PBT assessment
Some information in this page has been claimed confidential.
Administrative data
PBT assessment: overall result
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- PBT status:
- the substance is not PBT / vPvB
- Likely routes of exposure:
Overall conclusion: Based on the assessment described in the subsections above the submission substance is not a PBT / vPvB substance.
The properties of the constituent blocks are summarised in Table 8.1 and the following conclusions are drawn from the analysis:
- There are no constituents of DTO that meet the criteria for CMR category 1 or 2
- None of the constituents meet the PBT/vPvB criteria when considered individually, but the constituents present in block 10 (Abietal block) do, if their total abundance is taken into consideration. Further work is ongoing to assess this constituent block.
- Testing is ongoing as per ECHA communication number CCH-D-2114412576-50-01/F dated July 09, 2018 and this section will be updated once the results of the tests are available.
The overall conclusion is that the substance does not contain constituents that should be considered as SVHC.

[1]The polymeric constituents of DTO are expected to be persistent in the environment; however, these groups of constituents would be expected not to bioaccumulate due to their high molecular weight.
