Results of detailed PBT / vPvB assessment

Persistence

Evidence of non-P / non-vP properties

Screening criteria

Criteria based on Annex XIII of REACH

Conclusion

Conclusion on P / vP properties:

vP (and P)

Remark:

Due to the degradation (29% in 28 d) the substance is classified as not readily biodegradable. The classification for "not ultimately biodegradale within 28 days" is met

Bioaccumulation

Evidence of non-B / non-vB properties

Screening criteria

Not B and not vB based on: Log Kow ≤ 4.5

Remark:

The log POW of the substance is < 0.3

Criteria based on Annex XIII of REACH

Conclusion

Conclusion on B / vB properties:

not B/vB

Toxicity

Evidence of non-T properties

Criteria based on Annex XIII of REACH

Not T based on:

EC10 or NOEC ≥ 0.01 mg/L for marine / freshwater organisms (long-term toxicity):

the values are above this threshold

and substance is not classified as carcinogenic (category 1 or 2), mutagenic (category 1 or 2), or toxic for reproduction (category 1, 2 or 3) according to Directive 67/548/EEC or carcinogenic (category 1A or 1B), germ cell mutagenic (category 1A or 1B), or toxic for reproduction (category 1A, 1B or 2) according to Regulation EC No 1272/2008:

this does not apply

and no other evidence of chronic toxicity, as identified by the classifications T, R48 or Xn, R48 according to Directive 67/548/EEC or specific target organ toxicity after repeated exposure (STOT RE category 1 or 2) according to Regulation EC No 1272/2008:

this does not apply

Evidence of T properties

Conclusion

Conclusion on T properties:

not T
