Patent Application
20070110792
The present invention relates to cosmetic or dermatological articles comprising at least one medium, and at least one cosmetic composition carried by the medium.
Articles comprising a flexible medium that is insoluble in water, and a cosmetic composition that is carried by the medium, also known as “wipes”, are in widespread use, in particular for removing makeup.
Wet wipes that are impregnated with a latherable water-based composition are thus known from publications WO 02/092050, WO 02/092052, WO 02/092052, and U.S. Pat. No. 6,287,757, amongst others.
U.S. Pat. No. 4,303,543 discloses dry wipes that are impregnated with a latherable composition during manufacture, and then dried after impregnation.
Publication WO 00/07561 describes two-layer sponges containing a quantity of latherable powder.
Known wipes or sponges comprise a medium constituted by a substrate that is insoluble in water, and they are a source of solid waste.
U.S. Pat. No. 6,818,603 discloses a block of soap incorporating fibers which can be water-soluble.
U.S. Pat. No. 6,576,575 describes an adhesive dressing comprising fibers that are soluble in water.
In one of its aspects, the invention relates to a cosmetic or dermatological article comprising:
a medium in the form of at least one sheet of a material that is soluble in water at a temperature lower than 20° C.; and
at least one cosmetic or dermatological compound carried by the medium.
The terms “sheet” and “layer” should be understood as being synonymous.
In another of its aspects, the invention also provides a cosmetic or dermatological composition in fluid form that is obtained by dissolving, in water, a medium in the form of at least one sheet of a material that is soluble in water, and carrying at least one cosmetic or dermatological compound.
The term “fluid” should be understood as “able to flow under the effect of its own weight”.
In another of its aspects, the invention also provides a cosmetic or dermatological treatment comprising:
forming a cosmetic or dermatological composition by dissolving, in water, a medium comprising:
applying the composition formed in this way to the human body, e.g. to keratinous materials.
The cosmetic treatment may comprise applying makeup.
In another of its aspects, the invention also provides a cosmetic article comprising:
at least one cosmetic composition; and
at least one sheet of fibers that are soluble in water, preferably at a temperature lower than 20° C., the density of the sheet being not greater than 0.1 grams per cubic centimeter (g/cm3).
The invention also provides a cosmetic article comprising:
at least two layers defining a cavity between them, with at least one of the layers being soluble in water; and
at least one cosmetic composition inside the cavity.
In another of its aspects, the invention also provides a kit comprising:
packaging; and
at least one article as defined above. The packaging may include a colored indicator that is representative of the color of the composition.
In another of its aspects, the invention relates to a non-adhesive and preferably flexible cosmetic or dermatological article comprising:
at least one medium that is soluble in water, preferably completely soluble in water, and more preferably, soluble at a temperature lower than 20° C.; and
at least one cosmetic or dermatological compound carried by the medium.
The medium may carry a cosmetic or dermatological composition.
By way of example, the cosmetic composition is contained in the medium or secured thereon.
The term “soluble in water at a temperature lower than 20° C.” should be understood as dissolving in water at a temperature lower than 20° C. by manually agitating and/or rubbing the medium if necessary, over a period of time that is typically less than 5 minutes (min), preferably less than 1 min, and more preferably less than 30 seconds. The invention does not exclude water at a temperature that is higher than 20° C. from being used to dissolve the medium.
The term “flexible” should be understood as an article that is capable of being compressed or flexed without rupturing, and that is capable of being adapted to the contours of the human body. In some embodiments, a flexible article made in the form of a fibrous sheet may be folded in half at least once, without breaking into two pieces.
By way of example, the article is for single use only.
The invention may present the advantage of reducing the quantity of solid waste produced by the consumer.
An article made in accordance with the invention may also offer additional appeal associated with it changing its appearance in use as a result of the medium dissolving, and this may please young children in particular, and encourage them to wash their hands or clean their teeth more often or more thoroughly.
The invention may also offer novel possibilities for packaging and formulating numerous products, e.g. cosmetics, hygiene products, or care products for the skin, the lips, the mouth, or hair.
The invention may also make it possible to package cosmetic compositions in powder form that do not lend themselves well to conventional packaging methods, such as compacting them in a dish or incorporating them in a paste, for example.
The invention may also make it easier to package cosmetic compositions in paste or powder form that are difficult to take manually.
