Description

Granule Shape Composition having a reduced Scattering and A Manufacturing method

The present invention relates to a granular cosmetic composition and a method for manufacturing the same having reduced scattering, and more particularly, to reduce the scattering of the cosmetic to improve the skin adhesion while reducing the powder blowing phenomenon of the cosmetic to prevent the mixing of the cosmetic In addition, the present invention relates to a granular cosmetic composition and a method for preparing the same, which can prevent respiratory inflammation.

Cosmetics are articles used for the human body to clean and beautify the body to add charm, change the appearance brightly, or to maintain or promote the health of skin and hair. Especially, in the case of the hue products, the products which make fine powders (powder, fine powder) in the form of powders, cakes and spheres in order to express the natural skin color and point colors satisfy the functions desired by the consumers, Is produced.

However, recently, the Toxicology Program. "Toxicology and carcinogenesis studies of talc (CAS No 14807-96-6) in F344 / N rats and B6C3F, Human cosmetics such as mice (Inhalation studies). "Technical Report Series No. 421. September 1993.)

In addition, even if the contents of the existing powder products are powder, cake or spherical, when the contents are buried with puffs and applied to the skin, the contents of the puffs eventually become fine powders, There is a possibility of being scattered in the middle and aspirated into the respiratory tract.

General granulation of powder cosmetics and spherical cosmetic molding process is a method of making a granule by mixing a volatile solvent in powder cosmetics, volatilizing the volatile solvent contained in the granules (Korean Patent Registration No. 416,343), and dry powdery pigment There is a method of pulverizing, mixing and spraying and mixing the emulsion binder while maintaining the proper RPM with a router mixer to form a spherical cosmetic and dried (Korean Patent Registration No. 90,726).

In the granulation process, when the amount of the solvent to be mixed in the powder cosmetic is large, that is, when it corresponds to the knee length of the slurry state in the powder-liquid mixing system, granules are formed, but the cohesive structure between the particles is destroyed by external force. In this case, the granules are difficult to form due to the thixotropic effect of facilitating the flow and again forming a cohesive structure in the stationary state.

In addition, harmful ingredients such as talc containing asbestos have a problem that the fine powder itself may cause inflammation in the respiratory tract as well as mixing problems when used (“Mineral particles of varying composition induce differential chemokine release from epithelial lung cells: importance of physico-chemical characteristics ”, Annals of Occupational Hygiene Advance Access published January 7, 2005). Therefore, in the art, there is a need for the development of powder cosmetics having reduced scattering properties, which can prevent the above mixing problems and respiratory inflammation.

Therefore, the technical problem to be achieved in the present invention is to provide a granular cosmetic composition with reduced scattering properties that can prevent the incorporation of powder and respiratory inflammation caused by the powder in the granular cosmetic composition.

In addition, another technical problem to be achieved in the present invention is to provide a method for producing the granular cosmetic composition.

In order to achieve the above object, in the present invention, 10 to 15% by weight of titanium oxide, 7 to 12% by weight of kaolin, 5 to 10% by weight of corn starch, 3 to 7% by weight of cellulose, 3 to 7% by weight of zinc oxide, silica 3 to 7% by weight, magnesium stearate 3 to 5% by weight, iron oxide 2 to 5% by weight and mica 20 to 60% by weight, granular cosmetics, characterized in that the size of the granules range from 25 to 300㎛ To provide a composition.

In order to achieve the above another object, the present invention provides a method for producing a granular cosmetic composition comprising the following steps:

(1) 10-15 wt% titanium oxide, 7-12 wt% kaolin, 5-10 wt% corn starch, 3-7 wt% cellulose, 3-7 wt% zinc oxide, 3-7 wt% silica, magnesium stearate Mixing and crushing 3 to 5% by weight, 2 to 5% by weight of iron oxide and 20 to 60% by weight of mica;

(2) granulating the crushed mixture using ethanol or isopropyl alcohol as a solvent;

(3) selecting the granules in the granulated mixture in the range of 25 to 300 µm in size; And

(4) drying the screened yield.

The granular cosmetic composition according to the present invention is reduced in scattering phenomenon is reduced flying and skin adhesion is improved to prevent the mixing of the cosmetic as well as to prevent respiratory inflammation due to this, can be very useful in the art It is expected to be.

Figure 1 shows a method for producing a granular cosmetic composition of the present invention.
Figure 2 is an optical micrograph of the granular cosmetic composition of the present invention.
Figure 3 shows a method of confirming the scattering of the granular cosmetic composition of the present invention.

Granular cosmetic composition with reduced acidity of the present invention is 10 to 15% by weight titanium oxide, 7 to 12% by weight kaolin, 5 to 10% by weight corn starch, 3 to 7% by weight cellulose, 3 to 7% by weight zinc oxide , 3 to 7% by weight of silica, 3 to 5% by weight of magnesium stearate, 2 to 5% by weight of iron oxide and 20 to 60% by weight of mica, characterized in that the granule size is in the range of 25 to 300㎛.

The present invention has been devised in view of the fact that it is possible to reduce the scattering property by combining the components constituting the cosmetic in a specific combination ratio and adjusting the granules produced to a specific size, has a specific composition ratio as described above and the size of the granules 25 to The present invention was completed by confirming that by adjusting to a range of 300 μm, the hardness and scattering properties of the cosmetics may be reduced and thus, the powder blowing phenomenon of the cosmetics may be significantly improved while improving the skin adhesion.

In the granular cosmetic composition of the present invention, the titanium oxide is used in an amount of 10 to 15% by weight based on the total weight of the composition, and when the amount of titanium oxide is less than 10% by weight or more than 15% by weight, the present invention The effect of reducing acidity and decreasing hardness, which are the desired effects, cannot be obtained.

In the granular cosmetic composition of the present invention, the kaolin is used in an amount of 7 to 12% by weight based on the total weight of the composition, and when the amount of the kaolin is less than 7% by weight, the viscosity is lowered when mixed with the solvent and the flow is reduced. There is a problem in the formulation itself is worse, when exceeding 12% by weight has a problem of very rough application and gives a very dry feeling.

In the granular cosmetic composition of the present invention, the corn starch is used in an amount of 5 to 10% by weight based on the total weight of the composition, and when the amount of the corn starch is less than 5% by weight, the hardness is too low. If it exceeds 10% by weight, cosmetics may aggregate.

In addition, in the granular cosmetic composition of the present invention, the mica is used in an amount of 20 to 60% by weight based on the total weight of the composition, and when the amount of the mica is less than 20% by weight, the hardness of the granules is increased. If it exceeds 60% by weight, the cosmetic is rough.

Granular cosmetic composition of the present invention (1) 10 to 15% by weight titanium oxide, 7 to 12% by weight kaolin, 5 to 10% by weight corn starch, 3 to 7% by weight cellulose, 3 to 7% by weight zinc oxide, silica Mixing and crushing 3 to 7 wt%, magnesium stearate 3 to 5 wt%, iron oxide 2 to 5 wt% and mica 20 to 60 wt%; (2) granulating the crushed mixture using ethanol or isopropyl alcohol as a solvent; (3) selecting the granules in the granulated mixture in the range of 25 to 300 µm in size; And (4) it can be prepared according to the method comprising the step of drying the selected product.

In the cosmetic composition of the present invention, additives used in general cosmetics may be used. For example, cosmetically acceptable additives such as talc, perfume, color tone, preservative, antioxidant, and the like may be added.

The talc is preferably added in an amount of 0.1 to 20% by weight based on the total weight of the granular cosmetic composition of the present invention.
