Description

Technical Field

[0006] , , , ,

[0001] The present invention relates to a spray composition, and more specifically, to a spray composition containing galactomannan.

Background Art

[0002] Conventionally, galactomannan has been used in the fields such as cosmetics.

[0003] For example, Non-Patent Document 1 and Non-Patent Document 2 describe a moisturizer containing water, galactomannan, and glycerin. When this moisturizer is applied to the skin, it thickens and gels with the evaporation of some water, forming a film on the skin. As a result, the evaporation rate of the remaining water is slowed down, and it is said that the moisturizing effect can be sustained.

[0004] By the way, if a moisturizer can be sprayed, the complexity of application can also be reduced. Therefore, a sprayable moisturizer has a high commercial value. For example, Patent Document 1 proposes a sprayable cosmetic containing deacylated gellan gum.

Summary of the Invention

[0007] However, the inventors' investigation revealed that the composition containing galactoxyloglucan described in Non-Patent Literature 1 is difficult to spray. More specifically, a composition prepared by dissolving 1.0% by mass of galactoxyloglucan described in Non-Patent Literature 1 together with 7.0% by mass of glycerin in water, while possessing moisturizing properties, was difficult to spray. In contrast, spraying was possible when the concentration of galactoxyloglucan was below a predetermined value, but in this case, it was found that the moisturizing properties were not sufficiently exhibited.

[0008] Furthermore, while the cosmetic composition described in Patent Document 1 excels in providing a refreshing and invigorating feel, its moisturizing effect has not been evaluated.

[0009] In view of the above circumstances, the object of the present invention is to provide a sprayable composition that is sprayable and has excellent moisturizing properties. [Means for solving the problem]

[0010] The inventors have found that using galactoxyloglucan with a viscosity below a predetermined value, i.e., low-viscosity galactoxyloglucan, improves the sprayability of the spray composition. In addition, the inventors have also found that even when using low-viscosity galactoxyloglucan, sufficient moisturizing properties can be imparted to the spray composition compared to the galactoxyloglucan described in Non-Patent Document 1.

[0011] Based on the above findings, the spray composition according to the present invention comprises water, a low-viscosity galactoxyloglucan exhibiting a viscosity of 150 mPa·s or less in a 1.5% by mass aqueous solution, and a polyol. The content of the low-viscosity galactoxyloglucan relative to the total mass of the spray composition is 0.3 to 2.3% by mass.

[0012] With this configuration, the galactoxyloglucan is a low-viscosity galactoxyloglucan, and the content of the low-viscosity galactoxyloglucan is within the above range, resulting in a product that is not only sprayable but also has excellent moisturizing properties.

[0013] Furthermore, the spray composition according to the present invention preferably has a viscosity of 100 mPa·s or less in a 1.5% by mass aqueous solution of the low-viscosity galactoxyloglucan, and more preferably a viscosity of 50 mPa·s or less.

[0014] With this configuration, the low-viscosity galactoxyloglucan exhibits the viscosity described above, making it easier to spray.

[0015] Furthermore, the spray composition according to the present invention preferably contains 0.5 to 2.0% by mass of the low-viscosity galactoxyloglucan relative to the total mass of the spray composition.

[0016] With this configuration, the low-viscosity galactoxyloglucan content is within the above range, making it easier to spray and providing superior moisturizing properties. [Effects of the Invention]

[0017] As described above, the present invention provides a sprayable composition that is sprayable and has excellent moisturizing properties. [Modes for carrying out the invention]

[0018] The following describes a spray composition according to one embodiment.

[0019] The spray composition according to this embodiment comprises water, a low-viscosity galactoxyloglucan, and a polyol. The spray composition of this embodiment is used as a moisturizer for human skin, hair, and oral cavity.

