- Remarks:
- Surface tension mean. determined from five consecutive measurements with a deviation < 0.1 mN/m from the mean.
- Conclusions:
- The surface tension of test item was determined using a Du Noüy ring and following the OECD Guideline 115, "Surface Tension of Aqueous Solutions" (1995). The procedure is considered to be compatible with the ISO 304 (1985) – Surface Active Agents – Determination of surface tension by drawing up liquid films.
The water solubility is unknown, three solutions of 500 ml were prepared at a loading rate of 1 g/L in distilled water.
Their surface tension was then determined from five consecutive measurements with a deviation < 0.1 mN/m from the mean.
The surface tension of test item was determined to be 40.3 mN/m. - Executive summary:
Results of the two determinations do not differ by more than 0.5 mN/m, so the mean value of 40.3 mN/m is retained for final result.

Reference
Calibration and reference substances
The surface tension of the reference substance methanol was measured before the first determination. A surface tension of 22.7 mN/m was registered and complies with the validation criteria of 22.5 +/- 0.2 mN/m.
The surface tension of the reference substance butanol-1 was measured after the second determination. A surface tension of 24.3 mN/m was registered and complies with the validation criteria of 24.3 +/- 0.2 mN/m.
First determination
The temperature was 20.2°C at the beginning of the determination and 20.3°C at the end of the determination.The temperature during the determination did not vary by more than 0.5°C.
The time elapsed between the preparation of the solution and its transfer to the beaker is 3 minutes and 21 seconds.

The five last values do not differ by more than 0.1 mN/m from the mean, so they were used for the calculation of the mean.
By calculating the average of the five last values, the mean value obtained is 40.4 mN/m.
Second determination
The temperature was 20.3°C at the beginning of the determination and 20.4°C at the end of the determination. The temperature during the determination did not vary by more than 0.5°C.
