AQUEOUS COMPOSITION BASED ON ALCOHOL, SURFACTANT AND SOLUBILIZING AGENT, IMPREGNATED ARTICLE OF THIS COMPOSITION AND HAIR CLEANING METHOD
DESCRIPTION OF THE INVENTION The subject of the present invention is a hair composition intended for hair cleaning comprising, in a cosmetically acceptable aqueous medium, at least one C2-C4 mono alcohol, at least one surfactant and at least one agent solubilizer of liposoluble compounds and a method of cleaning the latter using this composition. The hair has the tendency to lose certain of its qualities under the action of factors such as natural re-greasing, sweat, scale removal, pollution, humidity and others. These factors impair the visual appearance and the touch of the hair. Thus, re-greasing (and eventually contamination) overloads the hair, which has the tendency to form in packages. The hair is so difficult to comb, it has an unpleasant oily brilliance and an equally unpleasant touch. The importance of the consequence of these almost all inevitable factors is very variable. It depends, for example, on the quality of the hair, on its length and on the hairstyle adopted.
Whatever it is, to fight against these REF: 160700 inconveniences, shampoos are used. Indeed, washing with detergent compositions is very effective, it allows to eliminate stains, films. It is then possible, in the drying, to place the hair again in the desired shape. However, the beneficial effect of the shampoo vanishes and the problems described above are found in a few days. Consequently, it has a tendency to increase the frequency of shampoos. To make an application of shampoo, it is necessary to have a source of water, preferably hot or warm. The shampoo compositions are based on significant amounts of surfactants that can cause discomfort such as itching at the level of the scalp or eyes. To clean the hair more quickly and avoid moistening the hair, it has already been proposed to use shampoos called "dry". This technique involves spraying absorbent particles in the hair and then actively brushing the hair to remove the particles. However, in general, the complete removal of the particles is very difficult to obtain. The results are not satisfactory: the brilliance of the hair is reduced and the touch is rough. The object of the present invention is in particular to solve the problems mentioned hereinabove. More precisely still, the present invention seeks to propose a hair cleaning method that leads, at the end of the operation, to hair that has a neutral touch and visual appearance. Now, after important investigations carried out in the matter, it has now been found and this inadvertently and surprisingly, that this object and others could be obtained by applying liquid cosmetic compositions in particular hair, intended for cleaning the hair that they comprise in a cosmetically acceptable aqueous medium: from 10 to 90% by weight, in proportion to the total weight of the composition of at least one C2-C4 monoalcohol, from 0.01 to 5% by weight, in proportion to the total weight of the composition. composition of at least one surfactant selected from among anionic surfactants, amphoteric and / or zwitterionic surfactants and nonionic surfactants, from 0.01 to 5% by weight of an agent that solubilizes the liposoluble compounds other than the surfactants and chosen from linear hydrocarbons or branched, hydrogenated or non-hydrogenated polyolefins, volatile silicones and their mixtures, from 1 to 89.98% water. The clean hair with the compositions according to the invention possess own hair characteristics: the touch is natural, the hair is shiny (the fatty aspect has disappeared), the hair is aerated, lightweight and has no movies. In addition, the hair is more ordered, more flexible, more smooth. On the other hand, the treatment removes bad odors. Also, the subject of the invention is still the cosmetic use of a cosmetic composition as defined hereinabove for hair cleaning. The subject of the present invention is also a hair cleaning method, the method is characterized in that a composition as defined hereinabove is applied to dry hair, then the hair is dried.

It may eventually also contain conservatives. The amounts of the different constituents of the compositions according to the invention are those conventionally used in the fields considered. Of course these adjuvants must be of a nature and used in such quantity that they do not alter the cleaning of the hair according to the invention. The amount of these adjuvants can be, for example, from 0.01 to 30% by weight in proportion to the total weight of the composition. The composition may also contain an additive chosen from among preservatives, pH regulating agents, perfumes.

