Definitions

  • GB-A-0 989 683 published on 22nd April 1965, discloses a process for preparing a particulate detergent from surfactants and inorganic salts; spraying on water-soluble silicate; and pressing the detergent particles into a solid form-retaining tablet.
  • a readily water-soluble organic film-forming polymer for example, polyvinyl alcohol
  • EP-A-0 002 293 published on 13th June 1979, discloses a tablet coating comprising hydrated salt such as acetate, metaborate, orthophosphate, tartrate, and sulphate.
  • the present invention provides a means by which tablets with a core which is formed by compressing a particulate material, the particulate material comprising surfactant and detergent builder, can be provided with a hard, thin, coating so that they can be stored, shipped and handled, but the coating is broken when the tablet is in the washing machine exposing the soft core which breaks up easily and rapidly, releasing the active ingredients into the wash solution.
  • the objective of the present invention is to provide a tablet which completely disintegrates and disperses in alkaline or surfactant-rich solutions such as the wash liquor.
  • Tablets to be coated in the present invention can be prepared simply by mixing the solid ingredients together and compressing the mixture in a conventional tablet press as used, for example, in the pharmaceutical industry.
  • Any liquid ingredients for example the surfactant or suds suppressor, can be incorporated in a conventional manner into the solid particulate ingredients.
  • the principal ingredients are used in particulate form.
  • the ingredients such as builder and surfactant can be spray-dried in a conventional manner and then compacted at a suitable pressure.
  • the particulate material used for making the tablet of this invention can be made by any particulation or granulation process.
  • An example of such a process is spray drying (in a co-current or counter current spray drying tower) which typically gives low bulk densities 600g/l or lower.
  • Particulate materials of higher density can be prepared by granulation and densification in a high shear batch mixer/granulator or by a continuous granulation and densification process (e.g. using Lodige ® CB and/or Lodige ® KM mixers).
  • Other suitable processes include fluid bed processes, compaction processes (e.g. roll compaction), extrusion, as well as any particulate material made by any chemical process like flocculation, crystallisation sentering, etc.
  • Individual particles can also be any other particle, granule, sphere or grain.
  • the particulate materials may be mixed together by any conventional means. Batch is suitable in, for example, a concrete mixer, Nauta mixer, ribbon mixer or any other. Alternatively the mixing process may be carried out continuously by metering each component by weight on to a moving belt, and blending them in one or more drum(s) or mixer(s). A liquid spray-on to the mix of particulate materials (e.g. non-ionic surfactants) may be carried out. Other liquid ingredients may also be sprayed on to the mix of particulate materials either separately or premixed. For example perfume and slurries of optical brighteners may be sprayed. A finely divided flow aid (dusting agent such as zeolites, carbonates, silicas) can be added to the particulate materials after spraying the non-ionic, preferably towards the end of the process, to make the mix less sticky.
  • a finely divided flow aid dusting agent such as zeolites, carbonates, silicas
  • the tablets may be manufactured by using any compacting process, such as tabletting, briquetting, or extrusion, preferably tabletting.
  • Suitable equipment includes a standard single stroke or a rotary press (such as Courtly ® , Korch ® , Manesty ® , or Bonals ® ).
  • the tablets prepared according to this invention preferably have a diameter of between 40mm and 50mm, and a weight between 25 and 60 g.
  • the compaction pressure used for preparing these tablets need not exceed 5000 kN/m 2 , preferably not exceed 3000 kN/m 2 , and most preferably not exceed 1000 kN/m 2 .
  • the tablets are then coated with a coating that is substantially insoluble so that the tablet does not absorb moisture, or absorbs moisture at only a very slow rate.
  • the coating is also strong so that moderate mechanical shocks to which the tablets are subjected during handling, packing and shipping result in no more than very low levels of breakage or attrition.
  • the coating is preferably brittle so that the tablet breaks up when subjected to stronger mechanical shock.
  • the coating material is dissolved under alkaline conditions, or is readily emulsified by surfactants. This avoids the deposition of undissolved particles or lumps of coating material on the laundry load. This may be important when the coating material is completely insoluble (for example less than 1 g/l) in water.
  • substantially insoluble means having a very low solubility in water. This should be understood to mean having a solubility in water at 25°C of less than 20 g/L, preferably less than 5 g/l, and more preferably less than 1 g/l. Water solubility is measured following the test protocol of ASTM E1148-87 entitled, "Standard Test Method for Measurements of Aqueous Solubility".
  • the used coating materials are adipic acid and C8-C13 dicarboxylic acids.
  • Preferred dicarboxylic acids are suberic acid (C8), azelaic acid (C3), sebacic acid (C10), undecanedioic acid (C11), dodecanedioic acid (C12) and tridecanedioic acid (C13).
  • substantially insoluble materials having a melting point below 40 °C are not sufficiently solid at ambient temperatures and it has been found that materials having a melting point above about 180 °C are not practicable to use.
