Abstract

PROBLEM TO BE SOLVED: To provide a shampoo having hair-loss-preventive and hair-growing effects and exhibiting new performance(s) as well.SOLUTION: A shampoo is such that: a shampoo base material has been incorporated with zinc pyrithione, dexpanthenol, nicotinamide, biotin and silas, and in addition, sophora angustifolia extract and at least one component selected from the group consisting of hinokitiol, green tea, aloe vera extract, mugwort extract and licorice extract.

Description

  The present invention relates to a shampoo, and more particularly to a shampoo that exhibits new performance in addition to a hair loss prevention effect and a hair nourishing effect.

  Conventionally, ingredients such as glycerin (humectant), fragrance, phenoxyethanol (preservative) were added to an aqueous solution such as sodium lauryl polyoxyethylene sulfate (surfactant) as a base material as a shampoo for washing hair. A shampoo is known (Patent Document 1 described later).

  Various studies have been made to select various additive components and satisfy the performance required for shampoos.

  However, although the shampoos known so far satisfy the required performance, no shampoo that can sufficiently prevent hair removal during or after washing has been proposed, and the hair nourishing effect has been insufficient.

  Accordingly, an object of the present invention is to provide a novel shampoo in which new required performance is added to the performance of hair loss prevention and hair restoration.

  That is, the present invention is a shampoo obtained by adding zinc pyrithione, dexpantenol, nicotinamide, biotin, and shirasu (especially volcanic ash shirasu) to a shampoo base material (for example, lauryl sulfate ester). It is related to. This shampoo is hereinafter referred to as “shampoo according to the first invention”.

  In addition, the present invention includes a shampoo base material (for example, lauryl sulfate ester-based) to which zinc pyrithione, dexpantenol, nicotinamide, and biotin are added, and further, Clara extract, hinokitiol, and green tea. And shampoo to which at least one selected from the group consisting of aloe vera, mugwort extract and licorice extract is added. This shampoo is hereinafter referred to as “shampoo according to the second invention”.

  In the shampoo according to the first invention, zinc pyrithione, dexpanthenol, nicotinamide and biotin are added to the shampoo base material, thereby preventing hair loss, hair restoration, skin activation, nutritional supplementation, and metabolism promotion. Can be planned. In addition, since shirasu is further added, pore cleaning and pore shrinkage can be achieved, and new required performance as a shampoo can be exhibited.

  Moreover, since the shampoo according to the second invention has added zinc pyrithione, dexpanthenol, nicotinamide and biotin to the shampoo base material, as in the shampoo according to the first invention, hair loss prevention, hair restoration, It can promote skin activation, nutrition, and metabolism. Moreover, since at least one selected from the group consisting of Clara extract, hinokitiol, green tea and aloe vera, mugwort extract and licorice extract is further added, hair loss prevention by reducing active enzyme, scalp Any of antibacterial activity, vasodilation, antibacterial action, tissue resuscitation, antipyretic / sedation, etc. can be achieved.

  In the shampoo according to the first invention, when a Clara extract is further added, there is an effect of preventing hair loss by reducing active enzymes.

  Moreover, in this shampoo, if at least one selected from the group consisting of hinokitiol, green tea and aloe vera, mugwort extract and licorice extract is further added, to the scalp as in the shampoo according to the second invention. Any of antibacterial activity, vasodilation, antibacterial action, tissue resuscitation action, antipyretic / sedation action, etc. can be achieved.

  Next, each component described above and its efficacy will be described in more detail.

  First, as a shampoo base material, among various surfactants, for example, lauryl polyoxyethylene (3) sulfate sodium salt (30% aqueous solution), lauryl sulfate sodium salt (30% aqueous solution), palm oleate Diethanolamine is used.

  Zinc pyrithione, dexpanthenol, nicotinamide, and biotin as basic components added to the base material are excellent in hair loss prevention and hair restoration effect. With these additions, the anti-dandruff component removes dandruff and itching, and the Kampo compound and active ingredients provide rich nutrition to the hair and scalp, creating a healthy scalp and elastic smooth hair. The effects of each of these additive components will be described individually below.

