Key result
Surface tension:
29.1 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Remarks on result:
other: mean corrected value
Conclusions:
The mean surface tension of a test item solution at 1 g/L in water and at 20°C was 29.1 mN/m at 20°C.
Executive summary:

The surface tension of the test item (= REACH substance) was determined in a GLP-compliant study performed in accordance with EC A.5 method and OECD Guideline No. 115, using the OECD harmonized ring method. The mean surface tension of a test item solution at a concentration of 1 g/L in water and at 20°C was 29.1 mN/m. According to this, the test item is considered to be surface active.

Description of key information

The surface tension of the test item (= REACH substance) was determined in a GLP-compliant study performed in accordance with EC A.5 method and OECD Guideline No. 115, using the OECD harmonized ring method. The mean surface tension of a test item solution at a concentration of 1 g/L in water and at 20°C was 29.1 mN/m. According to this, the test item is considered to be surface active.

Key value for chemical safety assessment

Surface tension:
29.1
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

The surface tension of the test item was investigated in one GLP-compliant study performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint.
