Description

Foundation cosmetic composition having two layer

The present invention relates to a two-layer foundation cosmetic composition and a method for producing the same, and in particular, a specific gravity between a water layer consisting of water phase components containing water and butylene glycol, and a powder layer consisting of powder components including titanium dioxide, kaolin and iron oxide. The present invention relates to a two-layer foundation cosmetic composition and a method of manufacturing the same, which provide visual distinction by forming a layer divided into two layers in appearance, and at the same time, give a user a fresh and comfortable feeling such as a lotion on use.

As a foundation, the most important thing is to finish your face cleanly (covering skin, correcting textures, blemishes, freckles, etc.). In other words, powder, twin cakes, etc., which are commonly spoken, belong to the foundation. Table 1 shows the types of foundations currently commercialized (units are in weight percent, but only based on major ingredients, and as a result of analysis of commercialized products, the composition of 100% was not correctly indicated and is a reference for the following).

As shown in Table 1, the foundation is composed of three phases: powder, water phase (water), oil phase (oil), and powders include powder, pressed powder, twin cake, cake, and the like. It is adjusted according to the amount of oil used with the powder and gives a difference in the application power (coverage) to the skin. In addition, there are liquid type and oil painting type, and the foundation generally used is cream type foundation. The reason these foundations are used a lot is because the feeling is light and easy to spread. In particular, due to the characteristics of cosmetics, users have a large individual difference, and accordingly, products diversified according to color, flavor, and other useful bioactive substances and their functionalities (moisture, moisture, covering, etc.) It is manufactured and sold by the present situation.

In general, oil-in-water type emulsion foundation has excellent water resistance compared to oil-in-water type products because of its external appearance, but has a problem that the makeup film is lifted and agglomerated due to sweat, which has to be fixed at any time, and contact with external contact or clothing Due to the makeup is easily buried there is a problem such as making the clothes dirty or leaving makeup marks on the contact when changing clothes. In addition, it has a heavy and stiff feeling of use, and because the makeup film is thick, the skin breathability is inferior, thereby preventing skin breathing and making the skin stuffy. Therefore, in order to improve the sustainability in the conventional water-in-oil emulsion foundation, ester-based oils such as isopropyl myristate, triglycerine, and sorbitan fatty acid esters having excellent skin affinity and good adhesion, and liquid lanolin, lanolin, acetylated lanolin, etc. Many of the lanolin-based oils were relatively viscous.

However, in the case of using ester oil and lanolin oil, the sustainability is somewhat improved as compared to the case of using hydrocarbon oil, but the improvement is not so great, the skin safety is low, and the viscosity is relatively high. There are drawbacks to stickiness and heavy usability. Meanwhile, in order to further improve the water resistance of the water-in-oil type emulsion foundation, dimethiconol, which is a high viscosity silicone gum, was used together with the above oils, but they also improved the water resistance due to the film formation but the degree of improvement was not so great. , If used in excess, stickiness is severe, there is a problem such as skin pulling or skin tightness when forming a film.

In addition, the conventional two-layer foundation of the water-in-oil type (Water-in-Oil type) is usually made in water phase, so makeup is easily stained by sebum or sweat, or has a disadvantage of poor sustainability.

In particular, the composition of the foundation is commonly used to conceal beautiful color expression and skin defects on the face. In other words, when applying foundation on the skin, it should be applied softly and lightly, it has good skin adhesion and make-up effect, there should be no shine after time elapse, and the stability to skin should be maintained. However, conventionally known emulsified, powdered, and dispersed foundations use silicone oils, hydrocarbon oils, ester oils, and emulsifiers to give a feeling of greasy or heavy feeling when used, especially in summer makeup. The disadvantage is that you feel stuffy.

The present invention has been devised to solve the problems of the prior art as described above, and the conventional general formulation commercialized with a water layer consisting of water phase components including water and butylene glycol and a powder component comprising titanium dioxide, kaolin and iron oxide. By using the difference in specific gravity between powder layers, it is possible to form a layer divided into two layers in appearance to give visual differentiation and to give the user a fresh and pleasant feeling like a lotion in use, especially during summer makeup. It is to provide a two-layer foundation cosmetic composition and its manufacturing method that can reduce the tightness given.

As described above, the two-layer foundation cosmetic composition for achieving the object of the present invention is 5 to 15% by weight of powder, selected from the group consisting of a mixture of two or more of titanium dioxide, kaolin or iron oxide, 5 to 15% by weight of butylene glycol It comprises water as% and balance.

As the powder, kaolin may be preferably used.

The cosmetic composition may further include ethanol in an amount of 0.5 to 10% by weight based on the total weight of the composition.

