COSMETIC OR DERMATOLOGICAL COMPOSITIONS CONTAINING MICROSPHERES FIELD OF THE INVENTION The present invention relates generally to cosmetic or dermatological compositions comprising a microsphere and a film-forming component. These compositions have improved cosmetic or dermatological properties and characteristics, such as, for example, increase in the length and / or volume of eyelashes, improvement in the retention of the shape or curl of the hair / eyelashes, opportunity that the hair or eyelashes are Form the original style without reapplying a styling composition of the hair or eyelashes and / or heat, or increasing the properties of transfer resistance, waterproofing and / or prolonged durability.

Background of the Invention Fixation of keratin materials such as hair and eyelashes in place is an important element in styling, and this generally comprises either fixing a shape that has already been styled, or forming and fixing simultaneous of the keratin material. While stylization compositions currently on the market are generally effective in retaining the REF material: 180579 Keratin in a desired shape or configuration, many are not designed to allow the style to be subsequently modified to a desired shape or to re-form the original style without re-applying a stylization and / or heat composition. Additionally, under various stress classes, the styles resulting from the use of conventional products have a tendency to take an undesirable permanent decoration, which can not be easily modified. U.S. Patent No. 6,548,051 and U.S. Patent Application Publication Nos. 2002/0059941 and 2006/0024255 address these drawbacks of the traditional stylizing composition by providing re-formable styling compositions of the hair. While there have been pioneering advances in hair styling products through the introduction of re-formable hair care systems, further improvement remains desirable. They are still respectable, if there are no high goals, additional advances in the adjustment of the degree of adhesion and in the improvement of the overall appearance, sensation and maneuverability of the hair. Accordingly, one aspect of the present invention is a care and / or make-up composition and / or treatment for keratin materials such as hair, eyelashes, skin, lips and nails which it is capable of coping with. overcoming at least some of the problems generally associated with cosmetic or dermatological compositions, such as, for example, not allowing the reforming ability, poor resistance to transfer or adhesion, poor retention characteristics, etc.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of the invention.

