Description

{Cosmetic composition for eye make-up with excellent curling retentivity and longlash retentivity}

The present invention relates to an eye makeup cosmetic composition having excellent curling retention and long lash retention, and more specifically, a fibrous fiber and a silicone-grafted acrylate polymer together with a low specific gravity volatile oil and low specific gravity powder. It relates to an eye makeup cosmetic composition comprising

Functional characteristics required for eye makeup cosmetics used for eyelashes such as mascara include volume, curling power, and long lash power. And as the climate becomes hot and humid, there is a growing need for durability that can maintain the state of first makeup for a long time with light eyelash makeup expression, that is, curling retention power that maintains the curling degree of makeup eyelashes for a long time without sagging.

Also, due to the characteristics of eyelashes, Asian women's eyelashes are relatively short compared to Western women, so there is a clear preference for the long lash function. Recently, eyelash extensions are used to artificially lengthen short eyelashes, and mascara containing fibrous fibers is used to realize the effect of extension treatment. Due to the morphological nature of the fibrous fiber, it adheres to the eyelashes for a long time and has the advantage of providing an immediate long lash improvement effect. Along with the falling phenomenon, disadvantages such as a decrease in long lash holding power due to this occur. The reason that the powder fallout phenomenon is a problem is that foreign substances such as fibrous fibers may cause eye irritation if they enter the eye. In addition, due to the high temperature and humid climate, the durability of long-lashed eyelashes, that is, the curling power that maintains the curling degree of makeup eyelashes for a long time without sagging, and long-lash retention power that maintains the fibrous fibers attached to the eyelashes for a long time without dropping them. demand is increasing. Therefore, it is necessary to develop a composition with excellent durability that can maintain the first makeup state for a long time with light eyelash makeup expression as two techniques for maintaining the long lash power of the eyelashes are applied in combination with the technology for maintaining the curling power of the eyelashes.

Accordingly, in Korean Patent Application No. 10-2014-0080987, the present inventors have disclosed the weight of the composition as a whole so as to fundamentally prevent the problem that the curling shape formed by applying the eye makeup composition to eyelashes and eyebrows is not maintained over time in Korean Patent Application No. 10-2014-0080987 Provided is an eye makeup cosmetic composition having excellent curling power and formulation stability while lowering the The cosmetic composition contains no water or aqueous components at all, and contains a low specific gravity volatile oil and low specific gravity powder, so that the curling power formed when applied to hair such as eyelashes remains unchanged throughout the day. It was proved to have an improved effect compared to the eye makeup composition of

Based on the excellent curling power and formulation stability of the Korean Patent Application No. 10-2014-0080987, which is a prior application, the present inventors exhibited immediate long lash power by containing fibrous fibers, and there is no fall of fibrous fibers, so it is not only safe without irritation but also has long lash holding power As a result of diligent efforts to develop an excellent eye makeup cosmetic composition, the present invention has been completed.

It is an object of the present invention to include a low specific gravity volatile oil, a low specific gravity powder, a fibrous fiber, and a silicone-grafted acrylate polymer, thereby exhibiting excellent curling power and long lash power when applied to hair such as eyelashes. to provide a composition.

In order to achieve the above object, the present invention includes a low specific gravity volatile oil, a low specific gravity powder, a fibrous fiber, and a silicone-grafted acrylate polymer, and uses pure water at 4° C. as a standard material. When set to 1, the specific gravity of the low specific gravity volatile oil and the low specific gravity powder is less than 1, respectively, to provide an eye makeup cosmetic composition.

The eye makeup cosmetic composition according to the present invention has a very low specific gravity and does not have a feeling of weight when applied to hair such as eyelashes, so that the curling power of the first makeup hair can be maintained without change throughout the day. speed can be achieved.

In addition, since it contains a silicone-grafted acrylate polymer together with the fibrous fiber, the fibrous fiber is attached at the time of first application, so that the elongated eyelashes do not fall off over time. this can be maintained.

