Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning agent useful as a facial cleanser, body soap, hair sham, and the like. [0002] In recent years, water pollution of rivers has become a serious problem, and alkali soap of vegetable oil fatty acid is considered to be preferable as a detergent component in view of its degradability.
However, when these alkali soaps are used, there is a problem that a firm feeling of the skin remains. In addition, when calcium ion or magnesium ion is contained in water, use of alkali soap generates metal soap and lowers the cleaning ability. On the other hand, in the human body, if one calcium ion exists in a cell, 1000
It is said that calcium is present in the individual and bone at a concentration gradient of 100 million, which is a healthy state. However, due to the lack of calcium intake in the Japanese diet, physiological functions work to maintain the above-mentioned concentration gradient, and calcium elutes from the bones into the blood, thereby maintaining a certain level in the blood and cells. At the concentration of calcium. JP-A-4-166290 discloses a water-soluble mineral-containing liquid obtained by pulverizing and mixing starch and / or cereal, seed and eggshell, hydrolyzing it, fermenting it, and filtering it. In this water-soluble mineral-containing liquid,
It has been reported that mineral ions are absorbed from skin cells along with the fragmented water because the water molecule population is fragmented and a single population of water molecules surrounds the mineral ions and disperses the mineral ions. . Therefore, development of a bath detergent containing calcium ions in a state of being absorbed from the skin is desired. SUMMARY OF THE INVENTION It is an object of the present invention to provide a detergent which contains calcium ions in a state of being absorbed from the skin, does not reduce the washing ability of alkaline soap, has good lathering, and has good lather removal. That is. [0005] The cleaning agent of the present invention is characterized by containing 0.01 to 30% by weight of a liquefied calcium phosphate compound. If the content of the liquefied calcium phosphate compound is less than 0.01% by weight, no effect is exhibited, and if it exceeds 30% by weight, the acid odor becomes remarkable and is not suitable for practical use. The content of the liquefied calcium phosphate compound is preferably 0.1 to 10% by weight, and 0.5 to 10% by weight.
More preferably, it is 5% by weight. The liquefied calcium phosphate compound used in the present invention comprises 1 to 80 parts by weight of a calcium phosphate compound having a Ca / P ratio of 1.0 to 2.0 and eggshell, and starch and / or cereal powder 10 to 50 parts by weight. It is a liquid obtained by fermenting and aging a pulverized mixture consisting of parts by weight. [0007] If the sum of the calcium phosphate compound and the eggshell exceeds 80 parts by weight, poor dissolution occurs and residues remain. On the other hand, if the amount is less than 1 part by weight, minerals at the time of liquefaction are small, and an active ingredient cannot be obtained. If the amount of starch and / or cereal powder is less than 10 parts by weight, the amount of organic acid produced is small, and the dissolving power of minerals decreases. If the amount exceeds 50 parts by weight, poor fermentation and residues are large, and the active ingredient cannot be extracted. [0008] The starch that can be used in the present invention is not particularly limited, and includes sweet potato starch, potato starch such as potato starch, corn starch and the like. There is no particular limitation on the cereal powder, for example, rice flour, flour,
Buckwheat flour can be used. As the calcium phosphate compound used in the present invention, various compounds can be used as long as the Ca / P ratio is 1.0 to 2.0. Examples of such compounds include hydroxyapatite and halogenated apatite. Examples include various apatites, monocalcium phosphate, dicalcium phosphate, tricalcium phosphate, tetracalcium phosphate, and the like, and these can be used alone or as a mixture of two or more. In order to produce the liquefied calcium phosphate compound used in the present invention, the above-mentioned raw materials are blended at a predetermined ratio, pulverized and mixed, and the obtained mixture is put into a fermentation tank. Water is added to 1 to 2 to 8, and the mixture is heated to 50 to 100 ° C. with stirring to gelatinize the starch, and then kept at 30 to 40 ° C. to form a viscous mixture. The mixture is kept at a temperature of 30 to 40 ° C., and a predetermined amount of koji mold or the like is added to carry out complex fermentation. Thereafter, the mixed fermented mixture is preferably aged for one to two months. The fermented ripened liquid thus obtained has an acid odor and contains organic acids produced by fermentation. The liquefied calcium phosphate-based compound thus obtained contains calcium ions and phosphate ions, and also trace amounts of mineral ions contained in the eggshell, and each of these ions is individually subdivided. It is finely dispersed in water surrounded by water molecules and is absorbed into skin cells together with the finely divided water. The detergent of the present invention contains the above-mentioned liquefied calcium phosphate compound together with a usual detergent component. The cleaning agent generally contains an alkali soap and / or various surfactants as a main component, and further includes a humectant, a foaming agent, a preservative, a coloring agent, a fragrance, a pearl agent, an emulsifier, a conditioning agent, and a thickener. Agents and the like are added. In the present invention, these common components can be blended. [0013] Alkali soaps include sodium soap and potassium soap. In the cleaning agent of the present invention, a surfactant can be used instead of or together with the alkaline soap as a cleaning component. The surfactant is not particularly limited, and various surfactants can be used. Specifically, for example, 2-alkyl-N
