Description

Powder type eye makeup cosmetic composition {Powder type cosmetic composition for eye make-up}

The present invention relates to a powdery eye makeup cosmetic composition.

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

In order to manufacture a conventional eye shadow having excellent glossiness, it was intended to develop a powdered eye makeup product containing a high content of pearl powder and oil.

However, when the excess oil is included, the powder in the composition is agglomerated like a spherical or dough rather than powdery, and thus the moldability is very low. Thus, the amount of oil used to make a compacted powder eye makeup product has been limited to a certain level. In addition, when the oil is excessively included in the composition, the surface is hard after compression, and thus a caking phenomenon occurs in which no powder can be taken.

Therefore, it is necessary to develop a compact powder eye makeup cosmetic composition containing a large amount of pearl powder and oil, but having excellent glossiness, but excellent moldability, applicability, and adhesion.

One aspect is that the eye makeup cosmetics having excellent moldability, spreadability, glossiness, and spreadability can be formulated in compressed powder form by containing a large amount of pearl powder by containing an excess of two or more oils including low viscosity silicone oil and high viscosity oil. It provides a composition and a method for producing the cosmetic composition.

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

Cosmetic composition according to one embodiment may be a composition having excellent moldability, which can be formulated in a compressed powder form while containing an excess of oil and a pearl powder having a high refractive index. In general, in order to maximize glossiness and to improve the adhesion of the powder to the skin, the eye makeup product uses high refractive index and high viscosity oil. However, when the oil having high refractive index and viscosity is excessively contained in the composition, there is a problem in that the moldability is lowered, and the surface is hard after compression, and a caking phenomenon that is difficult to take powder occurs, resulting in a problem in that the payoff is reduced. However, the cosmetic composition according to one aspect can be produced in a compacted powder form by including the low viscosity silicone oil and high viscosity oil in the oil portion in a desirable ratio, while being excellent in the application properties, glossiness, and adhesion, while being useful in eye makeup products. Can be used.

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

As used herein, "low viscosity silicone oil" is not limited to any silicone oil generally used in cosmetic compositions, but may include dimethicone or cyclomethicone.

The low viscosity silicone oil may have a kinematic viscosity of 10 cSt to 50 cSt. Low viscosity silicone oils have the effect of inhibiting agglomeration of powdery phase, and this effect is stronger when the oil viscosity is lower. Since the silicone oil has a low viscosity, it is possible to improve the agglomeration of the powdery phase including a high content of the pearl powder to have excellent applicability.

The low viscosity silicone oil may be nonvolatile. When the kinematic viscosity of the low-viscosity silicone oil is 5 cSt or less, the volatility becomes high, so that it evaporates during the preparation of the cosmetic, it is preferable to use a non-volatile low-viscosity silicone oil.

In general, silicone oil and high viscosity ester-based oils are poor in compatibility, there is a problem that when the composition is mixed to the skin when applied to the skin does not adhere to the skin breaks. However, the low viscosity silicone oil contained in the cosmetic composition according to one aspect is characterized by excellent compatibility at room temperature with some high viscosity ester oil.

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

The high viscosity ester oil may have a viscosity of 1500 mPa · s to 3000 mPa · s. The high viscosity ester oil has a high viscosity and a high refractive index is used to maximize the glossiness of the eye makeup cosmetic composition and to improve the adhesion between the skin and the powder, adhesion, but when the high viscosity oil is contained in the composition in the form of compressed powder Since the caking phenomenon occurs on the surface after the conversion, there is a problem that the payoff is significantly reduced, which is difficult to be included in a high content. However, the composition according to an aspect includes a high viscosity ester-based oil and a low viscosity silicone oil together to include a high content of high viscosity oil, but does not generate a caking phenomenon and has excellent glossiness.

In the composition, the low viscosity silicone oil: high viscosity ester 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 high-viscosity ester-based oil in the ratio, it is possible to formulate into a compressed powder by eliminating the aggregation phenomenon, which is the limit of high-viscosity oils, while maintaining the powder bonding strength of the high-viscosity ester-based oil. When the ratio is out of the range, when taking the cosmetic composition may be severe fly off, the swelling phenomenon occurs by an external impact, or may be a problem of leaving in the container containing the composition.

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

In the composition, the oil portion may further include an oil that is commonly used in cosmetic compositions.

The composition comprises a powder portion comprising a pearl powder.

In the present specification, "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 composition, it may include, but is not limited to, about 45-60% by weight, about 50-55% by weight, or about 50% by weight of pearl powder relative to the total weight of the cosmetic composition.

In the composition, the powder portion is usually used in cosmetic compositions, for example sodium stearate, aluminum stearate, zinc 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 into a compressed powder. By formulating the composition into a compressed powder, 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, Pigments for coloring such as organic pigments and pearl pigments of barium or aluminum lakes such as red 226, red 227, blue 1 and blue 2 can be included.

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

Cosmetic compositions according to one embodiment also contain additional ingredients commonly used in cosmetics such as dispersants, pigments, flavorings, fillers, preservatives, preservatives, neutralizing agents, sunscreens, sweeteners, vitamins, free-radical scavengers, metal ion containment And any conventional cosmetic ingredients that may be selected from agents, pH adjusters, and mixtures thereof.

Those skilled in the art can select any additional ingredients and / or amounts thereof such that the advantageous properties of the compositions according to the present disclosure are not adversely affected or substantially affected by the expected addition.

Cosmetic compositions according to one embodiment may be formulated for eye makeup, such as eyeshadow, 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 caused by the use of a high viscosity oil by mixing a low viscosity silicone oil and a high viscosity oil in a desired ratio, it can be formulated into a compressed powder form and adhesion Excellent applicability, glossiness.
