Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic raw material in which a part of the hydroxyl group of a galactomannan hydrolyzate having a specific molecular weight is substituted with a cationic compound (hereinafter abbreviated as cationization) and a cosmetic containing the same. According to the present invention, it is possible to provide a cationized galactomannan hydrolyzate having a good affinity for hair and skin, and giving a smooth and good feeling upon use and after use.

[0002]

2. Description of the Related Art Conventionally, natural products and their derivatives have been commonly used as cosmetic raw materials, and cations of natural polysaccharides such as cellulose, starch and guar gum have been used in hair cosmetics, shampoos, rinses, creams and the like. . For example, JP-A-47-20635 reports the use of cationized cellulose, JP-A-60-42763, a cationized hydroxyalkyl starch, and JP-A-7-17825, the use of a cationized hydroxyalkylgalactomannan in cosmetics and shampoos. ing. Among the cationized natural polysaccharides, chloride [2-hydroxy-3-
(Trimethylammonio) propyl] guar gum and [2-hydroxy-3- (trimethylammonio) propyl] hydroxyethylcellulose (hereinafter abbreviated as cationized guar gum and cationized cellulose) have also been used in shampoos and hair cosmetics. ing. However, when these were used as conditioning shampoos and hair cosmetics, the finished feeling was not sufficiently satisfactory. For example, the cationized guar gum has a moist feeling and a soft feeling, but gives an unpleasant sticky feeling, and the conditioning effect cannot be expected if the added amount is reduced to suppress this. Also, the cationized cellulose gives a feeling of dryness and tingling during the drying process as a finished feeling, and has a problem in terms of preferable hair feel. Furthermore, these cationized polysaccharides had a high viscosity when prepared as an aqueous solution, and sufficient simplicity could not be obtained.

[0003]

DISCLOSURE OF THE INVENTION The present invention provides a cationized decomposed galactomannan as a cosmetic raw material having an excellent feeling in use, and a cosmetic using the same.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies in view of the above-mentioned problems, and as a result, as a cosmetic base having a good finished feeling, a low viscosity of an aqueous solution and easy handling,
Galactomannan was decomposed and further reacted with a cationized compound such as glycidyltrialkylammonium salt or hydroxypropyltrimethylammonium chloride, and it was found that the above problem could be solved by using a cationized decomposed galactomannan. . That is, the present invention relates to a cosmetic raw material obtained by substituting a part of the hydroxyl group in the molecule of a galactomannan decomposition product with a cationic compound, and a cosmetic using the same.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The source of galactomannan of the galactomannan hydrolyzate of the present invention is not particularly limited, and includes those derived from plants and microorganisms, and preferably from plants such as locust bean gum, cod gum and guar gum. Is used. The molecular weight of these galactomannans is about 310,000 for locust bean gum,
It is known that guar gum has a number of 200,000 to 300,000 (Kodansha "Integrated Polysaccharide Science" published on December 1, 1974).

[0006] The galactomannan can be decomposed by any method. For example, biodegradation methods using polysaccharide-degrading enzymes, fungi and fungi directly, chemical decomposition methods using acids, alkalis, etc. or high-speed stirring, physical decomposition methods using a shearing machine, etc. can be mentioned. Purification is performed by an appropriate method to adjust the molecular weight accordingly. Examples of the purification method include use of ultrafiltration, reverse osmosis membrane, chromatography and the like. Among these decomposition methods, the enzymatic decomposition method has a uniform molecular weight as compared with the chemical decomposition method and the physical decomposition method, and therefore does not require a step of adjusting the molecular weight after the decomposition, and is a particularly recommended method. The type and origin of this enzyme are not particularly limited, but β-mannanase derived from Aspergillus or Rhizopus is preferred. Galactomannan enzymatic degradation products can change the molecular weight by changing the reaction time of the enzyme, but when this is cationized and added to hair cosmetics such as shampoos and rinses, it is uncomfortable if the molecular weight after decomposition is too large. A sticky feeling is produced, and if the molecular weight is too small, a conditioning effect cannot be expected. Therefore, the molecular weight of the enzymatic hydrolyzate of galactomannan according to the present invention is usually 50% or more, preferably between 4500 and 35,000, more preferably 8000 to 24000.
It is desirable that 80% or more be distributed. This molecular weight can be measured by high performance liquid chromatography equipped with a gel filtration type column. For example, if the relationship between the molecular weight and the outflow time is determined using a commercially available polysaccharide having a clear molecular weight as a standard substance, and the galactomannan hydrolyzate is analyzed under the same conditions, the molecular weight can be easily measured.

