In general, the viscosity of aqueous surfactant solutions is low and does not meet the elevated viscosity operating requirements of some practical applications. Inorganic salts are the most widely used thickeners, but they are not suitable for all application systems, such as the Linear Alkylbenzene Sulfonate (LAS) system. Polymer thickeners are comb-like compounds with many hydrophobic groups. These groups in solution through intermolecular forces form a network, increasing the viscosity of the system. In addition, non-ionic surfactant fatty alcohol polyoxyethylene ether has an excellent surface activity. If the product is combined with surfactants and polymers, it is possible to increase the viscosity of the system without degrading the application performance.
