Description

Solid Eye Make-up Cosmetic Composition {Solid Eye Make-up Cosmetic Composition}

The present invention relates to an eye makeup cosmetic composition.

Eye-makeup cosmetics include, for example, shadow, mascara, liner, and the like.

Among them, the liner is used on the mucous membrane around the eyes, the double eyelid line, or the eyelids to make the eyes look clear and large. Eyeline refers to a line drawn along the edge of the eye to make the eyes look larger during makeup. Each individual has a different thickness and length of the eyeline, which is an element that greatly influences a person's impression depending on the shape of the eyeline along with the eyes. is considered one of the For example, if the eyes do not have double eyelids or the outer corners of the eyes are short, the eyes may look small, so the shape is changed by drawing an eye line.

In general, conditions required for an eyeliner makeup composition include uniform application without color development, powdering or spreading, and long-lasting durability without being easily spread by sweat and oil.

On the other hand, conventional eyeliner makeup compositions are classified into pencil type, liquid type, etc. according to the formulation. Among them, the pencil type is characterized by easy carrying and use and waterproof function, but has a disadvantage that delicate makeup is difficult because it is a stick type in terms of formulation characteristics. In addition, while the liquid type can provide a thin and delicate eyeline makeup effect, it has a problem in that it gives an artificial and unnatural feeling with a glossy shine. Therefore, this liquid type composition compensated for the disadvantages by minimizing the gloss by preparing a matte product, but it also had a limitation that it was not as natural as the pencil type.

In order to solve the above-mentioned problems, an object of the present invention is to show a strong durability against both oil and moisture compared to conventional solid eye makeup cosmetic compositions, and to provide a glossiness.

The present invention provides a solid eye makeup cosmetic composition. Specifically, the present invention includes an oil phase, a pigment, and a film-forming agent, wherein the film-forming agent includes Hydrogenated Styrene / Methyl Styrene / Indene Copolymer , A solid eye makeup solid cosmetic composition is provided.

In the cosmetic composition of the present invention, hydrogenated styrene / methyl styrene / indene copolymer is characterized in that it is included in 10 to 30% by weight based on the total weight of the composition.

In the cosmetic composition of the present invention, the oil phase part is characterized in that it includes wax and volatile silicone oil.

In the cosmetic composition of the present invention, the wax is characterized in that it includes polyethylene and ceresin.

In addition, the cosmetic composition of the present invention may be prepared for a stick-type eyebrow, stick-type eyeliner, stick-type eye shadow, stick-type lip liner, or stick-type lip crayon.

The eye make-up cosmetic composition according to the present invention can provide both waterproof and oil-proof effects by forming a film film while a water-resistant film component is applied to the eye line, and has a long-lasting effect that is not erased. In addition, it is characterized in that the film film forms a slight gloss, providing an effect in which the eye line is clearly visible after eye line makeup.

Hereinafter, the present invention will be described in detail so that those skilled in the art can easily practice it with reference to the accompanying technology. However, it will be apparent to those skilled in the art that the present invention can be implemented in many different forms and is not limited to the embodiments described below.

The present invention is a solid eye makeup cosmetic composition, which exhibits uniform application without color development, powdering, or smearing, and long-lasting durability without being easily spread by sweat and oil, while providing a waterproof effect while providing a waterproof effect. Unlike, it is characterized by minimizing the stiff feeling after application.

Film-former means an agent capable of forming a film when applied to keratin materials and providing the composition with properties arising from cohesiveness and/or tackiness, the present invention includes oily parts, pigments, and film-formers. and a solid eye makeup cosmetic composition containing hydrogenated styrene/methyl styrene/indene copolymer as a film forming agent.

As a specific embodiment, the hydrogenated styrene / methyl styrene / indene copolymer may be included in an amount of 10 to 30% by weight based on the total weight of the composition. When the hydrogenated styrene / methyl styrene / indene copolymer is included in an amount of less than 10% by weight, the effect of the waterproof function that is not erased by water may be insignificant. In addition, when the content exceeds 30% by weight, the viscosity increases, so that it may not be molded into a desired solid formulation, and specifically, it may not be possible to form a stick formulation.

The present invention is also characterized in that it does not contain a trimethylsiloxysilicate component. The trimethylsiloxysilicate component forms a thick film after application and is strong in water resistance, but there is a problem that a stiff feeling occurs after application of the film, but the present invention is characterized in that there is no such inconvenience.

As a specific embodiment, the eye makeup solid cosmetic composition of the present invention may include wax and volatile silicone oil in the oily part.

The wax component may be included to form hardness in a solid form, particularly in a stick formulation. The wax may be at least one selected from the group consisting of polyethylene, ceresin, synthetic wax, ozokerite, candelilla wax, carnauba wax, beeswax, paraffin and microcrystalline wax, preferably polyethylene and ceresin. this can be used Polyethylene helps maintain the shape of a thin core and improves hardness of pencil formulations, and Ceresin can improve the easily breakable phenomenon by giving elasticity to fragile pencil formulations. desirable for The wax may be included in 10 to 20% by weight based on the total weight of the cosmetic composition of the present invention according to one embodiment, and may have a desirable hardness to be used as a stick formulation in the above range. If the wax is used in less than 10% by weight, hardness may not be formed and may be crushed, and if it is used in excess of 20% by weight, the hardness may increase and may not be suitable due to skin irritation during makeup.

