Definitions

  • the present invention relates to a product for a washing appliance and to uses of said product.
  • the method of use of this type of product envisages running a complete empty cycle by setting a high temperature programme.
  • the empty cycle needs to be run because, given the highly acid pH of the product, the concomitant use with the classic detergents for dishwashers would cause the inactivation of the enzymes contained in the detergents, significantly worsening the performance of washing the crockery.
  • the need to opt for an intensive programme is determined by the fact that the dishwasher care products are generally packaged in bottles (typically 250ml) of water-resistant (non-biodegradable) plastic provided with a special cap consisting of a septum of meltable wax at temperatures above 45-50°C. The product therefore starts its action in the central washing step when the temperature of the dishwasher is sufficient to melt the wax.
  • the dishwasher cares currently on the market come in a monophasic or biphasic version.
  • the anti-scale products for washing machines are liquid products with high dilution (H 2 O>80%) preferably with variable pH 4 to 7 which are added directly into the compartment of the washing machine together with the detergent at each wash.
  • the anti-scale products therefore cooperate with the detergent by sequestering the limescale present, thus improving the cleaning performance of the detergent. They therefore start working in the actual washing step.
  • the formulations currently on the market consist of a pool of sequestrants and dispersants.
  • the sales format of these products is generally in bottles of variable volume (500-750ml) with dosing cap. Normally, 50-75ml of product is used per wash.
  • EP1679362A1 discloses a machine cleaner product in the form of a water-soluble single- or multi-compartment pouch comprising a limescale removing composition and a water-soluble enveloping material.
  • EP1690924A1 relates to a method of cleaning the interior surfaces of a non-loaded washing machine with a liquid composition, which comprises an acid system comprising formic acid and an acid forming a slightly water soluble calcium salt.
  • EP3202880A1 discloses a water-soluble unit dose article comprising a water-soluble film and a liquid laundry detergent composition.
  • liquid detergents sold in water-soluble single-dose capsules are known. However, they are unable to perform the functions of the aforementioned anti-scale, dishwasher care and washing machine care products and have so far been produced only in a monophasic version.
  • the product 1 is for the treatment of a dishwasher.
  • the product 1 is for the treatment of a washing machine.
  • the product 1 comprises a substantially water-soluble (in particular, biodegradable) casing 2; a collecting chamber 3, which is delimited by said casing 2; and an inner composition 4, which is substantially liquid, is arranged inside the collecting chamber 3 and comprises 10% to 95% (in particular to 90%) by weight with respect to the total weight of the inner composition 4, of an organic solvent and 0% to 20% by weight, with respect to the total weight of the inner composition 4, of water.
  • the inner composition 4 surprisingly has at least two phases (more in particular it is biphasic - as shown in the figures).
  • an air portion 5 (an air bubble), which tends to be arranged above the aforementioned first (upper) phase, is also arranged inside the chamber 3.
  • R 1 , R 2 and R 3 are linear.
  • C x -C y refers to a group and/or a compound which is intended as having x to y carbon atoms.
  • the inner composition 4 comprises (in particular, 1% to 40%; more in particular 5% to 25%; still more particularly, up to 20% by weight, with respect to the total weight of the inner composition 4 of) a further surfactant, which can be a mixture of different anionic surfactants and/or cationic surfactants and/or amphoteric surfactants or composed of a single anionic surfactant or a single cationic surfactant or a single amphoteric surfactant.
  • a further surfactant which can be a mixture of different anionic surfactants and/or cationic surfactants and/or amphoteric surfactants or composed of a single anionic surfactant or a single cationic surfactant or a single amphoteric surfactant.
  • the further surfactant is selected from the group consisting of: alkyl ethoxysulfates (in particular C 8 -C 38 ; more in particular, C 12 -C 28 ), alkyl sulfates (in particular C S -C 1S ; more in particular, C 12 -C 16 ), salts of the dodecylbenzenesulfonic acid, alkylbenzene sulfonates (in particular C 9 -C 27 ; more in particular, C 18 -C 24 ), alkyl sulfonates (in particular C 9 -C 21 ; more in particular, C 12 -C 18 ), soaps (in particular C 9 -C 21 ; more in particular, C 12 -C 18 ), amine ethoxylates (in particular C 12 -C 18 ), quaternary ammonium salts (in particular C 9 -C 21 ; more in particular, C 12 -C 18 ), betaines (in
  • sulfates and/or “sulfonates” of organic compounds refer to either the relative acids (sulfuric acids and sulphonic acids, respectively) or the relative salts (for example of sodium) and the anions (completely dissociated from the counterions).
  • alkylbenzene sulfonates have the following structural formula (I): wherein R 1 is a C 9 -C 18 aliphatic (in particular, an alkyl); R 2 is a C 1 -C 4 (in particular, C 2 -C 3 , more in particular C 2 ) an aliphatic (in particular, an alkyl) . More precisely but not necessarily, R 1 is a linear aliphatic (in particular, an alkyl); R 2 is a linear aliphatic (in particular, an alkyl).
