Definitions

  • the invention relates to aqueous high sudsing liquid detergent compositions containing specified amounts and types of surfactants especially useful in the washing of tableware, kitchenware and other hard surfaces.
  • compositions of this invention provide more complete drainage of rinse water from surfaces such as glass, ceramics and metal, thereby reducing spotting and filming, particularly in a dishwashing procedure that involves drain drying without towel drying and polishing.
  • the performance of a detergent composition for cleaning glasses, dishes, and other articles with a normally shiny surface is evaluated by the consumer in terms of shine and the absence of filming, streaking, and spotting.
  • the liquid dishwashing detergent compositions presently on the market are designed to remove the soils from glasses, dishes, and other tableware and kitchen utensils.
  • the detergent solution and redeposited soil residues are normally removed from the washed articles by rinsing and optionally by towel drying the articles when they are still wet. If not rinsed and towel dried, these residues can dry upon the surfaces of the washed articles, leaving films, streaks, or spots.
  • U.S. Patent 3,963,649, Spadini et al discloses liquid detergent compositions containing a nonionic surfactant and a water-soluble gel-forming gelatin. These compositions are said to minimize filming, streaking and spotting of tableware and kitchen utensils.
  • the essential nonionic surfactant may be a tertiary amine or phosphine oxide, an amide or a condensation product of ethylene oxide and an organic hydrophobic compound.
  • U.S. Patent 3,983,079, Spadini et al discloses dishwashing detergent compositions said to have good rinse water draining characteristics.

  • the ethoxylated nonionic surfactants of the present invention are the condensation product of alcohols, alkyl phenols and other specified hydrophobic molecules with ethylene oxide.
  • the materials hereinafter disclosed have not been used in aqueous liquid detergent compositions having the required formulation characteristics of the present invention. Their ability to improve rinse water drainage characteristics had not been recognized.

  • ethoxylated nonionic surfactants at a level of from 2% to 20% can provide the drainage promoting characteristics of ethoxylated alcohols, but are less desirable for reasons of biodegradability and effect on sudsing or cleaning performance.
  • ethoxylated nonionic surfactants are:
  • an aliphatic alcohol contains from 16 to 22 carbon atoms and is ethoxylated to an average degree of from 18 to 50 moles of ethylene oxide per mole of alcohol.
  • compositions of this invention contain from 1.5% to 10%, preferably from 2% to 8%, of suds stabilizing nonionic surfactant or mixture thereof having a different chemical structure and function than the essential drainage promoting nonionic surfactant.
  • Suds stabilizing nonionic surfactants operable in the instant compositions are two basic types- amides and the amine oxide semi-polar nonionics.
  • the amide type of nonionic surface active agent include the ammonia, monoethanol and diethanol amides of fatty acids having an acyl moiety of from 8 to 18 carbon atoms and represented by the general formula wherein R 1 is a saturated or unsaturated, aliphatic hydrocarbon radical having from 7 to 21, preferably from 11 to 17 carbon atoms; R 2 represents a methylene or ethylene group; and m is 1, 2, or 3, preferably 1 or 2.
  • Specific examples of said amides are mono-ethanol coconut fatty acid amide and diethanol dodecyl fatty acid amide.
  • acyl moieties may be derived from naturally occurring glycerides, e.g., coconut oil, palm oil, soybean oil and tallow, but can be derived synthetically, e.g., by the oxidation of petroleum, or hydrogenation of carbon monoxide by the Fischer-Tropsch process.
  • the monoethanol amides and diethanolamides of C 12-14 fatty acids are preferred.
  • Amine oxide semi-polar nonionic surface active agents comprise compounds and mixtures of compounds having the formula: wherein R 3 is an alkyl, 2-hydroxyalkyl, 3-hydroxyalkyl, or 3-alkoxy-2-hydroxypropyl radical in which the alkyl and alkoxy, respectively, contain from 8 to 18 carbon atoms, R 4 and R 5 are methyl, ethyl, propyl, isopropyl, 2-hydroxyethyl, 2-hydroxypropyl, or 3-hydroxypropyl and n is from 0 to 10.

  • compositions of the invention are those which will provide the user of the product with an indication of cleaning potential in a dishwashing solution. Soils encountered in dishwashing act as suds depressants and the presence or absence of suds from the surface of a dishwashing solution is a convenient guide to product usage.
  • Mixtures of anionic surfactants and suds stabilizing nonionic surfactants are utilized in the compositions of the invention because of their high sudsing characteristics, their suds stability in the presence of food soils and their ability to indicate accurately an adequate level of product usage in the presence of soil. Additionally, and most importantly, compositions containing the other two essential surfactants of the invention but not the suds stabilizing nonionic surfactants as defined herein, do not provide an optimum draining promoting effect.
  • the ratio of anionic surfactants to total nonionic surfactants in the composition will be in a molar ratio of from 11:1 to 1:1, and more preferably from 8:1 to 3:1.
  • the suds stabilizing nonionic surfactants are generally preferred, but the essential relatively highly ethoxylated drainage promoting nonionic surfactants of the invention can contribute to sudsing performance and are included in the calculation of ratios of anionic to nonionic surfactant.

