Abstract

The present invention relates to a powder type makeup composition containing powder in which sericite is granulated, wherein an average particle diameter of platy sericite is 0.1-5 um. A sericite particle is placed inside a solvent to make slurry. The slurry is sprayed and dried at the temperature of 200-450°C and is granulated. The powder type makeup composition provides a soft focus effect and natural coverage(concealment) by containing the powder in which platy particles are granulated. The powder type makeup composition provides a sense of soft use since the powder granulated when applied to skin is changed into a plate form. The powder type makeup composition also does not cause white turbidity phenomenon.

Description

[0001] The present invention relates to a makeup powder composition containing granules made of granules,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a minerals-based color cosmetic composition, and more particularly, to a minerals-based color cosmetic composition comprising a granule obtained by granulating serisite.

BACKGROUND ART [0002] Makeup cosmetics such as conventional powder foundations are mainly blended with extender pigments such as talc, mica, or ceriseite. When such an extender pigment is incorporated into a powder makeup cosmetic composition, it is expected that the adhesion of the skin and the whiteness on the skin when applied to the skin are improved, and further, an appropriate glossiness is imparted to the film applied on the skin, Extender pigments are commonly used in powder makeup cosmetics.

In addition, the characteristics of makeup cosmetics are required to have cosmetics such as having a proper covering ability (concealing ability) in addition to a feeling of unreliability, adhesiveness, or glossiness, having a soft focus effect, The stability of falling should be ensured while maintaining proper hardness.

Since the extender pigment does not have a high covering power (hiding power), it is general that a white pigment such as titanium oxide or zinc oxide is additionally added. However, since the titanium oxide fine particles have a high covering power (hiding power), it is possible to reduce the phenomenon of blistering of the coloring pigment such as red iron oxide, yellow iron oxide, or black iron oxide, which is an index of the skin. Further, since the titanium oxide fine particles have a relatively small average particle size of about 0.1 탆, it is difficult to uniformly disperse them in the powder cosmetic composition, and in some cases, they exist in a coagulated state in the cosmetic composition. If you apply this to the skin, it is not noticeable. When the above-mentioned cosmetic material is applied to the skin, the fine titanium oxide titanium may give a rough feeling to the skin, which may affect the feeling of use such as dripping on the skin.

In addition, in order to impart a soft focus effect, a spherical powder is used. In general, when spherical powder is applied to a cosmetic, powder falls and hardness-forming ability deteriorates, so that drop stability may be lowered. In order to solve such a problem, if an oil binder is added to the above-mentioned cosmetics more, the surface may be smudged, greasing, caking, or the like. The soft focus effect refers to the effect of naturally covering the irregularity, stain or dullness of the skin by using the diffuse reflection of light including spherical powder and the like.

As described above, the raw materials used in the make-up cosmetics have the respective problems as described above.

Disclosure of the Invention Problems to be solved by the present invention are to provide a minerals-based color cosmetic composition which does not contain titanium oxide, zinc oxide, spherical powder and the like, provides a natural whitening effect and a soft focus effect .

The present invention provides a powdered-type color cosmetic composition comprising a powder obtained by granulating serisite having an average particle size of 0.1 to 5 μm in a plate form. The inventors of the present invention have been studying to develop a cosmetic composition which is free of white pigment or spherical powder such as titanium oxide and has a uniform cosmetic film, excellent covering power (covering power) and soft focus effect, It has been confirmed that the above-mentioned effect is exerted when a powder obtained by granulating serisite is contained in a cosmetic composition, thereby completing the present invention.

The plate-like shape means a particle having a horizontal size larger than a size of a vertical direction and a thin plank-like shape in a horizontal plane. In the present invention, the grain size of the sericite plate can be measured with the longest diameter on the plane. The diameter may be measured through a scanning electron microscope (SEM) or particle size analysis (PSA), which is commonly used in the art, but is not limited thereto.

The composition according to the present invention does not substantially contain a white pigment such as titanium oxide or zinc oxide, or a spherical powder. More specifically, the composition may include a white pigment such as titanium oxide or zinc oxide, or a spherical powder in an amount of 3 wt% or less, preferably 1 wt% or less, more preferably 0.5 wt% or less based on the total weight of the composition , And most preferably none at all. The spherical powder refers to a powder having a spherical shape of particles, such as nylon 6 / nylon 12, silica, polymethylmethacrylate (PMMA), and the like.

