Description

[Technical Field]

[0001] The present invention relates to an anti-slip dispersant composition. [Background technology]

[0002] It is common for athletes in gymnastics, baseball pitching, bouldering, and other sports to apply anti-slip chalk to their fingers before participating in the sport. Magnesium carbonate is widely used as the main ingredient in this anti-slip chalk. Magnesium carbonate has excellent water absorption properties, so it is believed to absorb sweat from the palms of the hands and prevent slippage caused by sweat.

[0003] Anti-slip chalk is also sometimes used in strength training. By applying anti-slip chalk to the fingers, for example, it can improve friction against barbells and dumbbells, which can improve performance and concentration during strength training.

[0004] Generally, there are three main types of anti-slip chalk: powder, solid, and liquid. Powder anti-slip chalk has the advantage of being cost-effective. Solid anti-slip chalk also has the advantage of being easy to carry. Furthermore, both powder and solid anti-slip chalk have the advantage that you can start training immediately after applying them to your hands.

[0005] On the other hand, both of these methods have the risk of scattering fine powder and damaging the surrounding environment (see, for example, Patent Document 1). In addition to these anti-slip chalks, pine resin, honey, etc. are sometimes used, but these can lead to staining of various equipment, and so their use is prohibited in some sports facilities.

[0006] In recent years, the use of liquid anti-slip chalk has become widespread. Liquid anti-slip chalk is made by dispersing the above-mentioned magnesium carbonate or the like in an organic dispersant such as alcohol. In liquid anti-slip chalk, the magnesium carbonate penetrates deep into the wrinkles on the hands, while the organic dispersant such as alcohol has the effect of removing oils from the hands. Furthermore, depending on the type of organic dispersant, the heat absorption effect during evaporation can absorb the heat from the palm of the hand, allowing frictional force to be exerted for a long period of time.

[0007] Liquid anti-slip chalk has the advantage of making it easier to maintain a clean environment inside the gym, as it produces less fine powder and transfers less powder to various equipment.

[0008] One example of a liquid anti-slip chalk is a liquid anti-slip composition proposed (see Patent Document 1), which contains 100.0 parts by weight of magnesium carbonate, 130.0 to 400.0 parts by weight of water or a mixture of water and a water-soluble liquid with a boiling point of 100°C or less as component (A), 2.0 to 30.0 parts by weight of a water-soluble liquid with a boiling point of 170°C or more as component (B), and 0.0 to 3.0 parts by weight of a water-soluble polymer compound as component (C). This composition prevents the magnesium carbonate from scattering as powder when applied to equipment, etc. It also prevents scattering during sports or exercise because it does not become powder. Furthermore, it allows for the adjustment of friction and slipperiness without using edible ingredients and maintains that state. Furthermore, it can be easily washed off with water, and as a secondary benefit, it has a smaller volume than a powdered version. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Japanese Patent Application Publication No. 2019-026545 Summary of the Invention [Problem to be solved by the invention]

[0010] Here, when anti-slip chalk for sports is used or when honey or other ingredients are added to it, although the performance of the sport itself improves, it can stain various equipment and deteriorate the environment of the facility. For this reason, there is a demand for anti-slip chalk that improves the performance of various movements while not causing stains on various equipment, such as being easy to clean afterwards.

[0011] In this regard, although the composition described in Patent Document 1 has been proposed, even the composition described in Patent Document 1 still has room for further improvement in terms of functionality for users (usage feel, water absorbency, adhesiveness, ease of use, grip feeling).

[0012] The present invention has been made in view of the above problems, and an object of the present invention is to provide an anti-slip dispersant composition that is both hygroscopic and adhesive, and that is less likely to cause staining of various equipment in various facilities. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0025] First, although the following disclosure, diagrams, and / or claims may be described as being presented alone or in combination with one or more other aspects, the subject matter of the immediate disclosure is not intended to be so limited. That is, the immediate disclosure, diagrams, and claims are intended to encompass the various aspects described herein, each alone or in one or more combinations with each other. For example, even if the immediate disclosure describes and illustrates a first, second, and third embodiment in such a way that the first embodiment is described and illustrated specifically in conjunction with the second embodiment, or the second embodiment is described and illustrated only in conjunction with the third embodiment, the immediate disclosure and illustrations are not so limited and may include only the first embodiment, only the second embodiment, only the third embodiment, or one or more combinations of the first, second, and / or third embodiments, such as the first and second embodiments, the first and third embodiments, the second and third embodiments, or the first, second, and third embodiments.

