Abstract
A process for making substantially anhydrous 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 hydrotropes, anionic surfactants and nonionic surfactants in a drying step to provide the pastes. The pastes are especially suitable for incorporation into anhydrous liquid detergent products.
