- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Version / remarks:
- Adopted by the Council on 27th July 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Version / remarks:
- Directive 92/69/EC (1992)
- Deviations:
- no
- Principles of method if other than guideline:
- The water solubility of a substance is specified by the saturation mass concentration of the substance in water at a given temperature. The water solubility is expressed in mass of solute per volume of solution. The flask method is performed at water solubilities above 10-2 g/L.
In the flask method the substance is dissolved in water at a temperature somewhat above the test temperature. When saturation is achieved, the mixture is cooled an kept at the test temperature until equilibrium is reached. Subsequently, the mass concentration of the substance in the aqueous solution, which must not contain any undissolved particles, is determined by a suitible analytical method. - GLP compliance:
- no
- Other quality assurance:
- other: Tests were carried out according to the requirements of EN ISO 9001
- Type of method:
- flask method

- STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Refridgerator 5°C - Key result
- Water solubility:
- 29.9 mg/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- ca. 6.1
- Remarks on result:
- other: an exact pH-value has not been documented
- Remarks:
- Guideline study OECD 105; relative standard deviation: 2.7 %
- Conclusions:
- In a valid guideline study (OECD 105, non-GLP) using the flask method the solubility of n-Hexyl methacrylate in water was determined to be 29.9 mg/L at 20 °C.
- Executive summary:
In a valid guideline study (OECD 105, non-GLP) using the flask method the solubility of n-Hexyl methacrylate in water was determined to be 29.9 mg/L at 20 °C.
Analyses were performed by HPLC-UV using external standards.
The relative standard deviation (repeatability) of the concentrations in all six samples was smaller than 15 % and the three duplicate sets of samples showed no tendency of increasing concentration values. Thus the test was satisfactory.
