    The subject of the present invention is the process for manufacturing a beauty mask with a biocellulosic support in which a bio-cellulose film, produced by a bacterial fermentation of coconut milk, preferably by Acetobacter Xylinum, is cut according to defined forms then impregnated with a cosmetic serum. The viscosity of this serum is adapted so as to simultaneously allow its flat deposition without sag on a heat-sealable flexible film and a homogeneous diffusion within the folded bio-cellulose sheet when it is placed on the serum deposit, allowing control of the final content of the mask's assets. The bio-cellulose sheet is previously covered on both sides with porous polymer films, most often a nonwoven and a honeycomb polyamide, after sterilization by a heat treatment followed by ionization. The whole is packaged in a peelable bag, welded by a thermoformer.

    [0001] 1 Process for producing a cosmetic beauty mask with a biocellulosic support and associated mask Technical field: Cosmetic products. Cosmetics derived from biotechnology. Masks of beauty. The present invention relates to the method of manufacturing a beauty mask for cosmetic use using a bio-cellulosic support. Bio-cellulose, synthesized by bacteria from plant substrate, is known for its regenerative properties and its contribution to the penetration of active agents deep into the skin (Wojciech K. Czaja et al., "The future prospects of microbial cellulose in biomedical applications ", Biomacromolecules, Vol 8 No. 1, January 2007). The state of the art shows that masks composed in whole or part of bio-cellulose are used as cosmetic beauty masks. Thus, the patent EP2011470A1 (L'OREAL) 07.01.09 paragraph 69 and 71, has set forth a method in which the active ingredients are provided in the form of a powder that is partly water-soluble and applied by simple contact with the wet bio-cellulose. However, such a method does not allow a homogeneous distribution of the assets, causing the formation of packets in some places of the support while others will be scarcely sprinkled. Moreover, no particular attention seems to have been paid to the amount of powder dissolved on its surface, which variable affects the final amount of active mask.
    [0002] In addition, the abbreviated US20130244977A1 (AMOREPACIFIC CORP.) Patent 19.09.13, discloses a method of manufacturing by dipping a pure or improved biocellulose sheet into an oily solution containing the active ingredients. Although this technique allows a relatively uniform distribution of the assets, the final amount of these in the mask is difficult to quantify given the metrological bias that induces a bath impregnation. Thus, to the knowledge of the present applicant, it has not been exposed any method of producing a beauty mask using a biocellulosic support that allows a control of the amount of assets satisfactory under the regulations concerning cosmetic products.
    [0003] Furthermore, it is known that the packaging can be made flat by thermoforming a complex on a plastic support to form a tray. The shape of such a package, however, does not guarantee a sufficient maintenance of beauty mask type products, they can move in the tray and lose some of the serum they are impregnated. Methods for sealing peelable bags are also used (Dodrill Dhuanne, "Advances in peelable sealant technology", Rollprint Packaging Products Inc., 2005), however these packaging methods are not a priori not designed to obtain a bio-cellulosic mask regularly impregnated with serum.
    [0004] On the other hand, the bio-cellulose sheet, because of its high water content (up to 95%), is very exposed to the risk of microbiological contamination, hence the need to add preservatives. Different sterilization processes can supplement or supplement these preservatives, heat treatments and ionization being the most commonly used. The latter method, mainly used in the medical field, is mentioned as effective from a dose of 15 kGy, the average dose administered varying between 25 and 35 kGy. It is known in the agri-food field that such radiation dose can induce yellowing of the bacterial cellulose, giving it a repulsive appearance and rendering it unsuitable for use. The applicant company has therefore considered a new solution to overcome the previously mentioned constraints. It has in particular sought to design a beauty mask from a bio-cellulose film synthesized by fermentation of a coconut milk, preferably by Acetobacter Xylinum, sterilized by an effective physico-chemical method and covered with polymer films. porous. The support thus obtained is cut and folded into pre-established forms and impregnated with a serum, comprising active ingredients and additives whose final quantities are controlled and meet the regulatory requirements, conferring on the final product the properties of a cosmetic product, so that the distribution of it on the support is regular. Unexpectedly, it has been demonstrated by the applicant that the heat treatment commonly applied to bio-cellulose, namely exposure at least twice at a temperature of 125 ° C. for a minimum of one half hour and maximum of one hour, was not enough to avoid 35 contaminations in the absence of preservatives. The Applicant then thought to add a gamma ionization step at a dose of 5 kGy at heart, lower than those commonly used, to avoid these contaminations and, together, the alteration of the appearance of the sheet. bio-cellulose. Moreover, the applicant has had the idea of a flat packaging method by a thermoforming machine provided with a zone sterilized by a laminar flow, using a double aluminum complex to form a peelable bag and without requiring the use preformed type trays as in the methods described in the aforementioned article. This process also makes it possible, by the preparation of a suitable serum, a good distribution of this serum in the bio-cellulose sheet. A combination of gelling agents, incorporated in powdered or emulsified form, composed of 0.2 to 0.5% of acrylate and 0.7 to 1.5% of polyacrylate was chosen to give the serum a viscosity of between 0.degree. , 1 and 30 Pa.s, controlled by a Brookfield viscometer using spindle # 6 at 20 rpm. This viscosity allows the serum to spread relatively evenly over the sheet surface while avoiding the risk of sagging when deposited on a horizontal film during packaging. The bio-cellulose film is protected on one of its faces by a polypropylene non-woven fabric which may comprise up to 2% of dye and on its other side by a polyamide film, which may be larger than the cut of the model to facilitate the handling of the product. The biocellulosic support obtained is precut according to models either predefined or defined by the Applicant, in particular for neck and bust forms. The porous structures of these films, and in particular the honeycombed polyamide, promote the diffusion of the serum deposited on their surface in the bio-cellulose sheet.
