Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)

Key result
Surface tension:
69.7 mN/m
Temp.:
20.8 °C
Conc.:
1 g/L
Conclusions:
The mean surface tension of test item in water has been determined to be 69.7 mN/m at 20.8 ± 0.5 °C. The test item was considered to be surface-active.
Executive summary:

The surface tension of 90 % saturated solutions of test item in water have been determined to be 69.7 mN/m at 20.0 ± 0.5 °C, using a ring method, designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.  The test item was considered to be not surface-active.

Description of key information

The mean surface tension of test item in water has been determined to be 69.7 mN/m at 20.8 ± 0.5 °C.  The test item was considered to be surface-active.

Key value for chemical safety assessment

Surface tension:
69.7
