Description

"Cosmetic composition comprising a synthetic phyllosilicate and a polyol and / or a UV filter"

The present invention relates to compositions, in particular cosmetics, such as emulsions, comprising at least one synthetic phyllosilicate and at least one polyol and / or derived from polyols and / or at least one UV filter. When at least one UV filter is present, the present invention also relates to compositions, preferably cosmetic or dermatological, photoprotective, also called solar products or photoprotective products, and more particularly emulsion type, gel or emulsified gel. More particularly, it relates to the field of care, hygiene, protection and / or make-up of the skin and / or nails, and in particular of the skin of the face and / or the body.

By "skin" is meant the skin of the face and / or the body.

By "nails" is also meant the false nails insofar as the desired cosmetic effects are very often identical.

It is known that keratin materials such as the skin tend to dry out due to environmental factors (pollution, wind, cold, air conditioning), psychological (fatigue, stress) or hormonal (menopause). If it is important that the skin is well hydrated and does not lose water, it may wilt and dry the skin. Consumers expect their cosmetic products to moisturize their skin.

The sensation of hydrated skin is conveyed, on application, by products offering an aqueous sensation. An aqueous sensation is often associated with a residual cool effect provided by the composition. By composition providing a fresh residual effect is meant a composition which, after application, induces a reduction of the perceptible cutaneous temperature, for example by at least 0.5 ° C., this cool effect during the application up to minus 4 minutes after application.

In the longer term, the feeling of hydrated skin is conveyed by a feeling of soft skin and upper layers of the epidermis hydrated.

To provide this hydration of the upper layers of the epidermis, it is common to incorporate humectants, which are hygroscopic substances that cause rehydration of the skin by capturing atmospheric water and by retention of water in the skin . Examples of these humectants are the constituents of the NMF (Natural Moisturizing Factor), such as urea, or polyols, which includes sugars and glycols.

The moisturizing effectiveness of these humectants is even more important that their rate is important.

In addition, the skin of the face and / or the body, is daily exposed to sunlight.

It is known that radiations of wavelength between 280 nm and 400 nm allow bronzing of the human epidermis and that radiation of wavelength between 280 nm and 320 nm, known as UV rays. -B impair the development of natural tanning. Exposure is also likely to induce an alteration of the biomechanical properties of the epidermis which results in the appearance of wrinkles leading to premature aging of the skin.

It is also known that UV-A rays of wavelengths between 320 nm and 400 nm penetrate deeper into the skin than UV-B rays. UV-A rays cause immediate and persistent browning of the skin. Daily exposure to UVA rays, even for short periods of time, under normal conditions can lead to degradation of collagen and elastin fibers which results in a modification of the micro-relief of the skin, the appearance of wrinkles and irregular pigmentation (brown spots, heterogeneity of complexion).

Many photoprotective compositions have been proposed to date to remedy the effects induced by UVA and / or UVB radiation.

In order to counteract these harmful effects, it is common practice to use photoprotective compositions in which organic or inorganic UV (or sunscreen) filters are formulated.

One of the major challenges for this type of photoprotective formulations is to introduce high performance UV filters, that is to say ensuring optimal UV protection to the desired indices, while providing a good level of sensoriality and cosmetic approval. to encourage the use of sunscreens and thus protect the skin from aggressions by ultraviolet rays.

In order to guarantee high solar indices, these UV filters can be used at high concentrations, sometimes more than 20% by weight relative to the total weight of a composition. However, as explained below, these humectants and UV filters have certain disadvantages, including that of affecting the sensory properties of the products, in particular by providing undesired effects.

Indeed, the introduction of these humectants, especially polyols such as glycerine, in a physiologically acceptable medium, can cause an alteration of the sensory properties of the products, providing a tacky effect, and reducing the aqueous sensation to the application. This sensory alteration which causes an impression of lack of moisturizing effectiveness to the application is all the more important that the polyol content is important.

In addition, the polyols, such as sugars and their derivatives, are capable of forming formulas which "slip" at the application, making their penetration difficult, and which can provide a soaping effect to the application. These disadvantages are particularly noticeable when the polyol is a sugar derivative such as an alkylpolyglucoside and / or a sucrose ester or a glucose ether, very often used as emulsifiers.

