- Remarks on result:
- other: neat test substance tested
- Conclusions:
- The surface tension at 20 °C of MCPP-P 2-EHE was determined to be 32.2 mN/m for the neat test substance and 65.4 mN/m at 90% aqueous saturation, respectively.
- Executive summary:
A study was conducted according to OECD TG 115, Regulation (EC) No 440/2005 Part A, A.5 (1999) to determine the surface tension of the neat substance and an aqueous solution of the test item using the ring method. Therefore, a saturated solution of the test substance in distilled water was prepared at 90% aqueous saturation. The solution and the neat substance were measured at the test temperature (20°C). The surface tension of MCPP-P 2-EHE was determined to be 32.2 mN/m for the neat test substance and 65.4 mN/m at 90% aqueous saturation at 20 °C.
Reference
The measured surface tension of pure water at 20°C was determined to be 71.7 mN/m. The literature at this temperature is 72.75 mN/m, and therefore the calibration factor was determined to be 1.0146.

Additional information
A study was conducted according to OECD TG 115, Regulation (EC) No 440/2005 Part A, A.5 (1999) to determine the surface tension of the neat substance and an aqueous solution of the test item using the ring method [MCPP-P Task Force, 1999]. Therefore, a saturated solution of the test substance in distilled water was prepared at 90% aqueous saturation. The solution and the neat substance were measured at the test temperature (20°C).The surface tension of MCPP-P 2 -EHE was determined to be 32.2 mN/m for the neat test substance and 65.4 mN/m at 90 % aqueous saturationat 20 °C.
