Description

Powder composition with good coverage and moisturizing effects

The present invention relates to a powder composition, and more specifically, to improve moisturizing power by using a high content of ester-based oils and natural waxes, and to cover and moisturize without caking and makeup by making macro particles of powder It relates to an excellent makeup powder composition.

Common makeup cosmetics include liquid foundations, finishing loose powders and pressed pacts. Each product is characterized by covering power and bright skin expression, and additionally has moisturizing feeling. However, liquid foundations have high coverage and moisturizing, but there is a limit to the spreadability, and loose powder has a bright and high spreadability while low coverage. Pressed pact has high coverage and good spreadability, but there is a limit of moisturizing feeling as a powder formulation.

Covering power and moisturizing feeling are continuously required in makeup compositions, but especially in powder formulations, there is a big limitation on moisturizing feeling. If the moisturizing power is increased, the caking phenomenon is likely to occur, and when applying the product may cause a makeup clump.

Domestic Publication No. 2010-0006707

The present inventors have been researched to provide a powder having a high coverage and moisturizing feeling, by using a high viscosity of low-viscosity ester oil and natural wax soluble at the skin temperature to increase the coverage and moisturizing power, and the particles of the powder as a macro It became a powder without agglomeration.

Therefore, an object of the present invention is 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 the moisturizing power by using a high content of oils, while the cover power, and can be uniformly applied without agglomeration of the particles and agglomeration of the particles by turning the fine powder particles into a macro.

1A and 1B show microscopic observations of a powder of a powder containing a high content of oil and wax into a mark and a general loose powder under a microscope.

The present invention provides a powder composition excellent in coverage and moisturizing properties, in particular a loose powder composition for makeup.

In order to obtain such excellent coverage and moisturizing the binder type and content of the powder used in the composition is 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, fragrances and the like commonly used in makeup products, and specifically, as the particles used as a component of the powder Titanium oxide, talc, mica, sericite, silica, nylon powder, silicon powder, polymethylmethacrylate (PMMA), boron nitride powder and barium sulfate, and the like, but are not limited thereto.

At this time, the particles of the powder used in the present invention may be coated or uncoated. In general, the material used for the coating treatment may be water-soluble, oil-resistant dimethylpolysiloxane or alkylsilane, or a mixture of two materials, but is not limited thereto.

In the present invention, when using the powder coating, 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. If the content of the powder is less than 80% by weight, the binder content in the whole composition is high, so the spreadability is not good, and agglomeration may occur.If the content is more than 90% by weight, the moisture of the powder is not high. . The powder component referred to herein refers to components other than the powder binder, and includes the above-mentioned extender pigments, pigments or white pigments, flavors and the like with or without coating.

In addition, in the present invention, ester-based oils and waxes are used as powder binders in order to increase the moisturizing feeling. When the content of pigments commonly used in make-up products increases, cosmetic agglomerations due to agglomeration of powders appear. In addition, the use of a high content of oil and wax here causes agglomeration and caking of the powder. In order to solve this problem, the composition of the present invention uses a low viscosity ester-based oil and wax that melts at the skin temperature.

In the powder composition of the present invention, cetyl ethylhexanoate, diisostearyl malate, squalane, and the like may be used as the ester oil, but is not limited thereto. In particular, it is preferable that the ester oil used by this invention is low viscosity.

In addition, the present invention uses a natural wax to increase the moisturizing feeling. Natural waxes include bees wax, carnauba wax, candelilla wax, and caprylic * capric * mystic * steric triglycerides. Hydrogenated vegetable oil, tribehenin, glyceryl tribehenate, Astrocaryum Mmurumuru seed butter, jojoba ester, etc. It is not limited to this. In particular, the natural wax used in the present invention is a melting point of 30 ~ 60 ℃, such a natural wax is melted at the skin temperature will affect the spreadability and uniform application of the skin of the product.

In general, loose powder formulations do not contain a powder binder or use only a small amount of 2-3% by weight. However, the powder composition of the present invention, in order to increase the moisturizing power, it is preferable to contain the powder binder in an amount of 10 to 20% by weight based on the total weight of the composition. If the content is less than 10% by weight, it is difficult to form the macro particles of the powder particles, and the moisturizing feeling and the coverage of the powder are not high.If the content exceeds 20% by weight, the powder has low spreading properties. This makes it difficult to apply uniformly during application.

Since the composition of the present invention uses the above ester-based oils and natural waxes in a high content, the particles of the powder are macronized by this. Or by spraying the powder prepared to have a composition according to the present invention in a fluidized bed in the air, and fine spraying alcohol, water dispersion thickeners and the like can increase the particles of the powder.

The composition according to the present invention can be formulated in the form of a powder composition, in particular loose powder composition, which is a powder foundation that combines the advantages of liquid foundation and loose powder. It can be a multi-functional product that can reduce the The composition of this formulation may contain various bases and additives necessary for the formulation of the formulation and are suitable, and the type and amount of these components can be easily selected by those skilled in the art.

Hereinafter, the structure and the effect of the present invention will be described in more detail with reference to Examples and Test Examples.
