Description

[Technical Field]

[0001] The present invention relates to a composition for topical use in the form of a gel, comprising water that is at least moderately mineralized, so that it has a conductivity of at least 200 μS / cm measured at 25° C., and which has an efficient thickening system. [Background technology]

[0002] The cosmetics industry uses water of various qualities to prepare cosmetic formulations for sale to end consumers, including natural mineral water, seawater, spring water, terrestrial plant water, and algae water.

[0003] These various waters differ, inter alia, in their geographical and geological origins and, consequently, in their mineralogy. Therefore, water can be characterized by its "total mineralization," i.e., the sum of all mineral elements present in the water under consideration. More specifically, it is a matter of the sum of the amounts of cations and anions present in the water. The cations present in mineral waters are calcium, magnesium, sodium, potassium, iron, zinc, copper, aluminum, and manganese. The anions present in mineral waters are carbonate, bicarbonate, silicate, sulfate, chloride, nitrate, phosphate, and fluoride. Consequently, the concept of "total mineralization" is expressed in units of mass per unit volume, specifically milligrams per liter.

[0004] This mineralization property may be reassessed by measuring the electrical conductivity of said water, which is generally expressed in microsiemens / centimeter (μS / cm) or millisiemens / cm (mS / cm).

[0005] As used herein, the term "low-mineral water" means water having a conductivity of less than 200 μS / cm measured at 25°C.

[0006] As used herein, the term "medium mineral water" means water having a conductivity measured at 25°C of 200 μS / cm or more and less than 333 μS / cm.

[0007] As used herein, the term "Nakagami mineral water" refers to water having a conductivity measured at 25°C of 333 μS / cm or more and less than 666 μS / cm.

[0008] As used herein, the term "high mineral water" refers to water having a conductivity measured at 25°C of 666 μS / cm or more and less than 1000 μS / cm.

[0009] As used herein, the term "highly mineralized water" means water having a conductivity of 1000 μS / cm or greater measured at 25°C.

[0010] Natural mineral waters, seawater, natural spring waters and algal waters are characterized by at least moderate mineralization, i.e., a conductivity of 200 μS / cm or more measured at 25° C., and are often used for the preparation of cosmetic, dermocosmetic, pharmaceutical and dermopharmaceutical compositions for the properties they can provide to human or animal skin.

[0011] Indeed, natural waters, mineral waters, seawater, and algae waters with medium to high mineral content are known to contribute antioxidant, soothing or anti-inflammatory, and allergy-inhibiting properties. It is known in the literature that mineral water is used in formulations to reduce the loss of elasticity of human skin. EP 1170002 A1 describes a method for reducing the loss of elasticity of human skin, including the use of mineral water containing a mineral concentration of at least 200 mg / L. Similarly, EP 0699432 A1 describes the use of water with a total mineralization of 700 mg / L or more to relieve skin irritation that may be caused by active agents such as retinoids, benzoyl peroxide, or salicylic acid used in the treatment of acne.

[0012] It is also known that algae water or seawater can be used for the care of skin disorders such as eczema and psoriasis, or to re-establish health after musculotendinous injuries or conditions or sprains.

[0013] Therefore, there is a demonstrated need to carry out long-term topical applications of seawater or algal water, in the presence or absence of biologically active or inactive components, in order to better target the relevant human or animal body zones.

[0014] JP 2000-273033 A describes a composition in the form of a gel containing an active ingredient and a combination of trehalose and carrageenan as gelling agents.

[0015] EP 2756839 describes a composition based on 95% by weight seawater and hydroxyethylmethylcellulose as gelling agent.

[0016] However, these solutions do not allow the preparation of topically acceptable compositions in the form of gels having high viscosities, e.g., 10,000 mPa·s or more (measured at 25° C. with a Brookfield RVT viscometer at speed 5).

[0017] Cosmetic compositions in the form of aqueous gels marketed by the cosmetic and pharmaceutical industries usually contain synthetic thickening polymers to increase the viscosity of the solution so as to obtain a gel that is applied directly or indirectly to the skin.

