- Migrated informationCriteria used for interpretation of results: EU
- Conclusions:
- The median lethal dose (LD50) value for dihydrogen (ethyl)[4-[4-[ethyl(3-sulphonatobenzyl)amino](4-hydroxy-2-sulphonatobenzhydrylidene]cyclohexa-2,5-dien-1-ylidene](3-sulphonatobenzyl)ammonium, disodium salt is estimated to be 5404.28 mg/kg in rats.
- Executive summary:
The median lethal dose (LD50) value for dihydrogen (ethyl)[4-[4-[ethyl(3-sulphonatobenzyl)amino](4-hydroxy-2-sulphonatobenzhydrylidene]cyclohexa-2,5-dien-1-ylidene](3-sulphonatobenzyl)ammonium, disodium salt is estimated to be 5404.28 mg/kg in rats by oral administration. This value indicates that the substance is not likely to be toxic by oral route as per the CLP criteria.
