Definitions

  • the invention relates to a pad based on cotton wool, having a basis weight of at least 150 g / m 2 , comprising two different faces and intended for skin care.
  • cotton wool pad includes everything product cut into a format which essentially comprises cotton fibers in a proportion ranging from 70 to 100 percent cotton fiber and 0 to 30 percent cotton artificial or synthetic fibers. These are for example fibers polyolefins hot-melt.
  • Skin care includes body care, facial care, and more particularly beauty treatments using cosmetic products: make-up removal and face makeup, baby care: toilet and change baby, etc.
  • cotton wool pads or products on the market are in the form of cut formats: round (commonly referred to as make-up discs), oval or square. They are often composed of a mixture of cotton fibers of different qualities or a mixture of cotton fibers and other fibers depending on the product sought or the manufacturing process used. They're from homogeneous composition throughout their thickness and have external structural faces and identical compositions. They are symmetrical.
  • Certain products marketed for cosmetic use have two sides different: they are two-sided. But the two sides are often distinguished essentially visually and not always functionally.
  • a first tampon (D) comprises a tablecloth consisting of a superposition carded sails, itself surrounded by two outer carded sails previously calendered. The association can be done by collage. The two sails exterior can be differentiated by the more or less important calendering and the case if necessary, by a printed motif.
  • a second buffer (E) consists of a sheet also consisting of a superimposition of card webs on which a hydrolied nonwoven is deposited, before cutting.
  • the hydrolied nonwoven is a mixture of artificial fibers and fibers synthetic and more precisely viscose and polyester.
  • European patent application No. 0 750 062 describes articles cleansing the skin, which are both gentle to the skin and sufficiently resistant to allow friction on the skin without causing irritation or lesions on the latter. The rubbing action allows the elimination of impurities and dead cells from the surface of the skin.
  • These articles include a nonwoven substrate, preferably hydrolyzed, having a grammage of 20 to 150 g / m 2 , characterized by a specific coefficient of friction.
  • the substrate preferably comprises at least in part long fibers capable of emerging from the main surface under the action of friction while remaining attached to the substrate. It can be composed of a mixture of hydrophilic and hydrophobic fibers or of purely hydrophilic or purely hydrophobic fibers.
  • At least one side of the substrate used essentially performs the function of cleaning the skin. It also serves as a support for cleansers or make-up removers such as lotions or toilet milks.
  • the nonwoven substrate is associated with other layers made of different materials. If the cleaning article consists only of the nonwoven substrate, the two faces of the article are identical and cannot be distinguished. The article is then similar to a dry wipe, the two faces of which can be used interchangeably for cleaning the skin.
  • French Patent No. 2,052,089 describes an element of wadding or cotton made up of at least two tablecloths of different qualities, held together either by padding, either by compression while remaining puffy and soft in contact with the skin.
  • One side is more particularly suitable for a make-up removal and the other face completes makeup removal.
  • the differentiation of the two faces is based here on the nature or quality of the two layers: they can be made of materials different or of the same material of different qualities. It is a product complex.
  • the applicant in its French patent application N ° 99 07612 not yet published describes a product made one hundred percent of cotton wool fibers comprising at least first and second outer layers, the first layer consisting of fine fibers with a low micron index forming a soft face and the second layer consisting of fibers having an index higher micronaire forming a cleaning face, called "scratching".
  • the faces are differentiate by the nature of cotton fibers.
  • the subject of European patent application No. 0 405 043 is a buffer for applying and / or removing liquid or semi-solid substances, comprising at least three superimposed layers of absorbent fibrous material such as cotton.
  • Each of the two outer layers is compressed by uniform tightening over the entire face layer and may have additional compression zones by marking a pattern.
  • the central layer is not compressed and forms the heart absorbent buffer.
  • the three layers are superimposed so as to form a sandwich structure.
  • the two external faces can have different patterns and be more or less compressed.
  • This product intended for the application of a cream or a liquid is not sufficiently resistant if it is used for make-up removal or skin cleansing. Indeed, friction forces are exerted on the skin with the pad moreover, supports a wetting product on its surface.