This soaping effect is all the stronger when the composition does not contain silicone fatty substance.

Finally, it should be noted that the combination with these polyols of certain active ingredients, especially anti-aging, may accentuate these alterations.

With regard to sunscreens, their use in cosmetic compositions degrades the sensory pleasure of support architectures. Indeed, in general, the UV filters, depending on whether they are water-soluble or fat-soluble, bring different types of inconveniences or discomforts such as a tacky, greasy, coarse or sluggish effect on the skin, a lack of freshness, and comfort.

In addition, the introduction of these sunscreens into emulsified and / or gelled galenics causes destabilization problems. This instability can even sometimes cause a dephasing of the emulsion and / or a loss of viscosity of the composition, rendering the formulation ineffective or even unusable. There remains therefore the need to provide compositions having a feeling of hydration with satisfactory application. , and a real moisturizing effectiveness on the skin after application. There is therefore also the need to produce cosmetic compositions which are both non-tacky, aqueous on application and containing at least one polyol, in particular a glycol such as glycerine,

In particular, there is a need to produce cosmetic compositions which are both non-tacky, aqueous on application and contain a high level of a polyol, in particular a glycol such as this. than glycerine.

There is also a need to prepare compositions that provide little or no wet effect to the application, or sticky effect, without feeling greasy and whose drying time after application to the skin and / or nails is shortened compared to compositions known in the cosmetic field.

There is also the need to realize different types of architectures providing a good level of sensory pleasure especially in terms of lightness effect or even freshness with a substantial reduction of the fatty residue, the sticky effect, the effect rough and / or shiny effect on the skin. The present invention is intended to meet this need while aiming to enhance the effectiveness of these compositions in terms of photoprotection.

The inventors have found, surprisingly, that the use of a synthetic phyllosilicate in combination with these polyols and / or polyol derivatives and / or UV filters, made it possible to obtain products which have no sticky effect, which do not "slip" and whose whitening effect during or after application is reduced.

Thus, the subject of the present invention is a composition, in particular a cosmetic composition, comprising:

- (a) at least one synthetic phyllosilicate of molecular formula Mg ₃ Si ₄ O 10 (OH) ₂ ; and

- (b) at least one polyol, and / or derived from polyols and / or at least one UV filter. According to a particular embodiment, a composition of the invention comprises:

- (b) at least one polyol, and / or derived from polyols. According to another particular embodiment, a composition of the invention comprises:

- (b) at least one UV filter.

According to another particular embodiment, a composition of the invention comprises:

- (a) at least one synthetic phyllosilicate of molecular formula

- (b) at least one polyol and / or polyol derivative;

- (c) at least one aqueous phase; and

- (d) at least one fatty phase.

Advantageously, the composition according to the present invention comprising said phyllosilicate, has a diffraction ray aux. X-rays greater than 9.4 Å and less than or equal to 9.8 Å.

Advantageously, the composition according to the present invention comprising said phyllosilicate has an infrared absorption band at 7200 cm ^-1 corresponding to the stretching vibration attributed to the Si-OH silanol groups at the edges of the phyllosilicate layers.

The composition according to the present invention comprising said phyllosilicate, also preferably has an infrared absorption band at 7184 cm- ¹ corresponding to the stretching vibration 2 v Mg ₃ OH.

It should be noted that in the presence of adsorbed water, for example residual, a broad infrared absorption band is detectable, easily identifiable, for example 5500cm ^'1 .

According to a first variant, said synthetic phyllosilicate is used in the form of an aqueous or aqueous-alcoholic gel.

According to a second variant, said synthetic phyllosilicate is used in a dry particulate form (or powder). According to a third variant, said synthetic phyllosilicate is used in the form of an aqueous or aqueous-alcoholic gel and in a dry particulate form (or powder).

According to an alternative embodiment, the composition according to the invention is a cosmetic or dermatological composition comprising a physiologically acceptable medium.

Synthetic phyllosilicates, such as those described in application WO2008 / 009799 and advantageously those disclosed in patent application FR2977580, are particularly suitable for the invention.

