    Abstract: Liquid abrasive cleanser compositions sprayable through conventional manual trigger sprayers comprise a polyalkylene glycol, a nonionic surfactant, a pH adjusting agent, an abrasive, and water, wherein sprayability is made possible by the addition of the polyalkylene glycol. The compositions that are sprayable and acceptable as hard surface cleaners comprise polyethylene glycol as the polyalkylene glycol. The addition of polyethylene glycol having molecular weight of from about 4,000 to about 1,000,000 dramatically increases the sprayer output volume of liquid abrasive compositions having greater than or equal to 10 wt. % calcium carbonate. Addition of polyethylene glycol of molecular weight of from about 4,000 to about 100,000 converts otherwise non-sprayable liquid abrasive compositions into reliably sprayable compositions.

  • Patent number: 5728665
    Abstract: The present invention concerns a thickened viscoelastic cleaning formulation comprising, in aqueous solution: (a) an active cleaning compound; and (b) a viscoelastic thickening system comprising a tetradecyldialkylamine oxide and a hydrophobic organic counterion; wherein the formulation has a viscosity of at least 500 cP at 20.degree. C. The present invention is characterized as a means for reducing the characteristic "bleach odor" found in hypochlorite cleaning compositions of the prior art, particularly those which are volatilized upon dispensing. The compositions of the present invention may further be formulated to have utility as a hard surface cleaner, or as a drain opener.

  • Patent number: 5688756
    Abstract: The invention provides a gelled hypochlorite-based cleaner in which stability is achieved by reducing or minimizing the ionic strength of the cleaner, comprising:(a) a cross-linked polyacrylate polymer;(b) an amount of an bleach-stable surfactant sufficient, in combination with said polyacrylate polymer, to result in a gel;(c) an effective amount of a source of hypochlorite, which has an ionic strength below about 5M; and(d) the balance, water.
