Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facial cleanser containing hydroxyapatite,
The present invention relates to a hair wash and a bath agent.

[Conventional technology]

Through metabolism, the living body is constantly decomposing and synthesizing useful substances, and some of the waste products generated by these metabolisms are
It is released to the outside through the skin, hair, etc.
Hair and the like protect the living body by preventing the invasion of biological obstacles from the outside world. Therefore, skin, hair, etc. are always polluted by waste products of the living body and contaminants in the outside world. It is necessary to wash the contaminants and keep the skin, hair, etc. clean so that biological functions can be performed smoothly, because leaving these contaminants undisturbed keeps biological functions intact. It is an important factor in maintaining the skin's moisturizing effect, promoting metabolism, and keeping the skin warm and clean. Skin,
Soap, body shampoo, hair shampoo, rinse, bath agent, detergent (hereinafter referred to as toiletry products) are widely used for cleaning hair, maintaining function, bathing, and washing clothes. It is a well known fact. For cleansing the skin, it is required that the amount of free alkali is small, there is no skin irritation, it is moderately soluble in water, it has an excessive cleansing power, and it has a good feeling of use. As the alkali salt of higher fatty acid (soken) is used as. Soken is water-soluble, shows remarkable surface activity, produces stable bubbles, and has great detergency.It is usually blended with fragrances, pigments, antioxidants, sequestering agents, pigments, etc. Is marketed as. Soken has a strong surface activity and has a strong ability to emulsify and remove contaminants, so it has a great effect on the removal of contaminants such as fats and minerals that are not so strong in binding to the skin, and sometimes for moisturizing the skin. It may even remove the fat needed to cleanse the skin after washing. For this reason, cosmetic stones, body shampoos, etc. containing a skin protecting agent such as higher alcohol and fatty acid ester are also used. However, since protein waste such as keratin has a strong affinity for skin, hair, fibers, etc., it is difficult to effectively remove it by the washing action by the emulsifying power of soap. For this reason, a laundry detergent is mixed with a protease to improve the protein removing effect, but the use of the protease in the living body has not been performed because of problems in skin composition and soap production. Body shampoos and hair shampoos use the emulsifying action of surfactants and are based on the same principle as Soken, so they have the same drawbacks as Soken, and zinc pyrithione (Zpt ) Is used in the shampoo for shampooing. Due to its physical properties, Zpt has a limited amount and method of use and cannot be arbitrarily used, and a special technique is required for the production of shampoos containing it. Inorganic substances such as sodium sulfate, borax, and baking soda as bath agents are used for keeping the skin warm and moisturized, irritating (hereinafter referred to as activating action), and for cleaning, and salicylate, sulfide, etc. Is being used for. However, since these bath salt components are exogenous and toxic, their use is restricted.

[Problems to be Solved by the Present Invention]

As mentioned above, currently used toiletry products incorporate various problems. The object of the present invention is to efficiently remove protein-based contaminants that do not cause the drawbacks of conventionally used toiletry products, and be safer for living organisms,
An object of the present invention is to provide a toiletry product that effectively removes unnecessary contaminants without impairing the functions of the skin, hair, etc. and effectively acts on skin activation.

[Means for Solving the Problems]

Hydroxyapatite, which is the main component of bone and is used as an excellent calcium agent, is a harmless substance and strongly adsorbs various chemicals, especially proteins, so it can be used as an adsorbent for various chemicals, such as separation and purification of substances, enzymes. Widely used for immobilization. We believe that hydroxyapatite has a keratin softening action, has the ability to adsorb and remove old keratin with a strong adsorption force, and also has a skin activating action,
Therefore, it was confirmed that by preparing a toiletry product containing hydroxyapatite, a toiletry product without the drawbacks of the conventional toiletry products can be obtained. By blending hydroxyapatite with conventional toiletry products, hydroxyapatite efficiently adsorbs and removes old keratin and other protein contaminants, removing only unnecessary contaminants and effectively acting on skin activation. available. That is, the present invention provides a hydroxyapatite-containing toiletry product obtained by blending hydroxyapatite with a surfactant and a chemical which have been conventionally used for toiletry products.

The hydroxyapatite used may be bone powder or synthetic product, but it is desirable that it be as fine as possible.
Fine powder using an ultra-fine crusher such as a set mill, micron mill, colloid mill, or polyester, polyethylene, nylon, or other spherical polymer particles, with hydroxyapatite fine powder silicon acrylic emulsion, urethane The mixture is mixed at a temperature of about 20 ° C. to about 80 ° C. in the presence of a binder such as an acrylic emulsion, and hydroxyapatite fine powder is attached to the surface of the polymer spheres for use. The smaller the particles of hydroxyapatite used, the more stable the suspension will be, so the preparation of toiletry products will be easier, but if the particles are too fine, the size of hydroxyapatite may be taken up by the body. In consideration of the reflectance and the refractive index, it is desired that the thickness is about 3 to 10 μm. Ingredients conventionally used hydroxyapatite particles thus prepared in toiletry products, such as soap, sodium alkyl ether sulfate, diethanolamine laurate, triethanolamine alkyl sulfate, coconut fatty acid monoethanolamine, ethylene glycol monostearate , Polyacrylic acid triethanolamine, cation-modified cellulose ester, stearyl dimethylbenzyl ammonium chloride, stearyl trimethyl ammonium chloride, polyoxyethylene cetyl ether, polyoxysilanoline ether, polyoxyethylene cholesterol, propylene glycol, stearyl alcohol, glycerin monostea Rate, isopropyl myristate, lanolin fatty acid isopropyl, mineral oil, paraoxy Ikikosan esters, other surfactants such as, obtaining alcohol, esters, etc. and preservative fungicides, antioxidants, dyes, perfumes, oils, a mixed hydroxyapatite containing toiletries according to other and purpose. The addition ratio of hydroxyapatite is not particularly limited, but since the surface activity of the toiletry product obtained by containing hydroxyapatite decreases, it is necessary to determine the content of hydroxyapatite in relation to the required surface activity. Generally, the content of hydroxyapatite is about 1: 1 to 1: 0.01, preferably about 1: 0.6 to 1: 0.05 by weight ratio of hydroxyapatite to surfactant. The compounding and mixing are easily performed by a conventional method. For example, hydroxyapatite is uniformly mixed with a surfactant, and the mixture containing other organic components is diluted with water. The resulting hydroxyapatite-containing toiletry products shine like pearls because the hydroxyapatite itself is fluorescent white.

[Action]

Toiletry products containing finely pulverized hydroxyapatite have a strong adsorption ability of hydroxyapatite, keratin softening action, and skin activating action to efficiently adsorb and remove protein contaminants and old keratin, and activate the skin. Compared with other toiletry products, it efficiently removes protein contamination of skin and hair and activates the skin. Also, since the presence of hydroxyapatite reduces the emulsifying power of the surfactant,
The disadvantages of the conventional toiletry products caused by excessive emulsification of fats and minerals do not occur. In addition, it is easy to adjust the emulsifying power by washing the ratio of hydroxyapatite and surfactant arbitrarily.

The present invention will be specifically described below with reference to examples.

All of the toiletry products described below mix finely hydroxyapatite and a surfactant organic component heated to 50 to 60 ° C in a crusher uniformly with stirring, and then dissolve the organic component or inorganic substance in water. While vigorously stirring the melted aqueous solution, the surfactant and the organic component containing hydroxyapatite obtained by stirring and mixing are gradually added, and after the addition is completed, stirring is continued for 30 times to obtain a product. The numerical value shown in the example is g.
