Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Applicant's summary and conclusion

Executive summary:

INDIRECT PHOTOLYSIS in soil  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 be degraded on soil surface by indirect photolysis but as C20/22 ATQ is rapildly biodegraded in aerobic soils (see IUCLID Section 5.2.3) indirect photolysis will play a minor role in degradation.