Zinc pyrithione solution:
Zinc pyrithione is a component often used in shampoos for hair loss prevention and treatment, and has an effect of preventing hair loss by suppressing DHT (dihydrotestosterone; a male hormone derivative). DHT acts on the hair follicles to make hair thin and weak, and consequently reduce the number of hairs, but zinc pyrithione fluid serves to directly prevent activation of this androgen derivative. It also suppresses dandruff-inducing bacteria, promotes protein and collagen synthesis, strengthens hair roots, regenerates and promotes cells, and keeps the scalp healthy.

Dexpanthenol:
Dexpanthenol is a precursor of vitamin B5 and is a component before becoming vitamin B5. This dexpantenol is absorbed into the skin and converted to vitamin B5, and then has the effect of increasing and activating the regeneration ability of the skin tissue. It is an essential substance for metabolism and synthesis of biological substances in the human body and is deficient. In some cases, it causes dermatitis, mucosal inflammation, and hair damage. Vitamin B5 is easily excreted even when taken, so it is more effective to apply it directly to the skin, and it is a very safe ingredient that can be used safely in infants, but this is dexpantenol shampoo ingredient It can be realized by using.

Nicotinamide:
A derivative vitamin of nicotinic acid, also called niacin, called vitamin B3. Dilates peripheral nerves and provides nutrition to the body. When deficiency occurs in the body, it causes pellagra dermatitis, glossitis, stomatitis, central nervous system symptoms, etc.

Biotin:
It belongs to the vitamin B complex, is also called vitamin H, and is a component necessary for the growth of many animals and plants. Biotin is an essential substance for the normal metabolism of fat and protein and promotes the treatment of psoriasis, alopecia, dandruff, seborrheic dermatitis, and grows strong nails and healthy hair.

  Shirasu, which is added to shampoo base materials, is a general term for white volcanic eruptions widely distributed in southern Kyushu and secondary deposits derived from them. They form a vast plateau around Kagoshima Bay. doing. Since this shirasu is rich in vitreous, it is called vitreous volcanic debris. Especially, when Shirasu is heated at a high temperature in an electric furnace and baked and foamed, it becomes a hollow glass sphere (shirasu balloon) having a size of 30 to 600 μm. Since the shirasu balloon has water and volatile components therein, the shirasu balloon is obtained by gasifying, foaming and expanding into a hollow body when heated rapidly within the softening temperature.

  Shirasu penetrates every corner of the pores on the skin surface, and its natural high-concentration mineral component cleans the pores, causing pore shrinkage, and effectively removing oils and fats attached to the skin's stratum corneum and skin, At the same time, since it is porous, it can adsorb particles of other shampoo additives mentioned above and move them to the surface of the skin, allowing them to penetrate into every corner of the pores on the surface of the skin where the skin comes into contact with moisture. it can. Then, when the shirasu comes into contact with the skin in water, the particles of the shampoo additive are separated from the shirasu and fixed on the surface of the skin, so that the performance can be sufficiently exhibited.

  This shirasu is preferably made of a volcanic ash shirasu, particularly a fine shirasu having a particle size of 10 μm or less (more particularly a very fine shirasu having a particle size of 2 μm or less). This is because the fine shirasu easily penetrates to every corner such as pores on the surface of the skin, and can effectively remove the horny layer of the skin and the oil and fat adhering to the skin.

  Such a fine shirasu is preferably obtained by pulverizing a volcanic glassy sediment with a pulverizer and atomizing it to a particle size of 10 μm or less, and a rotary sieve for selecting the particle size using centrifugal force. Therefore, it is preferable to make the particle diameter uniform.

  Since the surface of the fine shirasu is charged with negative ions, it also has an action of attracting and removing adhering impurities on the skin surface charged with positive ions. Since the fine shirasu is porous, it itself can reach the details of the surface of the object, and at the same time, it can fully exert its action while adsorbing and holding other additives. Further, since this fine shirasu emits far infrared rays, it has an effect of removing waste products on the skin surface.

