In addition, although a preferred method or sample is described herein, similar or equivalent things are included in the scope of the present invention. The contents of all publications described herein by reference are incorporated into the present invention. The term about refers to 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, for reference quantities, levels, values, numbers, frequencies, percentages, dimensions, sizes, quantities, weights, or lengths. By amount, level, value, number, frequency, percentage, dimension, size, amount, weight or length, varying by 3, 2 or 1%.

Throughout this specification, the words including and including, unless included otherwise, in the context include the steps or components set forth, or groups of steps or components, but any other steps or components, or steps or components It should be understood that this group is not excluded.

The stick type clay pack cosmetic composition according to the present invention may contain a polyol, a thickener, a clay component, a powder dispersant and a residual amount of water (purified water).

The polyol used in the present invention may be a polyhydric alcohol such as glycerin, butylene glycol, propylene glycol, dipropylene glycol, polyethylene glycol, propanediol, and may contain 10 to 30% by weight based on the total weight of the cosmetic composition. . If the polyol is less than 10% by weight, the feeling of use is stiff and can be easily dried. If the polyol is more than 30% by weight, the sticky feeling peculiar to the polyol is felt and the drying time is delayed, making it unsuitable as a clay pack.

The thickener used in the present invention may be sodium laurate, sodium myristrate, sodium stearate, sucrose and the like, and may contain 5 to 15% by weight relative to the total weight of the cosmetic composition. If the thickener is less than 5% by weight, since the hardness suitable for the stick type is not formed, it may be severe in the formulation when used in the form of a stick, and may affect stability. In addition, when the thickener exceeds 15% by weight, it is not suitable because the hardness is not applied to the skin and may be irritating.

The powder dispersant used in the present invention may be quaternium-90 montmononite, quaternium-90 sepyrite, stearalkonium bentonite, and the like, and may contain 0.30 to 3.00 wt% based on the total weight of the cosmetic composition. . If the powder dispersant is less than 0.3% by weight, the powder will not be dispersed properly and the clay will sink during cooling. If the powder dispersant exceeds 3.00% by weight, the viscosity will be so high that the clay dispersion will not be uniform, which is not suitable.

Clay component used in the present invention may be kaolin, bentonite, lava clay (morocco lava clay), colloidal clay (Canada colloidal clay), illite, charcoal powder and the like. Moroccan lavas (ghassoul) means clay mined in some parts of the Atlas Mountains of Morocco. Canadian colloidal clay means colloidal green clay from western Canada composed of silicon, aluminum, iron, calcium, sodium, magnesium and potassium. The clay component may contain 10 to 50% by weight relative to the total weight of the cosmetic composition. If the clay content is less than 10% by weight, the clay pack does not have the original application of stiffness and is dry and does not feel the tightening effect. If the content is more than 50% by weight, the application is too stiff and stiff, irritating the skin and drying quickly. .

In addition, the present invention relates to a method for preparing a clay pack cosmetic composition of the stick type, which is prepared by the following method:

1) The powder dispersant is sufficiently dispersed in the polyol with an Agi mixer for 10 minutes or more (first step)

2) uniformly dissolve the phase and the thickener prepared in the first step in a purified water heated to 70 to 80 ℃, preferably 80 ℃ while stirring (second step)

3) The clay is uniformly dispersed while stirring with an azi mixer (third step)

4) Cool to 50-60 ° C., preferably 55 ° C. while stirring with an azimixer and fill into a stick container (fourth step). If the temperature of the fourth step exceeds 60 ° C., the clay may sink down while cooling in the vessel, and if it is below 50 ° C., hardness will begin to form and filling will be difficult.

The cosmetic composition according to the present invention may further include an emulsifier, a solubilizer, a stabilizer, an emollient, a fragrance, a preservative, a pH adjusting agent, and the like within the scope of not impairing the object of the present invention.

Hereinafter, the present invention will be described in more detail with reference to examples, but the scope of the present invention is not necessarily limited to these examples.

