Description

  The present invention relates to a moisturizing plant extract and a cosmetic, a bath preparation and a detergent composition containing the extract, which moisturizes the skin and hair and provides a healthy and healthy skin or hair. The present invention provides a composition useful for maintenance and regeneration. That is, dryness, rough skin, cracks, redheads, dandruff, kayumi, inflammatory diseases, prevention, reduction or improvement of skin, and dryness, dryness, split ends, cut hair, gloss, etc. The present invention relates to an effective moisturizing plant extract and a cosmetic, a bath preparation and a detergent composition containing the extract.

  Human skin and hair are moderately moisturized when healthy and usually do not require special care, but various environmental factors (e.g. temperature change, humidity change, light, water and water) Etc.), contact with detergents, etc., or aging often causes changes and troubles. That is, the skin and hair with a reduced moisturizing function are dried and hard, and the gloss and elasticity are lost, resulting in a crisp state. In recent years, such dry skin has been pointed out to be associated with atopic dermatitis, which is rapidly increasing, and may cause various skin troubles. In addition, troubles such as loss of luster, split ends and cut hairs occur even in the hair. Further progress is considered to cause serious conditions such as spots, wrinkles and hair loss.

  Conventionally, in order to prevent the skin and hair from drying, a herbal extract has been used alone or as a mixture of each extract in an external preparation such as cosmetics. For example, herbal extract with hydroquinone glycoside and whitening action: mulberry (peony), aloe, peony, oxon, hamamelis, salamander, honeysuckle, firewood, keihi, saishin, moray, maggot, sanshuyu, auren, morning glory, clara, Hosobaokera, Yomobi, Perilla, Sikon, Bodaige, Chamomile, Toki, Maronier, Senkyu, Tonin, Sage, Salvia, Ages, Pepper, Yakuchi, Ketsumeishi, Shukusha, Koboku, Rosemary, Gennoshouko, Kina, Birch, Clove, Clove Cosmetics containing Melissa, Nantenjitsu, Basil, Ginkgo biloba, Eleutherococcus (Patent Document 1), (a) one or more of mevalonic acid, mevalonic acid lactone, and (b) loquat, mono, aloe, kourainin , Loofah, peonies, oren, psyllium, button pi, genus shochu, cha, kujin, mandarin duck, sage, hammelis, birch, garlic, chimpi, chamomile, chilli, cypress, keihi, fennel, hops, gypsophila, sorghum, purple Skin cosmetic (Patent Document 2) containing a plant extract selected from one or more of the group consisting of Ginkgo, Bamboo, Sakuhakuhi, Semburi and Camellia (Patent Document 2), Asenyaku, Ginseng, Ogon, Oubak, Ouren, Gaiyou, Licorice, Pheasant, Moisturizing herbal ointment (patent document 3) containing herbal extract components of at least one herbaceous raw material selected from Keihi, safflower, Genjin, Giou, Soyo, Chai, Chinpi, carrot, mint and Yokuinin, Patent Document 3, Aubaku Ani, Mankeishi, aloe, explicit solution, Kikuka, rhubarb, frankincense, and skin protective additive, characterized in that an extract made from at least one of sieboldiana (Patent Document 4) have been proposed.

  However, conventional moisturizing components have not yet been satisfied in terms of touch, durability of moisturizing effect, and physicochemical stability.

  The present invention solves such a problem and contains a moisturizing plant extract that continues to have a moisturizing effect for a long time and the extract, and for skin, dryness, rough skin, cracks, red snapper, dandruff, Kayumi, for preventing, reducing or ameliorating inflammatory diseases, and for hair, cosmetics or bath preparations effective for drying, dryness, split ends, cut hair, gloss, etc., or rough skin, cracks, redheads, etc. The present invention provides an improved detergent composition that is less likely to cause skin troubles.

  In order to solve the above-mentioned problems, the present inventors searched various plant extracts and mixtures thereof, and as a result, an extract having the same composition as the Kampo formula called Gomotsugedokusan has a synergistically excellent moisturizing effect. And the present invention was completed. That is, the present invention is a moisturizing plant extract composed of an extract of a mixture of senkyu, juyaku, goldfish, mussel and dairy, and specifically, 0.5-12.5 parts by weight (the same applies hereinafter), juyaku Moisturizing plant extract consisting of an extract of a mixture of 0.2 to 5.0 parts, goldfish 0.2 to 5.0 parts, mussel 0.2 to 3.8 parts and diatom 0.1 to 2.5 parts More specifically, Senkyu 2.0 to 10.0 parts, Juyaku 0.8 to 4.0 parts, Kinginga 0.8 to 4.0 parts, Keikei 0.6 to 3.0 parts, and Diou 0.0. It is a moisturizing plant extract composed of an extract of 4 to 2.0 parts of a mixture, and more specifically, 3.5 to 7.5 parts of Senkyu, 1.4 to 3.0 parts of Juyaku, 1.4 to 1.4 3.0 parts, Kei-Gai 1.1-2.3 parts and da A moisturizing plant extract comprising 0.7 to 1.5 parts of a mixture extract, more specifically the moisturizing plant extract which is an extract of water or alcohols or a mixture thereof, and A cosmetic composition, a bath composition or a detergent composition containing the moisturizing plant extract.

