Description

Makeup cosmetic composition having improved absorbing abilities, coating properties and formability, and method for preparing the same}

The present invention relates to a makeup cosmetic composition with improved oil absorption, applicability and moldability by preparing it with a certain hardness including spherical powder and non-volatile oil, and a method for preparing the same.

Compressed powders form a line of makeup cosmetics such as Powder Pact or Twin Pact on the market. Compressed powders, unlike powdered powders, require stability in the molded state. That is, it is designed to withstand more than a certain physical impact in a compressed state because there should be no breakage due to external impact. In addition, unlike powdered powder, the amount taken on a cosmetic tool, generally a puff, should be constant and suitable for application.

In the general compressed powder composition designed in this way, cosmetic powder and oil binder, which are powder contents, are mixed, and these components are pulverized and compressed to be molded.

Oil binders are mainly used to increase the cohesiveness of the powder, to help form the powder during compression, to prevent breakage due to external impact, and to prevent the powder from flying when taking compressed powder as a cosmetic tool. However, if an oil binder is used, dusting can be reduced, but sometimes it gives a heavy feeling when applied to the skin.

The wet molding method is a molding method to reduce the disadvantages caused by the use of such an oil binder. In the wet molding method, a binder containing oil is mixed with the powder contents to make a slurry state, and the contents of the slurry state are filled in a container, and then oil is extracted through compression and suction to make compressed powder. The hardness of the formulation may vary according to the compression, and the function of the composition may also change according to the hardness. In addition, in this wet molding method, powder particles can be uniformly mixed by using an oil binder as a solvent compared to the dry molding method.

In addition, in general, the moldability of the compressed powder also shows a difference depending on the type of powder, and also shows a difference depending on the type of the powder coating agent. Generally, spherical powders such as nylon powder, PMMA powder, and silica can be used to improve the feeling of use of the powder. do. However, the spherical powder has a disadvantage in that compression molding is difficult when used in excess.

Therefore, there is an urgent need for research on a method for preparing a compressed formulation of a spherical powder that can improve moldability and applicability.

Hereinafter, it will be described in detail so that a person of ordinary skill in the art to which the present invention pertains can easily implement it. However, the present invention may be embodied in several different forms, and is not limited to the embodiments described herein.

The present invention comprises a spherical powder and a non-volatile oil,

It provides a makeup cosmetic composition, characterized in that the hardness measured according to JIS K 6301 is 5 to 12. The hardness may be preferably 8 to 10.

The hardness may be determined during the preparation of the composition, compression and some oil removal, and the hardness may affect moldability and applicability. When the hardness of the composition is excessively lower than the above range, since the amount of remaining oil is large, an excessively large amount of the composition may be smeared on the applicator during pay-off, and the hardness of the composition may gradually decrease due to continuous use. have. In addition, when the hardness of the composition is excessively higher than the above range, the formulation may be easily broken or cracked, and there may be disadvantages in that it is hardly smeared on the applicator or the like during payoff.

Also, the hardness measured according to JIS K 6301 can be measured using a JIS K 6301 A-type hardness meter.

The spherical powder is a powder having a spherical shape and is included in the makeup cosmetic composition to impart a smooth and light feel. The spherical powder has an effect of diffusing light in all directions and has excellent spreadability on the skin due to its shape. In addition, compared to plate powder, it has the effect of hiding skin defects such as pores and acne marks. Spherical powder has the effect of absorbing oil, and is lightly applied without clumping to the skin, so there is little irritation. Accordingly, the makeup cosmetic composition including the spherical powder has excellent adhesion to the skin and oil absorption. However, in the case of a makeup cosmetic composition containing a large amount of spherical powder, molding is difficult due to voids and repulsion between powder particles.

The present inventors researched on a makeup cosmetic composition that can be implemented in a compressed form for easy portability while having a high content of spherical powder. It was confirmed that this was improved.

The spherical powder usable in the present invention is not particularly limited, and inorganic particles, organic particles, and organic-inorganic composite particles commonly used in the art may be used.

In addition, the makeup cosmetic composition may further include a vinyl dimethicone/methicone silsesquioxane crosspolymer spherical powder, which is marketed as KSP-101 (SHINETSU).

At this time, the complexed spherical powder includes 70 to 99% by weight of hexamethylene diisocyanate/trimethylol hexyllactone crosspolymer spherical powder complexed with silica and polymethyl methacrylate and vinyl dimethicone/methicone silsesquioxane crosspolymer spherical It may contain 1 to 30% by weight of the powder.

The complexed spherical powder may have an average particle diameter (D50) of 1 to 10 μm, preferably 3 to 7 μm. If the average particle diameter of the spherical powder exceeds 10 μm, there may be difficulties in compression molding, and problems may occur in formulation stability such as breakage of the formulation when dropped, so it is appropriately adjusted within the above range.

The makeup cosmetic composition of the present invention may include a non-volatile oil in order to increase the bonding force between the spherical powder particles. The non-volatile oils include silicone oils including dimethicone, cyclomethicone and trisiloxane/dimethicone; ester-based oils including cetylethylhexanoate, isopropyl palmitate, isopropyl myristate, alkylbenzoate, diethoxyethylsuccinate and pentylerythrityl tetraisostearate; And mineral oil, isohexadecane, isodecane, undecane, squalane, a hydrocarbon-based oil comprising a hydrogenated polydecene alpha olefin oligomer and hydrogenated polyisobutene; may include at least one selected from the group consisting of and, preferably, the oil may be silicone oil, more preferably dimethicone.

In this case, the cosmetic composition may include 50 to 80% by weight of the spherical powder and 20 to 50% by weight of the non-volatile oil. If the amount of the spherical powder is larger than the above range or the amount of the non-volatile oil is small, powdering may occur, and moldability may deteriorate, so it is appropriately adjusted and used.

More preferably,

The present invention is 50 to 80% by weight of hexamethylene diisocyanate/trimethylol hexyllactone crosspolymer spherical powder complexed with silica and polymethyl methacrylate; and 20-50 wt% of dimethicone;

The manufacturing method is a wet process, and the wet state refers to a state in which the powder has flowability when more oil is included than the absorption/oil absorption capacity out of the limit value for absorption/absorption. It is prepared by mixing spherical powder and non-volatile oil, but adding oil until the mixture becomes a slurry.

In the wet state, the non-volatile oil completely coats around the powder particles, so you can expect a softer feel compared to general molding. After filling a plate with a certain amount of the slurry in the wet state, a part of the oil is extracted through compression and suction and compressed to form.

A powder cake-type composition prepared by a general dry process has relatively poor formability, and has a limitation in that adhesion is deteriorated when applied to the skin after drying. In addition, when a small amount of oil and powder are mixed, the moldability of the composition is not excellent, it is difficult for the oil to penetrate closely between the powders, and it is difficult to completely enclose the powder.

In order to overcome this limitation, in the manufacturing method of the present invention, the composition was prepared using a wet process, and after mixing a sufficient amount of oil with the powder, at the end, the required amount of oil was left and the oil was removed through the process of the present invention. The composition can obtain excellent moldability and the like.
