ABSTRACT:
The present invention relates to a cosmetic composition comprising an antiperspirant which can be used for making up the skin, semi-mucous membranes, mucous membranes and/or superficial body growths. The antiperspirant composition can be in the form of an emulsion, a gel or a vesicle dispersion.
Cosmetic compositions, in particular make-up compositions such as lipsticks, concealers or foundations, generally comprise fatty substances such as oils and waxes, and a particulate phase generally composed of fillers and pigments. They can thus be, for example in the case of lipsticks, in the form of a stick or tube or in the form of a soft paste. They are then often in the form of an anhydrous composition. Make-up compositions can also comprise water or a hydrophilic phase, and can then in particular be in the form of an oil-in-water or water-in-oil emulsion, a multiple emulsion or an aqueous solution or gel, in particular when it is a foundation, a tinted cream, a care cream or an antisun product.
The primary function of these compositions, which are first and foremost make-up products, is to beautify the human form by emphasizing, for example, the aesthetic qualities and/or by dissimulating facial imperfections.
Depending on the make-up effect which it is desired to obtain, light, discrete or, on the contrary, accentuated, the face is sometimes given a shade close to an individual's natural carnation color, and sometimes a stronger color which heightens the natural complexion: foundations are used for this. Certain reliefs can also be accentuated by providing stronger tones, for example using blushers. Sharper tones which cover all color shades are used to heighten the look. Lastly, the lips are made to stand out by giving them generally dark colors.
In all cases, the result is obtained by virtue of the presence of pigments and/or dyes in these various compositions, each of which has a quite specific function. Thus, the nature of the pigments, their color and, especially, their proportion in each of these compositions are important for obtaining the desired shade and thus the desired effect.
It is thus also important for the distribution of these pigments and/or dyes to remain constant and uniform over time, i.e. several hours after application. In order to maintain an aesthetic overall make-up effect on the face, it is of prime importance that the colors imparted by each of the compositions (foundation, blusher, eyeshadow, lipstick, etc.) at the time of their application do not become mixed.
However, it is quite often the case that the overall make-up effect deteriorates shortly after the products are applied: specifically, it has been found that certain compositions have a tendency to travel inside the wrinkles and/or fine lines in the skin, in the case of foundations; in the fine lines around the lips, in the case of lipsticks; in the folds of the eyelids, in the case of eyeshadows. The appearance of lines in the make-up, generated by the movements of the eyelids, has also been found, especially in the case of eyeshadows. The appearance of lustrous or shiny parts or alternatively the dilution of the covering power and the color can also be observed. This can be due to a multitude of factors such as, for example, heat or humidity. In particular, the distribution of the colors is no longer as uniform. Shiny parts and darkened parts can thus appear on the made-up face, and are contrary to the desired aesthetic effect.
Women nowadays desire make-up products which give them a fresh complexion and a healthy appearance throughout the day while at the same time being practical to use. Thus, they do not wish to reapply their products several times a day in order to have a permanently sharp make-up effect.
It would also be advantageous to have available a single product which could be used in summer and winter, and in hot and cold countries. Such a universal product would be very practical for women who travel, since it would save time and be less expensive.
A need thus exists for a cosmetic composition, in particular a make-up composition, which not only has good cosmetic properties but also gives the skin a coloration whose distribution remains uniform and constant over time and after application to the skin, in particular to the face.
The inventors have now discovered, surprisingly, that by introducing an antiperspirant into compositions comprising pigments, it is possible to prepare make-up compositions whose color distribution can be constant over time, in particular after application to human skin.
A subject of the invention is thus a cosmetic composition, in particular a make-up composition, comprising a pulverulent phase in an amount of less than or equal to 80% by weight, relative to the total weight of the composition. This pulverulent phase includes at least one pigment and also comprises at least one antiperspirant.
In the article “Preventing Makeup Darkening During Usage”, Akira Matsueda and Tsuyoshi Ogihara, Cosmetics & Toiletries, Vol. 111, November 1996, it is taught that the secretion of sebum causes darkening of make-up products. To overcome this drawback, it is proposed to introduce a porous silica comprising a white pigment into the compositions. However, the article does not propose introducing an antiperspirant into a make-up product, in particular a product for the face, in order especially to improve the staying power of the color after application over time and to reduce the sheen of the make-up effect.
The compositions according to the invention can give the face a particularly stable coloration whose distribution can remain uniform over time, even several hours after application.
Furthermore, these compositions can have excellent staying power: preferably, they do not migrate in folds such as the eyelids or fine lines and preferably, no accumulation of product in certain areas of the face is observed. They can also show very little transfer onto supports such as glasses or clothing. They can give the skin a uniform make-up effect and a good matt effect. They can avoid making the face look sticky and can keep the face rather dry, which is particularly desired in hot and humid climates.
A subject of the invention is also the use of an antiperspirant in a cosmetic composition, in particular a make-up composition comprising at least one pigment, in order to limit, reduce or prevent the transfer and/or migration of the composition.
A subject of the invention is also the use of an antiperspirant in a cosmetic composition, in particular a make-up composition comprising at least one pigment, in order to limit, reduce or prevent the composition from transferring and/or migrating on the skin.
A subject of the invention is also the use of an antiperspirant in a cosmetic composition, in particular a make-up composition to be applied to the skin and/or mucous membranes and/or the scalp, this composition comprising at least one pigment, in order to reduce the amount of water present on the skin and/or mucous membranes and/or the scalp.
The compositions according to the invention find a particularly advantageous application especially in making up the skin, mucous membranes, semi-mucous membranes and superficial body growths. The expression “mucous membranes” especially means the inner part of the lower eyelid; the expression “semi-mucous membranes” more particularly means the lips of the face; the expression “superficial body growths” means the eyelashes, eyebrows, hair and nails. Thus, the invention can be used for make-up products for the face and the skin, such as foundations, self-tanning products or antisun products.
Another subject of the invention is a non-therapeutic process for treating the skin and/or mucous membranes and/or the scalp, in particular a make-up process, which consists in applying a composition as defined above to the skin and/or mucous membranes and/or the scalp.
Admittedly, it is known practice to use antiperspirants in compositions such as deodorants. However, nobody has hitherto used these agents for make-up compositions on the face probably
