Description

Powder Form Oil-Free Makeup Cosmetic Composition Comprising diatomaceous earth and Starch}

The present invention provides a powder foam oil-free makeup cosmetic composition comprising diatomaceous earth and starch (STARCH). More specifically, the present invention relates to a hypoallergenic oil free face makeup cosmetic containing diatomaceous earth and starch, and 100% without using oil that can cause skin trouble and inflammation using the amorphous nature and starch of diatomaceous earth. The present invention relates to a makeup cosmetic composition using only powder.

Makeup cosmetics can be classified into two types: base makeup groups such as two-way cakes, foundations, and face powders, and point makeup groups such as lipsticks and nail cosmetics. It may be classified into a dispersible type such as a skin cover and a lipstick and a powder type such as a two-way cake and a face powder. Makeup cosmetics have the function of covering or concealing the flaws of the skin and giving the beautiful color, that is, to beautify the skin, and to protect the skin such as nourishing, converging effect, moisturizing function and protecting the skin from UV rays. It performs the function.

Generally, the face makeup powder contains 3.0-10.0% of silicone oil and mineral oil. Face makeup powder is applied to the skin in a powdered state, so it is important to formulate the prevention of powder pulling and dryness and dryness at the beginning of makeup. However, oil-containing face makeup powders not only reduce sebum absorption ability, which is inherent, but also cause oil-induced irritation in sensitive skin.

In the case of the face makeup powder containing oil, to increase the oil absorption capacity, the oil content is lowered or the silica content is increased, which has the opposite result of increasing skin pulling, drying, and powdering. Due to this, the face makeup powder may be said to be ideally free from powdering, skin pulling, and dryness while maintaining high absorption capacity.

Diatomaceous earth, on the other hand, is a kind of fossil soil in which debris of single-celled plants is deposited on the seabed or the bottom of the sea. It is capable of extracting silica from the underwater environment and constructing its own rigid skeleton structure. The diatomaceous sedimentary rocks formed by the sedimentation of the diatom skeleton due to its rapid action are mostly composed of hydrous amorphous silica, and the particle size is 3-10. Μm, oil absorption 1.8-2.5 cc / g, specific surface area 40.0-60.0 m ² / g. Although it has similar characteristics to general mineral silica, diatomaceous earth is a type in which various shapes such as plate, needle, and spherical types are mixed, while mineral silica has a spherical shape. As a result, its malleability is relatively low, but it maintains high oil absorption and improves skin adhesion and alleviates dusting.

Rice starch (STARCH) is generally used for baby powder, and has a particle size of 3-10 μm, oil absorption of 0.7-1.3 cc / g, and specific surface area of 30.0-50.0 m ² / g. It has a spherical shape and is used to reduce skin irritation and increase malleability.

When using the above-mentioned diatomaceous earth and rice starch in the preparation of powder foam makeup cosmetic composition, it is judged that it is possible to manufacture a makeup composition which exhibits high oil absorption ability and at the same time improves the feeling without using an oil component. However, there are no patents and literatures on powder powder makeup cosmetic compositions containing diatomaceous earth and rice starch.

Numerous papers and patent documents are referenced and cited throughout this specification. The disclosures of the cited papers and patent documents are incorporated herein by reference in their entirety to better understand the state of the art to which the present invention pertains and the content of the present invention.

The present inventors earnestly researched to develop a powder type makeup cosmetic composition that is excellent in makeup persistence and can significantly reduce skin troubles.

As a result, when diatomaceous earth is used, it is possible to exhibit high oil absorption ability due to the amorphous characteristics of diatomaceous earth, and when starch is used together with the above-mentioned diatomaceous earth, it is reduced by the use of the diatomaceous earth due to the morphological characteristics of starch. The present invention was completed by discovering that the usability can be remarkably increased, and consequently, even the use of an uncoated powder without using an oil component is excellent in makeup sustainability and can significantly reduce skin troubles.

Accordingly, the present invention provides a powder type makeup cosmetic composition comprising diatomaceous earth and starch.
