Description

The makeup cosmetic composition which contains oil-dispersing and a method of preparing according to the present invention.

The present invention relates to an oil-dispersible makeup cosmetic composition and a method for producing the same, and more particularly to a new type of dispersible makeup cosmetic composition using an oil thickener without using wax and a method for manufacturing the same.

Dispersion type makeup cosmetics generally applied in the existing cosmetic field can be divided into a solid foundation with excellent coverage and adhesiveness composed of oil-wax-pigment and a stick-type foundation with increased ease of use. In the case of a conventional dispersion foundation, it has been stabilized by solidifying with wax for the purpose of containing a large amount of powder for the purpose of excellent coverage and stabilizing it. However, it has the disadvantages of using heavy wax and thick makeup. In addition, the higher the content of the pigment, the less the degree of dispersion, the less uniformity of the coating and the high content of the pigment also has the disadvantage of feeling loose and stiff feeling. However, in recent years, as the trend of favoring light usability is reflected, there is a demand for a high-coverage, yet smooth and smooth formulation, and a new technology development is required to satisfy this.

Solid cosmetics can generally be divided into powder cosmetics, solid oil-based cosmetics, solid emulsion cosmetics and the like. In the case of emulsified cosmetics, it provides a refreshing and moist feeling that cannot be felt in powder cosmetics without water or cosmetics consisting only of oily ingredients, and gives a natural makeup effect because the makeup is not thick. Emulsion cosmetics have been studied a lot because of such advantages.

For example, silicone wax may be applied to prevent hardness change or shape change due to temperature change (Japanese Patent Laid-Open No. 2002-220321), or hydrogenated jojoba oil to improve the soft feel (Japanese Patent Laid-Open No. 2002-53425), and various studies have been conducted to apply spherical powder and hydrophobized powder (Japanese Patent Laid-Open No. 2000-327575), which has an effect of correcting skin irregularities and has excellent usability.

However, these studies do not observe the feeling characteristics according to the degree of phase change from solid to liquid, liquid to powder inherent in solid emulsion cosmetics. In other words, to improve the stability and overall feeling of the product by using or modifying the characteristics of each raw material, a large amount of wax is used to prevent the separation of the aqueous phase and the oil phase, and to maintain the stability of the solid form over time. Falls. In particular, the phase change to a solid, liquid, powder is not made clearly has a problem that the overall feeling when applied to the skin or the finishing makeup effect after application is inferior.

Accordingly, the present inventors have studied diligently to solve the above problems, and as a result of trying to prepare a new type of dispersion formulation different from the conventional one through the thixotropy effect while having a high coverage without using wax. The invention was completed.

The present invention is an oil-dispersed make-up cosmetics with excellent feeling of use which provides a moist feeling by applying smoothly and smoothly while applying smoothness, applying smoothness and applying dispersibility and closeness to the skin without using wax, and providing moisture. It is intended to provide a composition and a method of making the same.

In order to achieve the above object, the present invention is an oil characterized in that it contains 0.01% to 15.0% by weight of organic thickener, 1.0% to 30.0% by weight of oil and 5.0% to 60.0% by weight of solid powder pigment It provides a dispersible makeup cosmetic composition.

In addition, the present invention

a) adding an oil phase component to oil in a continuous phase and mixing the mixture uniformly at room temperature;

b) dispersing the organic thickener in oil in advance, warming it to dissolve, and then adding the organic thickener to the oily mixture of step a); And

c) adding a solid powder pigment to the mixture of step b) and then stirring the mixture uniformly to provide a method for producing a dispersible makeup cosmetic composition comprising a.

Hereinafter, the present invention will be described more specifically.

The organic thickener is characterized in that it contains Dextrin Palmitate (Dextrin Palmitate). Dextrin palmitate used as an oil thickener can control the degree of oil increase depending on the content range of the nature of the raw material, the degree of increase is slightly different depending on the type of oil.

 In addition, the content of the organic thickener is 0.01% to 15.0% by weight, preferably 1.0% to 10% by weight based on the total weight of the composition, the effect of the increase may be insignificant if the content is less than 0.01% by weight, 15 If the weight percentage is exceeded, the viscosity may be too high, resulting in poor formulation stability and usability.

The content of the oil is 1.0% to 30.0% by weight, preferably 10% to 25% by weight relative to the total weight of the composition. This is because if the content is less than 1.0% by weight can lower the applicability and impair the feeling of use, and if more than 30% by weight of the oil does not give a smooth adhesion occurs a slippery phenomenon.

In addition, the content of the solid powder pigment is 5.0% to 60.0% by weight, preferably 10% to 40% by weight based on the total weight of the composition, which is less than 5.0% by weight may have a negligible effect on the covering power, and 60.0% by weight. If it exceeds the percentage, the formulation stability and usability may decrease.

The dispersible makeup cosmetic composition is a solid type similar to the conventional one, but by containing an organic thickener without using a wax, the solid type is changed into a fluid gel by vibrating or stirring, in particular, with excellent covering power and stability, and when the solid is left again Since it has a thixotropic effect, it can be converted from solid to gel by the power applied when the product is used to maintain the coverage while applying smoother.After finishing the makeup, it adheres to the skin to provide moisture. It will have a good user experience. Please refer to Fig.
