Key result

Water solubility:

ca. 11 786 mg/L

Conc. based on:

act. ingr.

Incubation duration:

> 24 h

Temp.:

20 °C

pH:

ca. 3.95

Details on results:

The pH value found for N,N‘-Methylene-bis[methacrylamide] was 3.95.
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.
