Definitions

  • the present invention is in the field of compact moldings which have washing and cleaning properties.
  • Such detergent tablets comprise, for example, detergent tablets for washing textiles, detergent tablets for machine dishwashing or cleaning hard surfaces, bleach tablets for use in washing machines or dishwashers, water softening tablets or stain remover tablets.
  • the invention relates to detergent tablets which are used for cleaning dishes in a domestic dishwasher and are referred to briefly as automatic dishwasher tablets.
  • Washing and cleaning tablets are widely described in the prior art and have fb as an offer form for washing and cleaning agents in addition to the usual powder 'shaped products firmly established in particular in the segment of dishwasher detergents.
  • One advantage of tablets - their ease of dosing - is perceived by some consumers as a disadvantage, since tablets with their defined amounts of ingredients take away from the consumer the right to dose.
  • the indentation of the tablets has established itself as a problem solution, so that, depending on the situation, the consumer can only use half a dosage unit by simply breaking through the tablet. This method is difficult to use with large dosing units, since too much effort is required.
  • Another disadvantage is that the amount can be determined, but all individual units have the same composition, which is why a targeted dosage of individual ingredients is impossible.
  • the agents mentioned have the disadvantage that the individual tablets either do not allow active ingredient separation or are very large and thus do not allow multiple portioning, in particular in the case of machine dishwashing agents, since the metering chambers are often very small.
  • the present invention was based on the object of providing detergent tablets and a process for their production which both allow active substance separation, if desired, and also enable space-saving multi-unit dosing in narrow dosing chambers.
  • the present invention therefore relates to a detergent tablet made of compressed, particulate detergent, containing builders and optionally further ingredients of detergents, which has one or more elevations and / or depressions on its top and on its plane-parallel to the top of the molded body Has one or more depressions and / or elevations on the underside, which can interlock positively.
  • detergent tablets is not to be understood as limiting in the context of the present invention — as already mentioned, “detergent tablets” are also understood to mean detergent tablets, detergent tablets and detergent tablets.
  • the principle described above allows it the consumer to stack several of the shaped bodies according to the invention in a space-saving manner by interlocking the elevations or depressions on the top of the first shaped body and the depressions or elevations on the underside of the second shaped body. In this way, two, three, four or even more molded articles can be stacked on top of one another and introduced into the metering chamber without space problems or the consumer having to dose the individual units several times.
  • the shaped bodies according to the invention can be equipped with a large number of elevations or depressions, so that their plane-parallel upper and lower sides also interlock positively when a shaped body is stacked laterally offset onto a second shaped body.
  • This principle would be similar to that of toy construction blocks.
  • a geometrically simpler embodiment is preferred with regard to the production of the shaped bodies, in which the detergent shaped body has an elevation and / or depression on its upper side and a depression and / or elevation on its underside which is form-fitting can interlock.

  • Preferred laundry detergent and cleaning product tablets are characterized in that the tablet base is essentially rectangular and preferably has rounded corners.
  • a detergent shaped body is preferred, which is characterized in that the shaped body base is essentially round.
  • the elevations or depressions can be realized in any size. However, for reasons of stability of the resulting shaped bodies, it has proven useful if the height of the elevations or the depth of the depressions is at most 1/50 to 1/3, preferably 1/40 to Y ⁇ , particularly preferably 1/30 to 1/5 and is in particular 1/20 to 1/6 of the distance between the mutually parallel sides of the shaped body.

  • the moldings produced according to the invention can be stacked on one another in an endless manner; however, it is also possible according to the invention to produce “end pieces” by producing a shaped body whose depression has been filled and consequently can no longer accommodate any elevation of another polymeric body.
  • Detergent tablets, in which the recess (s) on one of the molded body sides are filled with a meltable material, are therefore also the subject of the present invention.
  • Another object of the present invention is a method for producing the moldings according to the invention.

  • laundry detergent and cleaning product tablets may also contain components which have a positive influence on the oil and fat washability from textiles (so-called soil repellents). This effect becomes particularly clear if a textile is contaminated which has already been washed several times beforehand with a detergent according to the invention which contains this oil and fat-dissolving component.
  • the preferred oil and fat-dissolving components include, for example, nonionic cellulose ethers such as methyl cellulose and methyl hydroxypropyl cellulose with a proportion of methoxyl groups of 15 to 30% by weight and of hydroxypropoxyl groups of 1 to 15% by weight, based in each case the nonionic cellulose ether, and the polymers of phthalic acid and / or terephthalic acid or their derivatives known from the prior art, in particular polymers of ethylene terephthalates and / or polyethylene glycol terephthalates or anionically and / or nonionically modified derivatives thereof. Of these, the sulfonated derivatives of phthalic acid and terephthalic acid polymers are particularly preferred.

Mixtures of the aforementioned brighteners can also be used. Colorants and fragrances are added to the detergent tablets produced in accordance with the invention in order to improve the aesthetic impression of the products and to provide the consumer with a visually and sensorially "typical and unmistakable" product in addition to the softness performance.
  • fragrance compounds for example the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as perfume oils or fragrances.
  • Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutylate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethyl methylphenyl glycinate, allyl cyclohexyl benzyl propylate, propylateionate.

  • the dye content of the detergent tablets produced according to the invention is usually less than 0.01% by weight, while fragrances can make up up to 2% by weight of the entire formulation.
  • the fragrances can be incorporated directly into the agents produced according to the invention, but it can also be advantageous to apply the fragrances to carriers which increase the adhesion of the perfume to the laundry and ensure a long-lasting fragrance of the textiles due to a slower fragrance release.
  • a slower fragrance release As such have backing materials Cyclodextrins, for example, have proven themselves, the cyclodextrin-perfume complexes additionally being able to be coated with further auxiliaries.
  • the agents produced according to the invention can be colored with suitable dyes.