  In addition, when Clara extract is used as another additive component, 5α-reductase activity is inhibited in the same manner as licorice extract described later. If the amount of 5α-reductase active enzyme increases, the DHT (dihydrotestosterone) hormone described above is secreted and hair loss proceeds, but this is prevented by the Clara extract.

  Hinokitiol has a very wide range of antibacterial activity, and thus provides antibacterial activity to the scalp.

  Green tea contains catechin and tannin components. Catechin suppresses the production of DHT (dihydrotestosterone), and tannin is effective in dilating the capillaries.

  In Aloe vera, the Anthraquinones component of Aloe has a strong antibacterial / antiviral effect on fungi, tetanus, epidermidis, Escherichia coli, plague, cholera, various causative bacteria and viruses. Aloe Vera's Monosaccharides and Polysaccharides ingredients give skin elasticity and relieve fine lines while smoothing. Aloe Vera has excellent efficacy as a non-oil moisturizer, moisturizes and softens the skin. Its salicylic acid component is a powerful analgesic / sedative and relieves itching and inflammation pain. Aloe's Auxins and Gibberellins components reinforce and regenerate and protect cellular tissues, that is, resuscitation of partial organisms. Aloe's polysaccharides and minerals, vitamin components and blood circulation promoting action nurture the ability to prevent inflammation.

  Artemisia extract is rich in vitamins such as vitamins A, B, C and D. The unique taste of mugwort is due to a component called cineol, which has antipyretic and sedative effects.

  The licorice extract contains β-Glycyrrhetinic acid, which inhibits 5α-reductase activity. If 5α-reductase activity enzyme increases, DHT (dihydrotestosterone) hormone is secreted and hair loss proceeds, but this is prevented by licorice extract.

  Next, the present invention will be described in more detail with reference to examples.

  First, the volcanic ash shirasu used in the shampoo of this example will be described. This volcanic ash was collected in the Yoshida area of Kagoshima, Japan and is called “Yoshida Shirasu” in Japan.

  This volcanic ash has the composition shown in Table 1 below, and is shown together with the efficacy (physiological characteristics and effects) of each component (% represents mass%).

  Looking at the above components, this volcanic ash contains natural highly concentrated mineral components, and these mineral components clean pores and exert pore shrinkage and exfoliation actions.

  Said Yoshida shirasu is refined after pulverizing volcanic ash to a predetermined particle size. Other volcanic ash can be used as long as it has the same action and function as Yoshida Shiras.

  Next, the shampoo which consists of a component of following Table 2 is shown with the effect of each component.

  Thus, the shampoo according to the present example is useful as a hair loss preventing and nourishing hair shampoo whose performance is improved by the action of the shirasu component.

  Of the components in Table 2, even the shampoo excluding the volcanic ash shirasu showed excellent performances shown in Table 2 above.

<Examples 1-5>
Next, Table 3 below shows examples of the content of each component of the shampoo according to the present invention (numbers represent mass%: hereinafter the same).

  And the composition of the shampoo by the example which changed content of said each component variously is shown in following Table 4.

  Table 5 below shows clinical results (number of questionnaire subjects: 20) regarding hair loss and hair growth for each shampoo of Examples 1 to 5.

<Examples 6 to 10>
Next, Table 6 below shows examples in which other components are added to the above components.

  And the composition of the shampoo by the example which changed content of said each component variously is shown in following Table 7.

  Table 8 below shows the results of questionnaires on the hair removal, hair restoration, and cleaning effects (number of questionnaire subjects: 20) for each shampoo of Examples 6-10.

  From each of the above results, hair loss prevention, hair nourishment, and even the cleaning effect changed depending on the content of volcanic ash shirasu, and good results were obtained at 0.5 to 1.0%, particularly 0.7%. Increasing beyond that did not give better results.

  In addition, the composition in Table 6 is more effective in preventing hair loss and the effect of nourishing than the composition in Table 4, or added with Clara extract, hinokitiol, green tea, aloe vera, mugwort extract, licorice extract However, it turns out that an effect improves a little about hair restoration and hair removal.

  INDUSTRIAL APPLICABILITY The present invention can provide a shampoo excellent in performance such as a cleaning effect in addition to a hair removal preventing effect and a hair nourishing effect.
