Description

[Technical Field]

[0001] The present invention relates to a composition that contains a large amount of water but is stable and can provide a comfortable texture, preferably a cosmetic composition, and more preferably a skin cosmetic composition. [Background technology]

[0002] Providing a pleasant texture to the skin is one of the main characteristics of cosmetics, especially skincare cosmetics.

[0003] In particular, the refreshing sensation during application (e.g., caused by texture transformation, which corresponds to a change in the physical properties of the composition, such as the breakdown of the composition's structure, allowing the liquid to flow out of the composition), such as a water-repellent sensation, and the non-sticky feeling after application remain essential for customer satisfaction during use.

[0004] It should be noted that compositions that are unstable and easily undergo structural collapse often provide a pleasant texture. This means that it is difficult to provide both a pleasant feel and good stability at the same time.

[0005] Several techniques relating to O / W type compositions that provide improved texture and stability have been reported to date. For example, WO2024 / 106520 discloses a stable composition that can provide texture transformation.

[0006] However, sufficient research has yet been conducted on W / O type compositions that are stable, provide a cooling sensation during application, and leave little to no sticky feeling after application.

[0007] In addition, the formulations of environmentally friendly cosmetics are designed and developed with environmental issues in mind, and this is an important goal in efforts to address global problems.

[0008] Therefore, in order to address these environmental issues, it is essential to propose more sustainable compositions, preparation methods, and ingredients.

[0009] In this context, it is particularly important to develop new cosmetic compositions with a better carbon footprint by promoting the use of renewable raw materials, and / or materials with a good index of naturalness, and / or materials of natural origin.

[0010] In order to provide a cooling sensation during application, such as the feeling of water splashing, increasing the amount of water in a W / O type composition has already been proposed.

[0011] However, when there is a large amount of water in a W / O type composition, the proportion of aqueous droplets tends to be high, the droplets tend to be large, and they tend to be close to each other. Therefore, in the case of these compositions, the risk of droplet coalescence increases, leading to destabilization of the composition.

[0030] As a result of diligent research, the inventors have discovered that it is possible to provide a stable composition that, despite containing a large amount of water, can not only provide a refreshing sensation but also reduce or eliminate any sticky feeling.

[0031] Therefore, one aspect of the present invention is: (a1) At least one first polyglyceryl fatty acid ester having an HLB value of 4 or less, (a2) At least one second polyglyceryl fatty acid ester having an HLB value greater than 4, (b) at least one lipophilic thickener, (c) At least one hydrophilic thickener selected from nonionic polysaccharides, (d) at least one type of oil, and (e) water A composition comprising, (e) The amount of water is more than 50% by mass, preferably more than 55% by mass, and more preferably more than 60% by mass, based on the total mass of the composition. The composition is either silicone-free or contains less than 1% by mass, preferably less than 0.5% by mass, and more preferably less than 0.1% by mass, of the total mass of the composition.

[0032] The composition according to the present invention is stable despite containing a large amount of water and can provide a refreshing sensation, such as a water-like feeling, as well as reducing or eliminating the sticky feeling that is provided.

[0033] The composition according to the present invention remains stable immediately after preparation and even under temperature changes from cold to high temperatures, and for extended periods after preparation. Therefore, the composition according to the present invention is stable over time and can be stored for long periods, even under temperature changes that occur in summer.

[0034] The composition according to the present invention can provide a refreshing sensation, such as a water-like feeling, preferably during application.

[0035] The composition according to the present invention can provide a texture transformation during application, preferably in the initial stages of application. Texture transformation here refers to a change in the physical properties of the composition, such as a breakdown of its structure, e.g., a change in texture from a gel or cream to a liquid, which allows the liquid to flow out of the composition. This texture transformation can provide a cooling sensation.

[0036] The compositions according to the present invention can also preferably reduce or eliminate the sticky feeling after application.

[0037] In this context, the term "sticky" refers to the property of providing an oily sensation to the skin.

[0038] The composition according to the present invention contains (d) oil and can provide an oily or sticky feeling after application.

[0039] However, the compositions according to the present invention, despite containing (d) oil, can eliminate or reduce the oily or sticky feeling provided.

