Description of key information

The surface tension of an aqueous preparation (90% saturation) of one stream within this Category is 72.1 mN/m at 20°C, indicating that these streams are not surface active.

Data from are available for one of the streams in this category. The data will be read across to all category members. This study was conducted to a standard guideline and according to GLP and so is considered fully reliable for use as a key study. The key value has been completed using the only available data for streams in this category. 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 stream.

Key value for chemical safety assessment

Surface tension:
72.1
in mN/m at 20°C and concentration in mg/L:
