Abstract

The invention relates to a cosmetic method for making up and/or caring for keratinous substances, in particular the skin, comprising the application, to said keratinous substances, of a cosmetic composition comprising a siloxane resin and an inorganic filler. The invention relates in particular to compositions for caring for or making up said keratinous substances.

Description

The invention relates to a cosmetic method for making up and/or caring for keratinous substances, in particular the skin, comprising the application to said keratinous substances of a cosmetic composition comprising a siloxane resin and an inorganic filler. The invention relates in particular to compositions for caring for or making up said keratinous substances.
It is known to use makeup products in order to contribute color and mattness to the skin. The makeup resulting from these makeup products is expected to last all day.
A makeup product must also be comfortable. Comfortable is understood to mean a product which glides over the skin, without a rubbing feeling, when the product is applied to the skin, but also a product which confers a soft touch on said skin.
It is known to a person skilled in the art to confer comfort properties on a makeup product, such as is described above, by formulating these products with fillers.
It is also known to a person skilled in the art to confer properties of hold of a makeup by formulating these products with silicone resins, polyacrylates or latexes, which have, however, a tendency to provide a feeling of discomfort after application, with a tacky feel.
The aim of the present invention is thus to provide a makeup method which makes it possible to obtain satisfactory properties of hold of the makeup while at the same time retaining the comfort during and after application.
This aim and others are achieved by the present invention which describes in particular a cosmetic method for making up and/or caring for keratinous substances, comprising the application, to said keratinous substances, in particular to the skin, of a composition comprising, in a physiologically acceptable medium:

- i) a siloxane resin comprising the units:
  - (R¹ ₃SiO_1/2)_a
  - (ii) (R² ₂SiO_2/2)_b
  - (iii) (R³SiO_3/2)_cand
  - (iv) (SiO_4/2)_d
    with
- R¹, R²and R³independently representing an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group or an amino group,
- a being between 0.05 and 0.5,
- b being between zero and 0.3,
- c being greater than zero,
- d being between 0.05 and 0.6,

a+b+c+d=1,
provided that more than 40 mol % of the R³groups of the siloxane resin are propyl groups, and

- ii) at least one inorganic filler.

The combination used according to the invention makes it possible to obtain a soft finish on the skin and cosmetic properties which are stable over time, in particular throughout the day. The product also glides over the skin, during application, without a rubbing feeling and confers a soft touch on said skin.
The composition according to the invention can be provided in various forms, in particular in the form of powders (loose or compact), of an anhydrous dispersion, of a water/oil, water/wax, oil/water, multiple (such as a water/oil/water or oil/water/oil) or wax/water emulsion or in the form of a gel. Preferably, the composition according to the invention is provided in the form of powders (loose or compact), of anhydrous dispersions or of emulsions, preferably an inverse emulsion (i.e., water/oil emulsion).
The composition according to the invention is intended in particular for making up and/or caring for the skin.

In the present invention, “carbinol group” is understood to mean any group comprising at least one hydroxyl radical bonded to a carbon (COH). The carbinol groups can thus comprise more than one COH radical, such as, for example:
If the carbinol group is devoid of aryl groups, it comprises at least 3 carbon atoms. If the carbinol group comprises at least one aryl group, it comprises at least 6 carbon atoms.
Mention may be made, as examples of carbinol group devoid of aryl groups comprising at least 3 carbon atoms, of the groups of formula R⁴OH in which R⁴represents a divalent hydrocarbon radical comprising at least 3 carbon atoms or a divalent hydrocarbonoxy radical comprising at least 3 carbon atoms.

The D, T or Q siloxane units of the MQ-propyl T resin according to the invention can comprise hydroxyl (—OH) groups and/or alkoxy groups. Such siloxane units comprising hydroxyl and/or alkoxy groups are commonly present in siloxane resins having the general formula R_nSiO_(4-n)/2.
These hydroxyl groups typically result from the reaction of a hydrolyzable group on the siloxane unit with water; the alkoxy groups result from an incomplete hydrolysis when alkoxysilane precursors are used or result from the exchange of alcohol with hydrolyzable groups.
Preferably, the total amount by weight of —OH groups present in the MQ-propyl T resin is approximately 3%, preferably 2%, preferably 1.5%. Preferably, the total amount by weight of alkoxy groups present in the MQ-propyl T resin is less than or equal to 20% by weight, preferably less than or equal to 10% by weight.