[0020] Galactoxyloglucan is a natural polysaccharide present in the cell walls (primary walls) of higher plants such as dicotyledons and monocotyledons. Galactoxyloglucan is composed of glucose, xylose, and galactose as constituent sugars. The main chain of galactoxyloglucan is composed of glucose linked by β-1,4 bonds, and the side chains are composed of xylose bonded to the glucose of the main chain and galactose bonded to the xylose. Galactoxyloglucan is obtained from tamarind, seeds of the genus Himeanea, soybeans, mung beans, kidney beans, rice, barley, apples, etc. Among these, those derived from tamarind seeds, which are easily available, are preferred. Also, as commercially available galactoxyloglucan, Griloid (registered trademark) manufactured by DSP Gokyo Foods & Chemical Co., Ltd. can be mentioned.

[0021] In the present invention, it is important to use low-viscosity galactoxyloglucan among galactoxyloglucans. The low-viscosity galactoxyloglucan means that the viscosity of a 1.5 mass% aqueous solution of low-viscosity galactoxyloglucan (mass of low-viscosity galactoxyloglucan: mass of water = 1.5:98.5) shows 150 mPa·s or less. The viscosity is measured using a B-type viscometer under the conditions of a measurement temperature of 25°C and a rotation speed of 30 rpm.

[0022] From the viewpoint of sprayability, the viscosity is preferably 95 mPa·s or less, more preferably 75 mPa·s or less, and even more preferably 70 mPa·s or less. Also, when the viscosity is such a value, stickiness to the skin, hair, etc. and stickiness in the oral cavity by the spray composition can be suppressed. From the viewpoints of film-forming property and moisturizing property to the skin, etc., the viscosity is preferably 10 mPa·s or more.

[0023] Low-viscosity galactoxyloglucan is prepared by decomposing galactoxyloglucan such as Griloid (registered trademark). Also, by adjusting the degree of this decomposition, the viscosity can be appropriately changed.

[0024] For example, low-viscosity galactoxyloglucan can be prepared by chemical, physical, or enzymatic degradation of galactoxyloglucan.

[0025] Chemical decomposition methods include acid hydrolysis and alkali hydrolysis. Acids used in acid hydrolysis include inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid, or nitric acid, and organic acids such as citric acid, succinic acid, tartaric acid, acetic acid, or propionic acid. Among these, sulfuric acid and citric acid are preferred. Bases used in alkali hydrolysis include inorganic bases such as sodium hydroxide, potassium hydroxide, or calcium hydroxide.

[0026] Physical decomposition methods include heat treatment, high-pressure homogenization, ultrasonic treatment, or mechanical shearing.

[0027] Enzymes used for enzymatic degradation include β-1,4-glucanase, that is, plant tissue-degrading enzymes with so-called cellulase activity.

[0028] Low-viscosity galactoxyloglucan is preferably prepared by acid hydrolysis. More specifically, low-viscosity galactoxyloglucan can be prepared as follows. First, galactoxyloglucan is dispersed in an aqueous alcohol solution, then an acid is added and the mixture is heated. After that, an alkali is added to neutralize the mixture, and the precipitate is collected. The precipitate is then washed with an aqueous alcohol solution and dried to obtain low-viscosity galactoxyloglucan. The amount of galactoxyloglucan used in the preparation of low-viscosity galactoxyloglucan is 0.1 to 20% by mass relative to the total volume of the aqueous alcohol solution. Lower alcohols such as methanol, ethanol, and isopropanol are preferred. The concentration of the aqueous alcohol solution is preferably 30 to 80% by mass. The amount of acid added is 0.1 to 20% by weight relative to the aqueous alcohol solution, preferably 1 to 10% by weight. The pH of the solution is preferably less than 4. The reaction temperature is 20°C to 150°C, preferably 40°C to 121°C. The reaction time can be adjusted by measuring and monitoring the desired reaction time with, for example, a B-type viscometer [manufactured by Toki Sangyo Co., Ltd.], and is usually from a few seconds to 48 hours, with 1 to 24 hours being preferred. The amount of alkali added is such that the solution becomes neutral (approximate pH: 6 to 8).

[0029] The content of low-viscosity galactoxyloglucan is preferably 0.3 to 2.2% by mass, more preferably 0.8 to 2.2% by mass, and even more preferably 1.2 to 2.2% by mass, based on the total mass of the spray composition.