[0026] The use of the phrase "or" in this text shall mean a "non-exclusive" arrangement unless expressly specified otherwise. For example, when we say "item x is A or B," we mean either: (1) item x is either A or B, but not both; or (2) item x is both A and B. In other words, the word "or" is not used to define an "exclusive" arrangement. For example, the "exclusive 'or'" arrangement for the statement "item x is A or B" requires that x be either A or B.

[0027] Additionally, the phrases "comprising at least one of" and "comprising at least one of the following," when used in conjunction with a system or element, mean that the system or element includes one or more of the elements listed after the phrase. For example, if there are three types of elements, element 1 through element 3, the phrases "comprising at least one of" and "comprising at least one of the following" are to be interpreted as any of the following structural arrangements: a device including the first element, a device including the second element, a device including the third element, a device including the first and second elements, a device including the first and third elements, a device including the second and third elements, or a device including the first, second, and third elements.

[0028] A similar interpretation is intended when the phrase "used in at least one of the following" is used in this context. Furthermore, as used in this context, "and / or" is used as a verbal conjunction to indicate that one or more of the listed elements or conditions are included or occur. For example, a device including a first element, a second element, and / or a third element is to be interpreted as any of the following structural arrangements: a device including the first element, a device including the second element, a device including the third element, a device including the first element and the second element, a device including the first element and the third element, a device including the second element and the third element, or a device including the first element, the second element, and the third element.

[0029] Specific embodiments of the present invention will be described in detail below, but the present invention is not limited to the following embodiments and can be implemented with appropriate modifications within the scope of the object of the present invention.

[0030] <Anti-slip dispersant composition> The anti-slip dispersant composition according to this embodiment (hereinafter also referred to as "anti-slip agent composition") is a liquid or paste-like composition that contains a hygroscopic powder and sugars. The dispersant composition according to this embodiment is an integrated liquid or paste-like composition that contains the hygroscopic powder and sugars. Therefore, there is little possibility that the hygroscopic powder or sugars will transfer from fingers to various equipment, and the various equipment is less likely to be soiled.

[0031] [Hygroscopic powder] In the anti-slip agent composition, the hygroscopic powder is used to absorb sweat generated on the fingers, thereby exerting frictional force on the surfaces of the fingers. The hygroscopic powder is not particularly limited as long as it is capable of absorbing sweat generated on the fingers. Examples of the hygroscopic powder include at least one selected from the group consisting of magnesium carbonate, aluminum hydroxide, talc, and fused silica. Among these, it is preferable to use magnesium carbonate and / or aluminum hydroxide, which are low in cost and easily available.

[0032] [Sugars] Furthermore, in the anti-slip agent composition, sugars play a role in providing adhesion between the surface of various substrates and fingers. However, when honey or the like, which has been conventionally used, is used as the sugar, it may be difficult to remove after adhering to various substrates. For this reason, sugars are used in the present invention instead of honey or the like. As the sugar used in the anti-slip agent composition according to this embodiment, sucrose and / or its hydrolysates (glucose, fructose), galactose, maltose, maltitol, ribose, xylitol, sorbitol, trehalose, palatinose, palatinit, lactose, cellobiose, glycogen, cellulose, starch, cyclodextrin, mucopolysaccharides, celluloses, pectin, gum arabic, agar, alginic acid, dextran, etc. are preferably used. Among these, sucrose and / or its hydrolysates are more preferably used, and a combination of sucrose and its hydrolysates is even more preferably used.

[0033] When sucrose and / or its hydrolysate is used in the anti-slip agent composition, these components have high solubility in water, so that they can be easily removed by wiping with a cloth containing water after use. In particular, fructose, among sucrose hydrolysates, has particularly excellent solubility in water, so that it can be easily removed even if it adheres to various equipment.

