Definitions

  • This invention pertains to liquid detergent compositions for use in cleaning hard surfaces.
  • Such compositions typically contain detergent surfactants, solvents. builders, etc.
  • liquid detergent compositions comprise certain organic solvents, detergent surfactants, and optional builders and/or abrasives.
  • the prior art fails to teach, or recognize, the advantage of specific builders at critical levels disclosed hereinafter, in liquid hard surface cleaner formulations.
  • Liquid cleaning compositions have the great advantage that they can be applied to hard surfaces in neat or concentrated form so that a relatively high level of, e.g., surfactant material and/or organic solvent is delivered directly to the soil. Therefore, iiquid cleaning compositions have the potential to provide superior soap scum, grease, and oily soil removal over dilute wash solutions prepared from powdered cleaning compositions.
  • detergent builders in liquid hard surface cleaning compositions increases the potential to provide superior cleaning.
  • the inclusion of such detergent builders has usually produced unacceptable results for filming/streaking.
  • the inclusion of detergent builders has therefore been considered a compromise in favor of cleaning.
  • Liquid cleaning compositions and especially compositions prepared for cleaning glass, need exceptionally good filming/streaking properties. In addition, they can suffer problems of product form, in particular, inhomogeneity, lack of clarity, or excessive "solvent" odor for consumer use.
  • the present invention relates to an aqueous, liquid, hard surface detergent composition having improved cleaning and good filming/streaking characteristics comprising: (A) detergent surfactant selected from the group consisting of anionic surfactants, amphoteric detergent surfactants including zwitterionic surfactants; and mixtures thereof; (B) hydrophobic solvent; (C) alkaline material; (D) tartaric acid detergent builder; and (E) the balance being an aqueous solvent system comprising water and, optionally, non-aqueous polar solvent with only minimal cleaning action selected from the group consisting of methanol, ethanol, isopropanol, ethylene glycoi, polypropylene glycol, glycol ethers having a hydrogen bonding parameter of greater than 7.7, and mixtures thereof and any minor ingredients.
  • the compositions can be formulated at usage concentrations, or as concentrates, and can be packaged in a container having means for creating a spray to make application to hard surfaces more convenient.
  • superior aqueous liquid detergent compositions for cleaning shiny surfaces such as glass contain (A) detergent surfactant selected from the group consisting of anionic surfactants, amphoteric detergent surfactants including zwitterionic surfactants; and mixtures thereof; preferably, CO-C I Q "amphocarboxylate" detergent surfactant, zwitterionic detergent surfactant (containing both cationic and anionic groups in substantially equivalent proportions so as to be electrically neutral at the pH of use), or mixtures thereof; (B) hydrophobic, volatile, cleaning solvent; (C) alkaline buffer, preferably monoethanolamine or certain beta-amino-alkanol compounds as defined hereinafter; (D) critical level of tartaric acid detergent builder at a pH of at least about 9.5, preferably at least about 10; and (E) the balance being an a detergent surfactant selected from the group consisting of anionic surfactants, amphoteric detergent surfactants including zwitterionic surfactants; and mixtures thereof; preferably, CO-C
  • the aqueous. liquid hard surface detergent compositions herein can contain from about 0.01% to about 2.0%, more preferably from about 0.1% to about 1.0% of suitable anionic detergent surfactant of the types described hereinbefore and hereinafter.
  • the anionic surfactants are suitably water-soluble alkyl or alkylaryl compounds, the alkyl having from about 6 to about 20 carbons, including a sulfate or sulfonate substituent group.
  • the anionic detergent surfactant can be combined with a cosurfactant, preferably an amphoteric cosurfactant.
  • Nonionic surfactants e.g., ethoxylated alcohols and/or alkyl phenols, can also be used as cosurfactants.
  • the anionic detergent surfactants herein are selected from the group consisting of C 6 -C 20 alkyl sulfates, alkyl ethoxy ether sulfates, alkyl benzene sulfonates, olefin sulfonates, and mixtures thereof.