The siloxane resins which can be used according to the invention can be obtained by a process comprising the reaction between:

- A) an MQ resin comprising at least 80 mol % of (R¹ ₃SiO_1/2)_aand (SiO_4/2)_dunits,
  - R¹representing an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group or an amino group,
    - a and d being greater than zero,
    - the ratio aid being between 0.5 and 1.5;
      and
- B) a propyl T resin comprising at least 80 mol % of (R³SiO_3/2)_cunits,
  - R³representing an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group or an amino group,
    - c being greater than zero,
  - provided that at least 40 mol % of the R³groups are propyl groups,
    where the A/B ratio by weight is between 95:5 and 15:85.

The component A) is an MQ resin comprising at least 80 mol % of (R¹ ₃SiO_1/2)_aand (SiO_4/2)_dunits, where R¹is as defined above, i.e. represents an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group or an amino group, a and d are greater than zero and the ratio aid is between 0.5 and 1.5.
The MQ resins which can be used as component A) and their method of preparation are known from the prior art. For example, U.S. Pat. No. 2,814,601, belonging to Currie and al., dated Nov. 26, 1957 describes a process for manufacturing MQ resins by conversion of a water-soluble silicate into a silicic acid monomer or a silicic acid oligomer by using an acid. Once the appropriate polymerization has been carried out, trimethylchlorosilane ends are introduced in order to obtain the MQ resin. Another process of preparation of MQ resins is described in U.S. Pat. No. 2,857,356, belonging to Goodwin, dated Oct. 21, 1958. Goodwin describes a process for the manufacture of an MQ resin by cohydrolysis of a mixture of an alkyl silicate and of a trialkylsilane organopolysiloxane which can be hydrolyzed with water. The MQ resins suitable as component A) in the present invention can comprise D and T units, provided that at least 80 mol %, indeed even 90 mol %, of the total siloxane units are M and Q units. The MQ resins can also comprise hydroxyl groups. The MQ resins can thus comprise hydroxyl groups in a total amount by weight of between 2 and 10%, preferably between 2 and 5%. The MQ resins can also comprise additional ends, residual hydroxyl groups being for this reacted with the M groups.
The component B) is a propyl T resin comprising at least 80 mol % of (R³SiO_3/2)_cunits, R³being as defined above, i.e. representing an alkyl group having from 1 to 8 carbon atoms, an aryl group, a carbinol group or an amino group, c being greater than 0, provided that at least 40 mol % of the R³groups are propyl groups. Preferably, the propyl T resin according to the invention is a silsesquioxane resin. Silsesquioxane resins are well known in the state of the art and are generally obtained by hydrolysis of an organosilane comprising three hydrolyzable groups, such as halogen or alkoxy groups, present in the molecule. The component B) can thus be obtained by hydrolysis of propyltrimethoxysilane, propyltriethoxysilane or propyltripropoxysilane or by cohydrolysis of the abovementioned propylalkoxysilanes with various alkoxysilanes. Mention may be made, as examples of these alkoxysilanes, of methyltrimethoxysilane, methyltriethoxysilane, methyltriisopropoxysilane, dimethyldimethoxysilane and phenyltrimethoxysilane. Propyltrichlorosilane can also be hydrolyzed, alone or in the presence of alcohol. In this case, the cohydrolysis can be carried out by adding methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane or similar chlorosilanes and methyltrimethoxysilane, methyltriethoxysilane, methyltriisopropoxysilane or similar methylalkoxysilanes. Mention may be made, as alcohols suitable for this purpose, of methanol, ethanol, n-propyl alcohol, isopropyl alcohol, butanol, methoxyethanol, ethoxyethanol or similar alcohols. Mention may be made, as examples of solvents of hydrocarbon type which can be used, of toluene, xylene or similar aromatic hydrocarbons; hexane, heptane, isooctane or similar saturated and linear or partially branched hydrocarbons; and cyclohexane or similar aliphatic hydrocarbons.
The propyl T resins as component B) according to the invention can comprise M, D and Q units, provided that at least 80 mol %, indeed even 90 mol % of the total siloxane units are T units. The propyl T resins can also comprise hydroxyl groups. Preferably, the propyl T resins comprise between 3 and 8% by weight of hydroxyl groups.
A polyorganosiloxane can also be added to the process according to the invention as component C).
The polyorganosiloxanes of use as component C) according to the invention comprise R² ₂SiO_2/2or R³SiO_3/2units. The polyorganosiloxane can be added in order to introduce various D and T units into the MQ-propyl T resins, in order to modify the properties of the resulting resins. The structure or the formula of the polyorganosiloxane is not limiting, provided that said polyorganosiloxane comprises a measurable amount of R² ₂SiO_2/2or R³SiO_3/2units and that the total amount of polyorganosiloxane added to the reaction between A) and B) does not result in more than 50 mol % of D or T units in the reaction mixture.
The polyorganosiloxane can comprise combinations of M, D, T and Q units, provided that at least the D or T units are present. Thus, the polyorganosiloxane can be chosen from silicone fluids, gums or resins known from the prior art and comprising D or T units, or their mixtures. The D units typically comprise methyl or phenyl groups or their mixtures as R²groups. The T units typically comprise methyl or phenyl groups or their mixtures as R³groups. The polyorganosiloxane can be a fluid linear polydiorganosiloxane having a viscosity of between 10 and 1000 cS (mm²/s). The fluid polydiorganosiloxane can be a polydimethylsiloxane or a polymethylphenylsiloxane. The polyorganosiloxane can also be an organosilsesquioxane resin. The organosilsesquioxane resin is typically a methylsilsesquioxane resin or a phenylsilsesquioxane resin.
The components A), B) and optionally C) can react by any method known from the prior art for acting on M, D, T and Q units. However, preferably, the components A), B) and optionally C) react by a condensation reaction in the presence of a catalyst. The MQ resin is typically present in an aromatic hydrocarbon or siloxane solvent. Condensation reaction catalysts which can be used are in particular metal hydroxides, such as potassium hydroxide or sodium hydroxide; metal salts, such as silanolates, carboxylates and carbonates; amines; titanates, such as tetrabutyl titanate; and their mixtures. Typically, the reaction between the components A), B) and optionally C) is carried out by heating the reaction mixture to temperatures ranging from 50 to 140° C., preferably ranging from 100 to 140° C. The reaction can take place in a semicontinuous, continuous or batch process.
Preferably, said siloxane resin is obtained by a process comprising the reaction between:

