Description

[Technical Field]

[0001] The present invention relates to compositions, such as mascaras, suitable for keratinous materials, preferably keratinous fibers, more preferably eyelashes, and methods relating to said compositions. [Background technology]

[0002] Mascara generally comes in two types of formulations: Water-based mascaras, such as emulsions containing water, known as cream mascaras, and Anhydrous mascaras, known for example as waterproof mascaras, in the form of wax dispersions in volatile organic solvents It is prepared as:

[0003] Water-based mascaras in emulsion form, such as O / W emulsions, can be easily removed with water. However, when it comes to sweat, the water in sweat can make it difficult for the cosmetic effects of water-based mascaras in emulsion form to last.

[0004] Waterless mascara can maintain its cosmetic effect longer against sweat and other factors than water-based mascara. However, it may not be easy to remove waterless mascara from the eyelashes. Also, sebum on the skin around the eyes, such as the eyelids, can cause smudging around the eyes.

[0005] Therefore, there is a need for compositions for keratin fibers, and in particular eyelashes, that can provide long-lasting cosmetic benefits without smudging, while at the same time being easily removable from the eyelashes. [Prior art documents] [Patent documents]

Therefore, the composition according to the present invention is preferably for use on eyelashes. In particular, the composition according to the present invention is useful as a mascara.

[0031] The composition according to the present invention, because it comprises a first and a second film-forming polymer, can also provide curl retention benefits to keratinous materials, preferably keratinous fibers, and more preferably eyelashes.

[0033] The compositions, methods and uses according to the present invention are described in more detail below.

[0034] [Composition] (First Lipid-Soluble Film-Forming Polymer) The composition according to the present invention comprises (a) at least one first lipophilic film-forming polymer. When two or more (a) first lipophilic film-forming polymers are used, they may be the same or different.

[0035] The term "film-forming polymer" means a polymer that is capable of forming, by itself or in the presence of an auxiliary film-forming agent, a continuous film that adheres to a support or substrate, particularly keratinous materials such as eyelashes. Film-forming polymers contribute to curl retention properties.

The film-forming polymer contributes to curl retention properties.

[0050] (b) The second lipophilic film-forming polymer is selected from polyvinyl alcohol and polyesters of fatty acids.

[0051] (b) The polyvinyl alcohol used in the polyester of polyvinyl alcohol and fatty acid as the second fat-soluble film-forming polymer is not particularly limited, and conventional polyvinyl alcohols can be used.

[0101] The term "fatty" in fatty alcohol means containing a relatively large number of carbon atoms. Thus, alcohols having 4 or more, preferably 6 or more, more preferably 12 or more carbon atoms are included within the scope of fatty alcohol. Fatty alcohols may be saturated or unsaturated. Fatty alcohols may be linear or branched.

[0102] The fatty alcohol may have the structure R—OH, where R is selected from saturated and unsaturated, linear and branched groups containing from 4 to 40 carbon atoms, preferably from 6 to 30 carbon atoms, and more preferably from 12 to 20 carbon atoms.

[0106] Here, the term "saturated fatty alcohol" refers to an alcohol having a long aliphatic saturated carbon chain. The saturated fatty alcohol may be any linear or branched saturated C6-C 30 Preferably, the alcohol is selected from linear or branched saturated C6-C6 fatty alcohols. 30 Among fatty alcohols, linear or branched saturated C 12 ~C 20Fatty alcohols are preferably used. Any linear or branched saturated C 16 ~C 20 Fatty alcohols are more preferably used. 16 ~C 20 Fatty alcohols may even more preferably be used.

[0108] According to at least one embodiment, the fatty alcohols used in the compositions according to the invention are preferably chosen from cetyl alcohol, octyldodecanol, hexyldecanol, and mixtures thereof.

[0109] It is also preferred that the (c) oil is selected from oils having a molecular weight of less than 600 g / mol.

[0110] Preferably, the (c) oil has a low molecular weight, such as less than 600 g / mol, and is a short chain hydrocarbon (C1 to C 12 ester oils (e.g., isopropyl lauroyl sarcosinate, isopropyl myristate, isopropyl palmitate, isononyl isononanoate, and ethylhexyl palmitate), silicone oils (e.g., volatile silicones such as cyclohexasiloxane), hydrocarbon oils (e.g., isododecane, isohexadecane, and squalane), branched and / or unsaturated fatty alcohols (C ) such as octyldodecanol and oleyl alcohol; 12 ~C 30 ) type oils, as well as ether oils such as dicaprylyl ether.

