Description

[0001] HIGH MOISTURIZING AND MILD COSMETIC COMPOSITION FOR WASHING [0002]

TECHNICAL FIELD The present invention relates to a cosmetic composition for cleaning and a method for producing the same, and more particularly to a cosmetic composition for cleansing which has excellent foamability, cleansing power and moisturizing power and is hypoallergenic.

A general cleaning cosmetic composition is largely divided into a paste type, a gel type, and a mousse type cleaning cosmetic composition. Each of the cleansing cosmetic compositions has advantages and disadvantages. Since the formulation of the mousse-type cleansing cosmetic material is liquid, the fatty acid is difficult to be used for the formulation, and the foamability and cleaning power are increased by using only the anionic surfactant. Also, anionic surfactants based on sulfates used as anionic surfactants tend to be used in the cosmetics market in recent years because of their high irritancy.

In addition, the cosmetic composition of the mousse type has a problem in that it is difficult to use an oil component in the formulation itself, and tends to feel skin pulling or drying after cleansing or washing. For this reason, it is necessary to maintain appropriate moisturization on the skin by using moisturizing cosmetics such as body lotion and body oil as essential after cleansing or washing.

Furthermore, it is difficult to add a fatty acid to the formulation itself due to the use of a mousse-type cleansing cosmetic, which causes a problem that the foaming power and cleansing power are lower than that of a paste-type cleansing cosmetic.

 Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a cosmetic composition for cleaning having excellent moisture retention, foaming power and detergency without using a sulfate anionic surfactant.

1 to 6 of water components are mixed and sufficiently dissolved at room temperature using an agitator (AGI MIXER), followed by heating to 70 to 80 ° C. Then, the oily components 7 to 9 are separately heated to 70 ° C to 80 ° C. The dissolved aqueous phase components and the oil phase components are homogenized by a homomixer (HOMO MIXER, PRIMI, TK HOMO MIX ER 2.5 MODEL) at a low speed of 500 rpm to 1000 rpm. After stirring, 10 dissolved in purified water is added. The homomixer is then heated to 1000 rpm to 1500 rpm, cooled to 65 캜, and then added to 11 to 14, followed by progressing the homomixer at 1000 rpm to 1500 rpm. Then, the oil components 15 to 16 are added, and the emulsification process proceeds while the homomixer is operated at 1000 rpm to 1500 rpm. Finally, the additives 17 to 18 were put in, and the homomixer was run at 1000 rpm to 1500 rpm, followed by defoaming and filtration. The photographs of the cosmetic compositions of Examples 1 to 4 and Comparative Examples 1 and 2 thus prepared are shown in Fig.

Experimental Example  1: skin Moisture power  effect

In order to examine the effect of improving the skin moisturizing effect on the cleaning cosmetic composition of the present invention, the following experiment was conducted. Twenty twenty to forty persons without skin disease were divided into two groups each consisting of 20 persons per one group, and the detergents of Examples 2 to 4 and Comparative Example 1 prepared in Preparation Example 1 were administered twice daily for 1 month The skin conductivity was measured using a corneometer (CM820 courage Khazaka electronoc GmbH, Germany) under the constant humidity condition (24 ° C, 40% humidity) after cleaning the face and the front part. , 2 weeks, and 4 weeks after the administration, and the rate of increase of the skin conductivity was evaluated. The results are shown in Table 2 below.

As shown in the results of Table 2, the rate of increase of the skin conductivity was much higher than that of Comparative Example 1 in the case of Example 2, Example 3 and Example 4 of the cleaning cosmetic composition of the present invention. In general, the skin conductivity is proportional to the amount of skin moisture, and as a result, it can be confirmed from the above results that the cosmetic material of the present invention maintains a higher moisture content than the other cosmetic materials. Therefore, the cosmetic of the present invention is excellent in skin moisturizing effect. However, it can be seen that the bubbling force is not good in the case of the embodiment 2 and the embodiment 4 in the above embodiment, as compared with the embodiment 3. [ In general, one of the functions of the oil component is to have a vesicle force. It was found that this vesicle force had the effect of suppressing the foaming power in the cleaning agent. In the case of Example 2, no fatty acid was added. In Example 4, it can be confirmed that the content of the oil component was excessively added. In Example 1, a preferable example of the composition of the cosmetic composition which increases the moisturizing power while maintaining the bubble power can be referred to as Example 3.

Experimental Example  2: Skin safety experiment

In order to investigate the objective stimulation of the primary stimulus appearing on the skin, the experiment was conducted on 15 subjects with healthy skin under 20 to 50 years old. The volatile substances were volatilized for 1 hour after dropping 20 제품 of the product in the coagulation chamber, and then the patches were attached to the subjects, and after 24 hours, the pellets were removed and the readings were performed 30 minutes later. The samples used in the experiment were the Example 3, Comparative Example 1, and Comparative Example 2 prepared in Preparation Example 1, respectively.

As shown in the results of Table 3, Example 3 of the cleaning cosmetic composition of the present invention showed that the sodium laureth sulfate most commonly used among sulfate anionic surfactants was used in Example 1 and Comparative Example 2 , The safety test results were much better than those of the conventional method. As can be seen from the above experiment, the cosmetic of the present invention is considered to be suitable as a cosmetic for skin cleansing with low irritation.

Experimental Example  3: Cosmetics Bubble power  Experiment

In order to test the foaming power of the cosmetic of the present invention, the foaming powers of the formulations of Examples 1 to 4 and Comparative Examples 1 and 2 of Production Example 1 were compared with each other using the same container of the mousse type. We measured the length, height, and height of the bubbles by pumping each formulation once in the same container. The size of the bubbles was measured. After one minute, the bubbles were measured by changing the size of the bubbles.

As shown in the results of Table 4, the foaming powers of Examples 1, 3 and Comparative Example 2 of the cosmetic composition for cleaning of the present invention were the most excellent. Compared with Comparative Example 1, there was no significant difference in the foaming power when the container was discharged, but there was a large difference in the degree of bubble retention. As shown in Example 4, it was found that when the oil component was added in an excess amount, the bubble power was not good and the degree of oil retention was adversely affected.

Experimental Example  4: Cosmetics  Washing power experiment

Based on the results of Experimental Example 3, in order to examine the washing power of Example 1, Example 3, and Comparative Example 1 and Comparative Example 2, which have the best bubble power, The experiment was conducted on 15 subjects. After the lipstick and mascara were painted on the back of the hand for 4 cm, the amount of lipstick and mascara remaining on the back of the hand was measured after pumping the products of Example 1, Example 3 and Comparative Example 1 and Comparative Example 2 for 20 seconds. And the average value is shown in Table 5.