[0018] The synthetic thickening polymers currently used in these fields are available in two physical forms: powder and liquid. The polymers are prepared by inverse emulsion radical polymerization using surfactants, and are commonly referred to as self-inverting inverse latexes.

[0019] The most commonly known synthetic thickening polymers in powder form include polymers based on acrylic acid or copolymers based on acrylic acid and its esters. For example, Carbopol TM and Pemulen TM Examples of suitable polymers include those sold under the trade name CI 10 ...

[0020] In cosmetics, homopolymers or copolymers based on 2-acrylamido-2-methylpropanesulfonic acid and / or its salts are still used in powder form. These thickening polymers are also used in the Aristoflex TM These powdered synthetic thickeners are sold under the trade name EP 816403, EP 1116733 and EP 1069142. These powdered synthetic thickeners are obtained by precipitating the polymerization; the monomers are dissolved in an organic solvent such as benzene, ethyl acetate, cyclohexane or tert-butanol; therefore, this process is used to remove traces of residual solvent. Therefore, multiple successive steps are required for purification of the final product.

[0021] The cosmetic and pharmaceutical industries also make very widespread use of thickeners in the liquid form of self-inverting inverse latex, in particular those sold by the applicant, for example the thickener Sepigel TM 305, Simulgel TM 600, Simulgel TM EG, Simulgel TM EPG, Simulgel TM N.S., Simulgel TM A, Sepiplus TM 400, Sepiplus TM 250 and SepiplusTM 265. These thickeners are obtained by inverse emulsion radical polymerization. They have the advantage of being more easily manipulated, especially at room temperature, and dispersing very quickly in water. Furthermore, these products exhibit significantly higher thickening properties; this is likely a result of the process used to prepare them: dispersed-phase radical polymerization, which results in polymers with very high molecular weights.

[0022] The applicant has also developed synthetic thickeners that have thickening qualities comparable to or superior to those of inverse latex, but are better tolerated by the skin, particularly due to the absence of an oil phase, which can result in lighter-colored aqueous gels. These products are in powder form but have dissolution times and, therefore, ease of application comparable to those of liquid-form products. These compounds, described in EP 1 496 081 A1, are obtained via conventional polymerization techniques, such as dispersed-phase radical polymerization, inverse suspension radical polymerization, and inverse emulsion or inverse microemulsion radical polymerization. The resulting synthetic thickening systems are then extracted and purified by various techniques, such as precipitation from an intermediate solvent, followed by optional washing, spray drying, or azeotropic dehydration, and optionally washing with a solvent. These synthetic thickeners thus combine the advantages of synthetic thickeners in standard powder form (absence of oil, production of lighter-colored aqueous gels) with those in inverse latex form (high dissolution rate, significant thickening power, and stabilizing properties). Summary of the Invention [Problem to be solved by the invention]

[0023] However, synthetic thickening polymers such as the cross-linked anionic polyelectrolytes mentioned above are not expected to be sufficiently efficient for use in the presence of water that is at least moderately mineralized and, as a result, has a conductivity of 200 μS / cm or more measured at 25°C.

[0024] Therefore, there remains a need for compositions for topical use that are in the form of gels containing water that are at least moderately mineralized, resulting in a conductivity of at least 200 μS / cm measured at 25° C., and for efficient thickening systems, i.e., systems that make it possible to achieve particularly high viscosity levels for topical use on human or animal skin in the presence of biologically active agents. [Means for solving the problem]

[0025] One solution of the present invention is a composition (C1) for topical use in the form of a gel, comprising: - Conductivity measured at 25°C is 300 microsiemens / centimeter (μS cm -1 ) or more - Crosslinked anionic polyelectrolyte (P1) and - at least one galactomannan (GM).

[0026] As used herein, the term "gel" refers to a chemical composition that is initially in liquid form and that, after the addition of a gelling and / or thickening agent, is transformed into a non-flowing structural state. A gel, as defined, is considered an intermediate state between the solid and liquid states and consists of a three-dimensional network within a liquid as a result of chemical or physical bonds.

[0027] For purposes of the present invention, the term "gelling agent" means a compound or mixture of compounds that converts a liquid medium into a gel.

