Definitions

  • the subject of the present invention is a composition intended more particularly for making up and/or caring for the lips, which is in a liquid form and which comprises at least 70% by weight of non- volatile oils, at least one mineral thickener, less than 1% by weight of a non-ionic silicone surfactant, and coloured or non-coloured solid particles.
  • the present invention also relates to a process using said composition, consisting in applying it to the lips.
  • Formulas intended for making up and/or caring for the lips have been known for a very long time and are in varied forms, ranging from fluid formulas such as glosses, to optionally supported solid compositions in the form of a stick, or even compositions in the form of a pencil.
  • compositions comprise relatively low contents of solid particles.
  • ranges of shades and the colour results (in terms of coverage for example) that are accessible are limited.
  • the compositions can also comprise dyes, therefore species that are soluble in the medium in which they are used.
  • the number of dyes that can be used in this field is relatively restricted, which does not allow a great deal of extension of the range of colours proposed or of their intensity, whether or not the dyes are combined with coloured solid particles.
  • compositions intended for making up and/or caring for the lips which comprise high contents of non-volatile oils, which make it possible to obtain a wider range of tints and of colour effects (in particular coverage) without loss of a very fluid texture and which are despite everything stable with respect to storage.
  • liquid cosmetic compositions comprising:
  • composition * at least 70% by weight, relative to the weight of the composition, of at least one non-volatile oil or of a single -phase mixture of several non-volatile oils, the composition comprising at least one polar or non-polar, non-volatile hydrocarbon-based oil;
  • a subject of the invention is also a process for making up and/or caring for the lips, consisting in applying such a composition.
  • the present invention therefore makes it possible to provide compositions which are stable with respect to storage, and which remain very fluid and can however contain pigment, dye and/or filler contents that are higher than those envisaged in the existing compositions of this type.
  • composition makes it possible to obtain a deposit in more extended tint ranges, with more intense colour effects.
  • composition is also easy to apply, and gives a non-tacky, comfortable uniform deposit which covers better than the existing very fluid compositions.
  • composition according to the invention is in the form of a liquid at ambient temperature (25°C) and atmospheric pressure (1.013xl0 5 Pa).
  • the viscosity of the composition varies between 0.2 and 0.8 Pa.s, preferably between 0.3 and 0.7 Pa.s.
  • the viscosity measurement is generally performed at 25°C, using a Rheomat RM180 viscometer equipped with a No. 2 spindle, the measurement being performed after 10 minutes of rotation of the spindle in the composition (after which time stabilization of the viscosity and of the spin speed of the spindle are observed), at 200 rpm. As previously indicated, the composition does not sediment.
  • composition is said not to sediment when it allows little or no appearance of a supernatant liquid after standing for 48 hours at 25 °C, measured under the following conditions:
  • the measurements are carried out in a cylindrical polyethylene terephthalate receptacle, the height of which is 46.9 mm and the radius of which is 15 mm, comprising two steel balls 6.35 mm in diameter, and fitted with a stopper.
  • the composition is introduced such that the height in the bottle reaches 3.5 cm (which represents approximately 4.5 g of composition) and the bottle is stoppered.
  • Said bottle is left for 48 hours at a temperature of 25°C.
  • the composition according to the invention comprises at least 70% by weight, relative to the weight of the composition, of at least one non-volatile oil or of a single-phase mixture of several non- volatile oils.
  • the mixture is said to be single-phase when no phase separation is observed by eye or under a phase-contrast microscope, at ambient temperature (25°C) after homogenization at temperature and mixing on a Rayneri mixer (550 rpm, 10 minutes) and storage while left to stand in a closed receptacle at ambient temperature for 24 hours (and atmospheric pressure). Under these conditions, the term stable single-phase mixture is used.
  • the composition comprises one or more non-volatile oils chosen from polar or non-polar hydrocarbon-based oils.
  • oil denotes nonaqueous compounds that are liquid at 25°C and atmospheric pressure (1.013 x. lO 5 Pa), and water-immiscible.
  • oil denotes nonaqueous compounds that are liquid at 25°C and atmospheric pressure (1.013 x. lO 5 Pa), and water-immiscible.
  • the term “immiscible” is intended to mean that the mixing of the same amount of water and oil, after mixing (for example Rayneri 550 rpm; 10 minutes), does not result in a stable solution comprising just one phase, under normal temperature and pressure conditions.
  • non-volatile oil is intended to mean an oil of which the vapour pressure at 25°C and atmospheric pressure is non-zero and is less than 0.02 mmHg (2.66 Pa) and better still less than 10 "3 mmHg (0.13 Pa).

