Description

Aqueous composition based on alcohols, surfactants and solubilizers, articles immersed in such compositions and methods for washing hair.

The present invention relates to a hair composition for washing hair and to said composition comprising at least one C ₂ -C ₄ monoalcohol, at least one surfactant and at least one fat soluble compound solubilizing agent in a cosmetically acceptable medium. It relates to a hair washing method used.

Hair tends to lose some of its properties under the action of factors such as natural oils, sweat, scaly removal, contamination, humidity, and the like. These factors are detrimental to the appearance and feel of the hair. Thus, re-oiling (and possibly contamination) tends to crush the hair and entangle each other. Therefore, the hair is difficult to form, has an unpleasant oily gloss, and becomes lustrous and unpleasant in texture.

The degree of consequences from these factors varies (almost all can not be avoided). This depends, for example, on the nature of the hair, its length and the hairstyle adopted.

In any case, shampoos are used to eliminate this inconvenience. Indeed, washing with detergent compositions is very effective; This makes it possible to remove dust and dandruff. While drying, it is then possible to restore the hair to the desired shape. However, the beneficial effect of the shampoo disappears in a few days, and the problem described above recurs. As a result, this results in a tendency to increase the frequency of shampooing.

In shampooing the hair, it is necessary to use water, preferably hot or warm water.

Shampoo compositions are based on large amounts of surfactants that cause discomfort such as irritation to the scalp or eyes.

It is already proposed to use "gun" shampoos to wash the hair more quickly and to avoid wetness of the hair. This technique consists in spraying the absorbent particles onto the hair and then actively combing the hair to remove the particles. However, in general, complete removal of the particles is very difficult. The results are not very satisfactory. The hair is not very shiny and rough in texture.

It is an object of the present invention, in particular, to solve the above problems.

More precisely, the present invention proposes a method for washing hair, which aims to give the hair a neutral feel and a neutral appearance after use, as a result.

At present, unexpectedly and surprisingly, it has now been found by the applicant that the object can be achieved by using a liquid cosmetic composition, in particular a composition for hair for hair washing, as a result of considerable research carried out on the subject, The composition is contained in a cosmetically acceptable aqueous medium.

10 to 90% by weight of at least one C ₂ -C ₄ monoalcohol, based on the total weight of the composition,

0.01 to 5% by weight, based on the total weight of the composition, at least one surfactant selected from anionic surfactants, amphoteric and / or zwitterionic surfactants and nonionic surfactants,

0.01 to 5% by weight of a solvent of a fat-soluble compound selected from linear or branched hydrocarbons, hydrogenated or non-hydrogenated polyolefins, volatile silicones and mixtures thereof,

It contains 1 to 89.98% by weight of water.

The hair washed with the composition according to the present invention has the characteristics of clean hair: it has a natural feel, the hair is shiny (oily appearance is extinguished), and the hair is brittle, light, and dandruff disappears. In addition, the hair is better adjusted, more resilient and smoother. The treatment also removes unpleasant odors.

The object of the present invention is therefore also the cosmetic use of the cosmetic composition as defined above for washing the hair.

The object of the present invention is also in a method for washing hair, which method is characterized in that the composition defined above is applied to dry hair, which is then characterized in that the hair is in a dry state.

The composition according to the invention is prepared according to techniques well known to those skilled in the art.

The composition can be applied to hands, tips of applicators, sprayers, dispensing combs and preferably insoluble substrates on which the composition is immersed.

Applicants have found that the use of insoluble substrates for applying the compositions has particularly advantageous results.

Thus, according to a preferred embodiment of the present invention, the composition according to the present invention can also be used to immerse with the insoluble substrate to make articles, in particular hair wash towels or gloves. The insoluble substrate may comprise one or more layers, which may be selected from the group consisting of wovens, nonwovens, foams, sponges or cotton wool, sheets, balls or films. It is especially based on natural fibers (flax, wool, cotton, silk) or synthetic fibers (cellulose derivatives, viscose, polyvinyl derivatives, polyesters such as polyethylene terephthalate, polyolefins such as polyethylene or polypropylene, polyamides such as nylon, acrylic derivatives) It may be a nonwoven substrate. Such nonwovens are generally described in Riedel "Nonwoving Bonding Methods & Materials", Nonwoven World (1987). Such substrates can be obtained according to the general methods of nonwoven fabric manufacturing techniques.