When the volatile silicone oil is used as a film forming agent, it is volatilized after being applied to the skin to help form a film film. In addition, it is suitable to use a volatile silicone oil having a VISCOSITY value of 8 or less at room temperature to impart soft application to the cosmetic composition or to serve as a solvent. The volatile silicone is caprylylmethicone, cyclomethicone, cyclotetrasiloxane, cyclohexasiloxane, cycloheptasiloxane, decamethylcyclopentasiloxane, cyclotetrasiloxane, cyclotrisiloxane, dimethicone, capryl Dimethicone, Caprylyltrimethicone, Cetearylmethicone, Hexadecylmethicone, Hexylmethicone, Laurylmethicone, Myristylmethicone, Phenylmethicone, Stearylmethicone, Stearyldimethicone, Trifluoro Ropropylmethicone, cetyldimethicone, polyphenylmethylsiloxane, dimethylpolysiloxane, methylphenylpolysiloxane, methylctrimethicone, diphenylsiloxyphenyltrimethicone, phenyltrimethicone, isododecane, and isohexane It may be one or more selected from decane, but is not limited thereto. The volatile silicone oil may be included by about 10 to 30% by weight based on the total weight of the cosmetic composition. If the content of the silicone oil is out of the above range, the hardness of the cosmetic composition is not suitable for application to the skin, and thus the application properties may be reduced.

As a specific embodiment, the pigment included in the solid eye makeup cosmetic composition of the present invention may be at least one selected from the group consisting of inorganic pigments and organic pigments, of which black iron oxide is more preferably used. The pigment plays a role in color development during makeup, and may be included in an amount of 10 to 40% by weight based on the total weight of the cosmetic composition. In addition, it is more preferable because it can have a feeling of use, spreadability, and melt viscosity desirable for use in a stick formulation in the above content. When the pigment is used in an amount of less than 10% by weight, the color is light when the skin is colored, and the makeup effect is reduced.

The cosmetic composition of the present invention may further include thickeners, preservatives, plasticizers, etc. within the range that does not impair the object and effect of the present invention in addition to the above components, and other nutrients, volatile solubilizers, antioxidants, preservatives and fragrances, etc. Ingredients (hereinafter referred to as "other ingredients") contained in the same conventional makeup composition may be included.

The solid cosmetic composition for eye makeup of the present invention is preferably prepared in a stick formulation, but is not limited thereto.

As a specific example, the cosmetic composition of the present invention may be prepared for a stick-type eyebrow, stick-type eyeliner, stick-type eye shadow, stick-type lip liner, or stick-type lip crayon, and in particular, may have a stick-type eyeliner formulation. , but is not limited thereto.

Hereinafter, the present invention will be described in more detail through examples. However, these examples are intended to illustrate the present invention by way of example, and the scope of the present invention is not limited to these examples.

[Example]

1. Preparation of solid eye makeup cosmetic composition (Examples 1-3 and Comparative Examples 1-3)

An eyeliner cosmetic composition comprising the composition (unit: weight%) of Table 1 below was prepared.

After weighing each component of Table 1 in a beaker according to the content, the hydrogenated styrene / methyl styrene / indene copolymer and polyethylene, ceresin, synthetic wax, and candelilla wax were heated to 90 ° C., and an Aji mixer ( AGI mixer) for 15 minutes at 1000 rpm. Separately, the pigment was put into a food mixer and dispersed three times for 20 seconds. After mixing all of the mixtures respectively mixed as described above and heating to 85 ° C., the other raw materials were heated to 85 ° C. and heated and mixed at 2000 rpm for 15 minutes with an AGI mixer to prepare a cosmetic composition.

2. Formability evaluation according to hydrogenated styrene / methyl styrene / indene copolymer content

1 shows the fact that the compositions of Example 1 (a) and Comparative Example 1 (b) were completed. The cosmetic composition thus prepared was molded using molding. 2(a) shows the composition of Example 1 in the upper and lower moldings, and FIGS. 2(b) and 2(c) show pictures of the composition of Comparative Example 1 in the upper and lower moldings. was

In order to evaluate moldability according to the content of hydrogenated styrene/methylstyrene/indene copolymer, Example 1 and Comparative Example 1 were prepared in stick form and compared. As shown in Figure 3, when the hydrogenated styrene / methyl styrene / indene copolymer content is less than 30% by weight (Experimental Example 1), the composition could be molded into a stick formulation. However, as can be seen from FIGS. 2(b) and 2(c), when the hydrogenated styrene/methylstyrene/indene copolymer content exceeds 30% by weight (Comparative Example 1), the melt viscosity is high. It could not be molded into a stick formulation.

Therefore, in order to prepare a composition that can be formulated in a specific form such as a stick formulation with excellent moldability, it is confirmed that the content of hydrogenated styrene / methyl styrene / indene copolymer is preferably included at 30% by weight or less. did

3. Sensory evaluation of eyeliner composition

An eyeliner was prepared using the composition of Example 1, and the results of confirming its waterproof and oil-proof functions are shown in FIG. 3 .

After taking a picture of applying the eyeliner of Example 1 to 3 pieces of artificial leather and stirring it for 20 minutes in a state where the artificial leather is submerged, the picture is taken, and the L value of the two taken pictures is analyzed to determine whether it is waterproof. did When the L value of artificial leather is analyzed and the L value of all 10 pieces is 50% or more, it is judged to have water resistance. As a result of testing waterproof and oil proof, respectively, as can be seen in FIG. 3, it was confirmed that all three artificial leathers were maintained at 50% or more, confirming that they had both waterproof and oil proof effects.

Figure 4 shows the L value for color durability immediately after application, 4 hours, and 8 hours after application of the eyeliner of Example 1. To evaluate color durability, color durability (%) was derived by taking pictures of the test area (eyebrows) after using the product, comparing them with pictures taken 4 hours and 8 hours later, and analyzing the L value for each hour. The L value indicates the degree of brightness of a color, and the higher the L value, the brighter it is. As confirmed in Figure 4, the eyeline durability was evaluated to be excellent.
