  • Patent number: 7828908
    Abstract: A biodegradable acid cleaning composition for cleaning stainless steel, and other surfaces is disclosed. The composition comprises urea sulfate in combination with gluconic acid which serves as a corrosion inhibitor. The composition retains the cleaning and corrosion prevention properties of similar phosphoric acid solutions but is safe for the environment and is less expensive to produce. Applicants have surprisingly found that the traditionally alkaline corrosion inhibitor, gluconic acid, can work effectively in an acidic cleaning composition.

  • Patent number: 7781388
    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.