[0030] In particular, when the content of low-viscosity galactoxyloglucan is above a predetermined value, the amount of water adhering to the low-viscosity galactoxyloglucan also increases, which is preferable because it allows the moisturizing properties of the spray composition to be maintained for a long period of time. From this viewpoint, the content of low-viscosity galactoxyloglucan is preferably 0.5% by mass or more, and more preferably 1.0% by mass or more. Note that the spray composition containing galactoxyloglucan described in Non-Patent Document 1 cannot be sprayed if the galactoxyloglucan content is too high, and therefore the above-mentioned effects cannot be expected.

[0031] Polyols include sugars and alcohols having two or more hydroxyl groups.

[0032] The aforementioned sugars are preferably three-carbon sugars or more and ten-carbon sugars or less, for example, triose (three-carbon sugar, e.g., glyceryl aldehyde, dihydroxyacetone, etc.), tetrose (tetracarbon sugar, e.g., erythrose, threose, erythrolose, etc.), pentose (five-carbon sugar, e.g., ribose, lyxose, xylose, arabinose, abiose, ribulose, xylulose, etc.), hexose (six-carbon sugar, e.g., glucose, mannose, galactose, idose, Examples include aldose-type and ketose-type monosaccharides such as fructose (fructose, sovose, etc.) and heptose (sedoheptulose, coliose, etc.), disaccharides such as sucrose, maltose, trehalose, and cellobiose, trisaccharides such as maltotriose, oligosaccharides such as galactooligosaccharides, decomposition products of water-soluble polymers such as dextrin (excluding the low-viscosity galactoxyloglucan), and sugar alcohols such as xylitol, sorbitol, mannitol, and erythritol. Furthermore, the sugars may be one selected from these, or a mixture of two or more.

[0033] The aforementioned alcohols include alcohols and alcohol derivatives. Preferably, the alcohols have 3 to 10 carbon atoms, and examples include dihydric alcohols (e.g., propylene glycol, butylene glycol, pentanediol, etc.), trihydric alcohols (e.g., glycerin, trimethylolpropane, etc.), tetrahydric alcohols (e.g., diglycerin, pentaerythritol such as 1,2,6-hexanetriol, etc.), polyhydric alcohol polymers (e.g., dipropylene glycol, triethylene glycol, polyethylene glycol, polyglycerin, etc.), and derivatives of polyhydric alcohols. Furthermore, the aforementioned alcohols may be one selected from these, or a mixture of two or more.

[0034] As the polyhydric alcohol derivative, alkylene oxide addition polymers of dihydric to tetrahydric alcohols are preferred examples. Examples of alkylene oxides to be added polymerized include ethylene oxide (EO), propylene oxide (PO), and butylene oxide (BO). Specifically, for example, the alkylene oxide addition polymers of the aforementioned dihydric to tetrahydric alcohols include PPG-40 butyl [i.e., POP(40) butyl ether] (commercially available as "Unilube MB-370", etc.), PPG-30 buteth-30 [i.e., POE(30)·POP(30) butyl ether] (commercially available as "Unilube 50 MB-72", etc.), and PPG-16 glyceryl ether (commercially available as "Uniol TG-1000"). Examples include PPG-24 Glyceryl-24 (such as "Unilube 50TG-32" as a commercially available product), PPG-25-Polyethylene Glycol-25 Trimethylolpropane (such as "Unilube 43TT-2500" as a commercially available product), PPG-14 Diglyceryl (such as "Unilube DGP-950"), and PEG-5-PPG-65 Pentaerythrityl (such as "Unilube 5TP-300KB") (all manufactured by NOF Corporation). Here, PPG represents polypropylene glycol, POP represents polyoxypropylene, POE represents polyoxyethylene, and PEG represents polyethylene glycol.

[0035] Sugar alcohols, a type of polyhydric alcohol, function as both sugars and alcohols, with pentahedral and hexahedral alcohols such as sorbitol and mannitol being preferred examples. As derivatives of these sugar alcohols, alkylene oxide addition polymers of sugar alcohols are preferred examples. Examples of alkylene oxides used in addition polymerization include EO, PO, and BO. Specifically, examples include POP sorbitol (such as "Uniol HS-1600D" (manufactured by NOF Corporation), a commercially available product), POE(10) methyl glucoside (such as "Glucam E-10" (manufactured by Lubrizol Nippon Co., Ltd.), a commercially available product), and POP(20) methyl glucoside (such as "Glucam P-20" (manufactured by Lubrizol Nippon Co., Ltd.), a commercially available product).

