Patent Application
20050136083
The present invention relates to a cosmetic article with improved penetration of an active ingredient that includes the simultaneous use of an abrasive device.
The specification WO 94/18879 discloses devices for the cosmetic peeling of the skin using a more specifically determined fabric.
The specifications U.S. Pat. No. 4,459,987 and U.S. Pat. No. 4,712,552 disclose flexible cosmetic emery sheets based on certain polymers which carry emery particles on at least one side.
The specification EP 1219254 discloses an apparatus for the removal of skin.
In none of these documents is anything disclosed concerning applications of such devices extending beyond mere peeling of the skin.
It has proven unforeseeable by the person skilled in the art that a cosmetic and/or dermatological product comprising a device for the removal of skin and an active ingredient-containing cosmetic and/or dermatological preparation where, during use of the product, the device is employed and the preparation is dosed at the same time, overcome the shortcomings of the prior art. When using such a product, the mechanical irritation acts as a physiological stimulus of the skin, which is intensified or compensated for through simultaneous use of the active ingredient.
It has also been found that it is preferred if the device is a large-pored face glove. By using this, the skin is firstly cleansed of dirt. The effect described above takes place to a greater degree.
The large-pored face glove used may be a sisal glove, a peeling glove made of luffa sponge or brush devices supplied with bobbles in glove form or other comparable devices.
It is particularly preferred if the preparation is in the form of a W/O cream. In this connection, it is particularly preferred if an active ingredient is present in the preparation which is chosen very particularly preferably from the group of antioxidants. It is very extraordinarily preferred if it is ubiquinone, ubiquinol, creatine and/or creatinine.
For all this it is preferred if the preparation is dosed by the device as it is used. The invention also covers the use of such a device for increasing the penetration of a cosmetic and/or dermatological active ingredient applied over the course of 30 s, particularly preferably for improving the energy metabolism and/or for stimulating collagen neogenesis or further dermal components. Moreover, the invention also covers a non-therapeutic method for the treatment and prophylaxis of degenerative skin symptoms by using one of the products described above.
Preferably, the abrasive device to be used as cosmetic article simultaneously contains, for the purposes of the invention, active ingredients whose use concentration is in the range from 0.0001% to 50% by weight, particularly preferably 0.01% to 10% by weight (in each case based on the total weight of the preparation).
Use of the device used according to the invention simultaneously with a cosmetic or topical dermatological preparation surprisingly enables effective treatment, but also prophylaxis of certain degenerative symptoms of the skin (e.g. skin slackening, wrinkles, lachrymal sacs, age spots, telangiectases, disturbance of the osmolyte balance, of the natural skin pH, and disappearance of the epidermal and dermal cell layers, the constituents of connective tissue, the retinal cones and capillary vessels of the skin) and/or of the skin appendages,
The device according to the invention together with active ingredient, however, are also surprisingly effective
The omission of an individual constituent can affect the unique properties of the overall composition. Accordingly, the stated constituents of the preparations according to the invention are preferably included to carry out the invention.
Degenerative skin symptoms for the purposes of the present specification are wrinkles, slackening, degeneration, age spots, pigment disorders, circulatory disorders, itching, stress sensitivity, dry skin, cellulite, dermotensions, and fatigue states.
Devices for the removal of skin for the purposes of the present specification are sponges, woven or nonwoven textiles supplied with abrasive particles, textiles containing abrasive fibres or particles, such as wash gloves with or without coconut or hemp fibres, sea cucumber skeleton (luffa), and coarsely woven textiles.
Abrasive particles for the purposes of the present specification are, for example, quartz sand, almond bran, polyethylene, aluminium trioxide, ground fruit cores (walnut or apricot shells), salt crystals, jojoba leaves, ground sepia shells, pumice, zeolites, and silicon dioxide.
For the purposes of the present specification, sponges are natural or artificial. Natural sponges are, for example, coral sponges or pumice sponges, artificial sponges are, for example, large-pored viscose sponges, velour sponges, polyester sponges or polyether sponges. They have a mostly irregular cell structure and pores of varying size. They are flexible and elastic.
Textiles for the purposes of the present specification are wipes, nonwovens, felt, knits, wovens, pads, but also cords, strings, ropes and threads.
Abrasive fibres for the purposes of the present specification are natural or synthetic fibres which have abrasive properties as a result of the nature of their surface, such as hardness or structure, or as a result of their dimensions, such as, for example, hemp, sisal, and coconut fibres.
For the purposes of the present specification, “simultaneously” also means with slight time delay. In particular, for example two functions or properties of a described product simultaneous use of means that these both play a part during one application operation of a product. This can be achieved either by both functions or properties playing a part one after the other, possibly by them being physical separable or separate prior to use. In this case, simultaneously covers a period from 0 to 30 seconds. Preferably, functions or properties play a part simultaneously by them being arranged in an integrated manner in an article. In this case too, “simultaneously” covers a time interval from 0 to about 5 seconds if, for example, the sites of the functions or properties are arranged at a distance from one another, for example 20 mm, and are activated during use at a certain rate, for example 50 mm/s along an application path.
