Definitions

• the present invention generally relates to compositions for keratin materials (hair or eyelashes) such as, for example, mascaras comprising at least one polar modified wax and at least one liposoluble or dispersible rheological polymer.
• Such compositions when applied to keratin materials, can impart synergistically improved volume or thickening to the keratin materials.
• Such compositions can also possess improved properties and characteristics such as, for example, improved transfer-resistance of the composition, improved waterproofing characteristics, and/or improved long- wear properties.
• cosmetic compositions particularly mascaras, which possess significantly improved cosmetic properties, particularly with respect to volumizing or thickening eyelashes.
• one aspect of the present invention is a makeup, care and/or treatment composition for keratin materials such as hair or eyelashes which is able to provide significantly improved volumizing or thickening properties to the keratin materials.
• compositions for keratin materials for example, hair or eyelashes
• mascaras comprising at least one polar modified wax and at least one liposoluble or dispersible rheological polymer.
• the present invention also relates to methods of increasing the volume (thickness), strength and/or length of keratin materials (for example, hair or eyelashes) comprising applying to the keratin material a keratin material volume-, strength- and/or length-increasing effective amount of a composition comprising at least one polar modified wax and at least one liposoluble or dispersible rheological polymer.
• the present invention further relates to methods of making-up keratin materials comprising applying a keratin material making- up effective amount of a composition comprising at least one polar modified wax and at least one liposoluble or dispersible rheological polymer to keratin materials in need of such making-up.
• the present invention also relates to methods of inhibiting or reducing flaking off of a composition which has been applied to a keratin material (for example, hair or eyelashes) comprising combining at least one polar modified wax and at least one liposoluble or dispersible rheological polymer prior to application.
• a keratin material for example, hair or eyelashes
• the present invention also relates to methods of treating or caring for keratin materials by applying compositions of the present invention to the keratin materials in an amount sufficient to treat and/or care for the keratin materials.
• the present invention further relates to methods of enhancing the appearance of keratin materials by applying compositions of the present invention to the keratin materials in an amount sufficient to enhance the appearance of the keratin materials.
• the present invention also relates to methods of making a composition comprising mixing at least one liposoluble or dispersible rheological polymer with at least one polar modified wax to form a composition.
• the expression “at least one” means one or more and thus includes individual components as well as mixtures/combinations.
• Transfer resistance refers to the quality exhibited by compositions that are not readily removed by contact with another material, such as, for example, a glass, an item of clothing or the skin, for example, when eating or drinking. Transfer resistance may be evaluated by any method known in the art for evaluating such. For example, transfer resistance of a composition may be evaluated by a modified "kiss” test. The modified "kiss" test may involve application of the composition to human eyelashes followed by "kissing" or rubbing a material with the eyelashes, for example, a sheet of paper, after expiration of a certain amount of time following application, such as 2 minutes after application.
• transfer resistance of a composition may be evaluated by the amount of product transferred from a wearer to any other substrate, such as transfer from the eyelashes of an individual to clothing after the expiration of a certain amount of time following application.
• the amount of composition transferred to the substrate e.g., clothing or paper
• a composition may be transfer resistant if a majority of the product is left on the eyelashes.
• the amount transferred may be compared with that transferred by other compositions, such as commercially available compositions.
• Long wear compositions refers to compositions where at least one property chosen from consistency, texture, and color remains the same as at the time of application, as viewed by the naked eye, after an extended period of time, such as, for example, 1 hour, 2 hours, and further such as 8 hours.
• Long wear properties may be evaluated by any method known in the art for evaluating such properties. For example, long wear may be evaluated by a test involving the application of a composition to eyelashes and evaluating the consistency, texture and color of the composition after an extended period of time. For example, the consistency, texture and color of a mascara composition may be evaluated immediately following application and these characteristics may then be re- evaluated and compared after an individual has worn the mascara composition for a certain amount of time. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions.
• Waterproof refers to the ability to repel water and permanence with respect to water. Waterproof properties may be evaluated by any method known in the art for evaluating such properties. For example, a mascara composition may be applied to false eyelashes, which may then be placed in water for a certain amount of time, such as, for example, 20 minutes. Upon expiration of the pre-ascertained amount of time, the false eyelashes may be removed from the water and passed over a material, such as, for example, a sheet of paper. The extent of residue left on the material may then be evaluated and compared with other compositions, such as, for example, commercially available compositions.
• a mascara composition may be applied to false eyelashes, which may then be placed in water for a certain amount of time, such as, for example, 20 minutes. Upon expiration of the pre-ascertained amount of time, the false eyelashes may be removed from the water and passed over a material, such as, for example, a sheet of paper. The extent of residue left on the material may then be evaluated and compared with other compositions
• a composition may be applied to skin, and the skin may be submerged in water for a certain amount of time. The amount of composition remaining on the skin after the pre-ascertained amount of time may then be evaluated and compared.
• a composition may be waterproof if a majority of the product is left on the wearer, e.g., eyelashes.
• Tackiness refers to the adhesion between two substances. For example, the more tackiness there is between two substances, the more adhesion there is between the substances. To quantify “tackiness,” it is useful to determine the "work of adhesion” as defined by IUPAC associated with the two substances. Generally speaking, the work of adhesion measures the amount of work necessary to separate two substances. Thus, the greater the work of adhesion associated with two substances, the greater the adhesion there is between the substances, meaning the greater the tackiness is between the two substances.