  • the cohesion between the layers is insufficient, due to the sandwich structure of the product: three separate layers superimposed and linked by their edges.
  • Another object of the invention is to provide a tampon where the two faces are differentiated without changing the nature of the cotton fibers or the quality of the cotton, the differentiation being made not only on the surface of the pad but for one of the sides in the thickness of the tampon.
  • the invention also aims to provide a resistant pad and keeping a good cohesion.
  • Another object of the invention is to provide a hydrophilic cotton pad having a basis weight of at least 150 g / m 2 which has two separate faces, one intended for skin care, in particular for cleansing the skin and to the application of cosmetic make-up or make-up removal products, and the other, softer and more absorbent, intended to absorb the excess of product applied.
  • the user can distinguish the faces in use: by touch, in contact with the skin or by applying skin care products, and also visually.
  • the invention further aims to obtain a tampon whose face intended for skin care, allows to receive aqueous cosmetic products in delaying their absorption and penetration into the buffer.
  • the invention also aims to provide methods of manufacturing these pads, simple, avoiding the preparation of cotton tablecloths of composition and complex structure.
  • the subject of the invention is a cotton wool pad intended for skin care, having a grammage of at least 150 g / m 2 and comprising two different external faces of which the fibers are linked.

  • the spacing e 1 between the ridges of the first face is between 1.2 and 5.5 mm and preferably between 2 and 4 mm.
  • the depth p of the streaks of the first face is at least 0.40 mm and preferably at least 0.50 mm.
  • At least 60 percent of the pad fibers are tied.
  • the first external face of the pad comprises a agent delaying the absorption of these aqueous products.
  • the invention also relates to methods of manufacturing the tampon. cotton wool according to the invention.
  • a first method consists in supplying a cotton tablecloth, hydrolying a first external face of the tablecloth by means of water jets whose axes are spaced from one another by a distance between 1 and 5.5 mm with a contribution in energy of at least 1.4 x 10 -3 kwh / m 2 , and hydrolyze the other external face of the water table by means of water jets whose axes are spaced by a distance between 0.4 and 1.2 mm with an energy input of at least 0.9 x 10 -3 kwh / m 2 .
  • a second method consists in providing at least two cotton tablecloths hydrophilic from bleached fibers laid or laundered, mark the first layer so as to print streaks with a spacing between streaks between 1 and 8 mm and a streak depth of at least 0.25 mm on one side of the first layer, the marking pressure being sufficient to obtain a buffer resistance of at least 20 N in the running direction and of at least 16 N in transverse direction according to the test method given in the description which follows, mark or consolidate the second layer, and associate the two layers thus obtained, the two marked and / or consolidated faces being located outside the tampon.
  • the tampon according to the invention is a cut product of round, oval, square or any other shape. It has a grammage between 150 and 400 g / m 2 and preferably between 180 and 300 g / m 2 . It is cotton-based and consists mainly of absorbent hydrophilic cotton fibers. More specifically, it comprises from 70 to 100 percent of cotton fibers of homogeneous quality and from 0 to 30 percent of artificial fibers such as viscose fibers, synthetic fibers such as polyester fibers, bicomponent fibers (polyester / polyester, polypropylene / polypropylene or polyester / polypropylene), or mixtures thereof.

  • the lint resistance of the first side of pads A was measured and state of the art buffers B, C, D, E and F using a method specific described below.
  • the pads are disc-shaped and have a diameter about 57 millimeters.
  • the method is to use a rubber finger mounted on a cylinder to simulate friction on the skin.
  • This finger is set in motion in order to come land on the surface of a tampon and move on its surface.
  • the first external face A1 has been tested as well as the second external face A2.
  • the mass of fibers is divided by 10 for the first face of the pads according to the invention, with respect to the mass measured for the buffers B, C, D and F.
  • the buffer E has a lint-free side due to the presence of the nonwoven, but another side excessively fluffy compared to the second side of the pad according to the invention. The reduction in linting is therefore very significant for the tampon according to the invention.
