  • Patent number: 6159916
    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.

    Abstract: A substantially homogeneous sprayable cleaning gel composition which is substantially free of suspended encapsulated particles exhibits extended dwell time when sprayed on to a surface as compared to a low viscosity spray cleaner. The extended dwell time and anti-static properties of the sprayable cleaning gel composition give rise to several benefits and advantages. The sprayable cleaning gel composition housed in a spray applicator is usable to clean surfaces at any angle. A preferred method of cleaning surfaces is also described.

  • Patent number: 5972869
    Abstract: A mildly acidic laundry detergent composition is provided for the improved protection of fine fabrics during washing and enhanced removal of generated foam during rinsing in hand wash comprising:a) at least one anionic surfactant; and/orb) at least one nonionic surfactant;c) a rinse-active, pH-sensitive foam control agent comprising a fatty acid; whereby the fatty acid foam control agent remains substantially in acid form at the mildly acidic pH of the wash water so as to be essentially inoperative to suppress foam during washing, and whereby upon rinsing of the laundry with tap water having a pH of from about 7.5 to 8.5 at least of portion of said fatty acid is converted to a soap which functions to suppress foam during rinsing.

  • Patent number: 5972817
    Abstract: A foamed glass article for preparing surfaces, the use therefor, and a method of making same are provided. The foamed glass article is in the form of a block, disk or similar product, and is used for preparing surfaces such as by sanding, rubbing and scraping the same to clean, abrade, polish, smooth, or the like such a surface. The foamed glass article is formed from a starting mixture that comprised glass, 0.10-20% by weight of at least one non-carbon/sulfate based foaming agent, and optionally an additional abrasive material. A mixture of powdered glass and non-carbon/sulfate based foaming agent can be placed in a mold and heated so that the mixture sinters and subsequently foams. Thereafter, the foamed mixture is annealed.

  • Patent number: 5962388
    Abstract: Compositions described herein are aqueous detergent compositions, preferably hard surface cleaning compositions, which contain alkyl aryl sulfonate surfactant, selected hydrophobic cleaning solvent, polycarboxylic acid, and aqueous solvent system in solution and/or a micellar phase, the pH being from about 2 to about 4. The have excellent soap scum removal and hard water deposit removal properties and are easy to rinse. Such compositions optionally contain additional anionic sulfate surfactant, cationic surfactant, peroxide and/or hydrophilic polymer for additional benefits.

  • Patent number: 5962392
    Abstract: Thickened aqueous compositions comprising soluble peracids, particularly peracetic acid are provided. The compositions are thickened by the use of one or more aliphatic alcohol ethoxylates having the general formula: R.sup.1 R.sup.2 CH--(OCH.sub.2 CH.sub.2).sub.n --OH in which R.sup.1 and R.sup.2 are each either hydrogen or linear or branched alkyl such that R.sup.1 plus R.sup.2 has a total of from 7 to 22 carbon atoms, and n is selected in the range of 1 to 15, such that the number ratio of carbon atoms in R.sup.1 plus R.sup.2 :n is greater than or equal to 3:1; and a co-surfactant selected from the group consisting of anionic surfactants, amine oxides, amphoteric surfactants and quaternary ammonium compounds.
