Description

Technical Field

[0001] Cross - reference to Related Applications This application claims priority to U.S. Patent Application No. 18 / 345,554, filed Jun. 30, 2023. This application also claims priority to French Patent Application No. 2311124, filed Oct. 16, 2023.

[0002] The present invention relates to an oil - in - water (o / w) emulsion (composition) comprising at least one hydrophobic modified polysaccharide compound and at least one aqueous - phase film - forming agent, and methods and kits containing such an emulsion composition in a container or during application. The composition has beneficial cosmetic properties, including, for example, properties as a primer or setter composition for good or improved durability, water and / or sebum resistance, and / or transfer resistance of separately applied compositions.

Background Art

[0003] Currently, in the market for keratin care and makeup, many products claim to withstand external factors such as water, sebum, mechanical friction, etc., and have long - lasting power throughout the day (water - proof mascara, hood - proof lipstick, long - lasting foundation). Long - lasting products for lips, eyelashes, eyebrows or face that can be used at home are mainly based on synthetic coating polymers in the presence of organic solvents. For compositions for lip makeup and face makeup, compositions containing unmodified silicone resins as film - forming agents, such as compounds with INCI name: trimethylsiloxysilicic acid or compounds with INCI name: polypropylsilsesquioxane, or silicone acrylate copolymers such as products with INCI name: acrylate / methacrylic acid polytrimethylsiloxy copolymer are known. On the other hand, long - lasting makeup products (mascara, eyeliner) for eyelashes and / or eyebrows typically use waxes or film - forming polymer particles (i.e., styrene / acrylate copolymers) in a latex - type aqueous suspension as film - forming agents.

[0004] Beyond these long-lasting products, the current trend is towards semi-permanent makeup. Specifically, in recent years, traditional makeup products have faced competition from the market for semi-permanent makeup offered in professional salons. This is encountered in the areas of eye makeup (semi-permanent mascara, permanent eyelash makeup, eyelash extensions, etc.), eyebrow makeup (semi-pigmentation, also known as microblading), complexion makeup (freckles, beauty spots, or full face makeup, or effects for a radiant or healthy complexion), or lip makeup (semi-permanent tattoos). This new trend has led consumers to increasingly demand longer-lasting effects for greater practicality (avoiding the need to apply and remove makeup daily, achieving a healthy complexion immediately upon waking, etc.).

[0005] The object of the present invention is to propose a composition that can extend the duration of cosmetic compositions on keratinous materials and improve the durability of cosmetic compositions on keratinous materials as well as their resistance to one or more external forces such as mechanical friction, water, sweat and perspiration, sebum, oil, etc., thereby providing the expected cosmetic effect, particularly excellent color retention of makeup on keratinous materials (skin, lips, nails, hair, eyelashes, eyebrows).

[0024] The general description above and the detailed description below are merely illustrative and descriptive, and should be understood not to limit the present invention. [Modes for carrying out the invention]

[0025] In the following description of the invention and the claims appended herein, terms used should be understood to have their common and conventional meanings in the art unless otherwise specified.

[0026] As used herein, "about" means within 10% of the indicated number (for example, "about 10%" means 9% to 11%, and "about 2%" means 1.8% to 2.2%).

[0027] As used herein, “a” or “an” means “at least one.”

[0028] "At least one" means one or more, and therefore includes individual components and mixtures / combinations.

[0029] When used herein, all provided ranges are intended to include any specific range within a given range, and combinations of subranges between given ranges. Thus, the ranges 1-5 specifically include 1, 2, 3, 4, and 5, as well as subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc.

[0030] As used herein, “film-forming agent,” “film-forming polymer,” or “film-forming agent” means, for example, a polymer or resin that leaves a film on a substrate after the solvent accompanying the film-forming agent has evaporated, been absorbed, and / or disappeared on the substrate to which it is applied.

[0031] As used herein, "wax" is a lipophilic aliphatic compound that is solid at ambient temperature (25°C), reversibly changes from a solid to a liquid state, has a melting point above 30°C, for example above 45°C, and a hardness above 0.5 MPa at ambient temperature.

[0032] "Surfactants" and "emulsifiers" are used interchangeably throughout this specification.