The article may comprise a composition for the hair, in particular a shampoo, a conditioner, or a hair-conditioning treatment.
The composition may represent between 10 and 1000% by weight, relative to the weight of the medium.
Medium
The medium may be in the form of one or more non-fibrous films that are obtained by evaporating a solvent, for example, but the medium preferably includes interlocking fibers that are soluble in water, preferably at a temperature lower than 20° C.
In an embodiment of the invention, the medium comprises at least one layer of a non-woven fabric that is constituted essentially by fibers that are soluble in water, preferably at a temperature lower than 20° C. and may comprise at least a layer of a substrate that is insoluble in water.
Once wet, the medium may be substantially non-shrink.
When the medium comprises a non-woven fabric, any technique that is suitable for making a non-woven fabric from fibers may be used in order to manufacture the medium.
For example, the fibers may be formed by extrusion and disposed on a conveyor so as to form a sheet of fibers that is then colsolidated by a conventional fiber-bonding technique, e.g. needling, heat-bonding, calendering, or air through bonding, a technique in which the sheet passes into a tunnel into which hot air is injected. The air through bonding technique is advantageously used when the sheet is constituted by dual-component fibers, e.g. fibers comprising at least two grades of polyvinyl alcohol (PVA) having melting or softening points that are different, the fibers being co-extruded, for example, so that the fiber is constituted by at least one first grade located at the core of the fiber, and by at least one second grade located at the periphery of the fiber, in the form of a sheath. The fibers can thus be bonded more easily when the sheath presents a melting point that is lower than the core.
The sheet of fibers used for manufacturing the non-woven fabric can also be formed of carding fibers that are cut to a length lying in the range 10 millimeters (mm) to 50 mm, and then by depositing the fibers on a conveyor where the sheet can then be consolidated by a bonding technique as described above.
The density of the medium depends on its applications. The medium may present a density that is optionally not greater than 0.1 g/cm3, for example. A density that is not greater than 0.1 g/cm3, better in the range 0.01 g/cm3 to 0.1 g/cm3, can make it very loose, and make it easier to dissolve in water.
In an embodiment, the medium comprises at least two layers of non-woven fabric that are each constituted essentially by fibers that are soluble in water, preferably at a temperature lower than 20° C.
By way of example, the two layers are assembled together at their peripheries, as shown in
The medium may also comprise only one layer of water-soluble fibers, and a cosmetic or dermatological composition may, for example, be dispersed within the layer, or may cover it on one of its surfaces only.
In
In the embodiments in
The medium may also present a shape that generally is not flat, presenting the appearance of a mass, as shown in
In an embodiment of the invention, the article formed by the cosmetic or dermatological composition and by the medium is intended to be put into contact with water before it is used. Thus, the medium is initially dissolved completely before the article is applied to the human body. Depending on the quantity of water that is added to the article in order to dissolve the medium, it is possible to adjust the apparent viscosity of the composition obtained.
In a variant embodiment of the invention, the article formed by the cosmetic or dermatological composition and by the medium is intended to be put into contact with water before it is used, but the medium is put into contact with a region of the human body, e.g. the skin, or hair, before it is completely dissolved, or even before it is wetted. Depending on the quantity of water that is added, this makes it possible, for example, to modify its properties as a function of the desired result. Water can be poured onto the article while said article is not in contact with the body. Alternatively, the body can be wet, or water can be sprayed or poured onto the medium while the article is in contact with the region to be treated.
In still another embodiment of the invention, the article is designed to be used without being impregnated with water. In this event, and if so desired by the user, the medium may be dissolved only after it has been used, by being disposed at the bottom of a washbowl, and by running water thereon, for example. By way of example, the article is pre-impregnated with the composition, or the user can deposit the composition thereon.
In particular, when the medium is not intended to be completely dissolved in water prior to application, the shape of the medium may depend on the region of the body to be treated.
at least one medium presenting a multilayer structure with:
By way of example, and as shown in
By way of example, the substrate 20 is a sheet of a non-woven synthetic fabric, e.g. a non-woven fabric of polyethylene, polypropylene, polyethylene terephthalate (PET), polylactic acid, polyamide, viscose, or cellulose fibers, or a mixture of these fibers . . . , or a film, that is optionally permeable. Non-woven fabrics are described in general manner in RIEDEL “Nonwoven Bonding Methods & Materials” Nonwoven World (1987), incorporated herein by reference.
