Description

COSMETIC COMPOSITION COMPRISING SCATTERING FILLER AND NACRES

TECHNICAL FIELD

The present invention relates to compositions for caring for and/or making up the skin, which is especially intended to impart luminosity and healthy glow effect. The terms "luminosity"' and "light effect" are understood according to the invention to mean the characteristic of light reflection, diffuse and continuous reflection over the skin. Indeed, the skin naturally reflects a portion of the incident light. The "light effect" according to the invention makes it possible to increase this reflection, which gives the makeup a more luminous and more radiant look. The compositions according to the invention may also impart a healthy glow effect. The expression "healthy glow effect" is understood to mean a natural coloration of the skin, with an improvement in the dull appearance of the complexion (desaturating or chromatic and anti- dull complexion effect).

The expression "composition for caring for and/or making up keratin materials" according to the invention is understood to mean compositions different from rinse-off cleansing compositions. In particular, they will be compositions for caring for and/or making up the skin of the face and/or of the body, especially facial skin.

BACKGROUND ART

For centuries, consumers around the world, especially in Asia, are in search of novel cosmetic products for improving the appearance of keratin materials and especially the skin, in particular the surface appearance (visible and/or tactile unevenness) and/or the skin complexion, an external sign of a healthy glow, health and youth.

Moreover, to bring the keratin materials, especially the skin a luminous and healthy glow effect, it is necessary to hide the imperfection on skin, and at the same time scatter the light so as to bring to the skin a glow and at the same time non-shiny look. It is well known in the prior art to use pigments in a cosmetic composition to hide skin imperfection and brighten the skin. However, the pigment particles which have strong light scattering and absorption tend to accumulate inside the pores and enhance their visibility. US2005163730 from Unilever describes the association of silicon elastomer, ZnO nanopigment and scattering filler such as Ti0₂ coated mica or bismuth oxychloride. Therefore there remains the need to find novel care and/or makeup products, especially for the complexion, which give a luminous effect, without being shiny, which do not mark the relief while covering the defects (dyschromia, marks) or which give a unified colour to the face, in particular a natural and unified colour to the face, advantageously a healthy glow effect.

DISCLOSURE OF INVENTION

The inventors have found that scattering fillers, especially Bismuth compounds, combining with nacres, exhibit a very good light refection and making up effect, which meet the purpose of the current invention.

The hydrophilic properties of the scattering compounds helps the composition of the current invention affinitive to the skin, and enhances the adherence of the composition of the current invention.

According to one specific embodiment, a cluster crystal structure scattering filler is used in the current invention. The composition as such becomes adherent and less transparent due to the structure of the scattering filler. Consequently, the composition brings to the skin a light scattering effect so as to give a glow but not shiny look, and at the same time covers the imperfection of the skin.

Furthermore, thanks to the structure of the scattering filler mentioned above, the composition of the current invention can absorb sebum on the skin after application.

In one aspect, the current invention provides a cosmetic composition for caring for and/or making up keratin materials, in particular the skin of the face, comprising, in a physiologically acceptable medium:

(a) at least one scattering filler having a particle size of less than 35 pm, preferably between 2 pm and 35 pm, more preferably between 11 pm and 17 pm,

(b) at least a red or pink nacre, and

(c) at least a blue nacre.

The current invention as described above provides a good balance between the at least one scattering filler and thenacres, so as to enable the composition of the current invention to bring a coverage to the imperfection of the skin, as well as luminous and glow effect to the skin, especially to the facial skin.

According to the current invention, the composition may be in various forms, in particular in the form of an anhydrous composition, dispersion or emulsion, especially such as a water/oil or oil/water emulsion or multiple emulsion.

According to another embodiment, the composition of the current invention further comprises at least one additional colorant selected from the group consisting of goniochromatic colouring agents, photochromic colouring agents, fluorescent agents, optical brighteners, lakes, organic pigments, composite pigments, and mixtures thereof.

According to yet another specific embodiment, the composition of the current invention further comprises at least one additional filler. According to yet another embodiment, the composition of the current invention further comprises at least one organic UV sunscreen ingredient being an organic and/or an inorganic UV sunscreen ingredient.

In yet another aspect, the invention relates to a method for caring for and/or making up keratin materials, comprising the application to said keratin materials, in particular to the skin, of a composition according to the invention, for example in the form of a coat of composition or several layers of composition applied to facial skin, used alone or in combination with another composition (two-step application), said composition according to the invention being applied before and/or after the application of a care composition or of a makeup composition such as a foundation.

In particular, the application of said composition to the skin, especially facial skin, provides the latter with a luminous and healthy glow effect.
