Definitions

  • a phosphate-free detergent composition is described.
  • the present invention relates to a novel built detergent composition having general utility as a laundering agent and which is phosphate-free.
  • Detergent actives such as polypropylene benzene sulfonates, however, are not the only materials present in detergent formulations.
  • an effective detergent composition can be formulated consisting essentially of (a) from about 4% to about 85% by weight of a water-soluble salt of a dianionic detergent compound of the general formula Y X A (r%) (t.
  • Y is selected from the class consisting of unsubstituted, mono-methyl substituted and mono-hydroxy substituted straight-chain hydrocarbon groups containing from 15 to 20 carbon atoms
  • a detergent formulation which is as effective as a formulation based on the heretofore generally accepted alkylbenzene sulfonate detergents and built with phosphates.
  • the dianionic detergent may be selected from biodegradable actives and the like, and since the amount of heavy-metal salt needed is relatively slight, no significant contamination of surface and ground waters results from detergents of the present formulation.
  • a composition according to the invention also has an advantage over a phosphate-built composition in that there is a much reduced tendency for separation of particulate matter to occur if the composition is formulated as a liquid.
  • a detergent formulation employing the present invention consists essentially of from about 4% to about 85% of said dianionic detergent and from about 1%. to about 80% of said heavy-metal salt, the balance being water or any of the other usual detergent adjuvants. It Will be understood that for the primary advantage of the present invention to be obtained, the composition must be phosphate-free. In particular, the composition must not contain any phosphate builder.
  • the compounds of the above general formula can be described as dianionic detergents because they contain two anionic functional groups, i.e., sulfate, sulfonate or phosphonate groups. This is not to be confused with the valency of the anionic functional groups.
  • Typical detergents which may be used in accordance with the present invention are the salts with water-solubilizing cations of dianionic sulfates, sulfonates and phosphonates.
  • the water-solubilizing cations include the customary cations known in the detergent art, i.e., the alkali metals, (i.e., Li, Na, K, Rb and Cs), ammonium and substituted ammonium, and the alkaline earth metals, as well as other metals in Groups II-A, II-B, III-A, IV-A, and IV-B of the Periodic Table except for boron.

  • M of the above formulas
  • the cations most widely used commercially are sodium, potassium and ammonium.
  • M may be any of the alkali metals, ammonium or a substituted ammonium compound.
  • substituted ammonium compounds triethanol ammonium and morpholinium salts are particularly common.
  • the cation M may also be selected from the water-soluble alkaline earth salts, i.e., the calcium, magnesium, strontium or barium salts of the disulfates and disulfonates.
  • the disulfates and disulfonates typically being prepared by adding a sulfate or sulfonate group to an unsaturated linkage, the disulfate and disulfonate detergents are typically substantially saturated. It should be understood, however, that substantial saturation is not an essential element of the present invention.
  • Significant saturation is not an essential element of the present invention.
  • Favorable response to the presence of said heavy-metal ions occurs when using unsaturated disulfates or disulfonates as well as when using saturated compounds.
  • a still further modification which should be mentioned, is the possibility of using mixed anionic detergents, e.g., compounds of the Formulas Y(SO (SO )M and Y(SO M)(PO M which also behave similarly to the compounds mentioned above.
  • dianionic detergents are compounds in which one of the anionic groups is attached to the hydrocarbon group by a low molecular weight linking group.
  • X is the linking group.
  • One of the sulfonate, sulfate or phosphonate groups is attached to the linking group.

  • linking groups have been Widely used in the detergent art. Typical such groups which can be used in the present invention include the oxyalkylene, amidoalkylene, aminoalkylene, carboxylic ester, phenylene, phenylenealkylene, phenyleneoxy and phenyleneoxyalkylene.
  • Oxyalkylene linkages can be prepared by reacting an unsubstituted or mono-methyl substituted alcohol containing from 15 to 20 carbon atoms with a C C alkylene oxide.
  • the commercially most significant alkylene oxide is ethylene oxide. Reaction of ethylene oxide with an alcohol increases the hydrophilic character of the alcohol. This is in contrast to reaction of other alkylene oxides, such as propylene oxide, with an alcohol when hydrophilic character is increased.
  • X can be Compounds containing an ether linkage, i.e., oxyalkylene link, can also be derived from glycerol ethers. In such compounds the two free hydroxy groups of glyceryl moiety can be converted to sulfate, sulfonate or phosphonate.
  • Compounds containing an ether linkage can also be prepared by reacting a suitable alcohol with chlorhydrin.
  • the product can be converted to a sulfate, sulfonate or phosphonate or can be reacted with ethylene oxide, as above this can involve reaction with up to 5 moles of ethylene oxide, and then converted to a sulfate, sulfonate or phosphonate.
  • the amido linkage (i.e., CONH) which can be used in combination with a C -C alkylene group can be prepared by sulfating a monoethanol amide.
  • the second nitrogen-attached hydrogen can also be substituted (i.e., -CO-NR where R is an alkyl group) but the total number of carbon atoms in the linking group should not be more than 6.
  • Compounds of the general class can be prepared by reacting a B-amino-sulfate or a taurine (i.e., a fi-aminosulfonate) with C -C fatty acids containing a sulfatable, sulfonatable or phosphonatable group.
  • compounds of the same general type may be prepared by reacting higher molecular weight fatty amines with lower molecular weight carboxylic acids.
  • appropriate compounds may be prepared by reacting a hydroxy fatty amine with a hydroxy carboxylic acid (for example, lactic acid).
  • the resulting lactyl amide can then be converted to a disulfate by reaction with a sulfating agent.
  • the amino linkage which should contain from 1 to 6 carbon atoms, can be prepared similarly, for example, by reaction of a B-amino-sulfate with C -C fatt halide containing a sulfatable, sulfonatable or phosphontable group.

  • the heavy metal ions employed as builders in the present invention are derived from the water-soluble, innocuous salts of calcium, barium, strontium, magnesium or aluminum, i.e., their salts with innocuous acids.
  • innocuous acid it will be understood that the acid portion of the salt is so selected that it is free of objectionable color or toxicity which would interfere with the intended use of the detergent composition and is free of groups which would adversely react with the other components of the detergent formulation.
  • At least about 1.2 mols of the heavy metal ion should be provided for each mole of dianionic detergent.
  • a portion of the heavy metal ion can, if desired, be supplied by employing the dianionic detergent in the form of its appropriate salt. This, however, will supply only approximately 1 mole of heavy metal ion for each mole of dianionic detergent. Thus, to obtain the most satisfactory results, provision must be made for supplemental water-soluble salts of suitable heavy metals.
  • Detergent formulations within the present invention preferably contain up to about 16 moles of heavy metal ion per mole of dianionic detergent. Preferred compositions have from 2 to 8 moles of heavy metal ion per mole of detergent.

This series of mixtures, together with a detergent composition containing only the pure disulfate were tested for detergency on Foster D. Snell soil cloth in a Terg-O-Tometer. No other builders were employed. For comparison, alkyl benzene sulfonate was tested in the same series. Distilled water was used in all cases with the following results:
