Key value for chemical safety assessment

Water solubility:
1 370 mg/L

Additional information

On the basis of prediction using Danish QSAR modelling database (2016), Water solubility of test substance 3-[(4-amino-6-bromo-5,8-dihydro-1-hydroxy-8-imino-5-oxo-2-naphtyl)amino]-N,N,N-trimethylanilinium chloride was estimated to be 13740 mg/L. This solubility value indicated that test substance is soluble in water.

In a opinion given by Scientific Committee on Consumer Safety for Basic blue 99 (2012), soluble in water at 60 deg C determined from kow value (Log kow=-0.88). Therefore, Basic blue 99 were found to be water soluble.

On the basis of above available value, Basic blue 99 (CAS no 68123 -13 -7) was soluble in water at 1370 mg/L.
