  • Hard surface cleaners which provide improved fragrance retention properties to hard surfaces
    Patent number: 6786223
    Abstract: Disclosed herein are hard surface cleaners which provide improved fragrance retention properties to the treated hard surface, and methods for using them. The cleaners include a fragrance, a carrier, and a surfactant selected from ethylene oxide/propylene oxide block copolymers, polyglycosides, ethoxylated alkyl alcohols, and ethylene oxide/propylene oxide copolymers functionalized with a fatty alcohol moiety. The cleaner may also contain water and a base.
    Type: Grant
    Filed: July 29, 2002
    Date of Patent: September 7, 2004
    Assignee: S. C. Johnson & Son, Inc.
    Inventors: Michael E. Klinkhammer, Richard S. Valpey, III, Brandon R. Thalmann, Mathew A. Jones, John Tsibouklis, Maureen J. Stone, Richard W. Avery
  • Hard surface cleaners containing ethylene oxide/propylene oxide block copolymer surfactants
    Patent number: 6701940
    Abstract: Disclosed herein are hard surface antimicrobial cleaners and methods for using them. The cleaners include a low concentration of high molecular weight ethylene oxide/propylene oxide block copolymer and a carrier. This provides residual benefits on the hard surface such as soil resistance and resistance to bacteria, molds, and biofilms. The cleaners contain other surfactants, and preferably also water and an organic acid.
