Description

Mascara composition with an excellent volume and lasting}

The present invention relates to a mascara composition having excellent volume and persistence, and more particularly, in a mascara composition containing a silicone resin powder, a silicone resin powder and a pigment can be improved due to the use of a silicone resin powder. Since it does not evenly distributed powder and agglomeration phenomenon, it relates to a mascara composition containing sorbitan olivate to improve the sense of volume and durability at the same time to solve this problem.

Because women's desire to be beautiful is so great, Asian women, who have less eyelashes than Western women, try to express their eyes more vividly and vividly by wearing mascara and eyeliner makeup. In particular, since the eyelashes of Asian women are thinner than those of Western women, there is a great desire to gain a sense of volume using mascara.

In mascara, the sense of volume means that the eyelashes are thicker than the original state and are thinned and richly produced. Many methods have been developed to give such a sense of volume.

Specifically, a mascara composition containing a silicone resin powder such as polymethylsilsesukioki acid and having an excellent volume feeling produced by a phase inversion emulsifision is disclosed in Japanese Patent Application Laid-Open No. 11-12132.

However, this miscara composition may provide excellent volume, but has a disadvantage in that powder blowing and agglomeration are severe.

Thus, the present inventors have been studied a method for solving the problem that the mascara prepared by the inverse emulsification method and containing silicone-based resin powder, powdering and agglomeration phenomenon is inferior in the sustainability, as a result, sorbitan It was found that the above problems can be solved when it contains an olibate, and the present invention has been completed.

In addition, the present inventors have found that the use of vinylpyrrolidone vinyl acetate copolymer in combination with the acrylic alkyl copolymer emulsion, which has been used as a conventional film forming agent, further improves the sustainability.

Accordingly, an object of the present invention is to provide a mascara composition that can be applied cleanly without agglomeration, excellent in volume, and excellent in adhesion, so that no powdering or agglomeration occurs and thus excellent persistence.

In order to achieve the above object, the mascara composition of the present invention is characterized by further containing sorbitan oleate in the composition containing the silicone resin powder.

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

In the present invention, the composition containing the silicone resin powder further contains sorbitan olivate and can be applied cleanly without agglomeration. The mascara composition is excellent in the sense of volume and excellent adhesion, so that no powdering or agglomeration occurs and thus excellent durability. To provide.

Silicone resin powders used in the present invention include polyorganosiloxane elastomer, polymethylsilseschioki acid, and the like, but polymethylsilsesukioki acid is preferably used. The form of the powder is not particularly limited, and a powder having a form such as porosity, irregular shape, plate shape, or sphere shape is appropriately selected and used. The amount used is 0.1-20% by weight of the total weight of the composition.

The mascara composition of the present invention further contains sorbitan olivate in addition to the silicone resin powder described above in order to simultaneously provide a sense of volume and durability.

Sorbitan olibate is a structure made of lipophilic part composed of olive-derived fatty acid and hydrophilic polyhydric alcohol group of sorbitan, has an amphipathic property, and has powder and pigment dispersion due to liquid crystal network structure. The state is uniform, and the wax shape is very compatible with the wax, which is useful as a powder and pigment dispersant in the oil phase.

The mascara composition of the present invention contains the sorbitan olivate described above in an amount of 1 to 20% by weight based on the total weight of the composition. It is too small to describe the effect of improving dispersibility when used in less than 1% by weight, and when used in excess of 20% by weight, the increase in hardness is too high to maintain a creamy hardness suitable for applying to the eyelashes. This is because there are difficult disadvantages.

On the other hand, mascara composition is one of the most important functions that the eye makeup cosmetics have to be powdery, bleeding phenomena because the black powder falls or smears under the eyes over time after the mascara makeup, but rather adverse effects occur Although one of the most important components affecting the persistence of the mascara composition is a film former, the conventional mascara composition has essentially contained a film former.

Typical examples of such film formers are acrylate alkyl copolymer emulsions. The composition of this invention also contains a film former with said silicone resin powder and sorbitan olibate.

In addition, the composition of the present invention further contains a vinylpyrrolidone vinyl acetate copolymer as a film forming agent to adjust the drying speed of the product to make it easier to apply, further improving the sustainability, excellent setting power and also clean Make-up was possible. The vinylpyrrolidone vinyl acetate copolymer in the composition of the present invention contains 10 to 50% by weight based on the weight of the acrylate alkyl copolymer emulsion. This is because if it exceeds 50% by weight, it is difficult to apply the product due to the fast drying speed when using the product, and less than 10% by weight of the effect is insignificant.

In addition to the above components, the mascara composition of the present invention may contain an aqueous phase component such as an oil phase component such as a wax and an antifoaming agent, a thickener and the like within the range that does not impair the object and effect of the present invention.

Since the method for producing mascara using the composition of the present invention requires fine emulsified particles in order to improve the feeling of volume, Phase Inversion Emusification, a phase-phase emulsification method, which is known as a method for making emulsified particles fine. (Phase Inversion temperature), D phase emulsification (surfactant Phase Emusification), it can be prepared using a method such as liquid crystal emulsification. Preferably, the aqueous phase containing the film-forming agent is gradually added to the oil phase containing the silicone resin powder and the sorbitan olivate, followed by mixing to prepare a reverse phase emulsification method in which the oil phase is emulsified in water.

Hereinafter, the present invention will be described in detail with reference to Examples and Experimental Examples, but the present invention is not limited only to these examples.