However, none of these documents WÔ2008 / 009799 and FÏL29775 0 considers the recovery of synthetic phyllosilicates thus obtained in compositions and in particular for purposes of cosmetic, dermatological or pharmaceutical application.

In particular, none of these documents consider association between these synthetic phyllosilicates and polyols or polyol derivatives and / or UV filters.

As is apparent from the examples below, the combination considered according to the invention is particularly advantageous for (i) reducing the tackiness effect, and (ii) increasing the moisturizing effect of compositions, especially cosmetic compositions, in particular compositions for topical application, comprising polyols and / or polyol derivatives.

Indeed, in general, the introduction of a synthetic phyllosilicate suitable for the invention, in the form of a gel and / or a powder, into a formula containing at least one polyol and / or polyol emulsifier makes it possible to reduce the feeling of stickiness of the emulsion and to have a better feeling of penetration of the formula during the application. The compositions according to the invention slip less than a placebo formula, that is to say a formula not comprising synthetic phyllosilicate suitable for the invention.

The feeling of penetration is directly correlated to the feeling of hydration, so to the perception of effectiveness of the product. The compositions according to the invention also have a clean-skin finish.

The subject of the invention is also the cosmetic use, of a composition as defined above, for the care of the skin and / or the nails by the topical route, in particular for the care of the skin of the body and / or or face, and / or nails. According to another aspect, the subject of the invention is a cosmetic treatment method, comprising the application on the skin and / or the nails by a topical route of a composition of the invention.

According to another aspect, the invention relates to the use of a synthetic phyllosilicate of molecular formula Mg ₃ Si ₄ O ₁₀ (OH) 2 as defined below, in a composition comprising at least one polyol or a polyol derivative. to reduce the sticky effect of said composition.

According to another aspect, the invention therefore also relates to the use of a synthetic phyllosilicate of molecular formula Mg 3 SiO (OH) 2 as defined below, in a composition comprising at least one polyol or a polyol derivative, to increase the moisturizing effect of said composition.

The technical effect observed by the implementation of this combination is also particularly advantageous with regard to compositions comprising said polyols and / or derivatives.

The technical effect observed by the implementation of this combination is also particularly advantageous with regard to compositions comprising high levels of said polyols and / or derivatives, and more particularly comprising high levels of glycols.

"High levels" of these polyols and / or derivatives, preferably of these glycols, include in particular compositions comprising at least 20% by weight, at least 30% by weight of said polyol (s), preferably said glycols, by relative to the total weight of the composition.

In addition, as is apparent from the examples below, the inventors have found that the combination of a synthetic phyllosilicate such as defined below, described in FR 2 977 580, with at least one UV filter as defined herein. below gives access to anti-UV compositions with improved sensory qualities and reduced tackiness, oily and coarse effect of UV filters, and even performance SPF (Sun Protection Factor) improved and / or even stability.

By "SPF" within the meaning of the invention is meant the sun protection factor, which measures the level of protection against UVB. The SPF value is the ratio of the minimum duration of sunburn to an antisolar composition to the one without a product. It is expressed mathematically by the ratio of the dose of UV radiation necessary to reach the erythematogenic threshold with the UV filter on the dose of UV radiation necessary to reach the erythematogenic threshold without UV filter. This factor therefore concerns the effectiveness of the protection whose biological spectrum of action is mainly centered in the UVB and consequently, accounts for the protection with respect to this UV-B radiation.

It also relates to a cosmetic process for limiting the darkening of the skin and / or nails and / or improving the color and / or the uniformity of the complexion, including the application to the surface of the skin and / or the nails. at least one composition as defined above, said composition comprising at least one UV filter.

The composition according to the invention is suitable for topical application.

SYNTHETIC PHYLLOSILICATE

The synthetic phyllosilicate according to the invention has a crystalline structure in accordance with that of a hydroxylated magnesium silicate of molecular formula M 3 SiO (OH) 2 belonging to the chemical family of phyllosilicates.

These phyllosilicates are generally constituted by a stack of elementary sheets of crystalline structure, the number of which varies from a few imitates to a few tens of units. Each elemental sheet is constituted by the association of two layers of tetrahedra, in which are positioned the silicon atoms, located on either side of a layer of octahedra in which the magnesium atoms are positioned. This group corresponds to phyllosilicates 2/1, also called type T .0.T. (tetrahedron-octahedron-tetrahedron).