-Carboxymethyl-N-hydroxyethylimidazolinium betaine, an amphoteric surfactant such as alkyldiethylenetriaminoacetic acid, coconut oil fatty acid diethanolamide,
Nonionic surfactants such as alkyl polyoxyethylene ethers, anionic surfactants such as sodium α-olefin sulfonate and sodium alkylbenzene sulfonate, and cationic surfactants such as alkyltrimethylammonium halide. Or as a mixture of two or more. Examples of the humectant include glycerin and propylene glycol, and these can be used alone or as a mixture of two or more. Examples of the foam increasing agent include an alkyl sulfate, an amine oxide and the like. Examples of the preservative include an alkylpyridinium salt, benzoic acid, and an alkyl ester of p-hydroxybenzoic acid. As the pearl agent, ethylene glycol distearate or the like is usually used. Examples of the emulsifier include fatty acid glycol esters and the like, examples of the conditioning agent include glyceride, and examples of the thickener include polyvinyl alcohol. The cleaning agent of the present invention can contain various components as described above, but the mixing ratio can be varied widely depending on the use. The body soap preferably has the following composition. Alkali soap 20.0-50.0 parts by weight Liquefied calcium phosphate compound 0.01-30.0 parts by weight Amphoteric surfactant 5.0-20.0 parts by weight Nonionic surfactant 1.0-5. 0 parts by weight Moisturizer 1.0 to 15.0 parts by weight Coloring agent, perfume proper amount Preservative, chelating agent proper amount Pearl agent proper amount purified water residue [Action] By adding a liquefied calcium phosphate compound, a detergent is obtained. Despite the presence of calcium ions, metal soap is not produced because it is present as a monomolecular liquid metal, but rather the washing ability is improved, and fine foaming and foam removal are improved. Also,
It does not give a firm feeling to the skin after washing and gives a moist feeling. Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto. Example 1 (1) 20 parts by weight of potato starch and an average particle size of 4 μm as raw materials for producing liquefied hydroxyapatite
m of hydroxyapatite powder and eggshell in a total amount of 30 parts by weight were mixed and pulverized. Next, this mixed powder is put into a fermentation tank, pure water is added three times to the mixed powder, and the mixture is stirred, heated to 80 ° C. for 2 hours to gelatinize the starch granules, and then maintained at 38 ° C. Then, a predetermined amount of Koji fungi was added to perform complex fermentation. At this time, the fermentation was promoted by aeration and light irradiation. The obtained fermented liquid was aged at a temperature of 10 ° C. or lower for 1.5 months. The liquefied hydroxyapatite thus obtained contained 10700 mg of calcium and 9280 mg of magnesium as mineral components in 100 g of this liquid. (2) Production of body soap The following components were mixed and stirred until uniform, and a body soap was obtained. Potassium soap 40 parts by weight 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine 10 parts by weight Coconut oil fatty acid diethanolamide 30 parts by weight Condensed glycerin 2.0 parts by weight Propylene glycol 5.0 parts by weight Ethylene distearate Glycol 0.5 parts by weight Liquefied hydroxyapatite produced in (1) 4.0 parts by weight Fragrance (citrus) trace amount Ion-exchanged water The total amount is 100 parts by weight. Example 2 A hair shampoo was manufactured by mixing and stirring the following components until uniform. Sodium α-olefin sulfonate (surfactant) 5.0 parts by weight Alkyl polyoxyethylene ether (foaming agent) 1.0 parts by weight Fatty acid glycol ester (emulsifier) 10 parts by weight glycerol (conditioning agent) 1.0 Parts by weight Polyvinyl alcohol (thickener) 0.5 parts by weight Benzoic acid (preservative) 0.1 parts by weight Liquefied hydroxyapatite produced in (1) of Example 1 2.0 parts by weight Ion-exchanged water 100 parts by weight Parts by weight. Comparative Example 1 Podisoap was produced using the same composition as in Example 1 except that liquefied hydroxyapatite was omitted. Comparative Example 2 The following components were mixed and stirred until uniform to prepare a hair shampoo. Zinc pyrithione 1.0 g Triethanolamine alkyl sulfate (detergent) 17.0 g Diethanolamide laurate (detergent) 3.0 g Ethanolamine (pH adjuster) 0.1 g Ethyl parahydroxybenzoate (preservative) 0.5 g Purified water 78.4g Fragrance trace amount The body soap and hair shampoo obtained in the above Examples and Comparative Examples were used by 50 persons with atopic dermatitis on the skin and scalp, and the following items were evaluated.
