  • Patent number: 7879787
    Abstract: An oxidizing cleaning composition comprises a low concentration of aqueous hydrogen peroxide that is environmentally friendly and has good stability in strong alkaline solutions. The aqueous hydrogen peroxide composition contains a synergistic combination of one or more hydrophilic surfactants having an HLB of 10 or greater, one or more hydrotropes, one or more UV-analyzable surfactants having an aromatic detectable functional group, and optionally a surfactant having an HLB of less than 10. The cleaning composition when mixed with an alkaline compound is very effective in removing dried or baked residues of polymers, modified or natural celluloses starches, natural gels, and the like at low concentrations and temperatures.
    Type: Grant

    Date of Patent: February 1, 2011
    Assignee: American Sterilizer Company
    Inventors: Stavroula Maria Heintz, Shannon K. Campbell, Gurusamy Manivannan
  • Patent number: 7854349
    Abstract: Self-heating, post-foaming shave gels and shave gel products are provided. In some implementations, the shave gels include a non-ionic emulsifier system, e.g., including one or more fatty alcohol ethoxylates.

  • Patent number: 7838485
    Abstract: An aqueous, alkaline cleaning composition for use on hard-to-clean soils, encountered in pharmaceutical, personal care, food and cosmetic manufacturing, comprising a source of alkalinity, a biodegradable surfactant system further comprising one or more surfactants, one or more hydrotropes, and a UV-analyzable surfactant, and a biodegradable chelating agent. The composition offers unique advantages of stability over the expected shelf life, low-foaming property, phosphate-free and biodegradable components, and unexpectedly enhanced antimicrobial, including virucidal, activity in one cleaning composition. The UV-analyzable surfactant allows for validation of cleaning processes using known techniques for manufacturers who are required or desire to do so.

  • Publication number: 20050175575
    Abstract: The present invention is directed to shaving compositions that include water insoluble lubricating polymer particles and/or one or more water soluble polymers. Some preferred compositions include a lubricating agent that contains water insoluble lubricating polymer particles and a blend of two or more water soluble polymers having different molecular weights. The invention is also directed to methods of shaving in which a shaving composition of the present invention is applied to an area of skin, then said area is shaved, preferably with a wet razor.

  • Publication number: 20030147925
    Abstract: The present invention relates to a topical antimicrobial composition containing an antimicrobial complex that provides sustained antimicrobial disinfecting action upon contact with microorganisms for prolonged periods, without the necessity for reapplication. The topical antimicrobial composition provides both initial and residual contact-killing disinfecting activity, and does not release its antimicrobial components into contacting liquids at levels that result in solution disinfection.
