Specific details on test material used for the study:
Batch: CVR 83297
Purity/Composition: 97.2%
Test item storage: At room temperature protected from light
Stable under storage conditions until: 27 December 2018 (expiry date)
Key result
Surface tension:
58.8 mN/m
Temp.:
20 °C
Conc.:
90 vol%
Conclusions:
The OECD harmonized ring method was applied for the determination of the surface tension of Epoxypropyl neodecanoate, oligomeric reaction products with cyclohexane-1,2-dicarboxylic anhydride and propylidenetrimethanol. The surface tension of a test solution at 90% of the test item saturation solubility in water and 20 °C was 58.8 mN/m. Thus, the test item is considered to be surface active.
Executive summary:

The OECD harmonized ring method was applied for the determination of the surface tension of Epoxypropyl neodecanoate, oligomeric reaction products with cyclohexane-1,2-dicarboxylic anhydride and propylidenetrimethanol in accordance with OECD Guideline 115 and EC Method A.5. The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20 °C was 58.8 mN/m. Thus, the test item is considered to be surface active.
