Definitions

  • the present invention relates to a solid toilet block. It is comprised in the technical field of detergent and/or perfuming and/or sanitizing products, in the solid form, to be applied onto the internal wall of sanitary appliances such as toilet bowls, bidet, washbasins, pissoirs.
  • Said blocks are capable to provide an effective cleansing, disinfecting and/or perfuming treatment of the toilet bowl, thanks to the use of a solid block, containing the various active ingredients of interest, slowly dissolving to rinsing water flushing.
  • the solid blocks are, in general, a product particularly attractive from a point of view of lasting in time, thanks to the presence of components which, adjusting the dissolution, allow a gradual and slow release of the various components constituting the block itself. Moreover, they are particularly interesting as they combine a long lasting, with production and marketing costs absolutely advantageous with respect to other similar products.
  • the formulations of the toilet blocks according to the state of the art usually contain, additional to surfactants and to minor components such as perfume, colorants, possible whiteners based on oxygen or chlorine, also significant amounts of inert fillers, which are usually inorganic fillers such as sodium sulfate or sodium carbonate.
  • the fillers have the purpose both to modulate consumption, and to give the proper texture to the formulation, allowing to adjust the amount of the total active components.
  • the weight of the solid block thus formulated is mostly due to the presence of high quantities of filler itself, with a considerable increase of costs to move an inert product during the transportation of the finished toilet block, with a consequent increase of production of CO 2 per piece.
  • the main purpose of the present invention is therefore that of finding a solid toilet block which ensures, at the same time, a particular combination of features and specifically: a plurality of actions, an aesthetic aspect particularly appealing for the consumer, a long lasting for a high number of flushing operations, without release of residual elements attaching to the walls of the sanitary object during use, and that it can be achieved through extremely simple methods.
  • the purpose of the present invention is therefore that of identifying a solid toilet block which, when applied onto the sanitary object and subjected to contact with rinsing water, gets and maintains a transparent appearance, with an unquestionable aesthetic advantage for the consumer.
  • a purpose of the present invention is also that of achieving a solid toilet block which, along with optimal appearance and lasting, presents an improved formulation allowing a plurality of actions and avoid formation of residues due to re-crystallization of fillers on the walls of the sanitary object during use.
  • Subject-matter of the present invention is a toilet block having a formulation comprising
  • a further purpose of the present invention is a method of production of the toilet block providing the production of the block by extrusion, molding or melting and/or pouring of mixture of components constituting said solid toilet block.
  • the present invention relates also to a device for the cleansing/sanitizing/perfuming of the toilet bowl suitable for hanging onto the edge of the bowl by means of a support for the toilet block subject-matter of the present invention.
  • Said support can be composed of a hook directly applied onto the toilet block, of a plastic cage or other similar solution.
  • the toilet block according to the present invention comprises as main component a non-ionic surfactant in an amount ranging from 85 to 95%, preferably from 91 to 93%, by weight with respect to the total weight of the block.
  • the non-ionic surfactant is a mixture of polyalkylethers, with a linear alkyl chain having a number of carbon atoms comprised between 12 and 22 and having a number of moles of ethylene per molecule greater than 30.
  • it is a mixture of oleyl and cetyl alcohols ethoxylates 55 moles EO in an amount ranging from 91 to 93%, more preferably from 91 to 92% by weight with respect to the total weight of the block.
  • the perfuming agent is present, in the toilet block according to the present invention, in an amount ranging from 2 to 10%, preferably from 3 to 5%, and still more preferably it is equal to 4% by weight with respect to the total weight of the block.
  • a perfuming agent can have a natural or synthetic origin.
  • the polyalcohol is preferred with respect to polyether and it is preferably selected from glycerol, ethylene glycol and propylene glycol, in an amount ranging from 0,1 to 3%, preferably from 1,5 to 2,5%, by weight with respect to the total weight of the block.
  • the glycerol can be glycerol of natural, synthetic or semi-synthetic origin.
  • the polyether is preferably a polyethylenglycol liquid at room temperature (20-25°C).
  • a foaming agent is also present, selected from anionic and/or non-ionic and/or cationic and/or amphoteric surfactants, preferably laurylether sodium sulfate (or sodium les 2 EO), said agent being present in an amount ranging from 1 to 3%, preferably from 1,5 to 2,5%, still more preferably equal to 2% by weight with respect to the total weight of the block.
  • the own specific non-ionic surfactants of the toilet block according to the present invention confer a good foaminess to the composition, obtaining a good cleansing effect and a good foam profile, without damaging the gel structure.
  • the filler when present, is selected from an inorganic filler, such as for example silica, salts of alkali and/or alkaline-earth metals, clays and/or zeolites, or an organic filler, both in the form of salt and in the molecular form, such as for example sucrose and/or xylitol.
  • an inorganic filler such as for example silica, salts of alkali and/or alkaline-earth metals, clays and/or zeolites, or an organic filler, both in the form of salt and in the molecular form, such as for example sucrose and/or xylitol.
  • Said filler being preferably an inorganic filler such as sodium sulfate or sodium carbonate.
  • the formulation of the toilet block according to the present invention can also provide, as minority components, colorants with the objective to confer a more pleasing appearance to the block, and/or preservatives and/or sanitizing agents, selected from those commonly known to the skilled person in the art.
