Description

TECHNICAL FIELD The present invention relates to a composition for cleansing both skin peeling and sodium polyacrylate,

The present invention relates to a skin cleansing composition containing sodium polyacrylate and more particularly to a composition for cleansing both skin and non-aqueous or gel-like water (sodium polyacrylate) Aqueous) composition for exfoliation and cleansing.

Skin stimuli are diverse, such as natural irritations such as strong winds, heat waves, cold, ultraviolet rays, and artificial environmental stimuli such as air pollutants and acid rain. These stimuli may be further divided into physical and chemical stimuli. The outermost layer of the skin has various defenses to effectively protect against various stimuli and contaminants in contact with the skin. A representative mechanism for effectively defending against these stimuli is defense against keratin. The keratin of the skin grows from the lowest layer of the epidermis, gradually rises to the outermost surface of the epidermis, and then naturally separates from the epidermis layer after a certain period of time. This is called keratinization.

In modern society, hormone abnormality due to excessive stress and sudden changes in the external environment may result in abnormal keratinization of the stratum corneum due to the effects of air pollutants and ultraviolet rays, which surpass the skin's normal defense mechanism, The stratum corneum is abnormally expressed by exiting.

Due to the abnormal expression of stratum corneum, the skin tone becomes unstable and the skin becomes rough and dull. Also, when making a hue, the makeup appears uneven due to the uneven stratum corneum, and so-called make-up seems to be said to be exciting.

To solve these problems, various exfoliating cosmetics have been developed. The cosmetic materials for removing exfoliation can be roughly divided into a cosmetic composition for removing the exfoliation and a cosmetic composition for removing the exfoliation according to the method of removing the exfoliation.

Commonly used scrubs are artificial scrubs, such as polyethylene, and natural scrubs, such as walnut shells, peach or apricot, which are seeded with fruit seeds. In the case of the above-mentioned scrub, it is advantageous to make various kinds of scrubs by adjusting the size and shape of the scrub during the manufacturing process. However, when the scrubs are in use during use, , It is possible to feel a foreign body feeling with a great deal of pain, and in the case of rubbing the eye during the removal process, there is a possibility of serious damage to the eyeball.

In general, a skin cleanser that uses a bubble has a basic skin cleansing function that removes wastes and dirt from the skin. In recent years, many products have been developed, including scrubs, AHA, and BHA, or proteases such as proteases, to manage skin's keratin to provide multifunctional functions. . However, in the case of using these scrubs, strong scrubs can cause skin irritation. In the case of chemical peeling, the immediate effect is lowered. However, since the product has a low pH value, the possibility of stimulation is also high. This is not true for the immediate effect, but for the long-term effect. In addition, there is a great demand for the change of formulations while being used, and thus the demand for unique products is increasing continuously in terms of efficacy and usability.

In Table 1 and 2, 1 is a component for exfoliating effect, 2 and 3 are powder-type detergent components used in a non-aqueous form, 4 is a cooling component, 5 is a thermal component, and 6 is a detergent Ingredients and 8 are purified water.

Examples 1 to 3, 8 and Comparative Examples 1 to 2 are non-aqueous wash compositions.

In the case of Examples 1 to 3 , sodium polyacrylate and sodium cocoyl isethionate (Examples 1 and 2) or sodium myristoyl gluculatamate (Example 3) were mixed through a food mixer. In addition, urea (Example 2) and magnesium sulfate (Example 3), each of which can provide a cooling sensation in accordance with the characteristics of the product and the product, and a magnesium sulfate capable of imparting a thermal sensation, were added. In case of Example 8 , the characteristics of the ultimate peeling were confirmed using only sodium polyacrylate.

In the case of Comparative Example 1 , sodium cocoyl isethionate and sodium myristoyl glucutamate, which are the detergent components of the powder formulation, were not mixed with sodium polyacrylate, and in the case of Comparative Example 2 , sodium Sodium cocoyl isethionate and sodium myristoyl gluculatamate (Comparative Example 1), which contain the polyacrylate in small amounts and the detergent ingredients of the powder formulations, were mixed via a food mixer.

Urea and magnesium sulfate, which are used for non-aqueous washing to give a cool rim steel and a thermal sensation, are endothermic and exothermic reactions when dissolved in water, respectively, and can be formulated to suit the nature of the product. It is important to avoid contact with water because they are components that react with water. Therefore, it is characterized in that it is used only in a non-aqueous system formulation, not in a water system.

Examples 4 to 7 and Comparative Examples 3 to 4 are gel-type cleanser compositions.

In the case of the gel-type cleanser, all of the components other than sodium polyacrylate were mixed and finally a sodium polyacrylate was blended to prepare a gel-type cleanser.

As the sodium polyacrylate is contained, the sodium polyacrylate particles become larger due to the function of water and exhibit gel-like properties. This is because of the characteristics of sodium polyacrylate, and a desired property can be obtained if the cleanser before blending is an aqueous formulation containing water in a liquid or viscous liquid phase. In order to confirm this, Examples were the combination of surfactants, Examples 4 and 6, and Examples 5 and 7, which are combinations of soap bases.

As described above, the use properties of the detergent composition for both exfoliation and the exfoliation prepared according to Examples and Comparative Examples were confirmed. The results are shown in Fig. 1 and Fig.

As a result, as shown in Figs. 1 and 2, in the case of Examples 1 to 3 and 8 applied to the composition of the non-aqueous wash, in the case of Example 1, And the gommage peeling was observed due to continuous massage while showing the usability with the bubbles. In the case of Example 2, the user can feel the cooling feeling at the moment of additionally mixing water while showing the usability same as in Example 1 In the case of Example 3, the feeling of warmth was felt when the water was further mixed while showing usability similar to that of Example 1. In Example 8, there was no bubbling cleansing component and no bubbles were formed. When mixed with water, (Gommage) peeling occurred when the gel was made and continued to be massaged. In addition, in Examples 4 and 5 applied to the composition of the gel cleanser, In the contents containing sodium laureth sulfate and cocamidopropyl betaine, which are functional surfactants, and in the contents containing potassium myristate and potassium laurate soap as in Examples 6 and 7, sodium polyacrylate The content of the gel was increased by the combination of the rate and the property of the gel, and the usability of the gel was the same as that of using the water in the non-aqueous wash. That is, the non- Aqueous cleanser, which is a mixture of water such as a wash formulation or a gel cleanser formulation formulated by mixing water, was able to develop a cleanser capable of gommage filling due to the addition of sodium polyacrylate, Acrylate was found to be unique in its formulation and skin keratin effect.

On the other hand, Comparative Example 1 was a non-aqueous wash formulation of sodium polyacrylate and had no phenomenon to be mentioned in the present invention except bubbling occurred when used together with water. In Comparative Example 2 When mixed with water, sodium polyacrylate was swollen and had a scrub effect which gives a feeling of massage, but there was no increase in the amount of the mixture, but the phenomenon of sticking down like Gommage could not be found. That is, they showed usability different from those in Examples 1 to 3 and 8. In Comparative Examples 3 to 4, experiments were conducted on the amount of sodium polyacrylate added to an aqueous cleanser, and in Comparative Example 3, the amount of sodium polyacrylate was small, so that the sodium polyacrylate particles were swollen and scuffed with swollen particles But the gommage peeling effect was not observed. In Comparative Example 4, not only the amount of sodium polyacrylate was increased but also the sodium polyacrylate which was not reacted with water in the Aqueous cleanser There was a difficulty in formulation such as remaining.
