Description

  The present invention relates to compositions suitable for keratin materials, preferably keratin fibers, more preferably eyelashes, such as mascaras, and methods and uses related to such compositions.

  Mascaras are generally in the form of two formulations, namely an emulsion containing water, for example, an aqueous mascara known as cream mascara, and a wax-type dispersion in a volatile organic solvent, such as water. It is prepared as anhydrous mascara known as proof mascara.

  Aqueous mascaras in the form of emulsions such as O / W emulsions can be easily removed with water. However, it is difficult for mascara in the form of an emulsion to provide and maintain a curl effect due to the presence of water in it.

  Anhydrous mascaras can provide and maintain a stronger curling effect than aqueous mascaras. However, a special cleansing product such as cleansing oil is required to remove the cosmetic film made by anhydrous mascara from the eyelashes.

  Thus, a composition for keratin fibers, especially eyelashes, which has improved or enhanced removability while imparting cosmetic effects such as curl-maintaining and volume-increasing effects to keratin fibers. Are still needed.

Is obtained. For example, the waxes that may be used herein may have a melting point above 45 ° C, such as 50 ° C or higher, even 55 ° C or higher. The melting point of the wax may be measured using a differential scanning calorimeter (DSC), such as the calorimeter sold by Mettler under the name DSC30. The measurement protocol is as follows.

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

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

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

  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 with a diameter of 30 mm and a depth of 20 mm. The wax is recrystallized at room temperature (25 ° C.) for 24 hours and then stored at 20 ° C. for at least 1 hour before taking hardness measurements. The hardness value is the maximum compressive strength measured divided by the area of the texturometer cylinder in contact with the wax.

  In one embodiment, the composition disclosed herein comprises at least one "tacky" wax, i.e., a wax having a tackiness of 0.7 Ns or greater and a hardness of 3.5 MPa or less. Can be included. By using an adhesive wax, it is possible to obtain, for example, a cosmetic composition which is easily applied to keratin fibers, adheres well to keratin fibers and gives a smooth, uniform and thick make-up. The adhesive wax used is, for example, 0.7 Ns to 30 N.s (1 N.s or more, such as 1 N.s to 20 N.s, further, 2 N.s or more, such as 2 N.s to 10 N.s, Furthermore, it may have a tackiness in the range of, for example, 2 N.s to 5 N.s. The stickiness of the wax is measured using a texturometer [sold by Rheo under the name "TA-TX2i®"] with a conical acrylic polymer spindle forming an angle of 45 °. It is determined by measuring the change (compression force or stretching force) as a function of time at 20 ° C. The measurement protocol is as follows.

  The wax is melted at a temperature equal to the melting point of the wax + 10 ° C. Pour molten wax into a container 25 mm in diameter and 20 mm deep. The wax is recrystallized at room temperature (25 ° C.) for 24 hours to smooth and smooth the surface of the wax, and then the wax is stored at 20 ° C. for at least 1 hour before measuring the tack.

  The texturometer spindle is moved at a speed of 0.5 mm / s and then penetrated through the wax to a penetration depth of 2 mm. Once the spindle has penetrated the wax to a depth of 2 mm, hold the spindle for 1 second (corresponding to the relaxation time) and then pull out the spindle at a speed of 0.5 mm / s.

  During the relaxation time, the force (compressive force) decreases significantly until it reaches zero, after which, during the withdrawal of the spindle, the force (stretching force) becomes negative and then rises again to the value zero. Adhesion corresponds to the integral of the force curve as a function of time for the part of the curve corresponding to the negative value of the force (stretching force). The value of tackiness is expressed in N.s.

  The tacky waxes that can be used generally have a hardness of, for example, 3.5 MPa or less, for example, 0.01 MPa to 3.5 MPa, even 0.05 MPa to 3 MPa, and even 0.1 MPa to 2.5 MPa.

  Particle size and particle size distribution of the compositions disclosed herein are measured by static light scattering using, for example, a conventional particle sizer (eg, MasterSizer 2000 by Malvern). The data are processed based on Mie scattering theory. This theory is compatible with isotropic particles and makes it possible to determine the "effective" particle size in the case of non-spherical particles. This theory is described, for example, in the publication Van de Hulst, H.C., "Light Scattering by Small Particles", Chapters 9 and 10, Wiley, New York, 1957.

  For example, these wax granule dispersions can be obtained by melting the wax in the presence of a surfactant and optionally a portion of water, and then slowly adding hot water with stirring. If intermediate formation of a water-in-oil emulsion is observed, then phase inversion is performed to produce the final oil-in-water microemulsion. Upon cooling, a stable fine-grained dispersion of solid wax colloidal particles is obtained.

  The wax fine particle dispersion can also be obtained by stirring a mixture of the wax, the surfactant and water using a stirring tool such as an ultrasonic high pressure homogenizer or a turbo mixer.

  These particles consist essentially of wax or a mixture of waxes. However, the particles may also contain small amounts of oily and / or pasty fat additives, surfactants and / or common fat-soluble additives / activators.
