Description

Title of the invention: OCULAR KERATINOUS MATTER COATING COMPOSITIONS FIELD OF INVENTION

[0001] The present invention relates to ocular keratin material coating compositions comprising water, at least one low glass transition temperature (Tg) film-forming agent, at least one secondary alcohol compound, in which a weighted average molecular weight / number of secondary alcohol groups ratio for the at least one secondary alcohol compound present in the composition is less than 69, and optionally at least one non-ionic amphiphilic thickening agent, as well as methods of using such compositions and kits containing such compositions. CONTEXT OF THE INVENTION

[0002] Eyelash compositions, such as mascaras, typically contain a wax that can add body and volume to the composition. Mascaras may also contain surfactants, particularly when in emulsion form. However, mascara formulations are typically created to minimize or mitigate the full effect of the properties of these ingredients, if any, in an attempt to achieve specific desired properties of the formulated mascara, such as volumizing, lengthening, easy removal, etc.

[0003] Furthermore, eyelash compositions, such as mascara compositions, tend to be of two types: (1) waterproof, long-lasting mascaras that are anhydrous, or (2) removable mascaras (e.g., removable with soap and water) that contain water. Generally, waterproof mascaras are not easily removed, and removable mascaras are not particularly long-lasting.

[0004] False (artificial) eyelashes can typically be applied to natural (real) eyelashes by means of adhesives (glue) or magnets.

[0005] For example, document WO2020180346 discloses magnetically attached eyelash prosthesis systems mediated by a magnetic mascara, document US 2016 / 0206031 discloses the use of magnetic materials, and document US 2019 / 0261715 discloses magnetic materials in an eyeliner-type composition.

[0006] With regard to adhesives or glues, US documents 2017 / 0027844, WO 2020 / 172746 and WO 2019 / 003454 are examples of references disclosing the use of such compounds for false eyelashes (artificial eyelashes).

[0007] US document 9 320 920 discloses eyelash makeup compositions, including false eyelashes (artificial eyelashes).

[0008] Document JP6190173 discloses an adhesive for false eyelashes which is black or dark-colored based on black after application, and which can be used in combination with an eyeliner by imparting a fast-drying adhesive layer to an application part containing (A) 30 to 70% by mass of a water-insoluble film-forming polymer; (B) 0.1 to 10% by mass of a carbon black; and (C) 0.01 to 15% by mass of a nonionic surfactant having an HLB of 10 or more.

[0009] There remains a need for improved cosmetic compositions having improved cosmetic properties which can be useful for coating ocular keratinous materials, for example for fixing false (artificial) eyelashes to natural (real) eyelashes, in particular compositions which do not contain traditional glues or adhesives or magnets, such as those used for the prior fixing of these artificial products to ocular keratinous materials.

[0010] Accordingly, one aspect of the present invention is a water-containing care and / or makeup and / or treatment composition for ocular keratinous materials that can be used to coat ocular keratinous materials for care, makeup, and / or to attach artificial structures (such as artificial eyelashes) to natural ocular keratinous materials. Summary of the invention

[0011] The present invention relates to ocular keratin coating compositions comprising water, at least one film-forming agent with a low glass transition temperature (Tg), at least one secondary alcohol compound, wherein a weighted average molecular weight / number of secondary alcohol groups ratio for the at least one secondary alcohol compound present in the composition is less than 69, and optionally at least one nonionic amphiphilic thickening agent. Preferably, the compositions are free from, substantially free from, or free of one or more of the following compounds: oils, waxes, surfactants, and / or colorants. Preferably, the compositions are free from, substantially free from, or free of at least two of the following compounds: oils, waxes, surfactants, and / or colorants, preferably at least three of these types of compounds, and preferably all four of these types of compounds.Preferably, the compositions are also free from, substantially free from, or free of hydrophilic thickening agents.

[0012] The present invention also relates to methods of caring for and / or making up real (natural) ocular keratinous materials by applying compositions of the present invention to natural ocular keratinous materials in a sufficient quantity to care for and / or conceal natural keratinous eye tissues.

[0013] The present invention also relates to methods of applying artificial ocular keratinous materials, such as artificial eyelashes or eyebrows, onto real (natural) ocular keratinous materials, including the application of compositions of the present invention onto natural ocular keratinous materials, the application of artificial ocular keratinous materials onto natural ocular keratinous materials onto which the compositions of the present invention have been previously applied, and allowing the compositions of the present invention to dry so that the artificial ocular keratinous materials adhere or bond with the natural ocular keratinous materials.

The "makeup result" can be evaluated by assessing the long-lasting properties using any method known in the art for evaluating such properties. For example, long-lasting performance can be assessed by a test involving the application of a composition to keratinous materials, such as ocular keratin, and the evaluation of the composition's color after a prolonged period of time. For example, the color of a composition can be evaluated immediately after application to keratinous materials, such as ocular keratin, and these characteristics can then be re-evaluated and compared after a certain time. Furthermore, these characteristics can be evaluated in relation to other compositions, such as commercially available compositions.