Detailed Description of the Invention As used herein, the term "at least one" means one or more and thus includes individual components as well as mixtures / combinations. "Cosmetically acceptable medium" means a medium that is compatible with any keratin material, such as skin, hair, nails, eyelashes, eyebrows, lips and any other area of the body or facial skin. "Transfer resistance" as used herein refers to the quality exhibited by the compositions that are not easily removed by contact with another material, such as, for example, a lens, a cloth article or the skin, for example, when you eat or drink. Transfer resistance can be evaluated by any method known in the art for the evaluation thereof. For example, resistance to the transfer of a composition can be evaluated by a "kiss" test. The "kiss" test may include the application of the composition to human lips followed by the "kissing" a material, for example, a sheet of paper, after the expiration of a certain amount of time after the application, such as 2 minutes after the application. Similarly, the transfer resistance of a composition can be evaluated by the amount of product transferred from a user to any other substrate, such as the transfer from the neck of an individual to a collar after the expiration of a certain amount of time. time after the application. The amount of compositions transferred to the substrate (e.g., collar or paper) can then be evaluated and compared. For example, a composition may be resistant to transfer, if a majority of the product is left on the user, for example, lips, neck, etc. Additionally, the amount transferred can be compared to that transferred by other compositions, such as commercially available compositions. The compositions of "prolonged durability" as used herein, refers to compositions where at least one chosen property of consistency, texture and color remains the same as at the time of application, as seen by the naked eye, after a period of time. prolonged time, such as, for example, 1 hour, 2 hours, and additionally such as 8 hours. The properties of prolonged durability can be evaluated by any method known in the art for evaluate these properties. For example, prolonged durability can be evaluated by a test comprising the application of a composition to human skin (including the lips) and the evaluation of the consistency, texture and color of the composition after a prolonged period of time. For example, the consistency, texture and color of a lip composition can be evaluated immediately after application and these characteristics can then be re-evaluated and compared after an individual has used the lip composition for a certain amount of time. Additionally, these characteristics can be evaluated with respect to other compositions, such as commercially available compositions. "Impermeability" as used herein refers to the ability to repel water and permanence with respect to water. The waterproofing properties can be evaluated by any method in the art to evaluate these properties. For example, a mascara composition can be applied to false eyelashes, which can then be placed in water for a certain amount of time, such as, for example, 20 minutes. At the expiration of the pre-determined amount of time, false eyelashes can be removed from the water and passed over a material, such as, for example, a sheet of paper. The extent of the residue left in the material can then be evaluated and compared with other compositions, such as, for example, commercially available compositions. Similarly, for example, a composition can be applied to the skin, and the skin can be immersed in water for a certain amount of time. The amount of composition that remains on the skin after the pre-determined amount of time can then be evaluated and compared. For example, a composition can be waterproof if the majority of the product is left on the user, for example, on the eyelashes, skin, etc. "Stickiness" as used herein refers to the measurement of the maximum tensile force, Fmax, required as long as the two surfaces are separated. Depending on the contemplated application and the formulation being designed, the desirable value for Fmax may vary · In some embodiments, the substantially non-tacky compositions have an Fmax of less than about 4 Newton (N), less than about 1 N, less of about 0.5 N, less than about 0.3 N, less than about 0.2 N or less than 0.1 N. A person skilled in the art can determine the Fmax of the composition for example when determining the maximum tensile force, measured with a LLOYD type LR5K extensiometer, necessary to detach two surfaces. For example, two surfaces A and B of 38 mm2, which are solid, rigid, inert and non-absorbent, are mounted on movable mounts, which faces each other. Surfaces can move either by moving closer or farther away from each other, or one can move surface A independently of surface B or vice versa. Prior to insertion into the extensiometer, the surface A is coated with the composition to be measured, which can be dissolved in a solvent such as aqueous, hydroalcoholic, hydrocarbon, silicone and alcoholic solvents in a concentration of about 10 to about 30%, preferably 20%, the surface A is coated in a thickness of 1 to 10 thousandths of an inch (0.0254 to 0.254 mi), preferably 0.0254 mi (1 thousandth of an inch), and the surface is dried for 24 hours. hours at room temperature, for example 22 to 25 ° C, at a relative humidity of about 50%. Once inserted into the extensiometer, the surface A is subjected for 20 seconds to a compression force of 3 N against the surface B and then subjected for 30 seconds to the tensile force at a speed of 20 mm / minute. The amount of force, Fmax, necessary to obtain the initial separation is then signaled. An average Fmax is determined carrying out the process with multiple pairs, preferably at least six pairs, of the surface A and the surface B. The term "re-formable" means to provide a hair style (fixability) and / or retention that can be re-stored or modify without additional material or that heat is applied. This does not mean that additional product and / or heat can be applied. It may be desirable to add additional heat and / or styling compositions in terms of speed, ease of use, if the hair becomes too wet or soiled, if it is combed in excess, if it is brushed or handled, washed, or when the hair it's going to re-stylize dramatically. At least some of the compositions according to the invention must be re-formable, as judged by a professional hair stylist of ordinary skill, for at least 4 hours and up to 24 hours or more after the initial application. Preferably and only as an example, in order to restore or modify the style of the hair in case of "fall" or loss of fixation (disorder), no new materials are required, such as water or any form of fixing agent or heat . Other terms that can be synonymous with deformable include relocatable, removable, re-stylizable, rearrangeable and removable. The term "reformable" also means providing a hair style that can retain or maintaining a desired shape or configuration until water, heat, time and / or physical contact destroy the desired shape or configuration. The cosmetic compositions and methods of the present invention may comprise, consist of, or consist essentially of the essential materials and limitations of the invention described herein, as well as any additional or optional ingredients, components or limitations described herein or any other useful ingredient found in personal care compositions proposed for application to keratin materials. The composition of the present invention can be in any form. For example, it can be a paste, a solid or a cream. The composition of the invention can be transparent or clear, including for example, a composition without pigments. The composition can also be a molded or cast composition such as a bar or a disc. The composition in one embodiment is a solid such as a molded bar or a poured disk. The compositions of the present invention may be in the form of a lip composition such as a lipstick or liquid lip color, a foundation, a mascara product, a hair gel, a hair cream, or a hair spray (aerosol or non-aerosol).

As defined herein, stability is tested by placing the composition in a controlled environment chamber for 8 weeks at 25 ° C. In this test, the physical condition of the sample is inspected as it is placed in the chamber. The sample is then inspected again at 24 hours, 3 days, 1 week, 2 weeks, 4 weeks and 8 weeks. At each inspection, the sample is examined for compositional abnormalities such as phase separation if the composition is in the form of an emulsion. Stability is further tested by repeating the 8-week test at 40 ° C, 37 ° C, 45 ° C, 50 ° C and / or under freeze-thaw conditions. A composition is considered unstable if in any of these tests an abnormality is observed that impedes the functioning of the composition. The skilled person will easily recognize an abnormality that prevents the operation of a composition based on the proposed application.