As used herein, the term "hair" refers to a thread-like structure composed of keratinized epithelial cells and containing keratin that comes out of the skin surface, and refers to the skin area where the hair grows, the shape and function of the hair. Regardless, it is the broadest concept that includes eyelashes, eyebrows, and hair.

As used herein, the term "long lash force" refers to an effect in which eyelashes are produced longer than their original state, and "curling force" refers to an effect in which the eyelashes are raised at an increased angle compared to their original state.

Hereinafter, the present invention will be described in more detail.

The present invention is an eye makeup cosmetic composition comprising a low specific gravity volatile oil and a low specific gravity powder, and when pure water at 4° C. as a standard material has a specific gravity of 1, the specific gravity of the low specific gravity volatile oil and the low specific gravity powder is less than 1, respectively. it's about The composition may be a non-aqueous composition that does not include water or an aqueous component, and the specific gravity of the composition including the low specific gravity volatile oil and the low specific gravity powder may be less than 1, more specifically, 0.001 or more and less than 1.

The specific gravity is a ratio between the mass of a certain material and the mass of a standard material having the same volume, and in the case of a liquid, pure water at 4° C. as a standard material has a specific gravity of 1. Therefore, when the specific gravity is less than 1, it means that the weight is lighter when compared to the same volume of water, and the smaller the value, the lighter it is.

By oil is meant a non-aqueous fatty substance that is liquid at 25° C. and atmospheric pressure (760 mmHg), usually expressed at room temperature. The low specific gravity oil of the present invention means an oil having a specific gravity of less than 1. The low specific gravity of the low specific gravity oil is preferably 0.001 or more and less than 1, more preferably 0.1 or more and less than 1, for example. In addition, the oil can be divided into a volatile oil and a non-volatile oil, and the volatile oil means an oil that can evaporate within 1 hour at room temperature and atmospheric pressure when in contact with skin or keratin fibers.

The low specific gravity volatile oil of the present invention may include at least one selected from the group consisting of a low specific gravity volatile hydrocarbon oil and a low specific gravity volatile silicone oil. The hydrocarbon oil is an oil containing hydrogen and carbon atoms, and may be, for example, a hydrocarbon oil having 8 to 16 carbon atoms. More specifically, the low specific gravity volatile hydrocarbon oil may be a branched alkane having 8 to 16 carbon atoms, an ester, or a mixture thereof, and the alkane is an isoalkane having 8 to 16 carbon atoms, also known as isoparaffin, and isodecane. , isododecane, isohexadecane, and the like. The volatile silicone oil is a volatile linear or cyclic silicone oil, and may include, for example, a silicone oil having a viscosity of 6 centistokes or less at 25° C. and in particular having 2 to 5 silicon atoms. More specifically, the low specific gravity volatile silicone oil may include dimethicone, trisiloxane, cyclopentasiloxane, or a mixture thereof.

The composition of the present invention may contain 1 to 80% by weight of the low specific gravity volatile oil based on the total weight of the composition, preferably 30 to 50% by weight. If the content of the low specific gravity volatile oil is less than 1% by weight, the amount of solvent capable of dispersing the solids is too small, so it is difficult to make a creamy formulation suitable for use on eyelashes, and it is difficult to obtain a low specific gravity composition, 80 weight If the % is exceeded, there is a problem in that the volatilization becomes too fast, making it difficult to prepare and store the composition.

The low specific gravity powder of the present invention means a powder having a specific gravity of less than 1. The low specific gravity of the low specific gravity powder is preferably 0.001 or more and less than 1, more preferably 0.1 or more and less than 1, for example. If the specific gravity of the powder is 1 or more, there is a problem in that the weight of the composition containing the powder is not only felt when attached to the eyelashes, but also the curling power decreases over time due to the weight. The low specific gravity powder is, for example, talc, sericite, mica, calcium carbonate, magnesium carbonate, kaolin, boron nitride, titanium oxide, zinc oxide, iron oxide, carbon black, cerium oxide, zirconium oxide, silica, nylon and polymethyl meta. It may include one or more selected from the group consisting of acrylates.

