Description of key information

The surface tension of a 90 % saturated aqueous solution of decan-1,2-diol was determined to be 23.33 mN/m (standard deviation ± 0.01) at 20 ºC. As the surface tension is < 60 mN/m, the test item is classified as a surface-active substance. 

Key value for chemical safety assessment

Additional information

The surface tension was determined using the harmonised ring method according to OECD guideline 115 (Thieu-Simchen 2015). The study is considered reliable and relevant for use for this endpoint.
