- 90 other: % saturated
Any other information on results incl. tables
Test temperature: 20°C
Solution concentration: 90% saturated (approximately 230 mg/L,
based on the measured water solubility value of 260 mg/L
Solution age: Prepared immediately before measurement
Initial values were obtained as soon as possible after transfer to the measurement vessel.
Overall mean calibration corrected surface tension = 71.0 mN/m
Harkins-Jordan* corrected value = 70.0 mN/m

Applicant's summary and conclusion
- Conclusions:
- The surface tension of a 90% saturated aqueous solution of SPS 5290 Stage 3 was found to be 70.0 mN/m. As the result was greater than 60 mN/m, the test item was not considered to be surface active.
- Executive summary:
The purpose of this study was to evaluate the surface tension of the test item, SPS 5290 Stage 3.
The study was conducted in accordance with accepted principles in order to meet the requirements of REACH Regulation (EU) No 1907/2006 of the European Parliament and of the Council, Commission Regulation (EC) No 440/2008 (as amended) of 30 May 2008 and the OECD Guidelines for Testing of Chemicals.
This study was conducted according to EC Method A.1 and OECD Method 102.
The surface tension of a 90% saturated aqueous solution of SPS 5290 Stage 3 was found to be 70.0 mN/m. As the result was greater than 60 mN/m, the test item was not considered to be surface active.
