Description of key information

The water solubility of Small Vinyl Ester was tested using the flask method according to OECD guideline for Testing of Chemicals: No. 105. and to EU test method A.6. The water solubility of Small Vinyl Ester was determined to 2.4 mg/l at 20°C. 

Key value for chemical safety assessment

Water solubility:
2.4 mg/L
at the temperature of:
20 °C

Additional information

A preliminary test was performed to assess the water solubility of Small Vinyl Ester, showing that 52.6 mg was not fully dissolved in 350 ml of purified water. In the main test 6 samples containing ~100 mg Small Vinyl Ester and 40 ml water were incubated at 30 °C and constant agitation for 24, 48, and 72 hours followed by 24 hours of equilibration at 20 °C. Samples were taken from the water phase, subjected to centrifugation to further separate the aqueous phase, which was then subjected to HPLC analysis for determination of the concentration of Small Vinyl Ester. Analysis of the results from the three duplicate samples indicated that the test was satisfactory.

The water solubility of Small Vinyl Ester was found to be 2.4 mg/l (standard deviation: 0.05 mg/l).
