  However, the cosmetics containing the above-mentioned conventional and proposed plant ingredients have their advantages and disadvantages, moisturizing effect and its durability, feeling of use, compatibility between plant ingredients and other cosmetic ingredients, stability, washing removal None of the materials, material costs, productivity, etc. could be satisfied.

  In view of the above-mentioned circumstances, the present invention is a cosmetic containing a plant component, which has excellent moisturizing effect and its sustainability, good usability, and compatibility and stability of the plant component with a general cosmetic component. The purpose is to provide a product that has good characteristics and can be mass-produced at low cost.

  In order to achieve the above-mentioned object, the cosmetic according to the invention of claim 1 includes a plant component of the genus Dioscorea.

  According to a second aspect of the present invention, in the cosmetic of the first aspect, the plant component is a stalk juice or an extract.

  According to a third aspect of the present invention, in the cosmetic of the first aspect, the plant component is an extract of persimmon.

  According to a fourth aspect of the present invention, in the cosmetic of the first aspect, the plant component is composed of a mixture of a koji extract and a stem juice.

  According to the invention of claim 1, since the plant component of the genus Dioscorea spp. Is included as a cosmetic, it continuously exhibits a high moisturizing effect based on a peculiar sticky component mainly composed of its glycoprotein mucin. It is easy to use with a moist and soft touch, and the plant component has good compatibility and stability with common cosmetic ingredients. What you can do is provided.

  And in the structure of Claim 2 which uses the juice of a stem or an extract as a plant component in the cosmetics of the said Claim 1, especially strong moisturizing effect is acquired, and in the structure of Claim 3 which uses the extract of a strawberry A gentle moisturizing effect that reduces skin irritation. Furthermore, in the structure of Claim 4 which uses the mixture of the extract of strawberry and the juice of a stem as this plant component, since properties, such as a moisturizing effect and irritation, can be adjusted with the mixture ratio of both, It can provide cosmetics that match the conditions and preferences.

  Plants of the genus Dioscoreaceae that are blended in the cosmetics of the present invention as plant components (hereinafter simply abbreviated as Dioscorea) are broadly classified into three types: natural moths, long-nosed moths, and large potatoes, all of which are used. it can. Among them, natural selection is a thin and winding thing that grows naturally in Japanese mountains since ancient times, but in recent years there are some that are cultivated in a straight shape using pipes in the field. Nagamine is native to Yunnan, China, and is most commonly used as a edible yam. It is a so-called long yam that has a round cylindrical shape, a symmetric bee-shaped ginkgo moth ... ), And a bowl-shaped bowl with a diameter of about 10 cm (Kusaneimo ... there are black Kaga Maru and black Ise-an, and it is also called Yamato in Kansai). is there. In addition, Oiso is a tropical yam that is cultivated in small quantities in Kyushu, etc., and has a large variety of shapes as the name suggests.

  Such yam is mainly composed of starch, but it contains amylase (diastase), a starch-degrading enzyme, and a lot of glycoprotein mucin as a unique sticky ingredient. This mucin cooperates with other ingredients. Thus, it is presumed to exhibit an excellent moisturizing effect on the skin and its high durability.

  In the present invention, the yam component to be blended in the cosmetic may be collected from a stem or root cocoon. In collecting from stems, the stems are cut into appropriate lengths of several centimeters, or chopped directly or wrapped in a cloth or the like to obtain a juice, or an alcohol base or cosmetic base Soaked in an aqueous solution for a certain period (usually about one week) to obtain an extract extract. In collecting the juice, it is preferable to squeeze the cut stem after it is once immersed in the aqueous solution and swollen. On the other hand, when collecting from a cocoon, the cocoon cut into strips or the like is preferably immersed in an alcohol aqueous solution or a cosmetic base aqueous solution for a certain period (usually about one week) to obtain an extract. Such a yam component may be collected manually in a small amount, but may be mass-produced by mechanization. In addition, although the extract from straw is initially colorless, it is recommended to be used after this coloration since it will be stabilized from pale yellow to brown when left for about one week after extraction.

  As for the moisturizing effect when blended in cosmetics, it has been found that the yam component collected from the stem is stronger than the yam component collected from the straw. In particular, the yam component collected at the time when the stem began to turn from a blackish color to green (generally around June) has the strongest stickiness and is excellent in efficacy. However, the yam component collected from root cocoons is suitable for people with weak skin because it has little irritation to the skin. Therefore, by combining the yam component collected from the stem and the yam component collected from the root cocoon, and adjusting the properties such as moisturizing effect and irritation by the mixing ratio of both, the condition and taste of the user's skin It is possible to adapt to the difference.

  The cosmetics of the present invention include various types of lotions, such as emulsions, creams, gels, foams, etc., in addition to various lotions generally referred to as lotions. The amount of the yam component varies depending on the type of cosmetic and the application site of the skin, but in general, in the case of lotion, the range of about 0.1 to 2 g is preferably used as the raw material stem or pod. Therefore, the cosmetics used on the skin can be easily removed with a normal soap or facial cleanser.

  In addition, natural potatoes, long-necked potatoes, large potatoes, and the like, which are raw materials for the yam component, can be obtained at a relatively low price for edible use, and since the yam component can be easily collected as described above, the cosmetic of the present invention is inexpensive. Has the advantage that it can be mass-produced.

  In the cosmetic of the present invention, together with the yam component, if necessary, other plant components such as aloe, lemon, pearl barley, ginseng, polyhydric alcohols, sodium hyaluronate, sodium chondroitin sulfate, collagen, high Other moisturizing ingredients such as molecular polysaccharides, various vitamins, nutrient ingredients such as royal jelly, UV absorbers, preservatives, bactericides, antioxidants, colorants, fragrances, pH adjusters, etc. Good.
