    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The present invention relates to a detergent for washing sportswear, which has three distinct phases compartmentalized by means of a water-soluble film so that when the detergent comes into contact with water, the film dissolves allowing the reaction between the detergent phases, causing a catalytic reaction that generates a percentage of active oxygen capable of oxidizing the molecules associated with the bad odors that emanate from the sportswear used.
    [0007]
    [0008] The detergent of the invention incorporates oxidizing agents capable of transforming the odor-responsible thiols into water-soluble sulfonates.
    [0009] Additionally, the detergent incorporates efficient disinfectant agents to eliminate the population of dermal bacteria present in cotton garments and other acrylic fibers, which are responsible for the biotransformation of the fundamental sweat molecule secreted by the armpit S- [1- (2 -hydroxyethyl) -1-methylbutyl] - (L) -cysteinylglycine or also called S-Cys-Gly-3M3SH, and that plays a demonstrated role in the bad smell when it is metabolized to free thioalcohol.
    [0010]
    [0011] Thus, the object of the invention is to provide a sustainable detergent with a high disinfectant and odor eliminating capacity.
    [0012]
    [0013] BACKGROUND OF THE INVENTION
    [0014]
    [0015] It is well known that in recent years sports practice among the population has increased knowing the great benefits it has for the human being. This leads to an increase in the purchase of sportswear.
    [0016]
    [0017] Certainly, users usually complain about the difficulties that lie in eliminating the smell of their sportswear generated by sweat. That is, a stumbling block is detected difficult to overcome for the elimination of bad smell when sportswear is washed with traditional detergents.
    [0018]
    [0019] The detergent of the present invention is intended to overcome these drawbacks.
    [0020]
    [0021] DESCRIPTION OF THE INVENTION
    [0022]
    [0023] The detergent that is recommended solves in a fully satisfactory way the problem described above, based on a product, preferably as a capsule, in which they differ, at least:
    [0024]
    [0025] - A catalyst phase composed of a chitosan powder support impregnated with a solution of manganese sulfate that acts as a catalyst for the reaction on contact with water,
    [0026] - A solid state peroxide phase, and
    [0027] - A phase of neutral soap type Marseille in solid state, preferably in the form of scales.
    [0028]
    [0029] The Marseille-type neutral soap phase contains an amount between 15 and 20 grams, the solid state sodium percarbonate phase contains between 0.5 and 2 grams, and the catalyst phase contains an amount between 0.5 and 1.25 grams. .
    [0030]
    [0031] More specifically, the detergent of the invention is made up of at least three compartments, where each is composed of a water-soluble film and separately contains each of the phases mentioned above.
    [0032]
    [0033] Thus, the compartments integrated by the soluble film are joined to generate a detergent capsule in which the phases that integrate it are differentiated. In this way, when the capsule comes into contact with water, the film of the compartments dissolves and the catalyst phase that generates the catalytic activity when in contact with the peroxide, releasing a high percentage of active oxygen that allows the transformation by oxidation of malodorous molecules. The contact of this medium with the soap already in liquid solution from the third compartment completes the washing of the garment.
    [0034] The object of the present invention is to provide a detergent for cleaning sportswear which are characterized by the emanation of a strong and persistent bad smell caused by the sweat that permeates the garment, generated by the athlete during sports.
    [0035]
    [0036] The catalyst phase has been synthesized by impregnation from natural biopolymers from chitosan, in addition to other biopolymers such as carrageenans and gelatins. Chitosan, formed in the deacetylation of chitin, and constituent of the exoskeleton of crustaceans and insects, is a polysaccharide whose monomer is glucosamine, one of the key points since it has the ability to adsorb and complex certain metal ions present in aqueous solutions due to the strong interaction with protonated amino groups of glucosamine units and metal ions.
    [0037]
    [0038] Specifically, the catalyst phase is prepared by wet impregnation, where the chitosan support comes into contact with the impregnating solution, a solution of manganese sulfate, for a certain time until the chitosan support is saturated with solution. After that time the excess liquid is removed by evaporation, obtaining the solid catalyst phase of the detergent object of the invention.
    [0039]
    [0040] Optionally, the manganese sulfate solution of the catalyst phase used to impregnate the chitosan support has a concentration percentage in a range of between 2% and 10%.