- A) an MQ resin comprising at least 80 mol % of (R¹ ₂SiO_1/2)_aand (SiO_4/2)_dunits,
  - R¹representing a methyl group,

Polymer:

The compositions according to the invention can additionally comprise at least one polymer which may or may not be film-forming.
In the present invention, the term “film-forming polymer” is understood to mean a polymer capable of forming, by itself alone or in the presence of an additional agent which is able to form a film, a film which is macroscopically continuous and which adheres to keratinous substances, and preferably a cohesive film, and better still a film having a cohesion and mechanical properties such that said film can be isolable and handleable in isolation, for example when said film is produced by casting on a nonstick surface, such as a Teflon- or silicone-treated surface.
The composition can comprise an aqueous phase and the additional polymer can be present in this aqueous phase. In this case, the additional polymer will preferably be a polymer in dispersion or an amphiphilic or associative polymer.
The term “polymer in dispersion” is understood to mean water-insoluble polymers present in the form of particles of variable size. The polymer may or may not be crosslinked. The mean particle size is typically between 25 and 500 nm, preferably between 50 and 200 nm. The following polymers in aqueous dispersion can be used: Ultrasol 2075 from Ganz Chemical, Daitosol 5000AD from Daito Kasei, Avalure UR 450 from Noveon, DynamX from National Starch, Syntran 5760 from Interpolymer, Acusol OP 301 from Röhm & Haas or Neocryl A 1090 from Avecia.

The term “amphiphilic or associative polymers” is understood to mean polymers comprising one or more hydrophilic parts which render them partially soluble in water and one or more hydrophobic parts via which the polymers form an association or interact. The following associative polymers can be used: Nuvis FX1100 from Elementis, Aculyn 22, Aculyn 44, Aculyn 46 from Röhm & Haas or Viscophobe DB1000 from Amerchol. Diblock copolymers composed of a hydrophilic block (polyacrylate, polyethylene glycol) and of a hydrophobic block (polystyrene, polysiloxane) can also be used.

