The present invention relates to a composition comprising at least one glitter-type aluminum pigment and at least one glitter-type black pigment, for making up a keratinous substance such as the skin, and to a cosmetic process using the same.

art background

Cosmetic make-up compositions comprising pigments and colorants for keratinous substances are widely used as, for example, foundation powder, finishing powder, face powder, blush and eye shadow. These compositions are used to give keratinous substances an attractive appearance. Therefore, in order for the cosmetic compositions to be able to serve as make-up cosmetics, the aesthetic effects, such as the effects of giving a natural finish and three-dimensional appearance effects to keratinous substances, preferably the skin, in particular the skin of the face, are very important. In order to impart such aesthetic effects to cosmetic compositions, the use of several effect pigments in the compositions has been proposed.

For example, JP-A-H7-228509 discloses a make-up cosmetic composition containing aluminum-treated powder produced by coating plate-like inorganic powder with aluminum powder by a mechanical process.

JP-A-2010-83727 also discloses a scaly iron oxide particle having a magnetite structure, an average length of 5 to 30 μm in a direction of a plate surface, and an average length of 0.05 to 0.5 µm in a thickness direction.

JP-A-2010-222295 also discloses a cosmetic composition comprising a flake-like black iron oxide having an average particle diameter of 5 to 100 µm and a thickness of 0.2 to 0.3 µm, wherein the surface of the flake-like black iron oxide is coated with at least one of hydrated or anhydrous inorganic oxides of silicon, aluminum, titanium, zirconium, tin or the like.

JP-T-2010-513619 also discloses platelet-like aluminum pigments having a narrow thickness distribution and at least partially coated with lubricant, wherein the pigments have a) an average thickness h ₅₀ of 15 nm to 75 nm as determined by scanning electron microscope thickness count, b) a relative width of thickness distribution Δh of 30% to less than 70%, as determined by scanning electron microscope thickness count and as calculated on the basis of the corresponding cumulative restitution curve of the relative frequencies of appearance, according to the formula Δh=100×(h ₉₀ - h ₁₀ )/h ₅₀ , and c) an X-ray diffractogram, measured on pigments in substantially plane-parallel orientation, showing one or two main peaks that do not correspond to reflections [111].

JP-A-2005-307155 also discloses glossy black interference pigments comprising a mixture of different substrates having (A) a coating of Fe ₃ O ₄ , (B) a colorless coating consisting of one or more layers each having an index of refraction n≤1.8, (C) optionally a coating with a high refractive index absorbing material which covers only part of the underlying surface, and optionally (D) an outer protective layer.

JP-T-2014-508211 also discloses a black effect pigment comprising a) at least a partial layer of SnO ₂ and/or hydrated SnO ₂ on a substrate, b) at least a partial layer of Fe ₃ O ₄ , and c) optionally, another metal oxide layer, preferably the metal oxide layer is transparent, in which the at least partial layer of Fe ₃ O ₄ may additionally contain ferric hydroxide and Fe ₂ O ₃ .

- Reflective particles

By "reflecting particles" is meant particles whose size, structure, in particular the thickness of the layer(s) of which they are composed and their physico-chemical nature, as well as their surface condition, allow them to reflect incident light. This reflection may, where appropriate, have sufficient intensity to create on the surface of the composition or the mixture, when it is applied to the support to be constituted, highlight points visible to the naked eye, i.e. i.e. brighter points which contrast with their environment by appearing to sparkle.

These particles may have various shapes and may in particular be in the form of platelets or globules, in particular in spherical form.

The reflective particles, whatever their shape, may or may not have a multilayer structure and, in the case of a multilayer structure, may have, for example, at least one layer of uniform thickness, in particular made of a reflective material.

When the reflective particles do not have a multilayer structure, they may be composed, for example, of metal oxides, in particular of titanium or iron oxides obtained by synthesis.

When the reflective particles have a multilayer structure, they may comprise, for example, a natural or synthetic substrate, in particular a synthetic substrate at least partially coated with at least one layer of a reflective material, in particular with at least one metal or metallic material. The substrate can consist of one or more organic and/or inorganic materials.

More particularly, it can be chosen from glasses, ceramics, graphite, metal oxides, aluminas, silicas, silicates, in particular aluminosilicates and borosilicates, and synthetic mica, and mixtures thereof, this list not being exhaustive.