[0028] For the purposes of the present invention, the term "thickener" means a compound or mixture of compounds that increases the viscosity of the medium into which it is introduced.

[0029] The term "for topical use" as used in the definition of the composition for topical use (C1) as described above means that the composition is used by application to the skin, hair, scalp, nails, lips, mucous membranes, eyelashes or eyebrows, whether this is direct or indirect application in the case of cosmetic preparations, for example in the case of body care products in the form of textile or paper wipes, or hygiene products intended to come into contact with the skin, hair, scalp, nails, lips, mucous membranes, eyelashes or eyebrows.

[0030] The conductivity of the aqueous phase (A1) is measured by directly measuring the current flowing between two electrodes immersed in the aqueous phase (A1) to be measured at a temperature of 25° C. The injected current is an alternating current of very low frequency to avoid polarization of the electrodes.

[0031] The device used consists of a collection box and a probe, which is made up of a temperature electrode, a measuring electrode consisting of two or more sensors or grouped electrode devices.

[0032] The device used is more particularly a WTW brand device, model pH / Cond 34Oi. The measurements are expressed in μS / cm at reference temperature (25° C.).

[0033] The subject of the present invention is 300 μS·cm measured at 25 °C. -1 The aqueous phase (A1) present in the composition (C1) for topical use characterized by a conductivity equal to or greater than this may originate from natural sources and may be used alone or in a mixture with water of another origin.

[0034] present in the composition (C1) for topical use that is the subject of the present invention, and having a conductivity of 300 μS cm, measured at 25 °C -1 The aqueous phase (A1) characterized as described above preferably consists of natural mineral water, natural water, seawater, or algae water.

[0035] Also present in the composition (C1) for topical use that is the subject of the present invention, and having a conductivity measured at 25 ° C of 300 μS cm-1 The aqueous phase (A1) characterized as above may be prepared by mixing natural mineral water, natural water, seawater or algae water with demineralized water to adjust the selected conductivity.

[0036] For the purposes of this invention, the term "natural mineral water" means water in which the content of trace elements is stable, which is suitable for consumption, and whose "total mineralization" meets the requirements of the definition in Article 1322, paragraph 2 of the French Public Health Code, or more generally, meets the provisions of Articles L.1322-1 to L.1322-13, R.1322-1 to R.1322-44-8, and R.1322-45 to R.1322-67 of the French Public Health Code.

[0037] For the purposes of the present invention, "natural mineral water" means a natural mineral water as defined above, used for therapeutic purposes and having received prior authorization from the French prefectural authorities after a directive from the local health authority.

[0038] Examples of natural or mineral waters that can be combined with the aqueous phase (A1) present in the composition (C1) according to the invention are Avens water, Vittel, Witch basin water, Woolridge water, Roche-Posay water, Bourbourg water, Enghien-les-Bains water, Saint-Gervais-les-Bains water, Néris-les-Bains water, Albard-les-Bains water, Digne water, Maisiere water, Neyrac-les-Bains water, Lons-les-Sonia water, Rochefort water, Saint-Christo water, Humades water, Tahsis-les-Bains water, Bagneret-de-Bigolès water, Eugène-les-Bains water, Charles-le-Haut water, Volvic water, Vals water, These include Verney, Aix-les-Bains, Areto, Abatile, Arsene, Arby, Asperjoc, Badois, Silao, Contrex, Evian, Epar, Jouvance, Montlucas, Houju, Oletza, Palo, Perrier, Plancoet, Quezac, Rosana, St. Alban, St. Iamand-les-Hauts, Saint-Georges, Saint-Igueron, Saint-Marguerite, Saint-Illeol, Salveta, Tessieres-les-Bries, Thonon, Treignac, Courmayeur, San Benedetto, and San Pellegrino.

[0039] For purposes of the present invention, the term "algal water" refers to water collected by evaporation and condensation of water contained in harvested algae, said water being derived from the algal cells thus treated. According to specific embodiments, it is water derived from brown algae, red algae, or green algae. According to even more specific embodiments, it is water derived from Laminaria digitata, Chondrus crispus, or Gigartina stellata.