    [0041]
    [0042] The detergent manufacturing process for washing sportswear requires careful preparation of the catalyst phase, specifically, the stages that integrate the manufacturing process of the catalyst phase are as follows:
    [0043]
    [0044] - Preparation of a solution of manganese sulfate, with a preferred concentration of between 2% and 10%,
    [0045] - Preparation of a solution of chitosan in water at 9.1% concentration, - Stirring of the mixture of chitosan and water at a rate of at least 10 R.P.M.
    [0046] for at least 20 minutes and at a temperature between 70 ° C and 90 ° C,
    [0047] - Dropwise addition of the 5% manganese sulfate solution on the chitosan solution, maintaining the conditions of stirring and temperature to obtain a chitosan support impregnated with manganese sulfate where manganese forms a complex with the functional groups of chitosan,
    [0048] - Decrease in the temperature of the chitosan support impregnated with manganese sulfate up to 60 ° C while stirring is maintained and until the support obtained is dry resulting in the catalyst phase.
    [0049]
    [0050] Additionally, a phase of a solid state peroxide and a solid phase of Marseille-type natural soap is prepared.
    [0051]
    [0052] Optionally, the phase corresponding to peroxide could be constituted by sodium carbonate peroxyhydrate or also called sodium percarbonate.
    [0053]
    [0054] Each of the three phases prepared is introduced into three different compartments each delimited by a water soluble film. Finally, the compartments are joined to generate a detergent capsule.
    [0055]
    [0056] Advantageously, from the tests carried out which are detailed in the preferred embodiment section of the invention, it appears that the prepared samples have a high catalytic capacity that generates a remarkable percentage of active oxygen for the oxidation removal of thiol molecules to sulphonates. water soluble
    [0057]
    [0058] BRIEF DESCRIPTION OF THE DRAWINGS
    [0059]
    [0060] To complement the description that will then be made and in order to help a better understanding of the features of the invention, according to a preferred example of practical implementation thereof, a set of figures is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:
    [0061]
    [0062] Figure 1 shows a perspective view of the detergent capsule made in accordance with the object of the present invention.
    [0063] Figure 2.- Shows the representation of the curves obtained by gas chromatography - mass spectrometry at four different times (curves A, B, C and D) after contacting the detergent of the invention with the compound to be dissolved. in water
    [0064]
    [0065] PREFERRED EMBODIMENT OF THE INVENTION
    [0066]
    [0067] In view of Figure 1, an example of the presentation format of the developed invention can be seen, where the detergent capsule (5) is preferably integrated by three compartments where each independently stores each of the three phases: a phase that contains the catalyst (1), a phase that contains sodium percarbonate powder (2) and a third phase of Marseille-type natural soap (3).
    [0068]
    [0069] Preferably, the Marseille-type natural soap phase (3) contains an amount of 18 grams, the solid state sodium percarbonate phase (2) contains 1 gram and the catalyst phase (1) contains 0.75 grams.
    [0070]
    [0071] Next, the preferred manufacturing process for the catalyst phase of the invention is detailed.
    [0072]
    [0073] In this regard, it should be noted that during the tests manganese sulfate solutions were prepared where concentrations of this salt were used in percentages of 2.5%, 5%, 7.5% and 10%.
    [0074]
    [0075] The tests showed that the optimal concentration of manganese sulfate concentration was 5%, achieving active oxygen formation times adequate to the washing process, with the minimum concentrations of Mn2 + in the system.
    [0076]
    [0077] In a beaker, 15 ml of distilled water is introduced and 40 mg of manganese sulfate (MnSO4) 5% of Manganese is added and stirred until completely dissolved.
    [0078]
    [0079] In another beaker, 10 ml of water and one gram of chitosan are introduced, this solution is kept under stirring at a temperature of 80 ° C.
    [0080] The manganese sulfate solution prepared above is taken and with a Pasteur pipette is added dropwise onto the solution of the prepared chitosan support while maintaining the stirring conditions at a temperature of 80 ° C.
    [0081]
    [0082] After the complete addition of the manganese sulfate solution prepared on the chitosan solution, the temperature is lowered to 60 ° C and gentle stirring is continued until the prepared material is dry.
    [0083]
    [0084] Once the material is dry, stirring and heating are stopped, resulting in a chitosan support completely impregnated with a manganese solution forming a complex between both species.
