Detergents are classified in three categories: cationic, anionic and non-ionic. Cationic detergents WebThey tend to reduce surface tension of solution and thereby enhance surface active properties. Surfactants are broadly classified into four categories: anionic, cationic, zwitter-ionic and non-ionic. Anionic and cationic have permanent negative and positive charges, respectively. Non-ionic detergents do not have any phone housing authority taos
