Applicant's summary and conclusion
- Conclusions:
- The surface tension was determined in a GLP guideline study according to OECD 115, EU method A.5 and DIN EN 14370 without deviations on the registered substance itself. Hence, there is no indication given that the results are not reliable.
The surface tension of an aqueous solution of the test item (90 % of the saturation solubility) was determined to be 36.6 mN/m at 20 °C ± 0.5 °C. - Executive summary:
The surface tension of Octadecanoic acid, reaction products with tetraethylenepentamine was determined by means of a ring tensiometer according to OECD 115, EU method A.5 and DIN EN 14370. The surface tension of an aqueous solution of the test item (90 % of the saturation solubility) was determined to be 36.6 mN/m at 20 °C ± 0.5 °C. Surface tension of water was 72.9 mN/m at 20 °C ± 0.4 °C, hence, the substance has to be regarded as surface active substance.