[0033] As used herein, “substituted” means including at least one substituent. Non-limiting examples of substituents include atoms, such as oxygen and nitrogen atoms, and functional groups, such as hydroxyl groups, ether groups, alkoxy groups, acyloxyalkyl groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen-containing groups, ester groups, thiol groups, sulfonate groups, thiosulfate groups, siloxane groups, and polysiloxane groups. Substituents may be further substituted.

[0034] As used herein, "volatile" means having a flash point of less than approximately 115°C.

[0035] As used herein, "non-volatile" means having a flash point above approximately 115°C.

[0036] As used herein, "polymer" means a compound composed of at least two monomers.

[0037] In this specification, “matte” refers to compositions with little or no light reflection. For example, a matte composition may have an average gloss value of 10 or less, e.g., 9, preferably 8, 6, 5, 4, or 1 or less, measured at 60°, and includes all and partial ranges in between, such as 1-10, 1-5, 2-10, 3-8, less than 1, less than 3, less than 5, etc. Such measurements can be performed by depositing the film to be tested onto a substrate (e.g., black scrub panel P121-10N or opaque card BYK No. 2810) using a drawdown bar (e.g., 1 mil, 3 mil, or 6 mil thickness) and an automated drawdown machine. The film can then be dried at room temperature and analyzed at a 60° angle using a gloss meter (BYK: micro-TRI-gloss).

[0038] As used herein, “contains no,” “substantially contains no,” or “lacks no” means that it is preferable that a particular component is not present in any amount in the composition, but it is possible that it may be present in very small amounts in the composition of the present invention, provided that these amounts do not significantly affect at least one, preferably most, of the advantageous properties of the conditioning composition of the present invention. For example, “contains no colorants” means that an effective amount (i.e., more than a trace amount) of colorants is omitted from the composition (i.e., about 0% by mass), “substantially contains no colorants” means that a colorant is present in an amount of 0.1% by mass or less, and “lacks no colorants” means that a colorant is present in an amount of 0.25% by mass or less relative to the total mass of the composition. The same nomenclature applies throughout this application and to all other components identified in this paragraph, even if not specifically stated for each identified component, such as silicone oil (compositions of the present invention that are “contains no silicone oil,” “substantially contain no silicone oil,” and “lacks no silicone oil” have the same meaning as described in this paragraph). Therefore, for example, "does not contain phenylated silicone oil" means that an effective amount (i.e., an effective amount to suppress matteness) of phenylated silicone oil is omitted from the composition (i.e., approximately 0% by mass), "substantially does not contain phenylated silicone oil" means that phenylated silicone oil is present in an amount of 0.25% by mass or less, and "lacks phenylated silicone oil" means that phenylated silicone oil is present in an amount of 0.5% by mass or less relative to the total mass of the composition.The same nomenclature applies throughout this application and to all other components identified in this paragraph, even if not specifically stated for each identified component, for example, (1) matte-finishing fillers (compositions of the present invention that are “matte-finishing filler-free,” “substantially matte-finishing filler-free,” and “lacking matte-finishing fillers”) and (2) additional film-forming agents other than hydrophobic-modified polysaccharide compounds and aqueous phase film-forming agents (compositions of the present invention that are “additional film-forming agent-free,” “substantially additional film-forming agent-free,” and “lacking additional film-forming agents”) having the same meaning as described in this paragraph. The descriptions of examples of the use of such language, as in this paragraph, are intended to be illustrative and not limiting.

[0039] As used herein, “makeup result” refers to a composition whose color, after a long period of time, remains the same or substantially the same as when applied, as observed with the naked eye. “Makeup result” can be evaluated by assessing long-term durability by any method known in the art to evaluate such properties. For example, long-term durability can be evaluated by a test involving applying the composition to a keratinous substance such as lips and evaluating the color of the composition after a long period of time. For example, the color of the composition can be evaluated immediately after application to a keratinous substance such as lips, and then these characteristics can be re-evaluated and compared after a certain length of time. Furthermore, these characteristics can be evaluated in relation to other compositions, e.g., commercially available compositions.

[0040] "Keratinous material" or "keratinous material" means skin such as natural nails, lips, face, body, hands, and the area around the eyes, as well as keratin fibers such as human hair, eyelashes, eyebrows, and body hair, and synthetic adducts such as false eyelashes, false eyebrows, and false nails.

[0041] "Physiologically acceptable" means that it is compatible with keratinous substances, has a pleasant color, scent, and feel, and does not cause any unacceptable discomfort (such as stinging pain or tightness) that would cause consumers to avoid using the composition. The compositions of the present invention may also be in the form of gel compositions.

