EC number: 949-694-5
CAS number: -
Agitation period (days)
Measured silicon content of the test solution (mg/L)
Concentration of test item in test solution* (mg/L)
Maximum measured difference (%)
*The silicon content of the test item was 26.6% so the measured silicon
content of the test solution was multiplied by 3.76 (100/26.6) to
calculate the concentration of test item in test solution.
As the maximum difference in silicon content between test solutions 3, 4
and 5 (a and b) was less than 15% (14.9%), it was judged that the
silicon concentrations of these test solution reached equilibrium and
are therefore valid. Samples 1 and 2 (a and b) are discounted.
The aqueous solubility of the test item was measured in a GLP study
performed using method OECD 105. Aqueous samples, with a 1 g/L loading,
were incubated for 6, 7 and 8 days at 30 °C and silicon content measured
via ICP-AES. As the silicon content of the test item was 26.6%, the
aqueous solubility of the test item was determined to be 1.02 mg/L at 20