By way of example, a multilayer structure with at least one layer formed by a substrate that is insoluble in water can be useful for making an article 22 including a medium 23 in the form of a finger of a glove, as shown in
The layer 20 of insoluble substrate can also be in the form of a glove or of a mitten.
When the medium comprises a plurality of layers, the various layers may be assembled together in many ways, e.g. by heat-sealing, adhesive, or stitching, irrespective of whether or not said layers are all made out of water-soluble fibers, and where appropriate, the layers may constitute one or more cavities containing one or more cosmetic or dermatological compositions, or a plurality of components of a single cosmetic composition that are to be mixed together extemporaneously. During assembly by stitching, it is possible to use a thread that is itself water-soluble, where appropriate.
Water-Soluble Fibers
As indicated above, the medium may comprise, or may even be constituted essentially by fibers that are soluble, preferably in water at less than 20° C.
By way of example, the medium may thus include more than 95% by weight, indeed more than 99% or even more, of water-soluble fibers.
The fibers are preferably made out of polyvinyl alcohol (PVA) by using a method that imparts the desired solubility thereto.
Fibers that are soluble in water at a temperature lower than 20° C. are sold by the Japanese company KURARAY under the trade name KURALON K-II WN2. The method of manufacturing such fibers includes the use of organic solvents. The fibers may be substantially circular in section.
European application EP 0 636 716, the content of which is incorporated herein by reference, describes PVA-based water-soluble fibers and their method of manufacture.
The invention is not limited to the use of PVA, and fibers made out of other water-soluble materials may be used, providing they dissolve in water at the desired temperature, e.g. polysaccharide fibers sold under the trade name LYSORB by LYSAC TECHNOLOGIES, INC, or starch hydrolysate polymer-based fibers such as glucomannan or starch.
Where appropriate, the medium may include a mixture of fibers that are soluble in water at various temperatures.
The fibers may be composite, and may, for example, comprise a core and a sheath that are not of the same type, e.g. that are formed of different grades of PVA.
The medium could have substantially no fibers that are insoluble in water.
In an aspect of the invention, the medium does not have any adhesive, in particular any pressure-sensitive adhesive.
Cosmetic and Dermatological Compounds
Very diverse compounds may be used in an article made in accordance with the invention.
By way of example, they may be compounds used for makeup, for care, and/or for hygiene, and/or for cleaning the skin, the mouth, the lips, hair, or the nails.
The cosmetic or dermatological composition carried by the medium may represent between 10% and 1000% by weight relative to the weight of the medium, for example.

The article may include other film-forming agents, which should be selected as a function of the nature of the medium, for example.
The other film-forming agents may be selected from synthetic polymers of the radical or polycondensate type, polymers of natural origin, and mixtures thereof.
The radical type film-forming polymers may, for example, be vinyl polymers or copolymers, in particular acrylic polymers.
The vinyl film-forming polymers may be obtained by polymerizing monomers with an ethylenically unsaturated bond containing at least one acid group and/or esters of said acid monomers and/or amides of said acid monomers, such as α,β-ethylenically unsaturated carboxylic acids.
Examples of film-forming polycondensates that can be mentioned include polyurethanes, polyesters, polyester amides, polyamides, and polyureas, this list not being limiting.
Polymers of natural origin, which may optionally be modified, may be selected from shellac resin, gum sandarac, dammar resin, gum elemi, copal resins, cellulose polymers.

Ways of Incorporating the Cosmetic or Dermatological Compound(s) in the Article
At least one cosmetic or dermatological compound, and more generally the cosmetic or dermatological composition, may optionally be present on the outside of the article.
When the composition is present on the outside of the article, said article can be used by being brought into contact with the region to be treated, for example, so as to enable the composition to be transferred. Where appropriate, said transfer can be performed by rubbing the article on the region to be treated.
When the composition is present on the outside of the article, said article need not be wet while it is being used, and the medium is dissolved only after it has been used.
When the composition is present on the outside of the medium, the article may, in some cases, nevertheless be wet while it is being used, e.g. so as to modify the properties of the composition, improve the transfer of the composition, or form a film-forming substance.
When the composition is not present on the outside of the article, it may be necessary to dissolve the medium, at least in part, or even completely, before use.
