Description

Soluble cosmetic article

The present invention relates to a cosmetic article comprising a fibrous support capable of dissolving in water, and to a composition containing at least one oil and at least one surfactant. The invention also relates to the uses of this article, especially in cosmetics, more particularly for cleansing and/or removing makeup from the skin and/or the hair.

For removing makeup from or cleansing the skin, it is known practice to use moist wipes consisting of a water- insoluble substrate containing an impregnation composition. The water-insoluble substrate is preferably a nonwoven formed by the entanglement of water-insoluble fibres, of natural or synthetic origin, and this substrate is impregnated with a composition suited to the desired aim, for example for cleansing or removing makeup from the skin or for skincare . These wipes are commonly used and are appreciated for their practical and nomadic aspect since they are disposable and are impregnated with the necessary and sufficient amount of cleansing or treating product.

Among the makeup-removing products commonly used, anhydrous compositions based on mixtures of oils are renowned for their efficacy that is superior to that of aqueous lotions or makeup-removing milks, on account of their high solvent power for makeup compounds. Anhydrous makeup removers allow all types of makeup to be removed and especially waterproof or long- lasting products, which are known to be more difficult to remove than standard products.

Despite their great efficacy, anhydrous makeup removers have a major drawback due to the fact that they leave an unpleasant oily residue on the skin, which is difficult to remove, giving an impression of poorly cleansed skin. One known solution consists in adding to the mixture of oils one or more surfactants allowing an emulsion to be formed by adding water. Thus, after having removed her makeup, the user can rinse her face with water to remove the residual oil film by emulsifying it. This two- stage action allows the skin to be cleansed satisfactorily, by first removing the makeup with the oily composition and then by removing the residual oily film. However, this action is often considered long and tiresome, and has the drawback of requiring the use of a certain amount of water that may, disagreeably, run down the neck and the arms.

Moreover, it is known practice to impregnate compositions based on oils and surfactants into water- insoluble nonwoven supports, as described, for example, in document US-A-6 136 775, in which the wipe is used either directly or premoistened with a small amount of water so as to emulsify the mixture of oils and surfactants. However, irrespective of the composition impregnated, such a wipe is an article which, despite its practical nature, may be a source of discharge by the consumer since it generates waste that may pose a problem during its removal either because there are no waste bins nearby, or because dispersing the soiling present on the article is a nuisance, or quite simply because of the annoyance caused by the fact of generating excess waste.

There is thus still a need for a wipe impregnated with anhydrous makeup remover, and which can be easily removed without any problem and without creating waste after use.

The present patent application satisfies this need. Specifically, the Applicant has found, surprisingly, that it is possible to obtain such a wipe by using a particular wipe support and a specific makeup-removing composition, such that an article is obtained that shows good efficacy and that is easy to remove. Thus, the invention relates to a single-use cosmetic article, more particularly a wipe, comprising:

(1) at least one water-soluble substrate in the form of a nonwoven formed by the entanglement of polyvinyl alcohol fibres, which are soluble in water from a temperature greater than or equal to 35⁰C,

(2) an anhydrous cosmetic composition borne by the support, containing at least one oil chosen from fatty acid esters and liquid petroleum jelly, and mixtures thereof, and at least one nonionic emulsifying surfactant that is soluble in the oil or the mixture of oils, chosen from oxyalkylenated fatty acid esters of sorbitan and oxyalkylenated fatty acid esters of glycerol, and mixtures thereof, the article being substantially dry and being soluble in water from a temperature of greater than or equal to 35⁰C.

In the present patent application, the term "substantially dry article" means an article impregnated with a composition containing less than 15% water, preferably less than 10% water and better still less than 5% by weight of water relative to the total weight of the composition. The composition may also be free of water. The amount of water in the composition may thus range from 0 to 15% by weight, preferably from 0 to 10% by weight and better still from 0 to 5% by weight relative to the total weight of the composition. If the composition contains water, it is generally in the form of a W/0 emulsion, the water being present in the form of droplets dispersed in a continuous oily phase. This small amount of water cannot dissolve the polyvinyl alcohol fibres. According to a preferred embodiment of the invention, the article is free of water.

The expression "article that is soluble in water from a temperature of greater than or equal to 35⁰C" means an article that dissolves by simply placing it in contact with water at at least 35⁰C, i.e. between 35⁰C and 9O⁰C, with the aid of manual agitation and/or friction of the article, where necessary, but which does not dissolve at a temperature lower than 35⁰C.

Moreover, the expression "fibres that are soluble in water from a temperature of greater than or equal to 35⁰C" is understood as fibres that dissolve in water from a temperature of at least 35⁰C, for example at a temperature ranging from 35⁰C to 5O⁰C, with the aid of manual agitation and/or friction of the support, where necessary, within a time of less than 5 minutes, preferably less than 1 minute and preferably less than 30 seconds. The invention does not exclude water with a temperature of greater than 5O⁰C and ranging up to 9O⁰C from being used to dissolve the support.

Patent application FR-2 856 911 describes a single-use article comprising a fibrous support made of water- soluble polyvinyl alcohol fibres, that shrink on contact with water at a temperature of less than or equal to 4O⁰C and that dissolve at a second temperature of greater than or equal to 2O⁰C. The article in question may be impregnated with an essentially anhydrous cosmetic composition, or it may receive this composition after having been premoistened with water at a temperature of less than or equal to 4O⁰C. The compositions mentioned in the said patent application are solids, for instance a powder of a foaming or makeup composition, fatty substances or an encapsulated liquid. No makeup-removing composition is described.

Document JP-09/216 809 describes a support that is soluble in water between 0 and 5O⁰C, containing active agents. The said document does not describe or suggest the impregnation of such a support with a composition that transforms into an emulsion on contact with water, especially with a composition containing the particular oils and surfactants claimed in the present patent application.

