Description of key information

The water solubility was determined to be <0.64 mg/l at 20°C

Key value for chemical safety assessment

Water solubility:
0.64 mg/L
at the temperature of:
20 °C

Additional information

The water solubility of the tested substance was assessed according to EU Method A6. It was not possible to develop an analytical method for measurement of substance concentrations and no main study was conducted. The water solubility was therefore estimated by visual observations and was determined to be <0.64 mg/l at 20°C.

Based on this read across result the substance is considered to be of very low solubility.

This is further indicated by the results of QSAR estimates for water solubility run on the two substance constituents typically present at the highest concentration. The predictions were run using the specialised predictive software WSKOW, version 1.41 (from the EPI Suite program (v 3.20), developed by the US EPA).

The estimated results are given below:

Substance Constituent

Estimated Water Solubility

N,N'-[1,3-phenylenebis(methylene)]bis(12-hydroxyoctadecanamide) (CAS No. 128554-52-9)

2.35 x 10-10 mg/l

12-hydroxy-N-{3-[(stearoylamino)methyl]benzyl}octadecanamide (CAS No. 1262779-46-3)

3.23 x 10-11 mg/l
