The cosmetic composition for moisturizing skin in which snow-shaped particles are formed, has a shea butter, which is contained in an excess amount in an oil-based part, forming the snow-shaped particles while being naturally precipitated during low-temperature aging in a gel-form cream formulation, and when the cosmetic composition is applied to the skin, the moisture in the formulation penetrates into the skin and forms an oil film on the skin, thereby preventing evaporation of skin moisture, thereby exerting an excellent moisturizing effect on the skin.

Description

TECHNICAL FIELD The present invention relates to a cosmetic composition for moisturizing cream which forms snowflake particles and a method for producing the same,

The present invention relates to a cosmetic composition for skin moisturizing which forms snowflake particles in cosmetic formulations and to a process for producing the same. More specifically, the present invention relates to a cosmetic composition containing an over- The skin moisturizing factor penetrates into the skin and forms a thin film on the skin. When the skin moisturizing factor is applied to the skin, the skin moisturizing effect can be exhibited by preventing evaporation of the skin moisture. And a method for producing the same.

Skin moisturization is the most basic function of skin protection, and all commercially available cosmetics and medical skin products are among the most basic functions and are one of the most important technologies in cosmetic technology.

The major indicators of skin aging are skin wrinkles and reduced skin elasticity, which are known to influence factors such as collagen content and immunity to the external environment, the most significant of which is skin moisture content .

Epidermal cells located outside the skin form a barrier to the skin to prevent loss of moisture in the skin to promote moisturization and protect the health of the skin by preventing external harmful substances from penetrating into the skin . The skin has a protective film to prevent moisture from evaporating in the skin, which preserves skin moisture. However, due to various factors such as ambient temperature and humidity, skin temperature, and stratum corneum, skin moisture is lost on the skin surface.

If the skin barrier function is deteriorated due to various factors as described above, moisture loss of the skin occurs excessively and the skin becomes dry, and in some cases, skin wrinkles may occur due to reduction of skin elasticity. In addition, in persons with atopic skin, symptoms of inflammation or itching may occur more frequently due to loss of moisture evaporation in the stratum corneum due to decreased skin barrier function.

[Experimental Example 1: degree of skin moisture replenishment of Example 1 and Comparative Example 1]

The degree of hydration of the skin was measured by UVI (Ultra Violet Image) with 'DermaVision DermaView-PRO' of 'OptoBioMed' in order to examine the degree of moisturizing cream of the moisturizing cream forming the snowflake particles of Example 1 in detail.

The measurement of UVI was performed by applying a UVI photograph before and after application of a moisturizing cream for forming snowflake particles of the present invention on the backs of subjects, and the degree of hydration of the skin was expressed in the form of a graph and compared and analyzed (FIG. Fig. 3 is a graph showing UVI photographs of changes in skin hydration before and after application of moisturizing cream for forming snowball particles. DH, N, and HD on the graph indicate low water, normal, and moisture respectively.

As a result of measuring the degree of hydration of the skin, the degree of skin hydration after application was more shifted toward N and HD than before the application of the moisturizing cream for forming snowflake particles of the present invention. As a result, It was confirmed that the degree of hydration of the skin was improved by the moisturizing cream that formed the particles.

[Experimental Example 2: Evaluation of preference of moisturizing cream cosmetic composition for forming snowflake particles]

The moisturizing cream for forming snowflake particles of Example 1 and the conventional emulsifying type moisturizing cream of Comparative Example 1 were applied directly to skin for 15 men and women and the preference was selected for the three items of moisturizing, Respectively. The results are shown in Table 4 below.

Preference survey result The moisturizing cream of Example 1 The moisturizing cream of Comparative Example 1 Moisturizing 11 people 4 people burnish 10 people 5 people vitality 13 people 2 people

As a result of the preference test, the moisturizing cream for forming snowflake particles of Example 1 showed higher preference than the conventional emulsion-type moisturizing cream of Comparative Example 1 in all three areas. As a result, it was found that when the moisturizing cream for forming snowflake particles of Example 1 is used, the moisturizing feeling of the skin, the persistence of moisturizing of the skin, and the glossiness of the oil film when applied to the skin, Compared with the control group.
