Les recherches menées depuis plusieurs années sur les matériaux et/ou les procédés de fabrication de protections hygiéniques ont abouti à des produits de plus en plus perfectionnés qui offrent à la fois de bonnes conditions de confort et d'hygiène.Research carried out for several years on materials and / or processes for manufacturing hygienic protections has resulted in increasingly sophisticated products which offer both good conditions of comfort and hygiene.

Il existe cependant toujours un besoin dans le développement de produits capables d'offrir un niveau de protection et d'hygiène encore plus important. L'invention a pour but de répondre à ce besoin en proposant une nouvelle protection hygiénique améliorée.However, there is still a need in the development of products capable of offering an even higher level of protection and hygiene. The invention aims to meet this need by providing a new improved hygienic protection.

La protection hygiénique selon l'invention, utilisable pour l'hygiène infantile, adulte et/ou l'hygiène médicale, comprenant au moins une feuille extérieure imperméable, un voile perméable et une couche absorbante disposée entre ladite feuille extérieure et ledit voile perméable, se caractérise en ce qu'elle comprend un ou plusieurs antiseptiques.The hygienic protection according to the invention, which can be used for infant, adult and / or medical hygiene, comprising at least one impermeable outer sheet, a permeable veil and an absorbent layer disposed between said outer sheet and said permeable veil, is characterized in that it comprises one or more antiseptics.

Avantageusement, le ou les antiseptiques utilisés dans le cadre de la présente invention sont choisis parmi les antiseptiques naturels.Advantageously, the antiseptic (s) used in the context of the present invention are chosen from natural antiseptics.

Selon une forme de réalisation de la présente invention, l'antiseptique est d'origine naturelle et est choisi parmi les huiles essentielles, notamment celles d'origine végétale.According to one embodiment of the present invention, the antiseptic is of natural origin and is chosen from essential oils, in particular those of vegetable origin.

On citera à titre d'exemples non limitatifs d'antiseptiques natures utilisables dans le cadre de la présente invention les huiles essentielles de géranium, de lavande ou de citronnelle. Selon une autre forme de réalisation de la présente invention, l'antiseptique naturel consiste essentiellement en huile essentielle de Melaleuca alternifolia.Mention will be made, by way of nonlimiting examples of natural antiseptics which can be used in the context of the present invention, essential oils of geranium, lavender or lemongrass. According to another embodiment of the present invention, the natural antiseptic consists essentially of essential oil of Melaleuca alternifolia.

L'huile essentielle de Melaleuca alternifolia est obtenue notamment par distillation à la vapeur d'eau de feuilles fraiches et de rameaux du Melaleuca alternifolia, tel que décrit notamment dans la publication Phytotherapy, Septembre 1985, n° 15, pp. 5-8.The essential oil of Melaleuca alternifolia is obtained in particular by steam distillation of fresh leaves and twigs of Melaleuca alternifolia, as described in particular in the publication Phytotherapy, September 1985, n ° 15, pp. 5-8.

Selon une autre forme de réalisation de ia présente invention, l'antiseptique naturel consiste en un mélange comprenant essentiellement, en pourcentage par rapport au poids :According to another embodiment of the present invention, the natural antiseptic consists of a mixture essentially comprising, in percentage relative to the weight:

- environ 35 % de terpinène-1-ol-4 ; - environ 20 % de gamma terpinène ;- about 35% of terpinene-1-ol-4; - about 20% of gamma terpinene;

- environ 10 % d'alpha terpinène ;- about 10% of alpha terpinene;

- environ 5 % de cinéole ; et- about 5% of cineole; and

- environ 20 % de p-cymène.- about 20% p-cymene.

De préférence, la protection hygiénique selon l'invention comprend d'environ 0,2 mg à environ 20 g d'antiseptique.Preferably, the hygienic protection according to the invention comprises from approximately 0.2 mg to approximately 20 g of antiseptic.

Selon l'invention, l'antiseptique naturel peut être déposé sur la protection hygiénique sous forme pure.According to the invention, the natural antiseptic can be deposited on the hygienic protection in pure form.

Selon une forme de réalisation de la présente invention, l'antiseptique peut être déposé sur la protection hygiénique sous une forme de gel ou de poudre sèche ou encore sous une forme diluée par exemple en solution aqueuse ou en solution anhydre. En variante, il peut être dissout grâce à un agent solubilisant ou un solvant, notamment alcoolique, par exemple l'alcool éthylique.According to one embodiment of the present invention, the antiseptic can be deposited on the hygienic protection in the form of a gel or dry powder or else in a diluted form, for example in aqueous solution or in anhydrous solution. As a variant, it can be dissolved using a solubilizing agent or a solvent, in particular an alcoholic solvent, for example ethyl alcohol.

Le choix de l'agent solubilisant n'est pas critique en lui-même et il peut s'agir, notamment lorsque l'antiseptique est une huile essentielle, de tout agent tensioactif utilisé pour des produits liposolubles.The choice of the solubilizing agent is not critical in itself and it may be, in particular when the antiseptic is an essential oil, any surfactant used for liposoluble products.

