Description

Wet forming compact composition containing volatile silicone oil and silicone resin

The present invention relates to a cake-type wet molding fact composition, and more particularly, to a cake-type wet molding fact composition containing volatile silicone oil and silicone resin and manufactured to have excellent durability and soft feeling through wet molding. It is about.

A general cake-like fact composition is prepared by using a conventional method of preparing a sieving pigment, a pigment and a white pigment by mixing it in a mixer and then spraying a binder. However, it is already known that there is a limit to uniform mixing with this mixing method. In order to alleviate this drawback, a method called white injection (back injection) has been developed.

In the early wet molding process, the white injection method was generalized in the 1990s, and the contents of the fact powder powder before dispersing in a plastic dish were dispersed in a solvent mixed with IPA (Isopropyl alcohol) and water in a ratio to prepare the contents in a slurry type. Filling the slurry contents in the plastic dish through the method of white injection and suctioning a certain amount of solvent through the inhaler and putting it in a dryer to remove the remaining solvent to produce a cake-type facts such as eye shadow or blusher Widely used. In addition, since water and IPA are used as solvents, it is difficult to contain a large amount of powder coated with dimethyl polysiloxane or alkyl silane for uniform dispersion due to the hydrophilic properties. .

Recently, by using the emulsifier in the wet molding in the form of mixing the conventional solvent IPA or water, the uniform dispersion of the coated powder and the persistence due to the large amount of the coating powder is improved than before, but containing a large amount of coating powder Due to the use of emulsifiers for long time application, the persistence of sebum and sweat is poor and appears greasy and dull.

Korean Patent Publication Nos. 1999-40922 and 2003-50531, Japanese Patent Laid-Open No. 3-204806 and US Patent Publication No. 2005-0142089 disclose compositions prepared using silicone oil and silicone resin. However, the formulation of these compositions relates to a foundation or makeup base which is a liquid type, and in the case of such liquid type, it has a characteristic feature of a formulation in which an emulsifier must be generally used to uniformly disperse oil and water. As mentioned, the use of emulsifiers reduces the persistence of sebum and sweat due to prolonged application, resulting in greasy and dull skin.

Therefore, the present inventors have been researched to provide a wet forming pact with excellent soft feeling and durability, volatile silicone oil and volatile silicone oil without using any emulsifier to uniformly disperse the coated makeup powder in slurry form for improved durability. The present invention has been completed by discovering that a wet molded cake pact with excellent softness and durability can be prepared by uniformly dispersing a silicone resin mixed with a solvent and removing the mixed solvent through molding and drying. .

Accordingly, an object of the present invention is to provide a wet molding fact composition having excellent durability and soft feel.

In order to achieve the above object, the present invention provides a wet molding fact composition comprising a solvent in which the coated makeup powder is mixed with volatile silicone oil and silicone resin.

More specifically, the pact composition according to the present invention contains 60 to 70% by weight coated makeup powder and 30 to 40% by weight of a solvent mixed with a volatile silicone oil and a silicone resin to the total weight of the composition to be dispersed in a slurry phase It is molded and dried to remove the used volatile silicone, characterized in that it contains a base makeup powder and silicone resin.

The above and other objects, features and advantages of the present invention will become apparent to those skilled in the art from the following detailed description.

The wet molding fact composition according to the present invention is excellent in durability and soft at the same time by wet molding a coated makeup powder without using an emulsifier with a mixed solvent of volatile silicone oil and silicone resin.

Hereinafter, the present invention will be described more specifically.

Selection of the coating material and solvent type of the powder is very important in order to obtain the excellent durability and soft usability desired in the present invention in the wet molded facts.

In the present invention, a make-up powder coated with a coating material having excellent water resistance and oil resistance is used to prepare a wet molding fact that is soft and has excellent durability.

In this case, as the coating material, dimethylpolysiloxane or alkylsilane coating powder having water and oil resistance is generally used, but is not limited thereto. However, in order to improve the durability, it is usually desirable to apply a powder prepared by wet coating. In general, wet coating is to select the desired coating material and content of the powder to be coated, put it in the solvent, mix it, and then wash or volatilize the solvent so that only the coating material remains on the powder, and then heat-treat to complete the coating. Is performed.

On the other hand, the components of the makeup powder may include extender pigments, pigments and white pigments commonly used in makeup products, specifically talc, mica, sericite, silica, nylon powder, silicone powder, polymethylmeth Acrylate (PMMA), boron nitride powder, barium sulfate, and the like are used, but are not limited thereto.

In the pact composition according to the present invention, the content of the coated makeup powder is preferably 60 to 70% by weight based on the total weight of the composition, and when the content of the coated makeup powder is less than 60% by weight, the contents flow out during molding. Due to disadvantages, there is a problem in formability, and when it exceeds 70% by weight, it is difficult to uniformly disperse the coating powder. In addition, the powder component refers to a powder content prepared before molding into a cake content containing a sieving pigment, a pigment, a white pigment, and a flavor as a powder content coated with silicone or alkylsilane.

In the present invention, in order to uniformly disperse the coated makeup powder in a slurry form, a solvent in which a volatile silicone oil and a silicone resin are mixed in a weight ratio of 97: 3 to 99: 1 is used.

The content of the solvent in the fact composition according to the present invention is preferably 30 to 40% by weight based on the total weight of the composition, when the content is less than 30% by weight the content of the coated makeup powder is not uniformly dispersed, 40 If the weight percentage is exceeded, there is a problem in formability and cracking occurs even when the mold is dried.

Volatile silicone oils used in the present invention can be easily selected by those skilled in the art for commercially available products, for example, DC 200 (0.65cs) and dimethicones sold by Dow Corning (Dow Corning) DC 345 may be used, but is not limited thereto.

In addition, in the present invention, trimethylsiiloxysilicate is used as the silicone resin to maintain the cake form and improve the durability. The trimethylsiloxysilicate may also be easily selected and used by those skilled in the art for commercially available products, for example, KF-7312 F, KF-7312 J, KF-7312 K, KF-9001, X-21-5249, KF-9002, X-21-5250 or KF-9021 may be used, but is not limited thereto.

It looks at the process of wet molding the fact composition according to the present invention.

First, put the solvent mixed with volatile silicone oil and silicone resin together with the coated make-up powder in an all-round mixer, seal and mix for about 5 minutes, fill it with a certain amount in a fact-forming dish, and then mold it with a molding cloth. The solvent was removed by adsorption and dried in a dryer at about 60 to 150 ° C. for 2 to 12 hours to completely remove the remaining solvent.

Wet molded facts that can give good persistence and soft usability in accordance with the present invention can have conventional formulations, for example, can be formulated as twincakes, compacts, powder pacts and pressed powders and the like. The composition of each of these formulations may contain a variety of bases and additives necessary for the formulation of the formulation and are suitable, and the types and amounts of these components can be readily selected by those skilled in the art.