[0036] Preferred polyols include glycerin, diglycerin, polyglycerin, 1,3-butylene glycol, propylene glycol, dipropylene glycol, pentylene glycol, isoprene glycol, sorbitol, glucose, mannitol, trehalose, xylitol, and polyethylene glycol. These may be used individually or in combination.

[0037] The molecular weight of the polyol is preferably 2,000 or less, more preferably 1,500 or less, and even more preferably 1,000 or less.

[0038] The polyol content is preferably 2.5 to 27.5% by mass relative to the total mass of the spray composition.

[0039] Deionized water or distilled water is preferred. The water content is usually 50% by mass or more, preferably 60% by mass or more, and more preferably 70% by mass or more, based on the total mass of the spray composition.

[0040] The viscosity of the spray composition is preferably 50 mPa·s or less, more preferably 30 mPa·s or less, even more preferably 15 mPa·s or less, and even more preferably 10 mPa·s or less. This facilitates the operation of filling the spray container with the spray composition. This is advantageous when the spray container is used repeatedly, i.e., in the case of a refillable spray container. In contrast, in the spray composition containing deacyl gellan gum described in Patent Document 1, it is difficult to reduce the viscosity due to the viscosity of the deacyl gellan gum compared to one containing low-viscosity galactoxyloglucan. That is, when using polysaccharides that exhibit relatively high viscosity, such as deacyl gellan gum, it is difficult to improve the ease of filling while maintaining the predetermined concentration that exhibits its performance. Furthermore, because the spray composition of this embodiment has the viscosity described above, it can also suppress stickiness on the skin and hair, as well as stickiness in the mouth. Furthermore, the spray composition of this embodiment exhibits excellent moisturizing properties even at relatively low viscosity values ​​as described above.

[0041] Examples of spray containers for filling with the spray composition of this embodiment include pump-type atomizers, trigger-type atomizers, and aerosol-type atomizers.

[0042] The spray composition of this embodiment can be used in cosmetics such as lotions, serums, antiperspirants, sunscreens, foundations, and hair styling products. In other words, the spray composition of this embodiment can be applied to the skin and hair. Furthermore, the spray composition of this embodiment can also be applied to the oral cavity and nasal cavity.

[0043] As described above, one embodiment has been presented as an example, but the spray composition according to the present invention is not limited to the configuration of the above embodiment. Furthermore, the spray composition according to the present invention is not limited by the effects described above. The spray composition according to the present invention can be modified in various ways without departing from the spirit of the present invention. [Examples]

[0044] The present invention will be further described below with reference to examples, but the present invention is not limited thereto.

[0045] [Preparation of low-viscosity galactoxyloglucan] Low-viscosity galactoxyloglucan exhibiting the viscosity shown in Table 1 was prepared by acid treatment of galactoxyloglucan (Griloid, manufactured by DSP Gokyo Food & Chemical Co., Ltd.) as described in Non-Patent Literature 1. Specifically, 272 g of 50% alcohol aqueous solution was placed in a pressure vessel, and 28 g of galactoxyloglucan was added and dispersed while stirring. Sulfuric acid was then added to adjust the pH of the solution to approximately 2. This solution was then heated to 110°C while stirring. After heating, sodium hydroxide aqueous solution was added to adjust the pH to approximately 7, and the solution was filtered to obtain a precipitate. Next, 300 g of 50% alcohol aqueous solution was added to this precipitate and stirred, and the solution was filtered to obtain a precipitate. Again, 300 g of 50% alcohol aqueous solution was added to the precipitate and stirred, and the solution was filtered to obtain a precipitate, which was then dried at approximately 75°C to obtain low-viscosity galactoxyloglucan. The heating time at 110°C was appropriately varied between 60 and 240 minutes to obtain low-viscosity galactoxyloglucan 1-8.

