Description

Cosmetic composition for oil cake {Cosmetic composition for oil cake}

The present invention relates to a cosmetic composition for oil cakes, and more particularly, to a cosmetic composition for oil cakes, which has excellent high temperature fluidity, less bleeding, and good makeup persistence and usability.

The oil cake is largely composed of an oil part and a powder part, and is usually prepared by dispersing the powder part in an oil part, heating it to provide usability, and then molding the plate and solidifying the plate. The oil cake formulated in this way has a good skin adhesiveness, a good coverage for skin defects, and a cosmetic film having excellent water repellency compared to powder cosmetics. However, in order to secure the high temperature fluidity required during manufacturing, the oil cake must maintain the content of the oil portion of 40 parts by weight or more.Because of the high oil content, the lubrication phenomenon occurs during makeup, and the makeup film is formed by sebum secreted from the face. It has the disadvantage of easily distracting.

In order to remedy this disadvantage, US Patent No. 5,645,903 discloses an oil in water emulsion type solid cosmetic composition, US Patent No. 5,362,482 discloses a Water in Oil emulsion type solid cosmetic composition, and Patent No. 5,266,321 discloses a method for improving bleeding or lifting while maintaining a high oil content using a silicone gel. However, these compositions should be lowered to 30 parts by weight or less in order to ensure high temperature fluidity during molding. Therefore, there is a disadvantage in that it does not exhibit sufficient cosmetic effects such as color impartment and defect concealment by the powder part.

Accordingly, the technical problem to be achieved by the present invention is to provide a cosmetic composition for oil cake having a good makeup effect, less bleeding and very good makeup persistence and usability by solving the above problems by containing powder of sufficient high temperature fluidity and sufficient content. have.

In order to achieve the above object, the present invention is 45 to 60 parts by weight of powder, 40 to 55 parts by weight of oil and sorbitan monostearate, sorbitan sesquioleate and a mixture selected from the group consisting of 0.5 to 0.5 5 parts by weight, wherein the powder contains 0.5 to 5 parts by weight of dimethicone / vinyl dimethicone crosspolymer, and the oil provides 5 to 40 parts by weight of a volatile silicone oil. .

In the cosmetic composition according to the present invention, as the volatile silicone oil, it is preferable to use volatile octamethylcyclotetrasiloxane or decamethylcyclopentasiloxane, alone or in combination thereof.

Hereinafter, the present invention will be described in detail.

The cosmetic composition for oil cake of the present invention contains 40 to 55 parts by weight of oil, of which 5 to 50 parts by weight is volatile silicone oil. Since the oil content is in a range similar to that of a general oil cake, sufficient fluidity is imparted during molding, and since volatile silicone oil is volatilized during makeup, there is little bleeding after makeup and makeup sustainability is good. If the content of the volatile silicone oil is less than 5 parts by weight, the content of the volatile oil is too small, there is no effect such as lubrication improvement, if the content exceeds 40 parts by weight there is a problem in pulling the skin. As the oil, a paste oil, a liquid oil, a solid oil (wax) and the like may be used. Typically, hydrocarbon-based, higher fatty acids, higher fatty acid esters, higher alcohols, silicone oils, vegetable oils, and the like are used. In addition, a cyclic silicone type is used as the volatile silicone oil. In particular, volatile octamethylcyclotetrasiloxane or decamethylcyclopentasiloxane may be used alone or in combination thereof.

Since the volatile silicone oil contained in the cosmetic composition for oil cake of the present invention has a high temperature fluidity inferior to general hydrocarbon-based and ester-based oils, an appropriate surfactant was used to formulate it. In other words, the surfactants differ greatly in high temperature fluidity and pigment dispersibility according to their type, and sorbitan monostearate and sorbitan sesquioleate are polyoxyethylene methyl polysiloxane, polysorbate 60, polysorbate 20, and the like. Unlike the surfactant, since it is excellent in high temperature fluidity and pigment dispersibility, by adding 0.5 to 5 parts by weight of the cosmetic composition according to the present invention, sufficient high temperature fluidity and pigment dispersibility can be imparted.

In addition, the cosmetic composition for oil cake according to the present invention contains 45 to 60 parts by weight of powder to exhibit a sufficient cosmetic effect. Powders include sieving pigments such as talc, mica, kaolin and calcium carbonate, white pigments such as titanium oxide and zinc oxide, colored pigments such as iron sulfate, iron oxide, black iron oxide and ultramarine, mica titanium and iron oxide treated mica titanium. Raw materials such as pearlescent pigment, polymethyl methacrylate powder, nylon powder, cellulose, starch, silk, silica, etc. for the purpose of soft feeling and sebum control can be used. However, since the volatile silicone contained in the oil is rapidly volatilized from the skin during makeup, there is a problem in that the content of the oil portion decreases and the spreadability and the feeling of use decrease, so that 0.5 to 5 parts by weight of dimethicone / vinyl dimethicone crosspolymer is added to the powder. I solved the problem. That is, the dimethicone / vinyl dimethicone crosspolymer is excellent in elasticity, thereby reducing friction with the skin and giving a soft feeling when added to the powder.

Hereinafter, the present invention will be described in detail with reference to Examples. However, embodiments according to the present invention can be modified in many different forms, the scope of the present invention should not be construed as limited to the embodiments described below. Embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art.

Example 1

According to the composition shown in Table 1, the powder portion was pulverized twice in a pulverizer and added to the oil portion heated to 75 ~ 80 ℃. Subsequently, the mixture was stirred for 2 minutes at 1200 rpm using a disper mixer, heated to 75-80 ° C., degassed, and molded into a dish to prepare an oil cake.

Hereinafter, the oil cakes prepared according to Example 1 and Comparative Examples 1 to 3 were subjected to Example 1 and Comparative Examples 1 to 3 on both sides of the face of 20 women, and then the product was evaluated according to the following evaluation criteria. Table 2 shows the results obtained by averaging the surface condition, usability, makeup sustainability, glossiness, and coverage.

<Evaluation Criteria>

Very bad: 1

Poor: 2

Normal: 3

Very good: 5

Item Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Surface condition of the product 4.0 4.1 1.5 3.8 Feeling 3.7 3.5 3.3 2.5 Makeup persistence 3.8 2.4 3.9 3.7 Bundle 3.9 2.2 3.4 3.6 Coverage 3.8 2.8 3.7 3.6

As shown in Table 2, Example 1 containing the volatile silicone oil, the surfactant, and the powder according to the present invention can be seen that the surface condition, usability, makeup persistence, shine and coverage of the product are all good.

On the other hand, Comparative Example 1 does not contain a volatile silicone oil, so there is a lot of shine and cosmetic persistence, Comparative Example 2 and Comparative Example 3 does not contain a surfactant or powder according to the present invention, respectively, the high temperature fluidity is lowered, the appearance of the product This is poor or not comfortable to use.

As described above, the cosmetic composition for oil cake according to the present invention is not only excellent in high temperature fluidity, but also volatile silicone oil is volatilized after make-up, less bleeding, and make-up durability and feeling is very good.
