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.

The expression "one or more" as used herein means one or more, and therefore includes mixtures / combinations as well as individual components.

"Cosmetic acceptable medium" means a medium that is compatible with any keratin materials such as skin, hair, nails, eyelashes, eyebrows, lips and any other area or facial skin of the body.

As used herein, "moving resistance" refers to a property exhibited by a composition that is not easily removed, for example, by eating or drinking, for example by contact with another substance such as glass, clothing items or skin. Movement resistance can be evaluated by any method known in the art for evaluating such. For example, the migration resistance of the composition can be assessed by a "kiss" test. A "kiss" test may include applying the composition to a human lips and then "kissing" a substance, eg, a piece of paper, after a period of time, such as two minutes after application, after application. Similarly, the migration resistance of the composition can be assessed by the amount of product transferred from the place of application to any other substrate, such as from one person's neck to the collar, after a period of time after application. The amount of composition transferred to the substrate (eg, feather or paper) can then be assessed and compared. For example, if the majority of the product remains on the application site, such as lips, neck, etc., the composition will be transfer resistant. In addition, the shifted amount can be compared to the shifted amount of another composition, such as a commercially available composition.

As used herein, a "persistent" composition is one in which one or more properties selected from concentration, texture and color are at the point of application when visually observed after a long time, such as, for example, one hour, two hours, or even eight hours. It refers to a composition that remains the same. Persistence can be assessed by any method known in the art for evaluating the above characteristics. For example, persistence can be assessed by a test that includes applying the composition to human skin (including lips) and assessing the concentration, texture, and color of the composition after a long time. For example, the concentration, texture, and color of the lip composition can be assessed immediately after applying it, and the lip composition can be retained for a period of time before reevaluating these characteristics. In addition, these properties can be evaluated for other compositions such as commercially available compositions.

As used herein, "waterproof" refers to water repellency and water resistance. Waterproofing can be assessed by any method of evaluation thereof known in the art. For example, the mascara composition can be applied to the false eyelashes and then placed in water for a certain time, for example 20 minutes. At the expiration of the predetermined time, the false eyelashes can be removed from the water and passed over a material such as, for example, a piece of paper. The extent of residue left on the material can then be evaluated and compared with other compositions, such as, for example, commercially available compositions. Similarly, for example, the composition may be applied to the skin and the skin may be submerged in water for some time. Then, the amount of the composition remaining on the skin after the predetermined time can be evaluated and compared. For example, if the majority of the product remains at the site of application, such as eyelashes, skin, etc., the composition will be waterproof.

As used herein, "adhesiveness" refers to determining the F _max , the maximum tensile force required, while separating the two faces. Depending on the expected application and the formulation to be designed, the desired F _max value may vary. In some embodiments, the substantially non-tacky composition has an F _max of less than about 4 Newton (N), less than about 1 N, less than about 0.5 N, less than about 0.3 N, less than about 0.2 N or less than 0.1 N. . One skilled in the art can determine the F _max of the composition by measuring with an extensiometer of the LLOYD model LR5K type the maximum traction required to remove the two faces.

For example, two 38 mm ² faces, A and B, which are solid, rigid, inert and non-absorbent, are mounted on a movable plate facing each other. The two faces may be movable toward or away from each other, or a person may move the A plane independently of the B plane or vice versa. Before inserting into the extensometer, the A side is dissolved in a concentration of about 10 to about 30%, preferably 20% in a composition to be measured (aqueous, hydroalcoholic, hydrocarbon, silicone and alcoholic solvents, etc.) Coating the A side to a thickness of 1 to 10 mils, preferably 1 mil, and the side for about 24 hours at a relative humidity of about 50% and at room temperature, such as 22-25 ° C. To dry. When inserted into this extensometer, a compressive force of 3 N is applied to the A plane against the B plane for 20 seconds, and then a tensile force is applied at a rate of 20 mm / min for 30 seconds. Then record the amount of F _max, the force required to achieve the initial separation. The procedure is performed several times, preferably six or more times each for the A side and the B side, to determine the average F _max .

The term " modifiable " is meant to provide a restoring or alterable hairstyle (fixability) and / or retention without applying additional material or heat. This does not mean that no additional product and / or heat can be applied. When the hair becomes excessively damp or dirty, excessively combed, brushed or manipulated, cleaned, or when it is desired to redraw hair dramatically, heat and / or ease of use It may be desirable to add additional styling compositions. At least some of the compositions according to the invention should be judged by a professional hair stylist of ordinary skill and modified for at least 4 hours and up to 24 hours or more after the initial application. Preferably and simply do not require new materials or heat, such as water or any form of fixative, in order to restore or change the hairstyle, for example if the "slim" or the setting is broken (tangled). Do not. Other terms that may have the same meaning as "modifiable" include repositionable, remoldable, restyleable, rearrangeable, and remodellable. The term "modifiable" is also meant to provide a hairstyle that can retain or maintain the desired shape or shape until the desired shape or shape is destroyed by water, heat, time and / or physical contact.
