Description

[Technical field]

[0001] The present invention relates to a composition comprising a combination of an electrolyte and a polysaccharide. [Background technology]

[0002] Gelling of compositions containing electrolytes, especially large amounts of electrolytes, makes it difficult to obtain sufficient viscosity effects, and therefore, there are technical challenges in gelling compositions containing electrolytes.

[0003] Some techniques for gelling electrolyte-containing compositions have been reported up to now.For example, WO2014 / 132783 discloses a gel composition for skin, characterized by comprising (A) an electrolyte, (B) a nonionic polysaccharide compound, and (C) a crosslinked polymer formed using (C1) acrylamidomethylpropanesulfonate, (C2) dimethylacrylamide, (C3) alkyl (meth)acrylate, and (C4) polyoxyethylene alkyl ether (meth)acrylate.

[0004] Recently, due to increasing awareness of environmental issues, consumers tend to desire products that use more earth-friendly raw materials.

[0005] Therefore, there is a need to provide a gel-like composition formed from natural resources that has improved applicability, can maintain transparency over time even when it contains a large amount of electrolyte, and has a preferred range of hardness.

[0125] Xanthan is a heteropolysaccharide produced on an industrial scale by aerobic fermentation of gram-negative bacteria of the genus Bacterium. Its structure consists of a backbone of β-D-glucose linked in β(1,4) similar to cellulose. One of every two glucose molecules carries a trisaccharide side chain composed of α-D-mannose, β-D-glucuronic acid and a terminal β-D-mannose. The internal mannose residue is generally acetylated at carbon 6. Approximately 30% of the terminal mannose residues carry a pyruvate group linked in chelate form between carbons 4 and 6. Glucuronic acid and charged pyruvate are ionizable, which is responsible for the anionic character of xanthan (negative charge up to pH 1). The content of pyruvate and acetate residues varies depending on the strain, the fermentation process, post-fermentation conditions and purification steps.

[0126] Xanthan gum has a molecular weight between 1,000,000 and 50,000,000 and a viscosity between 0.6 Pa.s and 1.65 Pa.s for an aqueous composition containing 1% xanthan gum (measured at 25° C. using a Brookfield LVT viscometer at 60 rpm per minute). Xanthan gum is represented, for example, by products sold under the name Rhodicare by Rhodia Chimie, under the name Satiaxane™ by Cargill Texturizing Solutions (for the food, cosmetic and pharmaceutical industries), under the name Novaxan™ by ADM, and under the names Kelzan® and Keltrol® by CP-Kelco.

[0127] Gellan gum is an anionic linear heteropolysaccharide based on oligosaccharide units composed of tetrasaccharides. D-glucose, L-rhamnose and D-glucuronic acid are present in gellan gum in the form of monomeric elements in a ratio of 2 / 1 / 1. It is sold, for example, by the company CP Kelco under the name Kelcogel CG LA.

[0128] Gum arabic is a highly branched acidic polysaccharide that exists in the form of a mixture of potassium, magnesium and calcium salts. The free acid (arabic acid) monomeric elements are D-galactose, L-arabinose, L-rhamnose and D-glucuronic acid.

[0129] Alginic acid, a natural substance derived from brown algae or certain bacteria, is a polyuronic acid composed of two uronic acids, β-D-mannuronic (M) acid and α-L-glucuronic (G) acid, linked by 1,4-glycosidic bonds. Alginic acid is capable of forming water-soluble salts (alginates) with alkali metals such as sodium, potassium or lithium, with lower amines and with ammonium substitution cations, e.g., methylamine, ethanolamine, diethanolamine or triethanolamine.

[0130] Hyaluronic acid has the chemical formula:

[0131] [ka]

[0132] It can be expressed as:

[0133] In the context of the present invention, the term "hyaluronic acid" refers specifically to a compound of the formula:

[0134] [ka]

[0135] It contains the basic unit of hyaluronic acid. It is the smallest portion of hyaluronic acid that contains a disaccharide dimer, namely D-glucuronic acid and N-acetylglucosamine.

