Description of key information
The OECD harmonized ring method was applied for the determination of the surface tension of Quaternium-22. The surface tension of a test solution at a concentration of 1 g/L in water and at 20°C was 73.6 mN/m. According to this, the test item is considered not to be surface active.
Key value for chemical safety assessment
- Surface tension:
- 73.6
- in mN/m at 20°C and concentration in mg/L:
- 1
