Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar-like solid cosmetic for lips which has a remarkably improved blood circulation promoting effect and excellent stability.

2. Description of the Related Art The color of a lip looks more beautiful as the color is brighter red, but it has been found that the color of the lip becomes a beautiful color with higher saturation as blood circulation is promoted. Also, with age, the color of the lips becomes dull and less colorful, but is thought to be improved by promoting blood circulation.

As a method of improving such blood circulation, a method of external use of vitamin E or the like is generally used. Also, in crude drugs,
Extracts such as Rokujo and Korean carrot are known as blood circulation promoters. In particular, Rokujo has long been awarded in traditional Chinese medicine as a health tonic, and contains calcium phosphate, calcium carbonate, and oncolia as its components. It is effective.

Problems to be Solved by the Invention As described above, Lokujo tincture, which promotes blood circulation of the lips and produces a bright red color, is not suitable for use in a stick-shaped solid cosmetic such as lip balm or lip stick from the viewpoint of stability. The amount was limited, the expected effect was weak, and it was not yet satisfactory.

In view of such circumstances, the present inventors have conducted intensive studies to obtain a solid cosmetic having a truly excellent lip blood circulation promoting effect, and as a result, by adding a freeze-dried powder of Lokujo tincture, The present inventors have found that colorful lips can be obtained by an excellent blood circulation promoting effect, and have completed the present invention.

Means for Solving the Problems That is, the gist of the present invention is to blend a freeze-dried powder of Lorca tincture into a bar-shaped solid cosmetic.

 Hereinafter, the present invention will be described in detail.

The tincture tincture used in the present invention is obtained by extracting deer mushrooms with ethanol or a mixture of ethanol and water. A freeze-dried powder is obtained by vacuum freeze-drying and pulverizing this tincture tincture.

The stick-shaped solid cosmetic contains a cosmetic powder, an oil agent and a wax as main components.

Rokujo tincture is a volatile component, and if it is mixed in an amount sufficient to obtain a satisfactory effect, the base will thin over time,
The problem of cracking arises. Thus, the present inventors have found that the incorporation of a lyophilized powder of the above-mentioned components has solved the problem with respect to stability and that a satisfactory effect has been obtained, and has completed the present invention.

The freeze-dried powder of tincture tincture may be added to the solid cosmetic bar in an amount of 0.01 to 20% by weight, preferably 0.1 to 20% by weight.
~ 5% by weight. If the amount is less than 0.01% by weight, a sufficient effect cannot be obtained, and if the amount is more than 20% by weight, an effect more than necessary may not be obtained.

The bar-shaped solid cosmetics of the present invention include, in addition to the above-mentioned essential components, other components usually used in bar-shaped solid cosmetics such as cosmetics and quasi-drugs, for example, oils such as squalane, liquid paraffin, paraffin wax, and microcrystalline. A wax component such as wax and ceresin, a wetting agent, an ultraviolet absorber, an antioxidant, a surfactant, a preservative, a fragrance, and the like can be appropriately compounded as necessary.

The dosage form according to the present invention is an oily stick-shaped solid cosmetic found in lip balms, lip sticks and the like, and can be appropriately used as a medical part or cosmetic.

EXAMPLES Next, the present invention will be described in more detail with reference to examples.
The present invention is not limited by this. The compounding amount is% by weight. In addition, the blood circulation promoting effect and the degree of improvement to colorful lips were judged from the use test by cumulative application.

Blood circulation promoting effect by cumulative application The test subjects were one group of 20 subjects, and one sample lip balm was applied to the lips after each meal, and one month later, the blood circulation promoting effect was examined.

The blood circulation promotion effect uses the blood flow meter LC-1 made by CANON,
Judged.

Judgment ◎: The ratio of the blood flow increase in the test subjects (effective rate) is 80% or more ○: The ratio of the blood flow increase in the test subjects (effective rate) is 60% or more 80 %: Less than 40% of test subjects show an increase in blood flow (effective rate) ×: less than 60% of test subjects show an increase in blood flow (effective rate) Is less than 40% Example 1 and Comparative Examples 1 and 2 will be described.

A lip balm was prepared according to the following composition, and the blood circulation promoting effect of the cumulative application was examined.

 The prescription and manufacturing method are as follows.

That is, 10 g of petrolatum and microcrystalline wax
6.0 g and 10 g of paraffin were mixed, a fragrance was added, the claims and the drug were added, and a required amount of castor oil was added to a total amount of 100 g, and the mixture was heated and melted, molded and adjusted.

Example 1 As is clear from Comparative Examples 1 and 2, the bar-shaped solid cosmetic of the present invention is a cosmetic excellent in blood circulation promoting effect.

Next, cumulative application was performed in the same manner as described above, and the degree of improvement in lip vividness was examined. The degree of improvement was determined using a color difference meter CR-200 manufactured by MINOLTA.

Judgment ◎: The ratio (effective rate) where the saturation increases among the examinees
In the case of 80% or more ○: The ratio of the increase in the saturation among the examinees (effective rate)
In the case of 60% or more and less than 80% △: The rate of increase in saturation (effective rate) among the examinees
In the case of 40% or more and less than 60% ×: The ratio of the saturation increase (effective rate) among the examinees
If less than 40% As is clear from Example 1 and Comparative Examples 1 and 2, the bar-shaped solid cosmetic of the present invention is a cosmetic excellent in improving the color of the lips.

Examples will be described below. All quantities are by weight.
