ANHYDROUS COSMETIC COMPOSITION APPLICABLE ON NAILS

TECHNICAL FIELD [0001] The present invention relates to nail polishes comprising a novel film-forming agent and which are at least partially biosourced.

STATE OF THE ART [0002] The current nitrocellulose film-forming agents have two major defects in formulation, namely their opacity and their tendency to yellow more or less rapidly over time. It is important to note also that they have a certain instability that can make them flammable or explosive, which complicates the conditions of storage and handling.

Despite attempts have already been made to substitute this product, it continues to be the base resin widely used in all nail polish formulations.

[0004] There is therefore a need to substitute nitrocellulose with other more stable and compatible materials in nail polish formulations. On the other hand, this material must always make it possible to obtain the different properties that are required, today, to a nail polish, namely: - a good application, when the nail polish is applied to the nail, it must form a smooth, streak-free surface with a constant thickness in order to obtain a homogeneous film and coloring, - easy spreading over the entire surface of the nail to make its practical use, - increased gloss and which persists in the time, - a drying time and hardening on the nail very short, and - a good performance of the nail polish on the nail, it is indeed desired that the varnish flakes as little as possible to maintain a aesthetic appearance.

In general, in the field of nail polish, there is a constant demand for new products with improved properties, especially in terms of ease of application, speed of drying, durability, aesthetics, etc. Increasingly, there is also a growing awareness of users for more environmentally friendly products.

OBJECT OF THE INVENTION [0006] An object of the present invention is therefore to propose novel nail polish compositions which comprise a new film-forming agent which can overcome the drawbacks mentioned above, preferably without having to use nitrocellulose, but preferably without altering (significantly) the other important properties of the nail polish, including strength, gloss, coverage, drying time or hardening.

General description of the invention [0007] In order to solve the problem mentioned above, the present invention provides an anhydrous composition for nail polish comprising at least one cosmetically acceptable organic solvent and at least one biopolyester-type film-forming agent, the biopolyester. being polylactic acid and the cosmetic composition not containing nitrocellulose. In a preferred variant, the amount of polylactic acid is between 0.1% and 45% by dry weight relative to the total weight of the composition and even more preferably between 1% and 25% by weight, particularly preferably preferred between 5% and 12% by dry weight relative to the total weight of the anhydrous composition.

[0008] Surprisingly, it has been demonstrated that polylactic acid, which is a biocompatible biosourced polymer, offers a very interesting and quite innovative alternative to nitrocellulose.

The polylactic acid can be obtained in particular from corn starch. Indeed, polylactic acid is a product resulting from the fermentation of sugars or starch under the effect of bacteria synthesizing lactic acid. In a second step, the lactic acid is polymerized either by a new fermentation process, or chemically to become polylactic acid. He belongs to the family of biopolyesters. Thus, the use of polylactic acid leads to the production of an anhydrous nail varnish composition which offers good application, has a good hold, gloss, coverage and drying and curing time. . The polylactic acid used is preferably that marketed under the following names: Ingeo Biopolymer 10361 D (low molecular weight) and Ingeo Biopolymer 4060 D (higher molecular weight).

Polylactic acid can be used in all types of anhydrous compositions for conventional nail polish and as for example effect nail polish (mirror, cracked, iridescent, hammered, magnetic, matte, metallized etc.) , long-lasting nail polish ("gel like"), but also nail polish called "top coat" or "base coat" (intended to be applied on or below a nail polish).

The anhydrous composition for nail polish comprises an organic solvent. The organic solvent may be selected according to its physico-chemical properties and in consideration of the other components present in the anhydrous composition for nail polish.

This organic solvent may be chosen from the group consisting of toluene, xylene, methyl acetate, ethyl acetate, butyl acetate, isobutyl acetate, ethyl acetate and the like. propyl, a ketone, an ester, an alcohol, such as denatured ethanol (with methyl ethyl ketone or diethyl ether), isopropanol, butanol, diacetone alcohol, linear or cyclic hydrocarbons, such as, for example, hexane, cyclohexane, heptane and any combination thereof.

Preferably, the amount of organic solvent present in the anhydrous composition for nail polish is generally between 60% and 80% by weight relative to the total weight of the composition.

[0014] Advantageously, the organic solvent is ethyl acetate and / or butyl acetate and / or an alcohol; or one of their mixtures.

If necessary or desired, the composition may also comprise one or more other film-forming agent (s) alone or a combination, preferably in a much smaller quantity than in the absence of polylactic acid. The percentage of the other film-forming agent (s) in the formula may range from 0.5% to 15% by dry weight and preferably from 2% to 5% by dry weight. relative to the total weight of the composition.

The other film-forming agent (s) optionally included in the nail polish composition may be selected from the group consisting of cellulose, a cellulose derivative, a vinyl resin, an acrylic resin and any combination thereof. The cellulose derivatives are, for example, butyrate acetate cellulose, ethylcellulose and hydroxypropylcellulose. Preferentially, acetate butyrate cellulose will be chosen as film-forming agent. In general, the anhydrous nail polish compositions of the invention do not contain nitrocellulose at all.