[0040] Therefore, the composition according to the present invention can provide a comfortable texture, in particular, an excellent feel, during or after application of the composition.

[0041] In addition, the compositions according to the present invention contain silicone in a very limited amount or not at all.

[0042] Furthermore, the composition according to the present invention may contain, in a very limited amount, or may not contain at all, a surfactant comprising at least one polyoxyalkylene moiety, for example, a polyoxyethylene moiety, such as a polyethylene glycol (PEG)-based surfactant.

[0043] Furthermore, (a1) the first polyglyceryl fatty acid ester and / or (a2) the second polyglyceryl fatty acid ester may be biodegradable.

[0044] Therefore, the composition according to the present invention is environmentally friendly.

The HLB value can be calculated using the formula HLB = 20 * (1 - S / A) [wherein S is the saponification value of the ester and A is the neutralization value of the fatty acid].

[0053] If two or more (a1) first polyglyceryl fatty acid esters are used, the HLB value is determined by the weighted average of the HLB values ​​of all (a1) first polyglyceryl fatty acid esters.

Thus, (a1) the first polyglyceryl fatty acid ester may be polyglycerol polyricinoleate (PGPR), i.e., a polyglyceryl ester of polyricinoleate, preferably a polyglyceryl monoester.

The HLB value can be calculated using the formula HLB = 20 * (1 - S / A) [wherein S is the saponification value of the ester and A is the neutralization value of the fatty acid].

[0077] If two or more (a2) second polyglyceryl fatty acid esters are used, the HLB value is determined by the weighted average of the HLB values ​​of all (a2) second polyglyceryl fatty acid esters.

[0078] (a2) The second polyglyceryl fatty acid ester may be a non-polymerized polyglyceryl fatty acid ester or a polymerized polyglyceryl fatty acid ester.

[0111] As the fatty acid dextrin ester, one can be selected from dextrin monoesters and polyesters of at least one fatty acid, for example, formula (II):

[0112] [ka]

[0113] [In the formula, n is an integer within the range of 3 to 200, for example, within the range of 20 to 150, for example, within the range of 25 to 50. The R1, R2, and R3 groups may be the same or different, and are selected from hydrogen and acyl groups (R-CO-), where the acyl group R is selected from linear, branched saturated and unsaturated hydrocarbon groups containing 6 to 50 carbon atoms, for example 7 to 29, in a further example 7 to 21, for example 11 to 19, in yet another example 13 to 17, or even 15 carbon atoms, provided that at least one of the R1, R2, or R3 groups is not hydrogen. We can list the corresponding items.

[0114] For example, R1, R2, and R3 can be selected from hydrogen and an acyl group (R-CO-) [wherein the formula, the acyl group R is a hydrocarbon group as defined above, provided that at least two of the R1, R2, or R3 groups are identical and not hydrogen].

[0115] The R1, R2, and R3 groups may all be the same or contain different acyl groups (R-CO-). In one embodiment, the acyl groups are the same.

[0116] For example, in the ester of formula (II) disclosed herein, n may be in the range of 25 to 50, and may be equal to, for example, 38.

[0117] When the R1, R2, and R3 groups, which may be the same or different, contain an acyl group (R-CO-), examples of acyl groups selected from caprylyl, caproyl, lauroyl, myristyl, palmityl, stearyl, eicosanyl, docosanoyl, isovaleryl, ethyl-2 butyryl, ethylmethylacetyl, isoheptanyl, ethyl-2 hexanyl, isononanyl, isodecanyl, isotridecanyl, isomiristyl, isopalmityl, isostearyl, isohexanyl, decenyl, dodecenyl, tetradecenyl, myristyl, hexadecenoyl, palmitrail, oleyl, elaidyl, eicosenyl, sorbyl, linoleyl, linolenyl, punicyl, arachidonyl, stearolyl group, and mixtures thereof can be listed.

[0118] At least one type of palmitate dextrin can be used as a fatty acid dextrin ester. This ester may be used alone or in a mixture with other esters.

[0119] The dextrin ester of fatty acid may have a degree of substitution of 2.5 or less relative to one glucose unit, for example, in the range of 1.5 to 2.5, for example, 2 to 2.5 relative to one glucose unit. The mass-average molecular weight of the dextrin ester may be 10,000 to 150,000, for example, 12,000 to 100,000, for example, 15,000 to 80,000.

