Description

TECHNICAL FIELD [0001] The present invention relates to a compressed powder cosmetic composition having improved applicability and moldability,

The present invention relates to a compressed powder cosmetic composition comprising at least 20% by weight of the total weight of the composition of two or more spherical powders, which improves coating properties and compression moldability on a sticky coating film.

Makeup foundation is a cosmetic product applied to cover defects and express uniform skin color before color makeup. It is divided into liquid foundation, cream foundation, cake foundation and powder foundation according to the formulations. In recent years, in order to improve the portability of liquid foundation, a fact-shaped cushion foundation impregnated with a liquid foundation has become very popular. Among these, viscous foundations such as liquids and cushioning foundation exhibit natural coverage, and are effective for expressing fine and smooth skin, and are attracting the attention of consumers who desire transparent and natural skin expression.

Such a liquid or cushion foundation contains an excess of oil, and thus has a merit of soft spreadability, but has a disadvantage in that it is poor in skin adhesion and shows a feeling of oily feeling. Particularly, these foundations have a problem in that the ability to absorb sebum and sweat is lower than that of a powder-type foundation, so that the sustainability of the cosmetic film deteriorates due to aggregation, lifting and color change phenomenon due to sebum and sweat over time .

In order to solve the above problems, a cosmetic method has been used in which a powder type product such as a loose powder or a compressed powder fact having a good absorption ability is applied on a tacky film of a liquid or cushion foundation to fix the makeup. The spherical powder having a spherical shape of the particles is less likely to be clumped when applied to a sticky synthetic film, and natural skin can be expressed. Therefore, a cosmetic product having a high spherical powder content is more suitable for such use.

However, in the case of a compact type powdered cosmetic composition having a good portability, if the spherical powder is contained in an amount of 15 wt% or more, compression molding is impossible or dropping resistance can not be secured. Therefore, in order to realize a compressed powder formulation, a special spherical powder favorable for molding must be used alone, or a wet process should be added as disclosed in Korea Patent Publication No. 2013-055333. However, when a spherical powder favorable for molding is used alone, it is difficult to realize a feeling of good feeling and diversification of prescription, and there is a problem that dropping resistance is inferior. When a separate wet process is added, productivity and cost are inefficient, Resulting in problems such as a feeling of use and a decrease in the stability of the formulation.

Therefore, it is necessary to develop a new compressed powder cosmetic composition which can be formulated by a dry process, has excellent drop-resistance, and has excellent application property and feeling on a sticky synthetic film.

Korean Patent Laid-Open Publication No. 2013-055333, cosmetic composition for makeup correction and manufacturing method

In order to solve the above problems, the present inventors prepared a powder cosmetic composition comprising two or more kinds of different spherical powders, and the powder cosmetic composition thus prepared contains a spherical powder in an amount of 20 wt% or more, Molding ability, superior dropping resistance, excellent screening film duration, and boosting effect, thereby completing the present invention.

Accordingly, an object of the present invention is to provide a compressed powder cosmetic composition comprising 20 to 40 wt% of at least two spherical powders.

In order to achieve the above object, the present invention provides a compressed powder cosmetic composition comprising spherical powder, plate-like powder and oil binder,

Wherein the spherical powder contains at least two kinds selected from the group consisting of inorganic particles, organic particles and organic-inorganic composite particles in an amount of 20 to 40% by weight of the total composition.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Pressed powder cosmetic composition

The present invention relates to a cosmetic composition comprising at least two spherical powders selected from the group consisting of inorganic particles, organic particles and organic-inorganic composite particles, wherein the spherical powder is contained in an amount of 20 to 40% Thereby providing a powder cosmetic composition.

A spherical powder is a spherical powder, which is contained in a powder cosmetic composition to give a smooth and light texture. The spherical powder has an effect of diffusing light in all directions, and is excellent in concealing skin defects such as pores and acne marks compared with flake powder. In addition, the spherical powder has an advantage of absorbing oil when applied on a sticky synthetic film such as a liquid foundation or a cushion, and has an advantage that it is lightly applied without aggregation. Thus, the powder cosmetic composition having a high proportion of spherical powder is effective for natural skin-directing and has an effect of enhancing retention of a cosmetic film, and is suitable for fixation of a film and correction cosmetic.

