Definitions

  • This invention relates to abrasive-containing hard surface scouring cleansers containing hypochlorite bleach which are thickened with a combination of a synthetic smectite clay and a polyacrylate resin. Ivlore particularly, it relates to such compositions containing particulate abrasives which maintain high active chlorine stability over a long period of time and have good rinsability.
  • Polymeric thickeners are often added to liquid products containing hypochlorite bleach in order to enhance their rheological properties so as to make them more suitable for use on non-horizontal surfaces.
  • problems encountered with such compositions is the fact that liquids containing hypochlorite bleach are destructive to most synthetic and natural thickeners.
  • thickened bleach products incorporating, as thickeners, certain polyacrylates and certain natural or synthetic clays of the smectite type which 'are somewhat less subject to degradation by the hypochlorite bleach.
  • these polymeric substances particularly the lower molecular weight polyacrylates, do not substantially increase viscosity.
  • these compositions may show initial stability, they tend to degrade, with a resultant loss of chlorine activity within a few months. Therefore, in commercial practice, unless these products are used within a relatively short period of time, they lose their effectiveness as cleaning agents.
  • the B.F. Goodrich Company produces and distributes a series of Carbopol polyacrylate resins and it is known that certain of these resins are useful in the formulation of thickened sodium hypochlorite cleaning compositions.
  • These Carbopol resins generally promote the degradation of the available chlorine in the solutions but, but certain specific Carbopol resins are relatively stable in chlorine bleach solutions in that the rate of chlorine loss is sufficiently slow for use in thickened bleach-containing cleaning compositions.
  • U.S. Patent No. 4,867,896 discloses cleaning compositions containing hypochlorite bleach thickened with cross-linked polyacrylate resins, which are said to provide improved characteristics over similar compositions thickened with certain commercially available Carbopol resins.
  • the compositions can also include smectite or attapulgite clays, and are liquid or gel type dishwashing products and do not contain abrasive particles.
  • U.S. Patent No. 4,911,857 (Machin et al.) teaches the use of polyacrylates or polymethacrylates in aqueous liquid cleaning compositions comprising suspended particulate abrasive materials.
  • the compositions can additionally contain a chlorine-releasing bleaching agent and certain Carbopol resins having molecular weights in the range of 500 to 3,000. These low molecular weight resins serve only as wetting agents. Viscosity is provided by a combination of surfactants.
  • European Patent Application No. 0606707 discloses thickened hypochlorite solutions in which the principal thickening agent is a high molecular weight cross-linked polyacrylate resin.
  • the compositions are intended for use in spray operations and do not contain abrasive particles.
  • the principal advantage to the new compositions is their reduced bleach odor.
  • PCT publication WO95/08619 discloses thickened aqueous abrasive cleansers having particulate abrasives and polyacrylate resin as a thickening agent and asserts that such cleansers have good rinsability. Nevertheless, there still remains a need for thickened abrasive bleach-containing cleansers with enhanced rinsability characteristics, particularly on horizontal surfaces, and improved stability.
  • Natural clays of the smectite or attapulgite type have been used as thickeners in cleaning compositions. See, for example, U.S. Patents Nos. 4,396,525 (Rubin), 4,877,544 (Gabriel), 4,772,414 (Marzec), 5,348,682 (Finley) and 4,235,732 (Beyer).