As explained above, a synthetic phyllosilicate according to the invention can be obtained according to a preparation method such as that described in the application WO2008 / 009799 and is preferably obtained according to the technology described in application FR 2 977 580. This preparation process notably comprises a prolonged hydro-thermal treatment, which makes it possible to obtain an aqueous gel of synthetic phyllosilicate. Thus, according to a first variant embodiment, the synthetic phyllosilicate can be implemented in the form of an aqueous or aqueous-alcoholic gel, in particular in the image of that directly obtained at the end of the synthesis process.

As described in application FR 2 977 580, the parameters which influence the synthesis and the properties of a synthetic phyllosilicate in the form of a gel which are suitable for the invention are the nature of the heat treatment (200 ° C. to 900 ° C.), the pressure, the nature of the reagents and their proportions.

More particularly, the duration and the temperature of the hydro-thermal treatment make it possible to control the size of the particles. For example, the lower the temperature, the smaller the synthesized particles as described in application FR 2 977 580. The size control makes it possible to provide new properties and better control of its hydrophilic and hydrophobic properties. , that is, amphiphilic.

It should be noted, however, that the gel as obtained at the end of the synthesis process may be subjected to a possible washing step with water / centrifugation, after which it is dried and crushed. The synthetic phyllosilicate is then available in powder form.

Thus, the synthetic phyllosilicate considered according to the invention can also be formulated as a powder in a composition according to the invention.

Analysis and structural characterization of a synthetic phyllosilicate suitable for the invention

A synthetic phyllosilicate suitable for the invention can be characterized by various parameters, namely infrared absorption bands, its size, its purity, as detailed below.

Under certain conditions, analyzes such as nuclear magnetic resonance, in particular ²⁹ Si may be useful for the characterization of a synthetic phyllosilicate suitable for the invention. Similarly, thermogravimetric analysis (ATG) can be implemented for the characterization of a synthetic phyllosilicate suitable for the invention. Finally, X-ray diffraction can also be used for this purpose. Infrared

Method used

The apparatus used is a Nicolet 6700 FTIR spectrometer with Fourier transform, equipped with an integrating sphere, with an InGaA detector and a CaF ₂ separator and resolution of 12 cm- ⁵ , more preferably 8 cm- ^1, and even more preferably 4 cm ^{-1, that is to} say the values of the infrared absorption bands given in this description are to be considered as being at plus or minus 6 cm ^-1 and more preferably at plus or minus 4 cm ^-1 and even more preferentially to plus or minus 2 cm ^"1 .

Near-infrared recordings of the elongation region at 7184 cm- ¹ were decomposed by Pseudo-Voigts using Fityk software (Wojdyr, 2010).

To visualize the absorption spectrum in a composition comprising at least one aqueous part, such as an emulsion, it is recommended to heat this composition to a temperature corresponding to a temperature greater than or equal to 100 ° C. (for example 120 ° C. ) and less than or equal to 500 ° C (for example 400 ° C) in order to eliminate the adsorbed water part and possibly some or all of the organic compound (s) present in the composition.

Generally to confirm an infrared absorption band, the skilled person makes stretching enlargements, in particular, the latter can for example make such enlargements to plus or minus 200 cm ^-1 on either side of a suspected infrared absorption band.

A natural talc is a mineral species composed of doubly hydroxylated magnesium silicate of formula Mg ₃ Si40i o (OH) 2, which may contain traces of nickel, iron, aluminum, calcium or sodium.

Natural talc exhibits an infrared spectrum having a typical infrared absorption band, fine and intense, of 7184 cm ^-1 corresponding to the stretching vibration 2 v Mg ₃ OH The natural talc usually has chemical elements substituting for magnesium and to silicon in the crystalline structure which impose the appearance of at least one additional infrared absorption band, in particular that corresponding to the extensional vibration of 7156 cm ^-1 attributable to 2 v Mg 2 FeOH. The spectrum of the synthetic phyllosilicate that is suitable for the invention differs from a natural talc by an infrared absorption band of 7200 cm ^-1 corresponding to the stretching vibration attributed to the Si-OH silanol groups at the edges of the phyllosilicate layers.

