example 1

[0492] Example 1: Solid anhydrous composition formed from colored particles alone according to the invention

[0493] Composition A

[0494]

[0495] * Pigment = yellow iron oxide, brown iron oxide, red iron oxide, black iron oxide, titanium dioxide, alone or as a mixture.

[0496] In the remaining examples, different compositions designated P1 to P4 type A were prepared using the following substances:

[0497]P1 = Composition A with yellow iron oxide (Sunpuro Yellow Iron Oxide (Sunpuro Yellow Iron Oxide) C33-9001, sold by Sun),

[0498] P2 = Composition A with red iron oxide (Sunpuro Red Iron Oxide (Sunpuro Red Iron Oxide) C33-8001, sold by Sun Corporation (Sun) Corporation),

[0499] P3 = Composition A with black iron oxide (Sunpuro Black Iron Oxide (Sunpuro Black Iron Oxide) C33-7001, sold by Sun Corporation (Sun) Corporation),

[0500] P4 = Composition A with titanium dioxide (Hombitan FF Pharma, sold by Sachtleben).

example 2

[0505] Example 2: Comparative example about dispersant content

[0506] Four compositions a, b, c and d (defined in the table below) formed solely from colored particles according to the invention were prepared according to the protocol defined in the specification.

[0507]

[0508] Cremophor A25 It is formed from oxyethylenated (25OE) cetearyl alcohol.

[0509] The pigment used in this example was red iron oxide identical to those used in Example 1.

[0510] The solid anhydrous compositions thus obtained according to the invention, formed mainly of colored particles, are subsequently mixed with demineralized water at room temperature as described below, in order to observe the self-dispersing properties of the pigments they contain.

[0511] To do this, they are first added to a flask containing 150 ml of deionized water, the concentration of the pigment being 0.01% by weight relative to the total weight of the solution obtained.

[0512] Subsequently over time, at ...

[0523] Example 3: Comparative example about foaming system content

[0524] Four compositions e, f, g and h (defined in the table below) formed solely from colored particles according to the invention and as defined in the table below were prepared according to the protocol defined in the description.

[0525]

[0526] The pigment used in this example was red iron oxide, consistent with those used in Example 1.

[0527] The solid anhydrous compositions thus obtained were then mixed with demineralized water as described in Example 2 at room temperature in order to observe the self-dispersing properties and particle size of the pigments they contained.

Abstract

A cosmetic product includes at least: a first anhydrous cosmetic composition including at least coloring particles that are solid at room temperature and atmospheric pressure, the particles being formed from: at least one hydrophilic dyestuff in a content of greater than or equal to 60% by weight relative to their total weight, at least one effervescent system in a content of less than or equal to 20% by weight relative to their total weight, at least one hydrophilic binder, and at least one dispersant that is different from the hydrophilic binder; and a second composition comprising at least one aqueous phase.

Description

technical field [0001] The present invention relates to a cosmetic product, in particular a care, hygiene and / or make-up product for keratinous materials, comprising at least two compositions, one comprising at least one aqueous phase and the other is anhydrous and can be combined directly by the user with the composition comprising at least one aqueous phase for the purpose of imparting a personalized color according to personal preference. [0002] The product according to the invention is in particular a product intended for use on keratinous materials, especially the skin. [0003] In particular, the product according to the invention may be any type of cosmetic product, such as foundations, foundation powders, eyeshadows, cosmetic products for concealment, blushers, lipsticks, lip balms, lip glosses, lip liners, eyeliners, eyeliners, Mascara, body makeup products, skin coloring products, care products such as treatment creams, tinting creams or anti-sun products.
