The present invention relates to an oil-in-water (silicone) foundation cosmetic composition and a method for preparing the same, more specifically, using 0.05 to 10.00% by weight of silicone acrylate in the oil phase, 0.05 to 10.00% by weight of the water-soluble acrylate copolymer in the water phase In addition, by controlling the ratio of internal and external phases and dispersing it in oil as a dispersion medium by using triethoxycaprylylsilane coating pigment, a stable foundation formulation was prepared by the phase-phase emulsification method to give a fresh and light usability and lasting effect. The present invention relates to a silicone foundation cosmetic composition and a preparation method thereof.

Foundation compositions are makeup compositions for human skin. Foundation compositions are commonly used to mask skin defects such as redness and spots, as well as giving beautiful colors to the skin, especially the face. Foundation is a cosmetic that is used on the entire face, and it is an important factor to feel and maintain.

Foundations generally include W / S, W / O, O / W and oil dispersed foundations. W / S (water in silicone) foundation is a foundation of continuous silicone with excellent resistance to sweat and sebum, but there is a limit in terms of stability of the formulation to exhibit a fresh and light feeling in use. W / O (water in oil) foundation has a slightly lower persistence on sebum than W / S foundation and has a feeling of oily oil rather than a light feeling of silicone. O / W (oil in water) foundation is limited to express a fresh and light feeling of oil by the oil in the inner phase. In addition, there is a disadvantage in that stains occur due to the lack of persistence for sweat and sebum. Finally, the oil-dispersible foundation is a foundation characterized by a high content of extender pigments, a high coverage and powdery feeling, and a high content of oil, which is characterized by long-lasting sweat.

Accordingly, the present inventors have studied to solve the above problems, and as a result, the continuous phase is water using a certain amount of silicone oil, and it contains a silicone acrylate or a water-soluble acrylate copolymer, thereby maintaining a light and fresh feeling while The present invention has been found to be able to produce a silicone foam foundation cosmetic composition having excellent durability.

Accordingly, it is an object of the present invention to provide an underwater silicone foundation cosmetic composition prepared by containing a certain amount of silicone oil so that the continuous phase becomes water.

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

The foundation of the present invention is a foundation containing a predetermined amount or more of silicone oil and a continuous phase of water, unlike a foundation of a general oil-in-water emulsion type. In the present invention, the silicone acrylate is used together with the silicone oil in the oil phase or the water-soluble acrylate copolymer is phase-emulsified to emulsify the foundation to impart a lasting effect to the foundation. In addition, by controlling the ratio of the oil content of the inner phase and the water content of the aqueous phase showed an excellent sustaining effect.

In the present invention, the silicone acrylate and the solid triethoxycaprylylsilane-coated powder pigment are uniformly dispersed in a silicone oil as a dispersion medium to prepare an oil phase, and the continuous phase containing a water-soluble thickener and a water-soluble acrylate copolymer. Water parts (aqueous phase) can be added to obtain a foundation of the silicone formulation in water.

First, the oil phase components collected in the aqueous phase of the present invention will be described.

As the silicone oil used in the present invention, it is preferable to use dimethicone, cyclomethicone and alkyl trimethicone oil, but is not limited thereto. Volatile cyclomethicone used as silicone oil in the present invention is better in water resistance and oil resistance than general oils and is suitable for the present invention due to the light and silky feel of silicone.

The content of the silicone oil in the cosmetic composition according to the present invention is 12.00 to 40.00% by weight, preferably 15.00 to 20.00% by weight. If the content of silicone oil is less than 12.00% by weight, the durability is poor and there is a dry feeling, and if it exceeds 40.00% by weight, the feeling becomes oily.

Silicone acrylate used in the present invention is a raw material that provides the persistence and soft feeling of silicone by the acrylate polymer is composed of a dendrimer structure of a plurality of trimethylsiloxy groups acrylate backbone. Silicone acrylate used in the present invention includes cyclopentasiloxane / acrylate / polytrimethylsiloxy methacrylate (Cyclopentasiloxane (and) Acrylates / Polytrimethylsiloxymethacrylates copolymer), the silicone acrylate in the cosmetic composition according to the present invention The content of is 0.05 to 10.00% by weight, preferably 1.00 to 5.00% by weight. If the content of the silicone acrylate is less than 0.05% by weight, the persistence is inferior, and if it exceeds 10.00% by weight, it is sticky and inferior.

In addition, the cosmetic composition according to the present invention may further contain a solid powder pigment coated with triethoxycaprylylsilane in the oil phase portion for excellent dispersibility and durability.

In the present invention, as a powder pigment, a solid powder pigment coated with triethoxycaprylylsilane may be used as titanium oxide / aluminum hydroxide / triethoxycaprylylsilane (TITANIUM OXIDE / ALUMINUM HYDROXIDE / TRIETHOXYCAPRYLYLSILANE). The solid powder pigment may be dispersed in an oil which is a dispersion medium to facilitate the dispersion through a phase emulsification method to prepare a foundation formulation having high emulsion stability.

