Description

[Technical Field]

[0001] The present invention relates to an external preparation. The present invention also relates to an external preparation for scalp or hair and a hair care method using the same. The present invention also relates to an external preparation for animal skin. [Background technology]

[0002] Conventionally, various topical preparations have been proposed as measures against skin and scalp troubles, thinning hair, hair loss, etc. These topical preparations aim to improve the symptoms by inhibiting the factors that cause skin troubles and hair loss.

[0003] Here, for example, male pattern baldness is strongly influenced by genetic factors, and although there is a theory that male hormones are responsible for its cause, abnormal sebum secretion, excessive dandruff, malnutrition, and insufficient blood flow to hair follicles are also considered to be factors.Therefore, in the prior art, for example, vascular endothelial growth factor (VEGF) has been focused on as a factor that improves scalp blood flow and exhibits hair growth and hair care effects.It is known that VEGF promotes hair growth by generating new blood vessels around hair papilla cells in the hair bulb at the tip of the hair root on the scalp, and also promotes hair papilla cells to proliferate and promote the production of VEGF, thereby making hair grow thicker and longer.

[0004] For example, Patent Document 1 discloses a technology relating to a VEGF production promoter having an excellent VEGF production promoting effect. This technology uses bee larvae as an active ingredient, which not only has an excellent effect on the proliferation of hair papilla cells but also has an excellent VEGF production promoting effect. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2020-002034 Summary of the Invention [Problem to be solved by the invention]

[0006] In the past, various external preparations have been proposed as measures for the trouble of skin and scalp, or the symptom of thinning hair and hair loss, but their effectiveness is insufficient or side effects occur.For example, when the female hormone that antagonizes male hormone is used as the external preparation for androgenetic alopecia, when the amount that can obtain the effect of improving symptoms is compounded, the side effects caused by female hormone may become a problem.

[0007] On the other hand, it is also possible to address symptoms such as thinning hair and hair loss by improving the scalp condition to an environment suitable for promoting hair growth. According to Patent Document 1, it appears possible to improve the scalp condition to an environment suitable for promoting hair growth while minimizing the occurrence of side effects. However, bee larvae, which are also known as health foods, are relatively expensive and require a lot of effort to process. Furthermore, the proliferation of reactive oxygen species in the skin can cause inflammation, leading to skin and scalp problems, and symptoms such as thinning hair and hair loss. However, there is still room for improvement in the technology for improving the skin condition through anti-inflammatory and antioxidant effects on the skin and improving the scalp environment to one suitable for promoting hair growth.

[0008] The object of the present disclosure is to provide a technology that improves the condition of the skin through anti-inflammatory and antioxidant effects on the skin, and that improves the scalp environment to one that is suitable for promoting hair growth. [Means for solving the problem]

[0009] The topical agent of the present disclosure contains paulownia powder obtained by crushing the trunk and / or root of paulownia.

[0010] Paulownia trunks and roots contain components such as tannin, paulownin, and sesamin. The topical agent of the present disclosure is made by pulverizing paulownia trunks and / or roots to produce paulownin powder, which effectively exerts the anti-inflammatory effect of paulownin.

[0011] The present disclosure can be understood as an external preparation for scalp or hair, in which the paulownia powder is mixed with a predetermined liquid and configured to be applied to a person's scalp or hair. In this case, the external preparation for scalp or hair may contain 5% by mass or more of the paulownia powder. This allows for a significant promotion of hair growth. Alternatively, the external preparation for scalp or hair may contain less than 20% by mass of the paulownia powder. This allows for the external preparation to be applied so that it adheres to the subject's scalp or hair.

[0012] The present disclosure can also be viewed as a hair care method using the above-mentioned topical agent for scalp or hair. Specifically, the hair care method of the present disclosure includes an application step of applying the paulownia powder mixed with the liquid to the scalp and / or hair of a subject, and an irradiation step of irradiating the paulownia powder applied to the scalp and / or hair of the subject with infrared rays. In this case, the irradiation step can involve irradiation with infrared rays for 3 minutes or more. This appropriately heats the paulownia powder, activating the anti-inflammatory effect of paulownin and thereby promoting hair care. Furthermore, in the application step, the whipped liquid containing the paulownia powder can be applied to the scalp and / or hair of the subject to a thickness of 2 centimeters or more.

