, - -i.1 1 f- c-) 1 HAIR NOURISHING AGENT AND PRODUCTION THEREOF

Field of the Invention

The present invention relates to a hair nourishing agent and the production thereof. More particularly, the invention relates to a hair nourishing agent comprising fermented products obtained by applying, for example, a mixture of lipase and proteinase or rice yeast on a substrate containing vegetable protein such as rice bran and vegetable lipid, and also to the production thereof.

Background of the Invention

T Ihe true mechanism of failing-out and growth of hair is t tic, be discovered. Chief causes of falling-out of hair, ho,ever, are generallv believed to be interruption in blood circulation, low metabolism, excessive male hormone, skin inflammation and allergies.

hair comprises the part protruding out of:zk-in and the part under skin. The hair bulb at the root of a hair, comprises tissue called papillar cells. Numerous capillaries surround a hair bulb and papillar cells take in nutrition from blood running in the capillaries, repeating cell divisions and growing the hair.

Hoever, if blood is not sufficiently supplied into the c e 11 S the cell divisional activity slows down, resulting in blockage to growth of the hair. Accordingly, it is often claimed indispensable for the growth of hair to promote blood circulation in the skin and activate the functions of the c ell S.

Hair follicle which surrounds a hair possesses enzyme called 5a reductase, which gets converted into 5a -dihydrotestosteron by combining with male hormone, which is then transported via blood vessels to papillar cells, slowing down the activity of adenylcyclase thereof and leading to slowing down of the cell divisions. As a result, the hair follicle gets gradually atrophied, and the hair becomes downy. leading to generationg of baldness.

As mentioned above as examples, there are a number of views on the mechanism of falling-out and growth of hair, though, none of them are established ones. Presently there are great many types of hair growers distributed on the market, claiming they contain substances which the distributors believe are effective according to their understanding of the mechanism, for instance, for promoting blood circulation in head skin and/or activating papillar cells. However, a hair agent which is truly effective on hair is yet to appear in the market.

Under such circumstances, the inventor of the present invention has continued a long and strenuous research and finally come up with the present invention of a hair nourishing agent which works excellently on hair, comprising fermented products obtained by applying, for example, a 2- mixture of lipase and proteinase or rice yeast on a substrate containing vegetable protein such as rice bran and vegetable lipid.

Summary of the Invention

In accordance with the present invention there are provided a hair nourishing agent comprising fermented products obtained by applying, for example, a mixture of lipase and proteinase or rice yeast on a substrate conLaining vegetable protein such as rice bran and vegetable lipid, and also the production thereof.

Said substrate may comprise anything that contains vegetable protein and vegetable lipid. Enzyme for the fermentation must possess the ability to decompose the vegetable protein and the vegetable lipid in the substrate.

Such enzyme may be lipase and proteinase. Other types of Pnzyme such as amylase mav be additionallly used.

The fermented products go through a filtering process hair nourishing agents of the present invention are thus ind 1 obtained. They are harmless to human body and show excellent effects in growing hair.

preventing hair from falling out as well as in Detailed Description of the Invention

The present invention will be more fully described in the following.

A substrate for producing a hair nourishing agent of the present invention may be anything that contains vegetable protein and vegetable lipid. It may be, for example, grain products such as rice bran, sake lees, wheat embryo buds, fusuma bran, whole buckwheat or whole barnyard millet, bean products such as soybeans, bean-curd refuse, soybean milk, adzuki beans, soybean flour or coffee grounds, or others such as yams, taros. tea grounds, honey, sesame, peanuts, lotus seeds, ashitaba, beefsteak plants, wakame seaweed or sea tangles. Rice bran, sake lees, fusuma bran, coffee grounds, wheat embryo buds, sesame, bean-curd refuse, soybeans and adzuki beans are especially preferred as they contain well- ballanced vegetable protein and vegetable lipid.

Enzyme to be used for fermentation of the present invention need be capable of decomposing both vegetable protein and vegetable lipid in said substrate. They may be lipase and proteinase and others such as amylase may also be additionally used. Besides lipase and proteinase, rice yeast which possesses functions of producing a variety of enzyme in a living body may also be utilized.

Lipase to be utilized for the present invention may be spermato lipase used in the acidic range which is contained in a variety of mold, yeast, microorganisms, humors, or enzyme taken from internal organs. More particularly, pancreas lipase, liver lipase, tubercle bacteria lipase, FIB lipase and hima lipase may be used.

Proteinase to be utilized for the present invention is preferred to be acidic at the most suitable PH. In this regard, pepsin, trypsin or chymotrypsin, not possessing any particular active base except amino acid residue of the enzyme itself and not requiring any particular reagent for enzymatic activities, may be utilized. Or most of enzyme or cathepsin found in vegetable enzyme and animal cells such as papain or ficin, which can be activated by a reducing agent such as hydrocyanate, ascorbic acid, cYsteine or glutathione, may also pepsin, be used.

The fermented products were found to also contain such amino acids as leucine, isoleucine, lysine, methionine, cystein, phenylalanine, tyrosine, threonine, tryptophan, valine, histidine. arginine, aspartic acid, alanine, glutamin acid, glycine. proline and celin.

