Abstract

It provides a color cosmetic composition comprising a pearl and a high-viscosity oil binder, wherein the high-viscosity oil binder has a viscosity of 500 to 3000 mPa·s. Even though the color cosmetic composition contains a high content of pearls, the stability of the formulation is excellent. In addition, it has an effect of increasing gloss and adhesion.

Description

Color cosmetic composition comprising a high viscosity oil binder

It relates to a color cosmetic composition comprising a high-viscosity oil binder.

Eye shadow is a type of cosmetic product that is applied around the eyes to provide shading or a three-dimensional effect. Eye shadow is divided into powder type, stick type, cream type, emulsion type, pencil type (stick type), etc. depending on the formulation, and includes shading eye shadows that only shade around the eyes and sparkling pearls depending on the purpose. It is divided into pearl eye shadow and the like.

In the case of general pearl eye shadow, it has a pearl content of 30 to 40% due to the limit of formulation stability, and has a limit of pearl luster. In addition, when the content of the pearl is increased, the hardness is lowered and the cohesive force of the contents is weakened, which may cause problems during product filling and consumer use (KR Publication No. 10-2013-0008345).

Therefore, by using a high-viscosity oil binder including silicone wax (polymer alkyl dimethicone), medium-viscosity silicone oil, and high-viscosity ester-based oil (hereinafter referred to as high-viscosity oil binder), it overcomes the limitations of pearl luster and provides increased pearl compared to existing pearl eye shadows. There is a need to develop a pearl eye shadow having a stable formulation despite the content.

One aspect is to provide a color cosmetic composition comprising pearls and a high-viscosity oil binder, wherein the high-viscosity oil binder has a viscosity of 500 to 3000 mPa·s.

One aspect includes a pearl and a high viscosity oil binder,

The high viscosity oil binder provides a color cosmetic composition having a viscosity of 500 to 3000 mPa·s.

The silicone wax that determines the formulation in the high-viscosity oil binder is a paste phase at room temperature, and has the greatest effect on cohesion and adhesion between powders in the formulation.

The term "high viscosity" used in the present invention may have a viscosity of 500 to 3000 mPa·s, 1000 to 3000 mPa·s, 1000 to 2500 mPa·s, 1500 to 2000 mPa·s, or 1600 to 2000 mPa·s. If the viscosity is 1000 mPa·s or less, the property is liquid and flows without being fixed on the skin, and if it is 3000 mPa·s or more, the hardness is high and the application property is reduced. According to one embodiment, the viscosity of the high-viscosity oil binder according to the present invention may be 1600 to 2000 mPa·s / 30 ° C or less.
