Materials and methods

Test guideline

Qualifier:

according to guideline

Guideline:

OECD Guideline 105 (Water Solubility)

Difficulties were encountered with regards to the analytical method. The pH and conductivity of the solutions were checked and the solubility was determined by visual inspection (based on loading rate).

GLP compliance:

no

Type of method:

flask method

Any other information on results incl. tables

The results of the test performed with 0.1 g in 100 mL water are summarized in the following table.

Time (hours)	Test item			Blank (0 g test item)
	pH	Conductivity (μS/cm)	Undissolved test item (visual)	pH	Conductivity (μS/cm)
24	6.8	1.6	Yes	6.3	0.3
48	7.1	2.1	Yes
72	7.3	2.4	Yes
96	7.3	2.9	Yes	7	0.4

 

 

The results of the test performed with 0.1 g in 1000 mL water are summarized in the following table.

Time (hours)	Test item			Blank (0 g test item)
	pH	Conductivity (μS/cm)	Undissolved test item (visual)	pH	Conductivity (μS/cm)
24	6.3	0.6	Yes	6.3	0.3
48	6.4	0.6	Yes
72	6.4	0.9	Yes
96	6.8	1.3	Yes	7	0.4

 

The test item was visually undissolved in 1000 mL of water after 96 hours of agitation.

The conductivity and pH increased very slightly. The test item is an ester substance, its hydrolysis could explain these results.

 

Based on the obtained results, the water solubility of the test item can be expected less than 0.1 g / 1000 mL, which is less than 0.01 %, which is less than 100 ppm.