To confirm this infrared absorption band, a person skilled in the art can enlarge stretchmg and in particular in the zone of 7400 cm ^-1 - 7000 cm ^-1 , and more particularly in the zone of 7300 cm ^-1 . 7100 cm ^-1 .

Preferably, the spectrum of the synthetic phyllosilicate is also characterized by an absence of a weaker absorption band of 7156 cm ^-1 This 7156 cm ^{-1 band} corresponds to the vibration band of Mg ₂ FeOH.

Preferably, the spectrum of synthetic phyllosilicate is also characterized by the infrared absorption band of 7184 cm ^-1 common to natural talc.

It should be noted that in the presence of adsorbed water, for example residual, a broad infrared absorption band is detectable, easily identifiable, for example 5500cm ⁴ .

Advantageously, the composition according to the present invention comprising said phyllosilicate, is characterized by an absence of an infrared absorption band of 7156 cm ^-1 This band at 7156 cm ^-1 corresponds to the vibration band of Mg ₂ FeOH.

The composition according to the present invention comprising said phyllosilicate. also preferably has an infrared absorption band at 7184 cm- ¹ corresponding to the stretching vibration Mg30H.

In a composition according to the invention, it should be noted that in the presence of adsorbed water, for example residual, a wide infrared absorption band is detectable, easily identifiable, for example 5500cm- ¹ .

Method used In order to perform the particle size analysis of synthetic phyllosilicates suitable for the invention, photon correlation spectroscopy was used. This analytical technique provides access to particle size based on the principle of dynamic scattering of light. This device measures, over time, the intensity of the light scattered by the particles at a given angle Θ and the scattered rays are then processed by the Padé-Laplace algorithm.

This technique, non-destructive, requires a dissolution of the particles. The particle size measurement obtained by this technique corresponds to the value of the hydrodynamic diameter of the particle, that is to say that it comprises both the size of the particle but also the thickness of the hydration layer.

The analyzes were carried out using a VASCO-2 granulometer from Cordouan. In order to obtain statistical information on the distribution of particles, the NanoQ ™ software was used in multi-acquisition mode with the Padé-Laplace algorithm.

Thus, a synthetic phyllosilicate suitable for the invention, when in the form of aqueous or aqueous-alcoholic gel, advantageously has an average size ranging from 300 nm to 500 nm.

In contrast, a synthetic phyllosilicate when it is used in the form of a powder, like that obtained by dehydration of an aqueous gel, as defined above, may have an average size ranging from a few microns to several hundred microns, preferably ranging from 5 μηι to 100 μπι, or may be in the form of porous micron or plurimicron aggregates composed of said particles.

These characteristics are advantageous vis-à-vis a natural talc which one of the constraints is the uncontrolled dimension of its particles.

Purity

The synthetic phyllosilicate considered according to the invention has a degree of purity of at least 99.90%, preferably at least 99.99%.

It is thus advantageously devoid of impurities or undesirable compounds including asbestos such as asbestos (serpentine), chlorite, carbonates, heavy metals, iron sulphides, etc. which are generally associated with natural talc and / or incorporated into the structure of natural talc. NM (Nuclear Magnetic Resonance)

Methods used

The 29 silicon ( ²⁹ Si) NMR spectra were recorded on a BRUKER Avance 400 (9.4 T) spectrometer. The reference for chemical shifts is tetramethylsilane (TMS). The samples were placed in 4 mm zirconia rotors. The rotation speed around the magic angle (MAS) was set at 8kHz. The experiments were performed at room temperature of 21 ° C.

The ²⁹ Si spectra were obtained either by direct polarization (rotation of 30 °) with a recycling time of 60 s or by cross polarization (CP) between 1H and ²⁹ Si (recycling time of 5 s and contact time of 3 ms).

In silicon NMR ( ²⁹ Si), natural talc has a single peak at -97 ppm. In silicon NMR ( ²⁹ Si), unlike natural talc, the spectrum of synthetic phyllosilicate according to the invention reveals two peaks: one located at -95 ppm and the other located at -97 ppm, and without the need for particle size fractionation to less than 500nm. ATG (thermogravimtric analysis)

Method used

The recordings were made using a Perkin Elmer thermobalance

Diamonds.

