Disclosed herein is a cosmetic composition comprising at least one sebum-absorbing powder having a sebum uptake, at least one second powder having a critical surface energy of less than or equal to 24 mN/m, and a liquid binder phase comprising at least one non-volatile oil.

Description

[0002] Disclosed herein is a cosmetic composition comprising a mixture of powders. Also disclosed herein is a process for making up and/or caring for keratin materials, such as human skin, lips, nails, and hair, comprising applying the composition to the keratin materials.

[0003] The composition disclosed herein may be a makeup and/or care composition for keratin materials, for example a skin makeup composition, such as a foundation, an eyeshadow, a makeup rouge, a concealer product, a face and body powder, and a body makeup product.

[0004] Makeup powders generally comprise, firstly, a pulverulent phase that may comprise pigments and fillers, and, secondly, a fatty phase that acts as a binder comprising fatty substances (i.e., a binder phase), intended to give the finished product a certain amount of density, to give the makeup product softness and an emollient nature, and to promote its adhesion to the skin.

[0005] After makeup is applied to the skin, the sebum excreted by the skin over time may modify the cosmetic properties of the makeup. For example, sebum may not promote the adhesion of the makeup to the skin. The makeup may have a tendency to transfer onto surfaces or fabrics placed in contact with the made-up skin, resulting in a loss of makeup remaining on the skin. In addition, the sebum-impregnated makeup may have a tendency to migrate more easily into the folds or wrinkles of the face, making the makeup deposit non-uniform. Furthermore, sebum may make the makeup more sensitive to rubbing, for example to rubbing against fabrics or the fingers, causing removal of the makeup over time. The poor staying power of the makeup in the course of the day may make it necessary for the user to freshen the application of the makeup in order to maintain a uniform makeup effect.

[0006] Moreover, sebum has a tendency to modify the color of the makeup deposited on the skin: for example, the color may become darker. This change in color may go against the desired colored aesthetic effect, since the visual appearance of the makeup no longer corresponds to the initial color of the composition chosen. The makeup may also become shinier; however, this shiny appearance is not desired for a foundation, since consumers prefer a matte makeup that maintains this matte effect throughout the day.

[0007] It is known practice from WO 97/04737 to use sebum-absorbing powders as a mixture with fillers and/or pigments in makeup powder compositions. However, the fillers and pigments may also become impregnated with sebum, and the adsorption of sebum does not take place selectively by the sebum-absorbing powders. The drawbacks caused by the excretion of sebum over time, for example the change in color and the shiny appearance of the makeup, thus remain for these compositions.

[0008] One aim of the present inventors was thus to provide a makeup composition that can efficiently absorb sebum and thus give a makeup with good cosmetic properties over time, such as good resistance to rubbing, transfer-resistant properties, good homogeneity, maintenance of the initial color of the makeup, and absence -of sheen (i.e., resistance of the matte effect).

[0009] The inventors have discovered that such a composition may be obtained by using at least one sebum-absorbing powder combined with at least one second powder having a specified critical surface energy. This powder with a specified critical surface energy may not become impregnated with sebum when the makeup is deposited on the skin, and thus may prevent sebum excreted over time from modifying the cosmetic properties of the makeup.

[0010] For example, one embodiment disclosed herein is a cosmetic composition comprising a pulverulent phase comprising at least one sebum-absorbing powder having the ability to uptake sebum, at least one second powder having a critical surface energy of less than or equal to 24 mN/m, and a liquid binder phase.

[0011] Another embodiment is a non-therapeutic cosmetic process for making up and/or caring for keratin materials, comprising applying to the keratin materials a composition as defined above. The keratin materials may, for example, be human skin.

[0012] Yet another embodiment is the use of a composition as defined above to obtain a non-shiny, uniform, transfer-resistant, and/or rub-resistant makeup result on the skin and/or a makeup result that shows maintenance of the initial color.

[0013] A further embodiment disclosed herein is the use of at least one sebum-absorbing powder having the ability to uptake sebum, and of at least one second powder having a critical surface energy of less than or equal to 24 mN/m, in a cosmetic composition to obtain a non-shiny, uniform, transfer-resistant, and/or rub-resistant makeup result on the skin and/or a makeup result that shows maintenance of the initial color.

[0014] As disclosed above, the composition disclosed herein comprises at least one sebum-absorbing powder having the ability to uptake sebum. In certain embodiments, the sebum uptake of the powder is greater than or equal to 1 ml/g, such as a sebum uptake ranging from 1 ml/g to 20 ml/g, or ranging from 1 ml/g to 15 ml/g. For example, the at least one sebum-absorbing powder may have a sebum uptake of greater than or equal to 1.5 ml/g, such as a sebum uptake ranging from 1.5 ml/g to 20 ml/g, or ranging from 1.5 ml/g to 15 ml/g. As a further example, the sebum uptake may be greater than or equal to 2 ml/g, such as a sebum uptake ranging from 2 ml/g to 20 ml/g, or ranging from 2 ml/g to 15 ml/g.

[0015] As used herein, the term “sebum-absorbing powder” means a powder capable of absorbing and/or adsorbing sebum.

