The present invention relates to a novel moisture retention polymer compound and, more particularly, to a moisture retention polymer compound which has an effect of preserving the moisture in the skin and is suitable for being used in an external preparation for skin.
As a compound having an effect of retaining the moisture of the skin, a moisturizer is often used in an external preparation for skin. Such a moisturizer is blended in an external preparation for skin for the purpose of preventing moisture from evaporating, controlling the moisture in the skin surface, and imparting a moist feeling as well as moisture. The moisture amount in the corneum layer of the skin is closely related to a protective function against a variety of outside stimuli, and plays an important role in anti-aging of the skin, and feelings such as a moist feeling and a smooth feeling. This moisture retention in the corneum layer is generally controlled by NMF (natural moisturizing factor) and sebaceous membrane, however, the function is decreased easily due to aging or outside stimuli. Therefore, it is important for an external preparation for skin, in particular, a cosmetic product, to replenish moisturizing components in the skin. Examples of the moisturizing component for replenishing moisture to the skin include, as components which are the same with or similar to components of the living body, amino acids, peptides, proteins, saccharides, polysaccharides, lipids and glycoproteins.
In particular, a wide variety of compounds are known as saccharides. Examples thereof include alginic acid, pullulan, dextrin, glycogen, mucopolysaccharide, hyaluronic acid, chondroitin sulfate, chitin, chitosan and cellulose. For example, JP-A-1999-180818 (“JP-A” means a publication of an unexamined Japanese paten application) discloses an external preparation for skin containing glycogen derived from a plant, JP-A-2001-89381 discloses an external preparation for skin containing mucopolysaccharide, JP-A-2002-145753 discloses a cosmetic product containing hyaluronic acid, and JP-A-1997-249520 discloses a cosmetic product containing cellulose or starch. However, these naturally-occurring polysaccharides are composed of multiple types of monosaccharides, and the composition ratios are not constant, nor are the structures, therefore it is difficult to control the quality. In addition, when used in an external preparation for skin, such a component often causes aggregation structure where components are inhomogeneously present, to thereby generate gelation or precipitation. Further, there are drawbacks that when such a preparation is applied to the skin, an unpleasant feeling, an offensive odor or the like may be imparted.
In addition, as moisturizing components, many types of synthetic polymers are known. Examples thereof include sodium polyacrylate, polyethyleneimine, polyethylene glycol, polyvinyl alcohol, polyvinyl pyrrolidone, polyacrylamide, polyacrylic acid, polymethacrylic acid, vinylpyridine, silicones and polyoxyethylene. JP-A-2000-143484 discloses water-containing cosmetic sheet containing polyacrylic acid, and JP-A-1997-124878 discloses a gel composition for cosmetic product containing polymer of acrylic acid. Since the molecular weight of synthetic polymers can be easy to control, polymers with various properties or forms can be produced. On the other hand, however, in the case where such a polymer is used in an external preparation for skin, such an external preparation for skin cannot be said to have a sufficient moisture retention property which is comparable to that of a naturally-occurring polysaccharide and a high affinity to the skin to impart sufficient moisture to the skin.
An object of the present invention is to provide an external preparation for skin which can impart moisture to the skin and can exhibit an appropriate viscosity and solubility. Generally, in an external preparation for skin, a wide variety of compounds such as compounds for imparting a moisture retention property and compounds for imparting viscosity are blended. However, due to difference in solubility between the compounds, separation, precipitation, crystallization or the like occurs, whereby properties of the external preparation for skin or feeling upon using the external preparation for skin is significantly decreased in some cases. Another object of the present invention is to provide an external preparation for skin comprising a polymer that can reduce or avoid these disadvantages.
The present inventors, as a result of intensive studies in order to solve the foregoing problems, found out that by producing a polymer having in a molecule a repeating structural unit that imparts a moisture retention property and further having a unit that imparts viscosity and/or a unit that imparts solubility and the like in the same molecule and blending such a polymer in an external preparation for skin, the external preparation for skin can provide moisture to the skin and further give a good feeling to the skin while retaining an appropriate viscosity and solubility, thus completed the present invention.

The polymer compound of the present invention is a polymer compound having a structural unit including a multi-branched polysaccharide derivative and a structural unit without a multi-branched polysaccharide derivative. With regard to the multi-branched polysaccharide derivative, the hydroxyl group OH of the multi-branched polysaccharide may be substituted by OR wherein R represents a hydrogen atom, a hydrocarbon having 1 to 30 carbon atoms, or a hydrocarbon having 1 to 30 carbon atoms and a hetero atom.
More specifically, it is a polymer compound having a multi-branched polysaccharide derivative either in the main chain or in the side chain.
As an example of the case where the main chain of the polymer compound is composed of a structural unit including a multi-branched polysaccharide derivative, a polymer obtained by reacting multiple hydroxyl groups in the multi-branched polysaccharide derivative with a dicarboxylic acid compound, a diisocyanate compound or the like can be exemplified.