[0058] Polyesters can be obtained, in a known manner, by polycondensation of dicarboxylic acids with polyols, such as diols.

[0074] According to the present invention, compositions comprising at least one secondary alcohol compound are proposed.

[0075] “Secondary alcohol compound”, as used herein, means a compound containing at least one secondary alcohol group. "Secondary alcohol group" has its generally accepted meaning: the carbon atom to which the alcohol group is attached in a compound has only one hydrogen bonded. Specific examples of secondary alcohol compounds include, but are not limited to, compounds containing a single secondary alcohol group such as glycerin, 2-propanol, 2-butanol, 2-pentanol, 3-pentanol, etc.; compounds containing two secondary alcohol groups such as 2,3-butanediol, 2,3-pentanediol, etc.; glycols such as propylene glycol, butylene glycol, pentylene glycol, hexylene glycol, etc.; and compounds containing three or more secondary alcohol groups such as sorbitol, xylitol, erythritol, mannitol, etc.

[0076] According to the present invention, the secondary alcohol compound or mixture of secondary alcohol compounds present in the composition has (if only one secondary alcohol compound is present) or collectively has (if two or more secondary alcohol compounds are present) a molecular weight(s) such that the weighted average ratio of molecular weight / number of secondary alcohol groups for all secondary alcohol compounds present is less than 69, preferably 67 or less, preferably 64 or less, preferably 61 or less, preferably 60 or less, preferably 55 or less, preferably 50 or less, preferably 48 or less, and preferably 45 or less.

[0077] The "weighted average ratio of molecular weight to number of secondary alcohol groups" is calculated as follows, using sorbitol alone, propylene glycol alone, and sorbitol and propylene glycol present in a composition at a weight ratio of 1:1 for demonstration purposes:

[0078] Sorbitol: molecular weight = 182; number of secondary alcohol groups = 4. Ratio of molecular weight to number of secondary alcohol groups for sorbitol alone = 45.5

[0079] Propylene glycol: molecular weight = 76; number of secondary alcohol groups = 1. Ratio of molecular weight / number of secondary alcohol groups for propylene glycol alone = 76.

[0080] For a weight ratio of 1:1 between sorbitol and propylene glycol present in a composition, the "weighted average ratio of molecular weight / number of secondary alcohol groups" = [(45.5 x 1) + (76 x 1)) / (1 + 1) = 60.75.

[0081] Alternatively, and by way of example, for a weight ratio of 4:1 between sorbitol and butylene glycol (which has a molecular weight of 90 and 1 alcohol group) secondary), the "weighted average ratio of molecular weight / number of secondary alcohol groups" = [(45.5 x 4) + (90 x 1 )] / (4+l) = 54.4.

[0129] The compositions of the present invention can be prepared in the usual way for eyelash products. For example, the compositions of Example III (in bulk, 30 g) were prepared by rapid mixing at 2000 rpm for 1 minute using the Hauschild SpeedMixer DAC 400.1 FVZ. Example III - Essay A. Test Protocols

[0130] 1. Pegosity

[0131] Tackiness is an indicator of the initial adhesion properties of a composition. Tackiness was evaluated on a continuum from 1 to 5 by assessing the sample's ability to adhere upon contact with human skin. representative on the continuum being 1 = low tackiness (not sticky), 3 = some tackiness (some resistance when removing the finger from the surface of the film) and 5 = high tackiness (sticky, finger difficult to remove from the surface of the film).

[0132] To evaluate the tackiness, 1 g of product was weighed in a weighing pod and left to air dry overnight (24 hours) under ambient conditions or under a fume hood to prepare each film. After drying, a finger was pressed onto each film, then pulled upwards, and the force required to separate the finger from the film was measured on the continuum from 1 to 5 noted above.

[0133] 2. Adhesion

[0134] Adhesion is an indicator of the wear properties of a composition. Adhesion has been evaluated on a continuum from 1 to 5 by assessing the ability of the sample to be removed from a container, the representative points on the continuum being 1 = low adhesion (easy to remove), 3 = some adhesion (some resistance to removal) and 5 = high adhesion (difficult to remove).

[0135] To evaluate adhesion, approximately 1 g of each composition was poured into a polystyrene weighing pod and left to dry overnight under ambient conditions or under a fume hood. The adhesion of the dried composition to the weighing pod was determined by removing the film from the pod, measuring the force required to remove the film from the pod's surface.

[0136] 3. Cohesion

[0137] Cohesion is an indicator of the strength properties of a composition. Cohesion was assessed on a continuum of 1 to 5 by evaluating the ability of the sample to tear when stretched; representative points on the continuum were evaluated on a scale of 1 to 5, with 1 = low cohesion (film easily tears when stretched), 3 = some cohesion (partial tearing of the film when stretched) and 5 = high cohesion (no tearing of the film when stretched).

[0138] To assess cohesion, approximately 1 g of each composition was poured into a weighing pod and left to dry overnight under ambient conditions or under a fume hood. The cohesion of the dried composition was determined by removing a segment of film from the weighing pod and measuring the force required to create a break or tear in that segment. B.