[0046] [Viscosity measurement] The viscosity of each low-viscosity galactoxyloglucan and galactoxyloglucan (Gliloid 6C) was measured. Specifically, 3 g of each sample was dissolved in 197 g of water with stirring to prepare a total of 200 g, and a 1.5% by mass aqueous solution was prepared. The viscosity of each aqueous solution was measured using a Type B viscometer (manufactured by Toki Sangyo Co., Ltd.) at 25°C and 30 rpm. The results are shown in Table 1.

[0047] [Table 1]

[0048] [Evaluation of the composition] Compositions were prepared according to the formulations shown in Table 2, and their sprayability, film-forming properties, and moisturizing properties were evaluated. The viscosity of each composition was also measured using a B-type viscometer at 25°C and 30 rpm. The results are shown in Table 2.

[0049] (Sprayability evaluation) The aqueous solution was filled into a spray container (Takeuchi Container Co., Ltd., Z-155 Fine Mist Spray), and the spray performance at 25°C was evaluated according to the following evaluation criteria. ◎: It forms a fine mist and spreads well. ○: It sprays out in a mist, but the spread is poor. ×: It becomes linear.

[0050] (Evaluation of film formation properties) The aqueous solution was placed in a plastic petri dish (90 mm in diameter, 15 mm in height) and dried at 50°C for 12 hours using a forced-air constant-temperature drying oven (Tokyo Rikakikai Co., Ltd., WFO-700). The formation and condition of the film after drying were checked, and the film-forming ability was evaluated according to the following evaluation criteria. ◎: Forms a flexible film. ○: Forms a hard coating. ×: Does not form a film.

[0051] (Moisture-retaining properties evaluation) An aqueous solution was filled into a spray container (Takeuchi Container Co., Ltd., Z-155 Fine Mist Spray), and one pump was sprayed onto the skin. The moisturizing effect was then evaluated according to the following evaluation criteria. ◎: Provides a sufficient moisturizing effect. ○: I feel a moisturizing effect. ×: It doesn't provide enough moisture.

[0052] (comprehensive evaluation) We assigned points to each aqueous solution, with ◎ representing 3 points, ○ representing 2 points, and × representing 1 point. The total score was calculated for each aqueous solution. Solutions with a total score of 8 points or more were classified as examples, and those with a total score of 7 points or less were classified as comparative examples.

[0053] [Table 2]

[0054] As shown in Table 2, Comparative Example 1, which contained galactoxyloglucan (gliloid 6C), had poor sprayability, while Examples 1-8, which contained low-viscosity galactoxyloglucan, had good sprayability. In particular, Examples 1-6, in which the viscosity of the 1.5% by mass aqueous solution of low-viscosity galactoxyloglucan was 50 mPa·s or less, showed even better sprayability.

[0055] Next, as shown in Table 3, compositions were prepared by changing the concentrations of low-viscosity galactoxyloglucan and galactoxyloglucan (gliloid 6C), and evaluated in the same manner as above.

[0056] [Table 3]

[0057] As shown in Table 3, compositions containing 0.5 to 2.0% by mass of low-viscosity galactoxyloglucan (Examples 9 to 11) exhibited good sprayability and sufficient moisturizing properties. In particular, compositions containing 0.5 to 1.5% by mass of low-viscosity galactoxyloglucan showed even better sprayability.

[0058] Next, compositions were prepared by changing the concentration of glycerin, as shown in Table 4, and evaluated in the same manner as above.

[0059] [Table 4]

[0060] As shown in Table 4, compositions with a glycerin content of 2.0 to 30.0% by mass (Examples 12 to 17) exhibited good sprayability and sufficient moisturizing properties. In particular, compositions with a glycerin content of 2.0 to 25.0% by mass (Examples 12 to 16) showed even better sprayability.

[0061] Next, compositions were prepared by changing the type and concentration of the polyol, as shown in Table 5, and evaluated in the same manner as above.

[0062] [Table 5]

[0063] As shown in Table 5, even when the type of polyol was changed, each composition exhibited good sprayability and sufficient moisturizing properties.

[0064] Next, we evaluated the sprayability and moisturizing properties when low-viscosity galactoxyloglucan was applied to various applications.