In the case of a polymer compound having a structural unit including a multi-branched polysaccharide derivative in the side chain, for example, a multi-branched polysaccharide derivative may be bound through an appropriate spacer to the main chain of the polymer compound. Examples of the spacer include an organic group having 1 to 30 carbon atoms which may have a hetero atom. Examples of the hetero atom in such an organic group include oxygen, nitrogen, sulfur, silicon and phosphorous, and examples of the organic group including a hetero atom include organic groups which have a hydrocarbon group, carbonyl group, urethane group, peptide group, sulfonyl group, phosphate group or the like as part or the whole of the spacer.
More specifically, the one obtained by reacting the hydroxyl group of the multi-branched polysaccharide derivative with the carboxyl group of a polymer obtained by copolymerization of acrylic acid, methacrylic acid or the like, or with the isocyanate group of a polymer obtained by copolymerization of isocyanate ethyl methacrylate or the like can be exemplified.
Examples of the synthetic method of the polymer compound of the present invention include a method of performing condensation polymerization by mixing a multi-branched polysaccharide derivative with a compound having in the molecule two functional groups that react with a hydroxyl group. For example, by mixing a compound selected from dicarboxylic acids or diisocyanates (e.g., diisocyanate hexane), with a multi-branched polysaccharide at an appropriate ratio to react with each other, polyurethane polymer compound including a multi-branched polysaccharide in the main chain can be obtained.
In addition, a method of synthesizing a monomer including a polymerizable functional group and a multi-branched polysaccharide derivative, and performing condensation polymerization, radical polymerization, ionic polymerization, ring-opening polymerization, block polymerization or graft polymerization of this monomer solely or together with another monomer, etc. can be exemplified.
Further, a method of preparing a polymer having a functional group in advance and thereafter reacting a multi-branched polysaccharide derivative with the foregoing functional group to thereby bind with each other, for example, a method for obtaining a polymer compound having a multi-branched polysaccharide derivative in the side chain by mixing methyl methacrylate with isocyanate ethyl methacrylate at an appropriate ratio, obtaining a polymethacrylic acid copolymer by radical polymerization and reacting the hydroxyl group of a multi-branched polysaccharide derivative with the isocyanate group of the polymethacrylic acid copolymer, can be exemplified. However, the method is not limited to these methods.
The multi-branched polysaccharide constituting the skeleton of the multi-branched polysaccharide derivative of the present invention is a compound composed of one kind or multiple kinds of saccharides as the structural components. The structure is a dendritic structure having many branching points wherein three or more sites binding with adjacent saccharide molecules exist in one saccharide molecule having multiple hydroxyl groups. Generally, a polysaccharide that exists in a variety of types as a natural substance is a linear polysaccharide or a branched polysaccharide having not so many branching points, and both types have its main chain. A multi-branched polysaccharide is a compound wherein its main chain cannot be clearly distinguished due to presence of many branching points.
Examples of the saccharide constituting the multi-branched polysaccharide of the present invention may include, as a pentose, ribose and deoxyribose, and as a hexose, glucose, fructose and galactose.
As a production method of the multi-branched polysaccharide of the present invention, a conventionally known method can be applied. For example, as a production method by a chemical synthesis method, a production method of obtaining a multi-branched polysaccharide by polymerizing a derivative of a monosaccharide as a monomer can be exemplified. Examples thereof include, as disclosed in JP-A-2003-252904, a production method of obtaining a multi-branched polysaccharide by ionic polymerization using an anhydrosaccharide as a monomer.
In this case, examples of the anhydrosaccharide may include, for example, 1,6-anhydrosaccharide, 1,4-anhydrosaccharide, 1,3-anhydrosaccharide, 1,2-anhydrosaccharide, 5,6-anhydrosaccharide, etc., and a derivative thereof. Specific examples may include 1,6-anhydro-β-D-glucopyranose, 1,6-anhydro-β-D-mannopyranose, 1,6-anhydro-β-D-galactopyranose, 1,6-anhydro-β-D-allopyranose, 1,6-anhydro-β-D-altropyranose, 1,4-anhydro-β-D-ribopyranose, 1,4-anhydro-α-D-xylopyranose, 1,4-anhydro-α-L-arabinopyranose, 1,4-anhydro-α-D-lyxopyranose, 1,3-anhydro-β-D-glucopyranose, 1,3-anhydro-β-D-mannopyranose, 1,2-anhydro-α-D-glucopyranose, 1,2-anhydro-β-D-mannopyranose, 5,6-anhydro-α-D-glucopyranose, etc., and a derivative thereof.
In addition, as the ionic polymerization, cation polymerization and anion polymerization can be exemplified. Further, there is a production method of obtaining a multi-branched polysaccharide by using an animal, plant or microorganism, or by using a method of raising, cultivating or culturing it. In this case, a multi-branched polysaccharide with a desired branching degree can be directly used. However, as a method of producing a multi-branched polysaccharide whose branching degree has been increased, for example, by a production method as disclosed in JP-A-1996-41104, the branching degree can be increased so that a branched polysaccharide may become a multi-branched polysaccharide.

