    Assignee: Procter & Gamble Company
    Inventors: AndréCesar Baeck, Johan Smets, Stanton Lane Boyer
  • Patent number: 6833347
    Abstract: Disclosed are detergent compositions and methods which utilize certain modified cellulose ethers as fabric treatment agents that can impart fabric appearance and integrity benefits to fabrics and textiles laundered in washing solutions which contain such agents. Such modified cellulose ether fabric treatment agents are those having selected types and amounts of anhydroglucose ring substituents in order to render them nonionic, cationic or anionic in nature.
    Type: Grant

  • Patent number: 6541438
    Abstract: The present invention relates to a modified enzyme which comprises a catalytically active amino acid sequence of a cellulolytic enzyme linked to an amino acid sequence comprising a Cellulose Binding Domain (CBD) having a relative binding constant (Kr-a) for binding to amorphous cellulose higher than 2.4 l/gcellulose, preferably higher than 3.5 l/gcellulose, more preferably higher than 4 l/gcellulose, for selective binding and hydrolysis of amorphous cellulose of cotton containing fabrics in a laundry and/or fabric care application. The present invention further relates to laundry detergent and/or fabric care compositions comprising this modified enzyme.
    Type: Grant
    Filed: January 30, 2001
    Date of Patent: April 1, 2003
    Assignee: The Procter & Gamble Company
    Inventors: Johan Smets, Alfred Busch, André Cesar Baeck, Jean-Luc Philippe Bettiol, Stanton Lane Boyer
  • Patent number: 6468955
    Abstract: Modified enzymes which comprise a catalytically active amino acid sequence of an enzyme, linked via a non-mino acid linking region to an amino acid sequence comprising a Cellulose Binding Domain. The present invention further relates to laundry detergent and/or fabric care compositions comprising such modified enzymes. These compositions provide a higher effective concentration of the enzyme at its substrate location and therefore, improved enzymatic benefits.
    Type: Grant
    Filed: November 1, 2000
    Date of Patent: October 22, 2002
    Assignee: The Proctor & Gamble Company
    Inventors: Johan Smets, Jean-Luc Philippe Bettiol, Stanton Lane Boyer, Alfred Busch
  • Patent number: 6465410
    Abstract: A modified protein which comprises a catalytically active amino acid sequence of an antimicrobial enzyme and/or an amino acid sequence of an antimicrobial peptide linked to an amino acid sequence comprising a cellulose binding domain (CBD), and laundry detergents and/or fabric care compositions comprising such modified protein for improved sanitization benefits, are provided by the present invention.
    Type: Grant

    Assignee: The Procter & Gamble
    Inventors: Jean-Luc Philippe Bettiol, Johan Smets, Stanton Lane Boyer
  • Patent number: 6410498
    Abstract: The present invention relates to a modified enzyme which comprises a catalytically active amino acid sequence of a transferase linked to an amino acid sequence comprising a Cellulose Binding Domain (CBD). The present invention further relates to laundry detergent and/or fabric care compositions comprising such modified enzyme, for improved fabric care and cleaning benefits.
    Type: Grant

  • Patent number: 6322595
    Abstract: A detergent composition comprising a combination of cellulase enzymes is provided. The detergent composition comprises at least 1% by weight of a surfactant, at least 1% by weight of a builder and an effective amount of an enzymatic mixture capable of degrading cellulose. The enzymatic mixture comprises a combination of at least two cellulases, of which one is a surface-active cellulase having a cellulose-binding domain, and one is a nonsurface-active cellulase which does not possess a cellulose-binding domain. The nonsurface-active cellulase and the surface-active cellulase are in a weight ratio of from 1:2 to 20:1 in the detergent composition.
