Materials and methods

Test guideline

Guideline:

other: homemade method described in the external method EM/00408/01 from Competence Center Analytics, BASF SE (chapter 4: visual method)

Principles of method if other than guideline:

The water solubility of substances with an expected high solubility
is normally determined according to the flask method described in
the OECD Guideline for the Testing of Chemicals 105. To apply
this method, the preparation of a saturated solution of test item in
water is required. Since this is not feasible for test items with a
very high or complete solubility, a homemade method described
in the external method EM/00408/01 from Competence Center
Analytics, BASF SE (chapter 4: visual method) was applied to
investigate complete miscibility.

GLP compliance:

yes

Type of method:

flask method
