  • Patent number: 6462012
    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 applications.