[0136] The term "hyaluronic acid and its derivatives" in the context of the present invention also includes linear polymers comprising the above-described polymer units linked together in a chain via alternating β(1,4) and β(1,3) glycosidic bonds, with a molecular weight (MW) that can range between 380 and 1,000,000 daltons, which depends mainly on the source from which the hyaluronic acid is obtained and / or on the preparation method.

[0137] The term "hyaluronic acid and its derivatives" also includes, in the context of the present invention, hyaluronic acid salts. Among the salts that may be mentioned are the alkali metal salts, such as the sodium salt and the potassium salt, the alkaline earth metal salts, such as the magnesium salt, the ammonium salt, and mixtures thereof.

[0138] According to a preferred embodiment of the present invention, the hyaluronic acid fraction suitable for use in the present invention has a molecular weight between 50,000 Da and 5,000,000 Da, in particular between 100,000 Da and 5,000,000 Da, and more particularly between 400,000 Da and 5,000,000 Da, in which case the term used is high molecular weight hyaluronic acid.

[0139] Alternatively, hyaluronic acid fractions that may be suitable for use within the present invention have a molecular weight between 50,000 Da and 400,000 Da, in which case the term used is intermediate molecular weight hyaluronic acid.

[0140] Additionally or alternatively, hyaluronic acid fractions that may be suitable for use within the present invention have a molecular weight of less than 50,000 Da, in which case the term used is low molecular weight hyaluronic acid.

[0141] Pectin is a linear polymer of α-D-galacturonic acid (at least 65%) linked to a specific proportion of carboxylic acid groups esterified with methanol groups in positions 1 and 4. Approximately 20% of the sugars that make up the pectin molecule are neutral sugars (L-rhamnose, D-glucose, D-galactose, L-arabinose, D-xylose). L-rhamnose residues are present in all pectins and are incorporated in positions 1 and 2 into the backbone. Uronic acid molecules carry a carboxyl functional group. This functional group, when they are in the COO-form, gives pectin the ability to exchange ions. Divalent ions (especially calcium) have the ability to form ionic bridges between two carboxyl groups of two different pectin molecules.

[0142] Carrageenans are anionic polysaccharides that constitute the cell walls of various red algae (Rhodophyceae) belonging to the families Gigartinaceae, Hypneaceae, Furcellariaceae and Polyideaceae. They are generally obtained by hot water extraction from natural strains of said algae. These linear polymers formed by disaccharide units consist of two D-galactopyranose units linked alternately through α(1,3) and β(1,4) bonds. They are highly sulfated polysaccharides (20-50%), in which the α-D-galactopyranosyl residues can be in the 3,6-anhydro form. According to the number and position of the ester sulfate groups on the repeating disaccharides of the molecule, several types of carrageenan are distinguished: kappa-carrageenan, which possesses one ester sulfate group, iota-carrageenan, which possesses two ester sulfate groups, and lambda-carrageenan, which possesses three ester sulfate groups. Carrageenan consists essentially of potassium, sodium, magnesium, triethanolamine and / or calcium salts and of ester sulfate salts of polysaccharides.

[0143] Agar is formed from polymeric groups whose basic structure is β(1,3) D-galactopyranose and α(1,4) L3-6 anhydrogalactose chains, and these units repeat in a regular and alternating pattern. The difference among algal groups is the presence or absence of solvated methyl or carboxyethyl groups. These hybrid structures are generally present in varying percentages depending on the algae species and harvest time.

[0144] Agar is a mixture of polysaccharides (agarose and agaropectin) with a high molecular weight between 40,000 g mol and 300,000 g mol. It is obtained by producing concentrated solutions of algae extracts, generally by autoclaving and processing these concentrated solutions to subsequently extract about 2% agar.

[0145] In a preferred embodiment, (c) the anionic polysaccharide is selected from polysaccharides containing at least one glucuronic acid as a constituent, such as xanthan gum, gellan gum, gum arabic, alginic acid or alginates, and hyaluronic acid, in particular xanthan gum.

