Additional information
PTSI is extremely water-reactive. It will react immediately with moisture to form p-toluenesulfonyl amide (PTSA) and carbon dioxide. Therefore the chemical safety assessment is conducted for the decomposition product PTSA.
Conclusion on classification
PTSI is extremely water-reactive. It will react immediately with moisture to form p-toluenesulfonyl amide (PTSA) and carbon dioxide. For the decomposition product PTSA, three acute aquatic toxicity tests are available. The lowest E(L)C50 in these tests was a 72h-EC50 of 30 mg/l for algae. This could lead to classification according to the DSD (Directive 67/548/EEC) and CLP (Regulation 1272/2008/EC), but only in combination with a long-term hazard.
PTSA is readily biodegradable and has a log Kow of 0.6. Therefore classification for long-term hazards to the environment is not required.
Based on the above, PTSI and PTSA are not classified for environmental hazards according to the DSD (Directive 67/548/EEC) and CLP (Regulation 1272/2008/EC).
