Definitions

  • the present invention relates to a toilet detergent unit, a toilet cleaning device having a detergent unit and a method of manufacturing a detergent unit.
  • This type of block is very popular with consumers.
  • the presence of two phases makes it possible to obtain an aesthetic appearance of this block, to which the consumers bring a great importance in their choice of detergent block.
  • the gel may have a translucent appearance highly appreciated by consumers.
  • the method of manufacturing such a detergent block is relatively long and complex. Indeed, in a first step, the solid phase, which generally forms the outer portion of the block, is extruded. This produces a long solid phase tube inside which is formed a hollow housing. This housing is then filled with the previously heated gel phase to make it liquid. The gel phase is then allowed to cool. The solid phase tube filled with gel phase is then cut to form a plurality of detergent blocks.
  • this process limits the forms that can be given to the gel phase of the detergent block.
  • the object of the present invention is to provide a method of manufacturing a detergent block does not have the aforementioned drawbacks.
  • the object of the invention is to provide a detergent block that is more easily achievable than the existing blocks and having the same aesthetic aspects appreciated by consumers, as well as a perfuming and cleaning power at least identical to the blocks comprising a gel phase and a solid phase.
  • the present invention provides a toilet detergent unit having two solid phases, one of the solid phases containing soap.
  • the invention also relates to a toilet cleaning device adapted to be suspended in a toilet by means of a suspension hook, comprising a detergent unit as described above in all its combinations.
  • a detergent unit as described above in all its combinations.
  • the detergent unit is directly attached to the hanger.
  • the invention also relates to a method of manufacturing a detergent block as described above in all its combinations, by coextrusion of the two solid phases.
  • a detergent unit 10 comprises two solid phases 12, 14. This detergent unit is more particularly intended to be suspended in the toilet bowl to be activated by toilet flush water, when this water flows on the detergent block.
  • the first solid phase 12 is a conventional solid phase of detergent block.
  • This solid phase may further include a foam booster, anti-lime products.
  • the foam booster increases the amount of foam produced when the hunt is pulled.
  • This first phase can represent between 75 and 95% by weight of the total weight of the detergent block 10.
  • the second solid phase 14 contains soap. This second phase represents between 5 and 25% by weight of the weight of the detergent block 10, preferably between 8 and 17% by weight.
  • This second phase may also include blocking aid products, such as PEG or the like, the solvent, such as glycerin, and perfuming products.
  • the perfuming products are indeed mixed, preferably with soap which has a lower solubility than the first solid phase. The perfuming power of the detergent unit is thus ensured until the end of its use.
  • This second solid phase 14 may also comprise coloring agents and / or liquids.
  • liquids added to the solid phase containing soap 14 are in the first place perfuming products. However, they may also be manufacturing aids or additives to improve the transparency or solubility of the solid phase containing soap 14.
  • the second solid phase preferably contains a translucent soap, to obtain an aesthetic appearance very close to the gel phase blocks.
  • the mass of translucent soap advantageously represents from 80 to 100%, preferably from 90 to 95% by weight, of the weight of the solid phase containing the soap 14.
  • the perfuming products present in the second solid phase containing soap are highly concentrated. More precisely, the odorants represent between 85 and 100% of the composition of these perfuming products, which preferably do not contain any solvent. This makes it possible to reduce the amount of liquid added to the solid phase containing soap 14 and thus facilitates the manufacture of the detergent unit, while ensuring the strength of the perfume and the odor-controlling power of the detergent unit.
  • the odorous substances may in particular be of natural or synthetic origin. These fragrant substances of natural or synthetic origin can also be combined.
  • the second solid phase 14 preferably comprises between 5 and 20% by weight, preferably between 8 and 12%, by weight of perfuming products.
  • the soap contained in the second solid phase 14 can for example be obtained by the following method. At first, soap granules, widely used on the market, are mixed with additives. The mass of the additives preferably does not represent more than 7% by weight of the mass of finally obtained soap. Then, this assembly is refined by means of refining screen. Finally, the soap is extruded in a cylindrical form.
  • soap transparency is an important element in achieving the aesthetic effect sought by consumers. It has been found that the best transparency effects are obtained with soaps based on plants or with vegetable oil (s).
  • Another important element for the transparency of the soap is the presence of certain additives, such as sorbitol or glycerine, which prevent the crystallization process of the soap, a soap with a crystalline structure being opaque.
  • the soap used preferably has good solubility in water. It has been found that soaps obtained by saponification of tallow, palm oil or a mixture of tallow and palm oil have a solubility well suited to the application.
  • the soap in water may contain potassium salt of fatty acid.
  • the two phases 12 and 14 can take any desired form.
  • the second solid phase 14 comprises a cylindrical portion 16 of circular base in the center of the detergent unit 10, also cylindrical with a circular base.
  • the second solid phase 14 also comprises eight cylindrical portions 18 whose base is elliptical.