<Production of Examples and Comparative Examples>

Experimental Example 1 Hardness Test

The surface hardness of the cosmetic compositions of Examples 1 and Comparative Examples 1 to 4 was measured using a FUDOH RHEO METER device, and the results are shown in Table 2 below. Hardness measurement was performed after storage for one day at 25 ℃ after manufacture, using a 15mm diameter adapter was measured for a depth of 1cm at a rate of 5cm / min.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Hardness 1.15 1.05 0.49 1.09 1.03

As shown in Table 2 above, in the case of Example 1 of the present invention, it can be seen that a stick type formulation having an appropriate hardness is formed. Comparative Example 1 had a hardness lower than that of Example 1 and had a stick appearance, but became a firm formulation as jelly, and Comparative Example 2 was a non-stick type general clay pack formulation because the hardness was not properly formed. Comparative Example 3 was similar in hardness to Example 1, but the clays were not evenly dispersed but agglomerated, and Comparative Example 4 was insufficient in clay to form a general moisture stick formulation instead of a stick type clay pack.

Experimental Example 2 Usability Evaluation

After using the samples of Example 1 and Comparative Examples 1 to 4 on the face of 30 women in their 20s and 30s, the usability of application, sebum adsorption effect, cleansing power, and finish was evaluated according to the following evaluation criteria. It is shown in Table 3 below.

[Evaluation standard]

Very good-5, Excellent-4, Fair-3, Bad-2, Very bad-1

Item Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Application 4.7 2.2 2.9 2.7 1.6 Sebum adsorption effect 4.9 3.8 4.1 2.9 1.2 Cleaning power 4.3 4.0 3.7 3.3 3.3 Finish 4.2 2.5 3.5 3.0 3.6

As shown in Table 3, Example 1 was evaluated as excellent in all items, specifically, it can be confirmed that it has a characteristic of having an excellent sebum adsorption effect, rapid cleaning, and a refreshing finish without drying, while being easily spread. . In Comparative Example 1, sebum adsorption effect and detergency were evaluated as normal or higher, but the polyols were insufficient to spread well, and after drying, they had a low score in application and finish. In Comparative Example 2, three items other than the application property were evaluated as a normal score or more, but since the hardness was not formed, it was found that the user felt uncomfortable to apply by hand during the application process because it was too soft. In Comparative Example 3, the clay was not uniformly dispersed and was evaluated as below normal in the spreadability or sebum adsorption effect. In Comparative Example 4, the claypack had no function and was too hard to obtain a low score in the spreadability and sebum adsorption effect.

Experimental Example 3 Sebum Adsorption Effect

In order to compare the sebum adsorption effect of Example 1 and Comparative Examples 1 to 4, the change in sebum amount before and after single use was measured in 20 men and women with a large amount of sebum secretion. In the measurement method, the samples of Example 1 and Comparative Examples 1 to 4 were applied to the skin and completely dried, and then the change of sebum was measured using a skinvisiometer sebufix tape and an analysis program, and the results are shown in Table 4.

Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Before use 13.25 13.25 13.25 13.25 13.25 after use 7.49 8.52 9.72 11.94 13.94 Improvement 43.47% 35.70% 26.64% 9.88% -4.95%

As shown in Table 4, Example 1 exhibited an excellent sebum adsorption effect compared to Comparative Examples 1 to 4. In Comparative Example 3, since the clay was not uniformly dispersed, the sebum adsorption effect was not large. In Comparative Example 4, the sebum adsorption effect could not be expected because it did not contain clay. It is considered that the sebum adsorption effect of Example 1 is superior to Comparative Example 1 and Comparative Example 2 having the same clay content because the clay is completely attached to the skin with moderate hardness and application properties.

Experimental Example 4 Formulation Stability Evaluation

Formulation stability of Example 1 and Comparative Examples 1 to 4 prepared above were evaluated.

Evaluation criteria for long-term preservation stability of the cosmetics in units of 1 week, 1 month and 3 months in a thermostat and room temperature of 4 ℃, 45 ℃, 50 ℃ and 4 ℃ -45 ℃ cycle (Cycle) The results are shown in Table 6 below.

From Table 6, Example 1 according to the present invention was found to be excellent in long-term storage stability. In Comparative Example 2 and Comparative Example 3, because the components affecting the hardness and the dispersion of the clay is missing, high temperature stability was not good. Therefore, it can be seen that Example 1, in which the polyol, thickener, clay, and powder dispersant are properly formed, has no problem in long-term storage stability.