    [0005] A preferred two-to-fourfold folding mode is applied to the support so that its two apparent faces are covered with polyamide. The folds expose a support surface adapted to that of the serum applied to the packaging film, promoting optimal distribution thereof. Moreover, the dose of serum is calibrated to optimize the impregnation of the support 30 and to determine the final amount of active mask, to comply with current regulations. The serum may contain, typically in a proportion of between 10 and 45% of moisturizing agents, preferably in the form of vegetable glycerine up to 30% supplemented with 0 to 15% of polysaccharides. Different actives may be added depending on the expected cosmetic effects such as aloe vera, sodium hyaluronate, marine collagen or any other well-known ingredient of the art in commonly used amounts. . The serum contains, moreover, preservatives sufficiently effective to ensure both the protection of the serum and the bio-cellulosic carrier, while limiting undesirable effects. Any preservative system well known to those skilled in the art can be used, more particularly, a solution retained will be the use of 0.3% to 1% phenoxyethanol coupled with 0.2% pentylene glycol at room temperature. 2% and Ethylhexyl glycerine from 0.05% to 1.5%. The following list, given by way of example, discloses, non-exhaustively, serum formulas that can be applied to the bio-cellulosic carrier. The amounts of components are given in percentage.

FIGS. 2A and 2B illustrate cutouts specific to the invention applied to the bio-cellulosic support. Figure 3A, 3B and 3C show the folding steps of a bust cut. Figure 4 shows the steps of a horizontal bagging process.
    [0006] The mask models are given as examples of embodiments and are available in several sizes adapted to the morphology of the user. In an exemplary embodiment according to Figure 3B and 3C, a bust model is folded by folding its upper ends (2) in three folds (3), (5) and (4).
    [0007] The neck mask (FIG. 2A), a rectangular cutout provided with two slots (1) intended to facilitate anatomical adaptation, is folded into three thicknesses so that one of the two lateral panels is folded over that of the middle before the second lateral pan is folded over all. According to one embodiment shown in FIG. 4, a defined dose of serum 20 is deposited on a multilayer heat-shrinkable flexible horizontal film (6), typically composed of polyethylene terephthalate, aluminum and polyethylene, a packaging article usually used for manufacturing sachets of cosmetics.
    [0008] The biocellulosic support, composed of a bio-cellulosic sheet (7) covered with a polyamide film (8) and a nonwoven film (10) (FIG. 3B), cut (11) and folded (12), is affixed so that only the polyamide coating (8) is in contact with the serum (9).
    [0009] A second calibrated dose of the serum (9) is applied to the support (12) before a second aluminum film (6) covers the assembly. Thermal welding, carried out by a thermoformer specially designed for this purpose, seals the packaging around the bio-cellulosic mask, forming a peelable bag whose opening is facilitated by a corner leaving part of the two films not welded. If the product does not require folding, the serum (9) will be deposited on only one side of the support (11), preferably that covered with polyamide (8). In another embodiment, the polyamide (8) may be replaced by a nonwoven (10), similar to that already covering the first face of the sheet (10) and capable of protruding from the bio-cellulosic carrier (11). or (12). The composition of the serum (9) will then be adapted to also allow a good diffusion in the mass of the support (12). Implementation and use of the final product: To use the product, open the peel-off bag and unfold the mask. Remove the non-woven fabric, grasp the polyamide if necessary, and place the mask on the part of the body concerned, making it properly adhere to the skin and avoiding the presence of air bubbles. Remove the second film and allow the indicated time to settle before removing the mask from a room.
    [0010] The method is not limited to the simple steps mentioned above, and given by way of illustration of the embodiments.