[0034] In this specification, the expression "and / or" means "the combination of two parallel phrases and one of three options collectively," following the JIS standard "JIS Z 8301: Format and Preparation Method of Standard Sheets." For example, the expression "A and / or B" means that it includes only A, only B, and both A and B.

[0035] The amount of sugar in the anti-slip agent composition is preferably 0.1 to 400 parts by mass per 100 parts by mass of the hygroscopic powder. From the viewpoint of further improving the adhesiveness of fingers to various equipment, the lower limit of the amount of sugar is more preferably 20 parts by mass or more, and even more preferably 100 parts by mass or more. Furthermore, from the viewpoint of keeping the cost required for producing the anti-slip agent composition below a certain level and facilitating removal of the anti-slip agent composition after use from various equipment, the upper limit of the amount of sugar is more preferably 350 parts by mass or less, and even more preferably 300 parts by mass or less.

[0036] In addition, the adhesiveness exhibited by the saccharide in the anti-slip agent composition also depends on the concentration of the saccharide in the anti-slip agent composition. Therefore, the anti-slip agent composition preferably contains 1 part by mass or more and 200 parts by mass or less of the organic dispersion medium described below per 100 parts by mass of the saccharide. From the viewpoint of increasing the fluidity of the anti-slip agent composition and facilitating application to fingers, the lower limit of the organic dispersion medium is more preferably 10 parts by mass or more, and even more preferably 40 parts by mass or more. Furthermore, from the viewpoint of further increasing the adhesiveness between various equipment and fingers, the upper limit of the organic dispersion medium is more preferably 80 parts by mass or less, and even more preferably 70 parts by mass or less.

[0037] [Organic acid] As described below, to obtain sucrose and / or its hydrolysates, it is preferable to add an organic acid to an aqueous solution containing sucrose and heat the aqueous solution to hydrolyze the sucrose. Here, the organic acid used for this hydrolysis can be a highly safe organic acid that does not erode the skin of the fingers. More specifically, examples of organic acids include monocarboxylic acids such as formic acid, acetic acid, and propionic acid; hydroxycarboxylic acids such as citric acid, malic acid, and lactic acid; and dicarboxylic acids such as oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, fumaric acid, and maleic acid. Among these organic acids, it is preferable to use at least one selected from the group consisting of citric acid, malic acid, and lactic acid. These organic acids are all used as food additives and are therefore highly safe. Therefore, even when incorporated into an anti-slip agent composition and applied to fingers, they do not erode the skin of the fingers or cause rough skin.

[0038] The amount of organic acid to be added may be determined depending on the amount of sugar to be added. For example, it is preferable to use 0.05 to 30 parts by mass of organic acid per 100 parts by mass of sugar to be used. In order to efficiently induce the hydrolysis reaction, the lower limit of the organic acid is more preferably 1 part by mass or more, and even more preferably 3 parts by mass or more. Furthermore, from the viewpoint of reducing irritation to the skin of the fingers, the upper limit of the organic acid is more preferably 25 parts by mass or less, and even more preferably 10 parts by mass or less.

[0039] [Organic dispersion medium] The anti-slip agent composition according to this embodiment is in a liquid or paste form. In order to improve the applicability of the anti-slip agent composition to fingers, the anti-slip agent composition preferably contains an organic dispersion medium. By containing an organic dispersion medium, the hygroscopic powder and sugars in a dispersed state can be distributed approximately uniformly on the skin of the fingers.

[0040] As the organic dispersion medium, it is preferable to use alcohols that are less irritating to the fingers. More specifically, examples of such alcohols include monohydric alcohols such as ethanol, isopropyl alcohol, butanol, and isobutanol. Among these, it is preferable to use at least one selected from the group consisting of ethanol and isopropyl alcohol. By using such organic dispersion medium, the hygroscopic powder can be uniformly applied deep into the wrinkles of the fingers. Furthermore, these organic dispersion mediums also serve to wash away oils from the surface of the fingers, thereby improving the friction between the fingers and various equipment. Furthermore, these organic dispersion mediums absorb the heat of evaporation as they evaporate, thereby lowering the surface temperature of the fingers and suppressing sweating from the surface of the fingers during movement.

