Abstract
A process for making substantially anhydrous structured surfactant compositions which, at room temperature, are shear thinning non-Newtonian pastes with a yield point that allows them to be easily worked in commercial apparatus. The process employs alkoxylated cationic structuring agents, anionic surfactants and organic solvents in a drying step to provide the pastes. The pastes are suitable for agglomeration with dry detergent powder to form granular detergent product and are especially suitable for incorporation into anhydrous liquid detergent products.