• Suitable emulsion forms include but are not limited to oil-in-water, water-in- oil, oil-in-water-in-oil, water-in-oil-in-water and nanoemulsions (emulsions whose oil globules are of very fine particle size, that is to say that they have a number-average size of less than about 100 nanometers (nm)).
• Emulsions contain at least one oil phase and at least one aqueous phase.
• emulsions contain surfactants or surfactant-like materials which provide stability to the emulsions and inhibit de-phasing of the emulsions.
• composition of the invention can also comprise any additive usually used in the field under consideration.
• dispersants such as poly(12-hydroxystearic acid), antioxidants, essential oils, sunscreens, preserving agents, fragrances, fillers, neutralizing agents, cosmetic and dermatological active agents such as, for example, emollients, moisturizers, vitamins, essential fatty acids, surfactants, pasty compounds and mixtures thereof can be added.
• emollients such as, moisturizers, vitamins, essential fatty acids, surfactants, pasty compounds and mixtures thereof
• additional components can be found in the other references which have been incorporated by reference in this application. Still further examples of such additional ingredients may be found in the International Cosmetic Ingredient Dictionary and Handbook (9 th ed. 2002).
• These substances may be selected variously by the person skilled in the art in order to prepare a composition which has the desired properties, for example, consistency or texture.
• These additives may be present in the composition in a proportion from 0% to 99% (such as from 0.01 % to 90%) relative to the total weight of the composition and further such as from 0.1 % to 50% (if present), including all ranges and subranges therebetween.
• composition of the invention should be cosmetically or dermatologically acceptable, i.e., it should contain a nontoxic physiologically acceptable medium and should be able to be applied to the eyelashes of human beings.
• Non-limiting examples of such additional components include non-volatile oils such as silicone oils (for example, dimethicone, phenyl trimethicone, trimethyl pentaphenyl trisiloxane, etc) or hydrocarbon oils (for example, esters).
• non-volatile oils such as silicone oils (for example, dimethicone, phenyl trimethicone, trimethyl pentaphenyl trisiloxane, etc) or hydrocarbon oils (for example, esters).
• the compositions of the present invention are substantially free of silicone oils (i.e., contain less than about 0.5 % silicone oils).

• the compositions are substantially free of non-volatile oils (i.e., contain less than about 0.5% non-volatile oils).
• methods of increasing keratin material for example, hair or eyelash
• keratin material for example, hair or eyelash
• a keratin material volume-, strength- and/or length-increasing effective amount of a composition comprising at least one polar modified wax and at least one liposoluble or dispersible rheological polymer are provided.
• the compositions may be applied to the keratin materials as needed, preferably once or twice daily, more preferably once daily and then preferably allowed to dry before subjecting to contact such as with clothing or other objects.
• sufficient polar modified wax is combined with sufficient liposoluble or dispersible rheological polymer such that the performance properties of the compositions are greater than the performance properties of compositions containing either ingredient individually (that is, synergism exists with respect to the at least one polar modified wax and at least one liposoluble or dispersible rheological polymer).
• a composition provides to a keratin material (for example, hair or eyelashes) after or upon application to the keratin material comprising combining at least one polar modified wax and at least one liposoluble or dispersible rheological polymer prior to application.
• a keratin material for example, hair or eyelashes
• Such a combination of the required elements in a single composition at any time prior to application of the composition to the keratin material results in increasing of the volume, strength and/or length of the keratin material after application to the keratin material.
• methods of making-up keratin materials comprising applying a keratin material making-up effective amount of a composition comprising at least one polar modified wax and at least one liposoluble or dispersible rheological polymer to keratin materials in need of such making-up are provided.
• "making up" the keratin material includes applying at least one coloring agent to the keratin material in an amount sufficient to provide color to the keratin material
• compositions of the present invention are provided.
• compositions of the present invention by applying compositions of the present invention to the keratin materials in an amount sufficient to enhance the appearance of the keratin materials are provided.
• compositions of the present invention are applied topically to keratin materials (for example, hair or eyelashes) in an amount sufficient to treat, care for and/or make up the keratin materials, or to enhance the appearance of the keratin materials.
• the compositions may be applied to eyelashes as needed, preferably once or twice daily, more preferably once daily and then preferably allowed to dry before subjecting to contact such as with clothing or other objects.
• compositions having improved cosmetic properties such as, for example, improved feel upon application (for example, deposit), flake resistance, long wear, transfer resistance or waterproof properties are provided.
• improved properties may also be chosen from improved flexibility, wearability, drying time or retention as well as reduced tackiness or migration over time
• polar modified wax is in an an oil phase
• liposoluble or dispersible rheological polymer is in an aqueous phase
• the liposoluble or dispersible rheological polymer and the polar modified wax are combined when the aqueous phase and the oil phase are combined.
• Such preferred procedures can allow, among other things, the preparation of emulsions which are substantially or essentially free of surfactants, if desired.
• methods of inhibiting or reducing flaking off of a composition which has been applied to a keratin material comprising combining at least one polar modified wax and at least one liposoluble or dispersible rheological polymer in the composition prior to application are provided.
• a keratin material for example, hair or eyelashes
• Such a combination of the required elements in a single composition at any time prior to application of the composition to the keratin material results in inhibition and/or reduction of flaking off of the composition from the keratin material after application to the keratin material.
