Description

"COSMETIC PROCESSES, COSMETIC COMPOSITION AND KIT FOR COATING OF KERATIN MATERIALS"

Field of the Invention

The present invention relates to a process for coating keratin materials, in particular a non-therapeutic process for makeup or care of keratin materials, which comprises applying to these keratin materials at least two compounds A and B which are capable of reacting together, and at least one of the compounds is silicone.

Compositions according to the present invention may be compositions for the makeup or care of keratin materials, in particular the skin, lips, eyelashes, eyebrows or nails.

Background of the Invention

Each composition can be a loose or compact powder, a skin foundation, a makeup rouge, an eye shadow, a concealer, a blusher, a lipstick, a lip balm, lip gloss, lip gloss, lip pencil, eye pencil, rhyme, eyeliner, body makeup product or skin coloring product.

The care makeup can be an eyelash or lip care product, or a body and face skin care product, especially an anti-sun care product.

Lipstick and skin foundation compositions are commonly used to give the lips or skin, especially the face, an aesthetic appearance. Such make-up products generally contain fatty phases such as waxes and oils, pigments and / or fillers and optionally additives, for example cosmetic or dermatological active agents.

When applied to the skin, these compositions have the disadvantage that they are transferred, that is, become at least partially deposited and leave marks, on certain holders with which they may come in contact, and especially on certain holders such as cups, cups, cigarettes. , a garment or the skin. This results in negligible resistance to the applied film making it necessary to regularly renew the application of the base makeup for the skin or lipstick for the lips. In addition, the appearance of these unacceptable marks, especially on the collar of blouses, may make some women not wearing this kind of makeup.

"Transfer resistant" lip and skin makeup compositions are sought which have the advantage of forming a deposit which is not at least partially deposited on the supports with which they come into contact (cups, clothing, cigarettes or fabric) and have a good staying power.

To limit the transfer of cosmetic compositions, volatile oils are often used. These volatile oils present in large quantities make the make-up product, especially the lipsticks, uncomfortable for users: the make-up deposit gives a feeling of dryness and tightness.

In the case of eyelash-coating compositions or low water, anhydrous or water-soluble, or water-soluble solvents, called "waterproofing" are known in particular which are formulated as a dispersion of waxes in non-aqueous solvents which have good water and / or tallow resistance.

However, the make-up film obtained after application of these compositions is not sufficiently resistant to water, for example in dipping or showering, tears or sweat, or sebum. The rimei then tends to go out over time; Grains tend to wear out and unattractive marks appear around the eyes. Description of the Invention

The purpose of the present invention is to provide a novel route for formulating cosmetic compositions, in particular makeup compositions, which provide a film deposited on keratin materials which exhibit properties of good transfer resistance and staying power over time. in particular resistance to water and friction, and a comfortable deposit on the skin, lips, eyelashes or nails.

Dendrimers (from the Greek dendron = tree) are "branched", ie, branched polymeric molecules invented by DA Tomalia and his team in the early 1990s (Donald A. Tomalia et al., Angewandte Chemie1 Int. Engl. Ed. , Vol. 29, No. 2, pages 138 - 175). These are structures built around a central unit that is generally multipurpose. Surrounding this central unit are, in a perfectly determined structure, branched chain-lengthening units which thus give rise to symmetrical, monodisperse macromolecules having a well-defined chemical and stereochemical structure. Polyamidoamine-type dendrimers are sold, for example, under the Starbust® designation by Dendritech.

Hyperramified polymers are polycondensates, generally polyester, polyamide or polyethylene amine, obtained from multifunctional monomers, which have a arborescent structure similar to dendrimers but much less regular than theirs (see for example WO-A-93/17060 and WO 96/12754).

The viscous oil advantageously has a molecular mass of greater than or equal to 600 g / mol, for example greater than or equal to 700, or even 800, or even 900 g / mol.

The dynamic viscosity at 25 ° C of the viscous oil can be measured with a Mettler RM 180 rotary viscometer that takes into account the oil density in order to convert to cSt.

The Mettler 180 RM (Rheomat) can be equipped with different rotors depending on the order of viscosity magnitude to be measured. For a viscosity between 0.18 and 4.02 Pa.s, the apparatus is fitted with a rotor no. 3. For a viscosity between 1 and 24 Pa.s, the apparatus is equipped with a rotor no. 4. With a viscosity between 8 and 122 Pa.s, the machine is equipped with a rotor no. 5. The viscosity is read from the machine in deviation units (UD). Refer to the graphs supplied with the measuring apparatus below for the corresponding value in poises, and then to convert it to stokes.