[0016] The sebum uptake corresponds to the amount of sebum absorbed and/or adsorbed by the powder. It may be measured according to the Wet Point method described below.

[0017] In certain embodiments, the at least one sebum-absorbing powder may have a BET specific surface area of greater than or equal to 300 m2/g, such as greater than 500 m2/g, for example greater than 600 m2/g, and for example less than 1500 m2/g.

[0018] The “BET specific surface area” is determined according to the BET (Brunauer-Emmet-Teller) method described in “The Journal of the American Chemical Society”, Vol. 60, page 309, February 1938, and corresponding to ISO international standard 5794/1 (appendix D). The BET specific surface area corresponds to the total specific surface area (thus including micropores) of the powder.

[0055] The viscosity is measured at 25° C.±0.5° C. using a Haake RS75 controlled-stress rheometer from the company Thermo Rheo, equipped with a spindle of cone/plate geometry with a diameter ranging from 2 cm to 6 cm and an angle ranging from 1° to 2°, the choice of the spindle depending on the viscosity to be measured (i.e., the more fluid the oil, the greater the diameter of the chosen cone and the smaller the angle). The measurement is performed by applying on the oil sample a logarithmic shear stress gradient τ ranging from 0.2 Pa to 1000 Pa for a duration of 20 minutes. The rheogram representing the change in viscosity as a function of the change in shear ε′ is then plotted. The rheogram shows a plateau at low shear rate values (known as a Newtonian plateau). This plateau corresponds to a stable viscosity value, which is the viscosity of the oil thus determined.

[0108] Needless to say, a person skilled in the art will take care to select this or these optional additional compound(s), and/or the amount thereof, such that the advantageous properties of the composition disclosed herein are not, or are not substantially, adversely affected by the envisaged addition.

[0109] The composition disclosed herein may be in a form chosen from compact powders, pressed powders, cast powders, and free powders. It may also be in a form chosen from gels, water-in-oil emulsions, oil-in-water emulsions, multiple emulsions, milks, and pastes.

[0110] The invention is illustrated in greater detail by the examples described below. Other than in the examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained herein. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.

[0111] Notwithstanding that the numerical ranges and parameters setting forth the broad scope are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contain certain errors necessarily resulting from the standard deviation found in their-respective testing measurements.

[0112] Method for Measuring the Sebum Uptake of a Powder:

[0113] The sebum uptake of a powder may be measured according to the method for determining the oil uptake of a powder described in standard NF T 30-022. It corresponds to the amount of sebum adsorbed onto the available surface of the powder by measuring the Wet Point.

[0114] An amount m (in grams) of powder, ranging from 0.5 g to 5 g (the amount, depends on the density of the powder), is placed on a glass plate, followed by dropwise addition of artificial sebum having the following composition:

triolein              29%
oleic acid            28.5%
oleyl oleate          18.5%
squalene              14%
cholesterol           7%
cholesteryl palmitate 3%

[0115] After adding 4 to 5 drops of artificial sebum, the artificial sebum is incorporated into the powder using a spatula and the addition of artificial sebum is continued until conglomerates of artificial sebum and of powder are formed. At this point, the artificial sebum is added one drop at a time and the mixture is then triturated with the spatula. The addition of artificial sebum is stopped when a smooth, firm paste is obtained. This paste should be able to be spread out on the glass plate without cracking or forming lumps. The volume Vs (expressed in ml) of artificial sebum used is then noted.

[0116] The sebum uptake corresponds to the ratio Vs/m.

[0117] Method for Measuring the Critical Surface Energy of a Powder:

[0118] The powder is compacted using a pelletizer, such as the Manual Hydraulic Press manufactured by Perkin-Elmer (used to prepare samples analysed by infrared spectroscopy). The compacting pressure is 10 tonnes. The pellet of compacted powder has a diameter of about 10 mm and a thickness of about 1 mm.

[0119] The pellets of compacted powder are placed on the sample holder of a contact-angle tensiometer such as the tensiometer DAT 1100 sold by the company Fibro (Sweden).

[0120] The contact angle measurements are performed at 27±1° C. with the following three solvents: water, diiodomethane, and formamide.

[0121] For each of the solvents, one drop of solvent, with a volume ranging from 2 to 10 microliters, is placed on the powder pellet. The optical system and image analysis system of the tensiometer allow the change over time of the spreading of the drop to be monitored. The contact angle of the liquid on the compacted powder corresponds to the angle between the powder/liquid contact surface and the tangent to the drop passing through the point at which the drop, the air and the surface meet.

[0122] The contact angle-value used for the determination of the critical surface energy is the mean of the contact angles measured on 5 to 10 powder pellets, the angle values being taken after a contact time between the drop of solvent/powder pellet equal to 1 second.

[0123] For the determination of the critical surface energy, the change of the cosine of the contact angle as a function of the surface tension of the associated solvent is plotted on a graph, for the 3 test solvents.

[0124] The critical surface energy of the powder then corresponds to the surface tension such that the cosine of the contact angle is equal to 1 when the change in contact angle as a function of the surface tension is linearly extrapolated.
