  Hereinafter, the best embodiment of the external application agent according to the present invention will be described.

  The external application agent according to the present invention comprises cats claw and shea butter as main components and is applied to the skin. That is, it contains 15 wt% to 50 wt% of an extract of cat's claw, as other components, and further contains shea butter.

  In this specification, the unit of the blending ratio is described as “wt%”, which indicates the blending ratio of each component when the total amount of the external application agent is 100 wt%. Please note that. The same applies to the description of the external application cream and the external application gel.

  The extract obtained from the bark of cat's claw (hereinafter referred to as “cat's claw extract”) includes six types of alkaloids: telopodin, isotelopodin, lincophilin, isolincofilin, mitrafilin, and isomitraphyrin. It is clear that it exists. In addition to these alkaloids, it has been confirmed that components such as quinovic acid glucoside, steroin, triterpenes and flavonoids are contained. These components are considered to exert analgesic effects, anti-inflammatory effects, immune enhancing effects and the like.

  Conventionally, many external coating agents containing a cat's claw extract have a low blending ratio of the cat's claw extract. However, as a result of research, the present inventor has confirmed that the effect of the above-described cats claw is enhanced when the content of the cats claw extract is increased. Furthermore, the present inventor formulated the cats claw extract in a high proportion and used it with shea butter interposed therebetween, so that the analgesic, anti-inflammatory and cosmetic effects were more effective than when each was used alone. It has been found that it can be obtained significantly higher. As a result of the study, the present inventors have found an external application agent that has a higher immediate effect and can maintain the effect by blending the cats claw extract with 15 wt% to 50 wt% and shea butter.

  That is, the cats claw extract cannot obtain an immediate effect when the blending ratio is less than 15 wt%. On the other hand, the higher the blending ratio of the catscrow extract, the more easily the effect of catscrow is exhibited. However, the upper limit of the blending ratio is 50 wt% in relation to the blending ratio of other components such as shea butter.

  Here, it is preferable to use a liquid extract as the cat's claw extract. It is preferable to obtain catscrow extract by mixing bark of catscrow with an organic solvent such as lower alcohol or hydrous lower alcohol.

  Shea butter is a vegetable oil collected from the fruit seeds of butyrospermum parkii inhabiting the savannah region. It has been clarified that shea butter contains components such as oleic acid, stearic acid, triterpene alcohol and the like, and can provide an antioxidant action, a skin moisturizing effect, and the like.

  And the compounding ratio of shea butter is preferably 2 wt% to 80 wt%. When the blending ratio of shea butter is less than 2 wt%, the synergistic effect obtained by using in combination with the cat's claw extract does not appear. On the other hand, the upper limit of the shea butter compounding ratio is 80 wt% in relation to the compounding amount of the cat's claw extract. The shea butter can be used in either liquid or solid form. In particular, when the dosage form is made into a cream, it is preferable to use a solid one because the viscosity at normal temperature can be appropriately maintained and the dosage form can be easily maintained. In addition, when the dosage form is a gel, it is preferable to use liquid shea butter because it is easily compatible with the gel base material.

  The dosage form of the external application agent of this invention is not specifically limited, It can be set as various dosage forms, such as cream, gel, emulsion, ointment, lotion, oil. In particular, creams and gels are preferable because they are easy to adjust to the skin after application. Here, an embodiment in which the external application agent is a cream type and a gel type will be described.

Externally applied cream: In the externally applied cream according to the present invention, one or more vegetable oils and fats selected from cocoa butter, avocado butter, almond butter, mango butter and the like are further added to the above-mentioned externally applied agent. Is. When these vegetable oils and fats are added, they maintain their viscosity as cream at room temperature and begin to dissolve at a temperature similar to human body temperature, so when applied to the skin, they become smoother and have a better feeling of use and moisturizing. The beauty effect such as is improved. When the blending ratio of these vegetable fats and oils is 0.1 wt% or more, the external application cream is easy to handle and the cosmetic effects such as moisturizing can be improved. On the other hand, the upper limit of the blending ratio of these vegetable oils and fats is 82 wt% considering the blending ratio of the cats claw extract and shea butter.

External Application Gel: The external application gel according to the present invention is obtained by adding a gel base material mainly composed of water, carrageenan, and xanthan gum to the above external application agent.

  As the gel base material, it is preferable to use an aqueous base material mainly composed of mineral water, carrageenan, and xanthan gum. This is because natural ingredients are easily mixed with the external application agent, and when the external application gel is applied to the skin, it has excellent permeability to the skin and is easily adapted to the skin. In addition, it is preferable to mix | blend a gel base material with 44 wt%-82 wt%. If the blending amount of the gel base material is less than 44 wt%, the effect of facilitating the familiarity with the skin cannot be obtained. On the other hand, the upper limit of the amount of the gel base material is 82 wt% in consideration of the amount of other active ingredients such as cats claw extract and shea butter.
