Applicant's summary and conclusion
- Executive summary:
INDIRECT PHOTOLYSIS in water OH radical induced indirect photolysis of C20/22 ATQ in air can be estimated with US EPA AOPWIN Program estimating low degradation half-lives (C20 homologue 9.7h, C22 homologue 9h). Therefore C20/22 ATQ may also be degraded in water by indirect photolysis if sufficent OH radicals were available.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