[0111] (c) The oil is preferably selected from volatile oils, non-volatile oils, and mixtures thereof.

[0112] (c) The oil is preferably selected from hydrocarbon oils.

[0113] Even more preferably, the (c) oil is selected from volatile and non-volatile hydrocarbon oils such as isododecane, paraffin, and hydrogenated polyisobutene.

[0114] The amount of (c) oil in the composition according to the present invention may be 20% by weight or more, preferably 30% by weight or more, more preferably 40% by weight or more, relative to the total weight of the composition.

[0115] The amount of (c) oil in the composition according to the present invention may be 80% by weight or less, preferably 70% by weight or less, more preferably 60% by weight or less, based on the total weight of the composition.

[0116] The amount of (c) oil in the composition according to the present invention may be from 20% to 80% by weight, preferably from 30% to 70% by weight, more preferably from 40% to 60% by weight, relative to the total weight of the composition.

[0117] (wax) The composition according to the present invention comprises at least one wax (d). When two or more waxes (d) are used, they may be the same or different.

[0118] Waxes as used herein are lipophilic compounds that are generally solid at room temperature (25°C), capable of reversible change between solid and liquid states, and have a melting point of 30°C or higher (sometimes up to 120°C).

[0119] By bringing the wax into a liquid state (melting), it can be mixed with the oil to form a microscopically uniform mixture, but when the mixture is cooled to room temperature, the wax recrystallizes in the oil of the mixture. For example, the wax that can be used herein can have a melting point of more than 45°C, for example, 50°C or higher, or even 55°C or higher. The melting point of the wax can be measured using a differential scanning calorimeter (DSC), for example, the calorimeter sold by Mettler under the name DSC30. The measurement protocol is as follows:

[0120] A 15 mg sample of the product placed in a crucible is subjected to a first temperature increase ranging from 0°C to 120°C at a heating rate of 10°C / min, then cooled from 120°C to 0°C at a cooling rate of 10°C / min, and finally subjected to a second temperature increase ranging from 0°C to 120°C at a heating rate of 5°C / min. The change in the difference between the power absorbed by the empty crucible and the power absorbed by the crucible containing the product sample during the second temperature increase is measured as a function of temperature. The melting point of the compound is the temperature value corresponding to the apex of the peak of the curve representing the change in the difference in absorbed power as a function of temperature.

[0121] The waxes that may be used in the compositions disclosed herein are solid and rigid at room temperature and are selected from waxes of animal, vegetable, mineral or synthetic origin, and mixtures thereof.

[0122] The wax may also have a hardness, for example, in the range of 0.05 MPa to 30 MPa (e.g., 6 MPa to 15 MPa). The hardness is determined by measuring the compressive strength, which is measured at 20°C using a texturometer (sold by Rheo under the name TA-TX2i) equipped with a stainless steel cylinder with a diameter of 2 mm, which is moved at a measuring speed of 0.1 mm / s and penetrates the wax to a penetration depth of 0.3 mm. The measurement protocol is as follows:

[0123] The wax is melted at a temperature equal to the melting point of the wax + 20°C. The molten wax is cast in a container 30 mm in diameter and 20 mm deep. The wax is allowed to recrystallize at room temperature (25°C) for 24 hours and then stored at 20°C for at least 1 hour before the hardness measurement is carried out. The hardness value is the maximum compressive strength measured divided by the area of ​​the texturometer cylinder in contact with the wax.

[0124] Hydrocarbon waxes such as beeswax, lanolin wax, privet wax, rice bran wax, carnauba wax, candelilla wax, ouricle wax, espartograss wax, cork fiber wax, sugarcane wax, Japan wax, sumach wax, montan wax, microcrystalline wax, paraffin and ozokerite, polyethylene wax, waxes obtained by Fischer-Tropsch synthesis, and waxy copolymers and esters thereof may be used.

[0125] Also, for example, linear or branched C8 to C 32 Waxes obtained by catalytic hydrogenation of animal or vegetable oils containing fatty chains may also be used.