However, in the case of a powder cosmetic composition containing a large amount of spherical powder, it is disadvantageous in that it is difficult to produce a fact type compressed powder formulation due to the pores and the repulsive force between the powder particles. That is, when the content of the spherical powder is 15% or more of the weight of the cosmetic composition, compression molding is generally difficult and it is difficult to realize a stable compression powder formulation because of high cracking even after molding.

The present inventors have studied a powder cosmetic composition that can be realized in the form of a compressed powder so as to be easily portable even when the content of the spherical powder is high. As a result, when two or more kinds of spherical powders of different kinds are mixed and used, It was confirmed that the dropping property was improved. The compressed powder composition thus prepared was lightly pulverized without agglomeration when used on a sticky synthetic film and showed a boosting effect of the cosmetic film.

The "boosting effect of a cosmetic film" as used herein means the effect of complementing the covering force of the cosmetic film when applied with a compressed powder cosmetic composition on the film, improving brightness and color development, increasing sustainability, and increasing uniformity. That is, when the maintenance and complementary properties of the cosmetic film are improved as compared with before the application of the compressed powder cosmetic composition, it can be said that there is a boosting effect of the cosmetic film.

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

The inorganic particles preferably use silica. The silica is a spherical spherical powder having a high oil absorption to maintain the consistency of the cosmetic film, has a low refractive index, has a high transparency, and has an advantage of applying different powders evenly. However, when a high content of silica is used, compression molding is difficult and the skin may be dried, so it is preferably used within 30 wt% of the total weight of the cosmetic composition, more preferably within 20 wt%.

The organic particles may include, for example, polystyrene, polymethylmethacrylate, polyethylene, nylon 6, nylon 12, ethylene / acrylic acid copolymers, polymethyl methacrylate / ethylene glycol dimethacrylate copolymers, polyallyl methacrylate / Ethylene glycol dimethacrylate copolymer, ethylene glycol dimethacrylate / lauryl methacrylate copolymer, crosslinked acrylate / ethylhexyl acrylate copolymer, polyurethane and combinations thereof. Of these, polymethylmethacrylate and ethylene / acrylic acid copolymers are preferred in terms of moldability as a compression powder formulation, lightweight spreadability, and ensuring foaming effect of a cosmetic film.

The organic-inorganic composite particles may be, for example, polymethylsilsesquioxane, silicone resin powder, organosilicon particles, silica surface-treated with an organic substance, and combinations thereof.

The silicone resin powder may be a silicone resin-coated organopolysiloxane elastomer powder such as silsesquioxane resin, more specifically, a vinyl dimethicone / methicone silsesquioxane crosspolymer. The organosilicon particles may be, for example, methylsilanol / silicate crosspolymers, and the silica surface-treated with the organic material may be, for example, silica coated with polydimethylsiloxane, but is not limited thereto.

The spherical powder preferably has an average particle diameter (D50) of 5 to 20 mu m. If the average particle diameter of the spherical powder exceeds 20 탆, it is difficult to perform compression molding, and there arises a problem in formulation stability, such as cracking of the formulation upon falling, so that it is appropriately controlled within the above range.

In the compressed powder cosmetic composition according to the present invention, the spherical powder may be used by mixing two or more kinds, and the combination thereof is not limited and may vary, but preferably includes at least one kind of inorganic particles and at least one kind of organic particles . In this case, the inorganic particles are preferably contained in an amount of 10 to 30% by weight in the whole composition and 5 to 20% by weight in terms of organic particles. When the above numerical range is satisfied, it can be molded into a compressed powder form without wet forming, and exhibits excellent drop stability. In addition, the boiling effect of the cosmetic film can be obtained by including the additive and the organic particles in the above numerical range.

According to a preferred embodiment of the present invention, the spherical powder comprises inorganic particles and organic particles, wherein the inorganic particles are silica and the organic particles are ethylene / acrylic acid copolymers.