Description

LIQUID COSMETIC COMPOSITION COMPRISING A HIGH NON- VOLATILE OIL CONTENT AND A NON-IONIC SILICONE SURFACTANT, AND LIP
TREATMENT PROCESS The subject of the present invention is a composition intended more particularly for making up and/or caring for the lips, which is in a liquid form and which comprises at least 70% by weight of non- volatile oils, at least one mineral thickener, less than 1% by weight of a non-ionic silicone surfactant, and coloured or non-coloured solid particles. The present invention also relates to a process using said composition, consisting in applying it to the lips.
Formulas intended for making up and/or caring for the lips have been known for a very long time and are in varied forms, ranging from fluid formulas such as glosses, to optionally supported solid compositions in the form of a stick, or even compositions in the form of a pencil.
In order to further diversify the compositions provided to consumers, anhydrous or virtually anhydrous formulas, which are even more fluid than the glosses, and which comprise high contents of oils, that are very comfortable to wear, have emerged. However, these formulas are available only in versions that are not very coloured. This comes essentially from the fact that it is very difficult to maintain high contents of particles in suspension in this type of oily medium, without losing the attraction of such compositions, which is precisely their great fluidity.
Indeed, with large amounts of pigments, nacres or fillers, sedimentation of these particles is observed, resulting in the formation of a relatively unattractive cake which can comprise clumps of particles. The cake thus formed has the additional drawback of being very cohesive. Thus, it cannot be easily redispersed so as to again have a uniform composition. Consequently, once the particles have sedimented, the composition becomes virtually unusable and no longer makes it possible to obtain a uniform deposit on the lips, which is not acceptable.
Thus, in order to minimize the sedimentation problem, these compositions comprise relatively low contents of solid particles. However, in this case, the ranges of shades and the colour results (in terms of coverage for example) that are accessible are limited. The compositions can also comprise dyes, therefore species that are soluble in the medium in which they are used. However, the number of dyes that can be used in this field is relatively restricted, which does not allow a great deal of extension of the range of colours proposed or of their intensity, whether or not the dyes are combined with coloured solid particles.
It is therefore sought to obtain compositions intended for making up and/or caring for the lips, which comprise high contents of non-volatile oils, which make it possible to obtain a wider range of tints and of colour effects (in particular coverage) without loss of a very fluid texture and which are despite everything stable with respect to storage.
These aims and others are achieved by the present invention, a subject of which is thus liquid cosmetic compositions comprising:
* at least 70% by weight, relative to the weight of the composition, of at least one non-volatile oil or of a single -phase mixture of several non-volatile oils, the composition comprising at least one polar or non-polar, non-volatile hydrocarbon-based oil;
* at least one mineral thickener;
* at least one non-ionic silicone surfactant in a content of less than 1% by weight, relative to the weight of the composition;
* at least coloured or non-coloured solid particles.
A subject of the invention is also a process for making up and/or caring for the lips, consisting in applying such a composition.
The present invention therefore makes it possible to provide compositions which are stable with respect to storage, and which remain very fluid and can however contain pigment, dye and/or filler contents that are higher than those envisaged in the existing compositions of this type.
Thus, the composition makes it possible to obtain a deposit in more extended tint ranges, with more intense colour effects.
The composition is also easy to apply, and gives a non-tacky, comfortable uniform deposit which covers better than the existing very fluid compositions.
Other advantages of the present invention will emerge more clearly on reading the description and the examples that follow.
In what follows, the wording "comprising a" or "containing a" means "comprising at least one" or "containing at least one", unless otherwise specified. The expressions "at least one" and "several" are used without distinction.
Furthermore, unless otherwise indicated, the limits indicated for a range are included in that range.
The composition according to the invention is in the form of a liquid at ambient temperature (25°C) and atmospheric pressure (1.013xl05 Pa).
More particularly, the viscosity of the composition varies between 0.2 and 0.8 Pa.s, preferably between 0.3 and 0.7 Pa.s.
The viscosity measurement is generally performed at 25°C, using a Rheomat RM180 viscometer equipped with a No. 2 spindle, the measurement being performed after 10 minutes of rotation of the spindle in the composition (after which time stabilization of the viscosity and of the spin speed of the spindle are observed), at 200 rpm. As previously indicated, the composition does not sediment.
