It is understood that both the general description above 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 expression "at least one" means one or more and thus includes individual components as well as mixtures / combinations.
As used herein, “transfer resistance” refers to the quality exhibited by a composition that is not easily removed by contact with other substances such as glass, clothing or skin, for example, by eating or drinking. Transfer resistance may be evaluated by any method known in the art for such evaluation. For example, the transfer resistance of a composition can be assessed by a modified “kiss” test. The modified “kiss” test involves applying the composition to human eyelashes and then rubbing or “kissing” the material, such as a paper sheet, and the eyelashes after a certain period of time following application, eg, 2 minutes after application. May be included. Similarly, the transfer resistance of a composition can also be assessed by the amount of product that has been transferred from the wearer to any other substrate, eg, from personal eyelashes to clothing, after a predetermined time following application. . The amount of composition transferred to the substrate (eg, clothing or paper) may then be evaluated and compared. For example, if most of the product remains in the eyelashes, the composition is said to be transfer resistant. Furthermore, the amount transferred may be compared to the amount transferred by other compositions, such as commercially available compositions.

  As used herein, a composition having “long-lasting” means that at least one property selected from consistency, texture, and color tone has a long duration, for example, 1 hour, as viewed with the naked eye. It refers to a composition that is maintained in the same manner as at the time of application after 2 hours and even after 8 hours. Persistence over time can be assessed by any method known in the art for assessing such properties. For example, long-lasting persistence can be assessed by a test that includes applying the composition to the eyelashes and assessing the consistency, texture, and color of the composition after a long period of time. For example, the consistency, texture, and color tone of the mascara composition may be evaluated immediately after application, and after an individual wears the mascara composition for a predetermined time, these characteristics may be reevaluated and compared. In addition, these characteristics may be evaluated for other compositions, such as commercially available compositions.

  As used herein, “water resistance” refers to the ability to repel water and resistance to water. Water resistance may be evaluated by any method known in the art for evaluating such properties. For example, the mascara composition may be applied to false eyelashes and then placed in water for a predetermined time, eg, 20 minutes. After a predetermined time has elapsed, the false eyelashes are removed from the water and passed onto a substance such as a paper sheet. The degree of residue remaining on the material may be assessed and compared to other compositions, such as commercially available compositions. Similarly, the composition may be applied to the skin and the skin immersed in water for a predetermined time. Then, after a predetermined time, the amount of the composition remaining on the skin may be evaluated and compared. For example, if most of the product remains on the wearer, such as the eyelashes, the composition is said to be water resistant.

  As used herein, “stickiness” refers to the adhesion between two substances. For example, the greater the adhesion between two materials, the greater the adhesion between the materials. In order to quantify “stickiness”, it is useful to measure “work of adhesion” as defined in IUPAC for two substances. Generally speaking, the work of adhesion measures the work required to separate two substances. Therefore, the larger the work of adhesion for the two substances, the greater the adhesion force between the substances, which means that the adhesion between the two substances increases.

  The work of adhesion, and thus stickiness, can be quantified using acceptable techniques and methods commonly used to measure adhesion, typically in forced time units (e.g. grams seconds (`` gs ")). For example, the Stable Micro Systems, Ltd. TA-XT2 is a TA-XT2 application study revised in January 2000, the entire contents of which are hereby incorporated by reference (see: It can be used to measure adhesion according to the procedure described in MATI / PO.25). According to this method, desired values for the work of adhesion of the substantially non-sticky material include less than about 0.5 gs, less than about 0.4 gs, less than about 0.3 gs, and less than about 0.2 gs. . Other similar methods known in the art can be used in other similar analyzers for measuring adhesion.

  The cosmetic compositions and methods of the present invention apply to the essential elements and limitations of the invention described herein, as well as any additional or optional ingredients, elements or limitations, or keratin materials described herein. It may contain, consist of, or consist essentially of any other useful ingredient found in the intended personal care composition.

  The compositions of the present invention can be used in any form suitable for use in straw, such as non-solid anhydrous, oil-free or emulsion compositions (e.g. water-in-oil emulsions, oil-in-water emulsions, multiphase emulsions (W / O / W or O / W / O), nanoemulsions, etc.). The composition of the present invention can be a mascara. Generally speaking, mascara contains a colorant such as a pigment. Furthermore, the compositions of the present invention may be clear or transparent: little or no colorant. The compositions according to the invention, in particular those containing little or no colorant, can be used as other products applied to the eyelashes and / or as base coats and / or top coats applied directly below.

  As described herein, stability was tested by placing the composition in a controlled environmental chamber at 25 ° C. for 8 weeks. In this test, the material state of the sample is inspected when placed in the chamber. Samples are then examined again at 24 hours, 3 days, 1 week, 2 weeks, 4 weeks and 8 weeks. In each test, the sample is examined for abnormalities in the composition, such as phase separation if the composition is in the form of an emulsion. The stability is further tested by repeating the test for 8 weeks at 40 ° C., 37 ° C., 45 ° C., 50 ° C. and / or freeze-thaw conditions. In any of these tests, if an anomaly is observed that interferes with the function of the composition, the composition is considered to lack stability. One skilled in the art will readily recognize anomalies that interfere with the function of the composition, based on the intended use.
