Type of information:
experimental study
Adequacy of study:
weight of evidence
Study period:
2017-04-19
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Reason / purpose:
reference to same study
Qualifier:
according to
Guideline:
OECD Guideline 111 (Hydrolysis as a Function of pH)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method C.7 (Degradation: Abiotic Degradation: Hydrolysis as a Function of pH)
Deviations:
no
GLP compliance:
no
Remarks:
No claim of GLP compliance is made for this study because no experimental work was performed.
Transformation products:
not measured
Remarks on result:
not determinable because of methodological limitations
Remarks on result:
not measured/tested

Determination of hydrolytic stability was not carried out using Method C.7 Abiotic Degradation, Hydrolysis as a Function of pH of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 111 of the OECD Guidelines for Testing of Chemicals, 13 April 2004 as the active ingredient in the test item was an inorganic. The test method is not applicable to inorganic substances. Additionally, the test item as a whole would be too insoluble for the test to be performed practically.

Validity criteria fulfilled:
not applicable
Conclusions:
Determination of hydrolytic stability was not carried out using Method C.7 Abiotic Degradation, Hydrolysis as a Function of pH of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 111 of the OECD Guidelines for Testing of Chemicals, 13 April 2004 as the active ingredient in the test item was an inorganic. The test method is not applicable to inorganic substances. Additionally, the test item as a whole would be too insoluble for the test to be performed practically.
Executive summary:

Determination of hydrolytic stability was not carried out using Method C.7 Abiotic Degradation, Hydrolysis as a Function of pH of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 111 of the OECD Guidelines for Testing of Chemicals, 13 April 2004 as the active ingredient in the test item was an inorganic. The test method is not applicable to inorganic substances. Additionally, the test item as a whole would be too insoluble for the test to be performed practically.

Endpoint:
hydrolysis
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is highly insoluble in water
