Qualifier:

according to guideline

Guideline:

OECD Guideline 105 (Water Solubility)

GLP compliance:

no

Type of method:

Water solubility:

> 250 g/L

Temp.:

20 °C

pH:

5.4

Preliminary test:

Aliquot	Weighed sample, g
A	2.46
B	2.03
Sum	4.49

While being added to the water, solutions with increasing viscosity were being formed, resulting in a gel after the addition of 4.49 g of the test item.

With 4.49 g of test item being mixed into 10 g of water, a gel with a total weight of 14.5 g has been formed. This is equivalent to 31% (w/w) of test item in solution/gel.

As the water density will significantly increase with addition of the test item, it can be concluded that water solubility is about 310 g/L, resulting in a gel. Due to the fact that the formation of the gel is a continuous process and no discrete point can be identified at which dissolution in water switches to gelling, the water solubility can be approximated to > 310 g/L.

Conclusions:

Interpretation of results (migrated information): miscible

Description of key information

> 250 g/L at 20 °C, pH = 5.4

Additional information

The water solubility of the substance was determined according to EU Method A.6 and OECD 105 (flask method). Gel formation at concentrations > 310 g/L was observed.