Emulsions are generally understood as meaning heterogeneous systems which consist of two liquids which are immiscible or have only limited miscibility with one another and which are usually referred to as phases. In an emulsion, one of the two liquids is dispersed in the form of very fine droplets in the other liquid.
If the two liquids are water and oil and oil droplets are present in finely divided form in water, then this is an oil-in-water emulsion (O/W emulsion, e.g. milk). The basic character of an O/W emulsion is determined by the water. In the case of a water-in-oil emulsion (W/O emulsion, e.g. butter), the principle is reversed, the basic character here being determined by the oil.
Antioxidants are advantageously chosen from the group consisting of amino acids (e.g. glycine, histidine, tyrosine, tryptophan) and derivatives thereof, imidazoles (e.g. urocanic acid) and derivatives thereof, peptides, such as D,L-carnosine, D-carnosine, L-carnosine and derivatives thereof (e.g. anserine), carotenoids, carotenes (e.g. α-carotene, β-carotene, ψ-lycopene) and derivatives thereof, chlorogenic acid and derivatives thereof, lipoic acid and derivatives thereof (e.g. dihydrolipoic acid), aurothioglucose, propylthiouracil and other thiols (e.g. thioredoxin, glutathione, cysteine, cystine, cystamine and the glycosyl, N-acetyl, methyl, ethyl, propyl, amyl, butyl and lauryl, palmitoyl, oleyl, y-linoleyl, cholesteryl and glyceryl esters thereof) and salts thereof, dilauryl thiodipropionate, distearyl thiodipropionate, thiodipropionic acid and derivatives thereof (esters, ethers, peptides, lipids, nucleotides, nucleosides and salts), and sulphoximine compounds (e.g. buthionine sulphoximines, homocysteine sulphoximine, buthionine sulphones, penta-, hexa-, heptathionine sulphoximine) in very low tolerated doses (e.g. pmol to μmol/kg), and also (metal) chelating agents (e.g. α-hydroxy fatty acids, palmitic acid, phytic acid, lactoferrin), α-hydroxy acids (e.g. citric acid, lactic acid, maleic acid), humic acid, bile acid, bile extracts, bilirubin, biliveridin, EDTA, EGTA and derivatives thereof, unsaturated fatty acids and derivatives thereof (e.g. γ-linolenic acid, linoleic acid, oleic acid), isoflavonoids, licochalcones, licochalcones A (in particular from Radix Glycyrrhizae inflatae), folic acid and derivatives thereof, ubiquinone and ubiquinol and derivatives thereof, vitamin C and derivatives (e.g. ascorbyl palmitate, Mg ascorbyl phosphate, ascorbyl acetate), tocopherols and derivatives (e.g. vitamin E acetate), vitamin A and derivatives (vitamin A palmitate), and also coniferyl benzoate of benzoin resin, rutinic acid and derivatives thereof, α-glycosyl rutin, ferulic acid, furfurylideneglucitol, carnosine, butylhydroxytoluene, butylhydroxyanisole, nordihydroguaiacic acid, nordihydroguaiaretic acid, trihydroxybutyrophenone, uric acid and derivatives thereof, mannose and derivatives thereof, zinc and derivatives thereof (e.g. ZnO, ZnSO4), selenium and derivatives thereof (e.g. selenomethionine), stilbenes and derivatives thereof (e.g. stilbene oxide, trans-stilbene oxide) and the derivatives (salts, esters, ethers, sugars, nucleotides, nucleosides, peptides and lipids) of these specified active ingredients which are suitable according to the invention.
The amount of the abovementioned antioxidants (one or more compounds) in the preparations according to the invention is preferably 0.001 to 30% by weight, particularly preferably 0.05-20% by weight, in particular 1-10% by weight, based on the total weight of the preparation.
If vitamin E and/or derivatives thereof are the antioxidant or antioxidants, it is advantageous to choose their particular concentrations from the range 0.001-10% by weight, based on the total weight of the formulation.
If vitamin A or vitamin A derivatives, or carotenes or derivatives thereof are the antioxidant or the antioxidants, it is advantageous to choose their particular concentration from the range 0.001-10% by weight, based on the total weight of the formulation.
Besides said ingredients, preparations according to the invention can comprise oils, waxes, lipids, emulsifiers, thickeners, skin moisturizers, UV filters, complexing agents, preservatives, perfume, powder raw materials, pigments, dyes.
For all this it is in individual cases possible that the above-mentioned concentrations given are slightly exceeded or not reached and nevertheless preparations according to the invention are obtained. In view of the widely scattered diversity of suitable components of such preparations, this comes as no surprise to the person skilled in the art, meaning that he knows that such excesses or shortfalls do not depart from the essence of the present invention.
The examples below serve to illustrate the present invention without limiting it. The numerical values in the examples are percentages by weight, based on the total weight of the particular preparations.
The coconut rope glove used is a standard commercial product, e.g. from Acca Kappa. A luffa sponge can also be used as massage belt and as large-pored make-up removal pad (e.g. from Wellsana).
For use, the skin surface to be treated is rubbed with the clean, dry or slightly moistened sponge a few times, for example 3× with slight pressure, for example with circular movements, similarly to washing the body with a flannel. The preparation is then rubbed into the surface of the skin. This is carried out like the normal application of a cream or lotion.
