  A number of cosmetic compositions, including colored cosmetics such as foundations, concealers, lipsticks and mascaras, and other cosmetic and sunscreen compositions have been developed for long-lasting and transfer resistance. This is generally accomplished by using a composition that forms a film after application. Such compositions typically contain a volatile solvent that evaporates upon contact with the skin or other keratinous tissue, leaving a layer containing waxes and / or resins, pigments, fillers, and active agents. However, these compositions tend to be uncomfortable to the wearer because the composition remains as a brittle or inflexible film on the skin or other keratinous tissue. Further, such a composition may be supple or inflexible, and there is a possibility that there is no comfortable wearing feeling. Furthermore, such a composition has a sticky tendency, resulting in poor applicability, spreadability and sustainability.

Thus, there is a need for improved cosmetic compositions having improved cosmetic properties.
Accordingly, one aspect of the present invention is to care and / or make up keratin materials such as skin, hair, eyes, eyelids, nails and / or lips, which can solve or overcome at least one of the above-mentioned problems of conventional compositions. And / or in a composition for treatment.

It is understood that both the general description above and the following detailed description are exemplary and illustrative only and are not restrictive 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, a “film former” or “film forming agent” is the solvent that accompanies the film former after evaporation, absorption and / or dissipation on the substrate. , Means a polymer or resin that leaves a film on the applied substrate.

  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 “kiss” test. The “kiss” test applies the composition to human keratin materials, such as hair, skin or lips, and after application for a predetermined time, eg 2 minutes after application, to a material such as a paper sheet on the hair, skin or lips. It may include rubbing. Similarly, the transfer resistance of the composition is determined by the transfer from the wearer to any other substrate after a predetermined time following application to the hair, skin or lips, for example worn from the individual's hair, skin or lips. It can also be assessed by the amount of product transferred to the garment sack. The amount of composition transferred to the substrate (eg, candy or paper) may then be evaluated and compared. For example, if most of the product remains on the wearer's hair, skin or lips, the composition is said to be transfer resistant. Furthermore, the transferred amount may be compared to other compositions, such as commercially available compositions. In a preferred embodiment of the invention, the composition does not transfer from the hair, skin or lips to the substrate at all or little.

  As used herein, a composition having “long-lasting durability” refers to a composition that retains the same or substantially the same color tone as when applied to the naked eye after a long period of time. Called. 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 human hair, skin or lips and evaluating the color of the composition after a long period of time. For example, the color of the composition may be evaluated immediately after application to hair, skin or lips, and after a predetermined time, these characteristics may be re-evaluated and compared. In addition, these characteristics may be evaluated for other compositions, such as commercially available compositions.

  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 materials. 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.

  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 can then be evaluated and compared to other compositions, such as commercially available compositions. Similarly, for example, the composition may be applied to the skin and the skin may be soaked in water for a predetermined time. The amount of composition remaining on the skin after a predetermined time may then be evaluated and compared. For example, if most of the product remains on the wearer, such as eyelashes, skin, etc., the composition is said to be water resistant. In preferred embodiments of the invention, little or no composition is transferred from the wearer.

  The cosmetic compositions and methods of the present invention are intended for the essential elements and limitations of the present invention described herein, as well as any additional or optional ingredients, elements or limitations described herein, or topical application to the hair. Can contain, consist of, or consist essentially of any useful other useful in personal care compositions.

  The composition of the present invention may be liquid or non-liquid (semi-solid, soft solid, solid, etc.) and any form. For example, it may be a paste, a solid, a gel, or a cream. Furthermore, emulsions such as oil-in-water or water-in-oil emulsions, multiphase emulsions such as oil-in-water emulsions or water-in-oil-in-water emulsions, or hard or soft gels including solids, anhydrous gels, Good. The composition may be in a form selected from a translucent anhydrous gel or a transparent anhydrous gel. The composition of the present invention may contain, for example, an external or continuous fatty phase. The composition may be anhydrous. The composition can also be a molded composition or a molded article such as a stick or dish. In one embodiment, the composition is a solid such as a mold stick or a poured stick.

  Depending on the intended use, such as a stick, the hardness of the composition can be taken into account. The hardness of the composition may be expressed, for example, in gram weight (gf). The composition of the present invention may have a hardness in the range of, for example, 20 gf to 2000 gf, such as 20 gf to 900 gf, and even 20 gf to 600 gf.

  This hardness is measured in one of two ways. The first hardness test follows the method of inserting a probe into the composition and in particular using a texture analyzer (eg TA-XT2i from Rheo) equipped with an ebonitic cylinder of 25 mm height and 8 mm diameter. . The hardness measurement is performed at 20 ° C. at the center of 5 samples of the composition. A cylinder is introduced into each sample of the composition at a prespeed of 2 mm / s, then at a speed of 0.5 mm / s and finally at a postspeed of 2 mm / s, with a total displacement of 1 mm. The recorded hardness value is that of the maximum peak observed. The measurement error is ± 50 gf.

  The second hardness test cuts a stick-like composition with a diameter of 8.1 mm, preferably 12.7 mm, using an Indelco-Chatillon Co. DFGHS2 tension measuring instrument, and a speed of 100 mm / min. , A “cheese wire” method, including measuring hardness at 20 ° C. The hardness value of this method is expressed in grams of the shear force required to cut the stick under the conditions described above. According to this method, the hardness of the composition of the present invention in the form of a stick is, for example, in the range of 30 gf to 300 gf, for example 30 gf to 250 gf, in a sample of a stick with a diameter of 8.1 mm, and further a diameter of 12.7 mm In the stick sample, the range is, for example, 30 gf to 200 gf, and further 30 gf to 120 gf.

  The hardness of the composition of the present invention may be such that the composition is self-supporting and can easily disintegrate to form a satisfactory deposit on the keratin material. Further, this hardness can impart good impact strength to the composition of the present invention molded or molded in a stick-like or dish-like form, for example.

  One skilled in the art will evaluate and select the composition using at least one of the general hardness tests described above based on the desired hardness and the application considered. A composition falls within the preferred embodiments of the present invention if acceptable hardness is obtained from at least one of these hardness tests in view of the intended application.

  As is apparent, the hardness of the composition of the preferred embodiment of the present invention is such that, for example, the composition is advantageously self-supporting and can easily disintegrate to form a satisfactory deposit on the keratinous material. . Furthermore, due to this hardness, the composition of the present invention has good impact strength.

  In a preferred embodiment of the invention, the composition in the form of a stick has the properties of a deformable and flexible elastic solid and imparts significantly elastic flexibility when applied.

  As described herein, stability is 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. The samples are then examined again after 24 hours, 3 days, 1 week, 2 weeks, 4 weeks and 8 weeks. In each test, the sample is examined for composition abnormalities, such as phase separation if the composition is in the form of an emulsion, bending and tilting if the composition is in the form of a stick, melting or syneresis (or sweating). The stability is further tested by repeating the test for 8 weeks at 25 ° C., 37 ° C., 45 ° C. and under freeze-thaw conditions. If any of these tests reveals an anomaly 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.