The compositions according to the invention are prepared according to techniques well known to those skilled in the art. The application of the composition can be done with the hands, with an applicator tip, with a vaporizer, with a distributor comb and preferably with an insoluble substrate impregnated with the composition. It has been found that the use of an insoluble substrate to apply the composition gives particularly interesting results. Thus, according to a preferred mode of the invention, the compositions according to the invention can also serve for the impregnation of water-insoluble substrates to constitute articles and in particular canvases or gloves intended for cleaning hair. The water-insoluble substrate can comprise one or more layers and can be chosen from the group comprising woven materials, non-woven materials, foams, sponges, wadding, sheets, balls or films. It can be, in particular, a non-woven substrate based on fibers of natural origin (linen, wool, cotton, silk) or of synthetic origin (cellulose derivatives, viseose, polyvinyl derivatives, polyesters such as polyethylene terephthalate, polyolefins such as polyethylene or polypropylene, polyamides such as Nylon, acrylic derivatives). Nonwovens are described in general in RIEDEL "Nonwoven Bonding Methods &; Materials ", Nonwoven World (1987) .These substrates are obtained according to the usual methods of the non-woven preparation technique.When the substrate is a non-woven, it is preferred to use a non-woven substrate, which can be It must be absorbent, soft on at least one face to remove make-up from the eyes in particular.As suitable non-wovens, for example, those can be cited. marketed under the names Ultraloft 15285-01, Ultraloft 182-008, Ultraloft 182-010, Ultraloft 182-016 by the company BBA, Vilmed MI519 Blau, Vilmed M 1550 N and 112-132-3 by the company Freudenberg, that marketed under the name Norafin 11601-010B by the company Jacob Holm Industries, that marketed under the name Aquadim VE50 GINL (spun lace) by the company Tharreau, the flocculated nonwovens marketed under the name Unile 109 and Univel 119 by Uni Flockage.
On the other hand, this substrate may comprise one or more layers having identical or different properties and having properties of elasticity, softness and other properties of intended use. The substrates may comprise for example two parts having different elasticity properties as described in WO-A-99713861 or comprise a single layer with different densities as described in WO-A-99/25318 or comprise two layers. of different textures as described in WO-A-98/18441. This article is preferably a bridge but can also have another shape (canvas for example). The subject of the invention is also an article comprising a water insoluble substrate and a composition as defined hereinabove impregnated in the substrate. The subject of the invention is also the use of the composition as defined hereinabove for the preparation of an article intended for hair cleaning. According to another aspect of the present invention, a single-use cosmetic article comprising at least one substrate impregnated with a liquid cosmetic composition as defined hereinbefore is made, the substrate is permeable and comprises at least one first group of fibers and at least one second group of fibers wherein the hydrophilicity is different from that of the fibers of the first group, those of the first and second group of fibers are arranged in such a way that a first face of the substrate has a hydrophilicity superior to the hydrophilicity of a second face of the substrate, opposite to the first, the first face is external to the substrate so as to come into contact with a surface to be treated, in particular the hair. With such an article, the gain in efficacy of a cosmetic treatment can be substantially improved by allowing a greater release, a larger amount on the surface to be treated, of the composition that is impregnated into the article. By "permeable" is meant a substrate apt to be covered throughout its thickness by the cosmetic composition. Thus, contrary to certain articles of the prior art in which reference is made above, the article according to the invention does not comprise any impermeable layer capable of forming a barrier to the composition that impregnates it. Of course the substrate is insoluble in water, that is to say that its integrity is not substantially affected by the presence of the aqueous cosmetic composition that it impregnates and this during at least the entire life of the product. Advantageously, the substrate is monolayer. By "monolayer substrate" is meant a substrate or all the fibers that compose them that are bound to each other during the same binding method. At the end, in the thickness of the substrate, the distribution of 2 types of fibers is not homogeneous and could be according to a profile characterized by: a majority of fibers of the first group on the first face of the substrate; a majority of fibers of the second group on the second face of the substrate and between the two faces; a relative amount of fibers of the first group that varies according to a relatively progressive profile where the slope is of opposite sign to that of the relatively progressive profile corresponding to the amount of relative fibers of the second group. Such a structure differs from multilayer structures in which different layers are formed and bound separately, then glued together by thermo-bonding, heat welding or ultrasound. Advantageously, the first face of the substrate has a relaxation index under static pressure (IRSPS1), the second face of the substrate has a relaxation index under static pressure (IRSPS2), the ratio IRSPS1 / IRSPS2 is greater than or equal to 1.5 RELAXATION INDEX UNDER STATIC PRESSURE (IRSPS); The test that will be described later in the present allows to measure the relaxation index under static pressure (IRSPS) of two faces of an article impregnated with a cosmetic product as defined above. The IRSPS determines the amount of liquid impregnated in the support capable of being released for each of the two faces of the support under the effect of a static pressure and to see if there is a different relaxation between the two faces. The procedure usually adapted by the consumer under the use of the article is to dry the skin or hair with a first side of the article, the other face of the article is in contact with your hand, it is desirable to determine the quantity of liquid released simultaneously by the two faces of the support. For this purpose, a gram of ready gram is weighed accurately, by means of a Mettler Toledo PR5002 balance, two sheets of absorbent material of the dry-type paper, Wypall L30 brand (reference 7303) provided by Kimberley-Clark where the grammage is 50 g / m2. The sheets of absorbent material must be at least large enough that the article to be tested and preferably a little larger in such a way that they exceed the outer edge of the support of at least 2 cm. The first sheet is placed on a glass plate of dimensions at least also large as those of the article to be tested. The item to be tested is placed on the first sheet of Wypall L30. The Wypall L30 sheet is placed on top. The assembly is placed on a metal plate with a surface at least equal to the surface of the article to be tested, weighing 3.7 kg. After one minute the plate is removed and each sheet of Wypall L30 is weighed. The weight of liquid that has impregnated each sheet of Wypall L30 is calculated by different from the mass of Wypall L30 after and before the test. This liquid weight corresponds to the amount of liquid that has been released for each of the two support faces, indicated respectively IRSPS1 for the face having the largest hydrophilicity and IRSPS2 for the face having the lowest hydrophilicity. The ratio between IRSPS1 and IRSPS2 indicates the relaxation difference between the two sides of the canvas. The value retained by the IRSPS1 / IRSPS2 ratio is the average value of measurements carried out in four articles.
