25 °C

Additional information

The aqueous solubility of the test substance Hostapur SAS 93 (Lot DEA4MN7946) was determined by visual observation of a series of samples with different concentrations. The solubility was taken as the maximum concentration at which a clear homogeneous solution is obtained.

Surfactants exhibit a complex solubility behaviour because of the formation of micelles and a variety of liquid crystalline phases. These phenomena were not investigated in the present study, but results from previous experiments are given as additional information.
