BS 6829 discusses the analysis of surface-active agents. BS 6829-1.6 belongs to the BS 6829 multi-series and discusses the method for the determination of solubility in water.
BS 6829-1.6 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 solubility curve obtained in the case of pure products may possibly allow the Krafft temperature to be determined.
BS 6829-1.6 on analysis of surface-active agents is useful for:
The method described in BS 6829-1.6 is one of the simplest of the methods which can be used for the determination of solubility in water, it is sufficiently accurate and is suitable for several practical uses.
BS 6829-1.6 provides you with a method of establishing the curve representing the solubility of an anionic surface-active agent in water as a function of temperature, and, consequently, allowing evaluation of its solubility at a given temperature.
