Definitions

  • the present invention relates to a perfuming and/or detergent gel tablet, preferably for WC applications.
  • Most tablets for WCs are based on a solid matrix.
  • This matrix has a composition based on anionic surfactants and, in a smaller quantity, non-ionic surfactants on a support of an inorganic salt: sodium carbonate and/or sodium sulfate and/or less frequently sodium chloride.
  • Other additives such as, for example, polyethyleneglycols, can also be present in the composition, which modulate the hardness and mechanical properties of the composition and its behaviour in the extrusion process, and other ingredients such as dyes, fragrances, etc.
  • compositions in the form of gels or liquids. These compositions are also based on surfactants (anionic, non-ionic, amphoteric) and contain considerable quantities of water (30-75% by weight with respect to the total weight of the composition).
  • surfactants anionic, non-ionic, amphoteric
  • the structure of gels typically derives from the type and quantity of the surfactants, but also from further components: polyacrylates, cellulose, rheology modifiers, etc.
  • the quantity of water in the composition significantly influences the physical properties of compositions in gel form such as, for example, the viscosity, the melting point or the temperature at which phase changes take place inside the structure. If not stored in a closed container, these compositions in gel form tend to gradually lose water and undergo profound physical changes during their useful life, a problem which, as already mentioned, does not arise in the case of solid tablets.
  • gels based on surfactants and for detergence applications are known in literature: see US 2011/0268683 or also EP 0 598 335 A2 . These gels are in fact water-based and the concentration of water influences their physical properties such as viscosity, melting point or the temperature at which phase changes take place inside the structure, etc.
  • a typical example relates to products in which the gel tablet is used as a sanitizing and/or cleaning and/or perfuming element in a WC cage, which evidently requires numerous openings.
  • the use of a gel tablet in cage containers, in place of traditional solid tablets with a high content of inert products (such as sodium carbonate, calcium carbonate, sodium sulfate), has undoubted and evident advantages: it is in fact possible to combine a form of gel product, with aesthetics and perfuming performances definitely superior to traditional tablets, with a mode of use in cages.
  • a product for WCs composed of a tablet in a cage is typically marketed in blisters of thermoformed plastic material which allow the shelf contents to be viewed. These blisters are closed on the back with a welded plastic film or with cardboard, also applied by welding or gluing. As an alternative, these products in cages are marketed in flowpacks of plastic material, in turn closed in cartons.
  • An objective of the present invention is therefore to identify a gel tablet that overcomes the drawbacks of the gel tablets of the state of the art.
  • a further objective of the present invention is to identify a table in gel form which can be used in open-cage applications, preferably for WCs.
  • the object of the present invention relates to a perfuming and/or detergent gel tablet characterized in that it has
  • the melting or transition point is the temperature at which the composition in gel form becomes liquid and the product can therefore totally or partially come out of the cage containing it.
  • the initial melting or transition point from the gel state to the liquid state refers to the melting or transition point that characterizes the gel tablet having the initial composition, i.e. the composition in which no loss of water has occurred, due to use, with respect to the quantity of water present in the initial composition.
  • a gel tablet generally loses water in use, dehydrating and losing its initial gel structure, and consequently the second element that defines the gel tablet according to the present invention is particularly important as its specifies and requires as an essential feature that the gel tablet preserves a melting or transition point higher than or equal to 44°C, also when the gel tablet has reached a high dehydration degree (i.e. it has lost 75 to 95% by weight of water with respect to the initial quantity of water) due to use.
  • the perfuming and/or detergent gel tablet according to the present invention is therefore defined by two characteristics which, together, ensure that the product, during its useful life, always maintains its physical gel form, even as a result of the inevitable gradual loss of moisture during use.
  • This initial melting point or transition point value from the gel state to the liquid state within the range of 65°C to 90°C is also extremely convenient as it allows the tablet to be produced in gel form, operating with the composition in the liquid state, without causing damage to the product itself or to some of it components (for example the fragrance).
  • the melting or transition point is the temperature at which the composition in gel form becomes liquid and the product can therefore either totally or partially come out of the cage containing it.
  • the melting or transition point can be measured empirically through an aging test in an oven, which evaluates the stability of the product over time. For a more specific and accurate evaluation of this property, a portion of gel is transferred to a test-tube, a calibrated thermometer is inserted in said test-tube and the bottom of the test-tube is immersed in a hot water bath. When the gel becomes liquid the temperature of the transition state is read.