[0013] Furthermore, the present disclosure can be seen as an external skin preparation for animals, which is configured as a solid soap containing the paulownia powder by mixing a predetermined alkaline agent and the paulownia powder with natural oils and fats in the above-mentioned external preparation. [Effects of the Invention]

[0014] According to the present disclosure, the anti-inflammatory and antioxidant effects on the skin can improve the condition of the skin, and on the scalp, can improve the environment to one that is suitable for promoting hair growth. [Brief explanation of the drawings]

[0015] [Figure 1] 1 is a flowchart showing the flow of the hair care method of the present disclosure. [Figure 2] This is a diagram for explaining a comparison of the hair condition on the top and front of the subject's head before performing the hair care method of the present disclosure and the hair condition one month after performing the hair care method of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, an external preparation for scalp or hair according to an embodiment of the present disclosure and a hair care method using the same will be described based on a drawing showing the flow of the hair care method of the present disclosure. The configurations of the following embodiments are examples, and the present disclosure is not limited to the configurations of the embodiments.

[0017] An external preparation for scalp or hair according to an embodiment and a hair care method using the same will be described with reference to Fig. 1. Fig. 1 is a flowchart showing the flow of the hair care method of the present disclosure. The external preparation for scalp or hair according to this embodiment is an external preparation containing paulownia powder obtained by crushing the trunk and / or root of paulownia, and is configured so that it can be applied to a person's scalp or hair by mixing the paulownia powder with a specified liquid.

[0018] In this flow, first, in S101, a step of producing an external preparation for scalp or hair is executed. In step S101, paulownia powder obtained by crushing the trunk and / or root of paulownia is mixed with a predetermined liquid to produce an external preparation for scalp or hair.

[0019] Here, the proliferation of active oxygen in the skin causes inflammation, which tends to lead to skin and scalp problems, as well as symptoms such as thinning hair and hair loss.

[0020] The present inventor has newly discovered that, in response to such symptoms, paulownia powder can be used as an external agent for the scalp or hair, and its anti-inflammatory and antioxidant effects can improve the scalp environment to one that is suitable for promoting hair growth.

[0021] Specifically, the present invention aims to improve the scalp condition and create an environment suitable for promoting hair growth by utilizing a technology that enables the anti-inflammatory effect of paulownia, one of the components contained in the trunks and roots of paulownia, such as tannin, paulownin, and sesamin, to be favorably produced. In other words, the present invention is a hair growth promoter containing paulownia powder obtained by crushing the trunks and / or roots of paulownia as an active ingredient. According to another aspect of the present invention, an extract of paulownia trunks and / or roots can be used as the active ingredient. The extract is obtained by crushing the paulownia trunks and / or roots to an appropriate size and extracting the crushed pieces with hot water or a hydrous organic solvent. The following is a specific explanation of the extract, taking paulownia powder as an example.

[0022] To achieve this, in step S101, paulownia trunk and / or root sawdust is further pulverized to a particle size of approximately 10 μm to obtain paulownia powder. This paulownia powder is then mixed with a specified liquid to produce a topical agent for the scalp or hair. The paulownia powder and the specified liquid are mixed so that the topical agent contains 5% by mass or more of paulownia powder. The liquid may contain foaming hair-washing cosmetics or paste-like hair cosmetics. Using paulownia powder in this manner effectively exploits the anti-inflammatory effects of paulownin, which is contained in the trunk and root of paulownia.

[0023] For example, when preparing a topical agent for the scalp or hair for one person, 3 g of paulownia powder is mixed with 30 g of liquid. Here, the liquid is, for example, a mixture of 10 g of foaming hair cleansing cosmetics and 20 g of water. When using such foaming hair cleansing cosmetics, the mixture of paulownia powder and the liquid is stirred for about 1 minute to create a whipped foam.

[0024] In the application step described below, the topical agent must be applied so that it adheres to the subject's scalp or hair. Therefore, the paulownia powder and the liquid may be mixed together so that the paulownia powder content is less than 20% by mass. This allows the mixture of paulownia powder and the liquid to be adequately lathered, even if the paulownia powder, which has a relatively small particle size, absorbs water, allowing the topical agent to be applied so that it adheres to the subject's scalp or hair.

[0025] Next, in S102, an application step is performed in which the paulownia powder mixed with the liquid, that is, the topical agent for the scalp or hair, is applied to the scalp and / or hair of the subject.

[0026] In step S102, the mixture of whipped paulownia powder and the liquid is applied to the scalp and / or hair of the subject to a thickness of at least 2 centimeters. This allows the topical agent for scalp or hair to be maintained in a suitable state on the scalp and / or hair of the subject even during the irradiation step described below, thereby allowing the anti-inflammatory effect of paulonin to be effectively exerted.

[0027] To prevent dripping, rolled cotton may be wrapped around the nape of the neck and face of the subject, and the subject's head may be wrapped in plastic wrap.

[0028] Next, in S103, an irradiation step is performed in which infrared rays are irradiated onto the paulownia powder applied to the scalp and / or hair of the subject.

