Definitions

  • This invention relates to liquid laundry detergents and more particularly relates to such detergents containing zeolite builders.
  • surfactant structuring believed to consist of an onion-like configuration comprising concentric bilayers of surfactant molecules having water trapped therebetween — permits solid material to be stably suspended in a liquid detergent.
  • surfactant systems such as those of Corkill et al. are frequently incapable of producing a structuring phase for a liquid detergent.
  • surfactant systems suitable for this purpose can create another problem when used in an amount such as to provide a surfactant content of at least 10% by weight:
  • Liquid detergents containing such larger amounts of surfactant and suspended solids are apt to have viscosities considerably greater than 1000 mPa-s unless they also contain a viscosity-reducing polymer.
  • Corkill-like liquid detergents having the characteristics mentioned above, i.e., stable suspension of the zeolite and a maximum viscosity of 1000 mPa-s, it would be advantageous to be able to avoid having to employ a viscosity-reducing polymer in order to make the detergent pourable; and it would also be desirable for these liquid detergents to contain less auxiliary builder than the Corkill et al. powders. Having a lower auxiliary builder content would reduce the corrosivity of the detergents, lessen detriment to the environment when ecologically-undesirable auxiliary builders are employed, and provide a lower viscosity at any given zeolite level.
  • liquid detergents comprising a stable aqueous suspension of zeolite particles and having an auxiliary builder content of ⁇ 5% by weight and a viscosity of ⁇ 1000 mPa-s can be obtained without the use of a viscosity-reducing polymer when they contain certain alkylbenzene sulfonate/nonionic ethoxylate mixtures as the surfactants.
  • an aqueous surfactant-structured liquid detergent comprising:
  • the nonionic component of the admixture is an ethoxylate of an alcohol or an alkylphenol or
  • the detergent compositions of the invention are aqueous surfactant- structured liquid detergents.
  • the alkylbenzene sulfonate used as a component of the surfactant system may be any of the alkylbenzene sulfonates known to be useful as surfactants. However, it is preferably a salt, usually a sodium salt, of an alkylbenzene sulfonate in which the alkyl group contains 10-15, most preferably 11-12 carbons.
  • the ethoxylate utilized together with the alkylbenzene sulfonate to provide the surfactant mixture of the novel compositions may be an ethoxylate of an alcohol or an alkylphenol.
  • Such surfactants are well known and are compounds which usually contain alkyl groups of 8-24 carbons and 4-30 ethoxy groups.
  • the ethoxylates which have been found to be particularly useful in the practice of the invention are the C 8 -C 16 alcohol ethoxylates containing 4-12 ethoxy (EO) groups per molecule and the octylphenol and nonylphenol ethoxylates containing 6-15 EO groups per molecule.
  • the ethoxylates of alkylphenols are apt to be preferred when it is important to keep the auxiliary builder content of the compositions particularly low.
  • the optional amine oxide component of the surfactant may be any of the amine oxides conventionally employed as surfactants, typically an amine oxide corresponding to the formula RR'R"NO in which R is a primary alkyl group containing 8-24 carbons; R' is methyl, ethyl, or 2-hydroxyethyl; and R" is independently selected from methyl, ethyl, 2-hydroxyethyl, and primary alkyl groups containing 8-24 carbons.
  • Such amine oxides include, e.g., N-octyldimemylamine oxide, N,N-didecyimethyla ⁇ ine oxide, N-decyl- N-dodecylethylamine oxide, N-dodecyldimethylamine oxide, N-tetradecyldimethylamine oxide, N-tetradecyl-N-emylmemylamine oxide, N-tetradecyl-N- €myl-2-hydroxyemylamine oxide, N-hexadecyldimethylamine oxide, N-octadecyldimethylamine oxide, N,N- dieicosylethylamine oxide, N-docosyldimethylamine oxide, N-tetracosyldimethylamine oxide, and mixtures thereof — the preferred amine oxides usually being those containing one long-chain alkyl group, e.g. , N-tetradecyldimethylamine oxide.