[0126] Among these oils, mention may be made, for example, of hydrogenated jojoba oil, isomerized jojoba oil (e.g., the trans-isomerized partially hydrogenated jojoba oil manufactured or sold by Desert Whale under the trade name "Iso-Jojoba-50®"), hydrogenated sunflower oil, hydrogenated castor oil, hydrogenated coconut oil, hydrogenated lanolin oil, bis(1,1,1-trimethylolpropane) tetrastearate (sold by Heterene under the name "Hest 2T-4S"), and bis(1,1,1-trimethylolpropane) tetrabehenate (sold by Heterene under the name "Hest 2T-4B").

[0127] For example, silicone waxes and fluorine waxes may also be used.

[0128] Furthermore, waxes obtained by hydrogenation of olive oil esterified with stearyl alcohol (sold under the name "Phytowax Olive 18 L 57") or waxes obtained by hydrogenation of castor oil esterified with cetyl alcohol (sold under the names "Phytowax Ricin 16L64 and 22L73" by the company Sophim) can also be used. Such waxes are described in French patent application FR-A-2792190.

[0129] In one embodiment, the composition disclosed herein may comprise at least one "tacky" wax, i.e., a wax having a tack of 0.7 Ns or more and a hardness of 3.5 MPa or less. The use of a tacky wax can, for example, provide a cosmetic composition that is easily applied to keratin fibers, adheres well to the keratin fibers, and provides a smooth, uniform, and rich makeup. The tacky wax used may have a tack ranging from 0.7 Ns to 30 Ns (such as 1 Ns or more, e.g., 1 Ns to 20 Ns, or even 2 Ns or more, e.g., 2 Ns to 10 Ns, or even 2 Ns to 5 Ns). The tackiness of the wax is determined by measuring the change in force (compression or expansion) as a function of time at 20°C using a texturometer (sold by Rheo under the name "TA-TX2i®") equipped with a conical acrylic polymer spindle forming a 45° angle. The measurement protocol is as follows.

[0130] The wax is melted at a temperature equal to the melting point of the wax + 10°C. The molten wax is poured into a container with a diameter of 25 mm and a depth of 20 mm. The wax is allowed to recrystallize at room temperature (25°C) for 24 hours to make the surface of the wax flat and smooth, and then the wax is stored at 20°C for at least 1 hour before measuring the adhesive strength.

[0131] The texturometer spindle is moved at a speed of 0.5 mm / s and then penetrated into the wax to a depth of 2 mm. Once the spindle has penetrated the wax to a depth of 2 mm, the spindle is held for a further 1 second (corresponding to the relaxation time) and then withdrawn at a speed of 0.5 mm / s.

[0132] During the relaxation time, the force (compression) decreases significantly until it reaches zero, after which, while withdrawing the spindle, the force (extension) becomes negative and then rises again to a value of zero. The adhesion force corresponds to the integral of the curve of the force as a function of time for the part of the curve corresponding to the negative values ​​of the force (extension). The value of the adhesion force is expressed in Ns.

[0133] The adhesive wax that can be used generally has a hardness of, for example, 3.5 MPa or less, for example, a hardness of 0.01 MPa to 3.5 MPa, further 0.05 MPa to 3 MPa, and further 0.1 MPa to 2.5 MPa.

[0134] Hardness is measured according to the protocol above.

[0135] The tacky waxes that can be used include C alone or as a mixture. 20 ~C 40 Alkyl(hydroxystearyloxy)stearates (wherein the alkyl group contains 20 to 40 carbon atoms), such as those represented by the following formula:

[0136] [ka]

[0137] (wherein m is an integer ranging from 18 to 38) C 20 ~C 40 Alkyl 12-(12'-hydroxystearyloxy) stearates or mixtures of these compounds are included.

[0138] Such waxes are sold, for example, by Koster Keenan under the names "Kester Wax K 82 P®" and "Kester Wax K 80 P®".

[0139] The waxes mentioned above generally have a starting melting point of, for example, less than 45°C.

[0140] As disclosed herein, waxes supplied in the form of small particles having sizes, expressed as an average "effective" volume diameter D[4,3], ranging from, for example, 0.5 to 30 micrometers, such as 1 to 20 micrometers, or even 5 to 10 micrometers, can also be used, and this form of wax is referred to herein as "microwax."

[0141] Particle size can be measured by a variety of techniques, including light scattering techniques (dynamic or static), Coulter counters, sedimentation velocity measurements (related to size by Stoke's law), and microscopy. These techniques measure particle diameter, and some techniques measure particle size distribution.

