Description

A method for producing a cosmetic composition containing a functional extender pigment and a cosmetic composition containing the functional extender pigment according thereto

The present invention relates to an extender pigment for use in a cosmetic composition, and more specifically, to a complex extender pigment having a core-shell structure and a method for manufacturing a cosmetic composition containing a functional extender pigment as a core remover, and a functional extender pigment according thereto It relates to a cosmetic composition containing.

The extender pigment used in cosmetics includes talc, kaolin, silica, and the like, and the white pigment includes titanium dioxide. In general, kaolin, talc, silica, and titanium dioxide are white powders that maintain skin spreadability, adhesion, and skin coverage, and are basic components of all cosmetics (Mitsui, 1998; Kani et al., 2007).

In addition, the extender pigment is used as a diluent for coloring pigments to adjust the color tone, greatly affect the feel of use, and also serve as a thickener and maintain the product.

When applied to the skin, it is important to ensure that makeup products that cover blemishes and smooth application can last a long time, especially in the sebum that is secreted, without making the makeup shiny or erased by sweat or sebum. Ingredients mainly used in cosmetic powders determine the feeling of use by a complex action such as spreadability, spreadability, and hygroscopicity of cosmetics according to the size and shape of the particles (Shim, 2008).

Depending on the composition of the cosmetic, in order to increase the affinity with the raw material, there are cases where the extender is surface treated and formulated. However, there is a disadvantage in that the oil absorption of the powder is lowered by surface treatment.

In the case of silicone resin powder, it is an extender pigment and its round physical shape with a very soft feel provides excellent lubricity and diffusibility. And the larger the particle, the better the fluidity such as the flow of water. When the particle size is small, the light is scattered and reflected, which enhances the soft focus effect, brightening the wrinkles, keeping the hidden facial imperfections, and reducing the sharpness of the makeup line with the light diffusion function. In addition, since methyl groups are distributed on the surface of the powder, it has a remarkable function in the cosmetic composition of the non-absorbent formulation without a separate surface treatment.

Silicone resin powder has the above advantages, but has a disadvantage of low oil absorption due to high crosslinking density.

As a related prior art, Registered Patent No. 10-1454730 "Cosmetics coating powder and method for manufacturing the same" describes "80 to 98% by weight of powder, and diphenylsiloxyphenyltrimethicone (diphenylsiloxyphenyltrimethicone ( 1 to 10% by weight of diphenylsiloxy phenyl trimethicone and 1 to 10% by weight of triethoxysilylethyl polydimethylsiloxyethyl hexyldimethicone as a second silicone oil coated on the powder Coating powder for cosmetics" characterized in that it has been provided.

In addition, as a related prior art, Patent Publication No. 10-2012-0021926 (silicone powder composite particles, manufacturing method thereof, and cosmetic composition comprising the same) as "more specifically, a core made of silicone powder; a shell made of a composite surrounding the core and the composite is a silicone powder composite particle in which the surface of the inorganic powder is coated with a silicone resin, a manufacturing method thereof, and a cosmetic composition comprising the same."

The present invention is a complex extender pigment having a core-shell structure with a significantly high oil absorption by remarkably improving the disadvantages of the low oil absorption of the conventional silicone resin powder, which was created to supplement the disadvantages of the silicone resin powder presented in the prior art and the prior art. And to provide a method for manufacturing a cosmetic composition for functional extender pigments and a cosmetic composition prepared accordingly.

In the case of the prior art and the prior art, in the case of surface treatment for manufacturing the core shell, the core is manufactured at a weight of less than 10%, whereas in the present invention, the core with a significantly high oil absorption rate is produced with a weight of 20% or more, resulting in a significant difference in the oil absorption rate later. An object of the present invention is to provide a method for manufacturing a composite extender pigment and a functional extender pigment cosmetic composition having a shell structure, and a cosmetic composition prepared accordingly.

By manufacturing, there will be a significant difference in the oil absorption rate in the future.

In addition, the conventional silicone resin powder is manufactured with a high crosslinking density, so the oil absorption is low and there is a difference depending on the cosmetic composition. However, the powder surface is smooth and the gloss is too high and the oil absorption is too low, which can cause greasiness on the skin, so a limited prescription is inevitable. as,

Although there was a disadvantage that the powder was settled in low-viscosity application products for the purpose of being heavy and light feeling, the functional extender pigment cosmetic composition according to the present invention has developed pores and thus the particles are light and do not sink in low-viscosity application products. effect that can be achieved.

In addition, the functional extender pigment cosmetic composition according to the present invention can be complexed with other functional materials due to the development of pores, so that it can be used as a functional complex powder by supporting functional oil or UV-blocking raw materials, which improves the convenience of products for customers. carry out

The cosmetic composition containing the functional extender pigment according to the present invention is added to a light diffusion plate, which is another application field, to improve the light diffusion function, and is coated on the film surface to minimize friction of the film.

Since the cosmetic composition containing the functional extender according to the present invention has a significantly developed pore compared to the conventional silicone resin powder, it shows a light diffusion effect different from that of the silicone resin powder without voids, so the customer has a light diffusion function of the light diffusion plate. can be adjusted more finely, and in the case of silicone resin powder without pores when coating on the film surface, when preparing a hazardous coating solution, it may sink in some coating solutions, making it difficult to use, but in the case of light silicone resin powder with developed pores There is an effect that can improve these negative aspects.
