Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance decomposes
- Justification for type of information:
- According to R7.1.8.4 Adaptation of the standard testing regime, Adaptation possibilities according to column 2 of Annex VII to REACH
In case of rapid hydrolysis the registrant needs to provide evidence in the form of a hydrolysis endpoint study record (study summary) and should consider testing for the hydrolysis products instead, as information on the properties of (environmentally and toxicologically) relevant degradation products are needed for conducting the risk assessment of the substance to be registered.
Being the substance rapidly hydrolyzed we have considered more appropriate fulfilling the data requirement by using the partition coefficient of the hydrolysis products instead of a QSAR on the substance as such since reliability of the calculation method on the UVCB organometallic compound would be questionable.
The following degradation products have been considered in light of the results of Hydrolysis study: ethanol, 2-propanol, 1-butanol and Phosphoric acid, butyl ester. Phosphoric acid, ethyl ester has not been considered as only present in small amount among degradation products, while Titanium is present as inorganic precipatate after hydrolysis and is not relevant for partition coefficient. - Reason / purpose for cross-reference:

Description of key information
According to R7.1.8.4 Adaptation of the standard testing regime, Adaptation possibilities according to column 2 of Annex VII to REACH, in case of rapid hydrolysis the registrant needs to provide evidence in the form of a hydrolysis endpoint study record (study summary) and should consider testing for the hydrolysis products instead, as information on the properties of (environmentally and toxicologically) relevant degradation products are needed for conducting the risk assessment of the substance to be registered.
Being the substance rapidly hydrolyzed we have considered more appropriate fulfilling the data requirement by using the partition coefficient of the hydrolysis products instead of a QSAR on the substance as such since reliability of the calculation method on the UVCB organometallic compound would be questionable.
Overall result is that none of the degradation products show logPow above 1 at a mixmum temperature of 25 °C.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 1
- at the temperature of:
- 25 °C