  • the mass of commonly used disc-shaped cotton pads varies between 0.5 and 0.7 grams.
  • the fibers recovered from the first face (A1) of the five buffers A according to the invention therefore correspond to 0.1% of the mass of the buffer A.
  • the fibers recovered from the five each of types B, C, D and F of the state of the art amount to 1% of the mass of corresponding buffers.
  • the first side of the tampon therefore has a new structure, providing advantageous properties.
  • the tampon according to the invention has numerous advantages in use.
  • the first side is used to apply skincare products to the skin.
  • the product is applied cosmetic on the first side of the pad then we pass this first side on the skin or face.
  • the structure of the first face comprising ridges advantageously forms a relief in relief and in bump.
  • the surface in contact with the skin is more limited due to the relief.
  • the prominent bump part increases the pressures on the skin and the forces friction. The friction effect thus obtained improves cleaning.
  • the hollow parts form an additional reserve of available product.
  • the same hollow When the tampon passes over the skin, the same hollow first fills for function that of the product reservoir which comes to spread in contact with the pad on the skin, under the application pressure, then that of an impurity collector at during the displacement of the tampon on the skin. Cleaning done by the first passage is thus optimized.
  • the displacement of the tampon on the skin is preferentially made perpendicular to the striations of the first face.
  • the second side is used to absorb impurities, excess product and traces of makeup that remain on the skin.
  • the product does not deform, it has an excellent grip.
  • the solvent that conventionally penetrates the tampon is less absorbed in depth and is more easily restored during cleaning, thanks to the more compact on the first side of the pad and with fibers tightened in the thickness of the buffer.
  • the solvent is thus used more effectively to dissolve the varnish covering the nails.
  • the relief of the first face in contact with the skin has a massaging effect during passage of the tampon and provides a relaxing effect for the skin.
  • the first external face may include an agent delaying the absorption of these products allowing to temporarily keep the products applied on the surface of the tampon without them getting inside the tampon.
  • the absorption delaying agent is a component based on softeners or waxes or a component that attaches to the fibers.
  • softeners are fatty amines, fatty alcohols, fatty esters, fatty polyethylenes or polyamides or their mixtures.
  • the components which attach to the fibers are, for example, metal salts stearic acid complexes, perfluorinated derivatives, zirconium salts or silicones.
  • the wax-based components are emulsions of waxes and paraffins or wax emulsions alone.
  • the agent is a natural wax emulsion, of mineral origin, vegetable or animal.
  • animal wax examples include spermaceti wax and wax bee.
  • plant-based wax examples include candellila wax and carnauba.
  • wax of mineral origin examples include ceresin and azocerite.
  • the beeswax emulsion is particularly advantageous and suitable for cosmetic use of the tampon. It is a dermatologically tested component. It's about a cationic bleached beeswax emulsion which comprises beeswax, water, emulsifying agents, glyceryl stearate and diethanolaminoether stearate.
  • the beeswax itself is composed of esters of waxy fatty acids such as myricyl palmitate, cerotic acid and other homologous waxy acids and small amounts of hydrocarbons, cholesterol esters and ceryl alcohols.
  • the agent delaying absorption is an emulsion or dispersion comprising at least minus 30% of active ingredients.
  • the first face of the cotton product or pad according to the invention comprises at least 1 g / m 2 of applied emulsion, that is to say at least 0.3 g / m 2 of active ingredients deposited.
  • the first face comprising on the surface such an agent acquires very advantageous.
  • a simple test highlighting this property consists in depositing on the surface a container filled with water, at room temperature (around 20 °), tampons as well treated according to the invention, the treated side facing outwards and the face absorbent towards water, and prior art buffers B and C. The first ones remain on the surface for at least 5 minutes, the others almost soak up water instantly and are very quickly submerged, usually after 3 to 5 seconds.
  • the advantage thus obtained is to be able to keep the products on the surface more for a long time and use the total amount of product deposited on the tampon to skin care, without loss of product and without deformation of the tampon.
  • a test of internal use at the requesting company was carried out by 25 people usually and exclusively using cotton wool pads C for skin care, make-up removal, etc ...
