surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Experimental Starting Date: 07/05/2015 and Experimental Completion: 07/05/2015

Specific details on test material used for the study:
Data of Test item as supplied by Huntsman Textile Effects.

FAT Number: 20036/G TE Lot. MH – 0033439900.
Appearance: Black powder.

The test item was measured with a 0.25 % (w/w) solution.
Surface tension:
72.042 mN/m
Temp.:
20 °C
Conc.:
0.25 vol%
Conclusions:
The surface tension of FAT 20036/G was determined to be 72.042 mN/m at room temperature 20 °C.
Executive summary:

The surface tension of FAT 20036/G was determined using plate method specified under OECD Guideline No. 115: “Surface Tension of Aqueous Solutions” (1995) and on the EEC Directive 92/69, Part A, methods for the determination of physico-chemical properties, A.5 “Surface Tension”, EEC Publication No. L383, December 1992.

The determination of the surface tension was accomplished by means of a Tensiometer, using the Wilhelmy plate method. In this method, the force which was required to withdraw a horizontally suspended plate from the surface of the solution is measured. Based on the findings of the study, the surface tension of FAT 20036/G was found to be 72.042 mN/m at room temperature ca 20 °C. The variation of specification factor was 0.001286 mN/m.