The viscosity of a 10% aqueous solution in which the polysaccharide containing the molecular weight is dissolved is 5% when measured at 30 ° C. at 25 ° C. using a Brookfield viscometer.
Those that are ２０20 cps are preferred. The galactomannan hydrolyzate decomposed by such a method can be cationized according to a known method. For example, it can be carried out by adding a cationized compound to a decomposed galactomannan dried product or an aqueous or alcoholic solution or suspension in the presence of an alkali catalyst, causing a heating reaction, and neutralizing the reaction after completion. The cationized compound of the present invention refers to a compound that can make the product electrically positive by performing a substitution reaction with the hydroxyl group of a galactomannan degradation product, and the type thereof is not particularly limited, but is preferably Is glycidyl trialkyl ammonium salt and 3
-Halo-2-hydroxypropyltrialkylammonium salts such as glycidyltrimethylammonium chloride, glycidyltriethylammonium chloride, glycidyltripropylammonium chloride, glycidylethyldimethylammonium chloride, glycidyldiethylmethylammonium chloride and the corresponding bromides, iodides and 3-chloro-2-hydroxypropyltrimethylammonium chloride, 3-chloro-
2-hydroxypropyltriethylammonium chloride, 3-chloro-2-hydroxypropyltriethylammonium chloride, 3-chloro-2-hydroxypropyltripropylammonium chloride, 3-chloro-
In addition to 2-hydroxypropylethyldimethylammonium chloride and the corresponding bromides and iodides,
And quaternary ammonium compounds such as halides of compounds having an imidazoline ring. Illustrating a part of the structure of a cationized decomposed galactomannan into which these cationized compounds are introduced,

(Wherein R1, R2, and R3 are a hydrogen atom, an alkyl group or a benzyl group having 1 to 3 carbon atoms, R4 is a hydrogen atom or a hydroxyl group, and X ⁻ is an anion). It is not limited to this. If the content of nitrogen introduced by the cationization reaction is less than 0.2% by weight, when it is incorporated into a cosmetic, the affinity for skin and hair is lowered, and the effect is not exhibited. 5% by weight
Beyond this, a sticky feeling is produced, giving discomfort. The preferred range of the nitrogen content is 0.5 to 3.0% by weight based on the decomposition product of galactomannan. This nitrogen content can be determined by a measuring method such as the Kjeldahl method or the semi-micro Kjeldahl method. After the cationization reaction, neutralization is subsequently performed, and the type of the anion of Formula 1 or Formula 2 changes depending on the acid used at this time. Although this acid is not particularly limited, cationization-decomposed galactomannan is usually chloride because hydrochloric acid is used.In addition to inorganic acids such as sulfuric acid, nitric acid and phosphoric acid, organic acids such as acetic acid and citric acid can also be used. In such a case, the anion of Formula 1 or Formula 2 is sulfate, nitrate, phosphate, acetate, citrate, or the like. The method of using the cationized decomposed galactomannan is not particularly limited, but it is blended with a hair cosmetic or a skin cosmetic of a known formulation, and is preferably used for a shampoo, a rinse, a cleansing cream, a cleansing gel, or the like. Other components in the cosmetic using the cosmetic base of the present invention are not particularly limited. For example, ordinary cosmetic carriers, diluents, or surfactants, medium- and long-chain fatty acid esters, oily substances such as hydrocarbons, proteins and their hydrolysates, bases such as lanolin,
Lipids, fragrances, UV absorbers, humectants, hydrotropes, preservatives, antioxidants and the like can be used. Also, vitamins and other nutritionally or pharmaceutically active ingredients may be added.