The composition is said not to sediment when it allows little or no appearance of a supernatant liquid after standing for 48 hours at 25 °C, measured under the following conditions:
The measurements are carried out in a cylindrical polyethylene terephthalate receptacle, the height of which is 46.9 mm and the radius of which is 15 mm, comprising two steel balls 6.35 mm in diameter, and fitted with a stopper.
The composition is introduced such that the height in the bottle reaches 3.5 cm (which represents approximately 4.5 g of composition) and the bottle is stoppered.
Said bottle is left for 48 hours at a temperature of 25°C.
After the 48 hours, the height of supernatant liquid is measured.
It is considered that the composition is stable when the composition allows no supernatant liquid to appear. NON- VOLATILE OILS
As previously indicated, the composition according to the invention comprises at least 70% by weight, relative to the weight of the composition, of at least one non-volatile oil or of a single-phase mixture of several non- volatile oils.
The mixture is said to be single-phase when no phase separation is observed by eye or under a phase-contrast microscope, at ambient temperature (25°C) after homogenization at temperature and mixing on a Rayneri mixer (550 rpm, 10 minutes) and storage while left to stand in a closed receptacle at ambient temperature for 24 hours (and atmospheric pressure). Under these conditions, the term stable single-phase mixture is used.
As previously indicated, the composition comprises one or more non-volatile oils chosen from polar or non-polar hydrocarbon-based oils.
More particularly, for the purposes of the invention, the word "oil" denotes nonaqueous compounds that are liquid at 25°C and atmospheric pressure (1.013 x. lO5 Pa), and water-immiscible. The term "immiscible" is intended to mean that the mixing of the same amount of water and oil, after mixing (for example Rayneri 550 rpm; 10 minutes), does not result in a stable solution comprising just one phase, under normal temperature and pressure conditions.
The term "non-volatile oil" is intended to mean an oil of which the vapour pressure at 25°C and atmospheric pressure is non-zero and is less than 0.02 mmHg (2.66 Pa) and better still less than 10"3 mmHg (0.13 Pa).
The term "hydrocarbon-based oil" is intended to mean an oil formed essentially from, or even constituted by, carbon and hydrogen atoms, and optionally oxygen and nitrogen atoms, and not containing any silicon or fluorine atoms. For the purposes of the present invention, the term "non-polar oil" is intended to mean an oil chosen from hydrocarbons, i.e. from compounds comprising only carbon and hydrogen atoms. Non-polar non-volatile hydrocarbon-based oils
These oils may be of plant, mineral or synthetic origin.
More particularly, the non-polar non-volatile hydrocarbon-based oil(s) can be chosen from linear or branched hydrocarbons of mineral or synthetic origin.
For example, the following are suitable for carrying out the present invention:
- liquid paraffins,
- squalane,
- isohexadecane,
- isoeicosane,
- naphthalene oil,
- polybutenes, for instance Indopol H-100 (molar mass or MW = 965 g/mol),
Indopol H-300 (MW = 1340 g/mol) and Indopol H-1500 (MW = 2160 g/mol) sold or manufactured by the company Amoco,
- polyisobutenes, hydrogenated polyisobutenes, for instance Parleam® sold by the company Nippon Oil Fats, Panalane H-300 E sold or manufactured by the company Amoco (MW = 1340 g/mol), Viseal 20000 sold or manufactured by the company Synteal (MW = 6000 g/mol) and Rewopal PIB 1000 sold or manufactured by the company Witco (MW = 1000 g/mol), or alternatively Parleam Lite sold by NOF Corporation,
- decene/butene copolymers and polybutene/polyisobutene copolymers, in particular Indopol L-14,
- polydecenes and hydrogenated polydecenes, for instance: Puresyn 10 (MW = 723 g/mol) and Puresyn 150 (MW = 9200 g/mol) sold or manufactured by the company Mobil Chemicals, or alternatively Puresyn 6 sold by ExxonMobil Chemical,
- and mixtures thereof. Preferably, the non-polar non-volatile hydrocarbon-based oil(s) are chosen from hydrogenated or non-hydrogenated polybutenes, hydrogenated or non-hydrogenated polyisobutenes and hydrogenated or non-hydrogenated polydecenes, and also mixtures thereof. Polar non- volatile hydrocarbon-based oils
These polar hydrocarbon-based oils are thus formed from carbon and hydrogen atoms, and comprise at least one or more oxygen or nitrogen atoms, but are free of silicon or fluorine atoms. They consequently contain at least one group chosen from alcohol, ester, ether, carboxylic acid, amine and/or amide functions.
