Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Objective of study:
other: information/assumption on toxicokinetics based on toxicological data
Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
There are no experimental toxicokinetic data with 2,2-dimethylpropane-1,3-diyldibenzoate available. The following remarks on toxicokinetics of 2,2-dimethylpropane-1,3-diyldibenzoate are therefore based on the available studies which were compiled in the respective IUCLID database.
These assumptions follow the procedure indicated in chapter R.7c of the ECHA “Guidance on information requirements and chemical safety assessment” (version 3.0, November 2017).
GLP compliance:
no

Test material

Chemical structure
Reference substance name:
2,2-dimethylpropane-1,3-diyl dibenzoate
EC Number:
224-081-9
EC Name:
2,2-dimethylpropane-1,3-diyl dibenzoate
Cas Number:
4196-89-8
Molecular formula:
C19H20O4
IUPAC Name:
3-(benzoyloxy)-2,2-dimethylpropyl benzoate
Specific details on test material used for the study:
2,2-Dimethylpropane-1,3-diyl dibenzoate is a white to yellowish solid with mild odor. Its molecular weight is 312 g/mol. Its melting point is about 46.5°C at 1017 hPa and the boiling point is >300°C at 1004 hPa. 2,2-Dimethylpropane-1,3-diyl dibenzoate is not inhalable, because it is a wax with a low vapor pressure estimated to be < 0.0001 hPa at 25°C. The water solubility is 1.16 mg/l at 20 °C. The octanol-water partition coefficient (log Kow) of 2,2-dimethylpropane-1,3-diyl dibenzoate was determined to be 4.7 at 25°C and pH 7.

Results and discussion

Main ADME resultsopen allclose all
Type:
other: toxicokinetics
Results:
Specific investigations are not available. The available statements refer to physico-chemial and toxicological data.
Type:
absorption
Results:
Absorption via oral, dermal or inhalation route is anticipated to be low.
Type:
distribution
Results:
The available studies on acute and repeated dose toxicity do not provide information on distribution
Type:
metabolism
Results:
No data available. From results of the in vitro genotoxicity tests it can be assumed that DNA reactive metabolites will most propabely not be generated in mammals in the course of hepatic biotransformation.
Type:
excretion
Results:
No data available. In general the major routes of excretion of an organic compound from the systemic circulation are the urine and/or feces.

Applicant's summary and conclusion

Executive summary:

Specific investigations are not available. The available statements refer to physico-chemical and toxicological data. Absorption via oral, dermal or inhalation route is anticipated to be low. The available acute and repeated dose toxicity studies do not provide information on distribution. No metabolites are identified. From results of the in vitro genotoxicity tests it can be assumed that DNA reactive metabolites will most probably not be generated in the course of hepatic transformation. There is no information on excretion. In general the major routes of excretion of an organic compound from systemic circulation are the urine and / or faeces.
