Administrative data

skin corrosion: 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 skin corrosion (Category 1, 1A, 1B or 1C)
Justification for type of information:
The substance is a strong base.
A measurement was conducted on 15.02.2017 by Institute for Polyurethane Technology GmbH with a pH-electrode. A solution of 100 g/l of the test material was dissolved in water for the measurement. The pH value was determined to be 11.8.