The particle shape of the low specific gravity powder of the present invention may be, for example, a spherical shape, a plate shape, or a needle shape, but is not limited thereto. It may also have a porous or hollow shape with many voids rather than a solid shape. The average particle diameter of the powder is also not particularly limited, but may be 20 μm or less, more specifically 0.1 μm or more and 20 μm or less.

The composition of the present invention may include the low specific gravity powder in an amount of 0.1 to 20% by weight, preferably 1 to 10% by weight, based on the total weight of the composition. When the content of the low specific gravity powder is less than 0.1% by weight, the low specific gravity effect of the composition does not appear, and when it exceeds 20% by weight, the viscosity of the composition increases, and when applied to the eyelashes, the composition forms agglomerates and agglomerates the makeup state of the eyelashes. There is a problem that is not clean.

The fibrous fiber of the present invention may be any type of fiber having a length of 0.1 mm or more. For example, selected from the group consisting of vinylidene, cotton, hemp, polynosic, rayon, polyvinyl chloride, polyester, silk, wool, acetate, vinylon, polyurethane, acrylic, nylon, polyethylene, polypropylene, cellulose, etc. It may include one or more types. More specifically, since the composition of the present invention does not contain water or an aqueous component, the high hydrophilicity of the rayon material and the cellulose fiber has low stability in the formulation, and the low hydrophilicity of the nylon material, polyethylene material, and polypropylene material The dispersion stability in the fiber formulation is particularly good.

Most of the shape of the fibrous fiber of the present invention is a long thread shape, but is not limited thereto. It may also be a porous or hollow shape with many voids rather than a solid shape. In addition, the average diameter of the average eyelashes of Asians is about 71.8±22.5 μm, and the diameter of the fibrous fiber to be most naturally attached to the eyelashes may be preferably 5 to 70 μm, and more preferably 10 to 30 μm. . If the diameter of the fibrous fiber is less than 5 μm, the effect of improving adhesion cannot be expected because it is too thin compared to the diameter of the eyelashes. It is undesirable because it is clumped and unnaturally produced.

The length of the fibrous fiber of the present invention is not particularly limited, but may be 1 mm or more, preferably 1 mm or more and 10 mm or less. If the length of the fibrous fiber is less than 0.1 mm, it is not suitable because the composition including the fibrous fiber cannot provide instant long lash force when attached to the eyelashes. However, if the length of the eyelashes is 0.1 mm or more, the central part of the eye is long and the eyelashes are shorter toward the head and the tail of the eye. In this case, the mixing ratio of the long fibrous fiber and the short fibrous fiber is preferably 1:1 to 1:6. If the ratio of the long fibrous fiber to the short fibrous fiber is less than 1:1, the length of the eyelashes will not grow evenly, resulting in an unnatural appearance. If it exceeds 1:6, the effect of increasing the length of the eyelashes is not There is a problem that it is difficult to show as natural eyelashes because it is thick and lumpy and has a rough finish.

The composition of the present invention may include the fibrous fiber in an amount of 0.1 to 10% by weight, preferably 0.5 to 5% by weight, based on the total weight of the composition. When the content of the fibrous fiber is less than 0.1% by weight, the long lash effect does not appear at all, and when it exceeds 10% by weight, the viscosity of the composition increases, and when applied to the eyelashes, the composition forms agglomerates and the makeup state of the eyelashes is clean. There is a problem that it doesn't.

In the present invention, a silicone-grafted acrylate polymer is included as a film-forming polymer in order to prevent the fibrous fiber from falling off. The composition of the present invention is a composition with a low specific gravity that does not contain water or an aqueous component, and forms a thin and flexible continuous film by a lipophilic polymer. In general, the film film is hard and brittle compared to silicone polymers, which are silicone-acrylate. Polymer (silicone-grafted acrylate polymer) has the advantage of improving the adhesion of fibrous fibers because the film film is not easily broken by external stimuli due to its flexible characteristics.

