Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cosmetic, particularly a cosmetic containing an extract of yeast.

[0002]

2. Description of the Related Art In order to prevent skin aging and maintain skin whitening, cosmetics containing components extracted from yeast have been proposed.

The components extracted from yeast have the effects of promoting the metabolism of the skin, suppressing the thickening of the stratum corneum and preventing the aging of the skin, and suppressing the production of melanin to keep the skin whitening. .

[0004]

However, a component extracted from yeast has an effect of preventing skin aging and keeping whitening of the skin. However, if the component alone is used as a cosmetic, this effect is Not fully exerted.

Therefore, an object of the present invention is to provide a cosmetic composition which prevents skin aging and sufficiently exerts the effect of maintaining whitening of the skin.

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a cosmetic containing an extract of yeast, which is at least one of gardenia, kujin or agets extracts. Provided is a cosmetic comprising one kind of thing.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Yeast used in the present invention is Saccharomyces (Sacharomyces) such as brewer's yeast and baker's yeast.
omyces) and others.

The yeast can be extracted by a physical, chemical or biochemical method, for example, yeast cells can be extracted by autolysis, hot water extraction, hydrolysis, enzymatic decomposition or the like.

Here, the content of the yeast extract is preferably in the range of 0.0001 to 20% by weight with respect to the entire components of the cosmetic.

When the content is less than 0.001% by weight, the effect of preventing skin aging and the effect of whitening the skin are not sufficiently exerted, and
Even if it exceeds 20% by weight, the effect commensurate with the addition of the content is not exhibited.

Gardenia jasmi
Nodes) is a madder plant and its fruit is used as a prescription drug for Kampo medicine for the purpose of antipyretic, anti-inflammatory, and hemostasis.

Kujin (Sophora flavesc)
ens) is a bean plant and its root is used for the purpose of diuresis, antipyretic and the like.

Ages (Rosa multifor)

Example 1 An experimental example of the cosmetic material according to the present invention is shown as Example 1.

Table 1 is a list of the components of the cosmetics used in the experiment.

[0040]

[Table 1]

As shown in Table 2, component A in Table 1 was not added in Experimental Example 1, 1% by weight of gardenia extract was added in Experimental Example 2, and in Experimental Example 3, , 1% by weight of the extract of Kujin, 2% by weight of the extract of Ages in Experimental Example 4, 1% by weight of the extract of Gardenia and 1% by weight of Extract of Kujin in Experimental Example 5. 1% by weight of the extract of the gardenia, 1% by weight of the extract of gardenia, 1% by weight of the extract of kujin, and 2% by weight of the extract of Agetsu. In Example 7, the extraction of gardenia 1 wt% Kujin extract 1 wt% Aget extract 4 wt%, in Experimental Example 8 gardenia extract 1 wt% Kujin extract 1 wt% Aget extract 5% by weight is added.

Then, the metabolic rate, rough skin improving effect and whitening effect are measured for each of these experimental examples.

The metabolic rate was measured by preparing a coating agent containing a fluorescent dye, dansyl chloride, in white petrolatum at 5% by weight, applying it on the skin of the forearm of 20 test subjects for 24 hours, and dansyl chloride on the stratum corneum. Osmotic bond,
Then, the test sample was applied to the same site twice a day (morning and evening), the fluorescence of dansyl chloride was examined every day, and the number of days until the fluorescence disappeared was defined as the metabolic rate.

The number of days shown in Table 2 is a weighted average of the measured values of 20 test subjects.

The measurement method of the rough skin improving effect is carried out by the subject (2
2 times a day (morning, evening) within the prescribed range of the lower leg of 0 people, 3
The test sample was applied for 0 days, and the water content in the stratum corneum was measured before and after the start of the test. From the measurement results, the first step:
Normal (20% by weight or more), Second stage: Light drying (15% by weight or more and less than 20% by weight), Third stage: Medium drying (10% by weight or more and less than 15% by weight), Fourth stage: Heavy drying It is classified as (less than 10% by weight), and the case where there is one or more improvement from the start to the end of the test is regarded as effective, and Table 2 shows the number of people judged to be effective.

The whitening effect was measured by applying the test sample to the faces of 20 test subjects twice a day in the morning and in the evening for 30 days, and the results were evaluated by a questionnaire of 20 test subjects.

The questionnaires answered by the subjects were good, good, normal, regarding the whitening effect, and the items such as light and dark spots on the face, dark and light freckles, and degree of sunburn.
Table 2 shows that the number of respondents who responded in five stages of dissatisfaction and dissatisfaction, and answered all the items as good or good was effective.

[0048]

[Table 2]

As shown in Table 2, the gardenia was found in all of the metabolic rate, rough skin improving effect, and whitening effect as compared with the case where the extract of gardenia, kujin, and aget was not included (Experimental Example 1). It can be seen that the effect is higher when the extract of Ginseng, Kujin and Ages is contained.

In particular, as shown in Experimental Examples 6 and 7, particularly when gardenia extract: kujin extract: ages extract are mixed in a ratio of 1: 1: 2-4. Has a remarkable effect.

[0051]

Example 2 The neutral cream according to the present invention was produced by homogenizing the raw materials shown in Table 3 below by a conventional method for producing cream.

[0052]

[Table 3]

The total amount of purified water is 100% by weight.

[0054]

Example 3 The emulsions according to the present invention were produced by emulsifying the raw materials shown in Table 4 below by a conventional method for producing emulsions.

[0055]

[Table 4]

The total amount of purified water is 100% by weight.

[0057]

Since the present invention is constituted as described above, it is possible to provide a cosmetic product which prevents skin aging and enhances the effect of maintaining whitening of the skin.

Further, in the present invention, a natural substance is mixed to prevent skin aging and enhance the whitening effect, so that a highly safe cosmetic composition can be provided.
