Description

Powder type cosmetic composition for eye make-up}

It relates to a powdery eye makeup cosmetic composition.

Eye makeup products can be divided into mascara, eyeliner, eye shadow, and eyebrow. Among them, the eye shadow should have excellent adhesion to skin, ease of molding, glossiness, and spreadability.

In order to manufacture an eyeshadow with excellent glossiness, an attempt was made to develop an eye makeup product in a compressed powder form by including a high content of pearl powder and oil.

However, when the oil is excessively contained, the powder in the composition is not powdery, but agglomerates like a sphere or a dough, and thus the moldability is very deteriorated. Therefore, the content of the oil used to make the compressed powdery eye makeup product has been limited to a low level. In addition, if the composition contains an excessive amount of oil, there is a problem in that the surface is hard after compression and a caking phenomenon in which no more powder can be taken is caused, and thus the payoff is significantly reduced.

Accordingly, there is a need to develop an eye makeup cosmetic composition in a compressed powder form excellent in glossiness but excellent moldability, spreadability, and adhesion by containing a large amount of pearl powder and oil.

One aspect is an eye makeup cosmetic excellent in formability, spreadability, glossiness, and spreadability because it can be formulated in a compressed powder form while containing a large amount of pearl powder by excessively containing two or more oils containing low-viscosity silicone oil and high-viscosity oil It provides a composition and a method for preparing the cosmetic composition.

One aspect is an oil portion comprising a low-viscosity silicone oil and high-viscosity ester oil having excellent compatibility; And it provides an eye makeup cosmetic composition comprising a powder portion comprising a pearl powder.

The cosmetic composition according to an embodiment may be a composition having excellent moldability, which may be formulated in a compressed powder form while containing excessively high oil and pearl powder. Typically, in the eye makeup product, oil having a high refractive index and high viscosity is used to maximize the glossiness and improve the adhesion of the powder to the skin. However, if the composition contains excessively high oil with a high refractive index and viscosity, there is a problem that the moldability is deteriorated, and the surface is hard after compression, and a caking phenomenon, which is difficult to take powder, appears, resulting in a problem that the payoff is reduced. However, the cosmetic composition according to one aspect includes low-viscosity silicone oil and high-viscosity oil in an appropriate proportion to the oil part to solve the above problems, and can be manufactured in a compressed powder form, but has excellent spreadability, gloss, and adhesion, and is useful for eye makeup products. Can be used.

The composition comprises an oil portion comprising low viscosity silicone oil and high viscosity oil.

In the present specification, “low viscosity silicone oil” is not limited to any silicone oil used in a cosmetic composition, and may include dimethicone or cyclomethicone.

The low-viscosity silicone oil may have a kinematic viscosity of 10 cSt to 50 cSt. Low-viscosity silicone oil has an effect of preventing the powdery agglomeration, and this effect is stronger as the oil has a lower viscosity. Since the silicone oil has a low viscosity, it is possible to improve the agglomeration phenomenon of the powder phase containing a high content of the pearl powder and have excellent spreadability.

The low viscosity silicone oil may be non-volatile. When the kinematic viscosity of the low-viscosity silicone oil is 5 cSt or less, it is preferable to use a non-volatile low-viscosity silicone oil since the volatility increases and evaporates during cosmetic preparation.

Generally, silicone oil and high-viscosity ester-based oil have poor compatibility, and thus, when a composition in which they are mixed is applied to the skin, there is a problem that it does not adhere to the skin and breaks down. However, the low-viscosity silicone oil contained in the cosmetic composition according to one aspect has excellent compatibility with some high-viscosity ester-based oils at room temperature.

In the present specification, "high-viscosity ester-based oil" is not limited to any of the high-viscosity ester-based oils generally used in cosmetic compositions, for example, diisostearyl malate, octyldodecylstearoyl stearate, Hexyl laurate, ethylhexyl palmitate, ethylhexyl stearate, cetyl ethylhexanoate, isocetyl ethylhexanoate, isocetyl myristate, isopropyl myristate, neopentyl glycol dicaprate, triethylhexanoin, and iso Nonyl isononanoate may include one or more selected from the group consisting of.

The high-viscosity ester-based oil may have a viscosity of 1500 mPa · s to 3000 mPa · s. The high-viscosity ester-based oil is used to maximize the gloss of the eye makeup cosmetic composition and to improve the adhesion and adhesion between the skin and the powder by having a high viscosity and a high refractive index. There is a problem that a caking phenomenon occurs on the surface after firing, so that the payoff is significantly reduced, and thus it is difficult to be included as a high content. However, the composition according to one aspect includes a high-viscosity ester-based oil and a low-viscosity silicone oil together, and thus includes a high-content high-viscosity oil, but does not cause a caking phenomenon and has excellent gloss.

In the composition, the low-viscosity silicone oil: high-viscosity ester-based oil may be included in a mixture of about 1: 0.1-0.5. By adjusting the content of the low-viscosity silicone oil and the high-viscosity ester-based oil at the ratio, it is possible to formulate the compressed powder form by eliminating the clumping phenomenon, which is the limit point of the high-viscosity oil, while maintaining the powder bonding strength of the high-viscosity ester-based oil. When the ratio is out of the above range, when the cosmetic composition is taken, the powdering may be severe, the phenomenon may be caused by an external impact, or a problem may arise in the container containing the composition.