The cosmetic composition may further include aluminum chlorohydrate in an amount of 0.01 to 5% by weight based on the total weight of the composition.

In addition, the method for producing a two-layer foundation cosmetic composition according to the present invention, (1) 5 to 15% by weight powder selected from the group consisting of titanium dioxide, kaolin, iron oxide or a mixture of two or more thereof butylene glycol 5 to 15 A dispersion step of mixing and dispersing together with the weight%; And (2) a mixing step of mixing the dispersion obtained in the dispersing step of (1) with water as a residual amount.

After the mixing step (2), 0.5 to 10% by weight of ethanol, 0.01 to 5% by weight of aluminum chlorohydrate or a mixture of two or more thereof are further mixed with the cosmetic composition obtained above, based on the total weight of the cosmetic. A second mixing step may be further included.

According to the configuration as described above, it is divided into two layers in appearance by using the specific gravity difference between the water layer composed of the water phase components including water and butylene glycol and the powder layer composed of powder components including titanium dioxide, kaolin and iron oxide. Forming a layer, it provides an effect of providing a two-layered foundation cosmetic composition and its manufacturing method that can give a visual distinction and at the same time give a user a fresh and comfortable feeling like a lotion on use.

Hereinafter, the present invention will be described in detail with reference to specific examples.

The two-layer foundation cosmetic composition according to the present invention comprises 5 to 15% by weight of powder selected from the group consisting of titanium dioxide, kaolin, talc or a mixture of two or more thereof, 5 to 15% by weight of butylene glycol and the balance as water Characterized in that made. That is, the present invention is provided in the form of a composition comprising a mixture of titanium dioxide, kaolin or iron oxide as a powder component, and water and butylene glycol as an aqueous phase component, the cosmetic composition according to the present invention is a temporary for use Even after mixing, it is divided into two layers easily by standing and gives visually new feeling of cosmetics, and it is easily mixed by shaking to make it easy to apply to the skin. It is characterized by providing an excellent foundation cosmetic.

Titanium dioxide, kaolin, talc or a mixture thereof constituting the powder component in the above may be understood to be mainly used in the manufacture of color cosmetics in the industry as a sieving pigment, performing a masking function of the foundation according to the present invention It can be understood that. When the powder component is used in less than 5% by weight may have a problem that the masking function, which is a natural function of the foundation may not be sufficient, on the contrary, when the powder component exceeds 15% by weight, there may be a problem that the feeling of use is not smooth.

As the powder, kaolin may be preferably used. In particular, kaolin can improve the adhesion to the skin of the foundation cosmetic composition according to the present invention.

The butylene glycol constituting the aqueous phase moisturizes the skin and the effect may be insignificant when the butylene glycol is used at less than 5% by weight, and conversely, when the content is more than 15% by weight, the feeling of use may be deteriorated. .

The cosmetic composition may further include ethanol in an amount of 0.5 to 10% by weight based on the total weight of the composition. The ethanol functions to impart a refreshing feeling to the skin when the foundation cosmetic composition according to the present invention is applied to the skin. When the ethanol is used in less than 0.5% by weight may be insignificant, on the contrary, when the ethanol is more than 10% by weight may cause irritation and formulation stability problems on the skin.

The cosmetic composition may further include aluminum chlorohydrate in an amount of 0.01 to 5% by weight based on the total weight of the composition. The aluminum chlorohydrate functions to promote the separation rate of the aqueous phase layer and the powder layer when the foundation cosmetic composition according to the present invention. When the aluminum chlorohydrate is used in less than 0.01% by weight may be insignificant, on the contrary more than 5% by weight may have a problem in the stability of the formulation.

In addition, the method for producing a two-layer foundation cosmetic composition according to the present invention, (1) 5 to 15% by weight powder selected from the group consisting of titanium dioxide, kaolin, iron oxide or a mixture of two or more thereof butylene glycol 5 to 15 A dispersion step of mixing and dispersing together with the weight%; And (2) a mixing step of mixing the dispersion obtained in the dispersing step of (1) with water as a residual amount.

That is, in the method for preparing a two-layer foundation cosmetic composition according to the present invention, first, butylene glycol and powder components of titanium dioxide, kaolin, iron oxide, or a mixture thereof are first dispersed to obtain a stable dispersion, which is then dispersed in water. It is characterized in that the solid powder components are evenly distributed in the aqueous phase component, which is a mixture of water and butylene glycol, and at the same time can be easily separated when left.

After the mixing step of (2), further mixing 0.5-10% by weight of ethanol, 0.01-5% by weight of aluminum chlorohydrate, or a mixture of two or more thereof with the cosmetic composition obtained above, based on the total weight of the cosmetic. A second mixing step may be further included.
