Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The study to determine surface tension does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted; The substance is a symetric diiodide with limited polarity due to symetric structure. Surface activity is not a desired property of the material. In one published literature found, surface tension has been measured at different temperatures and was reported as γ20: 47.86 mN/m; γ40: 45.50 mN/m; γ60: 43.10 mN/m; γ85: 40.10 mN/m, but no concentration was given. As 1,3-diiodopropane is insoluble in water, it is assumed that staurated solutions were measured.
