Description

Composition for caring for and/or making up keratin materials Technical Field The present invention relates to a composition for caring for and/or making up keratin materials. More particularly, the present invention relates to compositions for caring for and/or making up the lips. The invention also relates to a non-therapeutic method for caring for and/or making up keratin materials. Background Lipsticks have been used for many years to enhance the positive aspects of the lips of users. Lipstick can change facial features visible to the user. In addition to changing the shape of the lips, the lipstick may be made in various colors and hues to promote a desired effect or to express the emotion of the user. To date, some prior art documents have been published concerning cosmetic compositions for making up and/or caring for the skin and/or lips. Lipsticks that provide a matte cosmetic effect are favored by consumers. For most matte lipsticks, an oil absorbing filler and silicone elastomer are used to create a matte, smooth effect to evenly color the entire lip without color differences. For some lipsticks used to provide a matte effect on the lips, some of them are prone to breaking or are too soft, and some are too dry, which is undesirable. Thus, there is a need to develop a lipstick that is not frangible or too soft and that is capable of providing a matte, uniformly colored, oil-free and dry cosmetic effect. Disclosure of Invention It is therefore an object of the present invention to develop a lipstick which is not frangible or too soft and which is capable of providing a matt, uniformly coloured, oil-free and dry cosmetic effect. It is another object of the present invention to provide a non-therapeutic method for caring for and/or making up the lips which does not tend to break or become too soft and which is capable of providing a matt, uniformly coloured, non-oily and non-dry make-up effect. Thus, according to a first aspect, the present invention provides a composition, preferably for caring for and/or making up keratin materials, comprising: a) At least one silicone elastomer resin; b) At least one hydrophobic silica, and C) At least one sugar ester selected from the group consisting of C 1-C30 monoesters and polyesters of sugar. The inventors have found that in the case of the combination of components a) to c) described above, the composition according to the invention does not tend to break off or is too soft and is capable of providing a matt, homogeneously coloured, oil-free and dry cosmetic effect. According to a second aspect, the present invention provides a non-therapeutic method for caring for and/or making up keratin materials, comprising the application to the keratin materials of a composition as described above. Other subject matter and features, aspects, and advantages of the present invention will become more apparent upon reading the following description and examples. Detailed description of the invention Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. To the extent that the term definition in the present specification conflicts with the meaning commonly understood by one of ordinary skill in the art to which this invention pertains, the definition set forth herein controls. Hereinafter, and unless otherwise indicated, the endpoints of the numerical ranges are included within the range, in particular in the expressions "." and "slave. In" the right. Furthermore, the expression "at least one" as used in the present specification is equivalent to the expression "one or more". In the present disclosure, the term "comprising" should be interpreted as encompassing all the specifically mentioned features as well as optional, additional, unspecified features. As used herein, use of the term "comprising" also discloses embodiments (i.e., "consisting of") that do not have features other than the specifically mentioned features. Unless otherwise indicated, all numbers expressing quantities of ingredients and the like used in the specification and claims are to be understood as being modified by the term "about". Accordingly, unless indicated to the contrary, the numerical values and parameters set forth herein are approximations that can vary depending upon the desired purposes. All percentages in the present invention refer to weight percentages unless otherwise indicated. As used herein, the term "keratin materials" refers to the skin and lips.
