Description

Title of the invention: EMULSION COMPOSITIONS CONTAINING A HYDROPHOBICALLY MODIFIED POLYSACCHARIDE COMPOUND AND AN AQUEOUS-PHASE FILM FORMER FIELD OF INVENTION

[0001] The present invention relates to oil-in-water (o / w) emulsions (compositions) comprising at least one hydrophobically modified polysaccharide compound and at least one aqueous-phase film-forming agent, as well as methods and kits comprising such emulsion compositions in one or more containers or in application. The compositions have beneficial cosmetic properties, including, for example, as primer or fixative compositions for good or improved hold, water and / or sebum resistance, and / or transfer resistance, compared to compositions applied separately. DISCUSSION OF THE CONTEXT

[0002] Currently, in the keratin-based skincare and makeup market, many products claim to offer all-day wear and resistance to external factors such as water, sebum, mechanical friction, etc. (waterproof mascara, meal-resistant lipsticks, long-lasting foundations). Long-lasting products for lips, eyelashes, eyebrows, or face, which can be used at home, are primarily based on synthetic coating polymers in the presence of organic solvents.For lip makeup and face makeup compositions, there are known formulations containing an unmodified silicone resin as a film-forming agent, such as the compound with the INCI name: Trimethylsiloxysilicate or a compound with the INCI name: Polypropylsilsesquioxane, or alternatively, a silicone acrylate copolymer such as the product with the INCI name: Acrylates / polytrimethylsiloxymethacrylate copolymer. Long-lasting makeup products for eyelashes and / or eyebrows (mascaras, eyeliners) typically use waxes or film-forming polymer particles in aqueous suspension of the latex type (i.e., styrene / acrylate copolymers) as film-forming agents.

[0003] In addition to these long-lasting products, the current trend is towards semi-permanent makeup. Specifically, in recent years, traditional makeup products have found themselves competing with the semi-permanent makeup market in professional salons. This is found in the eye makeup sector (semi-permanent mascara, permanent eyelash makeup, eyelash extensions, etc.), Eyebrows (semi-permanent pigmentation, also known as blade pigmentation), complexion (freckles, beauty marks, or the entire face, for a healthy glow or radiant complexion), or lips (semi-permanent tattooing). This new trend is driving consumers to seek increasingly longer-lasting results for greater convenience (avoiding daily makeup application and removal, a healthy glow from the moment they wake up, etc.).

[0004] The object of the present invention is to propose compositions which offer excellent persistence of the expected cosmetic effects, in particular of the color of the makeup on keratinous materials (skin, lips, nails, hair, eyelashes, eyebrows) which can prolong the duration of the cosmetic composition on keratinous materials, as well as improve the hold of the cosmetic composition on keratinous materials and its resistance to external forces such as one or more of the following: mechanical friction, water, sweat and perspiration, sebum, oil, etc.

[0005] Any associated patent references include: • US 11 253 462 discloses low-wax compositions containing silicone polymers among other ingredients; • US 2020 / 0022898 discloses film-forming compositions comprising a first random copolymer of anionic or non-ionic non-crosslinking polyacrylate and a second random copolymer of cationic non-crosslinking polyamide; • US 11,033,478 discloses a self-curling mascara composition containing at least about 7% by weight of a water-soluble or water-dispersible nonionic copolymer that includes a cyclic amide monomer, a cyclic amine monomer, and an acrylamide monomer; • US 2003 / 0082221 discloses compositions containing pullulan; • US 2016 / 0113860 discloses compositions containing silicone-modified pullulan and silicone oils that it thickens; • JP-A H08-208989 is referred to in the previous application, and characterized by the disclosure of silicone-modified pullulan which thickens silicone oil components, but which has an inadequate thickening effect; • CN 111801092 discloses compositions for the impregnation of a material, where the compositions contain PEG or polyether modified silicones and dendrimer-type siloxanes; • FR 3 104 958 discloses compositions containing polyurethane dispersions among other ingredients; and • FR 3 110 849 discloses compositions containing polyurethane and / or acrylic dispersions among other ingredients, with little or no fat.