[0040] Examples of algae waters that can be combined with the aqueous phase (A1) present in the composition (C1) according to the invention include Hydralixir TM LD or Hydralixir TM An example is algae water sold under the trade name CC.

[0041] For the purposes of the present invention, the term "galactomannan (GM)" refers to a polysaccharide consisting solely of monosaccharides (or polysaccharides), that is, a polymer whose backbone consists of D-mannose units linked by β-1,4 bonds and to which D-galactose units are grafted along the sides via α-1,6 bonds.

[0042] Polysaccharides are sugar polymers. The IUPAC definition of saccharide refers to monosaccharides, compounds of the monosaccharide itself and their derivatives, obtained by reduction of a carbonyl group, or oxidation of one or more hydroxyl groups, or replacement of one or more hydroxyl groups with hydrogen atoms, amine groups, phosphate groups, or sulfate groups.

[0043] The polysaccharides most commonly used to prepare food, cosmetic, or pharmaceutical compositions consist primarily of monosaccharides such as glucose, galactose, and mannose, or monosaccharide derivatives in which the terminal hydroxyl groups have been oxidized to carboxyl groups. As a result, there are two distinct groups of polysaccharides: those consisting only of monosaccharides (or polymonosaccharides) and those consisting of monosaccharide derivatives. Among the polysaccharides consisting only of monosaccharides, the following can be distinguished: Glucan, a glucose homopolymer that is extremely abundant in nature, Glucomannoglycans, xyloglycans, Galactomannan, a polymer whose main chain consists of D-mannose units linked by β-1,4 bonds and to which D-galactose units are grafted along the sides by α-1,6 bonds.

[0044] Galactomannans are found in several plant species, particularly legumes, which make up the albumen of their seeds.

[0045] Depending on the botanical origin of the galactomannan source, the degree of substitution (DS) of D-galactose units on the D-mannose backbone ranges from 0 to 1: Galactomannans derived from cassia gum have a degree of substitution (DS) of approximately 1 / 5, which means that for every five D-mannose units present on the polysaccharide backbone, one D-galactose unit is grafted along the side; Galactomannans derived from locust bean gum have a degree of substitution (DS) of approximately 1 / 4, which means that for every four D-mannose units present on the polysaccharide backbone, one D-galactose unit is grafted along the side; Galactomannans derived from tara gum have a degree of substitution (DS) of approximately 1 / 3, which means that for every three D-mannose units present on the polysaccharide backbone, one D-galactose unit is grafted along the side; Galactomannans derived from guar gum have a degree of substitution (DS) of approximately 1 / 2, which means that for every two D-mannose units present on the polysaccharide backbone, one D-galactose unit is grafted along the side; Galactomannans derived from fenagle gum have a degree of substitution (DS) of approximately 1 / 1, which means that virtually every D-mannose unit present on the polysaccharide backbone has one D-galactose unit grafted along the side.

[0046] Thus, in the compositions of the present invention, the galactomannan (GM) is selected from the group consisting of galactomannans with a degree of substitution (DS) of about 1 / 3, galactomannans with a degree of substitution (DS) of about 1 / 2, and galactomannans with a degree of substitution (DS) of about 1 / 4.

[0047] In the definition of the composition for topical use (C1) that is the subject of the present invention, the term "crosslinked anionic polyelectrolyte (P1)" means a non-linear crosslinked anionic polyelectrolyte, which is in the form of a three-dimensional network that is insoluble in water but swellable in water, resulting in the formation of a chemical gel.