  • the materials melt in the range from 60 °C to 160 °C, more preferably from 70 °C to 120 °C.
  • melting point is meant the temperature at which the material when heated slowly in, for example, a capillary tube becomes a clear liquid.
  • a coating of any desired thickness can be applied according to the present invention.
  • the coating forms from 1% to 10%, preferably from 1.5% to 5%, of the tablet weight.
  • the tablets further comprises an effervescent.
  • Effervescency as defined herein means the evolution of bubbles of gas from a liquid, as the result of a chemical reaction between a soluble acid source and an alkali metal carbonate, to produce carbon dioxide gas, i.e. C 6 H 8 O 7 + 3NaHCO 3 ⁇ Na 3 C 6 H 5 O 7 + 3CO 2 ⁇ + 3H 2 O
  • acid and carbonate sources and other effervescent systems may be found in : ( Pharmaceutical Dosage Forms : Tablets Volume 1 Page 287 to 291 ) An effervescent may be added to the tablet mix in addition to the detergent ingredients.
  • Nonlimiting examples of surfactants useful herein typically at levels from about 1% to about 55%, by weight include the conventional C 11- C 18 alkyl benzene sulfonates ("LAS") and primary, branched-chain and random C 10- C 20 alkyl sulfates (“AS”), the C 10- C 18 secondary (2,3) alkyl sulfates of the formula CH 3 (CH 2 ) x (CHOSO 3 -M + ) CH 3 and CH 3 (CH 2 ) y (CHOSO 3 -M + ) CH 2 CH 3 where x and (y + 1) are integers of at least about 7, preferably at least about 9, and M is a water-solubilizing cation, especially sodium, unsaturated sulfates such as oleyl sulfate, the C 10- C 18 alkyl alkoxy sulfates (“AE x S”; especially EO 1-7 ethoxy sulfates), C 10- C 18 alkyl alkoxy carboxylates (especially the
  • the conventional nonionic and amphoteric surfactants such as the C 12- C 18 alkyl ethoxylates ("AE") including the so-called narrow peaked alkyl ethoxylates and C 6 -C 12 alkyl phenol alkoxylates (especially ethoxylates and mixed ethoxy/propoxy), C 12- C 18 betaines and sulfobetaines ("sultaines"), C 10- C 18 amine oxides, and the like, can also be included in the overall compositions.
  • the C 10 -C 18 N-alkyl polyhydroxy fatty acid amides can also be used. Typical examples include the C 12 -C 18 N-methylglucamides. See WO 9,206,154 .
  • non-phosphate builders are required in some locales.
  • the compositions herein function surprisingly well even in the presence of the so-called "weak” builders (as compared with phosphates) such as citrate, or in the so-called "underbuilt” situation that may occur with zeolite or layered silicate builders.
  • silicate builders are the alkali metal silicates, particularly those having a SiO 2 :Na 2 O ratio in the range 1.6:1 to 3.2:1 and layered silicates, such as the layered sodium silicates described in U.S. Patent 4,664,839, issued May 12, 1987 to H. P. Rieck .
  • silicates may also be useful such as for example magnesium silicate, which can serve as a crispening agent in granular formulations, as a stabilizing agent for oxygen bleaches, and as a component of suds control systems.
  • carbonate builders are the alkaline earth and alkali metal carbonates as disclosed in German Patent Application No. 2,321,001 published on November 15, 1973 .
  • Aluminosilicate builders are useful in the present invention. Aluminosilicate builders are of great importance in most currently marketed heavy duty granular detergent compositions, and can also be a significant builder ingredient in liquid detergent formulations.
  • polycarboxylate builders encompasses the ether polycarboxylates, including oxydisuccinate, as disclosed in Berg, U.S. Patent 3,128,287, issued April 7, 1964 , and Lamberti et al, U.S. Patent 3,635,830, issued January 18, 1972 . See also "TMS/TDS" builders of U.S. Patent 4,663,071, issued to Bush et al, on May 5, 1987 .
  • Suitable ether polycarboxylates also include cyclic compounds, particularly alicyclic compounds, such as those described in U.S. Patents 3,923,679 ; 3,835,163 ; 4,158,635 ; 4,120,874 and 4,102,903 .

  • a particularly preferred compound of this type is dodecenylsuccinic acid.
  • succinate builders include: laurylsuccinate, myristylsuccinate, palmitylsuccinate, 2-dodecenylsuccinate (preferred), 2-pentadecenylsuccinate, and the like. Laurylsuccinates are the preferred builders of this group, and are described in European Patent Application 86200690.5/0,200,263, published November 5, 1986 . Other suitable polycarboxylates are disclosed in U.S.
  • Suitable lipase enzymes for detergent usage include those produced by microorganisms of the Pseudomonas group, such as Pseudomonas stutzeri ATCC 19.154, as disclosed in British Patent 1,372,034 .