[0006] There remains a need for improved compositions such as primer compositions or fixative having improved properties with regard to the ease and / or comfort of application of the composition, and / or in particular with regard to improved properties related to better adhesion of the cosmetic composition to keratinous materials and its resistance to external forces such as mechanical friction, water, sweat and perspiration, sebum and / or oil.

[0022] “Surfactant” and “emulsifier” are used interchangeably throughout throughout this report.

[0023] “Substitute” as used herein means comprising at least one substitute. Non-limiting examples of substituents include atoms, such as oxygen and nitrogen atoms, as well as 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.

[0026] “Polymer” as used herein means a compound that is made up of at least two monomers.

[0027] “Mat” in compositions as used herein refers to compositions having little or no light reflection. For example, matte compositions may have average gloss properties, measured at 60°, less than or equal to 10, e.g., 9, preferably less than or equal to 8, 6, 5, 4, or 1, including all intermediate ranges and sub-ranges such as 1 to 10, 1 to 5, 2 to 10, 3 to 8, less than 1, less than 3, less than 5, etc. Such measurements may be performed by depositing films to be tested onto a substrate (e.g., a black exfoliating P121-10N panel or a BYK No. 2810 opacity card) using a necking bar (e.g., 1 mil, 3 mil, or 6 mil thick) and an automatic necking machine. The films can then be dried at room temperature and analyzed using a glossometer (BYK: micro-TRLgloss) at an angle of 60°.

[0028] “Exempt” or “substantially exempt” or “devoid of” as used herein This means that although it is preferable for no quantity of the specific component to be present in the composition, it is possible for very small quantities of it to be present in the compositions of the invention, provided that these quantities do not materially affect at least one, preferably most, of the advantageous properties of the revitalizing compositions of the invention. Thus, for example, "dye-free" means that an effective quantity (i.e., greater than trace amounts) of dye is omitted from the composition (i.e., about 0% by weight), "substantially dye-free" means that a dye is present in quantities not exceeding 0.1% by weight, and "dye-free" means that a dye is present in quantities not exceeding 0.25% by weight, relative to the total weight of the composition.The same nomenclature applies to all other ingredients identified throughout the application and in this paragraph, such as, for example, silicone oils (compositions of the invention which are "free of silicone oils", "substantially free of silicone oils" and "oil-free" have meanings consistent with the discussion within this paragraph), even if they are not specifically referred to for each identified ingredient.Thus, for example, "free from phenylated silicone oil" means that an effective amount (i.e., an effective amount of dullness inhibition) of phenylated silicone oil is omitted from the composition (i.e., about 0% by weight), "substantially free from phenylated silicone oil" means that phenylated silicone oil is present in amounts not exceeding 0.25% by weight, and "free from phenylated silicone oil" means that phenylated silicone oil is present in amounts not exceeding 0.5% by weight, relative to the total weight of the composition.The same nomenclature applies to all other ingredients identified throughout the application and in this paragraph, such as, for example, (1) mattifying fillers (compositions of the invention that are "free of mattifying fillers," "substantially free of mattifying fillers," and "devoid of mattifying fillers") and (2) additional film-forming agents other than the hydrophobically modified polysaccharide compound and the aqueous-phase film-forming agent (compositions of the invention that are "free of additional film-forming agents," "substantially free of additional film-forming agents," and "devoid of additional film-forming agents"). These terms have meanings consistent with the discussion in this paragraph, even if they are not specifically invoked for each identified ingredient. The examples of the use of such language as those in this paragraph are intended to be provided by way of illustration, not limitation.

[0029] The "makeup result" as used herein refers to compositions where the color remains the same or substantially the same as at the time of application, as seen with the naked eye, after a prolonged period of time. The "makeup result" Longevity can be assessed by evaluating the properties of a product using any method known in the art for evaluating such properties. For example, longevity can be assessed by a test involving the application of a composition to keratinous materials such as the lips and evaluating the color of the composition after an extended period. For instance, the color of a composition can be evaluated immediately after application to keratinous materials such as the lips, 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 ones.

