- 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:

- Specific details on test material used for the study:
- Viscous brown liquid
- Key result
- Surface tension:
- 54.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
- Conclusions:
- The OECD harmonized ring method was applied for the determination of the surface tension of EnvaMul 600.
The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20 °C was 54.5 mN/m. According to this, the test item is considered to be surface active. - Executive summary:
The objective of this study was to determine physico-chemical properties for EnvaMul 600.
The Surface tension, determined according to method EC A.5 / OECD 115, was found to be 54.5 mN/m at 20 °C by the harmonized ring method, and thus, the substance is considered surface active.

Description of key information
The surface tension for EnvaMul 600 was determined according to the OECD Guideline 115. Surface Tension of Aqueous Solutions. The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20 °C was 54.5 mN/m. According to this, the test item is considered to be surface active.
Key value for chemical safety assessment
- Surface tension:
- 54.5
