Description

This International Standard specifies a method of establishing the curve representing the solubility of an anionic surface active agent in water as a function of temperature, and, consequently, of allowing evaluation of its solubility at a given temperature.

The method is applicable both to pure surface active agents and to technical products or formulations of liquid anionic surface active agents, provided that the solutions of these products are optically clear and are not very strongly coloured.

NOTE The determination of solubility may be carried out without restriction in the temperature range from 0 to 90 °C; at temperatures lower than 0 °C, the determination is possible provided that the solution does not freeze.

The solubility curve obtained in the case of pure products may possibly allow the Krafft temperature to be determined.

Applicable to pure anionic surface active agents.
