Key result
Remarks on result:
other: An assessment was performed based on available information and uses of the substance. According to section 8.6.1.of REACH, testing for short-term repeated-dose toxicity does not need to be conducted if relevant human exposure can be excluded.

no

Applicant's summary and conclusion

Conclusions:
According to section 8.6.1.of Annex VIII of the REACH regulation ((EC) No 1907/2006), testing for short-term repeated-dose toxicity does not need to be conducted if relevant human exposure can be excluded in accordance with Annex XI Section 3. It was concluded that the use of Annex XI to waive the short-term repeated dose toxicity study based on exposure to the substance was appropriate.
Executive summary:

An assessment in accordance with REACH regulation ((EC) No 1907/2006) was performed to consider the prospect to apply Annex XI adaption rules based on exposure to 2-butoxyethylmethacrylate. According to section 8.6.1. of Annex VIII of the REACH regulation ((EC) No 1907/2006), testing for short-term repeated-dose toxicity does not need to be conducted if relevant human exposure can be excluded in accordance with Annex XI Section 3. It was concluded that the use of Annex XI to waive the short-term repeated dose toxicity study based on exposure to the substance was appropriate. Further testing is therefore considered not required.