[0142] The size and size distribution of particles in the compositions disclosed herein are measured by static light scattering, for example, using a commercially available particle sizer (e.g., Malvern's MasterSizer 2000). The data are processed based on the Mie scattering theory, which applies to isotropic particles and allows the determination of the "effective" particle size for non-spherical particles. This theory is described, for example, in the publication Van de Hulst, HC, "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

[0143] As used herein, microwaxes are characterized by the meaning of an "effective" diameter by volume D[4,3], defined in the following manner:

[0144]

number

[0145] Vi is the effective diameter d i This parameter D[4,3] is given, for example, in the technical documentation of the granulometer.

[0146] Measurements are carried out at 25°C on dilute particle dispersions obtained from microwax in the following manner: 1) dilute 100 times with water, 2) homogenize the solution, 3) let the solution stand for 18 hours, and 4) collect the cloudy, homogenous supernatant.

[0147] The "effective" diameter is obtained by taking the refractive index for water to be 1.33 and the average refractive index for the particles to be 1.42.

[0148] Among the microwaxes that can be used in the compositions disclosed herein are, for example, carnauba microwaxes (e.g., the product sold by Micro Powders under the name "MicroCare 350®"), synthetic microwaxes (e.g., the product sold by Micro Powders under the name "MicroEase 114S®"), microwaxes comprising a mixture of carnauba wax and polyethylene waxes (e.g., the products sold by Micro Powders under the names "Micro Care 300®" and "Micro Care 310®"), microwaxes comprising a mixture of carnauba wax and synthetic waxes (e.g., the product sold by Micro Powders under the name "Micro Powders 325®"), polyethylene microwaxes (e.g., the products sold by Micro Powders under the names "Micropoly 200®", "Micropoly 220®", "Micropoly 220L®" and "Micropoly 250S®"), and polytetrafluoroethylene fine powders (e.g., "Microslip®"). 519® and Microslip 519L®, sold by the company Micro Powders, may be mentioned.

[0149] The wax (including tacky wax) may be present in the form of an aqueous microdispersion of wax. The term "aqueous microdispersion of wax" means an aqueous dispersion of wax particles in which the wax particles have a size of 1 μm or less.

[0150] Wax microdispersions are stable dispersions of colloidal wax particles and are described, for example, in "Microemulsions Theory and Practice", LM Prince Ed., Academic Press (1977) pp. 21-32.

[0151] For example, these wax microdispersions can be obtained by melting wax in the presence of a surfactant and, optionally, some water, followed by the gradual addition of hot water while stirring. Once the intermediate formation of a water-in-oil emulsion is observed, a phase inversion is then carried out to produce the final oil-in-water microemulsion. Upon cooling, a stable microdispersion of solid wax colloidal particles is obtained.

[0152] The wax microdispersion can also be obtained by stirring a mixture of wax, surfactant and water using a stirring tool such as an ultrasonic high-pressure homogenizer or a turbomixer.

[0153] The particles of the wax microparticle dispersion have, for example, an average size of less than 1 μm (such as in the range of 0.02 μm to 0.99 μm), for example, 0.5 μm or less (such as in the range of 0.06 μm to 0.5 μm).

[0154] These particles consist essentially of a wax or a mixture of waxes, but may also contain small amounts of oily and / or pasty fatty additives, surfactants and / or general fat-soluble additives / active agents.

[0155] When the wax or mixture of waxes is present in the compositions disclosed herein in the form of an aqueous dispersion of particles, the size of the particles, i.e., the average "effective" volume diameter D[4,3] as defined above, may be, for example, 1 μm or less, such as 0.75 μm or less.

[0156] The wax particles may have a variety of shapes, for example, the wax particles may be spherical.

[0162] Again, the term "film-forming polymer" means a polymer that is capable of forming, by itself or in the presence of an auxiliary film-forming agent, a continuous film that adheres to a support or substrate, particularly keratinous materials such as eyelashes. The film-forming polymer contributes to curl retention properties.

[0163] (e) The third lipophilic film-forming polymer is selected from vinylpyrrolidone (VP) copolymers.

[0169] (fiber) In some embodiments, the composition according to the present invention may further comprise at least one fiber to improve the elongation effect. Fibers useful in the present invention may be selected from rigid or non-rigid fibers and may be natural or synthetic. Natural fibers include, but are not limited to, cotton, silk, wool, and other keratin fibers. Synthetic fibers include, but are not limited to, polyester, rayon, nylon, and other polyamide fibers.
