Details on results:

Concentration of the test substance (mg/L)
After 1 day: 62.5, 62.4
After 2 days: 62.7, 62.7
After 3 days: 62.3, 62.4
Mean concentration of the test substance: 62.5 mg/L

Conclusions:

Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
According to the OECD test Guideline no 105, OBSH has a solubility in water of 62.5 mg/L.

Executive summary:

The solubility of OBSH was tested according to OECD Guideline no. 105 using the flask method. The study was performed in compliance with GLP.

Two measurements of the concentrations were performed at day 1, 2 and 3 using HPLC analysis. The mean concentration of OBSH was 62.5 mg/L, hence it is concluded that OBSH is considered to be slightly soluble (0.1-100 mg/L).

Description of key information

The solubility of OBSH was tested according to OECD Guideline no. 105 in compliance with GLP.
Mean concentration of dissolved test substance was determined to be 62.5 mg/L.

Key value for chemical safety assessment

Water solubility:

62.5 mg/L

at the temperature of:

20 °C

Additional information

Based on the water solubility of 62.5 mg/l (obtained by the flask method, OECD Guideline no 105), it can be concluded that the test substance is slightly soluble (0.1-100 mg/L)