For each analysis, approximately 20 mg of sample was required. During the analysis, the sample is subjected to a temperature rise from 30 ° C to 1200 ° C with a step of 10 ° C.rain ^" 'under a flow of 100 ^{ml.min" 1} Air .

Thermogravimetric analysis of a synthetic phyllosilicate according to the invention shows a lower thermal stability (around 800 ° C.) than that of natural talc and it is characterized by four losses of mass unlike natural talc which has none only one, around 900 ° C.

To establish these losses of masses, it is useful to refer to the article Angela Dumas, François Martin, Christophe Le Roux, Pierre Micoud, Sabine Petit, Eric Ferrage, Jocelyne Brendle, Olivier Grauby, Mike Greenhill-Hooper "Phyllosilicates synthesis: a way of accessing edges in NMR and FTIR spectroscopies.

It should be noted that a synthetic phyllosilicate according to the invention is devoid of interfoliary cations. Indeed, this characteristic is demonstrated by the absence of an X-ray diffraction line located at a distance of between 12.00 Å and 18.00 Å, usually revealing a swelling phase with interfoliary spaces in which there are interfoliary cations and possible water molecules.

A synthetic phyllosilicate suitable for the invention may be present in an amount ranging from 0.01% to 20% by weight, preferably ranging from 0.1% to 15% by weight, more preferably ranging from 0.1% to 1% by weight. 1% by weight, still more preferably ranging from 0.5% to 11% by weight, better still from 0.5% to 7% by weight, better still from 1% to 6% by weight, and even better ranging from 2% by weight % to 5% by weight relative to the total weight of the composition.

Carbohydrate of the family of oses, or oligosides, or homopolyholosides Carbohydrate is any organic molecule containing a carbonyl group (aldehyde or ketone) and several hydroxyl groups (-OH). Carbohydrates were historically called carbohydrates or carbohydrates. Their chemical formula is based on the model C _n (H20) _p (hence the historical name). However, this model is not suitable for all carbohydrates, some of which contain heteroatoms such as nitrogen or phosphorus.

Carbohydrates usually include:

(1) monosaccharides or oses that are simple, non-hydrolyzable molecules forming crystals. They are of two types: (a) aldoses comprising an aldehyde function on the first carbon and ketoses comprising a ketone function on the second carbon. They are also distinguished according to the number of carbon atoms they possess.

(2) Oligosaccharides or oligosides which are osteoside polymers having a chain of monosaccharides comprising from 2 to 10 monosaccharide units united by glycosidic linkages.

(3) polyholosides (polysaccharides) which are osteoside polymers having a chain of monosaccharides greater than 10 units (eg amylose, amylopectin, cellulose, glycogen).

Among the oligosides and polyosides, one. distinguishes:

homopolyosides are the carbohydrates whose hydrolysis gives a single type of risk. - Heterosides and heteropolyosides are carbohydrates whose hydrolysis does not give a single type of risk. These are polymers of oste and non-carbohydrate molecule (s). As an example of a heteroside, mention may be made of salicyline.

The invention relates to carbohydrates of the family of:

- monosaccharides or oses,

oligosaccharides or oligosides,

polysaccharides of the homopolyholoside type.

(1) The oses

Among the monosaccharides or monosaccharides that can be used according to the invention, mention may be made of:

trioses having 3 carbons: dihydroxyacetone, glyceraldehyde;

- 4-carbon tetroses: erythrosis, threose, erythralosis;

pentoses having 5 carbons: ribose, arabinose, xylose, lyxose, ribulose, xylulose, deoxyribose;

hexoses having 6 carbons: allose, altrose, glucose, mannose, fucose, gulose, idose, galactose, talose, fuculose, psicose, fructose, sorbose, tagatose, quinovose, pneumose, rhamnose;

heptoses having 7 carbons: sedoheptulose, glucoheptose, idoheptulose, marmoheptulose, taloheptulose;

octoses having 8 carbons;

- Ooses with more than 8 carbons such as maltitol;

in their D or L form.