  • the solid block according to the present invention preferably provides the following formulation consisting of oleyl or cetyl alcohols ethoxylates 55 moles EO; a perfuming agent; glycerol; sodium lauryl ether sulfate; colorant; water.
  • the solid block according to the present invention consists of 91,75% by weight of mixture of oleyl and cetyl alcohols ethoxylates 55 moles, 4% by weight of perfuming agent, 2% by weight of sodium les 2 EO (sliding pasta at 70%), 2% by weight of glycerol, 0.008% by weight of colorant and 0.242% by weight of water. The percentages are all percentages by weight with respect to the total weight of the solid block.
  • a main advantage of the solid toilet block according to the present invention is connected with the special formulation thereof which, with a much reduced content of filler or filler-free, allows to achieve a block with a weight of about 30 g, a number of flushing operations at least 20% greater than a block with a weight of 35-40 g of the state of the art.
  • a further advantage of the solid block according to the present invention is connected with the easiness of production thereof: indeed, it can be obtained through whichever known method for the achievement of a solid block, as for example extrusion, moulding, melting and subsequent pouring, substantially obtaining whichever form.
  • the solid toilet block thus achieved modifies and, by hydration, turns into a gel.
  • the toilet block swells by adsorbing water (documented by the increase of weight in the first few days), thus making the active components pre-dissolved and available.
  • the toilet block according to the present invention presents a particular formulation that ensures at the same time a slow dissolution, hydration to form the gel and pre-dissolution of active components that are so readily available.
  • the preferred process for preparing a solid toilet block according to the present invention comprises the following phases:
  • the moulding of the block may occur directly about such a hook, which results thus inserted into the structure of the same solid block.
  • extrusion In the case of extrusion, it can be carried out through a proper head of extrusion allowing to achieve the seat for the same hook.
  • the toilet block according to the present invention can be thus applied at a peripheral edge of a sanitary bowl or WC through a hook directly inserted in the same body of the block or through an application device outside the block, as a plastic cage.
  • the process for the production of the solid block according to the present invention presents the advantage to be extremely simplified, not requiring the preparation, separately, of a solid phase and of a gel phase which will be then necessarily joined in the end product, but, on the contrary, allows the achievement of the solid block with a single simple process.
  • the block turns into a product presenting on the surface initially a solid phase and a gel phase, to lead then, after a certain number of flushing operations, to be a solid block in the gel form.
  • the solid block according to the present invention implies costs definitely lower than those characterizing solid blocks comprising a gel phase according to the state of the art.
  • Such active components which are detergent, sanitizing or perfuming, dissolve in the water flow or evaporate and achieve the cleansing, sanitization and perfuming of the sanitary object.
  • the water also forms a foam, which increases the effectiveness of the cleansing of the sanitary object, causing the wear of the block, consuming at each flushing operation a small amount of materials, constituting the block itself, allowing therefore also the diffusion of a new perfuming agent. Therefore, as previously outlined, the standard blocks, during their life time, consume by erosion without substantially modifying their aspect.
  • the solid toilet block provided with the specific formulation according to the present invention has, instead, as peculiar feature that of changing appearance (from solid to transparent gel) during its use (see figures 1-3 , wherein it is apparent that the product in the initial state is matt ( figure 1 ), after a certain number of flushing operations (25 flushings), the product provides a solid matt phase and a transparent gel phase ( figure 2 ) and after a greater number of flushing operations (50 flushings) the product is fully in the gel form, transparent ( figure 3 ).
  • This change of physical appearance has two important functions: the first, further than aesthetic, is that of visually informing the consumer on the fact that the block is suitably functioning, hydrating and releasing active components.
  • the second relates to the fact that the gel forms by adsorption of water by side of the matrix, generating in fact a weight and volume increase in the initial phases of the solid block life.
  • This feature of the block according to the present invention is particularly important, as while a standard block having a weight of 35-40 g averagely lasts 150-200 flushing operations, the present block allows, in view of an initial amount of active components in the solid block equal to about 30g, to achieve an end product in gel which lasts at least 400 flushing operations.
  • a solid block according to the present invention subjected to rinsing operations of a volume variable from 6 to 9 litres each, having a weight of about 30 g, is completely rinsed off only after about 400 flushing operations, keeping in mind that the number of flushing operations necessary for the complete rinsing off depends also on the geometry of the block and the modes of flushing of water into the toilet bowl.
  • Such a block, in a plastic cage, has been arranged in a sanitary object and subjected to a flushing test which averagely provides about 15 flushing operations a day. During use, said tablet got hydrated, adsorbing the flushing water and becoming a transparent gel.
  • each line of the graph represents a solid toilet block according to the formulation as previously indicated in use in several models of toilet bowls and the dotted line represents the average consumption, from the initial point 0, with 100 as a weight, it was recorded a weight increase of the block until 150 flushing operations. Such a weight increase, due to hydration, has been recorded concurrently to the formation of the gel.
  • Example 2 comparative.
  • Such a block, in a plastic cage, has been arranged in a sanitary object and subjected to the same flushing test of example 1.
  • each line of the graph represents a solid toilet block according to the formulation previously indicated, in use in several models of toilet bowls, and the dotted line represents the average consumption.
  • Such a block, in a plastic cage, has been arranged in a sanitary object and subjected to the same flushing test of example 1.
