Applicant's summary and conclusion
- Interpretation of results:
- Category 1A (corrosive) based on GHS criteria
- Conclusions:
- The ability of 1-Diethylaminopropan-2-ol to induce skin corrosion was investigated by using EpiDerm™SCT (EPI-200).
As a result of the skin corrosion test in the 3-minute and 60-minute exposures, the tissue viabilities treated by the test substance were 19.4% and 8.5%, respectively.
Consequently, it was concluded that 1-Diethylaminopropan-2-ol is "Corrosive" (UN GHS Category 1A) under the present test conditions.