[0120] Fatty acid dextrin esters, such as palmitate dextrin, are commercially available from Chiba Flour under the names Rheopearl TL or Rheopearl KL.

[0121] (b) The lipophilic thickener may not be a wax. Therefore, in preferred embodiments of the present invention, (b) the lipophilic thickener is not selected from waxes.

[0122] (b) The lipophilic thickener is preferably selected from non-wax lipophilic thickeners, more preferably from non-wax lipophilic organic thickeners, and even more preferably from fatty acid dextrin esters, such as dextrin palmitate.

[0123] The amount of (b) lipophilic thickener 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.

[0124] The amount of (b) lipophilic thickener in the composition according to the present invention may be 15% by mass or less, preferably 10% by mass or less, and more preferably 5% by mass, based on the total mass of the composition.

[0125] The amount of (b) lipophilic thickener in the composition according to the present invention may be 0.01% to 15% by mass, preferably 0.05% to 10% by mass, and more preferably 0.1% to 5% by mass, based on the total mass of the composition.

[0126] (Hydrophilic thickener) The composition according to the present invention may further contain (c) at least one hydrophilic thickener selected from nonionic polysaccharides. If two or more such hydrophilic thickeners are used, they may be the same or different.

[0127] (c) A hydrophilic thickener can thicken the composition according to the present invention by thickening the aqueous phase of the composition according to the present invention.

[0128] According to the present invention, the "hydrophilic thickener" increases the viscosity of the first composition into which it is introduced at room temperature (25°C), atmospheric pressure, and 1 sq. -1At this shear rate, the viscosity can be increased by at least 20 cps, preferably at least 50 cps (viscosity can be measured using a cone / plate viscometer, Haake R600 rheometer, etc.).

[0129] Nonionic polysaccharides can be selected from non-cellulosic polysaccharides.

[0130] Non-cellulose polysaccharides, in this context, refer to polysaccharides that are not derived from cellulose. Therefore, cellulose and its derivatives, such as polyquaternium-10, are not included in the category of non-cellulose polysaccharides.

[0131] Nonionic polysaccharides may have a linear or branched structure, preferably a linear structure.

[0132] Nonionic polysaccharides may be homopolysaccharides containing a single type of monosaccharide, or heteropolysaccharides containing two or more different types of monosaccharides.

[0133] Nonionic polysaccharides are preferably biodegradable. The term "biodegradable" means that nonionic polysaccharides can be broken down or altered in the environment or in living organisms, for example, due to metabolism by microorganisms that may be present in the environment or in living organisms. Biodegradable nonionic polysaccharides can also be broken down by hydrolysis.

[0134] (c) The hydrophilic thickener is selected from nonionic polysaccharides and is preferably derived from natural resources, such as plants and microorganisms.

[0135] Examples of plant-derived nonionic polysaccharides include modified and unmodified starches (e.g., those derived from grains such as wheat, maize, or rice; vegetables such as those derived from yellow peas; and tubers such as those derived from potatoes or cassava), amylose, amylopectin, glycogen, mannan, glucomannan, xylan, araban, galactan, xyloglucan, arabinogalactan, agar, locust bean gum or carob gum, tamarind seed gum, dextrin, galactomannan, such as tara gum and guar gum, and their nonionic derivatives (e.g., hydroxypropyl guar), as well as mixtures thereof.

[0136] Among the starches that can be used, for example, polymers containing elemental parts that are anhydrous glucose units can be cited. The number of these parts, and their arrangement, can distinguish between amylose (linear polymers) and amylopectin (branched polymers). The relative proportions of amylose and amylopectin, and their degrees of polymerization, can vary depending on the plant origin of the starch.

[0137] The plant origin of the starch molecules used can be grains or tubers. Therefore, the starch can be selected from, for example, corn starch, rice starch, cassava starch, tapioca starch, barley starch, potato starch, wheat starch, sorghum starch, and pea starch.

[0138] Starch is generally in the form of a white powder that is insoluble in cold water and has a basic particle size in the range of 3 to 100 microns.

