Applicant's summary and conclusion

Conclusions:

Read-across to support the registration of 9-Octadecenoic acid (9Z)-, monoester with 1,2,3-propanetriol ester with boric acid using hydrolytic and metabolic breakdown products is considered to be acceptable. None of the data on the hydrolytic and metabolic breakdown products showed these substances to be toxic to development and so 9-Octadecenoic acid (9Z)-, monoester with 1,2,3-propanetriol ester with boric acid is also considered not to be toxic to development.
