Type of information:

experimental study

Adequacy of study:

key study

Study period:

2nd November, 2016

Qualifier:

according to guideline

Guideline:

other: OECD TG 105

Deviations:

Specific details on test material used for the study:

Batch # 7707959

Medium:

n-octanol

Solubility:

> 2 000 g/L

Temp.:

20 °C

Test substance stable:

not determined

Details on results:

For raw data see Table 1

Table 1: Results of solubility test

Experiment	n-octanol (g)	Weighed sample (g)	Result
A	1.64	0.5152	clear liquid
B	1.64	1.5011	clear liquid
C	1.64	4.0100	clear liquid

With 4.01 g of test item being mixed into 1.64 g of n-octanol, a clear liquid with a total weight of 5.65 g has been formed. This is equivalent to 71.0 %w/w of test item in solution or a concentration of 2.0 kg/L.

Conclusions:

The n-octanol solubility of the test item is > 2.0 kg/L, or rather unlimited.

Executive summary:

The solubility of the test item in n-octanol was determined using OECD TG 105 (shake flask method). Increasing amounts of the test item were added to 1.64 g of n-octanol at room temperature and the mixtures shaken and allowed to stand for 24 hours. The mixture was visually checked for any undissolved parts of the sample. The solubilty of the test item at 20 °C was determined to be equivalent to 71.0 %w/w, or a concentration of > 2 kg/L (i.e. unlimited solubility).

Description of key information

The test item is infinitely miscible with n-octanol.

Key value for chemical safety assessment

Solubility in organic solvents at 20°C:

2 000 g/L
