Description

Makeup cosmetic composition with improved oil absorption ability, applicability and moldability and preparation method thereof

This application claims the benefit of priority based on Korean Patent Application No. 10-2016-0150209 of November 11, 2016 and Korean Patent Application No. 10-2017-0147055 of November 7, 2017. All content disclosed in the literature is included as part of this specification.

The present invention relates to a make-up cosmetic composition and a manufacturing method thereof having improved oil absorption ability, coatability and moldability by producing a certain hardness, including a spherical powder and a nonvolatile oil.

Compressed powder forms the market for makeup cosmetics such as powder pact or twin pact. Pressed powders, unlike powdered powders, require stability in the molded state. That is, since it should not be broken by an external impact, it is designed to withstand a certain physical shock abnormality in a compressed state. In addition, unlike the powder powder, the amount to be applied to a makeup tool, generally a puff should be a constant, suitable amount for application, it is designed so that the powder is not blown when tapping the compressed powder with a puff.

The general compressed powder composition designed in this way is mixed with the powder contents, such as cosmetic powder and an oil binder, and these components are pulverized and compressed to be molded.

The oil binder is mainly used to increase the cohesiveness of the powder, to aid in molding during powder compaction, to prevent breakage from external impact, and to prevent powdering when taking compressed powder with a makeup tool. However, the use of oil binders can reduce the appearance of dust, but can sometimes be heavy when applied to the skin.

The molding method for reducing the disadvantages caused by the use of such an oil binder is a wet molding method. In the wet molding method, a slurry containing oil is mixed with powder contents to make a slurry state, and after filling the slurry contents into a container, oil is extracted through compression and suction to make compressed powder. The compression may vary the hardness of the formulation and the like, and the function of the composition may also vary according to the hardness. In addition, the wet molding method may uniformly mix the powder particles using an oil binder as a solvent as compared to the dry molding method.

In general, the moldability of the compacted powder also varies depending on the type of powder, and also varies depending on the type of powder coating agent. In general, spherical powders such as nylon powder, PMMA powder, and silica may be used to improve the usability of the powder. The spherical powder has excellent oil absorption ability when applied to the skin, and is suitable for use as a material for makeup cosmetics. Do. However, spherical powder has a disadvantage in that compression molding is difficult when used in excess.

Therefore, there is an urgent need for a study on the preparation of compressed formulations of spherical powders which can improve moldability and applicability.

Hereinafter, the present invention will be described in detail so that those skilled in the art can easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

The present invention includes a spherical powder and a nonvolatile oil,

It provides a makeup cosmetic composition characterized in that the hardness measured in accordance with JIS K 6031 is 5 to 12. The hardness may preferably be 8 to 10.

The hardness can be determined during compression and some oil removal during the preparation of the composition, and the hardness can affect moldability and applicability. If the hardness of the composition is too lower than the above range, because the amount of oil remaining is large, too much of the composition may be buried at the time of pay off (applicator), etc., and the hardness of the composition may become lower 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 may have a disadvantage in that it hardly adheres to an applicator or the like during payoff.

In addition, the hardness measured according to the JIS K 6301 can be measured using a JIS K 6301 A-type hardness tester.

The spherical powder is included in the makeup cosmetic composition as a spherical powder to give a smooth and light texture. The spherical powder has an effect of diffusing light in all directions and has excellent application to skin by its shape. In addition, it has the effect of concealing the skin defects such as pores and acne traces compared to the plate powder. Spherical powder has the effect of absorbing oil, and is lightly applied without clumping on the skin, so there is little trouble. Accordingly, the makeup cosmetic composition containing the spherical powder has excellent adhesion and oil absorption ability to the skin. However, in the case of a makeup cosmetic composition containing a large amount of spherical powder, the molding is difficult due to the voids and repulsive force between the powder particles.

The present inventors have studied a makeup cosmetic composition that can be implemented in a compressed form so that the content of spherical powder is high and easy to carry, and as a result, when the composition is prepared with a certain hardness including spherical powder and nonvolatile oil, It confirmed that this improved.

In addition, the makeup cosmetic composition may further comprise a vinyl dimethicone / methicone silsesquioxane crosspolymer spherical powder sold by KSP-101 (SHINETSU).

In this case, the complexed spherical powder is 70 ~ 99% by weight of hexamethylene diisocyanate / trimethylol hexyllactone crosspolymer spherical powder complexed with silica and polymethyl methacrylate and spherical vinyl dimethicone / methicone silsesquioxane crosspolymer Powder may comprise 1 to 30% by weight.

The composite 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 is more than 10μm, it may be difficult in compression molding, and may cause problems in formulation stability such as breaking the formulation during dropping, so it is appropriately adjusted within the above range.

Makeup cosmetic composition of the present invention may contain a nonvolatile oil in order to increase the binding force between the spherical powder particles. The nonvolatile oil may be a silicone oil including dimethicone, cyclomethicone and trisiloxane / dimethicone; Ester-based oils, including cetylethylhexanoate, isopropyl palmitate, isopropyl myristate, alkylbenzoate, diethoxyethylsuccinate and pentylerythryl tetraisostearate; And hydrocarbon-based oils including mineral oil, isohexadecane, isodecane, undecane, squalane, hydrogenated polydecene alphaolefin oligomer, and hydrogenated polyisobutene. Preferably, the oil may be a silicone oil, more preferably dimethicone.

The manufacturing method is a wet process, and the wet state refers to a state in which the fluid becomes flowable when more oil is contained than the absorption / oil absorption capacity of the powder. It is prepared by mixing the spherical powder and the nonvolatile oil, but adding the oil until the mixture is in a slurry state.

In the wet state, the non-volatile oil completely coats around the powder particles, providing a smooth feel compared to normal molding. After filling the dish with a certain amount of the contents of the slurry in the wet state, a part of the oil is extracted through compression and suction and compacted.

Powder cake-type composition prepared by a general dry process is not relatively excellent in moldability, there is a limit that the adhesion is poor when applied to the dry skin. In addition, when a small amount of oil and powder are mixed, the moldability of the composition is not excellent, and oil is difficult to penetrate tightly between powders and it is difficult to completely surround the powder.

In order to overcome this limitation, the preparation method of the present invention was prepared by using a wet process, and after mixing a sufficient amount of oil with a powder, leaving the required amount of oil and removing the oil. The composition can obtain excellent moldability and the like.