Polymers of NAD (nonaqueous dispersion) type or microgels (for example KSGs) can be used, and also polymers of the silicone-modified polyamide type or styrene-based copolymers (Kraton, Regalite).

The pasty compound or compounds can be present in a composition of the invention in a content ranging from 0.1 to 30% by weight of agents, more preferably from 0.5 to 20% by weight, with respect to the total weight of the composition.
The composition according to the invention can also comprise ingredients commonly used in cosmetics, such as vitamins, thickeners, trace elements, softeners, sequestering agents, fragrances, basifying or acidifying agents, preservatives, sunscreens, surfactants, antioxidants, agents for combating hair loss, antidandruff agents, propellants, or their mixtures.
Of course, a person skilled in the art will take care to choose this or these optional additional compounds and/or their amounts so that the advantageous properties of the corresponding composition according to the invention are not, or not substantially, detrimentally affected by the envisioned addition.
A composition according to the invention can in particular be provided in the form of a composition for making up and/or caring for the skin, in particular a foundation.
According to another aspect, the invention also relates to a cosmetic combination comprising:

- i) a container delimiting at least one compartment, said container being closed by a closing element; and
- ii) a composition positioned inside said compartment, the composition being in accordance with the invention.

The container can have any appropriate form. It can in particular be in the form of a bottle, a tube, a pot, a box, a tin, a bag or a case.
The closing element can be in the form of a removable stopper, of a lid, of a seal, of a tear-off strip or of a capsule, in particular of the type comprising a body fixed to the container and a cap articulated over the body. It can also be in the form of an element providing the selective closure of the container, in particular a pump, a valve or a flap.
The container can be used in combination with an applicator, in particular in the form of a brush comprising an arrangement of hairs held by a twisted wire. Such a twisted brush is described in particular in U.S. Pat. No. 4,887,622. It can also be in the form of a comb comprising a plurality of application elements, obtained in particular from molding. Such combs are described, for example, in patent FR 2 796 529. The applicator can be in the form of a fine brush, such as described, for example, in patent FR 2 722 380. The applicator can be in the form of a pad of foam or elastomer, of a felt-tipped pen or of a spatula. The applicator can be free (powder puff or sponge) or integrally attached to a rod carried by the closing element, such as described, for example, in U.S. Pat. No. 5,492,426. The applicator can be integrally attached to the container, such as described, for example, in patent FR 2 761 959.
The product may be contained directly in the container or indirectly. By way of example, the product can be positioned on an impregnated support, particularly in the form of a wipe or of a wad, and can be positioned (singly or severally) in a tin or in a bag. Such a support incorporating the product is described, for example, in application WO 01/03538.
The closing element can be coupled to the container by screwing. Alternatively, the coupling between the closing element and the container is carried out other than by screwing, in particular via a bayonet mechanism, by snapping, clamping, welding or adhesive bonding, or by magnetic attraction. The term “snapping” is understood to mean in particular any system involving the crossing of a row or strip of material by elastic deformation of a portion, in particular of the closing element, and then by elastically returning said portion to the unstressed position after the row or strip has been crossed.
The container can be at least partially made of thermoplastic material. Mention may be made, as examples of thermoplastic materials, of polypropylene or polyethylene.
Alternatively, the container is made of non-thermoplastic material, in particular of glass or of metal (or alloy).
The container can have rigid walls or deformable walls, in particular in the form of a tube or of a tube bottle.
The container can comprise means intended to bring about or facilitate the distribution of the composition. By way of example, the container can have deformable walls, so as to bring about the departure of the composition in response to excess pressurization inside the container, which excess pressurization is brought about by the elastic (or non-elastic) crushing of the walls of the container. Alternatively, in particular when the product is in the form of a stick, the latter can be driven by a piston mechanism. Still in the case of a stick, in particular of a makeup product (foundation, and the like), the container can comprise a mechanism, in particular a rack-and-pinion mechanism or a mechanism with a screw rod or a mechanism with a helical groove, capable of moving a stick in the direction of said opening. Such a mechanism is described, for example, in patent FR 2 806 273 or in patent FR 2 775 566. Such a mechanism for a liquid product is described in patent FR 2 727 609.
The container can be composed of a case with a bottom delimiting at least one receptacle comprising the composition and a lid, in particular articulated over the bottom, capable of at least partially covering said bottom. Such a case is described, for example, in application WO 03/018423 or in patent FR 2 791 042.
The container can be equipped with a drainer positioned in the vicinity of the opening of the container. Such a drainer makes it possible to wipe the applicator and optionally the rod to which it may be integrally attached. Such a drainer is described, for example, in patent FR 2 792 618.
The composition can be at atmospheric pressure inside the container (at ambient temperature) or pressurized, in particular using a propellent gas (aerosol). In the latter case, the container is equipped with a valve (of the type of those used for aerosols).
The contents of all the patents or patent applications mentioned above are incorporated by reference in the present patent application.
The composition of the invention can be provided in the form of a product for caring for or preferably making up, in particular in colored form, the skin, more specifically the face, such as a foundation, a face powder, an eyeshadow, a concealer, a blush, or a loose or compact powder, or alternatively a product for making up the body, such as a semi-permanent tattooing product.
The composition according to the invention can be manufactured by known processes used generally in the cosmetics field.
The present invention also relates to a method, more specifically a cosmetic method, for caring for or in particular making up the skin and/or superficial body growths (in particular hair or nails) comprising the application of a composition according to the invention described above to the skin and/or its superficial body growths.
The aim of the following examples is to illustrate, without any limitation, the subject matter of the present invention. In the patent application, the contents, unless expressly indicated otherwise, are expressed by weight with respect to the total weight of the composition.