When the substrate is a nonwoven fabric, a thick nonwoven fabric may be used that does not curl into a ball shape, is hard enough not to degrade, and does not penetrate into the skin when applied. It will be absorbent and soft, at least on one side, especially in removing makeup from the eyes. Suitable nonwovens are sold, for example, under the names Vilmed M1519 Blau, Vilmed M 1550 N and 112-132-3 by Ultraloft 15285-01, Ultraloft 182-008, Ultraloft 182-010 and Ultraloft 182-016 and Freudenberg by BBA Refers to those sold under the name Norafin 11601-010B by Jacob Holm Industries, under the name Aquadim VE50 G1NL (string) from Tharreau, and the flocked nonwovens under the name Univel 119 by Uni Flockage. can do.

In addition, such substrates may include one or more layers having the same or different properties, and may have properties suitable for resilience and softness, and other desired applications. The substrate may contain, for example, two constituents with different resiliency as described in the [WO-A-99 / 13861] document, or as described in the [WO-A-99 / 25318] document, It may comprise a single layer with different densities, or may comprise two layers of different textures as described in [WO-A-98 / 18441].

The article preferably constitutes gloves, but can also be in other forms (eg, towels).

Accordingly, an object of the present invention is also an article containing an insoluble substrate and a composition immersed with the substrate, as defined above.

The object of the present invention is also the use of the composition as defined above for the manufacture of articles for washing hair.

According to another aspect of the invention, the one-time cosmetic article contains at least one substrate immersed in the liquid cosmetic composition as defined above, wherein the substrate is permeable and consists of at least one group of fibers and at least one group of fibers 2 , The hydrophilicity of the second group is different from the hydrophilicity of the fiber of the first group, the first and second groups of the fiber is more hydrophilic than the hydrophilicity of the two sides of the substrate, one side of the substrate is opposite to the one side Arranged so as to be visible, the first side is made to be in contact with the surface to be treated, in particular the hair.

In the article, the income on the cosmetic treatment effect can be increased by making the amount of the composition immersed in the article to be liberated on the surface to be treated.

The term "permeable" refers to a substrate of full thickness through which the cosmetic composition can pass. Thus, unlike some of the articles of the prior art provided above by reference, the articles according to the invention do not comprise an impermeable layer which can impede the composition immersed therein.

Of course, the substrate is insoluble, such as its integrity is not substantially affected by the presence of the aqueous cosmetic composition immersed therein, at least over the lifetime of the product.

Advantageously, the substrate is a monolayer substrate. The term "monolayer substrate" refers to a substrate in which all the fibers constituting it are interconnected during the same connection process. As a result, in the thickness of the substrate, the distribution of the two types of fibers is non-uniform, and according to one profile:

Most of the fibers of Group 1 on one side of the substrate;

Most of the two groups of fibers on two sides of the substrate, and between the two sides,

Can be characterized by the inclination of the opposite sign relative to that of the relative progression profile corresponding to the relative amounts of the Group 1 fibers, the relative amounts of the fibers of the 2 groups that vary according to the relative progression profile.

The structure differs from a multilayer structure in which various layers are formed and bonded separately, followed by thermal bonding, hot welding or ultrasonic waves.

Advantageously, one side of the substrate has one under static release index (RISP1), the back side of the substrate has one under static release index (RISP2) and the RISP1 / RISP2 ratio is at least 1.5.

RISP (static pressure release index):

The static release index (RISP) of the two sides of the article immersed with the cosmetic product described above can be measured through the test described below. The RISP determines the amount of liquid immersed in the support that can be separated from each of the two sides of the support under static pressure, indicating whether there is a difference in discharge between the two sides.

Gestures, which are mainly adopted by the consumer during the use of the article, wipe their skin or hair with one side of the product, and the other side of the article consists of being in contact with the hand, thus simultaneously releasing from both sides of the support It is desirable to determine the amount of liquid to be.

For this purpose, two sheets of absorbent material of paper towel type having a basis weight of 50 g / m ² , under the trade name Wypall L30 (ref. 7303) sold by Kimberley-Clark, were prepared using a Mettler Toledo PR5002 balance. Weigh accurately to 1 gram. The sheet of absorbent material should be at least as large as the article to be tested, and preferably slightly larger to cover at least 2 centimeters of the outer edge of the support.