  • the anionic detergent surfactant is C 6 -C 2 o alkyl sulfate, more preferably C 8 -C
  • aqueous, liquid hard surface detergent compositions herein can contain, as the primary detergent surfactant, less preferred, or as the cosurfactant, preferably, from about 0.02% to about 15% of suitable zwitterionic detergent surfactant containing a cationic group, preferably a quaternary ammonium group, and an anionic group, preferably carboxyiate, sulfate and/or sulfonate group, more preferably sulfonate.
  • suitable zwitterionic detergent surfactant inclusion is from about 0.01% to about 1.0% of surfactant, a most preferred range is from about 0.02% to about 0.2%.
  • Zwitterionic detergent surfactants contain both a cationic group and an anionic group and are in substantial electrical neutrality where the number of anionic charges and cationic charges on the detergent surfactant molecule are substantially the same.
  • Zwitterionic detergents which typically contain both a quaternary ammonium group and an anionic group selected from sulfonate and carboxylate groups are desirable since they maintain their amphoteric character over most ofthe pH range of interest for cleaning hard surfaces.
  • the sulfonate group is the preferred anionic group.
  • Preferred zwitterionic detergent surfactants have the generic formula:
  • each Y is preferably a carboxylate (COOJ or sulfonate (SO3J group, more preferably sulfonate: wherein each Rl is a hydrocarbon, e.g.. an alkyl. or alkylene. group containing from about 8 to about 20. preferably from about 10 to about 18, more preferably from about 12 to about 16 carbon atoms; wherein each (R 2 ) is either hydrogen, or a short chain alkyl. or substituted alkyl.
  • each (R- ) is selected from the group consisting of hydrogen and hydroxy groups with no more than one hydroxy group in any (CR ⁇ pl group; wherein (R 4 ) is like R 2 except preferably not hydrogen; wherein m is 0 or 1 ; and wherein each n ⁇ or pl is an integer from 1 to about 4, preferably from 2 to about 3, more preferably about 3.
  • the R 1 groups can be branched, unsaturated.
  • R 2 groups can also be connected to form ring structures such as imidazoline, pyridine, etc.
  • hydrocarbylamidoalkylene sulfobetaines and, to a lesser extent hydrocarbylamidoalkylene betaines are excellent for use in hard surface cleaning detergent compositions, especially those formulated for use on both glass and hard-to- remove soils. They are even better when used with monoethanolamine and/or specific beta-amino alkanol as disclosed herein.
  • More preferred detergent surfactants have the generic formula:
  • each R D is an alkyl. or alkylene. group containing from about 10 to about 15 carbon atoms: each (R°) is selected from the group consisting of hydrogen, methyl, ethyl, propyl. hydroxy substituted ethyl or propyl and mixtures thereof; each (R ⁇ ) is selected from the group consisting of hydrogen and hydroxy groups wherein one of the R? groups between the (+) and the (-) charge centers is a hydroxy group and the remaining R' groups are hydrogen with no more than one hydroxy group in the (C R ⁇ : 3 moiety and n is a number from ' to about 4.
  • a more preferred specific detergent surfactant is a C j ⁇ -14 fatty acylamidopropylene(hydroxypropylene)su!fobetaine, e.g., the detergent surfactant available from the Witco Company as a 40% active product under the trade name "REWOTERIC AM CAS Sulfobetaine.”
  • the level of zwitterionic detergent surfactant, e.g., HASB. in the composition is typically from about 0.02% to about 15%, preferably from about 0.05% to about 10%.
  • the level in the composition is dependent on the eventual level of dilution to make the wash solution.
  • the composition when used full strength, or wash solution containing the composition, should contain from about 0.02% to about 1%, preferably from about 0.05% to about 0.5%, more preferably from about 0.1% to about 0.25%, of detergent surfactant.
