Description

The present invention relates to a xyloglucan-containing gel composition.

Conventionally, xyloglucan is known as one of polysaccharides. When such xyloglucan is dissolved in water, it results in a Newtonian fluid solution. The resulting xyloglucan-containing composition is used in various fields such as foods and cosmetics.

Conventional gel compositions sometimes have insufficient shape-retaining properties and often exhibit syneresis. Therefore, it is difficult to mold the composition into a desired shape, and it is not suitable for long-term storage. In addition, if the amount of syneresis increases (for example, 20% by weight or more) during the product sales period, the solution that has synergized from the gel composition foams in the container, which impairs the appearance of the product. It has been difficult to use in critical applications. Since xyloglucan does not gel by itself, there is a demand for a xyloglucan-containing gel composition with improved shape retention and suppression of syneresis (water retention).

In view of the above-mentioned problems, the present invention provides a xyloglucan-containing gel composition that has shape retention to the extent that it does not lose its shape during use and storage, and suppresses syneresis over time within a general expiration date. The task is to provide

The inventors of the present invention have investigated the above problems, and have found that the desired shape-retaining property and suppressed syneresis are obtained by containing at least one of water, xyloglucan, and sugars or alcohols. It has been found that a xyloglucan gel composition can be provided. In addition, the xyloglucan-containing gel composition further contains a water-soluble polymer, thereby improving the shape retention and remarkably suppressing syneresis of water from the gel composition over time. completed.

That is, the present invention provides the following xyloglucan gel composition.

The composition is a xyloglucan-containing gel composition that is a molded article molded into a desired shape, has shape retention, and is an external preparation (provided that it is an acid hair dye containing an acid dye). except for certain xyloglucan-containing gel compositions).
According to Item 1, the xyloglucan-containing gel composition comprises water, xyloglucan,
By containing at least one of sugars and alcohols, the shape-retaining property is enhanced and the syneresis is further reduced.
Section 2. 2. The xyloglucan-containing gel composition according to item 1, wherein the xyloglucan content is 0.5 to 10% by weight with respect to the total amount.

According to the present invention, there is provided a xyloglucan-containing gel composition that has shape retention to the extent that it does not lose its shape during use and storage, and suppresses syneresis over time within a general expiration date. .

A xyloglucan-containing gel composition of one embodiment of the present invention contains water, xyloglucan, and at least one of sugars or alcohols (hereinafter sometimes referred to as sugars and/or alcohols). are doing. By blending saccharides and/or alcohols with xyloglucan in this way, shape-retaining properties that do not lose their shape during use and storage are imparted.
Here, the term "shape retention" refers to the ability of the gel alone to maintain its shape without the need for a support material (or carrier material) such as a gel molding vessel for retaining the gel shape.

The xyloglucan is a nonionic polysaccharide composed of glucose and xylose, and has a basic structure in which xylose is attached as a side chain to a main chain in which glucose is β-1,4-linked. Also, as used herein, the term "xyloglucan" means both high-molecular-weight (naturally occurring) xyloglucan and low-molecular-weight xyloglucan.

High-molecular-weight xyloglucan is xyloglucan derived from natural products and has a molecular weight of about 50,000 to 1,000,000. Such high-molecular-weight xyloglucan can be obtained, for example, by extracting from the cell walls of higher plants such as peas, soybeans, poplars, rice, and bamboo shoots, tamarind seeds, and the like. In addition, high-molecular-weight xyloglucan can be extracted from plant tissues using water, or if it is difficult to extract with water, it can be extracted using an alkaline aqueous solution. It is preferable to extract using an alkaline aqueous solution regardless of whether or not it is possible to extract with water.

The high-molecular-weight xyloglucan obtained by such extraction may be further purified by alcohol precipitation, ion-exchange chromatography, various types of chromatography utilizing differences in hydrophobicity, affinity, etc., if necessary. good.

Such tamarind seed-derived xyloglucan (tamarind seed xyloglucan) can also be obtained as a commercial product (for example, DSP Gokyo Food & Chemical Co., Ltd. Gliloid, Gliate), and such a commercial product can be used. After dissolving in water and mixing ethanol or the like with this aqueous solution to separate and precipitate xyloglucan, it can be further purified and used.

Further, the high-molecular-weight xyloglucan may be partially degraded to lower molecular weights for easy utilization.

Low-molecular-weight xyloglucan is xyloglucan obtained by thus reducing the molecular weight of high-molecular-weight xyloglucan. Such low-molecular-weight xyloglucan can be obtained by physical methods (e.g., low-molecular-weight reduction using a homogenizer, etc.), chemical methods (e.g., low-molecular-weight reduction, such as by acid hydrolysis, etc.), enzymatic decomposition, etc., or by isolation/extraction from plants. , chemical synthesis, etc., can be obtained by known methods.

For example, when obtaining low-molecular-weight xyloglucan from tamarind seed xyloglucan by enzymatic decomposition, a plant tissue-disintegrating enzyme having β-1,4-glucanase activity is used, and the addition amount, pH, and temperature are adjusted according to the characteristics of the enzyme. , the enzymatic decomposition reaction can be carried out by appropriately setting the time.

