Description

 Highly adhesive powder coloring cosmetic composition

The present invention relates to a solid powder color cosmetics for improving skin adhesion and persistence, and more particularly, to adjust color tone as a diluent of colored powder in a powder makeup cosmetic composition, and to improve the malleability, skin adhesion, sweat and sebum absorption of the product. Method for surface modification of sieving pigments coated with mysterymic acid magnesium salt and dimethicone or microcrystalline crystalline wax and candelilla wax used for imparting gloss and color tone including sieving pigments surface modified by this method It relates to a cosmetic composition.

Solid powdery color cosmetics such as eye shadows are required for malleability, skin adhesion, skin affinity and molding stability. Conventionally, nylon, silica, PMMA, etc. have been used to improve malleability, and in order to improve adhesion, it is generally practice to increase oil binder content or to excessively use powder binder content such as metal soap. It was. However, when the content of the oil binder is excessively increased, a caking phenomenon occurs due to the characteristics of the solid powdery eye shadow, or a glazing phenomenon occurs, and when a large amount of metal soap is contained, the texture is degraded a lot. There is a problem that occurs.

Accordingly, the present inventors have diligently researched to overcome the problems of the prior art, and as a result, refrain from using an oil binder and a powder binder when the extender pigment of the solid color cosmetic is coated with a specific material, and the solid powder type eye shadow Solving the problem of powdering, and by increasing the skin adhesion of the pigment to confirm that it can increase the persistence of the makeup, the present invention was completed.

Therefore, the main object of the present invention is to provide a method for surface modification of extender pigments that suppresses powdering and increases skin adhesion.

In addition, another object of the present invention is to provide a powder color cosmetic composition comprising a extender pigment modified by the above method.

The present inventors have selected two methods to overcome the problems of the prior art, firstly, the extender pigment is first coated with Myristic acid Magnesium salts, and the second coating with silicon, Improved reagglomeration or aggregation.

Secondly, in order to increase the use of raw materials with low moldability due to the large particle size of powders such as pearlescent pigments, sieving pigments are surface-treated with microcrystalline waxes and candelilla waxes and have excellent moldability and skin adhesion. Made a road.

In the present invention, the extender pigment is used to adjust the color tone as a diluent of the colored powder in the powder pigment cosmetic composition and to impart the malleability, skin adhesion, sweat and sebum absorption and gloss of the product, for example, talc, seri Sites, mica, kaolin, nylon powder, silica and the like.

In order to achieve the object of the present invention, the present invention is to prepare a coloring pigment for coloring cosmetics 2 to 4, weight%, preferably 3% by weight and dimethicone 0.5 to 2% by weight, preferably 1% by weight of magnesium myristate Provided is a method for surface modification of an extender pigment, characterized in that the coating treatment is carried out by mixing sequentially or simultaneously.

In the surface modification method of the present invention, if the content of the magnesium myristate and dimethicone used for the coating treatment of the extender pigment is less than the above range, the bonding strength of the powder is weak, and if the content exceeds the above range, the improvement of agglomeration is reduced.

In addition, the present invention provides a powder color cosmetic composition, characterized in that it contains 10 to 55% by weight of the surface-modified extender pigment in the above-described method.

In the powder color cosmetic composition of the present invention, when the content of the coated pigment extender is less than 10% by weight, powder blowing, dropping stability, formability and adhesion are inferior, and when the content is more than 55% by weight, makeup spreadability is inferior.

In the powder color cosmetic composition of the present invention, either magnesium myristate and dimethicone may be used, but preferably the dimethicone has a viscosity of 100,000 to 700,000 CP. In a specific embodiment of the present invention, TALC M / DS 24R, TALC M / DS 46R of talc, which is talc coated with magnesium myristate and dimethicone, and SERICITE M / DS (FSE) of mycaine, which are coated with mica Used.

In order to achieve the another object of the present invention, the present invention is characterized in that the sieving cosmetics for coloring cosmetics, 4 to 6% by weight, preferably 5% by weight of microcrystalline wax or candelilla wax Provided are methods for surface modification of pigments.

In the surface modification method of the present invention, if the content of the micro-crystallin wax or candelilla wax used for the coating of the extender pigment is less than 4% by weight, the skin adhesion and molding stability is lowered, and if the content is more than 6% by weight, the wax is stiff. It has the disadvantage of giving a feeling.

In the surface modification method of the present invention, microcrystalline wax is a microcrystalline solid obtained from deoiling such as petroleum jelly and is a mixture mainly composed of isoparaffin of C31-C70, and candela wax is a wax obtained from stem of candelilla plant. It is purified and carbon number is about C16-C34.

In addition, the present invention provides a powder color cosmetic composition, characterized in that it contains 10 to 45% by weight of the extender pigment surface-modified by the above method relative to the total weight of the cosmetic composition.

In the powder color cosmetic composition of the present invention, when the content of the coated pigment extender is less than 10% by weight, moldability and adhesion are inferior, and when it is more than 55% by weight, the spread of makeup is disadvantageous.

The present invention is described in more detail below.

The present invention primarily uses sieving pigments of C-14 myristic acid magnesium salts having shorter carbon atoms than stearic acid salts having 18 carbon atoms in various metal soaps. By surface treatment, it is possible to make products with superior malleability and remarkably light touch than general metal soap surface treatment. In addition, the secondary surface treatment with Dimethicone improved the reagglomeration and aggregation of the pigment.

The present invention has been shown to improve the hydrophobic (Hydrophobic) and skin adhesion, the moldability of the product by surface treatment containing some of the extender pigment containing Magnesium Myristate 3.0% by weight, Dimethicone 1.0% by weight.

The present invention is to further reduce the stiffness of the wax itself by surface treatment of the sieving pigment containing 5.0% by weight of micro-crystallin wax or candelilla wax in another way to increase the adhesion of the powder, the skin adhesion and powder solid eye shadow which is a natural function It showed the effect of improving the molding stability of the figure. In addition, the binding force between powders was increased, reducing the amount of oil binder used in the solid powder eye shadow to realize the natural texture of the powder.

The method of coating the extender pigment in the present invention may be carried out by conventional methods such as adding the extender pigment and the wax to a mixer, followed by heat mixing or dipping or spraying in a hot melt wax or a wax solution dissolved in an organic solvent.

As an emulsion of the cosmetics used in the present invention, wax is generally referred to as lead as a higher monovalent or dihydric alcohol fatty acid ester. Natural waxes are roughly classified into solid waxes and liquid waxes according to their properties. Solid waxes are divided into two types, vegetable waxes and animal waxes, depending on the raw materials collected. There are few vegetable solid waxes.

Generally, solid waxes are similar to solid fats with high melting point, and liquid waxes are similar to fatty oils. Waxes are mostly crystalline solids at room temperature and generally have a lower specific gravity than fats. Soluble in almost all organic solvents such as alcohol and chloroform, but insoluble in water. Slightly more stable than fat, difficult to hydrolyze, and does not corrode with oxygen or bacteria in the air.

Hereinafter, the present invention will be described in more detail with reference to Examples. Since these examples are only for illustrating the present invention, the scope of the present invention is not to be construed as being limited by these examples. In these examples the content of ingredients is weight percent.