The silicone-grafted acrylate polymer of the present invention has various types depending on its composition, and in the present invention, isobutyl methacrylate / bis-hydroxypropyl dimethicone in consideration of the thickness and formulation stability of the film film acrylate copolymer, acrylate/dimethicone copolymer, acrylate/behenylacrylate/dimethicone methacrylate copolymer, acrylate/polytrimethylsiloxymethacrylate copolymer, acrylate/bis-hydroxypropyl Dimethicone cross polymer, acrylate/dimethicone copolymer, acrylate/dimethicone methacrylate/ethylhexyl acrylate copolymer, acrylate/propyltrimethicone methacrylate copolymer, acrylate/ethylhexyl acrylate/ At least one selected from the group consisting of dimethicone methacrylate copolymer, acrylate/stearyl acrylate/dimethicone methacrylate copolymer, and the like may be used in combination. The silicone-grafted acrylate polymer may be used by purchasing a commercially available product, but is not limited thereto.

The composition of the present invention may include the silicone-grafted acrylate polymer in an amount of 1 to 50% by weight, preferably 5 to 30% by weight, based on the total weight of the composition. If the content of the silicone-grafted acrylate polymer is less than 1% by weight, a continuous film film is not formed, so that the fibrous fiber is severely detached and the long lash effect is not maintained, and when it exceeds 50% by weight, the composition There is a problem in that it is difficult to apply in a desired state, such as the viscosity rises and the drying speed of the eyelashes is too fast, and partly starts to dry during application to the eyelashes.

The composition of the present invention may further comprise a dispersing agent. Since the composition of the present invention does not contain water and aqueous components as well as surfactant components, by further including a dispersant, the low specific gravity powder is evenly dispersed in the low specific gravity volatile oil and the agglomeration of the composition is prevented, thereby improving formulation stability. have. The dispersant may include at least one selected from polyhydroxystearic acid, lecithin, ethylhexyl palmitate, isopropyl palmitate, isostearic acid, and polyglyceryl-3 polyricinoleate.

The composition of the present invention may contain the dispersant in an amount of 1 to 60% by weight, preferably 3 to 30% by weight, based on the total weight of the low specific gravity powder and the fibrous fiber. If the content of the dispersant is less than 1% by weight, the dispersion effect of the powder and fibrous fibers is almost nonexistent, so that the powder and fiber sedimentation occurs over time and the formulation becomes unstable. It does not appear and the efficiency is reduced.

The eye makeup cosmetic composition of the present invention may further include a wax, a thickener, a preservative, a plasticizer, etc. within a range that does not impair the purpose and effect of the present invention in addition to the above components.

The eye makeup cosmetic composition of the present invention contains, in addition to the active ingredients, waxes, oils, powders, thickeners, pigments, nutrients, volatile solubilizers, antioxidants, preservatives and fragrances within the range that does not impair the effects of the present invention. Ingredients contained in the eye makeup composition (hereinafter referred to as "other ingredients") may be included.

In addition, the eye makeup cosmetic composition of the present invention may be included in a formulation including mascara, eye shadow, eyebrow pencil and eyeliner, and specifically may be for mascara, but is not limited thereto. According to another embodiment, the composition of the present invention may be applied not only to the eye makeup composition, but also to a formulation for, for example, hair styling.

Hereinafter, the present invention will be described in more detail through examples. These examples are only for illustrating the present invention, and it will be apparent to those of ordinary skill in the art that the scope of the present invention is not to be construed as being limited by these examples. Accordingly, the substantial scope of the present invention will be defined by the appended claims and their equivalents.

[Test Example 1] Usability test (sensory evaluation)

To actually use the mascara products of Comparative Examples 1 to 4 prepared by the conventional method and the mascara products of Examples 1 to 3 prepared by the method of the present invention on a daily or frequent basis for 30 women aged 20 to 40 years. After that, the effects of the products were compared. The test items were curling force, curling holding power, drying speed, no clumping, long lash power and long lash holding power. After evaluating each item, a score of 0 to 15 was given to give the average score. In order to ensure the accuracy of the data, each was repeated 5 times, and the results are shown in Table 2 below. If the average score was less than 4.0, "×", 4.0 to 8.0, "△", 8.1 to 12.0, "○", and more than 12.0, "◎".