The content of the solid powder pigment is 5.0 to 30.0 wt%, preferably 10.0 to 20.0 wt%, based on the total weight of the composition.

Hereinafter, the water phase component for collecting the oil phase component will be described.

Water-soluble acrylate copolymers (Acrylates Copolymer) used in the present invention is excellent in water resistance and oil resistance by forming a crosslinked film when the volatile components are volatilized in the form of being emulsified in water. The nature of the properties does not affect the hardness and viscosity of the formulated foundation, so the spreadability and stickiness does not deteriorate. The content of the water-soluble acrylate copolymer (Acrylates Copolymer) in the cosmetic composition according to the present invention is 0.05 to 10.00% by weight, preferably 1.00 to 5.00% by weight. When the content of the water-soluble acrylate copolymer is less than 0.05% by weight, the persistence is lowered, and when the content of the water-soluble acrylate copolymer is greater than 10.00% by weight, a slid phenomenon due to the excess film appears.

In addition, the cosmetic composition according to the present invention can be easily selected and used by those skilled in the art for water-soluble thickeners such as xanthan gum, cellulose, bentonite and magnesium aluminum silicate to form the formulation in the water phase.

The cosmetic composition according to the present invention is characterized in that the weight ratio of the oil (oil phase) of the inner phase and the aqueous phase of the outer phase is 16.5: 70.7 to 40.6: 49.40, preferably 25.0: 60.0 to 35.0: 50.00.

In addition, in the present invention, dicaprylylcarbonate, C12-15 alkylethylhexanoate, butylene glycol / dicaprylyl dimethicone, phenyl trimethicone, etc. may be further used as an oil for controlling the content ratio of the internal phase oil. have. The content of the oil is preferably 3.0 to 6.0% by weight, and the oil component increases due to the addition thereof, thereby increasing the water resistance to water. When the content of the oil is less than 3.00% by weight, there is no water resistance to water, and when it exceeds 6.00% by weight, the usability becomes oily.

[Test Example 1]

In order to measure the persistence of the foundations prepared in Examples 1 to 5 and Comparative Examples 1 to 2, the same amount of the contents was evenly spread on the artificial skin, and after 30 minutes, the persistence of water and oil was compared. The results are shown in FIGS. 1 to 3. Table 4 below is the numerical data obtained by observing FIGS. 1 to 3, and FIG. 4 is a graph showing the persistence data of Table 4.

Persistence against water and oil Trial sample water oil Example 1 One - Example 2 3 - Example 3 7 9 Example 4 7 9 Example 5 5 7 Comparative Example 1 0.5 - Comparative Example 2 9 5

As can be seen from Figures 1 to 4, Examples 2 to 5 of the underwater silicone foundation of the present invention was confirmed that the excellent durability compared to Comparative Examples 1-2. In the above results, the sustainability of Comparative Example 2 is higher than that of Example, but when considering the results of the feeling performed in Test Example 2 below, it can be seen that the formulation of Example was superior to Comparative Example.

[Test Example 2]

In order to determine the feeling of feeling of Examples 1 to 5 and Comparative Examples 1 to 2, the respective feelings (smoothness, lightness, freshness, oiliness, etc.) were evaluated through panel tests. The results are shown in Table 5 and FIG. 5. Each item is given a score of 1 to 9 points, and the higher the score, the stronger the property. For example, when the spreadability is 9 points, it means the best spreading, so it is good in terms of feeling, and in the case of 9 points of oil feeling, the feeling of oil is the strongest, so the feeling is not good.

As can be seen from the above results, the S / W emulsion formulation foundation containing the acrylate polymer had a high index of freshness and lightness and moisture, and a low oiliness and stickiness.

In Example 3, silicone acrylate is a silicone polymer having acrylate as a backborn to form a thin film, thereby exhibiting durability and light compatibility. The water-soluble acrylate copolymer of Example 4 has excellent film-forming ability to form a coating film and does not impair spreadability or lightness even when the properties are used for emulsification in a liquid emulsion state. Thus, by containing the silicone acrylate and the water-soluble acrylate copolymer, the persistence of sweat and sebum was relatively better when Examples 3 and 4 were considered in consideration of the durability and the feeling of use than Examples 1 and 2. A foundation of fresh and light usability was able to be produced.

In addition, in Example 5, by using an oil other than silicone, water resistance was increased, and the usability was also kept fresh and light.

As described above, the cosmetic composition according to the present invention is capable of producing S / W foundation cosmetic composition containing silicone acrylate in the dispersion medium or water-soluble acrylate copolymer in continuous water, It maintains light and fresh feeling and has a long lasting effect to remove stains caused by sweat and sebum.
