Description

Title of the invention: WATER-IN-OIL EMULSION COMPOSITION technical field

[0001] The present invention relates to the field of personal care and cosmetic products, in particular a makeup composition in the form of a water-in-oil emulsion. The present invention further relates to a method for applying makeup and caring for keratinous materials and, preferably, for concealing skin imperfections. CONTEXT

[0002] Many consumers wish to use cosmetic and personal care compositions that improve the appearance of keratinous materials and particularly of the skin, especially the optical cosmetic effect of the skin, such as the brightening effect, the coverage effect and the radiance effect of the skin.

[0003] The skin is not a smooth surface of uniform color and has raised areas or at least micro-reliefs, such as pores, wrinkles, fine lines, brown spots, scars, blemishes, black eyes, and dry patches, which create slight irregularities on the surface of the face. Furthermore, the complexion is not always satisfactory, for example, appearing dull. Cosmetic compositions, such as foundations and color correctors, are commonly used to give the skin an aesthetically pleasing color and also to enhance the appearance of uneven skin, by concealing blemishes and discolorations, reducing the visibility of surface imperfections such as pores and wrinkles, and hiding brown spots and acne marks.

[0004] In general, a color corrector has better coverage than a foundation, adheres better to the skin, and can conceal imperfections such as dark spots, scars, blemishes, and blackheads, resulting in a more even skin tone. Color correctors are either too thin or too thick to provide a natural finish, and therefore, many consumers want full coverage with a natural finish, long wear, a fresh feel, a lightweight feel with a smooth and creamy texture, good tackiness, good adherence to the skin, and a pleasant glide-on sensation during application. A wide variety of cosmetics have already been studied in this regard, but it is still technically difficult to achieve desirable concealing coverage in a single stable formulation.Therefore, there is a need for a composition, for example in the form of a complexion corrector, which can. to offer one or more benefits, including a full coverage effect with a natural finish, a desired freshness, and which is stable over a long period and a wide temperature range for its storage and use.

The terms and expressions used herein have meanings recognized and known to a person skilled in the art; however, for convenience and completeness, specific terms and expressions and their meanings are set out below.

[0014] As used here, the expression "at least one" is synonymous with "one or more" and thus includes individual components as well as mixtures / combinations.

[0015] The terms "include" and "comprehension" and related forms of these words are used in an inclusive and open sense, meaning that additional elements (or steps) may be included. They are not intended to be interpreted as "consisting solely of" or as excluding other elements or steps.

[0016] Furthermore, the term "including" is used to mean "including but not limited to". "Including" and "including but not limited to" are used interchangeably.

[0017] The expression "substantially free (of a component)", as used herein, refers to systems or compositions which do not contain any appreciable amount of the component, for example not more than about 1% by weight, or not more than about 0.5% by weight, or not more than about 0.3% by weight, such as not more than about 0.1% by weight, relative to the total weight of the system or composition according to embodiments of the invention.

[0018] The term “free” or the expression “totally free (of a component)”, as used herein, refers to systems or compositions which do not contain the component to any degree measurable by standard means.

[0019] The term “INCI” is an abbreviation for International Nomenclature of Cosmetic Ingredients, which is a system of names proposed by the International Nomenclature Committee of the Personal Care Products Council to identify the ingredients of cosmetic or personal care products.

[0020] The term "anhydrous", as used here, refers to a composition comprising less than 5% by weight of water, or even less than 2% by weight of water, or even less than 1% by weight of water relative to the total weight of the composition, or which is free of water.

[0021] The expression "keratinous material", as used here, refers to hair, skin, eyebrows, lips and nails, and more particularly to the skin of areas such as the face, cheeks, hands, body, legs and thighs, the area around the eyes and eyelids.

[0117] In the present invention, the cosmetic composition is substantially free of alkanes.

[0118] “Alkanes”, as used herein, means a volatile oil based on alkanes which is generally liquid in an environment at ordinary temperature and pressure (e.g., 25 °C, 1 atmosphere). Volatile alkane-based oils are linear or branched alkanes with 8 to 19 carbon atoms. "Linear" means that the carbons are bonded together in a straight-chain structure. "Branched" means that there is one or more branches of an alkyl group on the straight chain. Examples include nonane and decane. undecane, dodecane, tridecane, tetradecane, pentadecane, hexadecane, heptadecane, octadecane, nonadecane and their structural isomers (such as isododecane or isohexadecane) and any mixture thereof.

[0119] “Significantly exempt”, as used here, means that although it is preferable Even if no quantity of the specific component is present in the composition, it is possible that there may be small quantities of it 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 compositions of the invention. In some embodiments, "materially free" means less than approximately 2% of the identified ingredient, such as less than approximately 1%, or less than approximately 0.5%, based on the composition as a whole (or of a particular component, if specified). Fatty solid compound

[0120] The composition according to the invention may optionally comprise one or more fatty solid compounds. "Fatty solid compound" means a fatty substance that is solid at room temperature. In certain embodiments, the fatty solid compound (at room temperature and atmospheric pressure) may be selected from waxes, pastes, or mixtures thereof, more particularly from hydrocarbon-based waxes, pastes based on hydrocarbons, or mixtures thereof. Waxes

[0121] For the purposes of this invention, "wax" means a lipophilic compound which is solid at room temperature, having a melting point greater than or equal to 40 °C, and less than or equal to 120 °C, more particularly less than or equal to 90 °C.