  • the amine oxide may constitute up to 80% of the weight of the nonionic component of the surfactant as long as its concentration is not high enough to provide an amine oxide/alkylbenzene sulfonate weight ratio > 0.5/1.
  • the alkylbenzene sulfonate/nonionic surfactant proportionations required to provide surfactant structuring of the liquid detergents can vary with the particular auxiliary builder employed and with the concentrations of surfactant and auxiliary builder in the compositions — larger amounts of alkylbenzene sulfonate in the mixtures being utilizable when the compositions have the higher surfactant contents, lower alkylbenzene sulfonate/nonionic surfactant ratios being permissible when the detergents have the higher auxiliary builder contents, and the range of useful sulfonate/nonionic surfactant ratios being narrowest at the lowest levels of auxiliary builder.
  • the utilizable alkylbenzene sulfonate/nonionic surfactant weight ratios are in the range of -0.5-10/1, preferably -0.8- 5.3/1, more preferably - 1.5-4/1, and the ratios best suited for particular compositions within the scope of the invention are easily determined by routine experimentation.
  • the auxiliary builder may be any of the water-soluble inorganic and organic salts conventionally used in detergent compositions to aid the builder in sequestering "hardness" ions, such as calcium and magnesium ions.
  • exemplary of such salts are the alkali metal (e.g., sodium and potassium) carbonates, bicarbonates, silicates, chlorides, iodides, citrates, phosphates, pyrophosphates, phosphonates, nitrilotriacetates, polyacrylates, polyaspartates, polycarboxylates, and succinates.
  • auxiliary builder used in the compositions may vary from 0.5-4.5% by weight, the quantity that is preferred in any given instance depends on factors such as the particular surfactant mixture with which it is utilized, the surfactant content of the composition, and the degree to which the auxiliary builder might adversely affect the environment. Larger amounts of auxiliary builder are needed when the compositions have the lower surfactant contents, and it appears to be important to employ sufficient auxiliary builder to prevent the nonionic surfactant/ auxiliary builder weight ratio from exceeding -3.5/1. However, it is generally preferred to utilize the smaller amounts of auxiliary builder (i.e.
  • the particular zeolite employed as a builder in the novel liquid detergents is not critical as long as it is a paniculate sodium salt. Thus, although it may be a zeolite of Corkill et al., other zeolites are also utilizable. It is usually a zeolite A or X or mixture thereof, preferably zeolite A or a zeolite A/zeolite X blend.
  • liquid detergents of the invention it is not critical to combine the ingredients in any particular order. However, it is ordinarily preferred to dissolve the water-soluble surfactant mixture and auxiliary builder in water to provide the structuring phase before suspending the zeolite particles therein.
  • the invention is advantageous in its provision of all of its surfactant-structured liquid detergents, but it is particularly beneficial in its permitting the formation of the detergents having surfactant contents of 20-30% and zeolite contents of 15-45% — i.e., those having a compositional makeup which has previously necessitated the use of viscosity-reducing polymers to make them pourable.
  • the liquid detergents of the invention may include minor amounts of additives, such as the dyes, perfumes, enzymes, and preservatives frequently used in such compositions; and they could also include the viscosity-reducing polymers of known liquid detergents without losing their surfactant structuring. However, it is unlikely that it would ever be really desirable to incorporate viscosity-reducing polymers:
  • EXAMPLE 1 Prepare a series of base compositions to determine their ability to serve as the structuring phases of zeolite-containing liquid detergents. The ingredients used and the amounts employed are shown in Table I.
  • composition LAS AS AES AE NPE S-l S-2 Water
  • EXAMPLE 2 Test each of the base compositions of Example 1 for ability to serve as a structuring phase by (1) stirring zeolite particles therein to form a suspension containing 10-15% by weight of suspended zeolite, (2) storing the suspension at room temperature, and (3) examining the suspension after two months to determine its stability. The test shows that each of the suspensions made from a base composition within the scope of the invention (i.e., the compositions having an alphabetic designation with no numeric suffix) is stable, whereas there is appreciable settling of the zeolite from each of the comparative base compositions to form a second phase.