[0042] A "gel composition" means a composition that does not flow like a liquid when applied to a substrate, i.e., a composition having a three-dimensional network structure that prevents the composition from spreading on the substrate or dripping off the substrate in a short time (e.g., less than 10 seconds) due to gravity after application. The storage modulus (G') is higher than the loss modulus (G'') over the entire strain range up to 300% strain. Preferably, G' (storage modulus) is higher than G'' (loss modulus) at low strain, but G' decreases and G'' increases, and the gel has a crossover point at a strain of >0.1%, preferably >1%, and preferably less than 200%, preferably less than 150%.

[0043] The "gel crossover point" (sol / gel point) refers to the point where G'' (loss modulus) intersects with G' (storage modulus), and is reported in strain %. This is the point where the composition transitions from a more solid state to a more liquid state. An example of a method for determining the gel crossover point is as follows: G'' (loss modulus) and G' (storage modulus) using a Discovery HR-3 rheometer by TA Instruments, with a 40 mm parallel plate geometry on a stainless steel flat Peltier plate. The test can be performed at 25°C with the following logarithmic sweep test parameters: strain % from 0.01 to 1000.0%. Five points per decade. Results are reported in strain %.

[0044] "Natural compounds" refer to any compounds that originate directly from natural substances, such as plants, without undergoing any chemical modification.

[0045] "Naturally occurring compounds" refer to any compound derived from a naturally occurring compound that has undergone one or more chemical modifications, for example, through an organic synthesis reaction, without altering the properties of the natural compound.

[0046] A "synthetic compound" refers to any compound that is neither a natural compound nor a compound of natural origin.

[0047] "Room temperature" means 25℃.

[0048] Atmospheric pressure is 760 mmHg, that is, 10 5 It means Pascal.

[0049] The compositions and methods of the present invention may consist of, or be essentially composed of, any essential elements and limitations of the present invention described herein, as well as any additional or optional components, components, or limitations described herein or otherwise useful. For example, the aqueous phase solvent system may essentially consist of water and C2-C5 monoalcohols, and / or the film-forming system of the composition may essentially consist of hydrophobic modified polysaccharide compounds and aqueous phase film-forming agents; similarly, the oil phase film-forming system may essentially consist of hydrophobic modified polysaccharide compounds.

[0050] For the purposes of the present invention, the "fundamental and novel properties" relating to compositions, components, and methods "essentially derived from" the specified components or actions is migration resistance.

[0051] Trademark names of substances, including but not limited to polymers and optional components, are referred to herein. The inventors herein are not intended to be limited to any substance described and referred to by a particular trade name. Substances equivalent to those referred to by a trade name (e.g., obtained from a different source under a different name or catalog (reference) number) may be substituted and used in the manner described herein and claimed.

[0052] All percentages and ratios are calculated by mass unless otherwise specified. All percentages are calculated based on the total mass of the composition unless otherwise specified. All component or composition levels relate to the activity level of that component or composition, excluding impurities that may be present in commercially available sources, such as residual solvents or by-products.

[0054] Aqueous phase-forming agent The present invention provides a composition comprising one or more aqueous film-forming polymers ("first film-forming polymer" or "first film-forming agent") which are nonionic, water-soluble or water-dispersible polymers. For clarity, "nonionic, water-soluble or water-dispersible" means that the polymer is nonionic. The polymer is also water-soluble or water-dispersible to such an extent that it can be easily stabilized throughout the vehicle (e.g., water) present in the composition.

[0055] One or more of these first film-forming polymers are part of an aqueous phase film-forming system. The aqueous phase film-forming system comprises, essentially, or can comprise, one aqueous phase film-forming agent.

[0059] In certain embodiments, monomers useful in forming these first film-forming polymers are polymerizable ethylenically unsaturated monomers having a cyclic amine residue or a cyclic amide residue. Therefore, the cyclic amide monomers of these first film-forming polymers may include cyclic amide residues that are heterocyclic ring structures or contain heterocyclic ring structures such as lactams. These may include α-lactams, β-lactams, γ-lactams, δ-lactams, and ε-lactams. In one preferred embodiment, the cyclic amide is pyrrolidone (γ-lactam), particularly vinylpyrrolidone.

