- Surface tension:
- 26.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: Arithmetic mean was corrected by calibration factor determined via water calibration
- Conclusions:
- The test item Dermosoft decalact has a surface tension of 26.7 mN/m (concentration = 1000 mg/l) if determined according to method A.5 "Surface tension" as decsribed in Commission Regulation (EC) No. 440/2008.
- Executive summary:
The surface tension of the test item was performed according to the principles laid down in Comission Regulation 440/2008, method A.5. As reference substances water and n- hexane were also tested by using an automatic tensiometer with a built-in evaluation units, by which the necessary corrections using Harkins & Jordan method were performed. The test was performed at 20°C.

Description of key information
26.7 mN/m at 20 °C (Method EC A.5, tensiometer)
Key value for chemical safety assessment
- Surface tension:
- 26.7
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The test on surface tension was performed according to method A.5 laid down in EC Regulation 440/2008.
The test was performed according to GLP requirements. No deviations were observed.
The arithmetic mean of three independant measurements corrected by calibration factor obtained from water giving a surface tesnion of the test substance of 26.7 mN/m.
