WebDetergents are also known as surfactants as they have the ability to decrease the surface tension of water. Properties of Detergents The concentration at which micelles formation starts is called as critical … WebThey tend to reduce surface tension of solution and thereby enhance surface active properties. Surfactants are broadly classified into four categories: anionic, cationic, …
http://labsci.stanford.edu/images/Surface-Tension-T.pdf Webreduce surface tension and increase the penetrating ability of water, thereby allowing more organic matter to be removed from surfaces. 2 Some disinfectants have detergent properties (i.e., chlorine compounds, iodophors, QACs). Detergents are classified in three categories: cationic, anionic and non-ionic. Cationic detergents