  • the solid phase containing soap 14 is made in the form of several pieces, that is to say that this solid phase containing soap 14 is not monobloc in the detergent block 10. On thus increases the contact area of the second solid phase containing soap with the surrounding medium for the same mass of this second phase. This improves both the solubility of the soap when the hunt is drawn. In addition, the same results in greater evaporation of perfumes mixed with soap, which ensures a better perfuming power of the detergent block.
  • the volume area of the soap-containing solid phase - i.e., the area of the volume formed by the entire second solid phase containing soap - is between 150 and 300%, preferably between 200 and 250 %, of the surface of the solid phase containing soap if the solid phase containing soap was made in the form of a solid one-piece cylinder.
  • the second solid phase may take the form of a plurality of cylinders extending the entire length of the detergent block, or nuggets or balls distributed in the first classical solid phase.
  • these pieces of the second solid phase containing soap preferably contain between 80 and 100% by weight, preferably between 90 and 95%, of soap, preferably translucent.
  • These pieces furthermore comprise, in a preferred manner, a perfuming product.
  • these pieces of the second solid phase containing soap, or the second phase containing soap, whatever its shape are distributed in the detergent unit, outside a central volume in the form of a cylinder. . In other words, they are distributed in a ring-shaped volume at the periphery of the detergent unit 10.
  • the detergent unit is adapted to be implemented in a toilet cleaning device, adapted to be suspended in the toilet bowl by means of a hanger.
  • the hook is fixed integrally to the detergent unit 10, that is to say that the detergent unit and the hook forms a one-piece assembly.
  • the flush water flows over the detergent block.
  • the flushing water takes care of the detergent products in the block and cleans the toilet bowl.
  • the water is charged soap present in the solid phase containing soap.
  • the water then forms a foam that increases the efficiency of cleaning the toilet bowl.
  • the water causes wear of the block on the surface. In other words, a small part of the block, previously in contact with the surrounding environment, is driven by the flushing water. The part of the block in contact with the environment surrounding the block is thus replaced. This causes the release of perfuming products now in contact with the environment surrounding the detergent block.
  • composition of the detergent unit 10 Three examples of the composition of the detergent unit 10 are given below.
  • the detergent block weighs 45g.
  • the first solid phase 12 conventional weighs 38g while the solid phase containing soap weighs 7g.
  • the first conventional solid phase weighs 40 g and the second solid phase weighs 5 g.
  • the first conventional solid phase weighs 35 g while the phase comprising soap weighs 10 g.
  • Table I groups together the composition of the first conventional solid phase of Examples 1, 2 and 3, whereas Table II groups together the composition of the solid phases containing soap of these three examples.
  • Table 1 composition of the first classical solid phase of Examples 1, 2 and 3 ⁇ / u> Product
  • Example 1 Example 2
  • Example 3 Benzene alkyl sulfonate 20-30 10-20 10-20 Alpha olefin sulphonate 10-20 20-30 20-30 Sodium sulphate 15-25 20-25 20-25 Sodium carbonate 20-25 15-25 15-25 Perfume 3-8 3-8 3-8 Sodium phosphonate 1-3 1-3 1-3 SLES (70%) 1-4 1-4 1-4 Silica 0.5-6 0.5-6 Titanium dioxide 0.5-2 0.5-2 0.5-2 products
  • Example 1 Example 2
  • compositions 1, 2 and 3 allowed easy manufacture of the detergent block by coextrusion.
  • the blocks thus obtained showed good performance both in terms of cleaning the toilet and the quality and effectiveness of their perfume.
  • the figure 2 illustrates the comparison of the perfume power of a composition block according to Example 1, with respect to a gel phase block comprising 30% by weight of perfuming products.
  • the dashed blocks represent the power of the scent of the blocks initially, before the first flush, while the blocks in solid lines represent the power of the perfume of the blocks after 22 hunts.
  • the intensity of the perfume of the blocks is represented in ordinate, this intensity being noted between 0 and 5. This intensity corresponds to an average score given by a panel of 15 experts.
  • Block 10 of composition according to Example 1 showed not only a better initial perfuming power (shown in dotted lines on the figure 2 ), but also a better durability of this perfuming power. Thus, after 22 flushes, the perfuming power of the composition block according to Example 1 is always better than the perfuming power of the gel phase block comprising 30% by weight of perfuming products.
  • the detergent unit 10 can easily be made by coextrusion of the two solid phases 12, 14, as illustrated in FIG. figure 3 . Indeed, these two phases 12, 14 are solid at room temperature.
  • the method of manufacturing the detergent unit 10 by coextrusion no longer includes a step of waiting for the cooling of one of the two phases .
  • This represents a significant time saving, which results in a detergent unit manufacturing cost less than the cost of manufacturing a detergent unit comprising a gel phase.
  • the advantages of the detergent unit 10 are numerous.
  • the detergent unit 10 consisting of two solid phases, is easier to handle.
  • the detergent block 10 does not leave traces in the toilet bowl as can be commonly found in the case of liquid detergent and perfuming products.
  • the cost price of the detergent unit 10 is less than the cost price of a block comprising a gel phase manufactured according to the conventional method described in the introduction.
