Description

ANHYDROUS POWDER TYPE COMSMETIC COMPOSITION [0002]

The present invention relates to an anhydrous powder form cosmetic composition.

Powder-containing cosmetics are applied to the skin to improve the skin tone, while blocking the pores, wrinkles, and skin troubles while reinforcing the texture of the skin. Such an emulsion containing a powder is prepared in various formulations. In the case of an emulsified formulation, there is a problem that an emulsifier for uniformly dispersing oil and water is used, and the persistency of the emulsion is deteriorated during prolonged application. The emulsifier has a problem of inducing skin irritation .

Further, in the case of a waterless formulation, when the content of the volatile oil is increased to improve the absorption capacity, the stability of the formulation is unstable and the formulation is separated.

Therefore, there is a demand for development of a powdery anhydrous formulations having excellent absorption force and stable formulations.

The present invention provides an anhydrous powder form cosmetic composition. Hereinafter, the anhydrous powder type cosmetic composition according to the present invention will be described in detail.

In the present invention, the content of each constituent of the composition is limited in the range in which the sum of the sum of the total constituents exceeds 100% by weight.

In the description of the compound names in this specification, unless otherwise specified, the interpretation is in accordance with the definition of INCI (Intenational Nomenclature Cosmetic Ingredient).

In the present invention, an anhydrous powder formulation means that the composition does not contain water. This means that no water is added in the preparation of the composition. Specifically, the cosmetic composition according to the present invention has a water content of 10% by weight or less based on the total weight of the composition.

1) Silicon Elastomer gel

In the present invention, the silicone elastomer gel refers to a gel in which the silicone elastomer is absorbed in silicone oil, and the amount of silicone elastomer and silicone oil to be mixed therewith is not particularly limited.

In one embodiment of the present invention, the content of the silicone elastomer powder is 3 to 20% by weight, preferably 3 to 10% by weight based on the total weight of the composition. If the content of the silicone elastomer powder is less than 3% by weight, the oil may be separated over time to cause problems in formulation stability. If the content of the silicone elastomer powder is more than 10% by weight, the composition may be unfused and powdered, Lt; / RTI > On the other hand, when the content of the silicone elastomer powder is in the range of 3 to 20% by weight, there is flowability of the formulation and adhesion force between the powders, and the formulation can be kept in a stable state without separation or cracking due to time.

3) Silicone resin powder

In the present invention, the silicone resin powder includes a vinyl dimethicone / methicillic sesquioxane crosspolymer.

In one embodiment of the present invention, the content of the silicone resin powder is 5 to 25% by weight, preferably 5 to 10% by weight based on the total weight of the composition. If the content of the silicone resin powder is less than 5% by weight, a problem may arise that dough can not be formed at the time of manufacture due to insufficient bonding force between powders. When the content exceeds 25% by weight, oil is separated from the formulation, Occurs.

4) silicone oil

The silicone elastomer powder and the silicone oil absorbed by the silicone resin powder are applied to the skin and volatilized after the silicone elastomer powder and the silicone elastomer powder are applied to the skin, Silicone resin powder can effectively absorb oil components such as sebum and sweat of skin.

In one embodiment of the present invention, the silicone oil is any one selected from the group consisting of cyclopentasiloxane, cyclohexasiloxane, dimethicone trisiloxane, and dimethicone, or a combination thereof.

In one embodiment of the present invention, the content of the silicone oil is 40 to 60% by weight based on the total weight of the composition. If the content of the silicone oil is less than 40% by weight, the oil-absorbing ability is insufficient and the binding force between the powders is insufficient. In this case, the dough can not be formed at the time of production, There is a problem with stability.

5) Silicon Gelling agent

In the present invention, the composition contains a silicone gelling agent, so that even when a high content of silicone oil is contained, the composition can be stabilized without separating the phase of the formulation, and a soft feeling can be imparted.

In one embodiment of the present invention, the silicone gelling agent is dimethicone / phage-10/15 crosspolymer cyclopentasiloxane.

In one embodiment of the present invention, the content of the silicone gelling agent is 2 to 5% by weight based on the total weight of the composition. If the content of the silicone gelling agent is less than 2% by weight, the oil-absorbing ability is insufficient and the binding force between the powders is insufficient, so that the dough can not be formed at the time of production. When the content is more than 5% by weight, Problems arise in formulation stability.

The powder reflects light to improve skin tone, while blocking pores, wrinkles, and skin troubles, while absorbing sebum to enhance makeup sustainability, and to enhance skin texture.

In one embodiment of the present invention, the content of the powder is 2 to 25% by weight based on the total weight of the composition. If the content of the powder is less than 2% by weight, the powder does not adhere to the skin and has an unfavorable sensation of feeling on the surface. If the content of the powder is more than 25% by weight, the powder can not be formed.

In one embodiment of the present invention, the cosmetic composition may be formulated containing a cosmetically or dermatologically acceptable medium or base. These compositions may be prepared according to conventional methods in the art.

In addition, the cosmetic composition according to the present invention may contain adjuvants conventionally used in the field of cosmetics or dermatology, such as any other ingredient commonly used in cosmetics.

[Test Example 1] Measurement of sebum absorption capacity

When the cosmetic composition according to the present invention is applied to the skin, the oil-absorbing powder such as silicone resin powder and silicone elastomer powder is applied in a state containing oil, so that the ability to absorb sebum is poor immediately after application. However, Since the fat is vaporized and released, the sebum absorption ability is restored. To confirm this, 5 g of each of the compositions of Examples 1 to 5 and Comparative Example 1 was dispensed into a beaker, and after lapse of 30 minutes at 50 캜, caprylic / capric triglyceride (InterMed Quot; Imex MCT 60/40 ") was wetted as follows, and the absorption ratio thereof was measured.

The weight of CAPRYLIC / CAPRIC TRIGLYCERIDE was measured on 5 g of each of the compositions of Examples 1 to 5 and Comparative Example 1, and the sample was slowly dropped. While the caprylic / capric triglyceride was absorbed into the sample, Repeat. If caprylic / capric triglyceride can not be absorbed, the absorbed amount of each sample is recorded, and the sebum absorption rate is calculated by the following equation (1).

[Formula 1]

(%) = Final absorbed amount of caprica oil / capric triglyceride in the sample (unit g) / initial weight of the sample (5 g) X 100 (%)

The measurement results of the sebum absorption rate for Examples 1 to 5 and Comparative Example 1 are shown in Table 2 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Sebum absorption rate (%) 21 19 15 14 15 (Can not be measured by separator)

As shown in Table 2, Examples 1 to 5 are excellent in sebum absorption rate, whereas Comparative Example 1 can confirm that the formulation can not be separated and the sebum absorption rate can not be measured.

[Test Example 2] Measurement of formulation stability

Each of the above Examples 1 to 5 and Comparative Example 1 was placed in a tube container and placed in an inverted lid. The mixture was allowed to stand at a temperature of 55 캜 for 2 weeks or longer, and then discharged to observe the condition of the formulation.

The formulation was judged to be "separated" when the oil separated only according to the drop in viscosity or when the oil was separated on the skin side when applying the skin. When the problem was not observed, it was judged as "stable ".

Table 3 shows the measurement results of the separation of formulations in Examples 1 to 5 and Comparative Example 1.
