Main test

 

Six samples were prepared, each of which contained approx. 250 mg of the test item in 10.0 ml

water. The samples were shaken at 30 C for 24, 48 and 72 h, respectively, then equilibrated at 20 ± 0.5 C for at least 24 h and centrifuged at 3000 rpm for 20 min at 20 °C. The concentration of the test item in these clear aqueous phases of the samples was analysed by HPLC.

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.

Conclusions:
Interpretation of results (migrated information): soluble (1000-10000 mg/L)
The water solubility of Allyl methacrylate is reported to be 2200 mg/L at 20°C (determined according to OECD guideline 105, adopted 27 July 1995;
flask method).
Executive summary:

The water solubility of Allyl methacrylate is reported to be 2200 mg/L at 20°C (determined according to OECD guideline 105, adopted 27 July 1995; flask method).