[0048] In some cases, the compositions of the present invention may have one or more of the following characteristics: - per 100% by weight of the composition, 93 to 99.4% by weight, preferably 95 to 99.3% by weight, more preferably 95.5 to 99.0% by weight, even more preferably 95.5 to 99.0% by weight of the composition has a conductivity of 300 microsiemens / cm (or μS·cm) measured at 25°C -1 ) or more, 0.5 to 5% by mass, preferably 0.5 to 3% by mass, and even more preferably 0.5 to 2.5% by mass of a crosslinked anionic polyelectrolyte (P1), and 0.1 to 2% by mass, preferably 0.2 to 2% by mass, and even more preferably 0.5 to 2% by mass of a galactomannan (GM); - The degree of substitution of the galactomannan is 1 / 3; - the crosslinked anionic polyelectrolyte (P1) comprises monomer units derived from 2-methyl-2[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid in free acid or partially or totally salified form. For the purposes of the present invention, the term "salinated" means that the acid groups present in the monomer are converted to cations, in particular alkali metal salts (for example sodium or potassium ions), nitrogen bases (for example ammonium salts, lysine salts or monoethanolamine salts (HOCH2-CH2-NH3 + )) in the form of an anion bonded to a cation in the form of a salt, such as, for example, sodium or ammonium salts; - the crosslinked anionic polyelectrolyte (P1) is composed of monomer units derived from at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, 2-carboxyethylacrylic acid, itaconic acid, maleic acid and 3-methyl-3-[(1-oxo-2-propenyl)amino]butanoic acid, the carboxyl groups of which are in the free acid or partially or totally salified form; and at least one monomer unit derived from a polyethylenic crosslinking monomer (AR); - the crosslinked anionic polyelectrolyte (P1) consists of monomer units derived from acrylic acid and at least one monomer unit derived from a polyethylenic crosslinking monomer (AR); the polyethylenic crosslinking monomer (AR) is selected from the group consisting of methylenebis(acrylamide), ethylene glycol dimethacrylate, diethylene glycol diacrylate, ethylene glycol diacrylate, diallyl urea, triallylamine, trimethylolpropane triacrylate, diallyloxyacetic acid or a salt thereof such as sodium diallyloxyacetate, or a mixture of these compounds; - the polyethylenic crosslinking monomer (AR) is triallylamine, trimethylolpropane triacrylate or methylenebis(acrylamide), or a mixture of these compounds; - the crosslinked anionic polyelectrolyte (P1) is a copolymer of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid (γ), partially or totally salified in the form of its sodium salt, crosslinked with triallylamine and / or methylenebis(acrylamide), and acrylic acid (δ), partially or totally salified in the form of its sodium salt, the molar ratio (γ) / (δ) being greater than or equal to 40 / 60 and less than or equal to 90 / 10; a copolymer of 2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid (γ) and hydroxyethyl acrylate (ζ) in which the molar ratio (γ) / (ζ) is 30 / 70 or more and 90 / 10 or less; a copolymer of 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid (γ) partially or completely salified in the form of a sodium salt, crosslinked with triallylamine and / or methylenebis(acrylamide), and acrylamide (ε) in which the molar ratio (γ) / (ε) is 30 / 70 or more and 90 / 10 or less. The mass ratio of galactomannan (GM) to crosslinked anionic polyelectrolyte (P1) is 0.15 to 0.75, preferably 0.20 to 0.60, more preferably 0.25 to 0.60, and even more preferably 0.20 to 0.50.

[0116] The following examples illustrate the present invention but do not limit it in any way.

[0117] Preparation and evaluation of aqueous gels according to the present invention and comparative aqueous gels 1) Preparation of aqueous gel Four aqueous gels according to the present invention, designated (F1) to (F4), and eight comparative aqueous gels, designated (F'1) to (F'8), were prepared by the following method. Their mass ratios and components are summarized in Table 1 below.

[0118] The aqueous phase is prepared by introducing high-conductivity water and demineralized water at 25 °C in a relative ratio that allows obtaining an aqueous phase with the desired conductivity (e.g., 730 μS / cm or 3.28 mS / cm in the experimental section below). Next, the crosslinked anionic polyelectrolyte is gradually introduced into the previously prepared aqueous phase at 25 °C using moderate mechanical stirring, i.e., using an anchor-type stirring head, at a speed of 50 to 150 rpm, until a homogeneous gel is obtained. Galactomannan (GM) is added to the previously formed gel at a temperature of 25 °C while stirring using a mechanical stirrer equipped with an anchor-type stirring head. This stirring is then maintained for 10 minutes; no cooling step is necessary.