[0029] In this step S103, the paulownia powder applied to the subject's scalp and / or hair is irradiated with infrared rays using a far-infrared heater for a period of 3 minutes or more, thereby suitably heating the paulownia powder and activating the anti-inflammatory effect of paulonin.

[0030] After step S103 is performed, the topical agent is applied to the subject's scalp and / or hair, and then lathered, and then rinsed off with water or hot water for about 5 minutes.

[0031] Furthermore, a hair care method using such an external preparation for the scalp or hair can improve the condition of the scalp through its anti-inflammatory and antioxidant effects, and can improve the scalp environment to one that is suitable for promoting hair care.

[0032] (Control Examples, Examples, Comparative Examples) Topical preparations were prepared according to the formulations in Table 1 below. Example 1 of the present disclosure is a topical preparation containing 9% by mass (3 g) of paulownia powder and 91% by mass of a liquid mixture of foaming hair-washing cosmetics and water (10 g of foaming hair-washing cosmetics, 20 g of water), while Example 2 of the present disclosure is a topical preparation containing 5% by mass (1.7 g) of paulownia powder and 95% by mass of a liquid mixture of foaming hair-washing cosmetics and water (10 g of foaming hair-washing cosmetics, 20 g of water). A control topical preparation containing no paulownia powder was also prepared. Furthermore, an external preparation was prepared as Comparative Example 1, which was a mixture of 3% by mass (1 g) of paulownia powder and 97% by mass of a liquid mixture of foaming hair cleansing cosmetics and water (10 g of foaming hair cleansing cosmetics, 20 g of water), and as Comparative Example 2, which was a mixture of 20% by mass (7.5 g) of paulownia powder and 80% by mass of a liquid mixture of foaming hair cleansing cosmetics and water (10 g of foaming hair cleansing cosmetics, 20 g of water). Note that the above formulations are for producing an external preparation for the scalp or hair per person. [Table 1]

[0033] (Evaluation of topical preparations for scalp or hair) The topical preparations for scalp or hair prepared with the formulations in Table 1 above were evaluated according to the following evaluation method. The following evaluation of hair growth promotion was based on the irradiation step of the above-mentioned hair growth method, in which paulownia powder applied to the evaluator's scalp and / or hair was irradiated with infrared rays for 5 minutes.

[0034] (Evaluation of hair growth promotion) The hair growth promoting effect of the topical agent for scalp or hair in this embodiment was evaluated according to the following items. The results are shown in Table 2. The evaluation results were obtained by carrying out the above-mentioned hair care method for three evaluators, and qualitatively comparing the hair condition one month later with the hair condition before carrying out the above-mentioned hair care method. ○: Significant hair growth promoting effect is observed △: A slight promotion of hair growth is observed ×: No hair growth promoting effect observed [Table 2] As shown in Table 2 above, Examples 1, 2, and Comparative Example 2, which contain 5% by mass (1.7 g) or more of paulownia powder as topical agents for the scalp or hair per person, exhibit a significant hair growth promoting effect compared to the control example that does not contain paulownia powder.

[0035] Here, Figure 2 is a diagram for illustrating a comparison of the hair condition of the top and frontal regions of one of the three evaluators before and one month after the hair care method was performed, where Figure 2(a) shows the hair condition before and one month after the hair care method was performed. In the comparison shown in Figure 2, the topical agent for scalp or hair prepared with the formulation of Example 1 was used.

[0036] As shown in Figure 2, the hair condition one month after the above-mentioned hair care method was performed (Figure 2(b)) shows that hair care is significantly promoted in the top and frontal regions compared to the hair condition before the above-mentioned hair care method was performed (Figure 2(a)). In more detail, before the above-mentioned hair care method was performed, the scalp was often exposed due to thinning hair caused by alopecia, and the hair was thin, whereas one month after the above-mentioned hair care method was performed, hair growth from the exposed pores was observed and the hair was thicker, showing that hair care was significantly promoted.

[0037] When the product prepared with the formulation of Comparative Example 1 was used as an external preparation for the scalp or hair, hair growth was not observed to the extent shown in Figure 2 above, but a slight promotion of hair growth, such as hair growth due to improved scalp environment, was observed.

