Administrative data

Endpoint:
solubility in organic solvents / fat solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:

Materials and methods

Test guideline
Qualifier:
no guideline available
Principles of method if other than guideline:
WP30 is mixed with octanol then shaked 24 hours at 29 °C. The solution is then filtered on 0.45 µm sieve and analysed by HPLC, after 1 hour and 24 hours to get data on solubilization kinetics.
GLP compliance:
no

Results and discussion

Solubility in organic solvents / fat solubility
Medium:
n-octanol
Solubility:
ca. 0.005 mg/L
Temp.:
25 °C
Test substance stable:
yes
Details on results:
Total solubility was 0.0042 mg/L at time 1hour, and 0.0048 mg/L after 24 hours.
The area percentage of the main component peak was 57.2 % after 1 hour and 50.5 % after 24 hours.
The result was calculated as pure triazine.
