- Specific details on test material used for the study:
- Test item 207569/B
Identification Quaternium-26
Appearance Clear amber to dark amber liquid
Batch 0001954899
Composition UVCB
Purity ca. 60% in propylene glycol
Storage At room temperature
Stable under storage conditions until 22 December 2017 (retest date) - Key result
- Surface tension:
- 36.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The OECD harmonized ring method was applied for the determination of the surface tension of Quaternium-26. The surface tension of a test solution at a concentration of 1 g/L in water and at 20°C was
36.5 mN/m. According to this, the test item is considered to be surface active.
