- Conclusions:
- The surface tension of the test item 15 % peracetic acid at 20 °C is 47.7 mN/m.
- Executive summary:
The surface tension of an aqueous solution containing 15 % of the test item was determined according to OECD guideline no. 115 and EU test method A.5 with the ring method. There were no deviations from the guidelines.

- Executive summary:
The surface tension of an aqueous solution containing 5 % of the test item was determined according to OECD guideline no. 115 and EU test method A.5 with the ring method. There were no deviations from the guidelines.

There were two runs of measurement of ten determinations each. The mean value of the first run is 47.69 mN/m that of the second run 47.76 mN/m.
Surface tension (at 20 °C): 47.7 mN/m

There were two runs of measurement of ten determinations each. The mean value of the first run is 53.25 mN/m that of the second run 54.82 mN/m.
Surface tension (at 20 °C): 54.0 mN/m
Description of key information
Surface tension (Ring method): 54.0 mN/m (5% neat solution), 47.7 mN/m (15% neat solution)
Key value for chemical safety assessment
- Surface tension:
- 47.7
- in mN/m at 20°C and concentration in mg/L:
- 150
Additional information
Surface tension values of 47.7 mN/m and 54.0 mN/m at 20 °C were measured with the ring method for the 15% and 5% products, respectively (Mekelburger, 2007). The lower value is used as key value. This indicates that peracetic acid does not need to be regarded as surface active, because only substances exhibiting a surface tension < 60 mN/m when tested at a concentration of 0.1% are regarded as surface active.