The rotor speed of the rotor is 200 rpm.

From the moment the rotor is rotated at an established constant rotational speed (in this case 200 rpm), the viscosity value of the oil may vary over time. Measurements are taken at regular time intervals until they become constant. The viscosity value that has become constant over time is the value adopted as the value of the dynamic viscosity of the oil.

Such oil may be chosen from silicone oils or non-polar hydrocarbon oils having a viscosity greater than or equal to 200 cSt (2x10-4 m2 / s) mentioned above.

The wax usable in the present invention is generally a lipophilic compound which is solid at room temperature (25 ° C), with a reversible solid / liquid state change, and having a melting point greater than or equal to 30 ° C which may go to 120 ° C.

By bringing the wax to the liquid (melting) state, it can be made as miscible as the oils and form a microscopically homogeneous mixture, but by bringing the temperature of the mixture back to room temperature, the wax is recrystallized from the wax. mix oils. In particular, the waxes which are suitable for the present invention may have a melting point greater than approximately 45 ° C and in particular greater than 55 ° C.

The wax melting point can be measured with a differential scanning calorimeter (DSC) 1 for example, the calorimeter sold as DSC name 30 by Mettler.

The measurement protocol is as follows:

A 5 mg sample of wax placed in a crucible is subjected to a first temperature increase ranging from -20 ° C to 100 ° C at a heating rate of 10 ° C / minute, and then cooled to 120 ° C to 0 ° C at a cooling rate of 10 ° C / minute, and finally subjected to a second temperature increase ranging from -0 ° C to 120 ° C at a heating rate of 5 ° C / minute. During the second temperature rise, the change in the power difference absorbed by the empty crucible and the crucible containing the wax sample is measured as a function of temperature. The melting point of the compound is the temperature value which corresponds to the apex of the peak of the curve representing the change in power difference absorbed as a function of temperature.

The waxes that are used in the first and second compositions according to the present invention are chosen from waxes which are solid and rigid at room temperature, of animal, vegetable, mineral or synthetic origin, and mixtures thereof.

The waxes may also have a hardness ranging from 0.05 MPa to 30 MPas and preferably ranging from 6 MPa to 15 MPa.

Hardness is determined by measuring the compressive strength, measured at 20 ° C by means of a texturometer sold under the name TA-TX2Í by Rheo, with a 2mm diameter stainless steel cylinder that operates 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:

The wax is melted at a temperature equal to the wax melting point + 20 ° C. The molten wax is poured into a container 30 mm in diameter and 20 mm deep. The wax is recrystallized at room temperature (25 ° C) for 24 hours and then kept at 20 ° C for at least 1 hour before hardness measurement. The hardness value is the maximum compressive force measured divided by the surface area of the texturometer cylinder in contact with the wax.

In particular, hydrocarbon waxes may be used, for example beeswax, Ianoline wax or insect wax from China; rice wax, carnauba wax, candelilla wax, ouricuri wax, esparto wax, cork fiber wax, sugar cane wax, japan wax, and sumac wax; montana wax, microcrystalline waxes, paraffins and ozoquerite, polyethylene waxes, Fischer-Tropsch synthesis waxes and waxy copolymers, as well as their esters.

According to a particular embodiment, the first and second compositions according to the present invention may comprise at least one "sticky" wax, i.e. a wax having a tackiness greater than or equal to 0.7 N.s. and a hardness less than or equal to 3.5 MPa.

The sticky wax used may in particular have a tackiness of from 0.7 Ns to 30 Ns, particularly greater than or equal to 1 Ns, ranging in particular from 1 Ns to 20 Ns, in particular greater than or equal to 2 Ns, and varying. in particular from 2 Ns to 10 Ns and in particular from 2 Ns to 5 Ns

The stickiness of the wax is determined by measuring the change in force (compression force or elongation force) as a function of time at 25 ° C using a texturometer sold under the name TA-TX2® by Rheo with a rotor. of conical acrylic polymer that forms an angle of 45 °.