  The moisturizing plant extract of the present invention continues to have a moisturizing effect for a long time, and the cosmetic and bath preparation containing the extract prevent dryness, rough skin, cracks, red snapper, dandruff, kayumi and the like on the skin. It is effective for reduction or improvement, and for hair, such as dryness, dryness, split ends, cut hair, and gloss. In addition, even in household detergents that have been concerned about skin troubles such as rough skin, cracks, and redheads, the moisturizing plant extract of the present invention eases such troubles so that it does not easily occur, and is a detergent that touches the skin. A composition can be provided.

The plants used in the present invention are shown below, and any of them can use leaves, stems, roots, flowers, seeds or whole plants. In addition, herbal medicines originating from the following plants may be used.
(1) Cnidium officinale Makino (Apiaceae)
(2) Houttuynia cordata Thunberg (Dokudamiaceae)
(3) Lonicera japonica Thunberg
(4) Keichi Schizonepeta tenuifolia Briquet (Lamiaceae)
(5) Rheum palmatum Linne, Rheum tanguticum Maximowicz, Rheum officinale Baillon, Rheum coreanum Nakai
However, the type of each herbal medicine is not limited to this, and variants, congeners, and other related species can also be used.

  Gomotsugedokusan is a combination of five kinds of senkyu, jujuyaku, goldfish, mussel and daiou, and is said to be effective against itching and eczema [Natural Product Pharmacy (Shuji Itokawa, Taichi Omoto, Masahiro Nagai, Riki Furuya, Published by Asakura Shoten, April 10, 1987 version)].

  Gomotsuge Doksan is used for itching and eczema with itching, and it is said to be effective for small rashes and eczema after measles, as well as epilepsy [Natural Drug Encyclopedia (published by Takuo Okuda, Yodogawa Shoten) March 3, 1986)].

  The active ingredient is extracted from the mixture of these plants using a suitable solvent. Examples of the solvent include water, alcohols (for example, lower alcohols such as methanol, absolute ethanol, and ethanol, or polyhydric alcohols such as 1,3-butylene glycol, propylene glycol, and dipropylene glycol). Any mixture can be used. Moreover, after extraction, the extract can be diluted or concentrated and dried as necessary.

  The extraction method is not particularly limited, and may be in the range up to the boiling point of the solvent at normal temperature or normal pressure, and a microwave extraction method or a supercritical extraction method may be used. After extraction, filtration or an ion exchange resin may be used for adsorption purification to form a solution, paste, gel, or powder. In many cases, it can be used as it is, but if necessary, further purification treatment such as deodorization and decolorization may be added as long as the effect is not affected. An activated carbon column or the like may be used, and usual means generally applied depending on the extracted substance may be arbitrarily selected.

  The herbal medicine used in the present invention provides a highly effective extract from a combination of five types extracted. Therefore, it is more effective than those extracted individually from each other, extracted by arbitrarily combining up to four kinds of plants, and mixed with each extract or extract. In addition, it is possible to obtain a result that the sustainability of the moisturizing effect is further improved by combining and extracting five kinds of plants, and the improvement effect on rough skin, dandruff, kayumi and inflammatory diseases is further improved. It seems to be sufficiently meaningful to use a product extracted by combining seed plants.

  The compounding amount of each herbal medicine used in the present invention is a collection of experienced Chinese medicine prescriptions (published by Nippon Shokudo Inc., 9th edition of 1993), and a guide to general Chinese medicine prescription (edited by the National Drug Association Chinese Medicine Special Committee, Ministry of Health and Welfare) The amount described in the 4th edition, 12th edition, April 30, 1992) is preferred. The blending ratio can be adjusted according to the purpose. For example, in the general Chinese medicine prescription, the weight ratio of Senku: Juyaku: Ginginka: Keigai: Daio is used as the prescription of Gomotsugedokusan 5: 2: Examples such as 2: 1.5: 1 are described. Accordingly, in the present invention, as usual blending amounts, 0.5-12.5 parts (parts by weight, the same shall apply hereinafter), juyaku 0.2-5.0 parts, goldfish 0.2-5.0 parts, 2 to 3.8 parts and 0.1 to 2.5 parts of daiou, more preferably 2.0 to 10.0 parts of Senkyu, 0.8 to 4.0 parts of Juyaku, 0.8 to 0.8 4.0 parts, 0.6 to 3.0 parts of mussel and 0.4 to 2.0 parts of diaoh, and the most preferable blending amounts are 3.5 to 7.5 parts of senkyu and 1.4 to 3. 0 parts, 1.4 to 3.0 parts of goldfish, 1.1 to 2.3 parts of mussel and 0.7 to 1.5 parts of dioio.
