Materials and methods

Principles of method if other than guideline:
Pendant drop
A syringe was filled with approximately 10 ml of the solution and was attached to the instrument. The solution formed a drop on the tip of the needle.
This drop was examined optically by the software. The surface tension was calculated by the shape of the drop.
The pendant drop method used has been compared to the ring method OECD 115 and gave good correlation
GLP compliance:
no
Type of method:
other: pendant drop, Perstorp A1577