In the composition according to the present invention, the granulated powder may be granulated by injecting cericite particles into a solvent to form a slurry, followed by spray drying. The ceraspace particles to be added to the solvent may be contained in an amount of 10 to 30% by weight, preferably 15 to 25% by weight, based on the weight of the solvent.

The spray drying may be carried out by spray drying at 200 to 450 캜 and granulation, preferably spray drying at 250 to 400 캜. If the spray drying temperature is higher than 450 ° C, the granules can not be produced in a desired shape and size. If the spray drying temperature is lower than 200 ° C, the drying speed is decreased, resulting in inefficiency in terms of yield and a large particle size at a relatively low temperature. It becomes difficult to prepare the furnace.

The solvent may be a solvent including at least one selected from the group consisting of water, isopropyl alcohol, and isobutyl alcohol, but is not limited thereto. Preferably, a mixed solvent of water and isopropyl alcohol can be used. The weight ratio of water to isopropyl alcohol may be from 3: 7 to 7: 3 (water: isopropyl alcohol), and preferably from 4: 6 to 6: 4 (water: isopropyl alcohol).

The granules obtained by granulating the cericite particles may have an average particle diameter of 10 to 80 탆, preferably 15 to 60 탆, and more preferably 20 to 40 탆. When the average particle diameter of the granulated powder is less than 10 μm, the dispersibility is decreased and the formulation stability is lowered. When the average particle diameter of the granulated powder is more than 80 μm, the coverage and the soft focus effect are deteriorated.

The granules in which the cericite particles are granulated may be contained in an amount of 0.5 to 40% by weight, preferably 3 to 35% by weight, and more preferably 5 to 30% by weight based on the total weight of the composition . When the granulated powder is less than 0.5% by weight, the coverage and soft focusing effects are insignificant. When the granulated powder is more than 40% by weight, the stability of the cosmetic preparation is deteriorated.

The formulation of the composition according to the present invention may be any one selected from the group consisting of pressed powder, loose powder, pressed powder foundation, face powder, compact, and two-way cake, but is not limited thereto. Preferably a press powder, a loose powder, or a pressed powder foundation.

The composition according to the present invention may include talc to impart coverage and soft focus effect. The talc may be contained in an amount of 10 to 90% by weight, and preferably 40 to 80% by weight based on the total weight of the composition.

The composition according to the present invention may contain an oil component commonly used in cosmetics and may be selected from mineral oil, liquid paraffin, squalane, lanolin derivatives, higher alcohols, ester oils, silicone oil, carboxylic acid, ceresin wax, , Polyethylene wax, paraffin wax, candelilla wax, microcrystalline wax, behenic acid, behenyl alcohol, beeswax, triethanol hexanoin, phenyl trimethicone, diisostearyl malate, octyldodecyl stearate Polyglyceryl-2-triisostearate, phenyltrimethicone, and the like may be used, but the present invention is not limited thereto. When phenyl trimethicone is preferably used, the purpose of the present invention is to provide a cosmetic formulation with less dusting and excellent drop stability.

The oil component may be included in an amount of 5 to 15% by weight, and preferably 6 to 10% by weight based on the total weight of the composition. When the oil component is less than 5% by weight, the skin adhesion and impact resistance are lowered, and when the oil component is more than 15% by weight, the adhesion and spreadability of the cosmetic composition are deteriorated.

In the present invention, the oily component means not only a liquid oily component and a solid oily component but also an organic surfactant such as sesquiisostearic oxydehyde and an ultraviolet absorber such as octylmethoxycinnamate.

The viscosity (25 캜) of the oil phase component may be 100 cps or less, preferably 30 cps or less. If the oil component having a viscosity exceeding 100 cps is blended, the adhesion and spreadability of the cosmetic composition are deteriorated, and the finish becomes pulverized and the glossiness is lowered.

(A) preparing a slurry by adding sericite having an average particle diameter of 0.1 to 5 μm in a solvent to a solvent; (b) spray drying the prepared slurry to prepare granulated powder; And (c) mixing the granulated powder with the cosmetic base at 0.5 to 40% by weight based on the total weight of the composition.

