    [0002] Solid shampoo and procedure for its preparation
    [0004] Technical field of the invention
    [0006] The present invention corresponds to the technical field of personal hygiene products, specifically a solid state hair shampoo, as well as a method for obtaining the same.
    [0008] Background of the Invention
    [0010] In the preparation of hair shampoos, a simple process is followed in the usual way with a first phase of agitation of the ingredients, followed by a deposit phase and a final phase of recirculation of the same to obtain the resulting liquid. This type of shampoo thus obtained are the traditional liquid shampoos that have been widely used since they were created.
    [0012] Currently, given the growing awareness of a necessary protection of the environment, there is a tendency to reduce the use of plastics, so that many products have started or even returned to a bulk presentation, so that consumers can purchase the quantities needed through reusable packaging, more respectful with the environment.
    [0014] In this sense, the presentation format of some products is also being modified, so that, instead of being presented in a liquid state, in which they again require containment containers, they are offered in a solid state, thus eliminating that dependence on a container.
    [0016] One of the products that is increasingly being developed in solid form is shampoo. Since the first version of solid shampoo appeared, more and more users are opting for this option, since they avoid the use of containers and allow reducing the production of plastics.
    [0018] In the production of shampoos or soaps in general, it is always necessary to use a fatty acid, be it a vegetable oil or animal fat and an alkali, sodium hydroxide, commonly known as soda. A reaction consisting of saponification must be carried out between both, which consists of the reaction of soda with water and fatty acids, generating the association between them, resulting in soap. For this reaction to take place, it is essential to use alkali, soda, and this is a dangerous caustic element that requires handling with safety precautions, as well as important control of both the process and said substances, to that the product finally obtained does not pose risks to the user's skin.
    [0020] In ancient times, the saponification process was carried out cold, however, current industrial processes for making soaps, and specifically in the case at hand, shampoos, carry out hot saponification, since it is a much faster and cheaper process. The drawback is that the product obtained is a very low-quality soap, since it is a product that reduces its cleaning capacity and also has lost vitamins and glycerin, so it is not moisturizing, moisturizing, or nourishing.
    [0022] Therefore, it is necessary to find a way to obtain a solid shampoo, with the advantages that this entails and that at the same time the union of the different substances is achieved without carrying out a saponification, avoiding industrial processes that revert to disadvantages of the final product.
    [0024] In addition, it would be advisable at the same time to get a solid shampoo that avoids the use of sulfates, because, although these substances have the property of trapping dirt, when rinsing them they drag the oils from the hair fiber along with it, resulting in a hair more dry and dehydrated.
    [0026] Description of the invention
    [0028] The solid shampoo presented here comprises a cleansing and foaming agent made up of at least one first surfactant, in a percentage between 85 and 97%, at least one solvent made up of water, in a percentage between 1.5 and 3.5% and an emulsifying agent, in a percentage comprised between 0'0005 and 0.01%, where these values refer to percentages on the weight of the final product.
    [0029] In this specification, a process for preparing a solid shampoo as previously defined, comprising the following phases, is also proposed.
    [0031] A first phase consisting of a first grinding of a first solid surfactant or surfactant, presented in the form of flakes, until a homogeneous powder with a particle size less than or equal to 0.1mm is obtained.
    [0033] This first grinding is carried out simultaneously with stirring by means of rotation at 10 rpm and for a time of between 8 and 12 minutes.
    [0035] A second phase of addition of at least one solvent consisting of water.
    [0037] Subsequently, a third phase is formed by a second grinding of the mixture at a speed lower than that of the first grinding, simultaneously with stirring by means of rotation at a speed of 10 rpm.
    [0039] This is followed by a fourth phase of adding an emulsifying agent to the mixture once the second grinding has started.
    [0041] This second grinding and stirring of the mixture together with the emulsifying agent added to it is carried out for a time between 4 and 7 minutes.
    [0043] Once this period of time has elapsed, a fifth resting phase of the dough obtained takes place in a closed container for at least 24 hours.
    [0045] Next, a sixth phase of introduction of a quantity of dough into a given mold is carried out.
    [0047] Next, a seventh phase of closing the mold and applying on it an increasing pressure from 1 ton to 10 tonnes.
    [0049] And, finally an eighth phase of demoulding of the obtained shampoo bar.
    [0051] With the solid shampoo and the manufacturing process of the same as proposed here, a significant improvement of the state of the art is obtained.
    [0052] This is so because a solid shampoo is achieved that, in addition to presenting the advantages of being more respectful with the environment because it does not require packaging, it is a shampoo in which a saponification reaction does not intervene, so it is not soap itself , but it does have the right characteristics for hair cleansing treatment.
    [0054] By not carrying out a saponification of the intervening substances, the handling of dangerous substances is eliminated, as well as the disadvantages that this process presents when it is carried out in an industrial way, in hot, and instead a shampoo elaboration process is carried out different from the rest of shampoos.
    [0056] This elaboration procedure proposed here is very simple and easy to elaborate, and achieves compatibility in the union of the different substances used, not requiring the application of high temperatures but a simple crushing and mixing of the same, on which the pressure required to form the shape of a desired mold.
    [0058] On the other hand, by eliminating any use of sulfates, a highly foaming shampoo is obtained that at the same time is less aggressive when in contact with the eyes and less irritating to the skin, so it is appropriate for anyone, even those with leather. very sensitive scalp.
    [0060] Detailed description of a preferred embodiment of the invention
    [0062] In a preferred embodiment of the invention, the solid shampoo proposed here comprises a cleansing and foaming agent made up of at least one first surfactant, in a percentage between 85 and 97%, at least one solvent made up of water. in a percentage between 1.5 and 3.5% and, an emulsifying agent, in a percentage between 0'0005 and 0.01%, where these values refer to percentages on the weight of the final product .

    [0081] This specification also presents a process for preparing a solid shampoo as previously defined, which comprises a series of phases that are detailed below.
    [0083] A first phase consists of a first grinding of a first solid surfactant or first surfactant, presented in the form of flakes, until a homogeneous powder with a particle size less than or equal to 0.1mm is obtained. In this preferred embodiment of the invention, this first surfactant used is sodium lauroyl methyl isethionate.
    [0085] This first grinding is carried out simultaneously with stirring by means of rotation at a speed of 10 rpm and for a time of between 8 and 12 minutes. In this preferred embodiment, this first phase is carried out for a period of 10 minutes.
    [0087] Once this grinding and stirring of the first surfactant has been completed, in this preferred embodiment of the invention, the process comprises a first step of adding a second surfactant, a first conditioner and a first antistatic substance. Then a second stage of mixing takes place by means of a paddle, of these elements with the result that has been obtained by the first crushing, until obtaining a premix.
