Description

DESCRIPTION

Water-soluble and hydrodegradable polyvinyl alcohol resin non-woven fabric wet wipe, sprayed with saponified vegetable oil oleaginous sanitizers

Technical sector

The present invention refers to a disposable wet wipe for hygienic, cosmetic, pharmaceutical, medical or sanitary use, made of non-woven fabric of polyvinyl alcohol resin, 100% water soluble instantly in contact with cold or hot water, 100% hydrodegradable and 100% biodegradable, on which a liquid oleaginous sanitizer made 100% with vegetable oils by the cold saponification process is sprayed, 100% biodegradable, 100% natural and 100% vegan, forming the conjunction of both elements a disposable product, totally water soluble, totally biodegradable and respectful with the environment, animal and marine.

Therefore, the present invention falls within the technical sector of products for personal hygiene, cosmetic products, pharmaceuticals, medical or health; specifically, cosmetic products and non-medicinal toilet preparations framed in CLASS NICE 03 and pharmaceutical products and preparations for medical use as well as hygienic and sanitary products for medical use, framed in CLASS NICE 05 .

Background of the invention

Although no invention identical to that described has been found, we present below the documents found that reflect the state of the art related thereto.

Currently, a large number of wet fabrics are used for hygiene and skin care, such as that contained in document ES-2543865-A1 and which refers to a non-woven fabric wipe, which comprises fibers linked together, characterized because said fibers have a length between 4 and 18 mm, all the fibers being of the same length or of different length and in which said fibers are curly and natural fibers such as cellulose, viscose or rayon. From said fabric a personal hygiene wipe is formed, which is formed from the non-woven fabric in accordance with the above.

On the other hand, we also find another wet wipe made of non-woven fabric, such as the one contained in document ES-2694303-A1 and in which it refers to a wet wipe to treat bedsores, ulcerations and other dermatological conditions, made up of a biodegradable matrix. disposable, impregnated with an aqueous, saline, biologically compatible solution, characterized by comprising said solution a combination of compatible inorganic salts and an emollient, said combination of inorganic salts being able to include sodium chloride or potassium chloride or other appropriate inorganic salt in a concentration from 0.1 to 9 grams per 100 grams of aqueous solution and said emollient may include glycerin as an emulsifying agent. Said wet wipe for treating bedsores, ulcerations and other dermatological conditions, is characterized in that said biodegradable and disposable matrix is constituted by an absorbent cellulosic matrix of mechanically joined fibers that have an absorbent capacity of approximately 1 to 5 grams of solution per 1 gram of matrix and a biologically soluble alcohol-free aqueous solution impregnated in the matrix, the amount of solution impregnated in said matrix being less than approximately 80 percent of its absorbent capacity, so that the matrix has unused absorbent capacity , said quantity being sufficient to apply the solution to a surface, and said solution comprising the inorganic salt referred to above in the given concentration.

That is why the current fabrics used in the elaboration of these wet wipes for corporal hygiene, intimate hygiene and for other cosmetic uses, are generally textile fabrics of threads and / or woven fibers, of synthetic composition originating from petroleum, natural, or natural celluloses; Many of these, after use, are flushed down the toilet and, as they are not fragmentable or insufficiently fragmentable, they cause major blockages in sewage networks and in city collectors; and those that do not get clogged, continue their way to the sewage pumping stations, clogging the pumps or ending their trip in the treatment plants, which therefore entails a high cost in their maintenance and cleaning.

This occurs because these wipes are not 100% soluble in water or they fragment into large pieces due to their textile or woven fiber composition, which causes them to float and not fragment or fragment insufficiently, being able to reach the river bed. rivers with the consequent environmental damage that this entails.

Natural fiber wipes are at most 33% efficient in their decomposition, being celluloses, to date, the most effective hygiene items (such as toilet paper), which will still need several hours to supply such a decay effect, and they generally remain a problem for jams.

On the other hand, and as an integral part of the aforementioned problem, the impregnated wipes that are marketed and used for body hygiene do not provide a definitive solution for effective hygiene and treatment of dermatological conditions of inflammatory, viral, fungal and bacterial.

In conclusion: The wipes that currently exist on the market, both the cleansers or those used to treat certain dermatological conditions, are not effective in their decomposition 100% by the toilet, nor do they use 100% natural impregnations that respect the environment. , animal and marine. Consequently, they imply a high economic and environmental cost that has yet to be resolved.