De préférence, le poids total de la solution antiseptique contenue dans la protection hygiénique selon l'invention ne dépassera pas environ 20 g. Selon une forme de réalisation de la présente invention, la solution antiseptique comprend d'environ 1% en poids à environ 10 % en poids, par rapport au poids total de la solution, d'huile essentielle de Melaleuca alternifolia dans un agent solubilisant consistant en un mélange d'oxyéthylène glycérile de coprah, d'oxyéthylène de cétylstéaryle, d'oxyéthylène d'huile de ricin hydrogénée et de l'eau distillée. Selon une autre forme de réalisation de la présente invention, la solution antiseptique comprend d'environ 2 % en poids à environ 30 % en poids, par rapport au poids total de la solution, d'huile essentielle de géranium dans un agent solubilisant consistant en un mélange d'oxyéthylène glycérile de coprah, d'oxyéthylène de cétylstéaryl, d'oxyéthylène d'huile de ricin hydrogénée et de l'eau distillée.Preferably, the total weight of the antiseptic solution contained in the hygienic protection according to the invention will not exceed approximately 20 g. According to an embodiment of the present invention, the antiseptic solution comprises from approximately 1% by weight to approximately 10% by weight, relative to the total weight of the solution, essential oil of Melaleuca alternifolia in a solubilizing agent consisting of a mixture of coconut glyceryl oxyethylene, cetylstearyl oxyethylene, hydrogenated castor oil oxyethylene and distilled water. According to another embodiment of the present invention, the antiseptic solution comprises from approximately 2% by weight to approximately 30% by weight, relative to the total weight of the solution, of geranium essential oil in a solubilizing agent consisting of a mixture of coconut glycerile oxyethylene, cetylstearyl oxyethylene, hydrogenated castor oil oxyethylene and distilled water.

Selon une variante de réalisation de la présente invention, en particulier lorsque l'antiseptique utilisé possède une odeur pouvant être désagréable, la protection hygiénique selon l'invention comprend de plus un ou plusieurs parfums, tels que ceux utilisés de façon conventionnelle dans les produits cosmétiques. On citera à titre d'exemples non limitatifs de parfums utilisables dans le cadre de la présente invention les essences de citron, de muguet, de tangerine distillée, de jasmin ou de lavande.According to an alternative embodiment of the present invention, in particular when the antiseptic used has an odor which can be unpleasant, the hygienic protection according to the invention further comprises one or more perfumes, such as those conventionally used in cosmetic products . Mention will be made, by way of nonlimiting examples of perfumes which can be used in the context of the present invention, of the essences of lemon, lily of the valley, distilled tangerine, jasmine or lavender.

Par exemple, le ou les parfums peuvent être présents dans la protection hygiénique de l'invention, à une concentration variant entre environ 1 % et environ 5 % en poids par rapport au poids de l'antiseptique.For example, the perfume (s) may be present in the hygienic protection of the invention, at a concentration varying between approximately 1% and approximately 5% by weight relative to the weight of the antiseptic.

Selon une autre forme de réalisation de la présente invention, la protection hygiénique de l'invention comprend de plus un agent conservateur, protecteur à l'égard notamment des bactéries, des levures et/ou des champignons. Précisément, l'agent conservateur peut être utilisé à une concentration variant entre environ 0,1 % en poids et environ 1 % en poids par rapport au poids de l'antiseptique.According to another embodiment of the present invention, the hygienic protection of the invention further comprises a preservative, protective with regard in particular to bacteria, yeasts and / or fungi. Specifically, the preservative can be used at a concentration varying between about 0.1% by weight and about 1% by weight relative to the weight of the antiseptic.

On citera à titre d'exemple non limitatif d'agent conservateur utilisable dans le cadre de la présente invention, le produit disponible auprès de la Société Hassiauer, France, sous la dénomination commerciale « Bactiphen 2506 G ». La solution antiseptique peut être déposée sur la protection hygiénique selon l'invention par tout moyen connu en soi. Par exemple la solution antiseptique est déposée par pulvérisation ou encore par buse léchante ou sans contact pendant le processus de fabrication de la protection hygiénique, de préférence à la fin de celui-ci.Mention will be made, by way of nonlimiting example of a preservative usable in the context of the present invention, of the product available from the company Hassiauer, France, under the trade name "Bactiphen 2506 G". The antiseptic solution can be deposited on the hygienic protection according to the invention by any means known per se. For example, the antiseptic solution is deposited by spraying or else by a licking or contactless nozzle during the manufacturing process of the hygienic protection, preferably at the end of it.

Par exemple, l'antiseptique est déposé avantageusement sur les éléments constitutifs de la protection hygiénique en contact avec la peau ou les muqueuses.For example, the antiseptic is advantageously deposited on the constituent elements of hygienic protection in contact with the skin or the mucous membranes.