[0122] For the purposes of the invention, the melting temperature (or melting point) corresponds to the temperature of the most endothermic peak observed in thermal analysis (DSC) as described in ISO 11357-3; 1999.

[0123] The melting point of a solid fatty compound can be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name "DSC 2000" by TA Instruments with the "TA Universal Analysis" software.

[0124] The measurement protocol is as follows:

[0125] A 5 mg sample of wax is placed in a crucible and subjected to an initial temperature rise from -20 °C to 120 °C at a heating rate of 10 °C / minute, then cooled from 120 °C to -20 °C at a cooling rate of 10 °C / minute, and finally subjected to a second temperature rise from -20 °C to 120 °C at a heating rate of 5 °C / minute. During the second rise of temperature, the melting point of the solid fat substance is measured, which corresponds to the temperature of the most endothermic peak of the observed melting curve.

[0126] More particularly, the wax can be chosen from polar waxes, in particular alcohol waxes; esters such as waxes of animal or vegetable origin, such as beeswax, lanolin, sunflower, candelilla, carnauba, rice bran, lignite, hydrogenated jojoba oil; waxes resulting from the hydrogenation of esters obtained from C6-C22 fatty alcohols of vegetable origin and vegetable oil; waxes of formula R1COOR2 in which RI and R2 represent linear, branched or cyclic aliphatic chains whose number of atoms varies from 10 to 50, which may contain a heteroatom, in particular an oxygen, and whose melting temperature varies from 40 to 120 °C; partial or total esters, preferably total, of a C16-C30 saturated carboxylic acid with glycerol, such as glyceryl tristearate or glyceryl tribehenate, glyceryl trihydroxystearate, and mixtures thereof.

[0127] We can also mention non-polar hydrocarbon waxes (i.e. made up solely of carbon and hydrogen atoms), resulting from the transformation of petroleum, such as, for example, paraffins, microcrystalline waxes, ozokerites, polyethylene waxes, polymethylene waxes (synthetic wax, Fischer-Tropsch), alone or in mixtures. Pasty compounds

[0128] For the purposes of this invention, "pasty compound" means a lipophilic compound comprising, at room temperature, a liquid fraction and a solid fraction. Thus, a pasty compound may have an initial melting point below 25 °C.

[0129] The melting point of the paste-like compound is determined according to the same principle as that detailed above for waxes. However, in the case of a paste-like compound, the measurement protocol is as follows:

[0130] A 5 mg sample of a paste-like compound placed in a crucible is subjected to a first temperature increase from -20 °C to 100 °C at a heating rate of 10 °C / minute, then cooled from 100 °C to -20 °C at a cooling rate of 10 °C / minute, and finally subjected to a second temperature increase from -20 °C to 100 °C at a heating rate of 5 °C / minute. The melting point of the paste-like compound is the temperature value corresponding to the peak of the curve representing the variation of the difference in absorbed power as a function of temperature.

[0131] It should be noted that the liquid fraction by weight of the pasty compound at room temperature is equal to the ratio between the enthalpy of fusion consumed at room temperature and the enthalpy of fusion of the pasty fat substance. The enthalpy of fusion The enthalpy of fusion of a pasty compound is the enthalpy consumed by the compound to change from a solid to a liquid state. A pasty compound is said to be in a solid state when its entire mass is in crystalline solid form. A pasty compound is said to be in a liquid state when its entire mass is in liquid form. The enthalpy of fusion of a pasty compound is the amount of energy required to change the pasty compound from a solid to a liquid state. It is expressed in J / g. The enthalpy of fusion of a pasty fat substance is equal to the area under the curve of the resulting thermogram.

[0132] Preferably, the paste-like compounds, also called hydrocarbon-based paste-like compounds, are selected from petroleum jelly; vegetable butters, such as, in particular, mango, shea, cupuacu, murumuru, cocoa, babassu or jojoba butters; fully or partially hydrogenated vegetable oils, such as, for example, hydrogenated soybean oil, hydrogenated coconut oil, hydrogenated rapeseed oil, mixtures of hydrogenated vegetable oils such as products bearing the INCI name hydrogenated vegetable oil, partially hydrogenated olive oil; esters of hydrogenated castor oil and C16-C22 fatty acids, bis-diglyceryl polyacyladipate-2; products bearing the INCI name hydrogenated coco-glycerides;dilinoleic alcohol and / or dilinoleic acid dimer esters, for example products bearing the following INCI names: bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate, phytosteryl / isostearyl / cetyl / stearyl / behenyl dimer dilinoleate, hydrogenated castor oil dimer dilinoleate, or mixtures thereof.
