Description

BACKGROUND OF THE INVENTION Concealer cosmetics composition with excellent adhesive property to the skin and a manufacturing method thereof

The present invention relates to a cosmetic composition having excellent skin adhesion and a method for manufacturing the same, and more particularly, to polyvinylpyrrolidone, trimethylsiloxysilicate, and acrylate/stearylacrylate/dimethicone methacrylate co. It relates to a water-in-silicone emulsion cosmetic composition having excellent adhesion and a method for producing the same, comprising a polymer in a specific component ratio.

In modern times, with the development of industrial society and the increase in social activities, the self-consciousness to actively express oneself is increasing, and the desire to use cosmetics to make one's own skin beautiful and healthy is increasing. Various compositions of water-in-water or water-in-oil emulsions have been developed to suit the needs. In general, the oil-in-water emulsion cosmetic has the advantage of being lighter in use and more refreshing when applied compared to the water-in-oil type, but has problems such as poor coverage and makeup persistence, and severe discoloration due to sebum. In the case of water-in-oil emulsified makeup cosmetics, the external appearance is oily, so it has excellent water resistance against sweat and oil resistance due to sebum, but there is a problem that the feeling of use is sticky compared to the water-in-oil type and stability during long-term storage is low compared to the water-in-oil type emulsion. . Therefore, in order to improve problems such as oiliness, stickiness, and heavy use, which are disadvantages of such water-in-oil emulsion cosmetic composition, a water-in-silicone emulsion cosmetic, a formulation using silicone oil having excellent spreadability (applyability) as the main component, was developed (Korean Patent Publication No. 2014-0062696, and Korean Patent No. 10-1301168), which also has a disadvantage in that skin adhesion is deteriorated due to the light feeling of use of the silicone component. In order to increase the adhesion of the cosmetic, it is necessary to contain an oil gel component of high viscosity, which lowers the stability of the water-in-silicone formulation, and the addition of a wax component causes another problem of inhibiting spreadability.

In order to solve the problems of the prior art, the inventors of the present invention have endeavored to develop a cosmetic composition having excellent skin adhesion while maintaining a light feeling of use of a water-in-silicone emulsion. Accordingly, the present invention relates to a cosmetic composition having excellent skin adhesion and a method for manufacturing the same, and more particularly, polyvinylpyrrolidone, trimethylsiloxysilicate, and acrylate/stearyl acrylate/dimethicone methacrylate. It relates to a water-in-silicone emulsion cosmetic composition having excellent adhesion including a copolymer in a specific component ratio and a method for producing the same. The cosmetic composition of the present invention, which significantly improved the conventional problems, is expected to be widely used in the field of beauty.

The present invention was developed to improve the low skin adhesion of water-in-silicone (W/S) emulsion cosmetics.

To this end, the present invention has an adhesive force comprising polyvinylpyrrolidone, trimethylsiloxysilicate, and acrylate/stearylacrylate/dimethicone methac relay copolymer in a specific component ratio as an oily or aqueous film forming agent. It provides an excellent water-in-silicone emulsion cosmetic composition and a method for producing the same.

The polyvinylpyrrolidone, trimethylsiloxysilicate, and the combination of three types of acrylate/stearyl acrylate/dimethicone methacrylate copolymers can complement the disadvantages of the water-in-silicone emulsion coating component.

In addition, the coagulation phenomenon of the water-in-silicone emulsion cosmetic composition can be solved by a combination of three types of polyvinylpyrrolidone, trimethylsiloxysilicate, and acrylate/stearyl acrylate/dimethicone methacrylate copolymer.

In addition, it is possible to solve the drying phenomenon of the water-in-silicone emulsion cosmetic composition by a combination of three types of polyvinylpyrrolidone, trimethylsiloxysilicate, and acrylate/stearyl acrylate/dimethicone methacrylate copolymer.

However, the technical problem to be achieved by the present invention is not limited to the problems mentioned above, and other problems that are not mentioned will be clearly understood by those of ordinary skill in the art from the following description.

Hereinafter, for a thorough understanding of the present invention, various specific details, such as specific forms, compositions and processes, are described. However, certain embodiments may be practiced without one or more of these specific details, or with other known methods and forms. In other instances, well-known processes and manufacturing techniques have not been described in specific details in order not to unnecessarily obscure the present invention. Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, form, composition, or characteristic described in connection with the embodiment is included in one or more embodiments of the invention. Thus, the context of “in one embodiment” or “an embodiment” expressed in various places throughout this specification does not necessarily represent the same embodiment of the invention. Additionally, particular features, shapes, compositions, or properties may be combined in one or more embodiments in any suitable manner.

Unless otherwise defined in the present invention, all scientific and technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs.

The present invention has excellent adhesion including polyvinylpyrrolidone, trimethylsiloxane sisilicate, and acrylate/stearyl acrylate/dimethicone methacrylate copolymer in a specific component ratio as an oily or aqueous film forming agent. It relates to a water-in-silicone emulsion cosmetic composition and a method for producing the same.

The polyvinyl pyrrolidone is a water-soluble polymer and is a linear polymer composed of 1-vinyl-2-pyrrolidone monomer. When added directly to the cosmetic composition, the composition is coagulated, so it is mixed with purified water to form a base to prepare a cosmetic. When polyvinylpyrrolidone mixed with purified water is applied to the skin, purified water is volatilized and applied with strong adhesion to the skin to form a film. As a water-soluble film, the skin dryness is less than that of a silicone-based film, but the thicker the film and the higher the content is, the lower the stability of the composition is.

The trimethylsiloxysilicate is a silicone-based resin component and is a siloxane polymer component. When added directly to the cosmetic composition, it causes coagulation of the composition, so it is mixed with silicone oil and added. When the trimethyl siloxysilicate component mixed with silicone is applied to the skin, the silicone component volatilizes, giving a feeling of close use and forming a strong film. However, it has a disadvantage of drying the skin due to its strong water repellency.

The acrylate / stearyl acrylate / dimethicone methacrylate copolymer (acrylate es / stearyl acrylate / dimethicone methacrylate copolymer) is acrylic acid (acrylic acid), methacrylic acid (metacrylic acid), and simple esters thereof It is a copolymer of at least one monomer selected from the group consisting of, stearyl acrylate, and dimethicone methacrylate, and is an oily coating agent. Acrylate/stearylacrylate/dimethiconemethac relay copolymer adheres to the skin to form a light film. Since the film is light and not hard, it has excellent feeling of use and moisturizing, but there is a disadvantage in that it is insufficient to maintain the lasting power of cosmetics compared to the strong film of polyvinylpyrrolidone and trimethylsiloxane.

The present invention compensates for these disadvantages by combining polyvinylpyrrolidone, trimethylsiloxysilicate, and acrylate/stearylacrylate/dimethicone methacrylate copolymer having the above disadvantages in a specific component ratio. The effect of letting go was confirmed. Therefore, when these ingredients are applied as a base with the combination disclosed in the present invention, there is an effect of stabilizing the cosmetic composition with excellent skin adhesion effect and maintaining skin moisture.
