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.

Abstract: A detergent composition having a plasma-induced, water-soluble coating for controlling solubility, chemical stability and physical properties is disclosed. A process for making such a detergent composition is also disclosed which involves subjecting a detergent material to a plasma glow zone in which an organic hydrophilic monomer is introduced such that it ultimately deposits on the detergent material to form a water-soluble coating. The detergent compositions are particulate or non-particulate and can be used for laundry, dishwashing or other similar application.
