Investigation on the experiment of determination of the critical micelle concentration of sodium dodecyl sulfate

As pharmaceutic adjuvants, surfactants, producing marked effects on wetting, emulsifica- tion, solubilization and so on, are widely used in various types of drugs. The critical micelle concen- tration is an important parameter in the nature of surfactants. It is very meaningful to set up the experi- ment of the determination of the critical micelle concentration in pharmacy. This article investigated the experimental conditions and influential factors and debated the feasibility of the experiment which can be comprehensive and designing .
