Description

[0001] Powder Composition with Good Coverage and Moisturizing Power [

The present invention relates to a powder composition, and more particularly, it relates to a powder composition which improves moisture retention by using a high amount of ester-based oil and natural wax, and makes a fine particle of a powder macroscopic, And a powder composition for excellent make-up.

Common make-up cosmetics include liquid foundation, loose powder for finish, and prest fact. Each product is characterized by its covering power and bright skin expressiveness, and additionally has a moist moisturizing characteristic. However, the liquid foundation has high coverage and moisturizing properties, but has limited spreadability. Loose powder has a bright and high spreading property, but low covering power. The prest fact has a high covering power and spreadability, but has a limitation in moisturizing because it is a powdered formulation.

In the makeup composition, the covering power and the moisturizing feeling are constantly required, but there is a great limit to the moisturizing effect especially in the powder formulations. If the moisturizing power is increased, a caking phenomenon tends to occur, and cosmetic clustering may occur during application of the product.

Korean Patent Publication No. 2010-0006707

Accordingly, the present inventors have repeatedly conducted research to provide a powder having a high covering power and a moisturizing effect. As a result, by using a low-viscosity ester oil and a natural wax dissolving at a skin temperature, a covering force and a moisturizing power are increased, And it became a powder with no aggregation phenomenon.

Accordingly, it is an object of the present invention to provide a powder composition having excellent covering power and moisturizing power.

In order to achieve the above object, the present invention provides a powder composition comprising an ester-based oil and a natural wax.

The powder composition according to the present invention is excellent in moisturizing power by the use of a high content of oil flow while having a high covering power, and the fine powder particles can be converted into macroscopically and uniformly applied without agglomeration of particles and cohesion of makeup.

Figs. 1A and 1B show photographs of a powder containing a high amount of oil and wax as macroparticles and a general loose powder observed under a microscope. Fig.

In the present specification, "loose powder" is a powder compact which is prepared by mixing a liquid component in a powder to prepare a slurry, and then removing the liquid component and pulverizing, compressing and molding the powder, Refers to a powder that is not processed and is manufactured by a dry process.
The present invention provides a powder composition, particularly a loose powder composition for makeup, excellent in covering power and moisturizing power.

In order to obtain such excellent coverage and moisturizing properties, the kind and content of the binder used in the composition are important.

In order to increase the covering power, the components of the powder used in the composition of the present invention may include extender pigments, pigments, white pigments, and fragrances which are commonly used in makeup products, and specifically, particles used as a component of the powder But are not limited to, titanium oxide, talc, mica, sericite, silica, nylon powder, silicone powder, polymethylmethacrylate (PMMA), boron nitride powder and barium sulfate.

At this time, the particles of the powder used in the present invention may be coated or uncoated. As the material used for the coating treatment, a dimethylpolysiloxane or an alkylsilane having a water resistance and an oil resistance can be used in combination, but the present invention is not limited thereto.

When the powder is coated in the present invention, the content of the coating material is used in an amount of 2 to 5% by weight based on the weight of the powder particles.

In the powder composition of the present invention, the content of the powder component is preferably 80 to 90% by weight based on the total weight of the composition. When the content of the powder is less than 80% by weight, the binder content in the whole composition becomes high, so that the spreadability is not good and lumps may occur. When the content of the powder is more than 90% by weight, the moisturizing effect of the powder is not high, . The powder component referred to herein refers to a component other than the powder binder, and includes the above-described extender pigment, pigment or white pigment, fragrance, etc. in a coated or uncoated state.

In the present invention, ester-based oils and waxes are used as powder binders in order to enhance the moisturizing effect. When the content of the pigment conventionally used in the makeup product is increased, cosmetic aggregation due to agglomeration of the powder appears. Also, when a high content of oil and wax is used here, powder agglomeration and caking occur. To solve this problem, the composition of the present invention uses a low viscosity ester-based oil and a wax melting at skin temperature.

As the ester oil in the powder composition of the present invention, cetyl ethylhexanoate, diisostearyl malate, squalane and the like may be used, but the present invention is not limited thereto. In particular, the ester-based oil used in the present invention preferably has a low viscosity.

In the present invention, natural wax is used to increase the moisturizing effect. Natural waxes include bees wax, carnauba wax, candelilla wax, caprylic * capric * myristic * stearic triglyceride, Hydrogenated vegetable oil, tribehenin (glyceryl tribehenate), Astrocaryum Mmurumuru seed butter, jojoba ester, and the like can be used. However, , But is not limited thereto. In particular, the natural wax used in the present invention has a melting point of 30 to 60 ° C, and such natural wax melts at the skin temperature and affects spreadability and uniform application of the product when applied to the skin.

In general, loose powder formulations do not contain a powder binder or contain only a small amount of 2 to 3% by weight. However, the powder composition of the present invention preferably contains the powder binder in an amount of 10 to 20% by weight based on the total weight of the composition in order to increase the moisture-holding power. When the content is less than 10% by weight, the formation of macroparticles of the powder particles is difficult and the moisturizing and covering power of the powder is not high. When the content exceeds 20% by weight, the spreadability of the powder is low, So that uniform application becomes difficult during coating.

The composition of the present invention uses a high amount of the above-mentioned ester-based oil and natural wax, whereby the particles of the powder are macerated. Or the powder prepared to have the composition according to the present invention is sprayed in the fluidized bed of air and the alcohol, the water-dispersed thickener, etc. are finely sprayed to enlarge the particles of the powder.

The composition according to the present invention can be formulated in the form of a powder composition, particularly a loose powder composition, which is a powder foundation which is combined with the advantages of a liquid foundation and loose powder, and is a makeup step through various steps such as foundation, loose powder, Can be a multi-functional product. The composition of this formulation may contain various bases and additives necessary and appropriate for the formulation of the formulation, and the type and amount of these components may be readily selected by those skilled in the art.

Hereinafter, the constitution and effect of the present invention will be described in more detail with reference to examples and test examples. The embodiments are illustrated to facilitate understanding of the configuration of the present invention, and the present invention is not limited to these embodiments.
