Characteristic and Application of Anionic Dimeric Surfactants: A Review

Abstract Anionic dimeric surfactants have attracted much interest compared to the conventional monomeric surfactants. These surfactants have low critical micellar concentrations and an excellent ability in reducing the surface tension of water than conventional surfactants. Therewith, they also show better solubilizing and foaming properties, and a magnificent mildness to the skin. These special features may make them potentially attractive in several applications, for example, laundry detergents, cosmetics and personal care. This article describes the micellization and mixed micellization properties, performance properties, application and biodegradability of anionic dimeric surfactants.