Preparation of the MQT^PrResin

The following resins are used:
Resin MQ=an MQ resin of formula M_0.43Q_0.57and with M_n=3230 dissolved in xylene at 70.8% by weight of solids. The MQ resin was manufactured according to the techniques described by Daudt in patent U.S. Pat. No. 2,676,182.
Propyl T resin=a propyl silsesquioxane resin at 74.8% by weight in toluene. The propyl silsesquioxane resin was obtained by hydrolysis of propyltrichlorosilane.
An MQ resin, a propyl T resin, xylene and 1M KOH in water, in the proportions shown in table 1, are introduced into a three-necked flask equipped with a stirrer, with a temperature probe and Dean and Stark apparatus equipped with a condenser at the top. Xylene is preintroduced into the Dean and Stark apparatus in order to ensure that a level of solids at 50% is maintained in the reactor. The mixture in the reactor is maintained at a reflux temperature (between 100 and 140° C.) for at least 3 hours. Any water which is formed in the reaction mixture is continuously removed, if appropriate, and trapped in the form of an azeotrope in the Dean and Stark apparatus. After refluxing for 3 hours, the water is removed from the apparatus and heating is continued for an additional 30 minutes. After cooling the mixture, an excess of acetic acid is added in order to neutralize the KOH in the mixture. The mixture is subsequently filtered, in order to remove the salts formed, by passing it through a filter under pressure. A solvent exchange is carried out by heating the mixture in a rotary evaporator under vacuum. After removing the majority of the xylene, decamethylcyclopentasiloxane or isododecane is added while continuing to remove any residual aromatic solvent. The structures of the resulting siloxane resins are characterized by ²⁹Si NMR spectroscopy and GPC and the results are summarized in table 2 below.

Procedure

The constituents of phase A2 are weighed out. The mixture is passed through a triple roll mill. The constituents of phase A1 are subsequently weighed out into the main beaker and the latter is placed in a water bath (75-80° C.). When the mixture is homogeneous, it is cooled to ambient temperature.
A2 is incorporated in phase A1 with stirring with a Moritz stirrer at 1500 revolutions/min. The constituents of phase A3 are then successively added while retaining the same stirring.
The constituents of phase B are weighed out. Phase B is brought to boiling, until the constituents have completely dissolved. Phase B is cooled to 50° C.
Phase B is subsequently trickled into phase A1+A2+A3 while stirring with a Moritz stirrer at 3200 rev/min.

