Applicant's summary and conclusion
- Interpretation of results:
- Category 1B (corrosive) based on GHS criteria
- Conclusions:
- Based on the available data, 1,1,3,3-tetramethyl-2-[3-(trimethoxysilyl)propyl]guanidine, is reported to be corrosive to the skin, in a study conducted according to an OECD guideline, but not in compliance with GLP. Applying the criteria of Regulation (EC) No 1272/2008, classification sub-category 1B is applicable because necrosis was observed in 2/3 animals after exposure for 1 hour, and 3/3 animals after exposure for 4 hours.