The measurement protocol is as follows;

The wax is melted at a temperature equal to the wax melting point + 10 ° C. The molten wax is poured into a container 25 mm in diameter and 20 mm deep. The wax is recrystallized at room temperature (25 ° C) for 24 hours until the wax surface is flat and smooth, and the wax is then stored for at least 1 hour at 20 ° C prior to stickiness measurement. The texturometer rotor is displaced at a speed of 0.5 mm / s and then penetrates the wax to a penetration depth of 2 mm. After the rotor has penetrated the wax to a depth of 2 mm, the rotor is held still for 1 second (which corresponds to the relaxation time) and is then removed at a speed of 0.5 mm / s.

During the relaxation time, the force (compression force) decreases sharply until it becomes zero, and then, during removal of the rotor, the force (stretching force) becomes negative and then rises to a value of 0. A stickiness corresponds to the integral of the curve of the curve that corresponds to the negative values of the force (elongation force). The stickiness value is expressed in N.s.

The sticky wax that can be used generally has a hardness of less than or equal to 3.5 MPa1 ranging in particular from 0.01 MPa to 1.5 MPa, and especially ranging from 0.05 MPa to 1 MPa or even 0.1. MPa to 2.5 MPa.

The wax (s) may be in the form of an aqueous wax microdispersion. The term "aqueous wax microdispersion" denotes an aqueous dispersion of wax particles wherein the particle size of said wax is less than or equal to approximately 1 μηι.

Wax microdispersions are stable dispersions of colloidal wax particles, and are described in particular in "Microemulsions Theory and Practice", L.M. Prince Ed., Academic Press (1977) pages 21-32.

In particular, such wax microdispersions may be obtained by melting the wax in the presence of a surfactant, and optionally a portion of water, followed by the gradual addition of hot water under stirring. Intermediate formation of a water-in-oil emulsion is observed, followed by phase inversion, with the final production of an oil-in-water microemulsion. After cooling, stable microdispersion of solid wax colloidal particles is obtained.

Wax microdispersions can also be obtained by stirring the wax, surfactant and water mixture with stirring media such as ultrasound, high pressure homogenizers, turbo mixers.

The wax microdispersion particles preferably have average sizes less than 1 μm (especially ranging from 0.02 μm to 0.99 μm) and in particular less than 0.5 μm (especially ranging from 0, 06 μm to 0.5 μm).

Hardness is measured at 20 ° C in the center of five samples. The rotor is fed into each sample at a pre-velocity of 1 mm / s and then at a measuring velocity of 0.1 mm / s. The penetration depth is 0.3 mm. The hardness value revealed is that of the maximum peak.

Such a liquid fraction at 23 ° C preferably represents between 15% and 85%, and more preferably between 40% and 85% by weight. The net weight fraction of the pasty compound at 23 ° C is equal to the ratio of melt heat consumed at 23 ° C to the melt heat of the pasty compound.

The melting heat of the pasty compound is the heat consumed by the compound to pass from a solid state to a liquid state. The pasty compound is said to be in the solid state when all of its mass is in solid crystalline form. The pasty compound is said to be in the liquid state when all its mass is in liquid form.

The melt heat of the pasty compound is equal to the area under the thermogram curve obtained by means of a differential scanning calorimeter (DSC), such as the calorimeter sold under the name MDSC 2920 by TA Instrument whose temperature increases by 5 or 10. ° C per minute according to ISO 11357-3: 1999. The melting heat of the pasty compound is the amount of energy required to make the compound change from solid to liquid state. It is expressed in J / g.

The heat of fusion consumed at 23 ° C is the amount of energy absorbed by the sample from solid state to 23 ° C, which consists of a liquid fraction and a solid fraction. The liquid fraction of the pasty compound, measured at 32 ° C, preferably represents from 30% to 100% by weight of the compound, preferably from 80% to 100% and more preferably from 90% to 100% by weight of the compound. When the liquid fraction of the pasty compound measured at 32 ° C is 100%, the melting point end temperature of the pasty compound is less than or equal to 32 ° C.

The liquid fraction of the pasty compound measured at 32 ° C is equal to the ratio of heat of melt heat consumed at 32 ° C to the melt heat of the pasty compound. The fusion heat consumed at 32 ° C is calculated in the same way as the fusion heat consumed at 23 ° C.

Pasty substances are generally hydrocarbon compounds, for example, Ianolines and their derivatives, or PDMSs.

The nature and quantity of solid substances depends on the desired mechanical properties and textures. By reference, the waxes represent from 0.1% to 70% by weight, more preferably from 1% to 40%, and most preferably from 5% to 30% by weight with respect to the total weight of each composition.