Protocol for Instrumental Measurements of the Immediate Mattness and the Persistence of the Mattness

The mattness and the persistence of the mattness can be measured using the protocol described below.
The mattness of a region of the skin, for example the face, is measured using a polarimetric camera, which is a black and white polarimetric imaging system, with which images are acquired in parallel (P) and crossed (C) polarized light.
By analyzing the image resulting from the subtraction of the two images (P-C), the shine is quantified by measuring the mean level of gray of the 5% of shiniest pixels corresponding to the regions of shine.
More specifically, the measurements are carried out on a panel of individuals who are kept in an air-conditioned (22° C.+/−2° C.) waiting room for 15 min before the beginning of the test. They remove their makeup and an image of one of their cheeks is acquired with the polarimetric camera. This image makes it possible to measure the shine at T0 before applying makeup. Approximately 100 mg of each cosmetic composition as prepared above are then weighed out into a watch glass and are applied with the bare fingers to the half of the face on which the T0 measurement was carried out.
After a drying time of 15 min, an image of the made-up cheek is acquired with the polarimetric camera. This image makes it possible to measure the shine immediately after applying makeup (Timm). The models then return to the air-conditioned room for 3 h.
Finally, an image of the made-up cheek after waiting for 3 h is acquired with the polarimetric camera. This image makes it possible to measure the shine after wearing makeup for 3 h (T3 h).
The results are expressed by calculating the difference (Timm−T0), which measures the effect of the makeup. A negative value means that the makeup reduces the shine of the skin and that it is thus mattifying.
The difference (T3 h−Timm) measuring the persistence of this effect is subsequently calculated. The value obtained should be as low as possible, which means that the mattness of the makeup does not change over time.
For the measurements carried out, it is considered that:
+ slight effect or low persistence
++ moderate effect or moderate persistence
+++ significant effect or good persistence
++++ very significant effect or very good persistence

Protocol for Instrumental Measurements of the Immediate Color and the Persistence of the Color

Use is made of the same protocol as above for the mattness but, instead of measuring the shine, a colorimetric measurement of the skin, before and after applying makeup, is carried out by measuring the a*,b* and L* indices, namely the red and yellow indices and the brightness.
For each woman, an image of the cheeks is taken at T0 (before applying makeup), at Timm (15 minutes after applying makeup) and at T3 h (3 h after applying makeup), using a chromasphere, with a definition of 410×410 pixels.
Each image obtained with the camera is made use of in color. The color is quantified by the red and yellow indices, the brightness and the color difference (respectively a*,b*, L* and deltaE).
The deltaE, dE or ΔE is defined as a measurement of difference between two colors. The formula established in 1976 is shown below:
ΔE*=√{square root over (((L ₁ −L ₂)²+(a ₁ −a ₂)²+(b ₁ −b ₂)²)}{square root over (((L ₁ −L ₂)²+(a ₁ −a ₂)²+(b ₁ −b ₂)²)}{square root over (((L ₁ −L ₂)²+(a ₁ −a ₂)²+(b ₁ −b ₂)²)}, where:
L₁, a₁and b₁are the coordinates in the colorimetric space of the first color to be compared and L₂, a₂and b₂those of the second.

Results

In terms of persistence of the cosmetic properties, examples 2, 3, 4 and 5 exhibit good persistence of the cosmetic properties (mattness and color):
(T3 h−Timm) grading +++
On the other hand, disparities are observed in terms of comfort on application and of makeup result.
Specifically, a sensory evaluation of said compositions was carried out on a panel of individuals who use foundation. After free application of each composition to the face, each individual evaluates the perception of said composition at the time of application and in terms of makeup result. For examples 3 and 4 according to the invention, application is easy without a “crunching” effect on the skin. The product glides perfectly under the fingers, which makes application pleasant. The makeup finish is soft to the touch and nontacky.
Conversely, when formulations 2 and 5, which are comparative examples, are applied, rubbing over the skin is felt, which makes application uncomfortable and bothersome. The makeup finish is much less soft to the touch.
These results show that the fillers of inorganic nature, such as talc and silica, make it possible, in combination with the siloxane resins according to the invention, to confer good persistence on the cosmetic properties (mattness and color) while giving the composition good properties of comfort on application (soft and nontacky touch), in comparison with organic fillers, such as organic fillers of polyamide (nylon-12) type or siloxane elastomer powders (KSP300) type. The latter can be used as additional fillers but necessarily in combination with at least one inorganic filler in an amount which is predominant or at least equal to the sum of the organic fillers according to the invention.
