Problems solved by technology

[0010] At the same time, the coating powders surface-treated with fatty acids, metal soaps, and metal salts have good skin adhesion and moisturizing touch, but compared with silicon compound surface-treated powders, they have poor water repellency and insufficient spreadability. It feels rough on the skin, etc. In addition, since the metal salt is adsorbed on the surface of the powder in the form of fine particles, the stability of the surface modification state is poor, and the metal salt peeling phenomenon occurs
In addition, there is still the problem of reduced color reproducibility when used with other silicon raw materials

Embodiment 1

[0043] Embodiment 1: Preparation of composite powder

[0044] According to the different configurations of the types and contents of the pressure-sensitive adhesive polymer monomers shown in Table 2, 13 kinds of composite powders were prepared by dispersion polymerization.

[0045] Table 2

[0046]

[0047] In the configuration listed in Table 2, the preparation process of composite powder P8 is as follows, except that different monomers are used in step 5), other composite powders are also obtained in the same way as composite powder P8.

[0048] 1) A double-jacketed reactor is installed, and an overhead stirrer is used to connect a circulating water bath. Thereafter, the temperature was set to 70°C, cooling water was circulated in the condenser, and a diaphragm was installed to isolate the outside air.

[0049] 2) Add 157g of methanol + 67g of distilled water into the reactor to prepare a dispersion.

[0050] 3) put 24g titanium dioxide (TiO 2 ; CR-50, Advanced Chemis...

Embodiment 2

[0056] Example 2: Preparation of cosmetics containing composite powder

[0057] Using the same ingredients, foundations containing composite powders P1 to P10 in Table 2 above were prepared.

Abstract

The present invention relates to composite powder having enhanced skin adhesiveness, since the surface of inorganic powder contained in a cosmetic material is evenly covered with a pressure-sensitive adhesive polymer, a cosmetic composition containing the same, and a method for preparing the same. A cosmetic material comprising the composite powder according to the present invention shows adhesiveness resulting from a pressure-sensitive adhesive polymer, thereby having excellent skin adhesiveness, enhanced coverage and lasting power due to the same, excellent oil dispersibility and spreadability when applied on the skin, and bringing light and refreshing feeling when used.

Description

technical field [0001] This application claims the benefit of priority based on Korean Patent Application No. 10-2015-0035098 filed on March 13, 2015, and at the same time, all the contents disclosed in the documents of this Korean Patent Application are included in this specification as a part of this specification middle. [0002] The present invention relates to a composite powder in which a pressure-sensitive adhesive (PSA: Pressure-sensitive adhesive) polymer is coated on the surface of an inorganic powder. The surface of the inorganic powder in the invention, the composite powder with improved skin adhesion, the cosmetic composition containing the composite powder and its preparation method. Background technique [0003] Makeup Cosmetics play an important role by correcting skin imperfections, emphasizing eyes and lips to make the appearance look good. In a blend of ingredients in color cosmetics, coloring materials are used to conceal blemishes or marks, giving the ...