"Special effect pigments" means pigments which generally create a non-uniform colored color appearance (characterized by a certain hue, a certain vividness and a certain clarity) which changes as a function of the observation conditions (light , temperature, viewing angle, etc). They contrast in this respect with white or colored pigments that give a uniform opaque, semi-transparent or transparent uniform color.

There are two types of special effect pigments: those that have a low refractive index, such as fluorescent, photochromic or thermochromic pigments, and those that have a higher refractive index, such as pearlescent agents or shiny blades.

As special effect pigments, pearling pigments such as white pearled pigments such as titanium-coated mica or bismuth oxychloride, colored pearled pigments such as iron oxide titanium mica, titanium mica and in particular with ferric blue or chromium oxide, titanium mica and an organic pigment of the aforementioned type, as well as bismuth oxychloride-based pearlescent pigments.

Special effect pigments also include fluorescent pigments, whether they are daylight fluorescent substances or those producing ultraviolet fluorescence, phosphorescent pigments and photochromic pigments.

The pigment may also be a mineral pigment. By "mineral pigment" is meant any pigment that meets the definition of the Ullmann encyclopedia in the inorganic pigment chapter.

dispersant.

The dispersing agent serves to protect the dispersed particles against agglomeration or flocculation. Such dispersing agent may be a surfactant, an oligomer, a polymer or a mixture thereof, having one or more functionalities having a strong affinity for the surface of particles to be dispersed. In particular, they may physically or chemically attach to the surface of the pigments. These dispersants also have at least one compatible or soluble functional group in the continuous medium. In particular, esters of hydroxy-12 stearic acid and C8 to C20 fatty acid esters of polyols such as glycerol or diglycerol, such as poly (12-hydroxy stearic acid) stearate of molecular weight of approximately 750g / mol, such as that sold under the name of Solsperse 21 OOO by Avecia, polyglyceryl-2 dipolihydroxystearate (CTFA name) sold under the reference Dehymyls PGPH by Henkel, or polyhydroxysterearic acid such as which is sold under the reference Arlacel P100 by Uniqema, and mixtures thereof.

Mention may also be made of any fumed colloidal silica subjected to hydrophobic surface treatment with a particle size of less than 1 μm. In particular, it is possible to modify the silica surface by chemical reaction which generates a reduction in the number of silanol groups present on the silica surface. It is in particular possible to replace silanol groups with hydrophobic groups: a hydrophobic silica is then obtained. Hydrophobic groups can be:

trimethylsiloxyl groups, which are obtained in particular by treatment of fumed colloidal silica in the presence of hexamethyldisilazane.

Silicas treated in this way are called "Silica silylate" according to the CTFA (6th edition, 1995). They are for example marketed under the references Aerosil R812®, R200 by Degussa, Wacker HDX H2000 by Wacker and Cab-O-Sil TS-530® by Cabot;

- dimethylsilyloxy or polydimethylsiloxane groups, which are obtained in particular by treating fumed colloidal silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. The silicas thus treated are called "Silica dimethyl silylate" according to the CTFA (6th edition, 1995). They are, for example, marketed under the references Aerosil R972® and "Aerosil R974®" by Degussa1 Cab-O-Sil TS-610® and Cab-O-Sil TS-720® by Cabot.

Hydrophobic fumed colloidal silica has, in particular, a particle size which may be from nanometer to micrometer, ranging, for example, from approximately 5 to 200 nm.

It is also possible to use organic molecular non-polymeric gelling agents, also known as organogelifying agents, associated with a liquid grease phase (which may be the liquid grease phase of the composition according to the present invention), which are compounds whose molecules are capable of to establish physical interactions that lead to the self-aggregation of molecules with formation of a supramolecular 3D network that is responsible for gelation of the liquid grease phase.

The supramolecular network can result from the formation of a fibril network (caused by the stacking or aggregation of organogelifying molecules) that immobilizes the liquid grease phase molecules.

The ability to form such a fibril network, and therefore to gel, depends on the nature (or chemical class) of the organogelizing agent, the nature of the substituents carried by the molecules for a given chemical class, and the nature of the liquid grease phase.