As can be seen from Table 2, Comparative Examples 1 and 2, which are conventional mascara compositions containing water and aqueous components, Comparative Examples 3 to 4, which do not contain water and aqueous components, and Examples 1 to 3, which are compositions of the present invention It was confirmed that the satisfaction with curling holding power and drying speed was low compared to the above. This is because the specific gravity of the formulation containing water and aqueous components must be similar to or higher than that of water, so that the eyelashes feel heavy and curling is inevitable. In addition, Comparative Example 3, which does not contain water and aqueous components, but contains a low specific gravity nonvolatile oil and a low specific gravity powder, slightly improved the curling retention power compared to Comparative Examples 1 and 2, but the drying speed was due to the wetness of the nonvolatile oil. Satisfaction level was found to be the lowest.

On the other hand, Examples 1 to 3, which simultaneously contained a nylon fiber and a film former together with a low specific gravity volatile oil and a low specific gravity powder, showed very improved satisfaction with curling retention and long lash retention compared to Comparative Examples, which are conventional compositions. was shown.

Regarding the no-agglomeration item, Comparative Examples 3 and 1 not containing a surfactant and a separate dispersing agent are Comparative Examples 1 and 2 containing a surfactant and Comparative Examples 4 and 2 containing a separate dispersing agent Compared to ~3, it was confirmed that the satisfaction with the absence of agglomeration was lower.

[Test Example 2] Specific gravity measurement

The specific gravity data of the mascara prepared from the compositions according to Comparative Examples 1 to 4 and Examples 1 to 3 were measured by the following method.

<Specific gravity measurement method>

1) Prepare a 50ml specific gravity cup and measure the weight of the specific gravity cup.

2) Fill the specific gravity cup with water and measure the weight.

3) Obtain the weight of water by subtracting the weight of the specific gravity cup in 1) from the weight of the specific gravity cup + water in 2).

4) Measure the weight by filling each composition in the specific gravity cup of 1) above.

5) The weight of the composition is obtained by subtracting the weight of the specific gravity cup of 1) from the weight of the specific gravity cup + composition in 4).

6) Calculate the specific gravity of the composition by dividing the weight of the composition by the weight of water.

It was repeated three times for each composition to obtain an average value, and the results are shown in Table 3 below.

Test Items Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Example 1 Example 2 Example 3 importance 1.15 1.07 1.06 0.84 0.84 0.92 0.93

As can be seen from Table 3, it was confirmed that Examples 1 to 3 of the present invention had a specific gravity of less than 1 compared to Comparative Examples 1 to 4, which is a conventional mascara composition, and had a low specific gravity. This is because the composition of the present invention does not contain water and aqueous components, and the specific gravity of the composition is lowered by simultaneously including a low specific gravity volatile oil and a low specific gravity powder. By realizing lightness through this, the degree of curling does not decrease when applied to eyelashes and the like, and it affects the curling holding power that is maintained as it is.

[Test Example 3] Dispersibility test

The dispersibility of the mascara prepared from the compositions according to Comparative Examples 1 to 4 and Examples 1 to 3 was measured by the following method. The height of the separated liquid phase was measured by separating the liquid and solid phase components using a centrifuge. In this case, the higher the height of the separated liquid phase, the lower the stability of the formulation.

<Method of measuring dispersibility>

1) Put 15 g of each composition in the same tube in a centrifuge and mount it.

2) Operate the centrifuge at 1000 rpm for 5 minutes.

3) Take out the tube and measure the height of the separated liquid phase.

It was repeated three times for each composition to obtain an average value, and the results are shown in Table 4 below.