  • the measurement method used in the present patent application is the following: 10 g of composition are placed in a beaker having a diameter of 5 cm and a calibrated thermometer is inserted. Water is heated to a temperature of 40°C in a hot bath. The beaker is then immersed in the bath at 40°C and the temperature of the composition is read at the moment when the gel melts to become liquid.
  • This method is applied for measuring the melting or transition point of both the initial product that has not yet undergone any dehydration, and also the dehydrated product, i.e. which has lost from 75 to 95% by weight of water with respect to the initial quantity of water.
  • a further object of the present invention relates to the use of a gel tablet, as detergent and/or perfuming agent, by application through an open cage in sanitary appliances, household appliances, etc. preferably in WCs.
  • the polyvinilpyrrolidone polymer has a structuring/viscosifying function, which allows the integrity of the structure of the composition to be maintained in the gel phase during the life of the product, under stress and also at high temperatures, thus allowing a high-quality gel tablet to be formulated, together with the other components.
  • a preferred example of a gel tablet according to the present invention, which is particularly performing, has the following composition:
  • the main and surprising advantage of the gel tablet according to the present invention is that it maintains the physical gel state even after a substantial loss of moisture.
  • the insertion of cellulose and/or polyvinylpyrrolidone polymers, combined with specific ethoxylated alcohols surprisingly allows a clear improvement in terms of stability, allowing the phase transition to the liquid state to be avoided even in the face of significant water losses.
  • the gel tablets according to the present invention surprisingly maintain the physical gel form for much longer times, even after substantial moisture losses.
  • the phase transition from gel to the liquid state consequently takes place, under the same conditions, in much longer times with respect to the tablets of the state of the art, therefore resulting in an improved stability.
  • the gel tablet according to the present invention is also particularly advantageous in a condition of non-reception of water flows after application in the WC. Also under this condition of use, the presence of polyvinylpyrrolidone polymer leads to a greater general stability of the composition in terms of daily moisture loss and consequent removal, in terms of time, of the phase transition phenomenon to liquid.
  • the gel tablet according to the present invention also has the advantage of an improved stability also in the presence of strongly destabilizing agents such as foaming surfactants with a negative charge. Also in the presence of sodium lauryl sulfate, in fact, i.e. an anionic foaming surfactant, no decrease in the stability is observed. This allows the production of gel tablets having a sufficient stability and an increased foaming activity.
  • Some examples are provided of particularly advantageous blisters and sealing films (materials and thicknesses).
  • Coupled material PETalox/PET.EvOH.PE 30 microns (transparent metallized polyester with a further EvOH barrier)
  • the gel tablet was prepared as follows:
  • the gel tablets F3, F4 and F6 are tablets according to the present invention, whereas the tablets F1, F2, F5, F7, F8, F9 and F10 are tablets according to the state of the art or in any case not representative of the present invention. More specifically, the tablet F10 represents a compound according to the example of the document US 6,667,286 , corresponding to European patent EP1086199 .
  • composition F1 indicated in Table 1 has a melting point of 70°C.
  • the same composition F1 placed in a blister with sealing film PET/PE.EVOH.PE and a thermoformed PE/PET valve in an oven at 40°C has a phase transition to the liquid state at a temperature lower than 40°C after 5 weeks, having lost about 43.8% of water, as indicated in Table 2 hereunder.
  • the loss of water was measured by weighing the sample before the experiment and subtracting the weight measured from week to week, from the initial weight. The difference in weight between the initial weight and the weight per week 1 (2, 3, 4 or 5) represents the moisture/water lost during the same week.
  • Table 2 The experiment was carried out at a fixed temperature of 40°C. F1 Week 1 Week 2 Week 3 Week 4 Week 5 Moisture loss percentage (Physical state) 9.3% (Gel) 18.8% (Gel) 26.1% (Gel) 34.4% (Gel) 43.8% (Liquid)
  • composition F2 has a better stability profile with respect to the composition F1.
  • the phase transition to the liquid state at 40°C is postponed by 5 weeks compared to F1, bringing the stability in blisters with PET/PE.EVOH.PE sealing film and thermoformed PE/PET valve, from 5 to 10 weeks. The effect is even more evident for F4 and F6.
  • the presence of cellulose (F2) or polyvinylpyrrolidone (F4 and F6) polymers in the gel tablet according to the present invention has in fact brought about a significant improvement.
  • the stability data of Table 3 show maintenance of the physical state of the gel for a longer time, as the moisture loss increases.