As is clear from the results of the analyses, the fermented products obtained according to the present invention contain a variety of amino acids and fatty acids.

Amino acids are believed to function to give nutrition to papillar cells and fatty acids are believed to function to activate and expand capillary blood vessels, to supply hair with moisture to give a shining appearance as well as to inactivate 5a -reductase contained in hair follicle to prevent softening of hair. The components singly or in combination are believed to promote growth of hair as well. It should be noted that the fermented products also contain amino acids which include sulphur and Linsatulated fatty acids, both of which are believed to possess excellent effects on the growth of hair.

T 1he products obtained by fermentation by applying rice yeast on the substrate according to the present invention were found to contain in small quantity vitamin A, vitamin B; vitamin B vitamin B,, vitamin BI,, vitamin C, vitamin E, copper, iron, calLICiUM, phosphorus, purine, deoxyribonucleic acid, ribonuleic acid, adenine, guanine, uracil, cytosine and X ant h i ne fermented proteinase, in addition to the components confirmed in said products obtained using a mixture of lipase and since a variety of enzyme besides lipase and proteinase, such as amylase, glutaminase, cellulase and pectinase are produced in the rice yeast, decomposing not only the vegetable protein and vegetable lipid but also other components in the substrate. It is believed that such other components also help promote hair growth by synergism with said amino acids and fatty acids.

For preservation of the hair nourishing agents of the present invention, they may be refrigerated or boiled, however, there is no functional change or degradation of the effects of the hair nourishing agents.

In the following a description of a method -for producing the hair nourishing agent of the present invention is gi-ven. The method comparises steps of applying enzyme on a substrate containing vegetable Protein and vegetable lipid and of f 11 ter ing the fermented products thus obta i ned.

The fermentation is Performed under aquerous conditions. Lipase and proteinase or rice yeast which produces other enzyme such as amylase is used as enzyme. The lipase and the proteinase may be separately applied or applied tolyether in a form of a mixture. Said mixture.. can contain other enzyme such as amylase in order to promote decompositional function and to decompose other components in the substrate. It is preferred to apply 0.1;N ', of each enzyme in said mixture against the substrate of 100. In case of rice yeast, as the decompositional function of said yeast is weak compared with that of lipase or proteinase, it is better to add I w of rice yeast against 100 of the substrate.

The fermentation temperature is preferred to be room temperature or 35'C to 45'C, and as a buffer solution, pH 6 to 11 of hydrochloric acidcollidine, primary potassium phosphate-secondary potassium phosphate, hydrochloric acid-sodium Veronal, hydrochloric acid-trisaminomethane, hydrochloric acid-borax, boric acid-sodium carborate, hydrochloric acid-aminomethyl propane diol, ammonium choloride-ammonia, glycine-sodium hydroxide, boric acid-sodium hydroxide, hydrochloric acid-sodium dimethyIglycinate, sodium bicarbonate-sodium carbonate, borax-sodium hydroxide, borax-sodium carbonate, hydrochloric acid-sodium carbonate, secondary sodium phosphate-sodium hydroxide or the like can be used. Any combination or combinations of said substances may also be used in the form of a mixture.

The reaction time for the fermentation is preferably 5 to 10 hours under agitation. The completion of the reaction can be known, as for lipase, by giving a predetermined coloring matter as an indicator and checking the amount of the extricated fatty acids which are produced by hydrolysis of ester, or by electrical titration using alkali. When the above is not easily performed, use colorimetry for the alcohol extricated in hydrolysis. As for proteinase, use the ninhydrine colorimetry, which is colorimetry of amino acids W by the bluish matter produced as ninhydrine is heated. When i S not S 0 r e n s e n easily performed, use of the formol titration of is possible. This method is a utilization of the phenomenon of divergence of the titration curve for a -amino radical or imino radical under the existence of formaldehyde. For sterilization, autoclave sterilization is preferred.

A hair nourishing agent of the Present invention is obtained by adding water or alcohol to the fermented Products after having filtered said fermented products. The hair nourishing agent thus obtained can be used as it is, or can be mixed in hair lotion, hair cream, hair liquid, hair tonic, pomade, shampoo or rinse.

is possible to mix in the hair nourishing agent of the Present invention some components which are often used in the conventional hair growers such as blood facilitator, metabolism Promoter, anti-male hormone, anti-inflammatorv, anLi-allerg'v, moistener, anti-bacteria, andior refrigerant.

The,,. are, for example, tocopherol acetate, capronium chloride, carbonic acid 5as, hinokitiol, pantonyl ethylether benzoinate, gl,,,ceride Pentadecanate, vitamin H, ethynil estradiol, glyth.ylricinic acid, diphenylhydramin chloride, hyaluronic acid, Minisasanishiki extract, mononitro.guaiacol, Togarashi tincture, Shoukvo tincture, livdrocortiscne, diphenic hydramin chloride, D-Pantothenyl alcohol, salicylic acid, lactic acid, sodium lactate, menthol and the like.