To solve this problem, it would be beneficial to obtain a novel product (sanitizing fabric) 100% biodegradable, 100% natural, 100% ecological and 100% soluble in water immediately, that does not float, that does not contain microplastics or any other. minimally polluting material for the environment, animal or marine, and that also has exceptional properties both in the hygienic and regenerative field of skin conditions.

Explanation of the invention

The invention consists of a hydrodegradable flexible sheet, with the international application number PCT / CL20 17/000021 and with the international publication number WO 2018/018172 A1, on which, adapting its manufacturing process, wipes of different thicknesses are obtained ( between 10 and 60 microns), weights (between 15 gr / m2 and 150 gr / m2), measurements (length between 5 cm and 30 cm; width between 5 cm and 30 cm; diameter between 4 and 12 cm), shapes (square , rectangular and round) and formats (packs; single-dose), to which a liquid oleaginous sanitizer of 100% vegetable origin is sprayed, using a system of the known type, obtained by cold saponification procedures using already known means.

As we have indicated previously, the thickness of the wipe must be greater than 10 microns since its manufacture becomes impractical with lower thicknesses, and the thickness must not exceed 60 microns because its use would not be practical since it becomes little ductile. The weight of the wipe must be between the aforementioned ranges, since less than 15 gr / m2 it fragments easily and greater than 150 gr / m2 is too hard to be treated. The measures and shapes indicated are the most suitable for practical use for the different dermal utilities to be sanitized, and can be used easily, quickly and comfortably. On the other hand, the packs to be formed will be made up of 5 wipes or 10 wipes or 15 wipes or 20 wipes or 40 wipes or 50 wipes or 100 wipes or 200 wipes per pack, as well as single dose format; all of them will be housed in a sterilized container of a sanitary or cosmetic type.

The wipe that we obtain from the aforementioned sheet has the characteristic of being odorless and non-toxic, very smooth, with great resistance to traction and great flexibility.

The referred polyvinyl alcohol non-woven fabric impregnated with the oleaginous sanitizer, in contact with water, both cold and hot, is completely water-soluble: in cold water (temperature between 2 ° C and 22 °) between 1 and 10 minutes, in warm water (temperature between 22 ° and 30 °) between 20 seconds and 60 seconds and in hot water (temperature between 30 and 100 °) between 3 and 60 seconds, not causing any damage to the environment, animal or marine.

The invention is constituted as a new concept of disposable wet wipe for hygienic, cosmetic, pharmaceutical, medical or sanitary use, made of non-woven fabric of polyvinyl alcohol resin, 100% water soluble instantly in contact with cold or hot water, antibacterial , ecofriendly, antipull (not abrasive or exfoliative), resistant to traction, meltable with other products, 100% hydrodegradable (completely decomposing on contact with water) and 100% biodegradable (integrating into the environment when dissolving in water ), on which a liquid oleaginous sanitizer made 100% with vegetable oils by the cold saponification process is sprayed, 100% biodegradable, 100% natural and 100% vegan, the conjunction of both elements forming a disposable, totally water-soluble product. totally biodegradable and respectful with the environment, animal and marine, leaving no polluting traces in the solution.

The oleaginous sanitizer to be sprayed on the wipe is made by a cold saponification process using well-known procedures. With this process we will make a soap paste with vegetable oils and potassium hydroxide, potassium salt and other alkalis, according to the formula and dermal properties to be incorporated into the sanitizer, on a stainless steel tank with industrial agitation with known means, at a temperature between 25 ° C and 40 ° C which is allowed to stand for a period of 2 hours until the total disappearance of the alkalis.

Once the paste has been completely saponified, it is diluted in a mixture of natural solvents using known methods until it is completely homogenized. With this homogenization process by known methods, we control the exact percentage of water that the mixture of sanitizer and solvent must carry to be sprayed on the wipe so that it does not fragment or dissolve prematurely, thus maintaining all its physical properties and dermatological until use, since it is 100% water soluble.

