Materials and methods

Principles of method if other than guideline:
The bioelimination of the substance was evaluated in a test based on determination of organic carbon (TOC), according to an internal method. Two substance concentrations were tested and the elimination % was evaluated in a 14-day study period.
GLP compliance:
no
Type of study / information:
Determination of organic carbon (TOC)