  • Ampholytic surfactants can be broadly described as derivatives of aliphatic amines which contain a long chain of 8 to 18 carbon atoms and an anionic water-solubilizing group, e.g. carboxy, sulfo or sulfate. Examples of compounds falling within this definition are sodium-3-dodecylamino propane sulfonate, and dodecyl dimethylammonium hexanoate.
  • Zwitterionic surface active agents operable in the instant composition are broadly described as internally-neutralized derivatives of aliphatic quaternary ammonium and phosphonium and tertiary sulfonium compounds in which the aliphatic radical can be straight chain or branched, and wherein one of the aliphatic substituents contains from 8 to 18 carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfo, sulfato, phosphato, or phosphono.
  • Cationic surfactants such as quaternary ammonium compounds can find optional use in the practice of the invention to the extent they are compatible with the other surfactants in the particular composition.
  • compositions of this invention contain at least 20%, preferably from 40% to 70%, water.
  • compositions of this invention can contain up to 10%, by weight of detergency builders either of the organic or inorganic type.

  • specific examples of such salts are sodium tripolyphosphate, sodium carbonate, potassium carbonate, sodium pyrophosphate, potassium pyrophosphate, potassium tripolyphosphate, and sodium hexametaphosphate.
  • organic builder salts which can be used alone, or in admixture with each other or with the preceding inorganic alkaline builder salts, are alkali metal polycarboxylates, e.g., water-soluble citrates such as sodium and potassium citrate, sodium and potassium tartrate, sodium and potassium ethylenediaminetetraacetate, sodium and potassium N-(2-hydroxyethyl)-ethylene diamine triacetates, sodium and potassium nitrilo triacetates (NTA) and sodium and potassium N-(2-hydroxyethyl)-nitrilo diacetates.
  • Other organic detergency builders such as water-soluble phosphonates can find use in the compositions of the invention. In general, however, detergency builders have limited value in dishwashing detergent compositions and use at levels above 10% can restrict formulation flexibility in liquid compositions because of solubility and phase stability considerations.
  • Alcohols such as ethyl alcohol, and hydrotropes, such as sodium and potassium toluene sulfonate, sodium and potassium xylene sulfonate, trisodium sulfosuccinate and related compounds (as disclosed in U.S. Patent 3,915,903), and urea, can be utilized in the interest of achieving a desired product phase stability and viscosity.
  • Ethyl alcohol at a level of from 3% to 15% and potassium or sodium toluene, xylene or cumene sulfonate at a level of from 1% to 6% are particularly useful in the compositions of the invention.
  • the detergent compositions of this invention can contain, if desired, any of the usual adjuvants, diluents and additives, for example, perfumes, enzymes, dyes, anti-tarnishing agents, antimicrobial agents, and the like, without detracting from the advantageous properties of the compositions.
  • adjuvants for example, perfumes, enzymes, dyes, anti-tarnishing agents, antimicrobial agents, and the like.

  • Dinner plates were washed with the introducing of 4.0 ml of a triglyceride-containing soil on each plate. Suds height is measured after washing sets of five plates. This procedure is repeated five times for a total of 25 plates. The suds height after washing each set is expressed in terms of percent of original suds height and an average of the five values is reported as suds during washing (SDW). The number of plates washed when suds disappear from the surface of the dishwashing solution is recorded as "mileage".
  • Compositions A and B had sudsing characteristics equivalent to C and provided a superior appearance and freedom from spotting and filming after washing and rinsing.
  • compositions A and B are substituted for the tallow alcohol-ethoxy (22) in Compositions A and B:
  • liquid dishwashing detergent compositions were prepared:
  • composition D For purposes of evaluating spotting and filming performance a variation of Composition D was prepared in which 5% tallow alcohol-ethoxy (22) replaced 5% water. Similarly variations of Composition E were prepared in which 1 %, 5% and 20% tallow alcohol-ethoxy (22) replaced water.

Graders assigned values of +4 to -4 to indicate their satisfaction or dissatisfaction with the end result apperance of the glasses.
  • Composition G provided a significant appearance advantage relative to the other three compositions.
  • Compositions H and I provided a numerical advantage over Composition J not statistically significant at a 95% confidence level. Only Composition G provided results on the positive side of the satisfaction scale.