The oleaginous sanitizer to be sprayed on the wipe object of this invention is made up of vegetable oils such as organic olive oil, extra virgin olive, coconut, ricin, almond, wheat germ, grape seed, hypericum, argan, shea, etc. avocado, calendula, hazelnut, jojoba, rosehip, soybean, apricot, chamomile, evening primrose, sunflower and squalene, as well as with different essential oils, oleates and hydrolates which are saponified when mixed with sodium hydroxide or potassium hydroxide.

The combination of the different oils that make up the formula corresponding to the dermal pathology to be sanitized, intrinsically attributes to the product exceptional qualities and properties as a sanitizer for dermal conditions such as: nourishing, moisturizing, antiseptic, antibacterial, emollient, moisturizing, fungal , anti-inflammatory, astringent, skin conditioner, antioxidant, toning, anti-fat, healing and regenerating the skin, all depending on the applied formulation.

A characteristic of the invention is that its mixture of fatty acids contained in the vegetable oils indicated above and that make up the composition of the sanitizer, is comprised between 70% to 100% of the total mixture, these being absorbable by the skin which, depending on of the pathology to be sanitized, will be made of unsaturated fatty acids of one type or another or will have a more or less percentage of them in the formulation, as indicated above.

The resulting invented wipe, due to its composition and the oleaginous sanitizer sprayed on it, is a product with low bacteriological contamination, so it could have a shelf life of 36 months or an ODP of 6 months.

The wipe object of this invention is properly sterilized and housed in a sanitary and hermetic container, thus preserving its sterility until the moment of use.

Finally, it is important to note that with this invention we solve three important problems:

a) the problem of blockages in collectors and contamination in the environment, b) the daily hygiene of sensitive, delicate or weak skin in order to mitigate, reduce or heal skin diseases of the fungal, inflammatory, viral, parasitic or bacterial.

c) It is an easy product to manufacture and reproduce by the means currently known in the industry and with a low production cost.

A main characteristic of the oleaginous sanitizer impregnated wipe is that it has filmogenic properties (that a film remains on the skin after its application on it) and is applied by rubbing gently on the skin, leaving the sanitizer adhered to it in order to provide it. its intrinsic properties, not producing foam during its application.

Another main characteristic of the invention is that, when the product is applied to the skin, it will absorb almost all of the oils that compose it, performing the dermal or hygienic function for which it has been formulated. Once applied, and depending on the sanitizer impregnated on the skin, the product will need to be rinsed or not, depending on its final functionality.

Its applications are very diverse and its field of action is expanding every day due to the benefits that we have already mentioned.

Next, the basic uses for the application of the wipe object of the invention are described, which will be impregnated with the corresponding oleaginous sanitizer, having one task:

a) As a cleanser for facial use

b) As a cleanser for fragile, sensitive or delicate skin

c) As a body cleanser

d) for feminine hygiene

e) for hemorrhoid hygiene

f) for anal and perianal hygiene

g) for hygienic and cosmetic use

h) as a make-up remover

i) for baby hygiene

j) as an antiseptic for topical use

k) hygiene of skin diseases of fungal origin

l) hygiene of skin diseases of inflammatory origin

m) hygiene of skin diseases of viral origin

n) hygiene of skin diseases of parasitic origin

o) hygiene of skin diseases of bacterial origin

p) for pharmaceutical use

q) for medical use

r) for sanitary use

Among many others, the benefits that are provided with this novel invention, with water-soluble and biodegradable characteristics, is that the health of sensitive, delicate, fragile skin or skin with dermatological problems is considerably improved in an effective, fast, simple and natural way. facilitating and also giving solution to a problem of interpretation of how to dispose of this type of products; Any form of recycling that could be used for this novel invention (toilet, sink, organic waste, or any other form of recycling) would be suitable, viable, efficient and equally responsible with the environment.

It should be noted as a property of the invention that the wipe is suitable to be used anywhere, by anyone without age restriction, since, if the wipe were thrown onto the public highway, it would rapidly degrade due to the effects of humidity. environmental or rain.

Said wipe can be manufactured industrially in any of the production processes or factories of known type that currently exist in the market, since only the raw materials used are modified, which in this case are the non-woven polyvinyl alcohol fabric and the natural oleaginous sanitizer, making this singular and inseparable union an innovative invention with structural and constitutive characteristics unknown until now, reasons that, together with its practical usefulness, provide it with a sufficient foundation to obtain the privilege of exclusivity that is requested.