Advantageously, the ratio IRSPSl / IRSPS2 is from 1.5 to 15 and preferably from 2.5 to 10 and still preferably from 2.5 to 7. Obviously, when the article is hollow and is configured in particular in the form of a glove, the two sheets are separated that constitute it and the test is carried out on both sheets and separated. THE SUBSTRATE; The substrate is preferably manufactured according to the method of water jet bonding, conventionally used for the preparation of nonwovens. The first stage is the constitution of strata of fibers having different hydrophilicities. These layers can be prepared according to different methods known to those skilled in the art, either by carding from fiber balls, either by extrusion of polymers in the form of continuous filaments of fibers, or by air-pneumatic route. The more hydrophilic fiber substrate as well as the more hydrophilic fiber layer are deposited on a rolling mat and channeled into high pressure water jet ramps that join the fibers together. These jets of high pressure water cause a rearrangement of fibers in three directions to the bosom of the fibrous structure which thus leads to an entanglement of the fibers that link them together without adding chemical bonds. In general, the strata of fibers that pass under several water jet ramps where the pressure gradually increases from the first ramp to the second. This technique is known under the name of hydro-link. The substrate can on the other hand be embossed, stamped, calendered, printed or undergo any kind of treatment at the end of the line. Thus, advantageously, one of the faces of the support, in particular the less hydrophilic, becomes exfoliating, in particular by hot calendering. According to this particular process, it will be noted that, it is formed from two strata of fibers, at the end, the substrate only comprises one layer. The risks of delamination that have been observed in multilayer structures to which reference has been made above are suppressed. The most hydrophilic fibers can be chosen from among cotton, cellulose or viscose fibers. The less hydrophilic fibers can be chosen from polypropylene, polyamide or polyethylene fibers. According to another aspect of the present invention, a single-use cosmetic article comprising at least one substrate of a liquid cosmetic composition is made, the substrate is permeable and comprises at least a first group of fibers and at least one a second group of fibers in which the hydrophilicity is different from that of the fibers of the first group, the first and second group of fibers are arranged in such a way that a first side of the substrate, external to the latter, has a hydrophilicity greater than hydrophilicity of a second face of the substrate, opposite to the first, the article comprises at least a hollow or concave portion, the hollow or concave portion is intended: i) either to receive a surface to be treated in order to put the latter in contact with an internal surface of the article; ii) either receiving all or part of a hand, in view of providing an external surface of the article in engagement with a surface to be treated. Such a hollow or concave article can be configured in the form of a glove, a mitten, a shoe, a finger cot, a cap, a cap or a cariot. Such a hollow article can be obtained by mounting along its respective lower edges of at least "two sheets" or by filling a sheet on itself then by fixing on those same edges of the filled sheet itself. When the hollow or concave portion is intended to receive all or part of a hand, in order to provide an external surface of the article in engagement with a surface to be treated, the more hydrophilic face lies outside of the hollow or concave portion. Advantageously, the substrate is impregnated by the cosmetic composition according to a proportion of 100% to 1000%, preferably 150% and 800% and preferably still 150% and 400% by weight of the composition by weight of non-impregnated substrate . The following examples allow to better understand the invention, without presenting, however, a limiting character. The indicated amounts are in% by weight, unless indicated otherwise. In the following examples, given as illustrative and not limiting, concrete compositions according to the invention are given.