    [0085]
    [0086] The samples prepared from the catalyst phase are then reproduced (chitosan supports impregnated with a solution of manganese sulfate):
    [0087]
    [0088]
    [0089]
    [0090]
    [0091] In order to verify the catalytic activity of the prepared material samples, the determination of the active oxygen generated in the reaction was made when coming into contact with soap and peroxide in an aqueous medium, for this purpose it was necessary to use an oxygen meter in air which is able to control the percentage of oxygen in the environment.
    [0092]
    [0093] The realization of this oxygen determination was carried out in a sealed atmosphere to avoid the interference of the oxygen present in the air and in order to obtain comparable results, to verify the catalytic activity of the prepared samples of the catalyst phase.
    [0094]
    [0095] The parameters used to demonstrate the catalytic capacity of the prepared samples have been the following:
    [0096] - 500 milliliters of distilled water,
    [0097] - 6.25 grams of solid natural Marseille soap,
    [0098] - 0.32 grams of sodium carbonate peroxyhydrate,
    [0099] - 0.25 grams of sample 1,2 and 3, to be analyzed,
    [0100] - Ambient temperature and stirring continues.
    [0101]
    [0102] The following table shows the measured values of percentage of oxygen at room temperature. These values have been measured at different times after the reaction of the catalyst phase with the other two phases, specifically the values were taken at the initial moment, at 1 minute, 10 minutes, 20 minutes, 30 minutes, 40 minutes and 50 minutes of the contact of the three phases.
    [0103]
    [0104]
    [0105]
    [0106]
    [0107] From the results obtained, it should be noted that the supports of samples 2 and 3 have a percentage of oxygen at room temperature between 35 and 40% in the period of time between the initial 10 and 30 minutes after the reaction of the three phases .
    [0108]
    [0109] The reproducibility of these trials was verified by repeating the experiments.
    [0110]
    [0111] Finally, the tests for the determination of the destruction capacity of the bad odors of the prepared samples are detailed. Specifically, the washing simulation is carried out by adding a malodorous agent similar to the molecule responsible for the bad odors in the tissues impregnated with sweat. In this case, 2-methyl-2-propanothiol has been used. The main characteristics of this thiol is that it has low molecular weight, has a strong odor and high miscibility in water.
    [0112]
    [0113] The parameters used to verify the destructiveness of bad odors from One of the prepared samples has been the following:
    [0114]
    [0115] - 500 milliliters of distilled water,
    [0116] - 6.25 grams of commercial Marseille soap,
    [0117] - 0.32 grams of sodium carbonate peroxyhydrate,
    [0118] - 0.25 grams of sample 2,
    [0119] - 1 milliliter of 2-methyl-2-propanothiol,
    [0120] - Ambient temperature and continuous stirring.
    [0121]
    [0122] The reaction was analyzed by gas chromatography - mass spectrometry. This analysis technique is based on separation based on the mass / charge ratio of the charged species formed from the ionization of a sample. It is a technique with a high detection sensitivity and well known.
    [0123]
    [0124] The curves obtained by gas chromatography - mass spectrometry (GC-MS) are shown in Figure 2. Specifically, curve A represents the analysis performed at the initial moment of bringing the three phases into contact with the compound 2-methyl-2-propanothiol. Curve B represents the analysis at 15 minutes, curve C the analysis performed at 30 minutes, and curve D represents the result obtained one hour after the three phases have been brought into contact, with the molecule of 2- methyl-2-propanothiol.
    [0125]
    [0126] On the abscissa axis the retention time expressed in seconds is represented and on the ordinate axis the signal obtained by GC-MS expressed in milli volts is represented, the signal being related to the abundance of the compound to be measured in the analyzed sample.
    [0127]
    [0128] In this way, the comparison of curves A, B, C and D of Figure 2 allows us to observe the peak that indicates the presence of 2-methyl-2-propanothiol, which has a retention time in GC-MS of 2.97 minutes, and that has been disappearing as the reaction times between the detergent object of the present invention and the odor generating compound increased.
    [0129]
    [0130] Therefore, it can be concluded that the disappearance of this peak indicates the ability to "Degradation" of the bad odors that sample 2 possesses when combined with the peroxide and soap solution phases of the detergent object of the invention.