[0041] The amount of organic dispersion medium used is preferably 1 part by mass or more and 100 parts by mass or less per 100 parts by mass of the hygroscopic powder. In order to adhere a sufficient amount of hygroscopic powder to fingers with fewer applications, the upper limit is more preferably 50 parts by mass or less, and even more preferably 35 parts by mass or less. Furthermore, from the viewpoint of improving the handleability of the anti-slip agent composition, the lower limit is more preferably 10 parts by mass or more, and even more preferably 20 parts by mass or more.

[0042] [Hygroscopic liquid] The anti-slip agent composition according to this embodiment may contain a hygroscopic liquid. When the anti-slip agent composition contains a hygroscopic liquid, the anti-slip agent composition absorbs moisture from the fingers, thereby preventing a decrease in the frictional force between the fingers and various equipment due to sweat. Examples of the hygroscopic liquid include polyhydric alcohols such as propylene glycol, ethylene glycol, glycerin, and sorbitol. The hygroscopic liquid also functions as an organic dispersion medium.

[0043] The amount of hygroscopic liquid used is preferably 1 part by mass or more and 100 parts by mass or less per 100 parts by mass of hygroscopic powder. In order to adhere a sufficient amount of hygroscopic powder to fingers with fewer applications, the upper limit is more preferably 50 parts by mass or less, and even more preferably 35 parts by mass or less. Furthermore, from the viewpoint of improving the handleability of the anti-slip agent composition, the lower limit is more preferably 10 parts by mass or more, and even more preferably 20 parts by mass or more.

[0044] [Other ingredients] In addition, a thickening stabilizer can be blended into the anti-slip agent composition according to this embodiment. By blending a thickening stabilizer, the dispersed state of the hygroscopic powder in the organic dispersion medium can be stabilized. Examples of thickening stabilizers include pectin, guar gum, xanthan gum, tamarind gum, carrageenan, and carboxymethyl cellulose. Among these, it is particularly preferable to use xanthan gum.

[0045] [Other ingredients] The anti-slip agent composition according to this embodiment may further contain other additives depending on the intended use. Specific examples include preservatives (parabens, phenoxyethanol, benzoic acid, etc.), colorants, fragrances, stabilizers, and dispersants. The amounts of these additives may be those commonly used in the field of various compositions to be applied to the body.

[0046] [Uses of the anti-slip composition] The anti-slip agent composition according to this embodiment is versatile and can be used in a variety of sports, such as gymnastics, throwing events in track and field, bouldering, handball, and strength training, as well as in e-sports, physical labor sites, playing musical instruments, distributing handouts to teachers, etc. In this sense, the anti-slip agent composition according to this embodiment can be used in any application in which the frictional force of fingers is important.

[0047] <Method of manufacturing anti-slip dispersant composition> The anti-slip agent composition according to this embodiment includes at least a step of adding a hygroscopic powder to an aqueous sucrose solution to obtain a mixture (mixing step), and a step of dispersing the mixture (dispersing step). More preferably, the anti-slip agent composition includes a step of adding an organic acid to an aqueous sucrose solution and heating the solution to at least partially hydrolyze the sucrose (hydrolysis step), a step of adding a hygroscopic powder and an organic dispersion medium to the at least partially hydrolyzed sucrose solution to obtain a mixture containing the hygroscopic powder, the organic acid, sucrose and / or its hydrolysate, and the organic dispersion medium (mixing step), and a step of dispersing the mixture (dispersing step). The following describes the case where the anti-slip agent composition is obtained by the latter method.

[0048] [Heating process] In the heating step, an organic acid is added to an aqueous sucrose solution and heated to at least partially hydrolyze the sucrose. The lower limit of the heating temperature is, for example, preferably 40°C or higher, more preferably 50°C or higher, and even more preferably 55°C or higher. The upper limit of the heating temperature is, for example, preferably 100°C or lower, more preferably 80°C or lower, and even more preferably 70°C or lower.

[0049] [Mixing process] In the mixing step, the hygroscopic powder and the organic dispersion medium are added to the at least partially hydrolyzed sucrose solution to obtain a mixture containing the hygroscopic powder, the organic acid, sucrose and / or its hydrolysate, and the organic dispersion medium. These components may be added all at once, or each component may be added sequentially. Alternatively, to prevent the formation of agglomerates in the anti-slip dispersant composition and to obtain a uniform composition, each component may be added in small amounts in stages.

