Results and discussion
- Results:
- MTHPA was classified as "Sa", danger of sensitization of airways by the German MAK commission (Commission for the investigation of health hazards of chemical compounds in the work area).
Substances classified as "Sa" can cause symptoms of the airways and also of the conjunctiva (substances causing airway sensitization). - Positive control results:
- no details given
- Negative control results:
- no details given
Any other information on results incl. tables
no details given
Applicant's summary and conclusion
- Interpretation of results:
- sensitising
- Conclusions:
- Tetrahydromethylphthalic anhydride (MTHPA) classified as sensitising to the respiratory tract.
- Executive summary:
- Tetrahydromethylphthalic anhydride (MTHPA) was classified as "Sa", danger of sensitization of airways by the German MAK commission (Commission for the investigation of health hazards of chemical compounds in the work area). Substances classified as "Sa" can cause symptoms of the airways and also of the conjunctiva (substances causing airway sensitization).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
