Specific details on test material used for the study:
Identification: COSMONE
Batch Number: VE00106679
Purity: 91.6 %
Expiry Date: July 10, 2012
Storage Conditions: Keep container tightly closed in a dry and well-ventilated place
Storage Conditions at Harlan Laboratories: At room temperature at about 20 °C
Key result
Surface tension:
61.4 mN/m
Temp.:
20.1 °C
Conc.:
90 vol%
Conclusions:
The surface tension of COSMONE in water (90% of saturation concentration) was determined to be 61.4 mN/m at 20.1 °C.
Based on the criteria as outlined in the EEC Guideline and the results of this study, COSMONE has not to be considered as a surface active substance.
Executive summary:

The surface tension of COSMONE in water (90% of saturation concentration) was determined with a OECD 115 study to be 61.4 mN/m at 20.1°C.

Based on the criteria* as outlined in the EEC Guideline and the results of this study, COSMONE has not to be considered as a surface active substance.

*According to the criteria as mentioned in the directive, substances showing a surface tension, lower than 60 mN/m under the conditions of this method should be regarded as being surface active material.

Description of key information

Surface Tension: 61.4 mN/m at 20.0 ± 0.5 °C in 90% saturated solution, Guideline no. 115, 2011

Based on the criteria as outlined in the EEC Guideline and the results of this study, COSMONE has not to be considered as a surface active substance.

Key value for chemical safety assessment

Surface tension:
61.4
