Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic having a high whitening effect.

[0002]

2. Description of the Related Art Dingji is called Cushion, and the scientific name is Eugenia Caryophyllata.
Alternatively, Syzygium aromaticu
m), the dried flower buds of this tree are called Doji, and English name is Globe. It is widely used as a spice. On the other hand, it is also used as a medicine,
As an aromatic stomachic drug, it has been applied to spleen stomach chills, vomiting, efferents, abdominal pain and other diseases. However, it has never been used as a cosmetic.

[0003]

The object of the present invention is to select a plant containing a component having a large skin whitening effect from plants which have been used for other purposes for many years and are confirmed to be safe for the human body. , To provide a cosmetic containing the ingredient.

[0004]

Means for Solving the Problems Among the plants which have been used for many years such as edible and have been confirmed to be safe, the present inventors have examined those which have utility value as cosmetics. As a result, they have found that Koji characters are extremely effective as a raw material for cosmetics or as a quasi drug, and completed the present invention. That is, the present invention is a whitening cosmetic containing a solvent extract of Toji.

The method of utilization is extraction with water or a hydrophilic organic solvent such as ethanol, methanol, acetone or a mixed solvent thereof. However, it is an extraction of cosmetic ingredients. Naturally, extraction with water or ethanol or a mixed solvent thereof is preferable. In some cases, a polyhydric alcohol such as glycerin, 1,3 butylene glycol, propylene glycol or the like or a mixed liquid of polyhydric alcohol and water can be used for extraction. It is also effective to freeze-dry and use it as a powder depending on the method of use.

[0006] This substance can be used as other cosmetic raw materials such as liquid oils such as squalane and jojoba oil, solid oils such as beeswax and cetyl alcohol, various activators, moisturizers such as glycerin and 1,3 butylene glycol, and various drugs. It can be added to prepare cosmetics in various dosage forms. For example, a lotion, a cream, a milky lotion, a pack or the like may be used depending on the purpose.

EXAMPLES The practical use method will be specifically described below with reference to examples, but the present invention is not limited to these examples.

(Production Example 1) 30 g of methanol in 10 g of a letter
0 ml was added, a reflux condenser was attached, and the mixture was heated for 3 hours. This was filtered and freeze-dried.

(Manufacturing Example 2) 300 g of 50% methanol aqueous solution was added to 10 g of T-shaped letters, a reflux condenser was attached, and 3
Heated for hours. This was filtered and freeze-dried.

(Production Example 3) Purified water of 300 m per 10 g of T-shaped
1 was added and heated for 3 hours. This was filtered and freeze-dried.

(Example 1) Lotion (parts by weight) Extract of Production Example 1 1.0 Ethanol 80.0 Purified water 19.0

(Example 2) Cream (parts by weight) A Squalane 20.0 Jojoba oil 5.0 Beeswax 5.0 Cetostearyl alcohol 2.0 Glycerin monostearate 1.0 Sorbitan monostearate 2.0 Production example 3 Extract 1.0 B Purified water 55.9 Polyoxyethylene (20E.0) sorbitan monostearate 2.0 Polyoxyethylene (60E.0) hydrogenated castor oil 1.0 Glycerin 5.0 Paraoxybenzoic acid Methyl 0.1 A and B were weighed and heated to 70 ° C., A was gradually added to B while stirring, and then 30 while slowly stirring.
Cooled to ° C.

(Example 3) A lotion in which the extract of Production Example 1 of Example 1 was replaced with the extract of Production Example 2.

(Measurement of Tyrosinase Activity Inhibition Rate) (Test Method) Mackle Balun Buffer 0.9 ml, 1.6
6 mM, tyrosine solution 1.0 ml, sample (dry matter) was dissolved in ethanol, water was added, and ethanol was removed by an evaporator, and then 0.1 weight (dry matter) / volume%
1.0 ml of the sample solution prepared in 1. was placed in a screw vial and heated in a 37 ° C. constant temperature water bath for 5 minutes. 0.1 ml of tyrosinase solution (manufactured by Sigma, derived from mushroom, 914 units / ml) was added, and the mixture was kept warm in a constant temperature water bath at 37 ° C., and after 10 minutes, the absorbance was measured at 475 nm. As a control, pure water was added instead of the sample solution and the same measurement was performed. (Calculation formula) Tyrosinase activity inhibition rate (%) = {B- (AP)} /
B × 100 However, A: Absorbance of sample specimen B: Absorbance of control P: Absorbance due to coloring of sample specimen (3-fold dilution) The results are shown in Table 1.

[Table 1]

Usage test Five women were divided into left and right faces, one of which was applied with the cosmetic composition of the example and the other of which was applied with the cosmetic composition of the comparative example, and was used once or more every day. , I surveyed. In addition, the comparative example is obtained by replacing the extract of the character of Example in the production example with water. (Comparative Examples 1 and 2) In addition, 10 people were divided into 2 groups, and the following Table 2 was used.
The experiment was performed using the sample.

[Table 2] The criteria are as follows, and the results of the questionnaire are summarized in Table 3. Example is very good 3 Example is considerably good 2 Example is slightly good 1 No difference 0 Comparative example is good −1 Comparative example is good −2 Comparative example is very good − Three