Physical interactions are diverse in nature but exclude co-crystallization. These interactions are, in particular, self-complementary hydrogen interaction type interactions, π interactions between unsaturated cycles, dipolar bonds, coordination bonds with organometallic derivatives, and combinations thereof. In general, each molecule of an organogelizing agent can establish various types of physical interaction with the neighboring molecule. Thus, advantageously, the organogelizing agent molecules of the present invention may comprise at least one group capable of hydrogen bonding and most preferably at least two groups, at least one aromatic cycle, and even better at least two aromatic cycles. at least one or more ethylenically unsaturated bonds and / or at least one or more asymmetric carbons.

Part X:

<table> table see original document page 82 </column> </row> <table> Part Υ:

<table> table see original document page 83 </column> </row> <table>

The following compositions are prepared:

COMPOSITION 1:

<table> table see original document page 83 </column> </row> <table>

Composition 2:

<table> table see original document page 83 </column> </row> <table>

The first and second composition above are mixed together extemporaneously in a 50/50 ratio, and this mixture is then applied over the lips. After a few minutes of drying, a shiny, non-transferring film is observed on the lips.

(a) Film brightness is measured according to the following protocol:

A 150 μM layer of composition thickness is spread on a contrasting Byk Gardner reference card Prüfkarten, Art. 2853, pre-assembled on a 1 mm glass plate by means of an automatic spreader. Sheen), The layer covers at least the black background of the card. When the composition is solid, it is melted, if necessary, onto the cardboard after it has been spread to cover the black background. After the composition has been spread, the 60 ° gloss is measured on the black background by a microTri-Gloss reference Byk Gardner brillometer. Thus, four contrast cards are prepared to measure the average brightness of the composition, and the average of the four measurements is determined. For the measurement to be correct, the standard deviation must be less than or equal to 3%.

The formed film has an average brightness of 60 ° at 54. (b) The transfer of the film obtained by mixing the two compositions is evaluated as follows:

A support (40mm χ 70mm and 3mm thick rectangle) of polyethylene foam that is adhesive on one side, having a density of 33kg / m3 (sold under the Joint Technique Lyonnais Ind name RE40X0EP3) is pre -heated on a hot plate maintained at a temperature of 40 ° C so that the surface of the support is maintained at a temperature of 33 ± 1 ° C.

The mixture of the two compositions is applied to the total non-adhesive surface of the support by spreading with a thin brush to obtain a deposit of approximately 15 μιτι of the composition while the support is left on the hot plate, and the support is then Let it dry for 30 minutes.

After drying, the support is glued by its adhesive face to an anvil of 20 mm diameter and provided with a screw pitch. The holder / tank assembly is then cut by means of an 18 mm diameter stylus. The anvil is then screwed into a press (Stateco Manuel Imada SV-2 from Someco) equipped with a stress testing machine (Imada DPS-20 from Someco).

An 80 g / m2 white copier paper is placed in the press milk and the holder / hopper assembly is then pressed to the paper at a pressure of 2.5 kg for 30 seconds. After removing the holder / hopper assembly, a portion of the hopper is transferred to paper. The deposit color transferred to the paper is then measured with a Minolta CR300 colorimeter, and the color is characterized by the colorimetric parameters L *, a *, b *. The colorimetric parameters L * 0, a0 *, b0 * of the plain paper used are determined.

The color difference ΔΕ1 between the color of the transferred deposit in relation to the color of the smooth paple is then determined by the following ratio.

ΔΕ1 = -L0 *) 2 + (a * -a0 *) 2 + (b * -b0 *) 2

Separately, a total transfer reference is prepared by applying the composition directly to the paper, identical to that previously used, at room temperature (25 ° C), by spreading the composition by means of a thin brush to obtain a deposit of approximately 15 μm of the composition, and the deposit is allowed to dry for 30 minutes at room temperature (25 ° C). After drying the colorimetric parameters L * ', a *', b * 'of the deposit color placed on the paper, which correspond to the total deposit reference color, are measured directly.

The colorimetric parameters L * 0, a0 *, b0 * of the plain paper color used are determined.

The color difference ΔΕ2 between the total transfer reference color and the plain paper color is then determined by the following ratio:

ΔΕ2 = ^ (L * '-L0 *') 2 + (a * '-a0 *') 2 + (b * '-b0 *') 2

The composition transfer, expressed as a percentage, is equal to the ratio:

100 χ ΔΕ1 / ΔΕ2

The measurement is performed on 4 supports in succession and the transfer value corresponds to the average of the 4 measurements obtained with the 4 supports.

The film obtained from the mixture of compositions 1 and 2 has a transfer value of 0%. Example 2 Lipsticks for Lips