[0030] “Keratinous material” or “keratin material” means natural nails, the lips, skin such as that of the face, body, hands and the area around the eyes, and keratin fibers such as hair, eyelashes, eyebrows, human hair, as well as synthetic additions, such as false eyelashes, false eyebrows, false nails, etc.

[0031] “Physiologically acceptable” means compatible with keratinous material and having a pleasant color, odor, and feel, and which does not cause unacceptable discomfort (tingling or pulling) likely to discourage a consumer from using the composition. The compositions of the present invention may be in the form of a gel composition.

[0032] The term “gel composition” means a composition that does not flow like a liquid when applied to a substrate, a composition that has a three-dimensional network that prevents the composition from spreading on, or flowing off, a substrate after application due to gravity over a short period of time (e.g., less than 10 seconds). G' (storage modulus) is greater than G” (loss modulus) in all stress ranges up to a stress of 300%. Preferably, G' (storage modulus) is greater than G” (loss modulus) at low stress, but with G' decreasing and G” increasing, and the gel exhibits the crossover point at > 0.1% stress, preferably > 1% stress, and preferably less than 200% stress, preferably less than 150% stress.

[0033] The expression "freeze crossing point" (Sol / Fel point) means the point at which G" (loss modulus) intersects G' (storage modulus), reported as a % stress. This is the point at which a composition transitions from a more solid to a more liquid state. An example of a method for determining a freeze crossing point is as follows: G" (loss modulus) and G' (storage modulus) using a TA Instruments Discovery HR-3 rheometer, having a parallel plate geometry of 40 mm on a flat stainless steel Peltier plate. The test can be performed at 25 °C with an angular frequency test parameter of 1.0 rad / s and a logarithmic sweep: % stress from 0.01 to 1000.0%. 5 points per decade. Results reported as a % of constraint.

[0034] “Natural compound” means any compound derived directly from a natural substance such as a plant without having undergone any chemical modification.

[0037] “Ambient temperature” means 25 °C.

[0038] “Atmospheric pressure” means 760 mmHg, i.e. 105 pascals.

[0039] The compositions and methods of the present invention may comprise, consist, or consist essentially of the essential elements and limitations of the invention described herein, as well as any additional or optional ingredient, component, or limitation described herein or otherwise useful. For example, the aqueous-phase solvent system may "consist essentially of" water and a C2-C5 monoalcohol, and / or the film-forming system of the composition may consist essentially of the hydrophobically modified polysaccharide compound and the aqueous-phase film-forming agent; similarly, the oil-phase film-forming system may consist essentially of the hydrophobically modified polysaccharide compound.

[0040] For the purposes of the present invention, the "fundamental and innovative property" associated with compositions, components and processes that "consist essentially of" identified ingredients or actions is resistance to transfer.

[0041] Reference is made herein to trade names of materials comprising, but not limited to, optional polymers and components. The inventors herein do not intend to limit themselves to the materials described and referenced by a particular trade name. Equivalent materials (for example, those obtained from a different source under a different name or catalogue (reference) number) to those referenced by a trade name may be substituted and used in the processes described and claimed herein.

[0042] All percentages and ratios are calculated by weight unless otherwise stated. All percentages are calculated on the basis of the total weight of a composition unless otherwise stated.

[0139] According to preferred embodiments, the compositions of the present invention contain a total dry matter content (excluding film-forming agents) of 10% by weight or less, preferably 5% by weight or less, or preferably 3% by weight or less relative to the weight of the composition. Preferably, the compositions of the present invention are devoid of, free from, or substantially free from dry matter (excluding film-forming agents).

[0140] A person skilled in the art shall ensure that the optional additional additives and / or their quantity are selected so that the advantageous properties of the composition according to the invention are not, or substantially not, compromised by the envisaged addition.

[0141] These substances can be selected in various ways by the person of profession in order to prepare a composition that has the desired properties, for example, consistency or texture.

[0142] It goes without saying that the composition of the invention must be cosmetically or dermatologically acceptable, that is to say, it must contain a physiologically acceptable non-toxic carrier and must be able to be applied to the keratinous material of human beings.

