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.

PBT assessment: overall result

PBT status:
further information relevant for the PBT assessment is necessary
Justification:

DMC is not classified as carcinogenic (cat 1A or 1B), cell mutagenic (category 1A or 1B) or toxic for reproduction (category 1A, 1B or 2) in accordance with EC No. 1272/2008.  There is evidence of Specific Target Organ Toxicity (repeated exposure) category 2.  This is an indication that DMC has the potential to be classed as toxic.  However there is results available from OECD testing that shows the LC50 and EC50 concentrations are well in excess of the <0.1 mg/L criterion to be classed as toxic.  Based on the actual OECD test result DMC is not T.

With respect to bioaccumulation the estimated Log Kow for DMC is < 4.5 and so is not B and not vB.  In addition the bio accumulation factor for DMC is 3.16 L/Kg (experimentally determined or estimated by valid EPI suit) below the > 2000 L/kg threshold for BCF.

Therefore the overall conclusion is that DMC is not PBT.

Likely routes of exposure:

The substance is not classified as PBT therefore there route of exposure is not relevant.
