Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In accordance with column 2 Annex VII of Regulation (EC) No 1907/2006 (REACH), information requirement section 7.6,  this study does not need to be conducted if surface activity is not a desired property of the material. According to article 2 of Regulation (EC) No 648/2004 the test item does not consist of one or more hydrophilic and hydrophobic groups of such nature and size that it is capable of reducing the surface tension.
Literature shows a surface tension of 35.98 mN/m at 20 °C (Grzeskowiak et al 1960, Yaw's Handbook 2010).

Additional information

In reliabale published literature results of Grzeskowiak et al in Jounal of Chemical Society 1960 as well as a published result in Yaw's Handbook 2010 reported the surface tension. Grzeskowiak publshed the surface tension in temperature ranges between 20 °C and 85 °C. The surface tension at 20 °C was reported to 35.98 mN/m in Grzeskowiak and 35.99 dyne/cm in Yaw's Handbook, but no information on the used guideline and water solubility are reported in these literature.
