Description

Solid emulsion cosmetic composition containing silicone resin powder

The present invention relates to a solid emulsion cosmetic composition containing a silicone resin powder, and more particularly, to disperse the silicone resin powder alone in an emulsion containing a large amount of volatile components that can be easily vaporized when applied to the skin, or hydroxyapatite Solid emulsion cosmetic composition that can be mixed with and dispersed to effectively absorb sebum secreted when applied to oily skin with a lot of sebum secretion, and improve makeup's sustainability. It is about.

In general, solid emulsion cosmetics are cosmetics in which the formulation is solid by increasing the content of wax in the formulation in which the necessary powders are dispersed after emulsifying the aqueous phase and the oil phase. In the solid emulsion cosmetics, the foundations are mixed with a binder such as oil. There is an emulsion-type foundation in which a pressed powder, which is a molded powder, and a pigment are properly dispersed and emulsified in an aqueous phase and an oil phase. Among them, the powder type foundation is easy to use and the skin is thin, so it has good air permeability.Therefore, it has a light and natural feeling. There is a shortcoming of this shortage, and the emulsion type foundation has a clear makeup effect as well as a certain lasting power compared to the powder type, but the makeup is easily distracted by sebum or sweat secreted from the skin. Therefore, in recent years, a lot of foundations that improve these disadvantages are commercially available, and has been continuously studied. However, despite these research efforts, oily skin owners are constantly demanding measures against sebum, and because of fine lines and wide pores, skin texture cannot be multiplied or deep bones such as around the nose There is also a phenomenon such as being lifted up without close contact.

The present inventors have repeatedly studied to solve the above problems, the silicone oil powder having a high oil absorption capacity alone in the emulsion containing a large amount of volatile components that can be easily vaporized when applied to the skin, or skin affinity Contrary to the conventional method of introducing sebum defense function to foundations by dispersing with mixed with good hydroxyapatite, it is a cosmetic that focuses on sebum defense function. -It absorbs sebum secretion by applying locally to T-zone area, and it can be used for topical areas where makeup is not adhered well because skin texture is not smooth and it can correct skin texture. It is easy to carry and provides a solid emulsion cosmetic which can aim to stabilize the formulation. That knows thereby completing the present invention.

Accordingly, an object of the present invention is to provide a solid emulsified cosmetic composition that can effectively absorb sebum and increase the persistence of makeup, and correct skin texture to increase the makeup effect.

In order to achieve the above object, the solid emulsified cosmetic composition according to the present invention is a powder capable of correcting skin texture while having a high oil absorption force and a high skin affinity, and the silicone resin powder of 1 to 30% by weight relative to the total weight of the composition. And hydroxyapatite in an amount of 0.5 to 5% by weight based on the total weight of the composition.

In addition, the solid emulsion cosmetic composition according to the present invention is characterized in that it contains 20 to 80% by weight of volatile components, such as purified water, alcohol, volatile silicone, etc., in order to maximize the function of the powder.

The above and other objects, features and advantages of the present invention will become apparent to those skilled in the art from the following detailed description.

Hereinafter, the present invention will be described in more detail.

The solid emulsified cosmetics of the present invention are considerably lighter by silicone and silicone resin powder when applied to the skin, and have strong sebum absorbing ability. Therefore, most women who use oily skin or have complex skin owners do not use the entire face. -When used exclusively for local areas such as T-zone and left and right bones, the function can be maximized.

In addition, the makeup base, which is a kind of a conventional solid emulsion cosmetic, contains some color pigments for skin color correction, but the cosmetics of the present invention are intended for use only for topical areas such as the nose or forehead. There is a characteristic.

Solid emulsion cosmetics of the present invention can effectively absorb sebum in order to improve makeup sustainability, and by controlling the sebum secreted by containing a powder that can complement the skin texture to improve the sustainability of makeup and skin texture I can express it smoothly.

In the present invention, in order to effectively absorb sebum, the organic or inorganic powder which has been widely used in recent years has been examined as silica, hemp cellulose powder, yeast polysaccharide powder and the like. Because of the disadvantages such as very rough, grievous and poor adhesion in terms of field or feeling, the present invention is to use a silicone resin powder that is excellent in oil absorption, light and good lubricity.

