Description of key information
Water solubility of test substance [8-[(p-aminophenyl)azo]-7-hydroxy-2-naphthyl]trimethylammonium chloride was estimated to be 2281 mg/L
Key value for chemical safety assessment
- Water solubility:
- 2 281 mg/L
- at the temperature of:
- 20 °C
Additional information
On the basis of prediction using Danish QSAR modelling database (2016), Water solubility of test substance [8-[(p-aminophenyl)azo]-7-hydroxy-2-naphthyl]trimethylammonium chloride was estimated to be 2281 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 Brown 16 (2012), a study report by COLIPA mentioned that water solubility of Basic Brown 16 was 3730 mg/L at 20°C.
On the basis of above available value, Basic Brown 16 was water soluble in the range of 2281 to 3730 mg/L at 20°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