[0119] 2) Characterization of aqueous gels The properties of the aqueous gel are: - The appearance of the prepared gel is evaluated and a uniform appearance of the gel is observed at 25°C; and - determination of the dynamic viscosity of gels prepared at 25°C, It is inspected by.

[0120] The results of the characterization and measurements are shown in Table 1 below.

[0121] [Table 1]

[0122] [Table 2]

[0123] (1) Hydralixir TMLD (INCI name: water and Laminaria Digitata Extract) is a cell water derived from brown algae, Laminaria Digitata. (2) Solagum TM AX (INCI name: acacia Senegal gum and Xanthan gum) is a thickening and stabilizing agent for preparing cosmetic compositions. (3) Solagum TM Tara (INCI name: Caesalpinia Spinosa Gum) is a galactomannan with a degree of substitution of 1 / 3, used as a thickener and stabilizer for preparing cosmetic compositions. (4) Sepinov TM EMT10 (INCI name: hydroxyethyl acrylic acid / sodium acryloyldimethyl taurate copolymer) is a thickener, stabilizer and emulsifier, used in powder form in the preparation of cosmetic compositions. (5) Simulgel TM EG (INCI name: Sodium Acrylate / Sodium Acryloyldimethyl Taurate Copolymer & Isohexadecane & Polysorbate 80) is a thickener, stabilizer, and emulsifier in the form of a self-inverting inverse latex, and is used to prepare cosmetic compositions. It is used. (6) Sepigel TM 305 (INCI name: Polyacrylamide (and) C13-14 Isoparaffin (and) Laureth-7) is a thickener, stabilizer and emulsifier, in the form of a self-inverting inverse latex, used to prepare cosmetic compositions. ( * ):Simugel TM The EG is in the form of a self-inverting inverse latex with a cross-linked anionic polyelectrolyte content of 40%. ( ** ):Sepigel TM305 is in the form of a self-inverting inverse latex with a cross-linked anionic polyelectrolyte content of 40%.

[0124] 3) Analysis of results 0.5% by weight of tara gum was added to Sepinov TM When used in combination with 1.5% by weight of a cross-linked anionic polyelectrolyte sold under the trade name EM10, a very viscous aqueous gel (F1) (190,000 mPa·s) can be obtained, but the addition of 1.5% by weight of Sepinov TM The aqueous gel of EMT10(F'1) only achieved a viscosity of 48,000 mPa·s.

[0125] When tara gum was replaced with a mixture of acacia gum and xanthan gum, the formation of a high-viscosity aqueous gel was not observed, and the viscosity of the obtained comparative gel (F'2) was 41,100 mPa·s, i.e., Sepinov TM It is very close to the viscosity level of the aqueous gel (F'1) obtained solely with cross-linked anionic polyelectrolyte sold under the trade name EM10.

[0126] The viscosities of the comparative gels (F'3), (F'4) and (F'5) obtained with tara gum alone at various dosages (0.5%, 1% and 1.5%, respectively) showed values ​​of 240 mPa·s, 5000 mPa·s and 41,000 mPa·s, respectively, and therefore, the viscosity of the gels obtained with 0.5% by mass of tara gum and Sepinov TM It does not reflect the viscosity levels achieved in combination with 1.5 wt. % of a cross-linked anionic polyelectrolyte sold under the trade name EM10.

[0127] Such high viscosities are also observed when tara gum is combined with cross-linked anionic polyelectrolytes of different nature, such as cross-linked copolymers based on sodium acrylate and sodium acryloyldimethyltaurate (170,000 mPa·s for aqueous gel (F2) according to the invention) or cross-linked copolymers based on acrylamide and sodium acryloyldimethyltaurate (220,000 mPa·s for aqueous gel (F3) according to the invention).

[0128] Furthermore, when comparing the viscosity of the aqueous gel according to the invention (F4) with that of the comparative aqueous gel (F'8), the synergistic effect of the combination is also demonstrated when the conductivity of the aqueous phase is higher (3.28 mS / cm for (F4) and (F'8)).