  • compositions have an apparent viscosity as measured on a Brookf ⁇ eld
  • RVTDV-II with a #6 spindle at 50 rpm of 2-8 Kcps and at 1 rpm of 50-200 Kcps.
  • the abrasive component of the formulation is necessary for physically scouring the stains from surfaces.
  • the abrasive agent should be present in amounts of from about 10 to about 30% by weight of the compositions; preferably, the abrasive agent is present in amounts ranging from 15 to 25%.
  • Any suitable hard inorganic particulate base-stable abrasive agent may be used.
  • Preferred abrasives include calcium carbonate and alumina trihydrate but harder abrasives such as a perlite, silica sand and various other insoluble, inorganic particulate abrasives can be used, such as quartz, pumice, feldspar, tripoli and calcium phosphate.
  • Particle size will range from average particle size of about 10 to about 500 microns, preferably from 10 to 100 microns, and more preferably from 15 to 75 microns.
  • Particle hardness of the abrasives can range from Mohs hardness of about 2-8, more preferably 3-6.
  • Especially preferred is calcium carbonate, also known as calcite. Calcite is available from numerous commercial sources such as Georgia Marble Company, and has a Mohs hardness of about 3. Typically, a size of U.S. 140 mesh is selected, although others may be appropriate.
  • the scouring composition of this invention contains a chlorine oxidizing bleach derived from a hypochlorite.
  • the hypochlorite component may be provided by a variety of sources which include sodium, potassium, lithium and calcium hypochlorites, chlorinated trisodium phosphate dodecylhydrate, potassium and sodium dichloroisocyanurate and trichlorocyanuric acid.
  • the preferred sources are sodium or potassium hypochlorite, particularly sodium hypochlorite.
  • the hypochlorite is present in the composition in an amount equal to about 0.5 to about 2.5% by weight of the composition.
  • the hypochlorite may form 0.75 to 2.0% of the composition.
  • Interaction of the cross-linked polyacrylate resin with the hypochlorite component of the composition is particularly important for maintaining the desirable characteristics of thickening and stability.
  • hypochlorite component which is preferably present in the composition contains low levels of salts such as chlorides, which would tend to interfere with the phase stability of the composition. For this reason, the present invention avoids or minimizes the use of hypochlorite bleaches formed by methods which commonly generate large amounts of salts such as sodium chloride.
  • Ordinary sodium hypochlorite bleach sold for laundry purposes can contain, for every 100 parts of NaOCl, up to 75 parts of NaCl. For purposes of this invention, it is preferred that the amount of NaCl present be not more than 20% of the amount of NaOCl.
  • the preferred hypochlorite component is preferably selected or formed in a manner avoiding or minimizing the presence of undesirable salts.
  • ordinary sodium hypochlorite bleaches are commonly formed by bubbling chlorine gas through liquid sodium hydroxide to result in formation of the corresponding hypochlorite.
  • hypochlorite bleaches produced by such reactions are undesirable for the present unless the reaction is followed by salt separation step.
  • hypochlorites formed from the reaction of chlorine with sodium hydroxide contemplates the use of hypochlorites formed in other ways, such as by reaction of hypochlorous acid with sodium hydroxide or other metal hydroxides in order to produce the corresponding hypochlorite with water as the only substantial by-product.
  • Sodium hypochlorite bleach produced in this manner is available from a number of sources, for example Olin Corporation which produces sodium hypochlorite bleach as a 36% solution in water, and sold under the trademark Hy-Pure.
  • hypochlorite component of the invention will not include chloride salt in excess of 20% of the hypochlorite.
  • the amount of chloride will be less than 5% by weight of the hypochlorite component.
  • the ionic strength of the composition has an effect on thickening. If the total ionic strength (sum of the total alkali ions plus the negative counterions) exceeds about 5 g-ions per kilogram, it becomes difficult to achieve the desired level of thickening. Moreover, ionic strength also has some effect on stability of the composition; however, the effect of ionic strength on stability is minimal relative to the effects of the cross-linked polyacrylate polymer, the synthetic clay and the polymer stabilizer. Nevertheless, the ionic strength of the compositions of the present invention should be maintained at less than about 5 g-ions/Kg, preferably less than about 3 g-ions/Kg.
  • hypochlorite component In addition to enhancing the phase stability of the composition, provided primarily by the cross-linked polyacrylate polymers, the hypochlorite component also acts as a cleaning agent.
  • the thickening system for the compositions of this invention must include a cross-linked polyacrylate polymer of the type sold by the B. F. Goodrich Company under the trademark Carbopol and by 3 V Chemical Company under the trademark Polygel.
  • These polymeric resins should have a molecular weight in the range of from about 1,000,000 to about 10,000,000, preferably from 1,500,000 to 5,000,000. (These molecular weight figures are based on data supplied in the manufacturers' product literature.)
  • a particularly suitable polymeric resin is Carbopol 695, which has a published molecular weight of about 3,000,000.
  • cross-linked polyacrylate polymers are generally characterized as acrylic acid polymers which are non-linear and water-dispersible while being cross-linked with an additional monomer or monomers in order to exhibit a molecular weight in the desired range.
  • the polymers are cross-linked with a polyalkenyl polyether, the cross-linking agents tending to interconnect linear strands of the polymer to form the cross-linked resin. It has been found that, for the purposes of achieving good long term stability, without the loss of chlorine effectiveness, the polymeric cross-linking agent must be carefully chosen within the foregoing parameters.
  • the thickening system comprises from about 0.5% to about 3% of the composition, preferably from 1% to 2.5% thereof.
  • the thickening system also comprises, in addition to the cross-linked polyacrylate polymer, from about 20% to about 80%, preferably from 50% to 80%, of its weight of a synthetic smectite-type clay similar to hectorite in structure and composition.

  • the addition of the synthetic smectite clay provides both improved rinsability, and improved stability, particularly over long time periods.
  • Surfactants are added to the composition for supplemental thickening and/or for non-thickening purposes such as cleaning, improved stability, etc. Stability in the presence of the hypochlorite component is the basic criterion for selecting the surfactants to be included in the composition.