  • the level can, and should be, higher, typically from about 0.1 % to about 10%, preferably from about 0.25% to about 2%.
  • Concentrated products will typically contain from about 0.2% to about 10%, preferably from about 0.3% to about 5%. It is an advantage of the zwitterionic detergent, e.g., HASB, that compositions containing it can be more readily diluted by consumers since it does not interact with hardness cations as readily as conventional anionic detergent surfactants. Zwitterionic detergents are also extremely effective at very low levels, e.g., below about 1%.

They also provide alkaline buffering capacity during use. However, the most unique contribution they make is to improve the filming streaking properties of hard surface cleaning compositions containing zwitterionic detergent surfactant, amphocarboxylate detergent surfactant, or mixtures thereof, whereas they do not provide any substantial improvement in filming/streaking when used with conventional anionic or ethoxylated nonionic detergent surfactants. The reason for the improvement is not known. It is not simply a pH effect, since the improvement is not seen with conventional alkalinity sources.

  • Detergent builders that are efficient for hard surface cleaners and have reduced filming/streaking characteristics at the critical levels are an essential element of the present invention. Addition of the specific detergent builder tartaric acid at critical levels to the present composition improves cleaning without the problem of filming streaking that usually occurs when detergent builders are added to hard surface cleaners. Through the present invention there is no longer the need to make a compromise between improved cleaning and acceptable filming/streaking results which is especially important for hard surface cleaners which are also directed at cleaning glass. These compositions containing the detergent builder herein at the levels herein, have exceptionally good cleaning properties.

  • Most hard surface cleaner products contain some perfume to provide an olfactory aesthetic benefit and to cover any "chemical" odor that the product may have.
  • perfume components in these perfumes are to improve the fragrance odor of the product itself, rather than impacting on the subsequent odor of the surface being cleaned.
  • some of the less volatile, high boiling perfume ingredients can provide a fresh and clean impression to the surfaces, and it is sometimes desirable that these ingredients be deposited and present on the dry surface.
  • the perfumes are preferably those that are more water-soluble and/or volatile to minimize sporting and filming.
  • the perfumes useful herein are described in more detail in U.S. Patent 5, 108,660, Michael, issued April 28, 1992, at col. 8 lines 48 to 68, and col. 9 lines 1 to 68, and col. 10 lines 1 to 24, said patent, and especially said specific portion, being inco ⁇ orated by reference.
  • Antibacterial agents can be present, but preferably only at low levels to avoid filming/streaking problems. More hydrophobic antibacterial/germicidal agents, like orthobenzyl-para-chlorophenol, are avoided. If present, such materials should be kept at levels below about 0.1 %.
  • Stabilizing ingredients can be present typically to stabilize more of the hydrophobic ingredients, e.g., perfume.
  • the stabilizing ingredients include acetic acid and propionic acids, and their salts, e.g., NH4, MEA. Na, K, etc.. preferably acetic acid and the C 2 -C( alkane diols, more preferably butane diol.
  • the stabilizing ingredients do not function in accordance with any known principle.
  • amido zwitterionic detergent surfactant with linear acyl amphocarboxylate detergent surfactant, anionic detergent surfactant, nonionic detergent surfactant, or mixtures thereof, and stabilizing ingredient can create a microemulsion
  • the amount of stabilizing ingredient is typically from about 0.01% to about 0.5%, preferably from about 0.02% to about 0.2%.
  • the ratio of hydrophobic material, e.g., perfume that can be stabilized in the product is related to the total surfactant and typically is in an amount that provides a ratio of surfactant to hydrophobic material of from about 1 :2 to about 2: 1.
  • Concentrated compositions of the present invention can also be used in order to provide a less expensive and more ecologically sound product. Concentrations of up to 10X the original concentration, preferably up to 5X, more preferably up to 2X the original concentration can be used and can be diluted using tap water, distilled water, and/or deionized water, down to a IX concentration.
