Additional information

The determination of the surface tension of an aqueous solution of FAT 40841/A TE was done in accordance with EU method A.15 The determination of the surface tension was accomplished by means of a tensiometer, using the ring method. The force which was required to withdraw a horizontally suspended ring from the surface of the solution is measured.