[0146] Examples of suitable synthetic anionic polysaccharides include anionic cellulose derivatives. The anionic cellulose derivatives include those containing carboxyalkyl groups, particularly C 1~4 Carboxyalkyl groups, such as carboxymethyl, carboxyethyl, carboxypropyl, and sulfoalkyl groups, particularly C 1~4 Mention may be made of those modified with sulfoalkyl groups, such as sulfomethyl groups. As anionic cellulose derivatives, mention may be made of carboxymethyl cellulose, carboxyethyl cellulose, carboxy-propyl cellulose, sulfoethyl carboxymethyl cellulose, carboxymethyl hydroxyethyl cellulose ("CM-HEC") and carboxymethyl cellulose.

[0147] The amount of the (c) anionic polysaccharide in the composition according to the present invention may be 0.01% by mass or more, preferably 0.05% by mass or more, and more preferably 0.1% by mass or more, based on the total mass of the composition.

[0148] The amount of (c) anionic polysaccharide in the composition according to the present invention may be 5% by mass or less, preferably 2% by mass or less, more preferably 1% by mass or less, based on the total mass of the composition.

[0149] The amount of the anionic polysaccharide (c) in the composition according to the present invention may be 0.01% by mass to 5% by mass, preferably 0.05% by mass to 2% by mass, and more preferably 0.1% by mass to 1% by mass, relative to the total mass of the composition.

[0150] (Nonionic polysaccharides) The composition according to the invention comprises (d) at least one nonionic polysaccharide. Two or more types of nonionic polysaccharides may be used in combination. Thus, a single type of nonionic polysaccharide or a combination of different types of nonionic polysaccharides may be used.

[0151] (d) The nonionic polysaccharide may be water-soluble.

[0152] (d) Nonionic polysaccharides may be selected, for example, from those described in "Encyclopedia of Chemical Technology", Kirk-Othmer, 3rd Edition, 1982, Vol. 3, pp. 896-900 and Vol. 15, pp. 439-458, in "Polymers in Nature" by EA MacGregor and CT Greenwood, published by John Wiley & Sons, Chapter 6, pp. 240-328, 1980, and in "Industrial Gums-Polysaccharides and their Derivatives", edited by Roy L. Whistler, 2nd Edition, published by Academic Press Inc., the contents of which three publications are incorporated by reference in their entirety.

[0153] Specifically, (d) nonionic polysaccharides include, for example, glucans, modified and unmodified starches (e.g., those derived from cereals, such as wheat, corn or rice, those derived from vegetables, such as peas, and those derived from tubers, such as potato or cassava), amylose, amylopectin, glycogen, dextran, cellulose and its derivatives (methylcellulose, hydroxyalkylcellulose, ethylhydroxyethylcellulose and carboxymethylcellulose). ), mannan, xylan, lignin, araban, galactan, galacturonan, chitin, glucuronoxylan, arabinoxylan, xyloglucan, glucomannan, arabinogalactan, tragacanth gum, ghatti gum, karaya gum, locust bean gum or carob gum, galactomannans such as guar gum and its non-ionic derivatives (e.g. hydroxypropyl guar), and mixtures thereof, which are different from the (b) cationic polysaccharides and (c) anionic polysaccharides described above.

[0154] Among the starches that may be used, mention may be made of macromolecules in the form of polymers containing elementary moieties, for example anhydroglucose units. The number of these moieties and their assembly make it possible to distinguish between amylose (a linear polymer) and amylopectin (a branched polymer). The relative proportions of amylose and amylopectin, and also their degree of polymerization, may vary as a function of the botanical origin of the starch.

[0155] The plant origin of the starch molecules used may be cereal or tuber, so the starch may be chosen, for example, from maize starch, rice starch, cassava starch, tapioca starch, barley starch, potato starch, wheat starch, sorghum starch and pea starch.

[0156] Starch is generally in the form of a white powder that is insoluble in cold water and which has a primary particle size in the range of 3 to 100 microns.

