Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Principles of method if other than guideline:
- - Principle of test:
The objective is to check that Proteol SAV 50S matches with the following definition of organic surface-active agents:
If mixed with water at 20 °C and at a 0.5 % concentration; after one hour at the same temperature:
-the product is a transparent or translucent liquid or a stable emulsion without separation of the insoluble material
-the surface tension of water is lowered to 4.5E-2 N/m (45 dynes/cm) or less.
- Short description of test conditions:
Measures at 20°C +/- 1°C with a platinium plate on the tensiometer KRUSS K12.
- Parameters analysed / observed:
Measures number: 100
Maximum time: 200 s
The experience stopped automatically when the standard deviation is equal to 0 mN/m. - GLP compliance:
- not specified
- Type of method:
- plate method
- Surface tension:
- >= 23.6 - <= 23.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 5 g/L
- Conclusions:
- PROTEOL SAV 50S at 20°C and at a concentration of 0,5% in water is a transparent liquid and has a surface tension of 23.65 mN/m.
- Executive summary:
PROTEOL SAV 50S at 20°C and at a concentration of 0,5% in water is a transparent liquid and has a surface tension of 23.65 mN/m.