The article according to the invention combines a particular substrate and a specific makeup-removing composition that becomes transformed into an oil-in- water emulsion on contact with water, which makes it possible to obtain good makeup removal and better cosmetic comfort.

The article according to the invention may be in the form of a wipe, a cushion, a compress, a pad or any other form that is suitable for removing makeup from the face and the eyes .

In one example of implementation of the invention, the article according to the invention is used in the following manner:

(1) the article impregnated with the anhydrous composition is passed over the skin, (2) the article is then moistened with cold water

(running tap water, which generally has a temperature of 18⁰C to 2O⁰C) to remove both the excess remaining anhydrous composition present on the article and the makeup products deposited on the article during step (1) ,

(3) the moist article is again passed over the face, which allows the anhydrous composition on the skin to be emulsified and thus allows the residual oily film and any remaining makeup to be removed, and also to perfect the makeup removal and the cleansing of the skin,

(4) the article is then dissolved in warm water (at least 35⁰C) .

Step (3) may optionally be repeated, if necessary.

Thus, according to another of its aspects, a subject of the invention is also a cosmetic process for cleansing or removing makeup from the skin, which comprises: - placing an article as defined above in contact with the surface of the skin,

- moistening the article with cold water,

- placing the moistened article in contact with the skin,

- dissolving the article in water at a temperature of at least 35⁰C.

In another implementation variant of the invention, the skin is premoistened and the article according to the invention is placed in contact with the premoistened skin.

Since the article according to the invention is intended for topical application, it is physiologically acceptable. The term "physiologically acceptable" refers to an article that is compatible with keratin materials such as the skin, the lips, the nails, the scalp and/or the hair. This is likewise the case for the substrate, and also for the composition.

The article is flexible, i.e. supple. The term "supple" should be understood as meaning an article that can be compressed or flexed without breaking, capable of adapting to the reliefs of the human body. A supple article made in the form of a fibrous web may in certain embodiments be folded on itself at least once without breaking into two pieces.

After its manufacture, the article may be packaged, for example, in bulk in a box or in individual wrapping. Where appropriate, the articles are packaged in string form. The articles may also be folded on themselves and intercalated, such that the removal of one article entrains the next in a configuration that makes it easy to be taken out .

Thus, according to another of its aspects, a subject of the invention is also an assembly comprising: - wrapping ,

- at least one article as defined above.

Substrate To make the nonwoven substrate, polyvinyl alcohol fibres that are soluble in water at a temperature of greater than or equal to 35⁰C are used, for instance the fibres sold by Kuraray under the name Kuralon K-II, and particularly the grade WN4 that is soluble at and above 4O⁰C or WN5 that is soluble at 5O⁰C. These fibres are described in document EP-A-636 716, which teaches the manufacture of polyvinyl alcohol (PVA) fibres that are soluble in water at temperatures not exceeding 100⁰C, by spinning and drawing the polyvinyl alcohol polymer in wet or dry form in the presence of solvents involved in the dissolution and solidification of the fibre. The fibre thus obtained can lead to the preparation of woven or nonwoven substrates. Document EP-A-636 716 also teaches that the solubility temperature of the fibre depends on the proportion within the polymer between the polyvinyl alcohol groups and the polyvinyl acetate groups, i.e. it depends on the degree of saponification of the vinyl acetate groups. It may thus be envisaged to modify the solubility temperature of the fibre and thus of the article, in order to target a dissolution temperature of the article that is neither too low nor too high, while at the same time allowing the use of the techniques that are the most suitable for the manufacture of the nonwoven support. For example, the fibres may be formed by extrusion and deposited on a conveyor to form a web of fibres that is then consolidated via a standard fibre bonding technique, for instance needle-bonding, hot-bonding, calendering or bonding via jets of hot air (air-through bonding), in which technique the web passes through a tunnel where hot air is blown through it, or hydrobonding aimed at bonding the fibres via the action of fine jets of water at very high pressure, which cannot be applied to fibres whose dissolution temperature is too low.

The invention is not limited to the use of PVA alone, and fibres made with a mixture of PVA and of other water-soluble materials may also be used, provided that these materials dissolve in water having the desired temperature, for example polysaccharide fibres or fibres made of polyholoside polymers, for instance glucomannan or starch.

The fibres used in the present invention may be more or less long, the length possibly ranging, for example, from 30 to 75 mm. They may also have a yarn count ranging, for example, from 1.5 to 3 dtex and preferably from 1.7 to 2.5 dtex, the dtex being the weight in grams of 10 000 m of yarn.

The substrate may have any shape that is suitable for the intended use, for example a rectangular, circular or oval shape, and it preferably has dimensions that allow it to be taken up between at least two fingers. Thus, the support may have, for example, an ovoid shape of about 2 to 10 cm long and about 0.5 to 4 cm wide, or a disc shape of about 2 to 10 cm in diameter, or a square shape with a side length of about 5 to 15 cm, or a rectangular shape with a length of about 5 to 25 cm, it being understood that it may have any other form and dimensions suitable for the intended use.

The article according to the present invention may comprise one or more nonwoven substrates that are soluble in water at a temperature of greater than or equal to 35⁰C.

When the support comprises several nonwoven webs, they may be assembled especially by hot-bonding at their periphery. Oi l s

The composition contains one or more oils, chosen from fatty acid esters and liquid petroleum jelly, and mixtures thereof. It may also contain one or more oils other than those mentioned above. The total amount of oils is preferably of at least 50% by weight relative to the total weight of the composition. The total amount of oil(s) may range, for example, from 50% to 99.5% by weight, preferably from 60% to 98% by weight and better still from 70% to 95% by weight relative to the total weight of the composition.