Preferably, the polar non-volatile hydrocarbon-based oils are, in addition to being free of silicon and fluorine, free of heteroatoms such as nitrogen and phosphorus.
In the present case, the polar non-volatile hydrocarbon-based oils therefore comprise one or more oxygen atoms as heteroatom.
In particular, the polar non-volatile hydrocarbon-based oil(s) comprise at least one alcohol function (it is then an "alcohol oil") or at least one ester function (it is then an "ester oil"). It should be noted that the ester oils may in particular be hydroxylated.
The composition may comprise one or more non-volatile hydrocarbon-based oils, in particular chosen from:
- saturated or unsaturated, branched or non-branched Cm-C^, in particular C10-C24 and preferably C12-C22 alcohols, more particularly monoalcohols.
Advantageously, the C10-C26 alcohols are fatty monoalcohols, which are preferably branched when they comprise at least 16 carbon atoms.
As examples of fatty alcohols that may be used according to the invention, mention may be made of linear or branched fatty alcohols, of synthetic origin or alternatively of natural origin, for instance alcohols derived from plant material (coconut, palm kernel, palm, etc.) or animal material (tallow, etc.).

Mention may also be made, for example, of fumed silica preferably hydrophobically treated at the surface, the size of the particles of which is more particularly less than 1 μιη. Silanol groups can in particular be replaced by hydrophobic groups: a hydrophobic silica is then obtained. The hydrophobic groups can be:
- trimethylsiloxyl groups, which are obtained in particular by treating fumed silica in the presence of hexamethyldisilazane. Silicas thus treated are known as "Silica silylate" according to the CTFA (6th edition, 1995). They are sold, for example, under the references Aerosil R812 by the company Degussa, and Cab-O-Sil TS-53(F by the company Cabot;

Silicas thus treated are known as "Silica dimethyl silylate" according to the CTFA (6th edition, 1995). They are sold, for example, under the references Aerosil R972 and Aerosil R974 by the company Degussa, and Cab-O-Sil TS-610® and Cab-O-Sil TS-720® by the company Cabot.
The hydrophobic fumed silica in particular has a particle size ranging, for example, from 5 to 200 nm.
Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air.
They are generally synthesized via a sol-gel process in a liquid medium and then dried, usually by extraction with a supercritical fluid, the one most commonly used being supercritical C02. Drying of this type makes it possible to avoid contraction of the pores and of the material. The sol-gel process and the various drying operations are described in detail in Brinker C.J., and Scherer G.W., Sol-Gel Science, New York, Academic Press, 1990.
The hydrophobic silica aerogel particles that can be used have a specific surface area
2 2 per unit mass (SM) ranging from 500 to 1500 m /g, preferably from 600 to 1200 m /g and better still from 600 to 800 m /g, and a size expressed as the volume mean diameter (D[0.5]) ranging from 1 to 1500 μιη, better still from 1 to 1000 μιη, preferably from 1 to 100 μιη, in particular from 1 to 30 μιη, more preferably from 5 to 25 μιη, better still from 5 to 20 μιη and even better still from 5 to 15 μιη.
According to one embodiment, the hydrophobic silica aerogel particles that are suitable have a size expressed as the volume mean diameter (D[0.5]) ranging from 1 to 30 μιη, preferably from 5 to 25 μιη, better still from 5 to 20 μιη and even better still from 5 to 15 μιη.
The specific surface area per unit mass may be determined by the nitrogen absorption method, known as the BET (Brunauer-Emmett- Teller) method, described in The Journal of the American Chemical Society, vol. 60, page 309, February 1938 and corresponding to international standard ISO 5794/1 (appendix D). The BET specific surface area corresponds to the total specific surface area of the particles under consideration.
The sizes of the silica aerogel particles can be measured by static light scattering using a commercial particle size analyser of MasterSizer 2000 type from Malvern. The data are processed on the basis of the Mie scattering theory. This theory, which is exact for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" particle diameter. This theory is in particular described in the publication by Van de Hulst, H.C., Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.
According to an advantageous embodiment, the hydrophobic silica aerogel particles that can be used according to the invention have a specific surface area per unit mass (SM) ranging from 600 to 800 m /g and a size expressed as the volume mean diameter (D[0.5]) ranging from 5 to 20 μιη and even better still from 5 to 15 μιη.
The silica aerogel particles that can be used may advantageously have a tapped density σ ranging from 0.02 g/cm3 to 0.10 g/cm3, preferably from 0.03 g/cm3 to 0.08 g/cm 3 , preferably from 0.05 g/cm 3 to 0.08 g/cm 3.