[0157] Starch is optionally C1 ~C 6 Hydroxyalkylation or C 1 ~C 6 It may be acylated (e.g. acetylated). The starch may also be subjected to a heat treatment.

[0158] The guar gum may be modified or unmodified.

[0159] Modified nonionic guar gum is, for example, C 1 ~C 6 It is modified with a hydroxyalkyl group.

[0160] Among the hydroxyalkyl groups that may be mentioned, for example, are the hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.

[0161] These guar gums are well known in the prior art and can be prepared, for example, by reacting guar gum with the corresponding alkene oxide, such as propylene oxide, to obtain guar gum modified with hydroxypropyl groups.

[0162] The degree of hydroxyalkylation corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxy functional groups present in the guar gum and may range, for example, from 0.4 to 1.2.

[0163] Such non-ionic guar gums, optionally modified with hydroxyalkyl groups, are sold, for example, by the company Solvay under the trade names Jaguar HP-8 COS, Jaguar HP-60 and Jaguar HP-120.

[0164] Among the celluloses used are, for example, hydroxyethyl cellulose and hydroxypropyl cellulose. Mention may be made of the products sold under the names Klucel EF, Klucel H, Klucel MF and Klucel G by the company Ashland.

[0194] The present invention will now be described in more detail by way of examples. However, these examples should not be construed as limiting the scope of the present invention.

[0195] In the examples, maltitol (and) sorbitol was obtained from Kankosha Co., Ltd., which is sold under the name "Amalty Syrup", and oryzanol was obtained from Tsuno Foods Co., Ltd., which is sold under the name "Gamma Oryzanol".

[0196] [Composition] Compositions according to Examples 1 to 3 (Ex. 1 to 3) and Comparative Examples 1 to 9 were prepared according to the following protocol. The blending ratios are shown in Tables 1 and 2 below. In Tables 1 and 2, all ingredients are based on "mass %" of the active ingredient.

[0197] [Preparation protocol] 1) Water, chlorphenesin, hydroxyacetophenone, and trisodium ethylenediamine disuccinate are mixed at 75-80° C. to form a homogeneous mixture. 2) Add pentylene glycol, Ceratonia siliqua gum, and xanthan gum, if present, to the mixture and mix at 75-80°C with a homogenizer until uniform. 3) Add ascorbic acid to the mixture and mix it with a homogenizer at 50° C. until it is homogenous. 4) Add sodium hydroxide to the mixture and mix it with a homogenizer at 50°C until it is homogenous. 5) Add hydroxypropyl guar hydroxypropyltrimonium chloride, if present, to the mixture and mix it with a homogenizer at 50°C until uniform. 6) The mixture is cooled to 30° C. without mixing.

[0198] [evaluation] (viscosity) The viscosity of each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 9 was measured at room temperature (25° C.) at 12 rpm using a viscometer (Brookfield LVDV-III U equipped with spindle #64). The viscosity was recorded 1 minute after the start of the measurement.

[0199] The preferred viscosity value is within the range of 4,000 to 9,000 mPa·s. When the viscosity value is less than 4,000 mPa·s, the composition may drip during application. When the viscosity value is more than 9,000 mPa·s, the composition may be too hard to spread on the skin.

[0200] (Hardness) The hardness of each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 9 was measured at room temperature (25° C.) at a speed of 2 mm / s using a texture analyzer equipped with a circular probe having a diameter of 5 mm, sold under the name TA-TX2i® by the company Rheo.

[0201] The preferred hardness value is in the range of 5-15g. When the hardness value is less than 5g, the composition may drip during application. When the hardness value is more than 15g, the composition may become like a jelly, which may be too hard to spread the composition evenly on the skin.

[0202] (Color change) 200 g of each of the compositions according to Examples 1 to 3 and Comparative Examples 1 to 9 was placed in a 250 mL plastic bottle, which was then left to stand for 2 months at 45° C. The color change in appearance was visually observed and then evaluated according to the following criteria. OK: the color was slightly browned but this was acceptable. NG: The color became noticeably brown and was not acceptable.

[0203] The results are summarized in Tables 1 and 2.
