Reference
Description of key information
In the range 38.0 to 40.0% w/w at 20.0 ± 0.5 °C.
Assuming density = 1.14 g/L (see dossier section 4.4) water solubility = 433.2 g/L
Key value for chemical safety assessment
- Water solubility:
- 433.2 g/L
- at the temperature of:
- 20 °C
Additional information
A water solubility determination was conducted as part of a package of physicochemical testing on Sulfonic acids, C14-18-alkane hydroxy and C12-20-alkapolyene and C14-18-alkene and C12-20-alkene hydroxy, sodium salts (Envigo Research Limited, 2018, Study GT32WD). The study was conducted in compliance with GLP and the water solubility determination was performed according to procedure designed to be compatible with Method A.6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
The water solubility, as determined by visual appraisal using the modified flask method, was found to be in the range 38.0 to 40.0% w/w at 20.0 ± 0.5 °C
