water solubility

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2011 - 2012

Reliability:

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 105 (Water Solubility)

GLP compliance:

yes (incl. QA statement)

Type of method:

flask method

Key result

Water solubility:

14 g/L

Conc. based on:

test mat. (total fraction)

Incubation duration:

5 h

Temp.:

20 °C

pH:

6.3

Details on results:

The test item is not stable under the chosen conditions (30°C}. Therefore, conditions with shorter agitating times and conditioning times directly at 20oc were chosen.

Reduced timescale:
Approximately 2.5 g of test item and 16 ml of water were stirred at 20°C for 0.5, 1, 2, 3, 4, 5 and 24 hours. Afterwards the mixtures were conditioned without stirring at 20.0°C.

The water solubility was calculated using results from samples 1hrs to 5 hrs.

Description of key information

14 g/L at 20°C, pH 6.3

Key value for chemical safety assessment

Water solubility:

14 g/L

at the temperature of:

20 °C

Additional information

The determination was carried out by flask method according to OECD Guideline 105.

The test item is not stable with the equilibration temperature at 30°C for 24 hours therefore the solubility has been determined by the equilibration at 20°C. The solubility of 14 g/L has been calculated using the results of the samples from 1 to 5 hours.
