Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cosmetics that can be suitably used in basic cosmetics, make-up cosmetics, hair cosmetics, bath additives, and the like. More specifically, the present invention relates to a cosmetic that exhibits excellent cosmetic effects by incorporating an extract obtained from a fruit selected from the group consisting of purple violet, Japanese violet, violet violet, white violet, yellow violet, and velvet purple.

0002

[Prior Art and Problems to be Solved by the Invention] Murasakikibu, Omurasakibubu, Komurasaki, Horaimurasaki, Yabumurasaki, and Velveteen Murasaki are plants belonging to the Verbenales, Verbenaceae, and the genus Murasakibi. Very little research has been done on its use in the cosmetics field.

[0003] As a result of repeated research by the present inventors, we found that the extracts obtained from these fruits have high moisturizing power, excellent antioxidant effects, and ultraviolet absorbing properties. Cosmetics containing extracts obtained from the fruits of plants belonging to the genus Murasakibu, such as velvet purple and velvet purple, moisturize the skin, prevent spots and freckles, and further improve the skin by suppressing the production of lipid peroxides. The present inventors have discovered that the present invention has an excellent cosmetic effect in preventing skin troubles and maintaining a youthful skin condition, and has completed the present invention.

0004

[Means for Solving the Problems] That is, the present invention is characterized in that it contains an extract obtained from a fruit selected from the group consisting of Murasakikibu, Omurasakibu, Komurasaki, Horimurasaki, Yabumurasaki, and Velvet Purple.

Examples include nonionic surfactants such as polyoxyethylene hydrogenated castor oil, sucrose esters, and fatty acid amides.

Examples of the moisturizing agent include synthetic moisturizing agents such as glycerin, propylene glycol, 1,3-butylene glycol, and sodium pyrrolidone carboxylate; hyaluronic acid, collagen, elastin, placenta extract, royal jelly, microbial fermentation liquid, etc. Examples include natural moisturizers.

[0017] Examples of the pH adjuster include organic acids such as sodium citrate and citric acid, and salts thereof.

Examples of the thickener include carboxymethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, carboxyvinyl polymer,
Examples include polyvinyl alcohol and gum tragacanth.

Examples of the preservative include paraoxybenzoic acid esters such as methylparaben, ethylparaben, propylparaben, and butylparaben, ethanol,
Examples include dehydroacetic acid.

Examples of the antioxidant include vitamin E, butyloxytoluene (BHT), butyloxyanisole (BHA), and the like.

Examples of the pigment include red iron oxide, yellow iron oxide, black iron oxide, titanium oxide, nylon powder, sericite, mica, and talc.

Examples of the cleaning agent include sodium hydrogen carbonate.

Examples of the excipient include sodium sulfate.

Examples of the emulsifier include soybean lecithin oil.

[0025] The amount of each of these cosmetic ingredients varies depending on the intended use of the cosmetic, and therefore cannot be determined unconditionally, and is preferably adjusted as appropriate depending on the intended use.

The form of the cosmetic of the present invention is arbitrary and is not limited, but since it has excellent properties such as moisturizing the skin and preventing stains and freckles, it may be, for example, cream, milky lotion, lotion, etc. Examples include basic cosmetics such as face wash and packs, makeup cosmetics such as lipstick and foundation, and toiletry products such as body wash and soap.

[0027] Furthermore, the cosmetics of the present invention act on the area around the hair roots and on the scalp, and are effective in preventing split ends and hair breakage, as well as protecting the scalp. I can give it to you.

[0028] Furthermore, when the extract and its dry powder are added to hot water, it is effective in retaining heat and improving the condition of the skin after bathing, so the cosmetic composition of the present invention can also be used as a bath additive. be able to. In this way, when the cosmetic of the present invention is used as a bath agent, the amount of extract added to the cosmetic is 0 in terms of the solid content of the extract per 100 parts of the cosmetic.
．． 01 to 1 part, preferably 0.05 to 0.5 part. When using the bath agent, it is preferable to adjust the amount of the bath agent to about 25 g per 200 liters of normal hot water.

Next, the cosmetic composition of the present invention will be explained in more detail based on Examples, but the present invention is not limited to these Examples.

Preparation example 1 (manufacture of purple extract)

Reference Examples 1 to 7 The following test (i) was conducted using the extracts obtained in Preparation Examples 1 to 6 as samples.

(i) Lipid peroxide production inhibitory effect 0.5M
Linoleic acid ethanol 1.0ml, 0.2M phosphate buffer (pH 7.0) 10ml and ethanol 9.
0 ml of each was accurately weighed and mixed thoroughly in an Erlenmeyer flask with a stopper. To this liquid was added 5.0 ml of an accurately weighed 5% aqueous solution of the above extract, and the mixture was thoroughly shaken. Accurately weigh 0.1 ml of this solution immediately after preparation and after leaving it in a constant temperature bath at 40°C for 7 days, add 4.7 ml of 75% ethanol and 3.
After adding 0.1 ml of 0% ammonium thiocyanate solution and thoroughly mixing, the absorbance at 500 nm was measured exactly 3 minutes later, and the peroxide value index was determined from the following formula.

[0038]

[Math 1]

(In the formula, T7 is the absorbance of the solution to which the extract was added after 7 days from the start of the test, and B7 is the absorbance of the solution to which water was added instead of the extract after 7 days from the start of the test. , T0 indicates the absorbance of the solution to which the extract was added immediately after the start of the test, and B0 indicates the absorbance of the solution to which water was added instead of the extract immediately after the start of the test.) Also, water was used instead of the extract. The blank was used for the same operation. These results are shown in Table 1.
