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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Phototransformation in air
Administrative data
Link to relevant study record(s)
- Endpoint:
- phototransformation in air
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- calculated 2012-03-13
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Accepted calculation method
- Justification for type of information:
- QSAR prediction: migrated from IUCLID 5.6
- Principles of method if other than guideline:
- Empirical Quantitative Structure-Activity Relationship (QSAR)
- Estimation method (if used):
- AOP Computer Program, Vers. 1.92, integrated in U.S. EPA's EPI program Vers. 3.20
- Light source:
- sunlight
- Relative light intensity:
- 1
- Details on test conditions:
- Sensitiser (for indirect photolysis): OH
Sensitiser concentration: 500000 molecule/cm³ - DT50:
- 20 h
- Test condition:
- see above
- Transformation products:
- not specified
- Conclusions:
- The rate constant of the OH radical sensitized indirect photodegradation of 1,3,3-trimethyl-N-(2-methylpropylidene)-5-[(2-methylpropylidene)amino]cyclohexane-methylamine has been calculated using a well established QSAR method (AOP Computer Program, Vers. 1.92) as 19.0388E-12 cm³/(molecule*sec). This corresponds to a half-life of 20 hours at a 24 hour mean OH radical concentration of 500000 molecule/cm³, which is typical of Central Europe.
- Executive summary:
The rate constant of the OH radical sensitized indirect photodegradation of 1,3,3-trimethyl-N-(2-methylpropylidene)-5-[(2-methylpropylidene)amino]cyclohexane-methylamine has been calculated using a well established QSAR method (AOP Computer Program, Vers. 1.92) as 19.0388E-12 cm³/(molecule*sec). This corresponds to a half-life of 20 hours at a 24 hour mean OH radical concentration of 500000 molecule/cm³, which is typical of Central Europe.

This corresponds to a half-life of 20 hours at a 24 hour mean OH radical concentration of 500000 molecule/cm³, which is typical of Central Europe.
Key value for chemical safety assessment
- Half-life in air:
- 20 h
- Degradation rate constant with OH radicals:
- 0 cm³ molecule-1 d-1
Additional information
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.
