  • Aqueous cleaning and disinfecting compositions based on quaternary ammonium compounds including alkylpolyglycoside surfactants having reduced irritation characteristics
    Patent number: 6930081
    Abstract: Aqueous disinfecting and cleaning compositions and concentrates which are efficacious against gram positive and gram negative bacteria, have relatively low volatile organic content (“VOC”) and are surprisingly mild to the user of the compositions. The compositions include a quaternary ammonium compound as its primary germicidal active agent, have a low content of active constituents, and do not include organic solvents such as alcohols, glycols, or glycol ethers in significant amounts.
    Type: Grant
    Filed: March 10, 1999
    Date of Patent: August 16, 2005
    Assignee: Reckitt Benckiser Inc.
    Inventors: Robert Zhong Lu, Dennis Thomas Smialowicz, Ralph Edward Rypkema, Karen Ann McCue, Andrew Arno Kloeppel, Diane Joyce Burt, Michael David Love, Robert William Bogart, Narendra Vrajlal Nanavati, Frederic Albert Taraschi