[0139] The starch may optionally be C1-C6 hydroxyalkylated or C1-C6 acylated (e.g., acetylated). The starch may also be heat-treated.

[0140] Guar gum may be denatured or undenatured.

[0141] Modified nonionic guar gum is modified, for example, with C1-C6 hydroxyalkyl groups.

[0142] Examples of hydroxyalkyl groups include hydroxymethyl, hydroxyethyl, hydroxypropyl, and hydroxybutyl groups.

[0143] These guar gums are well known in the prior art, and the corresponding alkene oxides can be prepared by reacting them with guar gum, for example, propylene oxide to obtain guar gum modified with a hydroxypropyl group.

[0144] The degree of hydroxyalkylation corresponds to the number of alkylene oxide molecules consumed divided by the number of free hydroxyl functional groups present in the guar gum, and can be in the range of, for example, 0.4 to 1.2.

[0145] Such nonionic guar gums, optionally modified with hydroxyalkyl groups, are marketed, for example, by Solvay under the trade names Jaguar HP-8 COS, Jaguar HP-60, and Jaguar HP-120.

[0146] (c) The hydrophilic thickener selected from nonionic polysaccharides is more preferably selected from those derived from microorganisms, sometimes called nonionic "biopolysaccharides."

[0147] Microbial polysaccharides, or biopolysaccharides, refer to polysaccharides produced by microorganisms, such as bacteria (germs or bacteria). Microbial polysaccharides can be produced through the fermentation of sugars by microorganisms.

[0148] Polysaccharides derived from microorganisms may contain units selected from mannose, glucose, galactose, rhamnose, and mixtures thereof.

[0149] Polysaccharides derived from microorganisms may, at their discretion, be chemically modified.

[0150] Examples of nonionic biopolysaccharides include cardran, gellan gum, dextran, pullulan, sclerotium gum, and mixtures thereof.

[0151] (c) The hydrophilic thickener is preferably selected from the group consisting of nonionic polysaccharides derived from microorganisms, more preferably curdlan, gellan gum, dextran, pullulan, sclerotium gum, and mixtures thereof.

[0180] The term "aliphatic" in the context of aliphatic alcohols means that they contain a relatively large number of carbon atoms. Therefore, alcohols having four or more, preferably six or more, and more preferably twelve or more carbon atoms are included in the range of aliphatic alcohols. Aliphatic alcohols may be saturated or unsaturated. Aliphatic alcohols may be linear or branched.

[0203] The term "filler" should be understood to mean colorless or white inorganic or synthetic particles that are insoluble in the liquid components that may be present in the composition according to the present invention, regardless of the temperature at which the composition is manufactured.

[0204] The filler may be inorganic or organic, and may be spherical or oval, or in any crystalline form (e.g., plate-like, cubic, hexagonal, orthorhombic, etc.). Non-limitingly, talc, mica, silica, silica silylate, kaolin, sericite, calcined talc, calcined mica, calcined sericite, synthetic mica, bismuth oxychloride, barium sulfate, boron nitride, calcium carbonate, magnesium carbonate, magnesium bicarbonate, and powders formed from polyamide (Nylon®), poly-β-alanine, and polyethylene, powders formed from polyurethane, powders formed from tetrafluoroethylene polymer (Teflon®), lauryl lysine, starch, polymer hollow microspheres, e.g., poly(vinylidene chloride) / acrylonitrile hollow microspheres, e.g., ExpanseL® (Nobel Examples include hollow microspheres of acrylic acid copolymers (Industrie Inc.), silicone resin microbeads (e.g., Tospearls® from Toshiba Inc.), particles formed from polyorganosiloxane elastomers, precipitated calcium carbonate, magnesium carbonate, basic magnesium carbonate, porous silica, hollow silica microspheres, glass or ceramic microcapsules, or metal soaps derived from organic carboxylic acids having 8 to 22 carbon atoms, for example, 12 to 18 carbon atoms, such as zinc stearate, magnesium stearate, lithium stearate, zinc laurate, or magnesium myristate.

[0205] In the present invention, examples of fillers include modified or unmodified starch.