In the context of the present invention, this density, known as the tapped density, may be assessed according to the following protocol:
40 g of powder are poured into a graduated measuring cylinder; the measuring cylinder is then placed on the Stav 2003 device from Stampf Volumeter; the measuring cylinder is subsequently subjected to a series of 2500 tapping actions (this operation is repeated until the difference in volume between two consecutive tests is less than 2%) and then the final volume Vf of tapped powder is measured directly on the measuring cylinder.
The tapped density is determined by the ratio m/Vf, in this instance 40/Vf (Vf being expressed in cm3 and m in g).
According to a preferred embodiment, the hydrophobic silica aerogel particles that can be used have a specific surface area per unit of volume Sv ranging from 5 to 60 m 2 /cm 3 , preferably from 10 to 50 m 2 /cm 3 and better still from 15 to 40 m 2 /cm 3.
The specific surface area per unit of volume is given by the relationship: Sy = SM X σ, where σ is the tapped density, expressed in g/cm3, and SM is the specific surface area per unit mass, expressed in m /g, as defined above.
The aerogels used according to the present invention are hydrophobic silica aerogels, preferably of silyl silica (INCI name: silica silylate).
"Hydrophobic silica" is intended to mean any silica, the surface of which is treated with silylating agents, for example with halogenated silanes, such as alkylchlorosilanes, siloxanes, in particular dimethylsiloxanes, such as hexamethyldisiloxane, or silazanes, so as to functionalize the OH groups with silyl groups Si-Rn, for example trimethylsilyl groups.
As regards the preparation of hydrophobic silica aerogel particles modified at the surface by silylation, reference may be made to the document US 7 470 725.
Use will preferably be made of hydrophobic silica aerogel particles modified at the surface by trimethylsilyl groups.
As hydrophobic silica aerogels that may be used in the invention, examples that may be mentioned include the aerogel sold under the name VM-2260 (INCI name: silica silylate), by the company Dow Corning, the particles of which have a mean size of about
1000 microns and a specific surface area per unit of mass ranging from 600 to 800 m /g.

The pigments may also have been subjected to a hydrophobic treatment.
The hydrophobic treatment agent may be chosen from silicones such as methicones, dimethicones and perfluoroalkylsilanes; fatty acids such as stearic acid; metal soaps such as aluminium dimyristate, the aluminium salt of hydrogenated tallow glutamate, perfluoroalkyl phosphates, perfluoroalkylsilanes, perfluoroalkylsilazanes, polyhexafluoropropylene oxides, polyorganosiloxanes comprising perfluoroalkyl perfluoropolyether groups and amino acids; N-acylamino acids or salts thereof; lecithin, isopropyl triisostearyl titanate, and mixtures thereof.
The N-acylamino acids may comprise an acyl group containing from 8 to 22 carbon atoms, for instance a 2-ethylhexanoyl, caproyl, lauroyl, myristoyl, palmitoyl, stearoyl or cocoyl group. The salts of these compounds may be the aluminium, magnesium, calcium, zirconium, zinc, sodium or potassium salts. The amino acid may be, for example, lysine, glutamic acid or alanine.
The term "alkyl" mentioned in the compounds cited above in particular denotes an alkyl group containing from 1 to 30 carbon atoms and preferably containing from 5 to 16 carbon atoms.
Hydrophobic treated pigments are described in particular in patent application EP-A-1 086 683.
The dyestuff may also comprise a pigment having a structure which may be, for example, of the type such as silica microspheres containing iron oxide. An example of a pigment having this structure is the product sold by the company Miyoshi under the reference PC Ball PC-LL-100 P, this pigment being constituted of silica microspheres containing yellow iron oxide.
For the purposes of the present invention, the nacres are more particularly coloured particles of any form, which may or may not be iridescent, in particular produced by certain molluscs in their shell, or alternatively synthesized, and which have a colour effect via optical interference.
Examples of nacres that may be mentioned include nacreous pigments such as titanium mica coated with an iron oxide, mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, titanium mica coated with an organic dye in particular of the abovementioned type, and also nacreous pigments based on bismuth oxychloride. They may also be mica particles, on the surface of which are superposed at least two successive layers of metal oxides and/or of organic dyestuffs.
The nacres may more particularly have a yellow, pink, red, bronze, orange, brown, gold and/or coppery colour or tint.