When cellulase is used as the plant tissue disintegrating enzyme, for example, tamarind seed xyloglucan and 0.01 to 2.0 parts by weight of cellulase per 100 parts by weight of tamarind seed xyloglucan are added to water. and enzymatically reacted at pH 3-7 and temperature 35-60° C. for 3-96 hours. After completion of the reaction, the cellulase is deactivated and the reaction product is purified by a method such as chromatography to obtain low-molecular-weight xyloglucan having a molecular weight of 5,000 or less. Also, the side chain can be partially decomposed, and examples of the method (partial decomposition method) include enzymatic and chemical methods.

The xyloglucan may be either high-molecular-weight xyloglucan or low-molecular-weight xyloglucan, or a mixture of the two, or a mixture of xyloglucans derived from a plurality of types of plants. good too.

The amount of the xyloglucan compounded is usually in the range of 0.1% to 15% by weight, preferably 0.5% to 10% by weight, relative to the total amount of the xyloglucan-containing gel composition. It is preferably 0.5 wt% to 5 wt%, and even more preferably 0.8 wt% to 3 wt%.
If this amount is less than 0.1% by weight with respect to the total amount of the xyloglucan-containing gel composition, the gel strength tends to be low and shape retention tends to be difficult. %, the viscosity of the aqueous solution becomes too high before gelation after dissolving xyloglucan in water, and it tends to be difficult to mold it into a desired shape.
On the other hand, when the xyloglucan content is 0.1% by weight or more, the gel strength is sufficiently high, and when it is 15% by weight or less, the viscosity of the aqueous solution is prevented from becoming too high. It can be suppressed to facilitate molding into a desired shape.

The saccharide can enhance the gelling ability of the xyloglucan aqueous solution. Such sugars are not particularly limited as long as they can enhance the gelling ability. Examples of the sugars include triose (three-carbon sugar, e.g. glycerylaldehyde, dihydroxyacetone, etc.), tetrose (four-carbon sugar, e.g., erythrose, threose, erythrulose, etc.), pentose (five-carbon sugar, e.g., ribose, lyxose). , xylose, arabinose, aviose, ribulose, xylulose, etc.), hexose (sexose, such as glucose (glucose), mannose, galactose, idose, fructose, sovubose, etc.), heptose (septose, sedoheptulose, colyose, etc.) etc.), disaccharides such as sucrose, maltose, trehalose, and cellobiose, trisaccharides such as maltotriose, oligosaccharides such as galacto-oligosaccharides, and water-soluble polymers such as dextrin. substances, xylitol, sorbitol, mannitol, and sugar alcohols such as erythritol. Further, the sugar may be one type selected from these or a mixture of two or more types.
Among these, the saccharides preferably contain at least one or two selected from the group consisting of monosaccharides and oligosaccharides.

The alcohol can enhance the gelling ability of the xyloglucan aqueous solution. Such alcohols include alcohols and alcohol derivatives. Such alcohols are not particularly limited as long as they can enhance the gelability.
Examples of the alcohols include monohydric alcohols (e.g., methanol, ethanol, isopropanol, etc.), 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.), Examples include derivatives of polyhydric alcohols. Also, the alcohols may be one selected from these or a mixture of two or more.
Preferred examples of the polyhydric alcohol derivative include alkylene oxide addition polymers of dihydric to tetrahydric alcohols. Examples of alkylene oxides to be addition-polymerized include ethylene oxide (EO), propylene oxide (PO) and butylene oxide (BO).
Specifically, for example, the alkylene oxide addition polymer of dihydric to tetrahydric alcohol includes PPG-40 butyl [that is, POP (40) butyl ether] (commercially available such as "Unilube MB-370"), PPG-30. Buteth-30 [that is, POE (30) · POP (30) butyl ether] (commercially available such as "Unilube 50MB-72"), PPG-16 glyceryl ether (commercially available such as "Uniol TG-1000"), PPG- 24 glyceryl-24 ("Unilube 50TG-32" as a commercial product), PPG-25-polyethylene glycol-25 trimethylolpropane ("Unilube 43TT-2500" as a commercial product), PPG-14 diglyceryl ("Unilube DGP -950” etc.), PEG-5-PPG-65 pentaerythrityl (“Unilube 5TP-300KB” etc.) (both of which are manufactured by NOF Corporation).
Here, PPG represents polypropylene glycol, POP polyoxypropylene, POE polyoxyethylene, and PEG polyethylene glycol.
Sugar alcohols, which are a type of polyhydric alcohol, function as the sugars, but also function as alcohols, and preferred examples thereof include pentahydric to hexahydric alcohols such as sorbitol and mannitol. Preferred examples of these sugar alcohol derivatives include alkylene oxide addition polymers of sugar alcohols. Alkylene oxides to be addition-polymerized include EO, PO, BO and the like.
Specifically, POP sorbit (commercially available “Uniol HS-1600D” (manufactured by NOF Corporation), etc.), POE (10) methyl glucoside (commercially available “Glucam E-10” (Japan Lubrizol Co., Ltd. ), etc.), POP (20) methyl glucoside (commercially available “Glucam P-20” (manufactured by Nippon Lubrizol Co., Ltd.), etc.).
Although such sugar alcohols also function as the sugars, they are included in the alcohols in the present specification.

