- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: EN 746916/1991
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: room temperature, 20 - 24 °C - Surface tension:
- 64.8 - 68.2 mN/m
- Temp.:
- 20 °C
- Conc.:
- 10 g/L
- Conclusions:
- Surface tension of aqueous solution (20 °C) is 64.8 - 68.2 mN/m.
- Executive summary:
The surface tension study was conducted with DMPPA_701-402-5 as per EEC TG A.5 guideline using Wilhelmy plate method. Based on the study results, surface tension of aqueous solution (20 °C) = 64.8 - 68.2 mN/m at c = 10.0 g/l after 15 min.

Description of key information
The surface tension study was conducted with DMPPA_701-402-5 as per EEC TG A.5 guideline using Wilhelmy plate method. Based on the study results, surface tension of aqueous solution (20 °C) = 64.8 - 68.2 mN/m at c = 10.0 g/l after 15 min. Thus, the substance is considered as not surface-active.
Key value for chemical safety assessment
- Surface tension:
- 64.8