According to another preferred embodiment of the present invention, the spherical powder comprises inorganic particles and organic particles, wherein the inorganic particles are silica and the organic particles may be a combination of polymethyl methacrylate and an ethylene / acrylic acid copolymer .

The compressed powder cosmetic composition of the present invention comprises a plate-like powder for imparting compressibility, covering power, skin adhesion and adhesion properties.

The type of the plate-like powder is not particularly limited in the present invention, and a plate-like powder commonly used in the art can be used. In this case, the plate-like powder preferably has an average thickness of 0.1 to 1.0 μm, an average particle diameter of 1 to 100 μm, an aspect ratio of 10 or more obtained by dividing the average particle diameter by an average thickness in terms of compression moldability, coverage, Do.

Specifically, the plate-like powder may be selected from the group consisting of Talc, Mica, Boron nitride, Barium sulfate, Alumina sericite, Kaolin, And Synthetic Fluorophlogopite. Preferably, talc is used. Talc is characterized by the absence of elasticity, and almost all types can be formed when the average particle size is less than 10 μm, and less dusting after molding and good dropping stability, which makes it suitable for forming compressed powder formulations. Talc powder having an average particle size of preferably from 4 to 9 μm, more preferably from 6 to 7 μm is preferably used because the larger the size of the talc powder is, the lower the denseness and the lower the formability.

The content of the plate-like powder is preferably 40 to 80% by weight of the total weight of the composition. When the content of the plate-like powder is less than 40% by weight, it is difficult to formulate the powder into a compressed powder. When the content of the plate-like powder is more than 80% by weight, the content of the spherical powder is lowered and a compacted powder cosmetic composition having less aggregation can not be obtained. Adjust accordingly.

The compressed powder cosmetic composition of the present invention comprises an oil binder for enhancing the bonding force between powder particles. The type of the oil binder is not particularly limited, and examples thereof include hexyl laurate, dicaprylyl carbonate, diisostearyl malate, butyleneglycol dicaprylate / Butylene glycol dicaprylate / dicaprate, Cetyl ethylhexanoate, Triethylhexanoin, Dicetearyl dimer dilinoleate, caprylic / capric triglyceride, An ester-based oil selected from the group consisting of Caprylic / Capric Triglyceride, Polyglyceryl-2 Triisostearate and Pentaerythrityl Tetraisostearate; Hydrocarbon oils selected from the group consisting of polybutene, hydrogenated polyisobutene and phytosqualane; A silicone oil selected from the group consisting of phenyl trimethicone and dimethicone. Of these, diisostearyl maleate or dimethicone is preferably used in terms of moldability and usability.

The oil binder is preferably contained in an amount of 5 to 20% by weight, more preferably 5 to 10% by weight, based on the total weight of the composition. If the content of the oil binder is less than 5% by weight, dry compressive molding is difficult, falling stability is poor, and the phenomenon of dusting of the powder occurs. When the content of the oil binder exceeds 20% by weight, Adjust properly within the range.

Meanwhile, the compressed powder cosmetic composition according to the present invention may further comprise a pigment for supplementing skin defects and imparting lustrous color. The kind of such a pigment is not particularly limited, and white or colored inorganic or organic particles that are commonly used in the art can be used.

Examples of the inorganic pigments include titanium dioxide, zirconium oxide or cerium oxide, surface-treated or surface-treated zirconium oxide, iron oxide (black, yellow or red), chromium oxide, manganese violet, ultramarine blue, chromium hydrate and ferric blue, aluminum powder and copper powder may be used.

Examples of the organic pigments include cochineal-derived dye, azo dye, anthraquinone dye, indigoid dye, xanthene dye, pyrene dye, quinoline dye, triphenylmethane dye, or fluororan dye.

The content of such a pigment is not particularly limited in the present invention, but is preferably in the range of 0.1 to 10% by weight based on the total weight of the composition.