The silicone resin powder used in the present invention is an ultra-fine particle made of dimethyl silicone crosslinked elastomer (elastomer) and has a dimethylsiloxane skeleton so that it has no stickiness and imparts lubricity and smoothness to cosmetics. In addition, as can be seen in Table 1, it has an oil absorption capacity significantly larger than the conventional cosmetic powders.

Table 1

Oil absorption ability of cosmetic powder (g / 100g)

Therefore, the solid emulsion cosmetic composition of the present invention contains the silicone resin powder having the above-mentioned efficacy in an amount of 1 to 30% by weight based on the total weight of the composition.

However, in the solid emulsion cosmetic composition of the present invention, if the silicone resin powder is simply dispersed in the emulsion, the oil-absorbent powder itself absorbs the emulsion to form a formulation, even though the silicone resin powder has a large oil absorption capacity. Because it contains a lot of fluid in itself, the oil absorption capacity is reduced, and when applied to the skin in such a state that the phenomenon of no longer absorbing sebum secreted from the skin occurs.

Therefore, in the solid emulsion cosmetic composition of the present invention, in order to maximize the oil absorption function of the high oil absorption silicone resin powder dispersed in the emulsion, the emulsion contained in the silicone resin powder must be released, so that the volatile component that can be easily vaporized when applied to the skin Disperse the silicone resin powder in a large amount of emulsion.

The volatile component used in the solid emulsion cosmetic composition of the present invention is not particularly limited, but is used in an amount of 20 to 80% by weight based on the total weight of the composition, for example, at least one selected from purified water, alcohol, and volatile silicone. . On the other hand, the volatile silicone of the volatile component is cyclomethicone, octamethylcyclotetrasiloxane of tetramer structure or decamethylcyclopentasiloxane of pentamer structure, used in an amount of 10 to 30% by weight based on the total weight of the composition It is preferable.

In the present invention, when applying the cosmetics in which the silicone resin powder is dispersed in an emulsion containing a large amount of volatile components on the skin, within a short time, the volatile components in the emulsion are vaporized and released into the air, and eventually the oil absorption powder is left on the skin. Not only can it effectively absorb sebum secreted from the skin, but silicone resin powder is applied to the deep bones on the left and right sides of the nose and the unsmooth areas of the skin with the proper amount of some non-volatile emulsion and wax. It spreads smoothly by the lubricity and smoothness that it has, and it naturally penetrates wrinkles and bends that are not easily adhered to by ordinary cosmetic powders. Reduced adhesion and makeup It is effective to prevent the lifting phenomenon.

In addition, the solid emulsion cosmetic composition of the present invention further contains hydroxyapatite in an amount of 0.5 to 5% by weight relative to the total weight of the composition in order to increase the sebum absorption ability of the silicone resin powder to further increase the persistence of the makeup.

In addition, the solid emulsion cosmetic composition of the present invention is 0.1 to one or more selected from waxes such as ceresin, candelilla lead, carnauba lead, paraffin, beeswax and hardened oil in order to solidify the oil phase and stabilize the emulsion. It is contained in an amount of 6% by weight, and the oil-in-water type emulsifier and the oil of triglyceride- or ester-based oil of about 3 to 5 are mixed, heated and dissolved.

In addition, in order to assist sebum absorption function and improve usability, one or more powders such as polymethyl methacrylate, silica and nylon having excellent spreadability are dispersed in an oil component in an amount of 10 to 30% by weight.

The solid emulsion cosmetic composition of the present invention may have a conventional formulation, for example, may be formulated as a foundation, makeup bases, twin cakes and the like. The composition of each of these formulations may contain a variety of bases and additives necessary for the formulation of the formulation and are suitable, and the types and amounts of these components can be readily selected by those skilled in the art.

Hereinafter, the configuration and effects of the present invention will be described in more detail with reference to Examples.

[Manufacturing method]

1) The raw materials 1-3 were heated and dissolved to 75 degreeC, and the raw materials 4-7 were mixed gradually.

2) The raw materials 8 to 10 were mixed, added and dispersed in 1) above.

3) The raw material 11 was emulsified while mixing slowly with said 2).