Hereunder, the present invention will be specifically explained with reference to the Examples, however, the present invention is not limited to these Examples.
Under a nitrogen atmosphere, 1,6-anhydro-β-D-glucopyranose (manufactured by Tokyo Kasei Co., Ltd., 13.0 g), dried propylene carbonate (manufactured by Aldrich Co., 12.5 ml) and 66% by mass of 2-butynyl-tetramethylene sulfonium hexafluoroantimonate (manufactured by Asahi Denka Co., Ltd., 65.8 μl) were charged into a schlenk tube which had been thoroughly dried. Then, this schlenk tube was placed in an oil bath, and the oil bath was heated to 100° C., whereby 1,6-anhydro-β-D-glucopyranose was well dissolved. Then, the temperature was raised up to 130° C., whereby polymerization was started while well stirring the mixture. After a 30-minute reaction time, the polymerization solution was poured into methanol to stop the polymerization. After the solvent was distilled off, reprecipitation was repeated with water and methanol. Further, dialysis was performed for purification, and by freeze-drying, a white powder of multi-branched polysaccharide A (5.3 g) was obtained. The yield was 41%. The structure of this multi-branched polysaccharide A was confirmed by 1H-NHR and 13C-NMR. In addition, the weight average molecular weight was 20,000 (the light scattering method) and the branching degree was 0.38.
The multi-branched polysaccharide A (1.0 g) obtained in the Example 1, 1, 8-diisocyanate octane (0.2 g) and dried pyridine (10 ml) were put into a flask which had been thoroughly dried, and reacted at 100° C. for 3 hours while well stirring. After the reaction, the reaction solution was poured into methanol, the solvent was distilled off, and reprecipitation was repeated with water and methanol. Then, by freeze-drying, a white powder of polymer compound B (1.1 g) was obtained. The 1% aqueous solution of this polymer compound B was transparent.
Under a nitrogen atmosphere, isocyanate ethyl methacrylate (manufactured by Showa Denko K.K., 204 mg), methyl methacrylate (manufactured by Aldrich Co., 903 mg) and azobisisobutyronitrile (AIBN, 50.8 mg) were put into a pressure-resistant flask which had been thoroughly dried, dimethylformamide (DMF, 10 ml) was added, and thoroughly dissolved by well stirring. Then, this flask was subjected to an operation of degassing under vacuum and introduction of dried nitrogen 5 times. Finally the flask was degassed under vacuum and sealed. Then, this flask was placed in an oil bath at 60° C. and reaction was performed for 20 hours. After the reaction, the flask was opened after the temperature was lowered sufficiently, then the reaction solution was poured into hexane. After the hexane was removed, a small amount of chloroform was added and the residue was dissolved, which was added to hexane again for reprecipitation. This reprecipitation operation was repeated, and the precipitation was recovered by filtration. Then by freeze-drying, a white powder of polymer C (1.07 g) was obtained. The yield was 97%. The structure of this polymer C was confirmed by FT-IR, 1H-NHR and 13C-NMR. In addition, the weight average molecular weight was 13,900 (GPC/THF, in terms of polystyrene).
The multi-branched polysaccharide A (1.0 g) obtained in Example 1, the polymer C (1.0 g) obtained in Example 3, and dried pyridine (10 ml) were put into a flask which had been thoroughly dried, and reacted at 100° C. for 3 hours while well stirring. After the reaction, the reaction solution was poured into methanol, the solvent was distilled off, and reprecipitation was repeated with water and methanol. Then, by freeze-drying, a white powder of polymer compound D (1.1 g) was obtained. The 1% aqueous solution of this polymer compound was transparent.
Emulsions having compositions as shown in Table 1 were prepared by conventional methods. Ten females of age 20-30 used the emulsions, and their feedbacks after using each emulsion is shown in Table 2. It was demonstrated that by using sample 1-1 containing the polymer compound D obtained in Example 4, a moist skin feeling could be maintained. In addition, a rough feeling sample 1-2 gave showed it slow solubility.
The emulsions having compositions as shown in Table 1 were applied on the flexor surface of the forearm of three females aged of age 30 to 40 twice a day, once in the morning and the other time in the evening for 7 days. The moisture levels in the corneum layer were measured and compared on the morning of the eighth day with a conductivity value determined through high-frequency inductance method by using an impedance meter (SKICON-200: manufactured by IBS Co., Ltd.) as an index, and the results were shown in Table 3. According to the results, by using sample 1-1 containing polymer compound D obtained in Example 4, enhancement in conductivity was observed, which indicated that the moisture in the corneum layer was increased to replenish the skin moisture.
The polymer compound of the present invention comprises a repeating structural unit which imparts a moisture retention property to an external preparation for skin and further comprises in the same molecule a structure imparting viscosity or solubility. By blending the polymer compound, an excellent external preparation for skin which imparts moisture to the skin, gives a good feeling to the skin and which is less likely to generate separation, precipitation and crystallization, can be provided.