Among the alcohols described above, the alcohol preferably contains at least one or more selected from the group consisting of lower alcohols, polyhydric alcohols and sugar alcohols. Moreover, the alcohols are preferably butylene glycol, glycerin, and various methyl glucosides.

The blending amount of at least one of the sugars or alcohols is not particularly limited. The amount of glucan can be appropriately set depending on the degree of gelation of the composition containing glucan.
For example, the total amount of at least one of the sugars or alcohols is preferably 5% to 70% by weight, more preferably 10% to 10% by weight, based on the total amount of the xyloglucan-containing gel composition. 60% by weight, more preferably 10% to 50% by weight.
If the amount is less than 5% by weight based on the total amount of the xyloglucan-containing gel composition, the gel strength tends to be low and shape retention tends to be difficult. If it exceeds , the solubility of xyloglucan in water is greatly reduced, resulting in precipitation of xyloglucan, which tends to make it difficult to obtain a uniform gel composition.
On the other hand, when the amount is 5% by weight or more, there is an advantage of high shape retention, and when the amount is 70% by weight or less, separation of water over time is reduced.

The weight % of water is the remaining amount after subtracting the total amount of xyloglucan, sugars and/or alcohols, and optionally other components from 100%, and is not particularly limited. The weight percentage of such water is, for example, appropriately set according to these components, and can be set, for example, from 15 to 95 weight percent, preferably from 20 to 90 weight percent.

In addition to the above, the xyloglucan-containing gel composition can be further blended with a water-soluble polymer to improve the shape retention of the gel composition. The amount of syneresis solution can be greatly reduced.

It is not particularly limited as long as it can be hydrated with water. Examples of the water-soluble polymer include plant polymer, microbial polymer, animal polymer, synthetic/semi-synthetic polymer, and the like.
Examples of plant-based polymers include gum arabic, tragacanth gum, galactan, guar gum, carob gum, karaya gum, carrageenan, pectin, agar, quince seed (quince), algecolloid (cassou extract), starch (rice, corn, potato, wheat ), glucomannan, and the like.
Examples of microbial polymers include xanthan gum, gellan gum, curdlan, dextran, succinoglucan, pullulan, and sodium polyglutamate.
Animal polymers include gelatin and hyaluronic acid.
Examples of the semi-synthetic water-soluble polymer include starch-based polymers (e.g., carboxymethyl starch, methylhydroxypropyl starch, etc.), cellulose-based polymers (methylcellulose, ethylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose, sodium cellulose sulfate, , hydroxypropyl cellulose, carboxymethyl cellulose, sodium carboxymethyl cellulose, cationized cellulose, crystalline cellulose, cellulose powder, etc.), alginate-based polymers (eg, sodium alginate, propylene glycol alginate, etc.), and the like.
Examples of synthetic water-soluble polymers include vinyl polymers (e.g., carboxyvinyl polymer (carbomer), polyvinyl alcohol, polyvinyl methyl ether, polyvinylpyrrolidone, etc.), polyoxyethylene polymers (e.g., polyethylene glycol 20, 000, 40,000, 60,000 polyoxyethylene polyoxypropylene copolymers, etc.), acrylic polymers (e.g., polyacrylic acid, polyethyl acrylate, polyacrylamide, etc.), polyethyleneimine, cationic polymers, etc. be done.
The amount of the water-soluble polymer blended depends on the xyloglucan concentration (blended amount), the types and concentrations of sugars and polyhydric alcohols used in combination, and the types and concentrations of other optional ingredients such as cleansing ingredients and moisturizing agents. It can be set as appropriate and is not particularly limited. For example, the weight ratio of xyloglucan to water-soluble polymer is preferably xyloglucan:water-soluble polymer=1:10 to 50:1.
If the weight ratio is outside the above range, the effect of increasing the shape retention of the xyloglucan-containing gel composition and the effect of suppressing syneresis from the gel composition over time will tend to be difficult to exhibit, and the viscosity of the aqueous solution will increase. Too much and it tends to be difficult to mold it into a desired shape.
On the other hand, when the weight ratio is xyloglucan: water-soluble polymer = 1:10 to 50:1, the effect of increasing the shape retention of the xyloglucan-containing gel composition and the separation of water from the gel composition over time The effect of suppressing is easily exhibited, the viscosity of the aqueous solution does not become too high, and it becomes easy to mold into a desired shape.
Considering these points of view, a more preferable range is xyloglucan:water-soluble polymer=1:
2 to 20:1.
Preferred water-soluble polymers include sodium alginate, xanthan gum, hydroxypropylmethylcellulose, sodium polyacrylate, carboxyvinyl polymer, and cationized cellulose, which are relatively easily soluble in water.