At least part and possibly even all of the composition may be present inside the article in powder form, in particular in the form of a substantially anhydrous powder. The article may be dry to the touch, for example. The grain size of the composition should be selected as a function of the porosity of the medium so as to reduce losses when shaken.
When the composition is a powder, it may be contained in a cavity in the medium, e.g. formed between two layers thereof, as in the embodiment in
The composition need not be a powder but could be a creamy or pasty liquid forming a paste, for example. In this event, the composition may include one or more solvents, for example, that are compatible with the nature of the medium, in particular non-aqueous solvents, so as to prevent it from dissolving prematurely, such as inferior alcohols including 1 to 6 carbon atoms, such as ethanol; polyols such as glycerine; glycols such as butylene glycol, isoprene glycol, hexylene glycol, propylene glycol; polyethylene glycols, such as PEG-8, sorbitol; animal hydrocarbon oils, such as perhydrosqualene; vegetable hydrocarbon oils, such as glycerol or fatty acid mono-, di-, or tri-ester glycerides, e.g. sweet almond, sunflower, corn, soybean, nut, or apricot kernel oils; synthetic triglycerides, such as those sold by Stearineries Dubois, or those sold under the trade name Miglyol 810, 812, and 818 by Dynamit Nobel; synthesized esters and ethers, in particular fatty acids, such as oils of formulae R1COOR et R1OR2 in which R1 represents the fatty acid residue including 8 to 29 carbon atoms, and R2 represents an optionally-branched hydrocarbon chain containing 3 to 30 carbon atoms, such as Purcellin oil, isononyl isononanoate, 2-octyldodecyl stearate, isostearyl lactate, octylhydroxystearate, or tri-isocetyl citrate, for example; polyol esters, such as propylene glycol dioctanoate, diethyleneglycol di-isononanoate; and pentaerythritol esters; linear or branched hydrocarbons of mineral or synthetic origin, such as volatile or non-volatile paraffin oils; fatty alcohols having 8 to 26 carbon atoms, such as cetylic alcohol, stearyl alcohol, and mixtures thereof (cetearyl alcohol), octyldodecanol, 2-hexyldecanol; alkoxylated fatty alcohol, and in particular ethoxylated fatty alcohol, such as oleth-12 or ceteareth-20; partially fluorinated hycrocarbon and/or silicone oils such as those described in document JP-A-2-295912. Suitable fluorinated oils that can also be mentioned are perfluoromethylcyclopentane and 1,3-perfluorodimethylcyclohexane, sold under the trade names “FLUTEC PC1®” and “FLUTEC PC3®” by BNFL Fluorochemicals; perfluoroalkanes such as dodecafluoropentane and tetradecafluorohexane, sold under the trade names “PF 5050®” and “PF 5060®” by 3M; silicone oils such as volatile or non-volatile polymethylsiloxanes (PDMS) having a linear or cyclic silicone chain, which may be liquid or pasty at ambient temperature, in particular cyclopolydimethylsiloxanes (cyclomethicones) such as cyclohexasiloxane; polydimethylsiloxanes comprising alkyl, alcoxy, or phenyl groups, pendant or at the end of a silocone chain, groups having 2 to 24 carbon atoms; phenyl silicones such as phenyltrimethicones, les phenyldimethicones, phenyltrimethylsiloxydiphenyl-siloxanes, diphenyl-dimethicones, diphenylmethyldiphenyl trisiloxanes, 2-phenylethyltrimethyl-siloxysilicates, and polymethylphenylsiloxanes.
The term “hydrocarbon oil” in the list of oils mentioned above means any oil containing mainly hydrogen and carbon atoms, and optionally the following groups: ester, ether, fluorine, carboxylic acid, and/or alcohol.
The composition could contain a certain quantity of water when it is impregnated in the medium. In order to prevent it from dissolving prematurely, the water that is introduced into the medium during its impregnation is eliminated by conventional means used to dehydrate compositions containing water, e.g. by heating.
The composition may be deposited on only one surface of the medium, the other surface of the medium being used for holding the article, for example.
For a colored composition, the article is packaged in a packaging such as a box 30, for example, as shown in
When the composition is incorporated in the article during its manufacture, the article is packaged loosely in a box or in individual packaging. Where appropriate, the articles are packaged in a string. The articles may also be folded in half and interfitted, so that removing one article brings the next into a configuration making it easy to grasp.
