Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

At 90% of the saturated solution the surface tension of streams in this category is in the range 71.0 mN/m to 72.0 mN/m at 20°C. The streams are not surface active.

Key value for chemical safety assessment

Surface tension:

Additional information

A proprietary study is available from GKA Competence Centre Analytics (2008) for the stream 68477 -39 -4 (surface tension 71.6mN/m at 20ºC (90% saturation concentration)). These studies were in accordance with a standard guideline and are considered reliable for assessment. The data from these studies will be read across to other members of the category.

The surface tension value for the category is 71.6 mN/m and this has been used to complete the 'key value for chemical safety assessment'. The surface tension result was given at 90% saturation and this has been converted to a concentration in mg/L by applying this factor to the water solubility result for this category.