As illustrations of nacres that may be introduced as interference pigments into the first composition, mention may be made of the gold-coloured nacres sold in particular by the company Engelhard under the name Brilliant gold 212G (Timica), Gold 222C (Cloisonne), Sparkle gold (Timica), Gold 4504 (Chromalite) and Monarch gold 233X (Cloisonne); the bronze nacres sold in particular by the company Merck under the name Bronze fine (17384) (Colorona) and Bronze (17353) (Colorona) and by the company Engelhard under the name Super bronze (Cloisonne); the orange nacres sold in particular by the company Engelhard under the name Orange 363C (Cloisonne) and Orange MCR 101 (Cosmica) and by the company Merck under the name Passion orange (Colorona) and Matte orange (17449) (Microna); the brown nacres sold in particular by the company Engelhard under the name Nu-antique copper 340XB (Cloisonne) and Brown CL4509 (Chromalite); the nacres with a copper tint sold in particular by the company Engelhard under the name Copper 340 A (Timica); the nacres with a red tint sold in particular by the company Merck under the name Sienna fine (17386) (Colorona); the nacres with a yellow tint sold in particular by the company Engelhard under the name Yellow (4502) (Chromalite); the red nacres with a gold tint sold in particular by the company Engelhard under the name Sunstone GO 12 (Gemtone); the pink nacres sold in particular by the company Engelhard under the name Tan opale G005 (Gemtone); the black nacres with a gold tint sold in particular by the company Engelhard under the name Nu antique bronze 240 AB (Timica), the blue nacres sold in particular by the company Merck under the name Matte blue (17433) (Microna), the white nacres with a silvery tint sold in particular by the company Merck under the name Xirona Silver, and the golden-green pink-orange nacres sold in particular by the company Merck under the name Indian summer (Xirona), and mixtures thereof.
The composition may also contain, as coloured particles, at least one material with a specific optical effect.
This effect is different from a simple conventional hue effect, i.e. a unified and stabilized effect as produced by standard coloured particles, for instance monochromatic pigments. For the purposes of the invention, the term "stabilized" is intended to mean lacking the effect of variability of the colour with the angle of observation or in response to a temperature change.
For example, this material may be chosen from particles with a metallic glint, goniochromatic colouring agents, diffractive pigments, thermochromic agents, optical brighteners, and also fibres, in particular interference fibres. Needless to say, these various materials may be combined so as to afford the simultaneous manifestation of two effects, or even of a novel effect. Advantageously, the content of coloured particles, in particular of pigments, of nacres alone or as mixtures, ranges from 0.001% to 10% by weight and preferably from 0.01% to 8% by weight relative to the weight of the composition.
Fillers
The fillers are more particularly organic, mineral or mixed, and may be present alone or as a mixture.
The term "fillers" should be understood as meaning colourless or white solid particles of any form, which are in an insoluble and dispersed form in the medium of the composition, and which are not intended to colour the composition, but at the very most to opacify it.
The fillers may be, for example, platelet- shaped, spherical, oblong or fibrous, or of any other form intermediate between these forms, irrespective of the crystallographic form (for example sheet, cubic, hexagonal, orthorhombic, etc.). Preferably, the fillers used are platelet -shaped.
It should be noted that the fillers are different from the mineral thickener previously mentioned.

The term "polymer" is intended to mean herein a compound containing one or more repeating unit(s) and preferably at least 2 repeating units.
Silicone resins of MQ type
More generally, the term "resin" is intended to mean a compound whose structure is three-dimensional.
"Silicone resins" are also referred to as "siloxane resins". Thus, for the purposes of the present invention, a polydimethylsiloxane is not a silicone resin. The nomenclature of silicone resins is known under the name "MDTQ", the resin being described as a function of the various siloxane monomer units that it comprises, each of the letters "MDTQ" characterizing a type of unit.
The letter M represents the monofunctional unit of formula R 1 R2 R 3 SiOi/2, the silicon atom being connected to only one oxygen atom in the polymer comprising this unit.
The letter "D" signifies a difunctional unit R 1 R 2
S1O2/2 in which the silicon atom is bonded to two oxygen atoms.
The letter "T" represents a trifunctional unit of formula R^iC^.
Finally, the letter "Q" signifies a tetrafunctional unit Si04/2 in which the silicon atom is bonded to four oxygen atoms, which are themselves bonded to the rest of the polymer.
In the units M, D and T defined previously, R 1 , R2 and R 3 represent a hydrocarbon- based radical (in particular alkyl) containing from 1 to 10 carbon atoms, a phenyl group, a phenylalkyl group or even a hydroxyl group.
