  • Patent number: 6268324
    Abstract: A low viscosity aqueous cleaning composition provides increasing viscosity upon dilution which provides a high viscosity diluted cleaning composition having solvents compatible with the rod micelle thickener and the cleaning system that clings for an extended period of time in a thickened form containing cleaning system ingredients that can penetrate and remove hard baked-on soils on vertical surfaces in cleaning units. The composition contains active cleaning ingredients (acid, alkaline and enzyme) that, in combination with thickening systems, provide the useful properties. The thickened materials can be applied on cold or hot surfaces and can successfully penetrate, soften and remove baked-on food soil on a variety of surfaces including oven walls, doors and grills, baking dishes, utensils, etc.

  • Patent number: 6247478
    Abstract: A method for cleaning polyethylene terephthalate containers including contacting the PET container with an alkaline wash solution having a temperature ranging of less than about 60° C. is disclosed. The alkaline wash solution is formulated from a first concentrate, a second concentrate, an alkalinity source, and a balance of water. The first concentrate preferably has a first nonionic surfactant, a first builder, and acid in an amount effect to provide a phase stable solution. The second concentrate preferably has a second nonionic surfactant and a second builder. The first and second concentrate are present in the wash solution in a concentration ranging from about 0.3 wt. % to 2.0 wt. %. Preferably, the first nonionic surfactant has a cloud point ranging from about 5° C. to 60° C.

  • Patent number: 6248178
    Abstract: A method is disclosed for removing pad nodules. The method provides a wafer comprising pads and pad nodules which are formed on said pads, wherein said pads are made from a metal selected from the group consisting of aluminum and an aluminum-copper alloy. Then, the method dips the wafer into deionized water for removing the pad nodules. Thereafter, the method spin-dries the wafer and coats an alkaloid developer on the wafer for further removing the pad nodules. Finally, the method removes the alkaloid developer from the wafer and bakes the wafer.

  • Patent number: 6242402
    Abstract: An improved cleaning composition is provided for shower and tub surfaces which is of the “shower rinsing” type, requiring no scrubbing, wiping, or immediate rinsing. The composition comprises: (a) a glycoside surfactant, the total amount of said surfactant being present in a cleaning effective amount; (b) a chelating agent, said chelating agent present in an amount effective to enhance bathroom soil removal in said composition; and (c) the remainder, water. A solvent such as isopropyl alcohol may also be added. The employment of a glycoside surfactant, especially one having an HLB value of greater than 13, remarkably improves the performance of such a shower rinsing composition both with respect to surface appearance streaking and filming and also bathroom soil and soap scum removing ability.

  • Patent number: 6232280
    Abstract: A cleaning composition includes a detectable substance which is relatively stable in the cleaning composition, for indicating whether the cleaning composition has been thoroughly removed from a vessel following a cleaning process. For pharmaceutical applications, the detectable substance is preferably a low-foaming surfactant that is detectable by high performance liquid chromatography at concentrations of around 10 ppm, or less. The surfactant is thus detectable in the same analytical procedure as are traces of pharmaceutical residues which have not been removed from the vessel. The analytical procedure is used to develop a cleaning protocol for future cleaning processes by determining the number of rinses needed for reducing the surfactant, and hence the cleaning product, and also the pharmaceutical residues, in the rinse water to predetermined acceptable levels.

  • Patent number: 6191094
    Abstract: An alkaline aqueous cleaning composition for cleaning a substrate contaminated with industrial-type soil contaminants contains (i) an aqueous portion and (ii) an active-ingredient portion composed of (A) an alkalinity-providing agent and (B) a surfactant mixture containing (a) an active concentration of an ethoxylated C12-14 alkanol surfactant having an HLB value at 25° C. of from 8 to 12 and (b) an active concentration of at least one aminocarboxylic acid surfactant of the general formula R—N(H)—R′, wherein R is a straight or branched chain aliphatic organic group having from 10 to 20 carbon atoms, and R′ is a straight or branched chain carboxylic acid having from 1 to 7 carbon atoms. At an active-concentration ratio of surfactant (a) to surfactant (b) of about 2.5:1, the surfactants have a synergistic effect on the cleaning composition's ability to remove certain types of industrial-soil contaminants.
