Description

Chemicals with improved oil absorption, coating properties, and formability Cosmetic composition and preparation method thereof

The present invention relates to a color cosmetic cosmetic composition comprising spherical powder and non-volatile oil and prepared with fixed hardness, thereby improving oil absorption capacity, spreadability and formability, and a preparation method thereof.

Compressed powders are marketed to form a range of cosmetic products such as pressed powders or dual-purpose powders. Unlike powdered powders, compressed powders need to be stable in the shaped state. That is, in order to avoid fragmentation due to external impact, it is designed to withstand a force greater than a fixed physical impact in a compressed state. Also, unlike powdered powders, compressed powders are usually dipped in cosmetic tools such as puffs. Therefore, compressed powders should be designed so that cosmetic tools such as puffs can be applied to a fixed amount of compressed powder suitable for application, and the compressed powder should be compressed. The powder is designed so that when the powder is tapped with the puff to compress the powder, the powder will not fly off.

Compressed powder compositions designed in the foregoing manner are usually mixed with Cosmetic powders and oily binders, etc. of the final contents are formed by pulverizing and compressing the above-mentioned components.

Oil-based binders are mainly used to improve the cohesiveness of powders, thus helping to form when compressing powders, preventing breakage caused by external impact, and preventing flying powder when using cosmetic tools to pick up compressed powders. However, although the use of oil-based binders can reduce fly powder, there are cases where it creates a heavy feel when applied to the skin.

A molding method for reducing the above-mentioned disadvantages due to the use of an oily binder is a wet molding method. In the wet molding method, a binder including oil is mixed into the powder content to make a slurry state, the content in the slurry state is filled into a container, and then the oil is extracted by pressing and suction to produce a compressed powder . The properties such as the hardness of the dosage form vary according to the above-mentioned pressing, and the function of the composition also changes according to the above-mentioned hardness. In addition, compared with the dry molding method, this wet molding method uses an oily binder as a solvent, so that powder particles can be uniformly mixed.

The formability of the compressed powder generally differs depending on the type of powder, and also varies depending on the type of powder coating agent. Usually, in order to improve the use feeling of powder, it can be used together with spherical powder such as nylon powder, polymethyl methacrylate (PMMA) powder and silicon oxide. The spherical powder has excellent oil absorption ability when applied to the skin With good ductility, it is suitable for use as a material for make-up cosmetics. However, an excess of spherical powder has the disadvantage of being difficult to compression-form.

Therefore, there is an urgent need to study a method for producing a compressed dosage form of spherical powder which can improve moldability and spreadability.

The aforementioned spherical powder is a powder having spherical particles, and is included in a color cosmetic composition to impart a smooth and light touch. The spherical powder described above has the effect of diffusing light in all directions, and has excellent ductility to the skin due to its shape. In addition, compared to the tabular powder, it has the effect of concealing skin imperfections such as pores and acne marks. The spherical powder has an oil-absorbing effect and is applied lightly to the skin without agglomeration, so there is less powder sticking. Therefore, the color cosmetic composition including the spherical powder has excellent adhesion to the skin and oil absorption ability. However, a color cosmetic composition containing a large amount of spherical powder has a disadvantage that it is difficult to mold due to the voids and repulsion between powder particles.

The inventors of the present invention conducted research on a color cosmetic cosmetic composition with a high content of spherical powder and a form that can be compressed in a portable manner, and as a result, confirmed that when the spherical powder and non-volatile oil are included, the When the composition is prepared with a fixed hardness, the compression formability can be improved.