The first sheet is placed on a glass plate having at least as much area as the article to be tested. The article to be tested is placed on the first sheet of Wypall L30. The second sheet of Wypall L30 is placed on top of it.

A metal plate weighing 3.7 kg weighing at least a surface area of the article to be tested is placed on the assembly. After 1 minute, the plates are removed and each Wypall L30 sheet is weighed.

The weight of the liquid immersed in each Wypall L30 sheet is calculated as the mass difference of Wypall L30 before and after the test. The weight of the liquid corresponds to the amount of liquid released from each of the two sides of the support, known as RISP1 for the side with higher hydrophilicity and RISP2 for the side with lower hydrophilicity, respectively.

The ratio between the RISP1 and RISP2 represents the emission difference between two sides of the towel.

The value maintained at the RISP1 / RISP2 ratio is the average value of the measurements determined for the four articles.

Advantageously, the RISP1 / RISP2 ratio is in the range of 1.5 to 15, preferably 2.5 to 10, more preferably 2.5 to 7.

Clearly, when the article is hollow and in particular in the form of a glove, the two sheets that make up it are separated and a test is performed on the separated sheets.

temperament:

The substrate is preferably prepared according to the water-jet bonding process commonly used for the production of nonwovens.

The first step is to prepare a knit of fibers having different hydrophilicity. Such knits can be prepared by carding with fiber bundles or extruding polymers in the form of continuous filaments of fibers, or by pneumatic paths, according to various methods known to those skilled in the art.

The knit of the most hydrophilic fibers and the knit of the least hydrophilic fibers are placed on a conveyor belt and transported under a series of very high pressure water, where the fibers are joined together. This ultra high pressure causes rearrangement of the fibers in three directions within the fiber structure, thus causing overlap of the fibers and allowing them to bond together without the addition of chemical binders. Generally, the knit fabric passes under several rows of ultra high pressure water, with increasing pressure from the first row to the end. This technique is known as hydrobonding.

The substrate may also be embossed, hemstitched, calendered or some type of line-end treatment. Thus, advantageously one of the surfaces of the support, in particular the surface having minimal hydrophilicity, is in particular exfoliated by hot-gloss.

According to this particular method of manufacture, it should be noted that although formed from two knit fabrics, the substrate eventually consists of only a single layer. The risk of delamination that can be observed in the multilayer structure provided by reference above is eliminated.

The most hydrophilic fibers can be selected from cotton, cellulose or viscose fibers.

Fibers with minimal hydrophilicity can be selected from polypropylene, polyester, polyamide or polyethylene fibers.

According to another aspect of the present invention, a one-time cosmetic article contains at least one substrate immersed in a liquid cosmetic composition, wherein the substrate is permeable and consists of at least one group of fibers and at least one group of fibers. The hydrophilicity of group 2 differs from the hydrophilicity of the group 1 fibers, wherein the fibers of group 1 and group 2 have one side of the substrate (outside the substrate) than the hydrophilicity of the two sides of the substrate (opposite to the side 1). Arranged to show greater hydrophilicity, the article comprises one or more hollow or concave portions, wherein the hollow or concave portions are:

Iii) receive a surface to be treated such that the surface is in contact with the inner surface of the article;

Ii) or to receive all or part of a hand so that the outer surface of the article is used as a treatment surface.

The hollow or concave article may be in the form of finger gloves, mittens, slippers, finger wraps, bonnets, skull caps or head caps.

The hollow article can be obtained by joining at least "two sheets" along their respective corners or folding one sheet on itself, and then fixing the corners of the folded sheet.

If the hollow or concave portion receives all or a portion of the hand so that the outer surface of the article is used as a treatment surface, the most hydrophilic side is outside of the hollow or concave portion.

Advantageously, the substrate is in the range of 100 wt% to 1000 wt%, preferably 150 wt% to 800 wt%, more preferably 150 wt% to 400 wt%, based on the weight of the composition relative to the weight of the unimmersed substrate. Depending on the degree, it is immersed in the cosmetic composition.

The following examples will make the invention more fully understood, without any limitation in nature. The amounts indicated are in weight percent unless otherwise noted.
