  • Patent number: 6514923
    Abstract: Provided are aqueous hard surface cleaning and disinfecting composition which comprises the following constituents: (a) at lease one cationic surfactant having germicidal properties; and (b) a fluorosurfactant selected from the group of nonionic fluorosurfactant, cationic fluorosurfactant, and mixtures thereof, and (c) a film-forming, organosilicone quaternary ammonium compound. Optionally the compositions may further include (d) one or more detersive surfactants particularly selected from carboxylate surfactants, as well as nonionic, cationic and amphoteric surfactants, (e) one or more organic solvents, and further conventional additives.
    Type: Grant
    Filed: June 26, 2002
    Date of Patent: February 4, 2003
    Assignee: Reckitt Benckiser Inc.
    Inventors: Tak Wai Cheung, Dennis Thomas Smialowicz, Minaxi Hemansu Mehta
  • Patent number: 6440916
    Abstract: The present invention provides a process for cleaning or sanitization of hard surfaces, which process comprises the step of providing a composition containing a cationic surfactant, a fluorosurfactant, a film forming, organosilicone quaternary ammonium compound, along with optional components, and applying such a composition to a hard surface in need of cleaning.
    Type: Grant

  • Patent number: 6306810
    Abstract: Provided are aqueous hard surface cleaning and disinfecting composition which comprises the following constituents: (a) at lease one cationic surfactant having germicidal properties; and (b) a fluorosurfactant selected from the group of nonionic fluorosurfactant, cationic fluorosurfactant, and mixtures thereof, and (c) a film-forming, organosilicone quaternary ammonium compound. Optionally the compositions may further include (d) one or more detersive surfactants particularly selected from carboxylate surfactants, as well as nonionic, cationic and amphoteric surfactants, (e) one or more organic solvents, and further conventional additives. The compositions provide good sanitization of hard surfaces, and good cleaning notwithstanding the surprisingly low amount of fluorosurfactant present.

  • Patent number: 6184195
    Abstract: An aqueous concentrated liquid disinfectant composition which blooms when added to a larger volume of water which comprises the following constituents: a terpene based solvent; germicidal cationic surfactant, preferably a quaternary ammonium compound having germicidal properties; organic solvent constituent; a binary co-solvent system comprising alkyl diphenyl solvent and a co-solvent; one or more nonionic surfactants; optionally but desirably at least one optional constituent selected from: chelating agents, coloring agent, light stabilizers, fragrances, thickening agents, hydrotropes, pH adjusting agents, pH buffers one or more detersive surfactant constituents particularly non-ionic and amphoteric surfactants, as well as others known the art and useful in similar compositions; and, the balance being water. The liquid disinfectant compositions feature good blooming characteristics, particularly good long term blooming retention. Process for the use of the compositions are also disclosed.