[0143] According to preferred embodiments of the present invention, methods for caring for and / or making up keratinous material are proposed by applying compositions of the present invention to the keratinous material in a sufficient quantity to care for and / or make up the keratinous material. Similarly, preferred embodiments of the present invention include methods for priming keratinous material for a cosmetic composition and / or for fixing a cosmetic composition that has been previously applied to keratinous material by applying compositions of the present invention over the keratinous material before applying a cosmetic composition (primer) and / or by applying compositions of the present invention over a cosmetic composition previously applied to the keratinous material (fixation).Preferably, the cosmetic composition used in conjunction with the compositions of the present invention is a coloured cosmetic composition.

[0144] Preferably, the "makeup" of the keratinous material includes the application of at least one coloring agent to the keratinous material (either in the composition itself or in a color layer composition applied either over or under the composition as described above) in sufficient quantity to give color to the keratinous material.

[0145] According to particularly preferred embodiments of the present invention, methods for applying makeup to keratinous material such as skin are proposed, comprising (1) applying a colored cosmetic composition such as a foundation to the keratinous material (e.g., skin), (2) allowing the colored cosmetic composition to dry on the keratinous material (e.g., skin), preferably allowing it to dry for about 1 minute to about 15 minutes, preferably for about 5 minutes to 10 minutes, and (3) applying a composition of the present invention over the dried colored cosmetic composition that has been applied to the keratinous material (e.g., skin).Preferably, compositions of the present invention are applied over the dried color cosmetic composition in a sufficient quantity to improve the transfer resistance of the color cosmetic composition compared to the transfer resistance provided by the color cosmetic composition when applied alone to a keratinous material.

[0146] According to preferred embodiments of the present invention, kits comprising, as separate compositions in one or more containers within the kits, (A) at least one composition of the present invention, in particular a cosmetic fixative or primer composition, comprising at least one hydrophobically modified polysaccharide compound and at least one aqueous-phase film-forming agent; and (B) at least one other composition such as a cosmetic composition comprising at least one colorant are proposed.

[0151] Unless otherwise stated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the description and claims shall be understood as modified in all cases by the term "approximately". Consequently, unless otherwise stated, the numerical parameters presented in the following descriptive document and the attached claims are approximations that may vary depending on the desired properties that one seeks to obtain by means of the present invention.

[0152] Although the numerical ranges and parameters presenting the broad scope of the invention are approximations, the numerical values ​​presented in the specific examples are reported as accurately as possible. However, every numerical value inherently contains some errors necessarily resulting from the standard deviation found in their respective measurements. The following examples are intended to illustrate the invention without thereby limiting its scope. Percentages are given on a weight basis. EXAMPLES

[0153] Example 1 - Samples of inventive compositions

[0155] The resistance to transfer can be determined as follows.

[0156] A colored cosmetic composition (for example, a foundation such as L'Oréal Paris Makeup True Match Liquid Foundation) is applied to a keratinous material (for example, the skin) in a controlled quantity (for example, 0.020 grams) in a controlled area (for example, a 3 cm x 3 cm square). Wait 5 to 15 minutes until the solution has dried.

[0157] Apply a test composition (fixative) in a controlled amount (for example, the same amount as the applied cosmetic color composition, such as 0.020 grams) over the applied cosmetic color composition and allow it to dry. If a test composition (fixative) is not applied over the cosmetic color, the transfer resistance of the cosmetic color alone (without fixative composition) can be compared to the transfer resistance when a fixative composition is used in conjunction with the cosmetic color composition.

[0158] A white cotton swab / ball is then used to rub the area a specified number of times (e.g., 5 times or more) to assess the resistance to transfer of the color cosmetic composition onto the swab / ball after such rubbing. The resistance to transfer can be evaluated by determining the difference in the amount of color cosmetic composition transferred onto the swab / cotton ball with and without the fixing composition applied.Transfer resistance is assessed on a scale of 1 to 5, with 1 = minimal improvement in the transfer resistance of the color cosmetic composition onto the pad / cotton ball; 3 = moderate improvement in the transfer resistance of the color cosmetic composition onto the pad / cotton ball; and 5 = significant improvement in the transfer resistance of the color cosmetic composition onto the pad / cotton ball, with little or no transfer of the color cosmetic composition onto the pad / cotton ball.