The spray drying may be performed by spray drying at 200 to 450 캜, preferably by spray drying at 250 to 400 캜, but is not limited thereto.

The granulated powder may have an average particle diameter of 10 to 80 탆, preferably 20 to 70 탆, and more preferably 30 to 60 탆.

EXPERIMENTAL EXAMPLES 1. Evaluation of Hiding Power and Feeling of Cosmetics Composition of Coloring Agent

The hiding power of the pressed powder prepared in the above Examples and Comparative Examples was measured. Lacar, which is the nitrocellulose resin used as the main component in this experiment, was supplied from Ahae Paint. 2 g of each of the prepared examples and comparative examples was mixed with 30 g of lacquer and then thinly coated on a white paper for measuring hiding power and a black paper with a thickness of 120 탆 using an applicator and then measured with a colorimeter (MINOTA) Were measured for a white paper portion and a black paper portion, respectively. The values (hiding power index) obtained after dividing the L value of the white paper by the L value of the black paper are shown in Table 3 below. The L value in the colorimetric system is a value indicating the degree of whiteness. The closer to white the value of L is, and the closer to black the value of L is. The hiding power index is represented by L value, and the closer to 1, the higher the hiding power.

In order to confirm the feeling of use of the pressed powder, blind test was performed on 20 women aged 20 to 45 years, and sensory evaluation was performed according to the evaluation criteria shown in Table 2 below. Sensory evaluation was performed by applying the examples and the comparative examples to the face of the subject, evaluating the sensation of use, in particular, the degree of comfort of the skin, the spreadability, and the feeling of adhesion. The results are shown in Table 3 as average values.

As shown in Table 3, Example 1 and Example 2 including granular sericite showed a higher score than the other comparative examples in sensory evaluation while having appropriate hiding power (covering power) Respectively.

In the case of Comparative Example 3, the pigment-grade zinc oxide and the titanium oxide were compounded in a larger amount than in the other comparative examples, so that they were relatively stiff and poor in feeling. Comparative Example 1 and Comparative Example 2 showed better results in sensory evaluation than Comparative Example 3, but lower scores than Examples 1 and 2 were obtained. In particular, Comparative Example 2 showed higher hiding power index than Example 1, but did not receive a good score in sensory evaluation. This is because Comparative Example 2 had a good hiding power but had a whitish appearance, which resulted in a poor score in the sensory evaluation because the make-up condition was uneven or the wettability was poor. In addition, Comparative Example 4 containing common sericite showed a somewhat lower score in the sensory evaluation than in Example 1 containing sericite granules, whereas Comparative Example 5 showed better hiding power and sensory evaluation And the score was low.

EXPERIMENTAL EXAMPLE 2 Dropping stability, moldability, and greasing & caking evaluation of a coloring-type cosmetic composition

Dropping stability was measured by a commonly used measuring method, and pressed powder was prepared, and the contents were filled in an aluminum dish, and then dropped freely 5 times at a height of 70 cm on a 3 mm rubber plate to confirm the degree of breakage. Normally, the drop stability was good when it was stable more than 3 times, and it was judged that it was unstable when it was stable less than 3 times.

The formability measurement method confirmed that the surface and the periphery of the plate were cleanly formed when the contents of the pressed powder were filled in the aluminum plate at the same pressure and time. If the surface of the pressed powder is unstable or the contents around the plate are torn or cracked, it is considered to be unstable or otherwise stable.

The grinding and caking measurement method is a method of filling the pressed powder contents into an aluminum plate to take the contents of the NBR puff with the force and pressure used by the consumer, There was a drawing phenomenon if there was a muddle phenomenon, and a caking phenomenon if there was a stain.

The results shown in Table 4 show that Examples 1 and 2 including granulated sericite have superior falling stability and moldability as compared with Comparative Example 1, .

In Comparative Example 5 containing 20% by weight of general sericite, the stability of dropping was stable twice, indicating unstable level, and it was confirmed that the moldability was unstable.

EXPERIMENTAL EXAMPLE 3. Evaluation of Make-up Condition of Make-up Composition

In order to ascertain the detailed make-up conditions of the above-mentioned Examples and Comparative Examples, 35 expert groups treating the make-up cosmetics professionally were selected and the make-up conditions for each item were evaluated and shown in Table 5 below. The makeup status of each detail item was visualized based on the following criteria.