In the composition, it may include about 20-25% by weight of a low viscosity silicone oil and a high viscosity ester-based oil based on the total weight of the composition. When the low-viscosity silicone oil and high-viscosity ester-based oil are contained in an amount of more than about 25% by weight based on the total weight of the composition, the product surface is hardened and a caking phenomenon that does not cause a payoff occurs, and the resultant product is not powdery. There is a problem in that it becomes a paste and a general automatic tableting and filtering process is impossible. When the low-viscosity silicone oil and the high-viscosity ester-based oil are included in an amount of less than about 20% by weight based on the total weight of the composition, the moldability is very poor, and the formulation stability is poor.

In the above composition, the oil part may further include an oil commonly used in cosmetic compositions.

The composition includes a powder portion containing a pearl powder.

In the present specification, the "pearl powder" may include, without limitation, powders that can be used for the glossiness and pearliness of the cosmetic composition. For example, the pearl powder may include aluminum / silica, mica / titanium dioxide / iron oxide, or a combination thereof, but is not limited thereto.

In the above composition, about 45-60% by weight, about 50-55% by weight, or about 50% by weight of pearl powder based on the total weight of the cosmetic composition may be included, but is not limited thereto.

In the above composition, the powder part is a powder commonly used in cosmetic compositions, for example, sodium stearate, aluminum stearate, zinc stearate, calcium stearate, magnesium stearate (Magnesium stearate), aluminum distearate (Aluminum distearate) and magnesium myristate (Magnesium myristate) may further include one or more selected from the group consisting of.

In the composition, it may be formulated in a compressed powder form. By formulating the composition in compressed powder form, the payoff of the composition can be improved.

The cosmetic composition may further include a pigment. Specifically, the pigment is yellow 203, yellow 4, yellow 5, yellow 201, yellow 204, red 103, red 201, red 202, red 218, red 220, red 223, And pigments for coloring, such as organic pigments of barium or aluminum lakes, such as red 226, red 227, blue 1, and blue 2, and pearl pigments.

The pigment may be included in an amount of about 0.01% to about 10% by weight, about 0.1% to about 8% by weight, and about 1% to about 5% by weight based on the total weight of the cosmetic composition.

The cosmetic composition according to one embodiment also additional ingredients commonly used in cosmetics, such as dispersants, pigments, fragrances, fillers, preservatives, preservatives, neutralizing agents, sunscreens, sweeteners, vitamins, free-radical scavengers, metal ion containment Agents, pH adjusting agents, and any conventional cosmetic ingredients that can be selected from mixtures thereof.

One skilled in the art can select any additional ingredients and / or amounts thereof so that the advantageous properties of the compositions according to the present specification are not adversely or substantially unaffected by the expected addition.

The cosmetic composition according to one embodiment may be formulated for eye makeup, such as an eye shadow, but may also be formulated with a blusher or highlighter.

The cosmetic composition according to one aspect solves the problem of moldability and caking, which is a problem that occurs when a high-viscosity oil is used in a high content by mixing low-viscosity silicone oil and high-viscosity oil, so it can be formulated into a compressed powder form and adhered , Excellent spreadability and gloss.

Experimental Example  1. Evaluation of formability

Sensory evaluation was performed to evaluate the moldability of the cosmetic compositions according to Examples 1-2 and Comparative Examples 1-3. This is for examining the difference in moldability according to the blending ratio of the oil, Examples 1 and 2, and Comparative Example 1 is a ratio of diisostearyl malate and dimethicone of 2: 1, respectively 25%, 21% , 18% content, and Comparative Examples 2 and 3 were applied in a 24% content with the ratio of diisostearyl malate and dimethicone being 1: 1 and 1: 2, respectively.

The evaluation of moldability was evaluated according to whether or not the cosmetic material is removed from the mold when it falls, and whether powder is generated when the contents are taken. The slower the score, the lower the drop stability, and was evaluated to be powdery when the product was taken. Table 2 shows the evaluation results.

In Comparative Example 1, the state of the prepared bulk was relatively stable, but when the tableted contents were taken by hand or an applicator, there was powder dusting. In Comparative Example 2, the prepared bulk was uneven and there was a problem in that the content of the contents was dislodged from the fan and the fan was detached from the drop test after tableting. All are out. The prepared bulk state of Example 1 was produced rather tightly, but the contents were slightly leaked from the mold when filling, but this was not a problem. Also, when the molded contents were taken by hand or an applicator, there was almost no powder flying. In Example 2, the hardness was firmly measured as compared to Example 1, and there was a slight dustiness, but the drop test result appeared stable, and the contents did not leak out even during filling.

As a result, it was confirmed that the oil content and mixing ratio of Examples 1 and 2 were the most ideal.

Experimental Example  2. Glossiness , Spreadability , Adhesion, and durability evaluation

An experiment was conducted to check the difference in glossiness, spreadability, skin adhesion, and durability depending on the blending ratio of the oil.

Specifically, 10 females aged 20 to 30 were tested, and the sensory evaluation was performed using the evaluation items as glossiness, spreadability, adhesion, and durability, and the results are shown in Table 3.