When the composition must be deposited on the medium by the user, the composition and the medium may be proposed in the form of a kit, for example. By way of example, the composition is supplied in a quantity that is sufficient to enable a plurality of doses to be dispensed on a set of mediums that are intended to be used successively.
Applications in Applying Makeup/Compositions that are Transferable Merely by Making Contact with or Rubbing Against the Skin, the Lips, or Hair
A medium is made by cutting out an egg shape, that is about 5 cm long and 1.5 cm wide, from a sheet of KURALON K-II WN2 that is about 0.5 mm thick and that weighs 60 grams per square meter (g/m2).
Depending on the desired intensity of the makeup, the medium is impregnated with a quantity, lying in the range 0.02 g to 0.1 g, of the following colored powder composition, deposited on a surface thereof.
The medium impregnated in this way is soft to the touch and easy to hold, in particular by its surface that is opposite from the surface carrying the composition, and it can be displaced on the skin so as to enable the composition to be transferred thereto.
After use, the medium is easily eliminated under running water.
The medium can be impregnated while it is being used, or the medium can be proposed to the user pre-impregnated, in particular in an individual packaging.
A medium is made by cutting out a round shape, that is about 5 cm in diameter, from a sheet of KURALON K-II WN2 that is about 2 mm thick and that weighs 80 g/m2.
The medium is impregnated with 0.1 g of the following powder composition, deposited on a surface thereof.
After use, the medium is easily eliminated under running water.
The same medium as in Example A is coated in 0.25 g of the following anhydrous cream-blusher composition:
After use, the medium is easily eliminated by dissolving in cold water.
Applications in Applying Makeup/Articles Having a Medium that is Dissolved Before Being Applied
An article such as the article shown in
In order to use the article, said article is disposed in the hollow of the hand and water is poured onto the medium.
The PVA fibers contribute to texture the composition and/or impart film-forming properties thereto. The user can influence the texture of the substance by adding more or less water.
The substance formed in this way can be spread directly onto the body or the face by means of the fingers or by using an applicator, e.g. a flocked endpiece, such as a foam, a felt, or cotton wool, or a brush.
Applications for Hygiene and/or Care Purposes
An article is made comprising a medium constituted by a disk, that is 7 cm in diameter, of a 2 mm thick sheet of KURALON K-II WN2 fibers weighing 80 g/m2, and that is impregnated with 0.2 g of a powder deodorant composition having the following formulation:
The article is used dry by wiping over the armpits.
The affinity of the medium for water makes it possible to wipe away any possible residues of transpiration.
An article such as the article shown in
In order to use the article, said article is disposed in the hollow of the hand and about 3 cubic centimeters (cm3) of water is poured thereon.
Said article is stirred by means of the index finger of the other hand, adding up to 3 cm3 to 6 cm3 of water if necessary, so as to obtain a uniform lather after the medium has completely dissolved.
The lather can be used to wash the hands or the face, for example.
A wipe is made as follows:
A square sheet having sides of 10 cm, a weight of 60 g/m2, and a thickness of 1 mm, is cut out of KURALON K-II WN2, and is impregnated with 0.9 g of the following concentrated latherable composition:
This composition contains at least 15% water. It is in the form of a paste that is deposited on the medium using conventional means, such as rolling, for example.
The composition is dried, and once dry said composition adheres to the fibers.
Once dry, the medium is calendered between rollers so as to densify it, stiffen it, and reduce its surface porosity.
In order to use the article, the wipe is passed under water, then rubbed so as to create the lather and dissolve the medium.
An article for use in shaving is made with the same medium as that in Example E, the composition of Example E being replaced as follows:
This composition contains at least 15% water. It is in the form of a paste that is deposited on the medium using conventional means, such as rolling, for example.
The composition is dried, and once dry said composition adheres to the fibers.
Once dry, the medium is calendered between rollers so as to densify it, stiffen it, and reduce its surface porosity.
In order to use the article, said article is applied to the already moistened cheeks, then it is rubbed while gradually adding water.
A makeup-remover compress for removing makeup from the face is made with the same medium as that in Example E, the composition of Example E being replaced as follows:
The composition is anhydrous, it is impregnated into the medium using conventional means, such as applicator rollers or impregnation strips, for example.
A makeup remover emulsion is generated by passing the sheet over the wet face, or better by rubbing it in the hollow of the hand with a small amount of water.