[0206] Modified starch is based on base starch. Base starch, as used herein, is intended to include all starches derived from any natural source, any of which may be suitable for use herein. Natural starch, as used herein, is one found in nature. Starches derived from plants obtained by standard breeding techniques, including hybrid breeding, translocation, inversion, and transformation, or by any other method of genetic or chromosome engineering to include such varieties, are also suitable. In addition, starches derived from plants grown from artificial mutants and varieties of the above-mentioned common starches, which can be produced by the known standard method of mutation breeding, are also suitable.

[0207] Typical sources of starch are grains, tubers, roots, legumes, and fruits. Natural sources may include waxy maize, peas, potatoes, sweet potatoes, bananas, barley, wheat, rice, oats, sago, amaranth, tapioca (cassava), arrowroot, canna, and sorghum, as well as low-amylose and high-amylose varieties thereof. As used herein, the term "low-amylose" starch is intended to include starches containing about 10% by mass or less, particularly 5% by mass or less, and more specifically 2% by mass or less of amylose. As used herein, the term "high-amylose" starch is intended to include starches containing at least about 50% by mass, particularly at least about 70% by mass, and more specifically at least about 80% by mass of amylose. High-amylose starch may be preferred.

[0208] As an example of unmodified starch, we can mention Zea mays (corn) starch, which is commercially available from Roquette Freres as Beaute by Roquette® ST005.

[0209] Modified starch may be pregelatinized. Pregelatinization and techniques for achieving pregelatinization are known in the art and are disclosed, for example, in U.S. Patents 4,465,702, 5,037,929, 5,131,953 and 5,149,799. See also Chapter XXII, “Production and Use of Pregelatinized Starch,” Starch: Chemistry and Technology, Vol. III – Industrial Aspects, RL Whistler and EF Paschall, Editors, Academic Press, New York, 1967. The term “pregelatinized” is intended to mean swollen starch particles that have lost their birefringence and / or Maltese cross in polarized light. Such pregelatinized starch derivatives are substantially soluble in cold water without heating. In this context, “soluble” does not necessarily mean the formation of a true molecular solution, but may also mean a colloidal dispersion. In one embodiment, the starch is completely pre-gelatinized.

[0210] Pre-gelatinized and modified starch can be easily and quickly dissolved even in cold water.

[0211] Pre-gelatinization can be achieved by methods including, but not limited to, drum drying, extrusion, and spray drying. In one embodiment, extrusion is used to simultaneously heat-cook and dry the starch (see, for example, U.S. Patent No. 3,137,592). This method utilizes the physical treatment of the starch / water mixture under high temperature and pressure, which results in the gelatinization of the starch, and the subsequent expansion after exiting the nozzle due to the rapid evaporation of the water.

[0212] In one embodiment, pre-gelatinization is completed to obtain good solubility and remove undissolved particles in the composition that may result in an unpleasant gritty texture.

[0213] In one embodiment, the starch is mostly in its original state as starch granules. An aqueous dispersion of a pre-gelatinized starch derivative having mostly its original granular structure typically has a more uniform and smoother texture than an aqueous dispersion of starch without a granular structure, which may have a slightly rougher feel. In the case of pre-gelatinized starch having its original granular structure, the natural internal structure of hydrogen bonds is broken, but the external shape or form is maintained.

[0214] Modified starch may be crosslinked. Crosslinking of starch chains can be achieved by suitable crosslinking agents, i.e., bifunctional compounds. In one embodiment, the crosslinking method used is a phosphorylation reaction in which starch is reacted with phosphorus oxychloride, phosphorus pentoxide and / or sodium trimetaphosphate. Two starch chains are crosslinked by an anionic PO group. The anionic features of the crosslinking site support the emulsifying stabilization effect of the starch used according to the present invention. In another embodiment, the crosslinking method is C4-C8 alkanedicarboxylic acids, including, but is not limited to, C4-C8 alkanedicarboxylic acids, as exemplified by adipic acid. 18 The crosslinking is based on alkanes or alkenedicarboxylic acids. The alkanes or alkenedicarboxylic acids link two starch chains via ester bonds. This can be in a linear or branched chain form. Derivatives can be obtained, for example, by reacting starch with a mixed anhydride of dicarboxylic acid and acetic acid. In one embodiment, less than 0.1 mass percent of the crosslinking agent is used based on dry starch. In another embodiment, about 0.06 to 0.1 mass percent of the crosslinking agent is used based on dry starch.