In addition, the compressed powder cosmetic composition may further comprise at least one selected from the group consisting of a preservative, a moisturizer, a softener, a surfactant, an organic and inorganic pigment, an organic powder, an ultraviolet absorber, an antiseptic, an increasing agent, a bactericide, an antioxidant, , A blood circulation accelerator, a cold agent, and an antiperspirant agent.

As a result of the sensory evaluation of the cosmetic composition, the total scores of the cosmetic compositions of Examples 1 and 2, each containing two or three kinds of spherical powders, were superior to those of Comparative Example 1 containing only one spherical powder. In particular, the cosmetic compositions of Examples 1 and 2 were evaluated to be excellent in usability without causing agglomeration at the time of application, and also excellent in the covering power of the foundation and the supplement of the sustaining power.

The cosmetic compositions of Examples 1 and 2 were also excellent in color cosmetic persistence, coloring power, and covering power. When the cosmetic compositions of Examples 1 and 2 were applied and then color-matched, the sustaining power of both the shadow and concealer was superior to that of Comparative Example 1, and the coloring power and coverage were also improved.

From the above results, it can be seen that the compressed powder cosmetic composition according to the present invention exhibits the same or improved covering force and sustained power as the existing compressed powder cosmetic composition when applied on a cushion or liquid foundation coating, It is possible to express natural skin, and at the same time, it can be confirmed that cosmetic membrane boosting effect is enhanced by enhancing the coloring power and durability of color makeup.

Experimental Example 2: Evaluation of compatibility with cushion foundation

(1) a cushion foundation (hereinafter, referred to as "cushion") was applied, (2) a cushion was applied to the face, and The skin tone and the skin uniformity with time were measured when the compressed powder cosmetic composition (fact) 2 was applied.

The measurement was performed by using a Visia-CR manufactured by Canfield to photograph an image of the front face of the face and analyze the hue, saturation, and brightness of the face. Data analysis program was Image-pro plus from Media cybernetics. The skin tone corresponds to the brightness value, and the skin uniformity is derived from the standard deviation value of the saturation.

The results are shown in Table 3, and comparative photographs are shown in FIG.

Metrics Use cushion Use Cushion + Fact Before use Immediately after use After 4 hours After 8 hours Before use Immediately after use After 4 hours After 8 hours Skin tone

As a result of the experiment, it was confirmed that when the compressed powder cosmetic composition of the present invention is added to the cushion foundation, the skin tone and skin uniformity are both improved immediately after use. In case of skin tone, the improvement effect of more than 2 times was shown when the cosmetic composition of Example 2 was added, and the skin uniformity was also improved by 23%.

The effect of the compressed powder cosmetic composition of Example 2 appeared to be more pronounced in terms of durability. When cushion alone was used, the degree of improvement of skin tone after 8 hours remained at 60% level immediately after application, and skin uniformity was lower than before use due to agglomeration over time. On the other hand, in the case of using the compressed powder cosmetic composition of Example 2 in addition, it was confirmed that the skin tone improvement rate after about 8 hours was about 70% immediately after application, and the skin tone correction effect was maintained for a long time.

In addition, the skin uniformity was maintained for a long time because the compression powder cosmetic composition of Example 2 was less aggregated and the retention of the cosmetic film was excellent.

Experimental Example 3: Evaluation of drop-resistance

The drop powder property of the compressed powder cosmetic composition prepared in Production Example 1 was evaluated. Each of the compressed powder cosmetic compositions of Examples 1 and 2 and Comparative Example 1 was dropped at a height of 30 cm to confirm the number of cracks.

As a result, in Comparative Example 1, five out of ten were broken, and in Examples 1 and 2, only three of the ten were broken, and it was confirmed that the dropping resistance was excellent in comparison with Comparative Example 1 using only one spherical powder there was.

From the above experimental results, the compressed powder cosmetic composition according to the present invention is superior in compression moldability and drop-resistance even though it contains not less than 20% by weight of spherical powder, and when applied on a sticky synthetic film such as a cushion foundation, The effect of improving the uniformity and the effect of improving the sustainability of the cosmetic film are also excellent, and it can be confirmed that bright and uniform skin expression can be maintained over time.
