Details on results:
Sample concentration of 10 g/L to 500 g/L :
Result of tests : Soluble, with no residue or phase separation, clear and bright solution
Aspect After One Day at 20°C : No residue or phase separation, clear and bright solution.

Sample concentration > 800 g/L :
Result of tests : Hazy homogeneous solution, single phase.
Aspect After One Day at 20°C : Hazy homogeneous solution, single phase.
Conclusions:
The value of water solubility of the test sample has to be considered greater than 500 g/L. The sample is considered freely soluble in water
Executive summary:

In an OECD 105 study, the value of water solubility of the test sample has to be considered greater than 500 g/L. The sample is considered freely soluble in water