  • a pads according to the invention, the first side of which has been treated with an agent delaying absorption, have been tested compared to tampons according to the invention the first side of which has not been treated and with C buffers of the state of the art.
  • the pads according to the invention For the pads according to the invention, the first side of which has not been treated, 50% of people noted a delay in the absorption of the care products deposited in surface of these pads. This is explained by the specific structure of the first face pads according to the invention. In fact, the fibers are more tight in thickness buffer.
  • the pads according to the invention As for the pads according to the invention, the first face of which has been treated, almost all people: 92%, noted this capacity of the buffer to delay absorption of skincare products.
  • a first technique consists in differentiating the two faces of the tampon by hydrolizing each of the faces according to different parameters.
  • a first method consists in manufacturing by layering at least two layers of cotton fibers forming the two outer layers. These sheets may be of the same or different fiber quality. They can be made directly from hydrophilic and bleached cotton. They can also be obtained from unbleached raw cotton, then chemically treated to obtain hydrophilicity and bleaching. They are then superimposed and associated by any known means such as bonding means or mechanical means such as calendering or needling. The means of association can also be hydraulic.
  • a good association can be obtained by impregnating the layers superimposed by any known conventional means such as passing through a bath impregnation, spraying, spilling a solution.
  • This impregnation is associated with an expression compacting the water table and eliminating part of the quantity liquid contained in the wet sheet, for example by calendering or passing over a vacuum slot.
  • a second method consists in preparing a layer of cotton fibers by pneumatic and to lay this tablecloth between two cotton card sails.
  • a continuous method of manufacturing and associating plies is described by the patent European No. 0 681 621 in the name of the plaintiff.
  • the hydroliage technique makes it possible to combine the layers or both tablecloths together, and to bind the surfaces of the tablecloth.
  • the hydroliage is carried out at by means of high pressure water jets combined with vacuum expression, by means of of a device marketed by ICBT-PERFOJET, Grenoble, France.
  • the two hydroliage stages corresponding to the treatment of each of the two external faces of the product, can intervene, in the case of an unbleached fiber which is going to be chemically treated, just after the impregnation step of the web as is described in European patent application No. 0 735 175. They can also be placed in the final rinsing phase according to European Patent No. 0 805 888 in the name of the plaintiff.
  • the advantage here whatever the process, is to differentiate the faces by hydroliage, directly online.
  • the two external faces are hydroleumed according to different parameters one after another on endless canvases or cylinders.
  • the hydroliaging device includes a high pressure pump supplying an injector placed transversely to the running of the sheet or layer of fibers, over its entire width.
  • the injector consists of a volume of pressurized water, closed by a blade of steel which is perforated with calibrated holes producing jets in the form of fines high pressure water needles projected perpendicular to the surface of the face external.

If the position of the injector is fixed and the layers of cotton running under it, there is a series of parallel streaks or grooves on the surface of the product corresponding to the passage under the jets.
  • the pressure exerted is high, at least 40 bars, preferably between 50 and 80 bars so as to dig deep streaks or grooves in the product.
  • the energy input is at least 1.4 x 10 -3 kwh / m 2 and can vary between 1.4 x 10 -3 and 2.5 x 10 -3 kwh / m 2 depending on speed, pressure, hole diameter and spacing between holes.

  • the streaks obtained on the surface of the second face are much finer and shallow.
  • the second external face has a less compact appearance, a soft and absorbent surface. It does not present reliefs visible to the naked eye, in hollow and bump.
  • Additional differentiation can be made by printing by marking of the different patterns of the existing streaks on the first face.
  • a second technique for manufacturing the tampon according to the invention consists in differentiate the two sides of the stamp by marking.
  • Two tablecloths are prepared from bleached fibers laid in tablecloth or bleached tablecloths. They are then each marked passing between a cylinder engraved with a relief motif and a smooth counterpart to print this motif in the thickness of the tablecloth and form a hollow and more or less relief in relief deep on the surface of the sheets which will correspond to the external faces of the pad.
