Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning agent, and more specifically, to a cleaning agent that prevents the skin from feeling tight or scratchy due to cleaning, and is effective in preventing skin roughness. Regarding.

[Conventional technology] Cleaning agents are used to remove various types of dirt, etc., and increasing their cleaning power tends to cause skin roughness, so the development of medicinal agents that can sufficiently remove dirt and prevent skin roughness is long awaited. However, no medicinal agent having such effects has been found to date.

BACKGROUND ART Conventionally, various raw materials extracted from natural products, such as proteins, polysaccharides, extracts, natural polymers, etc., have been incorporated into cleaning products because of their distinctive effects. However, the effects were still insufficient and did not meet expectations.

[Problems to be Solved by the Invention] In view of the current situation, the present inventors have earnestly determined that there is no way to prevent the skin from feeling tight or scratchy due to washing, and to improve the effect of preventing skin roughness. As a result of research, the present invention was completed by discovering that this object can be achieved by incorporating a Nymphaeaceae plant or an extract thereof.

[Means for Solving the Problems] That is, the present invention provides a cleaning agent characterized by containing one or more of Nymphaeae plants or extracts thereof.

Hereinafter, the configuration of the present invention will be explained in detail. The plants of the Nymphaeaceae family that can be used in the present invention include Kouhone (Senkotsu), Nymphaeus japonicum, Lotus, Junsai, and the like. For example, Kouhone is used as a component of Chinese herbal preparations and crude drug preparations as a bruise medicine and a feminine medicine, but most of them are used as internal medicines, and there are no examples of it being added to cleaning products. Nymphaeaceae plants may be blended into the cleaning agent as a powder, or as an extract extracted with an appropriate solvent.

In the extraction method, the whole plant or rhizome of the scutellariae is heated under reflux in a suitable solvent such as water, a lower alcohol such as methanol or ethanol, or a water-containing lower alcohol, and then filtered. Generally, this extract is concentrated and used. The extract obtained by this method is
After the solvent is distilled off, it can be further dissolved in a solvent such as 1,3-butylene gelicol, or the obtained liquid can be appropriately concentrated and used in the present invention as a concentrate.

Alternatively, the extract obtained by extracting the rhizomes of Aspergillus orientalis with the above-mentioned suitable extraction solvent, or the extract obtained by extracting the rhizomes of Aspergillus orientalis with hot water, may be subjected to adsorption chromatography such as silica gel chromatography. It is also possible to use an extract obtained by fractionation.

In the present invention, the blending amount of Nymphaeaceae plants such as Nymphaeaceae is 0.001 to 10% by dry weight in the amount of cleaning fee.
, preferably from 0.05 to 5% by weight, more preferably from 0.01 to 1% by weight. If it is less than 0.001% by weight, no significant effect can be expected even if it is blended. 10%
Exceeding this is unfavorable in terms of the product manufacturing process. In addition, the amount of dry residue of the extract is o, oooi~ in the total amount of cleaning agent.
ix amount%, preferably 0.005 to 0.5% by weight, more preferably 0.01 to 0.1% by weight. 0.
If the amount is less than 0.001% by weight, the effect of the present invention cannot be fully exhibited even if it is blended.

In addition to the above-mentioned essential ingredients, the cleaning agent of the present invention may optionally include various ingredients commonly used in cosmetics, pharmaceuticals, etc., such as aqueous ingredients, powder ingredients, oils, and surface active ingredients, to the extent that the effects of the present invention are not impaired. Agents, humectants, thickeners, preservatives, antioxidants, fragrances, coloring materials, ultraviolet absorbers, drugs, etc. can be added. Further, the formulation of the cleaning agent of the present invention is arbitrary, and may be of any type, such as a solubilized type such as a lotion, an emulsified type such as a milky lotion or a cream, an ointment, a powder dispersion type, or a solid type.

Further, the use of the cleaning agent of the present invention is also arbitrary.

[Example] Next, the present invention will be roughly explained in detail using test examples and examples. Test Example 1.2 is a general test method for cleaning agents. Note that the present invention is not limited to this. The blending amount is in weight%.

Test example 1. Irritation (sensory evaluation) Evaluation was conducted by immersion test using 20 guinea pigs using the 1% aqueous solution (350c) of the liquid cleaning composition of Example 1. That is, a 1-minute immersion-drying operation is performed once a day for 3 days, and the degree of skin roughness is visually judged 24 hours after the final immersion using the following criteria.

0: Almost no skin roughness △: Partial exfoliation change in the stratum corneum surface layer of the skin ×: Dry exfoliation change in more than 30% of the skin Table 1 As shown in Table 1, Nymphaea plant extract residue was added. All showed significant effects compared to the control.

Test example 2. Practical Use Test A skin roughness prevention test after washing the face was conducted on a human body panel using the cleansing foam formulated in Example 2, in which the extract of a plant belonging to the Nymphaeaceae family was changed to 0% by weight and 2% by weight. That is, a replica of the skin surface of a healthy female person (face) is taken using a replica method using myristic resin and observed under a microscope (17x magnification).

Based on the criteria shown in Table 2, 40 people (skin roughness panel) were judged to have a skin roughness rating of 1.2 based on the condition of skin marks and peeling of the stratum corneum. The other 20 subjects washed their faces twice a day for one week using a cleansing foam that did not contain any extract of the same name. 24 hours after the end of the use test, a replica was taken again and the condition of the skin was observed and evaluated according to the criteria in Table 2.

(Margin below) Table-2 The results are shown in Table-3.

(The following is a blank space) Table 3 From the results, it was found that the facial areas treated with the cleansing agent containing the extract of Lamium chinensis were found to have a remarkable effect on preventing rough skin compared to the facial areas treated with other cleansing agents.
