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. Consumers now use specific gestures to create a "blurring effect" on their lips, i.e. "progressively" coloring their lips. This requirement cannot be easily achieved by using conventional silicone elastomers and fillers. At the same time, the pigment level will greatly affect the blurring effect. Therefore, there is a need to develop a lipstick capable of providing a matte, uniformly colored cosmetic effect with a blurring effect. Disclosure of Invention It is therefore an object of the present invention to develop a composition which is capable of providing a matt, uniformly coloured cosmetic effect with a blurring effect on keratin materials, in particular the lips. It is a further object of the present invention to provide a non-therapeutic method for caring for and/or making up keratin materials, in particular the lips, which is capable of providing a matte, uniformly coloured make-up effect with a blurring 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 first filler having an oil absorption of at least 300 g oil/100 g; c) At least one second filler having an oil absorption of 40-140 g oil/100 g, and D) More than 5% and less than 14% by weight of at least one pigment, relative to the total weight of the composition. The inventors have found that in the case of a combination of the above components a) to d), the composition according to the invention is capable of providing a matt, homogeneously coloured cosmetic effect with a blurring 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.