Among these, more preferably trehalose and / or hexoses, and more particularly glucose, mannose, rhamnose, and fucose will be used.

Mention may also be made of their derivatives, in particular alkyl derivatives, such as methylated derivatives such as methylglucose, as well as compounds containing one or more sugars, and mixtures thereof. As a compound containing a sugar or a mixture of sugars, mention may be made of natural compounds such as honey, and polymers such as, for example, the product sold under the name "fucogel 1000" by the company Solabia (CTFA name Biosaccharide gum-1), polymer containing fucose, galactose and galacturonic acid. (2) Oligosaccharides

Among the oligosaccharides that may be used according to the invention, mention may be made of:

(i) disaccharides or diholosides or diosides composed of two molecules of oste and which may be reducing or non-reducing. The term "non-reducing disaccharide" any disaccharide, the carbon 1 carrying the hemiacetal OH is engaged in a bond, ie the hemiacetal function is not free. The term "disaccharide reducer" any disaccharide therefore the hemiacetal function is free.

Among the non-reducing disaccharides, mention may be made of sucrose and trehalose. Among the reducing disaccharides, mention may be made of lactose, maltose, cellobiose, isomaltose and meiotomy.

(ii) triholosides composed of three molecules of oste, such as raffmose, gentianose, melezitose.

(iii) dextrins and cyclodextrins which are mixtures of linear gluco-oligosaccharides (glucose oligosides), the glucose units of which are linked by α- (1,4) - type osidic bonds, but whose grouping is linked by an α- (1,6) osidic bond.

(3) Homopolysaccharides or homoglucans

Among the polysaccharides or polyholosides, homopolysaccharides (or homoglycans) consisting of the same monosaccharide are considered here: fructans, glucans, galactans, mannan, for example; can be linear, branched or mixed.

For example:

homopolymers of fructan, for example tinuline, which is a polyholoside composed of fructose units linked by a β (2 → 1) bond; the fructose chain ending in α-D-glucose;

homopolymers of glucan whose starches, for example, which are non-reducing homogeneous polyholosides consisting of two compounds: amylose (water-soluble), a glucose polymer bound by an α (1 → 4) bond (20 to 30%) , and amylopectin (insoluble), branched amylose via a (1 → 6) bond (70 to 80%). We can also mention glycogen, which at structure level is almost identical to starch: it has more ramifications than starch (one branch every 10 glucose residues), the rest of the structure is identical to starch . Its molar mass is higher (of the order of 106 g / mol). Cellulose, too, which is a polyholoside homogeneous glucose linked by a β bond (1 → 4). Or, dextrans which are compounds of D-glucose units linked by a saccharide bond a (1 → 6).

homopolymers of galactan including agar-agar, for example, which is a mixed polyholoside consisting of D- and L-galactose esterified with sulfuric acid. or carrageenans.

or homopolymers of xylose (xylanes) or of mannose (Mannanes).

According to a particular embodiment of the invention, the compounds chosen from the sugars and their derivatives are chosen from sucrose esters, glucose esters, glucose ethers, rhamnose, mannose, trehalose, fucose.

The emulsifiers derived from sugar are chosen from:

esters of sucrose or glucose and of fatty acid (for example, sucrose palmitostearate).

WATER QSP QSP QSP QSP Results:

It turns out that the composition D outside the invention, without glycol, is not very tacky. On the other hand, when the composition comprises 30% glycol (composition B outside the invention), it becomes very strongly tacky. Thus, glycols induce a very intense stickiness sensation.

In addition, by comparing the composition A according to the invention with the composition B outside the invention, it appears that a synthetic phyllosilicate gel form suitable for the invention can reduce the tacky effect provided by glycols compared to the POLYACRYLOYLDIMETHYL TAURATE AMMONIUM (AMPS).

Finally, the comparison between the composition A according to the invention and the composition C outside the invention makes it possible to demonstrate that the cosmetic properties of these two compositions are very close, with or without a large amount of glycols (30% by weight).

These data demonstrate the ability of a synthetic phyllosilicate suitable for the invention to reduce the tackiness of a composition comprising a polyol.
