Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a make-up cosmetic composition having a low viscosity and excellent stability in formulation stability and durability and an excellent formulation stability and durability,

More particularly, the present invention relates to a low-viscosity, water-in-oil type makeup cosmetic composition having excellent formulation stability and durability. More specifically, the present invention relates to a makeup cosmetic composition comprising a polyether-modified dimethicone and a polyether-modified dimethicone crosspolymer as emulsifiers, And a silicone-resin-containing in-oil type make-up cosmetic composition excellent in durability.

In general, water-in-oil type make-up cosmetics are hard to stabilize compared to water-in-oil type skin care cosmetics which do not contain powder or pigment or contain a small amount of less than 1%. Powders and pigments used in water-in-oil type make-up cosmetics are hydrophobic treated to impart water resistance and dispersed in oil phase of continuous phase.

In the case of make-up cosmetics in the water-in-oil type, the viscosity can be generally classified into solid, cream, lotion (or liquid), and two-layer separation type.

There are two methods for adjusting the viscosity of the water-in-oil type formulation. One is that the viscosity increases at more than one point as the water content of the dispersed phase increases (the oil content of the continuous phase decreases). This is believed to be attributable to the volume reduction of the dispersed phase (miniaturization of the emulsion particle size). And the other is to increase the viscosity of the continuous phase oil phase by using an oil phase thickening agent or to solidify the oil phase by adding wax. Based on this basic mechanism, each formulation has the following characteristics.

In the case of solid type (emulsion fact), wax is used as a continuous phase oil phase for solidification, and make-up is made using a make-up tool such as a puff because the pay-off is low. In order to obtain a high viscosity, a cream formulation has a small amount of water phase which is a dispersion phase, a relatively small amount of an oil phase which is a continuous phase, and a lot of oil phase thickening agent is used. This results in poor spreadability and insufficient uniformity of application. Although a water drop type product has been introduced which improves the spreadability of the emulsion particles when the emulsion particles are applied in a large amount in order to improve the emulsifying property of the cream formulations, there is a limitation in that uniform color reproduction is difficult. The lotion formulation is superior to the cream formulation because it has a higher content of oil phase and smaller amount of thickening agent. The two-layer detachable type has a higher oil content and less incremental content than lotion formulations. Thereby separating the pigment dispersed in the continuous phase oil phase. On the other hand, the usability is very light and excellent in spreadability, which makes it possible to make a fresh makeup. There is a limitation that the contents should be homogenized by shaking with each use.

Accordingly, low viscosity, water-in-oil type makeup cosmetics having excellent formulation stability are required.

Korean Patent Laid-Open Publication No. 2012-0057360 relates to a makeup cosmetic composition having excellent moisturizing and durability, wherein at least one selected from the group consisting of branched and crosslinked polyglycerin-modified dimethicone as an emulsifier is used to stabilize a large amount of polyol, Discloses a makeup cosmetic composition which is imparted with a moisturizing effect immediately upon application and has excellent moisture retention ability.

However, branched and crosslinked polyglycerin-modified dimethicone used as an emulsifier in the above-mentioned cosmetic composition has limitations in manufacturing a makeup cosmetic composition having excellent formulation stability and low viscosity.

Korean Patent Publication No. 2012-0057360

Accordingly, the inventors of the present invention have made various studies on the design of a composition for making a make-up cosmetic product having a low viscosity and excellent in durability and excellent in skin stability and wrinkle, When the ether-modified dimethicone copolymer is used as an emulsifier in an oil phase, the interfacial tension between the water phase and the oil phase is lowered by these interactions, so that emulsion particles are easily produced, stability is imparted to the produced system, And has excellent stability and continuity while having a low viscosity. Thus, the present invention has been completed.

Accordingly, it is an object of the present invention to provide a low-viscosity makeup cosmetic composition which is excellent in formulation stability and durability and has an excellent covering power against skin wrinkles and wrinkles.

≪ / RTI >

The makeup cosmetic composition according to the present invention improves the stability of the water-in-oil type emulsion while maintaining a low viscosity due to the interaction between the polyether-modified dimethicone and the polyether-modified dimethicone copolymer. .

Also, since the makeup cosmetic composition of the present invention has low viscosity, it has good spreadability and is easy to apply to the skin and smoothly applied to provide skin coverage and excellent coverage to wrinkles, thereby improving skin appearance. Such a makeup cosmetic composition has a high moisturizing and sustaining ability and can enhance the satisfaction of consumers.

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

The in-water type makeup cosmetic composition of the present invention comprises a polyether-modified dimethicone and a polyether-modified dimethicone copolymer as an emulsifier in an oil phase.

The polyether-modified dimethicone used in the present invention has a structure in which a polyether chain is branched in a silicone chain. Specifically, the polyether-modified dimethicone has a structure in which phage-9 polydimethylsiloxy ethyl dimethicone, lauryl phage- 9 polydimethylsiloxyl chilled dimethicone, and combinations thereof may be used.

It is preferable that the polyether-modified dimethicone is used in an amount of 0.1 to 5% by weight in the whole composition. If the content is less than the above range, the effect of stabilizing the powder can not be exhibited. On the other hand, when the content exceeds the above range, the viscosity exceeds 5,000 cps.

Further, the polyether-modified dimethicone copolymer used in the present invention has a structure in which the silicon chains are cross-linked with each other by polyether chains, specifically dimethicone / phage-10/15 crosspolymer, Lauryl dimethicone crosspolymer, and a combination thereof.