  • the gel tablet according to the present invention comprising cetyl stearyl ethoxylated alcohols with an ethoxylation degree of 20 EO combined with a polyvinylpyrrolidone polymer PVP-K90 (F4 and F6), maintains the physical gel state also after significant moisture losses.
  • the insertion of the polyvinylpyrrolidone polymer PVP-K90 surprisingly produces an evident improvement in terms of stability.
  • the stability profile in fact, is further improved bringing the phase transition to the liquid state to the thirteenth week.
  • Table 3 above also shows an improved stability profile also for compositions, such as the composition F6, in which a strongly destabilizing agent is present, such as foaming surfactants with a negative charge.
  • composition F6 also comprising sodium lauryl sulfate, i.e. an anionic foaming surfactant, does not show a decrease in the stability: the phase transition to the liquid state of F6 becomes evident at the tenth week, with a definite improvement with respect to F1, a composition that does not include either polyvinylpyrrolidone polymers or cellulose polymers, and also with respect, for example, to F2, a composition in which the polymer is a cellulose polymer and does not contain however the destabilizing agent.
  • sodium lauryl sulfate i.e. an anionic foaming surfactant
  • composition F9 (i.e. the same composition as F6, but without the polymer PVP-K90) incorporates the concept of modification of the composition without the stabilizing agent PVP-K90.
  • the data indicated in Table 3 show an improvement in terms of stability, bringing the phase transition from gel to liquid from 81.7% for a composition F6 with PVP-K90, to 70.1% of moisture loss for a composition F9 without PVP-K90, the anionic surfactant being present in both cases.
  • composition F4 showed the above-mentioned phenomenon on the sixth day of application without use, whereas the formulation F5 showed the same phase transition on the second day of application.
  • figure 1 shows the formulation F5 which undergoes destructuring after 2 days under a condition of non-reception of water flows.
  • Example 1 As further evidence of what is shown in Example 1 and in Table 3, a stability test method was developed, with the aim of ascertaining, in an accelerated way, the outcome of the stability tests, and the following surprising results, indicated in Table 4, were obtained.
  • the method provides for the positioning of a cage in an open Doypack made of PET/AL/PE material with a fixed dimension of the opening and kept at 40°C (represented in Figure 2 ).
  • the formulations F2, F3, F4 show maintenance of the physical gel state, for a greater number of days with respect to the formulations of the state of the art F1 and F7.
  • composition F7 are of particular interest, where it is shown that not all the classes of polymers allow the technical problem addressed by the present invention to be solved, i.e. obtaining an improved stability over time.
  • compositions F3 and F4 with polyvinylpyrrolidone polymers with respect to the formulation F7 with a polymer such as xanthan gum.
  • Table 5 the compositions were kept at a fixed temperature of 50°C.
  • Formulation Day 2 Day 4 Day 6 Day 8 Day 10 Day 12 Day 13 F1 Gel Gel Liquid F2 Gel Gel Gel Gel Gel Gel Liquid F3 Gel Gel Gel Gel Gel Gel Liquid F4 Gel Gel Gel Gel Gel Gel Gel Gel Gel Liquid F5 Gel Gel Gel Gel Gel Liquid F6 Gel Gel Gel Gel Gel Gel Liquid F7 Gel Gel Gel Gel Gel Gel Liquid F8 Gel Gel Gel Gel Gel Gel Gel Gel Gel Liquid F10 Liquid
  • formulations according to the state of the art i.e. without cellulose or polyvinylpyrrolidone polymer, F1 and F5, provide less performing results in terms of water loss percentage and therefore stability over time with respect to the composition F4 with PVP polymer.
  • the tablet F10 represents a compound according to the example of the document US 6,667,286 , having the formulation indicated in Table 1: when subjected to the test described above, and specifically Zipper Albal of PE-LD material at 50°C continuously over time, it begins to show destructuring of the gel already after a day of storage and with a much lower water loss, equal to 7.15% of the total water present in the composition.
  • Table 6 also shows that the composition F5 according to the state of the art, although comprising the same cetyl stearyl ethoxylated alcohol with an ethoxylation degree of 20 EO, is however less stable with respect to the composition F4 in which said alcohol is present in a combination with polyvinylpyrrolidone polymer. This demonstrates the synergistic effect associated with the presence of both components.
  • Table 6 the compositions were kept at a fixed temperature of 50°C.