[0050] [Dispersion process] In the dispersing step, the mixture obtained in the mixing step is dispersed. In carrying out the dispersing step, various mixers, mills, etc. can be used to efficiently obtain an anti-slip dispersant composition in a highly dispersed state. [Example]

[0051] The present invention will be specifically explained below with reference to examples, but the present invention is not limited to these examples.

[0052] <Performance test of anti-slip agent composition> [Preparation of Anti-Slip Agent Composition] [Example 1] 6.6 g of magnesium carbonate (Kusaba Chemical Co., Ltd.) was added as a hygroscopic powder to 5 mL of a 100% aqueous sucrose solution, and the mixture was mixed and dispersed uniformly in a mixer for 1 minute. This gave an anti-slip agent composition according to Example 1. This anti-slip agent composition was in a liquid state.

[0053] [Example 2] A 100% aqueous sucrose solution was heated to 105°C to produce a syrup containing sucrose hydrolysate (glucose and fructose). The syrup was viscous. 6.6 g of magnesium carbonate (Kusaba Chemical Co., Ltd.) was added as a hygroscopic powder to 5 mL of this syrup, and the mixture was mixed and dispersed uniformly in a mixer for 1 minute. This produced an anti-slip agent composition according to Example 2. This anti-slip agent composition was in a liquid state.

[0054] [Example 3] A 100% aqueous sucrose solution containing 2.5% citric acid as an organic acid was boiled down to obtain a syrup containing sucrose hydrolysate (glucose and fructose). The syrup was viscous. To 30 mL of this syrup, 30 g of magnesium carbonate (Kusaba Chemical Co., Ltd.), 30 g of aluminum hydroxide (Kusaba Chemical Co., Ltd.), and 5 g of fused silica (Kusaba Chemical Co., Ltd.) were added as hygroscopic powders, 12 mL of 67% ethanol (Setsu Co., Ltd.), 2.5 mL of glycerin (Marugo Corporation), and 2.5 mL of propylene glycol (Marugo Corporation) were added as organic dispersion media, and 0.3 g of xanthan gum (Marugo Corporation) as a thickening stabilizer. The mixture was mixed and dispersed uniformly in a mixer for 1 minute. This produced an anti-slip agent composition according to Example 3. This anti-slip agent composition was in a paste form.

[0055] [Comparative test] Ten trampolinists were asked to apply 0.5 g of the anti-slip agent composition according to each Example or the following two comparative samples in the amounts shown below to the palms of their hands. After 1 minute and 10 minutes, they were asked to assume a curled-up position and grasp the shins of their feet with their palms. The functionality (feel in use, absorbency, stickiness, ease of use, and grip) was evaluated on a 10-point scale according to the following criteria.

[0056] [Comparative sample] Comparative sample 1: 0.5 g of powdered magnesium carbonate was applied to the hands and fingers, and then 0.5 g of 50% sucrose solution was applied to the hands and fingers. Comparative sample 2: 0.5 g of ethanol solution containing 25% magnesium carbonate is applied to the hands.

[0057] [Judgment criteria] 10: Demonstrates extremely good performance. 9: Very good performance 8: Very good performance 7: Excellent performance 6: Good performance 5: Performs slightly better 4: Demonstrate performance 3: Inferior 2: Slightly inferior 1: Completely inferior in performance.

[0058] [Results and Evaluation] The results are shown in Figure 1. As is clear from Figure 1, the anti-slip agent compositions of Examples 1 to 3 received higher ratings in all categories of usability, water absorbency, adhesion, ease of use, and grip, compared to Comparative Samples 1 and 2. The anti-slip agent composition of Example 2 received a higher rating than the anti-slip agent composition of Example 1, and the anti-slip agent composition of Example 3 received an even higher rating than the anti-slip agent composition of Example 2. Such ratings were observed even 1 minute after application to the fingers, but continued even 10 minutes after application to the fingers. These results demonstrate that the composition of the present invention is extremely useful as an anti-slip chalk.