[0038] (Evaluation of foaming of topical preparations) The foaming of the topical agent for scalp or hair in this embodiment was evaluated according to the following criteria. The results are shown in Table 3. The evaluation results are the consensus of three evaluators who performed the hair care method described above. In this case, the foaming of the topical agent can be evaluated by the state of the topical agent when a mixture of paulownia powder and a specified liquid (a mixture of 10 g of foaming hair washing cosmetics and 20 g of water) is stirred for about 1 minute. ○: Whip-like foam ×: Does not whip [Table 3] As shown in Table 3 above, in Comparative Example 2, which contains 20% by mass (7.5 g) of paulownia powder as a topical agent for scalp or hair per person, the topical agent does not foam up like a whipped cream. On the other hand, in Examples 1, 2, and Comparative Example 1, which contain less than 20% by mass of paulownia powder, the topical agents foam up like a whipped cream. In other words, in Examples 1, 2, and Comparative Example 1, the topical agents can be applied so that they adhere to the subject's scalp or hair.

[0039] (Control Examples, Examples, Comparative Examples) Infrared rays were irradiated onto paulownia powder applied to the scalp and / or hair of a subject for the time periods shown in Table 4 below. Specifically, Example 3 of the present disclosure is an example in which infrared rays were irradiated onto paulownia powder applied to the scalp and / or hair of a subject for 5 minutes, and Example 4 of the present disclosure is an example in which infrared rays were irradiated onto paulownia powder applied to the scalp and / or hair of a subject for 3 minutes. The control example is an example in which infrared rays were not irradiated onto the paulownia powder applied to the scalp and / or hair of a subject. Furthermore, Comparative Example 3 is an example in which infrared rays were irradiated onto the paulownia powder applied to the scalp and / or hair of a subject for 1 minute, and Comparative Example 4 is an example in which infrared rays were irradiated onto the paulownia powder applied to the scalp and / or hair of a subject for 2 minutes. [Table 4]

[0040] (Evaluation of infrared irradiation time) The infrared irradiation times shown in Table 4 were evaluated according to the following evaluation method. The following evaluation of hair care promotion is based on the application step of the above-mentioned hair care method, in which a topical agent containing 9% by mass (3 g) of paulownia powder and 91% by mass of a liquid mixture of foaming hair cleansing cosmetics and water (10 g of foaming hair cleansing cosmetics, 20 g of water) was used.

[0041] (Evaluation of hair growth promotion) The hair growth promoting effect of infrared irradiation on the topical agent for scalp or hair in this embodiment was evaluated according to the following items. The results are shown in Table 5. The evaluation results were obtained by carrying out the above-mentioned hair care method for three evaluators, and qualitatively comparing the hair condition one month later with the hair condition before carrying out the above-mentioned hair care method. ○: Hair growth promoting effect observed △: A slight promotion of hair growth is observed ×: No hair growth promoting effect observed [Table 5] As shown in Table 5 above, in Examples 3 and 4, in which paulownia powder was applied to the scalp and / or hair of the evaluator and irradiated with infrared rays for more than 3 minutes, a hair growth promoting effect was observed compared to the control example in which infrared rays were not irradiated.

[0042] In addition, in Comparative Example 3, in which the paulownia powder applied to the scalp and / or hair of the evaluator was irradiated with infrared rays for a relatively short period of time, no promoting effect on hair growth was observed.

[0043] Furthermore, in Comparative Example 4, in which the infrared irradiation time was longer than that of Comparative Example 3 but was less than 3 minutes, hair growth was not observed to the same extent as in Examples 3 and 4, but a slight promotion of hair growth, such as hair growth due to improved scalp environment, was observed.

[0044] The topical agent for scalp or hair and the hair care method using the same described above can improve the condition of the scalp through its anti-inflammatory and antioxidant effects, and can improve the scalp environment to one suitable for promoting hair care.

[0045] <Other variations> The above-described embodiment is merely an example, and the present disclosure may be modified as appropriate within the scope of the present disclosure. For example, the processes and means described in the present disclosure may be freely combined as long as no technical contradiction occurs.

[0046] For example, the topical agent of the present disclosure may be configured as a bar soap containing paulownia powder by mixing natural oils and fats with a predetermined alkaline agent and paulownia powder.

[0047] The skin of animals such as dogs and cats is thinner and more delicate than that of humans. Furthermore, while human skin is slightly acidic, the skin of animals such as dogs and cats is neutral to slightly alkaline.

[0048] Furthermore, the skin of animals such as dogs and cats is covered with hair, which makes it easier for bacteria to grow due to dirt, etc., and can cause odors.

[0049] In other words, while keeping the skin of animals such as dogs and cats clean can eliminate the cause of odor, when washing animals such as dogs and cats, it is necessary to take good care of their thin and delicate skin.

[0050] Therefore, the topical agent of the present disclosure may be a bar soap containing paulownia powder, which can be used as an animal skin topical agent. The weakly alkaline soap component can cleanse the skin of animals such as dogs and cats without irritating them, and the components contained in the trunks and roots of paulownia provide deodorizing and soothing effects to the skin of animals such as dogs and cats.