4) The raw material 12 was sufficiently dispersed while slowly entering the above 3).

[Test Example 1] sebum oil absorption ability

When applying the cosmetics according to the present invention on the skin high oil absorption powders such as silicone resin powder is applied in a state containing the emulsion, sebum oil absorption ability is lost at that moment, but after only a few minutes after application of the volatile component vaporized and released Sebum absorption ability is revived. To confirm this, the cosmetics of Examples 1 and 2 and Comparative Examples 1 and 2 were respectively coated on a glass plate with a uniform thickness of 10 g each, and after 30 minutes, each sample was scraped and acetylate drolinol alcohol set as artificial sebum. The amount of absorbable artificial sebum was measured while wetting. The results are shown in Table 2 averaging three measurement results.

TABLE 2

Oil absorption measurement result

As can be seen from Table 2, the best oil absorption in Example 1 containing both silicone resin powder and hydroxyapatite was shown, and Example 2 does not contain hydroxyapatite, so it has a synergistic effect of sebum oil absorption. There was no oil absorption somewhat less than in Example 1 was recorded. On the other hand, Comparative Example 2 contains a high oil absorption powder, such as silicone resin powder, hydroxyapatite, but using non-volatile silicone instead of volatile silicone, because it is manufactured by reducing the amount of water and increasing the amount of oil, due to vaporization after application Since the amount of discharge is insufficient, the oil absorption power of the high oil absorption powder cannot be restored, and the oil absorption amount is smaller than that in Example 1.

[Test Example 2] Measurement of sebum oil absorption ability by measuring the brightness and saturation for each makeup duration

If a lot of sebum is secreted over time after makeup, the pigments absorb the sebum and the brightness and saturation are lowered, respectively, if effective sebum defense does not occur. Since it can be effectively defended, apply about 0.2g of regular makeup base and cosmetics of Examples and Comparative Examples to the forehead of women with oily skin and apply 0.3g of twin cakes on each forehead. The change in brightness and saturation with was measured using chroma meta (color difference analyzer, Minolta, USA). The measured values L ^* , a ^* , b ^* were shown in Table 3 after measuring three times.

The value of C ^* representing saturation was calculated according to Equation 1 according to Hunter's law.

[Equation 1]

TABLE 3

Table 4 summarizes the difference in brightness and saturation after the initial use and after 4 hours using the measurement results in Table 3.

TABLE 4

As can be seen in Table 4, when comparing the brightness and saturation after the first use and after 4 hours, the difference was smallest when the Example 1 product and the twin cake were used.

[Test Example 3] sebum oil absorption ability and skin texture complementary function

For 50 women in their 20s and 30s, the general makeup base and the cosmetics of Examples and Comparative Examples were used daily as twin cakes, and the sebum absorption capacity and skin texture complementary function were evaluated according to the following evaluation criteria. The results are shown in Table 5.

* Evaluation standard

Excellent: 5, little excellent: 4

Normal is: 3, a little lack: 2, lack: 1

TABLE 5

As can be seen from Table 5, the skin texture correction function is greatly improved by the silicone resin powder, which has excellent skin affinity and elasticity, and the silicone resin powder mainly acts to effectively absorb sebum and increase the persistence of makeup, and it is hydroxy. When the apatite is used together (Example 1), it can be seen that the function is increased. In addition, even when both raw materials such as silicone resin powder and hydroxyapatite are used, when the volatile component is insufficient in the formulation (Comparative Example 2), the ability to absorb sebum secreted from the skin is reduced due to the high absorption of the emulsion in the formulation. It can be seen.

As can be seen from the above description, the solid emulsion cosmetic composition of the present invention is dispersed in a silicone resin powder having excellent skin affinity and excellent sebum absorption ability in an emulsion containing a large amount of volatile components such as water and volatile silicone, or hydroxyapatite And volatile components contained in silicone resin powder are vaporized and released when applied to the skin by dispersing it, and it effectively absorbs sebum secreted by the revitalized oil absorption ability and improves the makeup's sustainability. When applied to uneven areas, it evens out the texture of the skin and has the effect of preventing the appearance of smooth skin and lifting of makeup. In addition, the solid emulsion cosmetic composition of the present invention is easy to carry and can stabilize the formulation.