One or more of these second film-forming polymers, together with at least one aqueous phase film-forming agent, are part of the composition film-forming system. Optionally, other film-forming agents may be present in the composition film-forming system if desired. Preferably, the at least one hydrophobic modified polysaccharide is at least one hydrophobic modified pullulan compound.

[0069] Pullulan is a naturally occurring polysaccharide produced from starch by the fungus Aureobasidium pullulans. Pullulan is an alpha-glucan primarily composed of linearly linked maltotriose repeating units connected via alpha-1,6-glycosidic bonds. Natural pullulan is readily soluble in cold or warm water, forming a clear, viscous solution.

[0165] Unless otherwise indicated, all numbers used in this specification and in the claims to represent quantities of components, reaction conditions, etc., should be understood in all cases to be modified by the term “approximately.” Therefore, unless otherwise indicated, the numerical parameters described in the following specification and in the appended claims are approximate values ​​that may vary depending on the desired properties to be obtained by the present invention.

[0166] The numerical ranges and parameters describing the broad scope of this invention are approximations, but the numerical values ​​described in the specific examples are reported as accurately as possible. However, each numerical value inherently contains a certain degree of error that inevitably arises from the standard deviation observed in each measurement. The following examples are intended to illustrate the invention and, as a result, do not limit its scope. Percentages are given on a mass basis. [Examples]

[0167] (Example 1) Sample of the present invention's composition

[0168] [Table 3]

[0169] (Example 2) Test protocol Migration resistance can be determined as follows:

[0170] Apply a controlled amount (e.g., 0.020 grams) of a color cosmetic composition (e.g., a foundation such as L'Oreal Paris Makeup True Match Liquid Foundation) to a controlled area (e.g., a 3cm x 3cm square) on a keratinous substance (e.g., skin). Allow the composition to dry for 5-15 minutes.

[0171] The test composition (setter) is applied in a controlled amount (e.g., the same amount as the applied color cosmetic composition, e.g., 0.020 grams) onto the applied color cosmetic composition and allowed to dry. If the test composition (setter) is not applied onto the color cosmetic, the migration resistance of the color cosmetic alone (without the setter composition) can be compared to the migration resistance when the setter composition is used in combination with the color cosmetic composition.

[0172] Next, a white cotton ball / pad sample is used to rub the area a specified number of times (e.g., 5 times or more) and the resistance of the color cosmetic composition to the ball / pad sample after such rubbing is evaluated. Resistance can be evaluated by determining the difference in the amount of color cosmetic composition transferred to the cotton ball / pad sample with or without the applied setting composition. Resistance is evaluated on a scale from 1 to 5, where 1 = minimal improvement in the resistance of the color cosmetic composition to the cotton ball / pad sample; 3 = moderate improvement in the resistance of the color cosmetic composition to the cotton ball / pad sample; and 5 = significant improvement in the resistance of the color cosmetic composition to the ball / pad sample, with little or no transfer of the color cosmetic composition to the cotton ball / pad sample occurring.

[0173] (Example 3) Migration resistance test Compositions A to J were prepared and tested as setter compositions for L'Oreal Paris Makeup True Match Liquid Foundation according to the protocol in Example 2.

[0174] Examples 3A to 3D were comparative examples that contained little to no hydrophobic-modified pullulan compounds and / or little to no aqueous film-forming agents.

[0175] Examples 3E to 3J were representative compositions of the present invention containing the indicated amounts and / or ratios of hydrophobic-modified pullulan compounds and aqueous film-forming agents.

[0176] The migration resistance of a commercially available foundation + prepared setter composition was determined according to the protocol in Example 2.

[0177] [Table 4]

[0178] [Table 5]

[0179] As can be seen, the setter composition corresponding to the present invention provided superior migration resistance when used in conjunction with commercially available foundation products, compared to comparative setter compositions that contained little to no hydrophobic-modified pullulan compounds and / or aqueous film-forming agents.

[0180] (Example 4) Similar to Example 3, the following setter compositions A to I of the present invention were prepared and used as setter compositions for L'Oreal Paris Makeup True Match Liquid Foundation according to the protocol in Example 2 to determine their migration resistance.

[0181] [Table 6]

[0182] [Table 7]

[0183] Similar to Example 3, setter compositions A to I of the present invention demonstrated excellent migration resistance when used in combination with commercially available foundation products, compared to comparative setter compositions that contain little to no hydrophobic-modified pullulan compounds and / or aqueous film-forming agents.
