Administrative data

Endpoint:
eye irritation: in vitro / ex vivo
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a strong acid (pH <= 2.0) or base (pH => 11.5) and the available information indicates that it should be classified as serious eye damage (Category 1)
Cross-reference
Reason / purpose for cross-reference:
reference to other study
Reference
Endpoint:
pH
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2020
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Reason / purpose for cross-reference:
reference to same study
Reason / purpose for cross-reference:
reference to same study
Reason / purpose for cross-reference:
reference to same study
Principles of method if other than guideline:
Measuring with an pH-electrode. For details refer to below sections.
GLP compliance:
no
pH value:
12.5
Concentration:
50 vol%

The pH value of the material was measured to be 12.5.

Conclusions:
The pH value of the material was measured to be 12.5
Executive summary:

In an in-house study, the pH value of the test substance was determined with an pH-electrode. The test item has a pH value of 12.5 in deionized water.