Selon une autre forme de réalisation de la présente invention, l'antiseptique est déposé sur les éléments constitutifs de la protection hygiénique possédant une perméabilité suffisante pour permettre un transfert de l'antiseptique vers la peau ou les muqueuses et, ainsi un contact de l'antiseptique avec la peau ou les muqueuses.According to another embodiment of the present invention, the antiseptic is deposited on the constituent elements of the hygienic protection having sufficient permeability to allow a transfer of the antiseptic to the skin or the mucous membranes and, thus a contact of the antiseptic with the skin or mucous membranes.

Ainsi, dans le cas où la protection hygiénique est une couche- culotte infantile, l'antiseptique peut être déposé au niveau du voile interne.Thus, in the case where the hygienic protection is an infant diaper, the antiseptic can be deposited at the level of the internal veil.

Selon une autre forme de réalisation de la présente invention, l'antiseptique peut être déposé au niveau du voile intermédiaire.According to another embodiment of the present invention, the antiseptic can be deposited at the level of the intermediate veil.

Selon une autre forme de réalisation de la présente invention, l'antiseptique est déposé sur la protection hygiénique dans un état encapsulé dans un véhicule, par exemple dans un polymère lipophile lorsque l'on utilise un antiseptique huileux pur ou dilué dans une huile.According to another embodiment of the present invention, the antiseptic is deposited on the hygienic protection in a state encapsulated in a vehicle, for example in a lipophilic polymer when using an oily antiseptic pure or diluted in an oil.

De cette façon, les éventuels inconvénients posés par l'odeur que peuvent dégager certains antiseptiques sont éliminés.In this way, the possible drawbacks posed by the odor which certain antiseptics can give off are eliminated.

La technique d'encapsulation ou de micro-encapsulation utilisée dans le cadre de la présente invention est classique en elle-même et n'a pas besoin d'être décrite plus en détail ici.The encapsulation or microencapsulation technique used in the context of the present invention is classic in itself and does not need to be described in more detail here.

En variante, le ou les antiseptiques peuvent être déposés à l'aide de vecteurs habituellement utilisés dans l'industrie chimique ou cosmétologique, tels que liposomes ou phospholipides, pour permettre une action différée de l'antiseptique et/ou assurer un rôle de protection du principe actif vis-à-vis de l'extérieur. Des avantages et caractéristiques supplémentaires de la présente invention apparaîtront encore à la lumière de la description plus détaillée qui suit d'un exemple de réalisation de ia présente invention, donné uniquement à titre illustratif et non limitatif. EXEMPLE :As a variant, the antiseptic (s) can be deposited using vectors usually used in the chemical or cosmetological industry, such as liposomes or phospholipids, to allow a delayed action of the antiseptic and / or to provide a protective role for the active ingredient vis-à-vis the outside. Additional advantages and characteristics of the present invention will become apparent in the light of the more detailed description which follows of an exemplary embodiment of the present invention, given solely by way of illustration and without limitation. EXAMPLE:

Sur une couche-culotte pour enfant comportant un voile interne de polypropylène hydrophile, une feuille extérieure de polyéthylène et une couche absorbante de ouate de cellulose entre te voile interne et la feuille extérieure, est déposée par pulvérisation une solution contenant 0,02 g d'huile essentielle de Melaleuca alternifolia en solution dans 0,04 g de l'agent solubilisant « Solubilisant 3 RS », disponible commercialement auprès de la Société Hassiauer, France et 0,5 g d'eau distillée.A solution containing 0.02 g of a spray solution is deposited on a children's diaper comprising an inner veil of hydrophilic polypropylene, an outer sheet of polyethylene and an absorbent layer of cellulose wadding between the inner veil and the outer sheet. essential oil of Melaleuca alternifolia in solution in 0.04 g of the solubilizing agent "Solubilizer 3 RS", commercially available from the Company Hassiauer, France and 0.5 g of distilled water.

Après conservation dans son emballage commercial pendant au moins un an à température ambiante, la couche-culotte montre une action positive contre les agents pathogènes Staphylococcus Curreus, Escherichia Coli, Pseudomonas Aeruginosa, Cnadida Albicans et Aspergillus Niger.After storage in its commercial packaging for at least one year at room temperature, the diaper shows a positive action against the pathogenic agents Staphylococcus Curreus, Escherichia Coli, Pseudomonas Aeruginosa, Cnadida Albicans and Aspergillus Niger.

Il va de soi que la présente invention n'entend pas se limiter à la forme de réalisation qui vient d'être décrite mais en embrasse au contraire toutes les variantes. L'homme du métier aura tout loisir de modifier certains des éléments de la présente invention sans pour autant sortir du cadre de ses caractéristiques essentielles, telles que décrites dans les revendications qui suivent. It goes without saying that the present invention does not intend to be limited to the embodiment which has just been described but on the contrary embraces all variants. Those skilled in the art will be free to modify some of the elements of the present invention without going beyond the scope of its essential characteristics, as described in the claims which follow.