  • the test with the product Duck Fresh Discs was carried out under conditions completely comparable with the conditions used and indicated above for the formulations F1, F4 and F5, placing a weight of 27 grams of product in a cage, subsequently positioned in a sachet of PE-LD material having a thickness of 65 ⁇ m with the possibility of closing with a front zip (Zipper Albal Sacs multi-usages) and kept at 50°C.
  • the gel undergoes phase transition passing from the liquid state at the eighth day in an oven at 50°C, with a moisture loss of 59.7%.
  • This test is therefore a further confirmation of the superior and surprising results of the formulations according to the present invention.
  • the graph of figure 4 shows the rheological profile through an oscillatory test, rheometer Modular Compact Rheometer MCR102, of the composition F6 of Table 1 and the product Duck Fresh Discs previously mentioned.
  • This test is independent of the weight of the product and is an objective test that demonstrates that, in the case of the tablet according to the present invention, more energy is required for effecting the phase inversion.
  • the graph shows, in fact, that, with the same moisture loss, there is an inversion of the elastic module to viscous (flow point) at a temperature higher than F6 with respect to the other composition. This therefore confirms that, with the same conditions, the loss of structure and therefore the transition to the liquid state takes place for the composition F6 (black line) at 75°C and for the Duck composition (grey line) at 51°C, further confirming the greater stability of the structure guaranteed by the use of the PVP polymers according to the present invention.
  • composition F4 showed a significantly improved stability with respect to the composition F8 as indicated in Table 7, re-confirming the better performances of the PVP polymer according to the invention present in the composition F4, with respect to the xanthan gum present in the composition F8.
  • Table 7 the compositions were kept at the same fixed temperature of 50°C.
  • Composition F4 F8 Moisture loss with transition to the liquid state 91.2% 78.5%
  • the datum indicated in Table 7 is particularly relevant.
  • the storage conditions in fact, specifically studied for the present method, are characterized by being particularly stressed conditions to be able to obtain a stability result in rapid time.
  • composition F8 The result in terms of percentage of moisture loss relating to the composition F8 is of particular interest, wherein the polyvinylpyrrolidone polymer has been replaced by xanthan gum.
  • the formulation F8 When subjected to the test described in Example 3, i.e. in Zipper Albal of PE-LD material at 50°C continuously over time, the formulation F8, very similar to the preferred formulation F4 from which it differs only in the substitution of polyvinylpyrrolidone with xanthan gum, in any case shows a considerable deterioration in the performances (see Table 7 above).
  • compositions F3 and F4 according to the present invention compared with the compositions F1 and F5, without polymers, surprisingly maintained a rigid gel structure for a greater number of weeks.
  • Table 8 the compositions were kept at a fixed temperature of 60°C.
  • the stability over time evaluated as the capacity of maintaining a rigid structure with an increasing moisture loss of the gel, is unequivocally correlated with the presence of PVP or cellulose polymers within the gel tablet formulation and, in particular, is maximum when the polymer is polyvinylpyrrolidone with a molecular weigth (g/mol) ranging from 900,000 a 1,500,000 (PVP K90).
  • the structure of the gel can vary greatly.
  • an ethoxylation number ranging from 10 EO to 20 EO the phase transition to the liquid state already takes place at a temperature lower than 40 degrees whereas with an ethoxylation number ranging from 20 EO to 80 EO, the stability of the gel is always maintained, at a temperature of 40 degrees.
  • the carbon atoms of the aliphatic chain of the non-ionic surfactant there is a consequent variation in the physico-chemical characteristics of the gel.
  • Aliphatic chains having an overall length of C16-C18 maintain a good stability at a temperature of 40 degrees
  • aliphatic chains having an overall length of C12-C14 already have a transition to the liquid state at 40 degrees.
  • the tests presented in the examples according to the present invention demonstrate how the choice of the specific polymer is essential, as polymers such as xanthan gum and polymers of the polyvinylpyrrolidone type having a lower molecular weight such as, for example, PVP K30, although allowing a certain advantage in terms of stability with respect to the complete absence of polymer, have problems of another nature however, that do not allow them to be considered as a suitable solution for solving the technical problem according to the present invention. More specifically, for example, the use of PVP K30 in the compositions previously described, leads to a persistent, aesthetically unacceptable flocculation at the end of processing.
  • Polymers such as xanthan gum lead to a lowering of the level of foam produced inside the WC, such as to reduce the cleaning and sanitizing performances.
  • xanthan gum lead to a lowering of the level of foam produced inside the WC, such as to reduce the cleaning and sanitizing performances.
