    DESCRIPTION

    Dermal foam without gas.

    Technical sector 5

    The present invention relates to a gas-free dermal foam in shaving, hair removal, hydration systems, etc. The foam has been conceived and realized to obtain numerous and notable advantages over other existing means of analogous purposes. 10

    The foam is intended to be applied to the skin, facilitating the extension of its components. For this, the foam has 2 distinct components that react with each other forming a single fluid that is capable of becoming foam. fifteen

    Background of the invention

    There may be mentioned systems consisting of shaving gels that subsequently foam, forming an oil-soluble aqueous emulsion in which the foaming agent 20 is a low boiling fluid, is solubilized in the oil and aqueous phases. The product is packaged in an aerosol container. The foam is generated by the volatilization of the fluid by the change in pressure and energy provided by the skin.
     25
    This system has several drawbacks, such as its action on the skin that leaves it rough and dry due to the soapy component, the cooling of the skin closes the pores reducing its effectiveness, not to mention the high price of the containers, which forces Make it profitable in large volumes, and all this coupled with the danger of explosion of a pressure container, on which you can not risk reducing costs. 30

    Likewise, other systems are known to which emollient humectants, silicones, talc, etc. are added. reducing in this way the adverse effects of the foam.

    However, the efficiency of these additives is very limited, especially in sensitive skin. And of course the foam is notoriously expensive. Without providing new functionality.

    Explanation of the invention.
     40
    The gas-free dermal foam of the invention presents a new strategy when it comes to obtaining the foam, instead of using an expandable propellant at standard temperature we will obtain this foaming as a result of a chemical reaction.

    The foam is designed to achieve foam of any substance capable of supporting it by introducing a gaseous promoter such as hydrogen peroxide and a destabilizer thereof such as catalase. In this way the gaseous promoter will be distributed homogeneously by the matrix capable of constituting a foam and when it is mixed with the destabilizer the bubbles constituting the foam will be produced.
     fifty
    Given the zero pressure that these two elements will exert separately they can be introduced in any container as long as they are kept separately.

    In addition, it is envisaged that the two elements can be in a single container that has two separate compartments, and there may be options to extract 5 fixed amounts of both, or that they are mixed inside the container obtaining only foam therefrom. It is also provided that the foam is packaged in single-dose containers whose opening entails mixing and consequently obtaining a certain amount of foam.
     10
    There is also the possibility that the separation between the gaseous promoter and the destabilizer can be detached as a spatula during opening, facilitating the mixing by turning the spatula and being able to take the spatula out of the container and use it to spread the foam.
     fifteen
    It also contemplates the possibility of implementing a slit through which the foam can escape, but that by limiting the flow rate, it exits with a certain pressure and speed, in addition to allowing a better distribution of the foam on the skin when leaving it is in laminar form.

    Brief description of the drawings

    In order to complete the description that will then be made, and in order to help a better understanding of the features of the invention, the present descriptive specification of a set of drawings is attached, based on whose figures 25 will be more easily understood the innovations and advantages of the device object of the invention.

    In said drawings, Figure 1 represents the complete diagram of the package (3), which contains the two elements, the gaseous promoter (1) and the destabilizer (2) separated 30 by the septum (5), which in turn is constituted partially by the spatula (4) which joins through the slit (7), to the cap (6) that closes the container. So that when unscrewing the cap, the spatula comes out joining the two sides of the septum and mixing the gaseous promoter and the destabilizer.
     35
    Figure 2 represents the basic diagram of the container (3), in which we observe the detail of the slit (7) where the foam motive of the invention would come out after removing the spatula (4) attached to the cap (6) Closing the container

    Figure 3 represents three schematic cuts where we can see how the movement 40 of a spatula (4) when no longer part of the septum (5), communicates the gaseous promoter (1) with the destabilizer (2) and when turning by unscrewing of the cap (6) are mixed creating the foam.

    Preferred Embodiment of the Invention

    At present there are very different substances with which to make the different components of the foam, and multiple techniques that we could use in the packaging. However, for simple economy we will choose generalized materials and techniques that favor the skin. Thus, for the gaseous promoter we will choose 50 hydrogen peroxide, and as its catalase destabilizer. The container will be made to
    Polyethylene Terephthalate (PET) base injected in machined aluminum mold, as well as for the spatula, the septum, and the cap that will also be injected PET. Being the septum thinner than the spatula, and this one, of the dimensions of the slit, which will be implemented in the mold. The union of all the parts will be carried out by thermal fusion. The cap will be the last one to be placed, after filling the container with the gaseous promoter and the destabilizer.

    Consequently, to obtain a single-dose foam canister for a shave, without gas under pressure, we will start from 10 ml of an emulsion of Water, Palmitic acid, Glycerin, sodium stannate, Stearic acid, Myristic acid, Myristic acetyl and Ethylenediaminetetraacetic acid 10 . To which we will add 6% hydrogen peroxide, as a gaseous promoter and deposit it inside the container on one side of the septum while on the other side we will deposit 10 ml of active tasting lasas suspension, at a concentration 10,000 times lower than that of hydrogen peroxide, which will constitute the destabilizer, thus obtaining a decomposition in 5 seconds. And we will place the cap sealing it by fusion and joining it to the spatula.

    In this way, unscrewing the cap will rotate the spatula, removing the gaseous promoter, with the destabilizer and the rest of the emulsion. Once the cap is unscrewed, the spatula is removed through the slit of the container by stretching from the cap. After this, the creation of gas bubbles in the emulsified matrix will create a film around the gas, increasing its volume from 20 ml to 250 ml which does not fit in the container leaving during the following seconds through the slit and being able to apply on the skin, and spread it with the spatula.
     25
    The materials used in the manufacture of the components of the dermal foam, and the packaging, as well as the shapes and dimensions thereof, and all the accessory details that may occur, as long as they do not affect their condition, will be independent of the object of the invention. essentiality.