[0215] Modified starch is preferably hydrophobic. More preferably, the surface of the modified starch is hydrophobic.

[0216] The modification that makes starch hydrophobic involves the addition of hydrophobic functional groups, such as C. 1~6 Acyl(acetyl), C 1~6This can be carried out by grafting a hydroxyalkyl (hydroxyethyl or hydroxypropyl), carboxymethyl, or octenyl succinate group.

[0218] The modified starch is preferably hydroxyalkyl modified starch.

[0219] The hydroxyl groups are bonded to the starch backbone via alkyl groups, for example, 2 to 6 carbon atoms of the alkyl group, but their position is not important and can be from the alpha to the omega position. In a preferred embodiment, the degree of substitution of the hydroxyalkylation is approximately 0.08 to 0.3. The degree of substitution is the average number of substituted OH groups in a starch molecule per unit of anhydrous glucose. Hydroxyalkylation of starch can be carried out by reacting natural starch with an alkylene oxide having a suitable number of carbon atoms, and this includes, but is not limited to, hydroxypropylation by the reaction of starch with propylene oxide. Hydroxyalkyl-modified starch can also contain multiple hydroxyl groups per alkyl group.

[0221] The method for preparing hydroxyalkyl-modified starch can be carried out in any order. However, those skilled in the art will understand the advantages of a particular order. For example, since a typical hydroxypropylation method can destroy some of the crosslinks achieved, when crosslinking starch, hydroxypropylation is typically carried out before crosslinking with phosphorus oxychloride.

(2) Once the target powder is completely wet and begins to form a paste, the mass of the added water is determined as the mass of the wetting point. (3) The wetting point in water is calculated using the following formula: Wetting point in water (ml / 100g) = {(mass at the wetting point) / 2g} × 100 / density of water.

[0311] Temperature change cycle: a) Maintain the composition at 4°C for 6 hours. b) Raise the temperature of the composition to 25°C over a period of 6 hours. c) Raise the temperature of the composition to 37°C over a period of 6 hours. d) Raise the temperature of the composition to 45°C over a period of 6 hours. e) Reduce the temperature of the composition to 4°C.

[0312] Ten cycles were performed, and the defects of the compositions between cycles were evaluated. Specifically, each composition was examined in terms of the degree of change in appearance (e.g., syneresis, separation, and creaming), color (e.g., yellowing and browning), and odor (e.g., malodor), and evaluated according to the following criteria. Excellent condition: Almost the same as when it was manufactured. Good: Little to no change was observed in appearance, color, or smell. Defective: Clear changes in appearance, color, and odor were observed. Extremely poor: Significant changes in appearance, color, and odor were observed.

[0313] The results are shown in Table 1.

[0314] (summary) As is evident from Table 1, the compositions according to the present invention (Examples 1-3) can provide excellent cosmetic effects in terms of texture transformation during application, non-sticky feel after application, and stability under temperature changes over two months, which may be due to the presence of components (d) and (e) and the combination of components (a1), (a2), (b), and (c). Examples 2-3 show that the non-sticky feel after application can be further improved by the addition of component (f). Therefore, the compositions according to the present invention can provide, in particular, an excellent feel and long-term stability even under temperature changes.

[0315] On the other hand, the composition according to Comparative Example 1, which did not contain component (a2) (the second polyglyceryl fatty acid ester), showed inferior stability.

[0316] The composition according to Comparative Example 2, which did not contain component (a1) (the first polyglyceryl fatty acid ester), also showed inferior stability.

[0317] The composition according to Comparative Example 3, which did not contain component (b) (lipophilic thickener), also showed poor stability.

[0318] The compositions of Comparative Examples 4 and 5, which did not contain component (c) (a hydrophilic thickener selected from nonionic polysaccharides), also showed poor stability. It should be noted that xanthan gum has a carboxyl group and is therefore an anionic polysaccharide.

[0319] The composition according to Comparative Example 6, which contained a small amount of water, failed to provide excellent cosmetic effects in terms of texture transformation during application, non-sticky feeling after application, and stability under temperature changes over a period of two months.
