Description

COSMETIC COMPOSITION FOR NAILS

TECHNICAL FIELD [0001] The present invention relates to a cosmetic composition that can be applied either directly to the nails or false nails, or to nails or false nails previously made up with a colored or transparent varnish called base coat.

State of the art [0002] Nail polishes are generally used for makeup nails as well as false nails. The vast majority of nail polishes sold on the market have as their main constituent volatile organic solvents. These same compositions also comprise film-forming agents, resins, one or more rheology agents as well as coloring agents that are compatible with volatile organic solvents used, such as, for example, ethyl acetate or butyl acetate.

In general, to meet the requirements of consumers, nail polish must meet several criteria: • A good application. The varnish must form a homogeneous and smooth surface, without streaks and without bubbles. • Optimal spreading over the entire surface of the nail. • Increased brilliance that holds in time. • A relatively short drying time. • Good durability with minimal flaking and minimal wear at the end of the nails.

In order to meet these requirements, and in particular to improve these different properties, new formulations or typologies of formulas are developed.

In addition to meeting all the characteristics mentioned above, users constantly claim nail polish with new aesthetic effects. Nail polish has become a fashion accessory and must adapt to changing trends.

The varnishes must therefore adapt to color trends by the implementation of specific dyes but they must also adapt to trends that are more related to its surface finish. The last few years have seen the commercialization of nail polish with mirror effect, metallic or matte. Thus the application US201220294918 describes a varnish with a particular touch described as "velvety feel". EP2420222 discloses a composition having a velvet feel. There are also requests for effects with non-homogeneous surfaces. Thus, EP2819642 discloses a patterned nail polish composition, EP1040813 discloses a hammered nail composition and US20120308497 describes a crackle nail polish.

OBJECT OF THE INVENTION [0007] An object of the present invention is therefore to find nail polish compositions that make it possible to obtain an original aesthetic effect that is likely to please consumers.

General Description of the Invention [0008] In order to solve the above-mentioned problem, the present invention provides, in a first aspect, an aqueous cosmetic composition which comprises one or more solvents (water as the main solvent and optionally a or several water-miscible co-solvents), one or more film-forming agents, one or more preservatives, one or more surfactants or surfactants and one or more fluorinated organic compounds (organofluorines).

In a second aspect, the invention relates to the use of an aqueous cosmetic composition according to the invention to obtain an aesthetic effect said effect "lace" comprising random patterns after drying. The aesthetic effect of these random patterns could also be designated "crater" effect or "bubble" effect without limitation to these names or type of visual effect.

A third aspect of the invention relates to a method for preparing aqueous cosmetic compositions according to the invention for the makeup of nails.

It should be noted that in the context of the present invention the term "nail" refers to both natural nails and false nails.

The particular nature of the composition according to the invention which can be applied in the form of a foam requires the use of ingredients dedicated to the introduction of air within the formula. The use of surfactants (or surfactants) facilitates the formation of a foam following agitation and the temporary stabilization thereof. However, the application on the nails being done conventionally with a brush, the bubbles of the foam can be destroyed during the application and the particular effect would be lost. Thanks to the introduction of organofluorinated compounds, the foamed composition can be stabilized during at least the time of the realization of the manicure or make-up of nails previously made or not makeup.

A particular advantage of aqueous cosmetic compositions for nails according to the invention is that they can be removed with water if they have not "fixed" by a protective layer or top coat. Thus, the compositions according to the invention can be used without top coat to test the compositions or for short-term uses. In addition, if the random pattern obtained during the application does not like, it is very easy to start again.

The aqueous cosmetic compositions according to the invention may be covered with a varnish composition comprising one or more organic solvents called top coat in order to protect it and thus provide a better behavior in time of the effect obtained.

The main solvent of the composition according to the invention is water. The amount of water present in the formula is generally from 20% to 70% by weight, preferably from 25% to 60% by weight.

The composition according to the invention may also contain one or more co-solvents for modulating the drying times and facilitate the formation of the film by a phenomenon of coalescence. Co-solvents also make it possible to improve the dispersion or the solubilization of certain ingredients of the present invention.

These cosolvents are soluble ingredients in the main solvent. Among the cosolvents that can be used in the present invention, mention will in particular be made of: • Ethanol • Isopropyl alcohol • Propylene glycol • Butylene glycol • Or propylene glycol n-butyl ether [0017] Co-solvents can be present in the composition according to the invention in amounts of 0.5% to 15% by weight, preferably 1% to 10% by weight of the composition.

If necessary or desired, the compositions according to the present invention may also comprise one or more plasticizers in order to modulate the hardness of the formed film. These are generally soluble compounds or compatible with the main solvent and any co-solvents. Plasticizers generally have high boiling temperatures. They are not volatile. Among the plasticizers that can be used in the context of the present invention, mention may be made of: • glycerin • acetyl tributyl citrate • acetyl triethyl citrate • tributyl citrate • triethyl citrate [0019] If the composition comprises one or more plasticizers, the amount to be used is generally of the order of 1% to 10% by weight of the composition and preferably between 1% and 5% by weight of the composition.

The composition according to the invention contains a film-forming agent or polymer which, as its name indicates, has the ability to form a film after drying. These film-forming agents are in the form of aqueous emulsions or dispersions. These film-forming polymers are compatible with the main solvent and co-solvents and with the possible plasticizers.
