- The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 41.3 mN/m. According to this, the test item is considered to be surface active.
- Executive summary:
The purpose of the study was to determine the physico-chemical properties for Phenol, 1,1-dimethylpropyl derivs.
The study was performed to the following guidelines:
European Community (EC), EC no. 440/2008, Part A: Methods for the Determination of Physico-Chemical Properties, Guideline A.5: “Surface Tension”, Official Journal of the European Union no. L142, May 31, 2008.
Organization for Economic Co-operation and Development (OECD), OECD Guidelines for the Testing of Chemicals no. 115: "Surface Tension of Aqueous Solutions", July 27, 1995.
The OECD harmonized ring method was applied for the determination of the surface tension of Phenol, 1,1-dimethylpropyl derivs.
The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 41.3 mN/m. According to this, the test item is considered to be surface active.
