Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Campbell et al. (1993): Under the conditions of this study, the surface tension of the test material was 4.81 x 10^-2 N/m at 22.8 °C.
Woll (1992): Under the conditions of this study, the surface tension of a 1 g/L aqueous solution of the test material was determined to be 0.0672 N/m at 20 °C.
Key value for chemical safety assessment
- Surface tension:
- 0
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Two studies are available to address this endpoint and both are considered to be key as the data are equally reliable. The studies were assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).
Campbell et al. (1993)
The surface tension of the test material was investigated in accordance with the standardised guidelines OECD 115 and EU method A.5 under GLP conditions.
The Ring Tensiometer method was used with a concentration of test material of 8.67 mg/mL, in HPLC grade water. A White Torsion Balance was calibrated using HPLC grade water at 22.8 °C. After each determination, the ring and vessel were dipped in chromic acid then distilled water and flame dried. The vessel was rinsed in test solution prior to measurement.
Under the conditions of this study, the surface tension of the test material was 4.81 x 10^-2 N/m at 22.8 °C.
Woll (1992)
The surface tension of the test material was investigated in accordance with the standardised guideline EU Method A.5 under GLP conditions using the OECD ring method.
The measurements are relative to the standard value σ (H2O, 20 °C) = 0.07275 N/m. HPLC water was used in the experiments.
The measurements were started 35 or 40 minutes after the solutions had been prepared. Two series of measurements made within the course of the experiments lasting 185 minutes and 30.5 hours respectively showed no change in surface tension over time.
Under the conditions of this study, the surface tension of a 1 g/L aqueous solution of the test material was determined to be 0.0672 N/m at 20 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
