Description

Water-in-oil cosmetic composition containing porous polyhedron powder

The present specification relates to a water-in-oil cosmetic composition comprising a porous polyhedron powder.

In the human body, the skin acts as a protective film to protect the living body from the external environment. It prevents the loss of biological components such as water or electrolytes and prevents harmful substances from entering the body. . Such skin is largely divided into epidermal layer, dermal layer and subcutaneous fat layer. The epidermal layer is composed of keratinocytes and melanocytes. Since the outermost keratinocyte layers of skin are in direct contact with the external environment, they require strong resistance to physical, chemical, or permeation of substances, and prevent the loss of moisture from the body to the outside. At the same time, it should maintain flexibility by retaining adequate moisture on its own.

In general, the moisture content of the skin is about 70% in the dermal layer, but decreases toward the epidermal layer, which is about 10 to 30% in the keratinocyte layer. The water supplied from the dermal layer is mainly moved up the stratum corneum by passive diffusion and finally discharged to the outside. This is called Trans Epidermal Water Loss (TEWL), and it is known that it is the sebaceous component and the epidermal lipid which are the lipid membrane components of the keratinocyte layer to maintain the appropriate level of transdermal moisture loss. In addition, the keratinocyte layer is known to play an important role in moisturizing the skin due to the presence of a substance having a hydrophilic water retention ability called a natural moisturizing factor (NMF). When the moisture of the normal keratinocyte layer is maintained about 10 to 30%, the skin is smooth and soft, and the body protects normally. However, when the moisture content of the keratinocyte layer is less than 10%, the skin becomes rough and the body loses its protective function, resulting in aging. For example, in the case of dry skin, the aggregation force of keratinocytes is weakened, and a scale phenomenon in which keratinocytes are peeled off like a piece of scale from the surface of the skin appears. Thus, the dryness of the skin is a moisture content of the keratinocyte layer. This is because it is less than normal skin. In addition, even healthy skin may suffer from a lack of moisture due to harsh external environment, ie, wind, cold weather, sunlight, face wash, shaving, and so on, may cause a bad skin condition. Therefore, it is very important to properly maintain the moisture content of the keratinocyte layer of the skin, and at the same time to provide the keratinocyte layer of the skin with an adequate level of moisturizing to antioxidant effect.

On the other hand, in the gloss product that gives skin luster, 100% oil (oil phase) product may be used, but even if it is made lightly, the oil-specific film makes the skin hard. Therefore, the conventional cosmetic composition for supplying proper moisture to the skin is made in the form of emulsifying a certain amount of water phase in the oil phase using an emulsifier (W / O emulsion). At this time, the existing W / O emulsions stably disperse the water in the oil using an emulsifier. The use of emulsifiers is accompanied by a heavy feeling of use and sensitive to light, thereby oxidizing greatly affects the stability of the contents. Thus, there is a need for a water-in-oil cosmetic composition that stably disperses water in oil without the use of emulsifiers.

In addition, since the adhesion to the skin is excellent, there is a property that does not erase well when applied to lipstick or gloss products.

In addition, the porous polyhedron powder is amphiphilic because it has both lipophilic and hydrophilic properties.

Generally, when the dispersed particles are rigid (fine particles (hundreds of nm or more)) and have a spherical shape (silica bead, nylon powder, or acrylic resin powder), the blowing is severe. However, the porous polyhedron powder of the present invention has a polyhedral shape particle shape, and because the particle size is 8 μm or less, the oil absorption power is large and the skin adhesion is good.

Example 1 and Comparative Examples 1 to 2 are shown in Table 1.

Comparative Example 1 A 100% oil composition Comparative Example 2 B 85% oil, 10% moisture, 5% spherical porus silica powder Example 1 C 85% by weight of oil, 10% by weight of water, 5% by weight of polyhedral porus silica powder

As a result of evaluating the feeling of use after preparing the gloss including the compositions of Comparative Examples 1 to 2 and Example 1, Comparative Example 2 and Example 1 showed a refreshing feeling due to moisture, while A gave a conventional rough coating. The difference in the usability of the comparative example 2 and the example 1 is understood to be largely determined by the silica powder.

Moreover, the observation result was shown in FIG. 2 by the optical microscope. Comparative Example 2 (B) is a form in which the water is forcibly loosened in the oil phase somewhat unstable as shown in the photograph, and there is a possibility that it may be aggregated over time, Example 1 (C) was not observed directly under the microscope, It was confirmed that the net structure was closely dispersed. Therefore, it was confirmed that Example 1 is more excellent in moisture stability than Comparative Example 2.
