for DTDAMC. Therefore DTDMAC may also be degraded in water by indirect photolysis if sufficent OH radicals were available.
ABIOTIC DEGRADATION IN SOIL
DIRECT PHOTOLYSIS in soil
DTDMAC does not absorb light >290 nm (ozone band) and therefore a direct photolysis on soil surface will not occur.
INDIRECT PHOTOLYSIS in soil
OH radical induced indirect photolysis of DTDMAC in air can be estimated with US EPA AOPWIN Program estimating low degradation half-lives e.g. 1h for DTDMAC. Therefore DTDMAC may be degraded on soil surface by indirect photolysis.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
