Description of key information
The water solubility of the substance is determined to be 5 mg/L at 20 °C and pH = 6.1 - 6.3.
Key value for chemical safety assessment
- Water solubility:
- 5 mg/L
- at the temperature of:
- 20 °C
Additional information
A GLP study was conducted (BASF, 09L00334, 2009) according to OECD 105 and Regulation (EC) 440/2008 Part A to determine the water solubility of the test item. A preliminary test was conducted to estimate the water solubility of the test item. Therefore mixtures of the test item were prepared at different concentrations. After shaking or stirring for three days at room temperature the preparation were visually checked. The water solubility was estimated to be below 8 mg/L. Thus the determination according column elution method was chosen for main test. The determination was performed in duplicated. The samples were analysed via headspace gas chromatography with flame ionisation detector. The water solubility was determined to be 4.8 ± 0.7 mg/L at pH 6.1 to 6.4. No observations were made which cause doubt on the validity of the study.
In a non-GLP supporting study (BASF, OG 82-86, 1981) similar to Regulation (EC) 440/2008 Part A, A.8 the water solubility of the test item was determined using the shake flask method. A test item solution 10% (m/m) in water was prepared and stirred for 30 min. After 30 min settling time the aqueous phase was centrifuged. One part of the aqueous phase was mixed with dioxan in a ratio 1:1. The test item concentration was determined by gas chromatography. Two components of the test item were identified. The water solubility of component A was determined to be 60.75 mg/L and of component B 78.5 mg/L at 20 °C.
In conclusion the water solubility, as determined in the GLP and guideline study, was regarded as most reliable and therefore 5 mg/L was chosen as key value for chemical safety assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
