Cosmetic Article Comprising A Mesh

Abstract

The cosmetic product article including a solid block of cosmetic product with a breakage index measured at 20° C. of between 0.2 and 20 N, and at least one mesh, arranged such that the product passes therethrough and having through-holes, the largest dimension of which is between 50 and 300 μm.

Description

FIELD OF THE INVENTION[0001]The invention relates to a cosmetic article especially for the lips.BACKGROUND OF THE INVENTION[0002]A lipstick typically comprises a tube and a block of cosmetic product, also called the bullet, housed movably in vertical translation in the tube. The bullet formulation is chosen to obtain the best possible make-up result while ensuring that the bullet offers good strength, especially mechanical and thermal. The proportions of the four main components of the bullet, i.e. waxes, oils, butters and pigments, can therefore be adjusted. The waxes act as structuring elements.[0003]To obtain good make-up results, for example a better color, gloss or matt result, it is preferable to reduce the bullet solidity, for example by increasing the proportion of oils and butters. The formula obtained is then more flexible or more tender. However, this increase lowers the mechanical strength of the bullet, thereby making it more likely to break. In addition, this increase ...

Benefits of technology

[0009]In use, the block of product passes through the mesh which destructures a fraction of the product block such that it changes from a solid state to a pasty state. This state is particularly advantageous since it allows better application of the product. In case of a lipstick, this state allows the user to obtain a better color, gloss or matt result, for example.

[0010]Thus, the advantages of the solid form of the cosmetic product when it is not used and those of the pasty form in use are obtained, while avoiding the disadvantages of the solid form of the product in use, i.e. more difficult application of the product and less satisfactory make-up result, and the disadvantages of the pasty form of the product when it is not used, for example poorer mechanical properties and exudation phenomena.

[0011]The above-mentioned range of sizes of the largest hole dimensions produces good block destructuring results without the user having to apply too much force to obtain the dose required for make-up. Furthermore, the fact that the block is in a particularly solid form means that formulations offering particularly good gloss or mattness results can be used, these formulations not being compatible with a more flexible form of the block. Furthermore, it is particularly advantageous that the change from solid state to pasty state of the product, due to the above-mentioned characteristics of mechanical strength and size of the holes in the mesh, does not require any other operation on the product, for example a heating operation.

Problems solved by technology

However, this increase lowers the mechanical strength of the bullet, thereby making it more likely to break.

In addition, this increase favors exudation phenomena which not only alter the initial formulation of the bullet but also have a negative visual impact on the consumer.