Test Items Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Example 1 Example 2 Example 3 Layer separation height (mm) 11.0 11.0 25.0 14.0 19.5 11.0 10.0

As can be seen from Table 4 above, Comparative Examples 1 and 2, which are conventional compositions, contain a surfactant component to make an oil-in-water emulsion formulation together with water and aqueous components, so this surfactant component also contains powder and fibrous fibers. It was confirmed that it was a stable formulation with a low separation height by a centrifugal separator by acting as a dispersant, but Comparative Examples 3 and 1 that did not contain a separate dispersing agent showed that the oil was separated very much by a centrifuge. . This is because the separation of oil, powder, and fibrous fibers in the formulation progressed over time, thereby degrading the stability of the formulation.

In contrast, in Examples 2 to 3, which are the compositions of the present invention, the separation height by a centrifuge was low due to the inclusion of the dispersant, and thus it was confirmed that the formulation stability was excellent.

[Test Example 4] Measurement of drying time

The time until complete drying of the mascara prepared from the compositions according to Comparative Examples 1 to 4 and Examples 1 to 3 was measured by the following method. The longer the complete drying time, the slower the drying speed.

<Measuring method of drying time>

1) Each composition is equally applied to a glass plate with a thickness of 100 μm using an applicator.

2) Using a filter paper, take a picture of the coated surface at intervals of 1 minute.

3) Measure the time when the contents are no longer printed on the filter paper.

It was repeated three times for each composition to obtain an average value, and the results are shown in Table 5 below.

Test Items Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Example 1 Example 2 Example 3 Complete drying time (min) 8.5 8.2 10.5 6.1 6.0 5.8 5.8

As can be seen from Table 5, the drying rates of Comparative Examples 1 and 2 containing water and aqueous phase components and Comparative Example 3 containing non-volatile oil are Comparative Examples 4 and 1 and 1 of the present invention containing volatile oil. It can be seen that it is very late compared to 3. It can be seen that the embodiment of the present invention is convenient to use because a fast drying speed is very important due to the characteristics of the mascara.

[Test Example 5] Measurement of curl retention force

The curling retention power of the mascara prepared from the compositions according to Comparative Examples 1 to 4 and Examples 1 to 3 was measured by the following method. The change in the curling angle over time was measured using a digital camera, and the smaller the change in the curling angle, the better the curling retention power.

<Measuring method of curling holding force>

1) Attach artificial eyelashes to a semi-circular acrylic rod.

2) Fix the position of the digital camera so that the side of the artificial eyelashes can be photographed.

3) Apply each composition equally to the artificial eyelashes 12 times.

4) Measure the eyelash curling angle immediately after application with a digital camera.

5) Repeatedly measure the eyelash curling angle with a digital camera every 6 hours.

For each composition of Comparative Examples 1 to 4 and Examples 1 to 3, it was repeated 3 times to obtain an average value, and the results are shown in Table 6 below.

Test Items Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Example 1 Example 2 Example 3 Curling angle immediately after application (°) 38.5 38.0 38.2 38.4 38.0 38.5 38.5 Curling angle after 6 hours (°) 22.2 20.0 22.5 21.0 36.0 37.0 37.5 Curling angle after 12 hours (°) 15.5 15.2 20.5 20.5 32.0 36.1 36.0

As can be seen from Table 6, unlike the conventional mascara compositions Comparative Examples 1 to 4, in which the curling angle rapidly decreased with the lapse of time, Examples 1 to 3 of the present invention showed the curling angle immediately after application and the curling angle after 12 hours. There was almost no difference, and it was confirmed that the curling retention was very good. This is because the composition of the present invention not only does not contain water and aqueous components, but also contains a low specific gravity volatile oil and a low specific gravity powder at the same time, so the specific gravity of the composition is low, and the weight on the eyelashes is small, and the eyelashes are This is because there is less sagging.

[Test Example 6] No powder fallout (long lash retention force) measurement

The absence of powder fall (long lash retention) of the mascara prepared with the compositions according to Comparative Examples 1 to 4 and Examples 1 to 3 was measured by the following method.

<No powder fall off (Long lash holding force) measurement method>

1) Apply each composition to a glass plate in the same thickness using an applicator, and then dry completely.

2) Use a cross cutter of artificial eyelashes to make a grid pattern on the glass plate.
