  • Patent number: 10683472
    Abstract: Disclosed herein are methods for improving safety and delivery of commercial application of cleaning compositions that include enzymes and other protein irritants. The methods reduce the mist and aerosolization of proteins so that inhalation and exposure to the same are reduced. According to the invention, when commercial pressurized sprayers are used to apply protein containing use cleaning compositions of up to 5 ppm protein, aerosolization is decreased to below 60 ng active protein per meter cubed. Applicants have also identified a specific metering tip/nozzle, dispense rate, and low pressure application of not more than 100 psi are critical to achieving the benefits of the invention.
    Type: Grant

  • Publication number: 20110197465
    Abstract: A water removal composition and methods for using the same to remove excess water from a surface. The composition comprises a silicone polymer, quaternary ammonium emulsifier, co-emulsifier and an HLB stabilizing agent that modifies a treated surface to form a continuous hydrophobic layer enhancing water removal from the surface. The novel water removal compositions and methods for using the same result in a significant reduction of energy expenditure to remove excess water through air blowers and/or mechanical removal.
