Description

[Technical Field]

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

[0002] Mascara is generally prepared in two types of formulations: aqueous mascaras, which are in the form of emulsions containing water, e.g., known as cream mascaras, and anhydrous mascaras, which are in the form of wax-type dispersions in volatile organic solvents, e.g., known as waterproof mascaras.

[0003] Aqueous mascaras in the form of emulsions, such as O / W emulsions, can be easily removed with water, but the presence of water in emulsion mascaras makes it difficult to create and maintain a curling effect.

[0004] Anhydrous mascaras can create and maintain a stronger curl than water-based mascaras, but require special cleansing products, such as cleansing oils, to remove the cosmetic film created by anhydrous mascaras from the eyelashes.

[0005] Therefore, there remains a need for compositions for keratin fibers, particularly eyelashes, that have improved or enhanced removability while providing cosmetic benefits to the keratin fibers, such as curl-maintaining and volume-increasing benefits. [Prior art documents] [Patent documents]

[0107] Here, the term "saturated fatty alcohol" refers to an alcohol having a long aliphatic saturated carbon chain.

[0110] Furthermore, (b) oil is preferably selected from oils having a molecular weight of less than 600 g / mol.

[0111] Preferably, the (b) oil has a low molecular weight, such as less than 600 g / mol, and a short hydrocarbon chain (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.

[0118] (wax) The composition according to the present invention comprises (c) at least one wax. When two or more (c) waxes are used, they may be of the same or different types.

[0119] 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).

[0120] 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 above 45°C, for example, 50°C or higher, or even, for example, 55°C or higher. The melting point of the wax can be measured using a differential scanning calorimeter (DSC), for example, a calorimeter sold by Mettler under the name DSC30. The measurement protocol is as follows:

[0121] A 15 mg sample of the product placed in a crucible is subjected to a first temperature increase from 0°C to 120°C at a heating rate of 10°C / min, then a cooling rate of 10°C / min from 120°C to 0°C, and finally a second temperature increase 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.

[0122] 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.

[0123] 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:

[0124] The wax is melted at a temperature equal to the melting point of the wax + 20°C. The molten wax is poured into 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.

[0125] 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, hazelnut wax, Japan 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.

[0126] 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.

[0127] Among these oils, mention may be made, for example, of hydrogenated jojoba oil, isomerized jojoba oil (for example the trans-isomerized partially hydrogenated jojoba oil produced or sold by the company 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 the company Heterene under the name "Hest 2T-4S"), and bis(1,1,1-trimethylolpropane) tetrabehenate (sold by the company Heterene under the name "Hest 2T-4B").

[0128] For example, silicone waxes and fluorine waxes may also be used.

[0129] 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.

[0130] In one embodiment, the compositions 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 (e.g., 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.

[0131] 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 25 mm in diameter and 20 mm deep. 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 tack.

[0132] The texturometer spindle is moved at a speed of 0.5 mm / s and then penetrates the wax to a penetration depth of 2 mm. Once the spindle has penetrated the wax to a depth of 2 mm, the spindle is held for 1 second (corresponding to the relaxation time) and then the spindle is withdrawn at a speed of 0.5 mm / s.

[0133] 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 stiction corresponds to the integral of the curve of force as a function of time for the part of the curve corresponding to negative values ​​of force (extension). The stiction value is expressed in Ns.

[0134] 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 even further 0.1 MPa to 2.5 MPa.

[0135] Hardness is measured according to the protocol above.

[0136] Usable adhesive waxes include C 20 ~C 40 Alkyl(hydroxystearyloxy)stearates (wherein the alkyl group contains 20 to 40 carbon atoms) may be used alone or in mixtures, for example, those represented by the following formula:

[0137] [ka]

[0138] (wherein m is an integer ranging from 18 to 38), C 20 ~C 40 Alkyl 12-(12'-hydroxystearyloxy) stearate or a mixture of such compounds.

[0139] Such waxes are sold, for example, by Koster Keenan under the names "Kester Wax K 82 P®" and "Kester Wax K 80 P®".

[0140] The waxes mentioned above generally have a starting melting point of, for example, less than 45°C.

[0141] 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."

[0142] Particle size can be measured by various techniques, such as light scattering techniques (dynamic or static), Coulter counter methods, sedimentation velocity measurements (related to size by Stokes' law), and microscopic examination, which allow for the measurement of particle diameter and, in some cases, particle size distribution.

[0143] The particle size and particle size distribution of the compositions disclosed herein are measured, for example, by static light scattering using a conventional particle sizer (e.g., Malvern's MasterSizer 2000). The data are processed based on the Mie scattering theory. This theory is applicable 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.

[0144] As used herein, microcrystalline waxes are those having the following properties:

[0145]

number

[0146] (In the formula, V i is the effective diameter d i is the volume of the particle with This parameter D[4,3] can be found, for example, in the technical documentation of the particle sizer.

[0147] Measurements were performed at 25°C on dilute particle dispersions in the following manner: 1) diluting 100 times with water, 2) homogenizing the solution, 3) allowing the solution to stand for 18 hours, and 4) recovering the slightly white homogenous supernatant. It is obtained from microcrystalline wax by

[0148] 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.

[0149] Examples of microwaxes that may be used in the compositions disclosed herein include carnauba microwax (e.g., the product sold by Micro Powders under the name "MicroCare 350®"), synthetic microwax (e.g., the product sold by Micro Powders under the name "MicroEase 114S®"), microwaxes consisting of a mixture of carnauba wax and polyethylene wax (e.g., the products sold by Micro Powders under the names "Micro Care 300®" and "Micro Care 310®"), microwaxes consisting of a mixture of carnauba wax and synthetic wax (e.g., the product sold by Micro Powders under the name "Micro Powders 325®"), polyethylene microwax (e.g., the product sold by Micro Powders under the names "Micropoly 200®", "Micropoly 220®", "Micropoly 220L®" and "Micropoly 250S®"), and the like. Powders Co.], and polytetrafluoroethylene micropowder (e.g., products sold by Micro Powders Co. under the names "Microslip 519®" and "Microslip 519L®").

[0150] 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, the size of the wax particles being 1 μm or less.

[0151] 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.

[0152] For example, these wax microdispersions can be obtained by melting the wax in the presence of a surfactant and optionally some water, followed by gentle, gradual addition of hot water with 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.

[0153] The wax microdispersion can also be obtained by agitating a mixture of wax, surfactant and water using an agitation tool such as an ultrasonic high pressure homogenizer or a turbo mixer.

[0154] The particles of the wax microdispersion 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).

[0155] 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.

[0156] When the wax or mixture of waxes is present in the composition 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.

[0157] The wax particles can have a variety of shapes, for example, the wax particles can be spherical.
