Republic of Korea Patent Application Publication No. 10-2011-0130451

Accordingly, the present inventors have found that the volume of the composition immediately upon application does not significantly change the viscosity of the composition and also to produce a stable cosmetic composition for eyebrows or eyelashes without being easily separated or smeared on the eyebrows or eyelashes, the particle size is 20㎛ The present invention has been completed by knowing that the use of the above-mentioned huge powder and the use of the huge powder coated with a hydrophobic polymer can achieve the object.

Accordingly, an object of the present invention is to simultaneously exhibit the instantaneous volume and smooth spreadability by containing or mixing each of the giant powder coated with a hydrophobic polymer with a giant powder having a spherical particle shape and a particle diameter of 20 μm or more. And, to provide a cosmetic composition for eyebrows or eyelashes having persistence without powder falling and smearing.

The present invention provides a cosmetic composition for eyebrows or eyelashes containing spherical particle shape, each containing or mixed with a spherical spherical powder having a particle diameter of 20 µm or more and a giant powder coated with a hydrophobic polymer alone.

Hereinafter, the present invention will be described in more detail.

The large spherical powder of the present invention may have a spherical particle shape, and if the particle diameter is 20 µm or more, powders of all materials may be used.

The spherical spherical powder is composed of an organic powder selected from the group consisting of polymethyl methacrylate powder, nylon powder, urethane powder and silicon powder, talc, calcium carbonate, magnesium carbonate, kaolin, titanium oxide, zinc oxide, iron oxide and silica. The inorganic powder selected from the group can be used. Preferably, the organic powder may be used in terms of the effect of excellent sustainability without powder falling off, and more preferably, polymethyl methacrylate powder may be used.

 The particle shape of the large spherical powder is characterized in that the spherical shape (spherical shape), if the shape of the powder of the powder form of the plate-shaped or needle-shaped because the size ratio of the width and length is much different, thin and flat eyebrow or eyelashes It is difficult to expect the volume force to be put on, the bed form is a problem that the coating thickness is much different depending on the size of the diameter when placed on the eyebrow or eyelashes.

The diameter of the particles of the large spherical powder is characterized in that 20㎛ or more. If the particle diameter is smaller than 20㎛, it is difficult to increase the volume by applying a lot of times, but when using a large spherical powder with a particle diameter larger than 20㎛ it is possible to express a rapid volume This is because satisfaction with the makeup effect is increased.

The hydrophobic polymer coating the surface of the large spherical powder means a polymer having an oil affinity, and specific examples thereof include polymethyl methacrylate, polyethyl methacrylate, polypropyl methacrylate and trimethylsiloxy. At least one member selected from the group consisting of silicates, VP / Eicocene copolymers, acrylate / polytrimethylsiloxymethacrylate copolymers and acrylate / stearyl acrylate / dimethicone methacrylate copolymers, preferably Preferably polymethyl methacrylate or polyethyl methacrylate can be used.

The surface coating of the large spherical powder can be used a conventional coating method, for example a thin film coating can be used, but the method is not particularly limited .

In one embodiment of the present invention, the hydrophobic polymer may be contained at least 1 part by weight or at least 30 parts by weight based on 100 parts by weight of the spherical spherical powder to be coated when the surface of the giant spherical powder is coated with the hydrophobic polymer. Can be. In another embodiment of the present invention, the hydrophobic polymer is contained in 70 parts by weight or less or 50 parts by weight or less based on 100 parts by weight of the large spherical powder to be coated when the surface of the large spherical powder is coated with the hydrophobic polymer. Can be. In another embodiment of the present invention, the hydrophobic polymer is 1 to 70 parts by weight based on 100 parts by weight of the large spherical powder to be coated, when the surface of the giant spherical powder is coated with the hydrophobic polymer, more preferably Preferably from 30 parts by weight to 50 parts by weight. If the content is less than 1 part by weight can not expect the effect of improving the adhesion and persistence of the large spherical powder, when the content exceeds 70 parts by weight it is difficult to expect the creamy viscosity suitable for applying to the eyebrows or eyelashes.

In one embodiment of the present invention, the large spherical powder of the present invention may be contained in more than 0.1% by weight or 3% by weight relative to the total weight of the composition. In another embodiment of the present invention, the large spherical powder of the present invention may be contained in 20% by weight or less or 7% by weight or less based on the total weight of the composition. In another embodiment of the present invention, the large spherical powder of the present invention is contained in 0.1 to 20% by weight, more preferably 3 to 7% by weight relative to the total weight of the composition. If the content is less than 0.1% by weight, the volumetric effect does not appear properly. If the content is more than 20% by weight, the powder content is high, so the viscosity of the content may be increased, so that it may be applied stiffly and evenly attached to the eyebrows or eyelashes. Eyebrows clump together.

The cosmetic composition for eyebrows or eyelashes of the present invention can be used by mixing together a large spherical powder and an uncoated large spherical powder coated with a hydrophobic polymer. In this case, the weight ratio of the large spherical powder and the uncoated large spherical powder coated with a hydrophobic polymer is preferably 1: 4 to 4: 1. If the weight ratio of the large spherical powder and the uncoated large spherical powder coated with the hydrophobic polymer is less than 1: 4, it is difficult to increase the adhesion of the large spherical powder significantly, which causes a problem of slight powder falling. If it exceeds, the persistence by the large spherical powder is improved, but there is a problem in that the oil affinity component is increased so that smearing on the sebum component may occur.

The cosmetic composition for eyebrows or eyelashes of the present invention may contain, in addition to the above components, an emulsifier, a wax, an antifoam, a preservative, a thickener, a pigment, and the like within a range that does not impair the object and effect of the present invention .

The present invention simultaneously exhibits the instantaneous volume and smooth spreadability by containing or mixing each of the spherical particle shape and the spherical spherical powder having a particle diameter of 20 µm or more together with the spherical spherical powder coated with a hydrophobic polymer, alone or in combination. It is possible to provide a composition for eyebrows or eyelashes having persistence without powder falling off and smearing.
