Description

COSMETIC COMPOSITIONS COMPRISING WAX DISPERSIONS [0002]

The present disclosure relates to a composition comprising a film forming agent and a wax dispersion and optionally a thermoreversible gelling polymer. The present disclosure also relates to a method of increasing the volume of keratinous fibers and a method of improving the ease of removal of the composition.

Consumer products, such as cosmetics and personal care products, can use ingredients that enable these products to form films or coatings on a variety of substrates, such as keratinous substrates (e.g., hair and skin). The inclusion of film formers in cosmetic compositions can improve various properties such as gloss, stickiness and long wear.

In particular, the use of latex film formers among cosmetic and personal care products such as mascara compositions, hair styling products, topical foundations, sunscreen compositions and water based nail enamels is known. For example, U.S. Patent Application No. 13 / 341,875 discloses a latex film former for use in a nail composition. Latex and latex blends have been used to provide long-term wear properties of the product in which they are formulated. For example, conventional washable mascara compositions can use latex film formers in combination with water-in-oil emulsions. Additionally, long-wearing mascara compositions comprising a latex film-forming agent are disclosed, for example, in U.S. Patent Application No. 61 / 541,173; 61 / 542,131; And 61 / 542,136, all of which are incorporated herein by reference.

 However, cosmetic and personal care products incorporating latex film formers, such as long-wearing mascara compositions, typically exhibit difficulty in removing from the keratinous substrate to which they are applied, which is at least in part a latex film former . Thus, there is a need in the art to provide long-wearing cosmetics and personal care products that are more easily removed by consumers.

In addition, consumers are looking for cosmetic compositions that enable them to increase the perception of the volume of keratinous materials they want to make and care. For example, in the case of mascara you want a volume effect on your eyelashes. Traditionally, this is accomplished by using a composition having a high solids content, to provide the material to the keratinous fibers and thus to obtain a makeup result that is somewhat imparted with volume or load. However, there remains a need for new methods of imparting increased volume to keratinous materials.

It has now been surprisingly found that incorporation of the wax dispersion and optionally thermally reversible gelling polymer into a composition comprising a latex film former can improve the ease of removal of the composition from the keratinous substrate and / It was found that the volume of the sex fibers can be increased.