The composition according to the invention may also contain conventional resins. Conventional resins that can be used are as follows: • Polyester resins • Epoxytosylamide resins • Acrylate and styrene-acrylate resin • Sucrose perbenzoate [0018] Additional resins can also be added to the composition. In particular, these additional resins make it possible to increase the tackiness and the adhesion of the film to the nail.

The additional resins that can be used are as follows: • tosylamide / formaldehyde resins or toluenesulfonamide / formal-d-hyde resins, • tosylamide / epoxy resins or toluenesulfonamide / epoxy resins, • adipic acid copolymer resin , fumaric acid, neopentyl glycol and cyclohexanedimethanol • Copolymers adipic acid / neopentyl glycol / trimellitic anhydride • Copolymers of phthalic anhydride / glycerin / glycidyl decanoate • Copolymers of phthalic anhydride / trimellitic anhydride / glycols • Copolymers of glycerine / phthalic acid, • Styrene / acrylate / acrylonitrile copolymers, • Polymers and copolymers of acrylates, • Copolymers of acrylates and styrene, • Sucrose acetate isobutyrate, • Polyvinylbutyral resin.

In addition to their sticky action, most of these resins also have a plasticizing action. The resins can be used in the formula, alone or in the form of mixtures, in amounts ranging from 1% to 25% by dry weight, preferably 5% to 15% by dry weight, in particular from 7% to 12% by weight. in dry weight relative to the total weight of the composition.

The composition according to the invention may also contain plasticizers. Plasticizers are compounds with a high boiling point that do not evaporate when the nail polish dries. These ingredients are preferably used to modulate the hardness of the formula. These plasticizers are generally non-volatile compounds and compatible with the media in which they are added. They generally represent from 1% to 12% by dry weight, preferably from 5% to 10% by dry weight, in particular from 6% to 8% by dry weight relative to the total weight of the composition.

Examples of plasticisers used in the invention are acetyl tributyl citrate, acetyl triethyl citrate, tributyl citrate, triethyl citrate, dibutyl phthalate, triphenyl phosphate, triacetin, trimethyl pentanyl diisobutyrate, triethyl hexanoïne , sucrose benzoate, dibutyl adipate, diethyl phthalate, diisobutyl adipate, diisopropyl adipate, dipropylene glycol dibenzoate, N-ethyl toluene sulfonamide, its ortho and para isomers, N- (2-hydroxypropyl) benzene sulfonamide and N- (n-butyl) benzene sulfonamide, etc.

According to one embodiment of the invention, the anhydrous composition for nail polish comprises an amount of coloring agent of from 0.1% to 20% by dry weight and preferably from 0.5% to 12% by weight. % by dry weight relative to the total weight of the composition.

All the embodiments mentioned above can be combined subject to their technical feasibility.

Example [0037] Below in Table 1, an example of a formulation according to the invention. The effect of polylactic acid on the gloss, hardness, adhesion, viscosity, thixotropy and hardening of nail polish is shown in Table 2 in comparison to a conventional nitrocellulose nail polish.

Table 1

In order to determine the gloss of the film formed, the glossmeter analysis is carried out on dry films applied to standardized contrast cards using an applicator allowing the formation of a wet film with a thickness of 100 pm. The deposited film is dried at 30 ° C. for 12 hours. The gloss is measured at an angle of 60 relative to the normal of the film and is carried out three times. The final value obtained is the average of these three measurements.

Regarding the measurement of thixotropy, three different measurements are made corresponding to the different stresses experienced by the varnish during the application. A first measurement is made for the varnish at rest, the spindle of the viscometer rotates at a speed of 6 rpm for one minute. It then goes to 60 rpm to model the mixture in the bottle and then the nail application. Finally, the speed of rotation returns to 6 rpm to model the behavior of the varnish once spread on nail and therefore at rest. The ratio between the third viscosity and the second gives the thixotropic index.

The hardness of the base is controlled by spreading a thin film of 100 .mu.m on a glass plate using a barcoater. The plate is put in the oven for 12 hours. Hardness is measured with a Persoz pendulum. The pendulum hardness test is based on the principle that the amplitude of oscillation of a pendulum which touches a surface decreases more rapidly if this surface is soft. The glass plate is locked between the pendulum support and a metal plate. The hardness is noted in number of oscillations of the pendulum before reaching an angle of 4 °.

The adhesion is tested with a knife with four parallel blades. The plate where the base was laid is scratched vertically and horizontally so as to draw small squares. It is by observing the detachment of the parts of the base that one qualifies the adhesion of this one.

[0043] Table 2

It is found that the properties of the nail polish composition comprising polylactic acid are identical or very similar to the properties of a composition for conventional nail polish comprising nitrocellulose.

This confirms that polylactic acid represents a completely innovative alternative to nitrocellulose.