  • the inner composition 4 comprises 2% to 40% by weight, with respect to the total weight of the inner composition 4, of a weak acid.
  • the weak acid is arranged together with the organic solvent (in the lower part of chamber 3).
  • the weak acid can be a mixture of different carboxylic acids (with or without phosphoric acid) or composed of a single carboxylic acid.
  • the inner composition 4 comprises up (less than or equal) to 35% (in particular, to 30%; more in particular, to 15%) by weight, with respect to the total weight of the inner composition 4, of the aforesaid weak acid.
  • the inner composition 4 comprises from 5% (in particular, from 7%; more in particular, from 20%) to 40% (in particular, to 35%) by weight, with respect to the total weight of the inner composition 4, of said weak acid.
  • the organic solvent comprises (in particular, is) glycerin.
  • the inner composition 4 comprises up (less than or equal) to 35% (in particular, up to 25%; more in particular, up to 20%; still more particularly, up to 15%; still more particularly, up to 6%) by weight, with respect to the total weight of said inner composition 4, of the alkalinizing agent.
  • the polymer component is able to sequester calcium and magnesium and, by acting synergistically with the weak acid, allows to reduce scale.
  • the polymer component comprises polymers with a mean molecular weight ranging from 1000 g/mol (in particular, from 3000 g/mol) to 20000 g/mol (in particular, to 10000 g/mol; more in particular, to 6000 g/mol).
  • the mean molecular weight of the polymers is measured through static light scattering methods (such as for example described in ASTM D4001 - 13).
  • the product 1 has a pH ranging from 2 to 7.
  • the inner composition 4 has a pH up to 4 (in particular, up to 3; more in particular, up to 2.5).
  • the inner composition 4 has a pH ranging from 3 (in particular, from 6) up to 7 (in particular, up to 6.7).
  • the casing 2 is (mainly) of polyvinyl alcohol (PVOH).
  • the casing 2 is floppy.
  • the casing 2 has a different shape when it is full (i.e., when the collecting chamber 3 is full) and when it is empty (i.e., when the collecting chamber 3 is empty).
  • the casing 2 when full, assumes an expanded shape that is different (and volumetrically greater) than the shape assumed by the same empty casing 2.
  • the product 1 has several advantages with respect to the state of the art. Among these we mention the following: surprisingly, it has been possible to obtain a biphasic inner composition 4; the product 1 has a reduced environmental impact (in particular, the casing 2, being water-soluble and biodegradable, leaves no residues); it is easy to dose; it allows to improve the activity of the detergents relatively to some types of dirt; to be used and, therefore, to make explicit its function it requires reduced energy, water, and time.
  • the casing 2 being water-soluble and biodegradable, leaves no residues
  • At least one aforesaid object is present inside the appliance.
  • the use provides that the product and a (further) detergent is used during the same washing cycle (in particular, during which at least one aforesaid object - more in particular, a plurality of said objects - is present inside the appliance).
  • the washing cycle comprises the aforementioned treatment step and (optionally) a washing step, during which the detergent is used to wash the object(s).
  • the washing step takes place at a higher temperature than the treatment step.
  • a discharge step during which the water used during the treatment step is removed (from the aforementioned appliance).
  • the product 1 can be placed, for example, in the cutlery basket and, considering the fast dissolution of the film, it starts working already in the pre-rinsing step (which in practice, corresponds to the aforementioned treatment step) allowing the dishwasher to be cleaned in preparation for washing.
  • the product containing the composition with formulation A was mainly prepared as a dishwasher care product. This product is presented as biphasic.
  • the product containing the composition with formulation C was mainly prepared as an anti-scale product for washing machines. This product is presented as biphasic.
  • the product containing the composition with formulation D was mainly prepared as an anti-scale product for washing machine. This product is presented as biphasic.
  • This example describes the comparison between the capability of removing dirt from cotton patches of the detergent Dixan ® alone (a detergent sold in Italy by Henkel ® and marketed in other countries under the names Persil ® , Wipp ® and LeChat ® ) compared to the combination of the detergent Dixan ® together with a single product in accordance with the present invention (the product with formulation D of the previous example).
  • the measurements of the treated cotton patches were carried out using a Dr Lange LUCI 100 reflectometer by measuring the light reflected by the stains for the assessment of the dirt removal. Differences of less than 2 optical points are not perceived by the human eye and therefore were not considered as significant.
  • This example describes the comparison of the dirt removal capability of the combination of the detergent Dixan ® together with a single product in accordance with the present invention (the product with formulation D of example 1) compared to the use of the detergent Dixan ® together with another anti-scale product already present on the market.
  • test was carried out without using any product.
  • the other test was carried out using a product in accordance with the invention (the product with formulation A of example 1).
