Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2 December 2003

guideline study
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
GLP compliance:

Specific details on test material used for the study:
- Lot/batch No.: 00410155
- Analytical purity: 96%
- Expiration date of the lot/batch: 2004-05-05
- Storage condition of test material: At room temperature at about 20°C
Key result
Surface tension:
69.9 mN/m
Temp.:
21 °C
Remarks on result:
other: 90% saturation concentration

Calibration:

The measured value of the surface tension of water: 70.5 mN/m

Surface tension of water at the test temperature: 72.750 mN/m

Calibration factor is: 72.750/70.5 = 1.0319

The calibration factor was determined by measuring the surface tension of water and comparing with the value available in the laboratory instrument files.

The corrected value was taken from a table compiled on the basis of the Harkins-Jordan correction.
Conclusions:
The surface tension of T002251 in water (90% of saturation concentration) was determined to be 69.9 mN/m at 21°C. Based on the criteria as outlined in the EEC Guideline, T002251 is not a surface active substance.

Description of key information

The surface tension of T002251 was assessed in a GLP study (K1, Tognucci, 2004) according to the OECD guideline 115 and EU method A.5. The surface tension in water at 90% of saturation concentration was determined to be 69.9 mN/m at 21°C. Based on the criteria as outlined in the EEC Guideline, T002251 is not a surface active substance.

Key value for chemical safety assessment

Surface tension:
69.9
