according to guideline
EU Method A.6 (Water Solubility)
GLP compliance:
Type of method:
flask method
Specific details on test material used for the study:
Component of a Polyurethane System
Polyoxypropylene triamine
(39423-51-3) 60-100%
Key result
Water solubility:
562 g/L
20 °C
Details on results:
Preliminary test:
A water solubility of 361.3 g/L was estimated in the preliminary test.

Formal solubility test:
The mean value for the water solubility determined in the formal solubility test using the shake flask method, is 5.62 E+02 g/L. Consequently, the test material is considered very soluble (> 10000 mg/L)
The pH of 12.7 is an average of 12.68, 12.72 and 12.69 as determined in the three flasks.
The water solubility of the substance is 562 g/L at 20 °C (pH 12.7)

Description of key information

The water solubility of the test substance was determined to be 562 g/L at 20°C and pH 12.7 following EU test method A.6 using the flask method (Baker, 2010).

Key value for chemical safety assessment

Water solubility:
562 g/L
at the temperature of:
20 °C