The amount of the cosmetic base of the present invention varies depending on the use and the like, but is usually preferably used in the range of 0.1 to 10% by weight. If the amount is less than 0.1% by weight, the effect is not sufficiently exhibited, and if it exceeds 10% by weight, an unpleasant feel may be obtained. The cationized degraded galactomannan incorporated in cosmetics can be analyzed, for example, by the following method. The cosmetic is dispersed in water, fractionated with an organic solvent such as diethyl ether to remove oily components, and the aqueous layer is subjected to gel filtration chromatography to obtain a fraction having a molecular weight of 5,000 to 50,000. After concentration under reduced pressure, the residue is appropriately diluted by adding water to the residue, and when permeating by adding methylene blue powder and chloroform, the dye migrates to the chloroform layer to confirm the presence of cationized degraded galactomannan. Next, the present invention will be described in more detail by way of examples, but the present invention is not limited thereto.

Example 1 Citric acid was added to 900 parts of water to adjust the pH to 3.0. To this, 0.2 part of galactomannanase derived from the genus Aspergillus and 100 parts of guar gum powder were added and mixed.
The enzyme was allowed to act for 24 hours at 0-45 ° C. 90 after reaction
C. for 15 minutes to inactivate the enzyme. The clear solution obtained by removing the insoluble material by filtration was concentrated under reduced pressure (solid content: 20%), and then spray-dried to obtain 65 parts of a white powder of an enzyme-decomposed product of guar gum. The water-soluble dietary fiber content according to the enzyme gravimetric method was 90%. In addition, the viscosity of a 10% aqueous solution of an enzyme-decomposed product of guar gum was measured at 25 ° C. and 30 rpm using a Brookfield viscometer, and the result was 16 cps. Furthermore, the molecular weight of the guar gum enzymatic degradation product was 82% in the range of 8800 to 22000 as measured by high performance liquid chromatography using G3000PWX (Tosoh) as the column with water as the mobile phase.
At this time, amylose Ex-1 (molecular weight 2900, manufactured by Seikagaku Corporation) and amylose Ex-3 were used as the molecular weight standards.

(0000, Pharmacia), and a molecular weight range was determined from the outflow time of the enzymatically degraded guar gum product. It is known that the molecular weight of guar gum before decomposition is 200,000 to 300,000 in average molecular weight (Kodansha, “Under polysaccharide science”, published on December 1, 1974).

Example 2 Water 500 was added to a 500 ml four-necked flask equipped with a stirring device.
150 parts of methanol containing 5% was added, and 70 parts of the enzyme decomposition product of guar gum obtained in Example 1 was gradually added with stirring. Add 3g of sodium hydroxide and add 50g
Then, 30 parts of glycidyltrimethylammonium chloride dissolved in 30 parts of water was gradually added thereto, and the mixture was further reacted at 50 ° C. for 6 hours. After the reaction, the mixture was neutralized with 10% hydrochloric acid, filtered, and dried under reduced pressure to remove the solvent, thereby obtaining 105 parts of a cationically decomposed guar gum of the present invention. The nitrogen content of this cationized guar gum was 2.2% as measured by the semi-micro Kjeldahl method. Example 3 According to Examples 1 and 2, enzymatic degradation time of guar gum,
By changing the number of moles of the cationized compound, cationized decomposed guar gums having different molecular weights and nitrogen contents were synthesized. Table 1 shows the results. The molecular weight was analyzed by high performance liquid chromatography according to Example 1, and the molecular weight was shown in the range of the molecular weight including 80% or more of the main component.
