Description

Makeup composition that is stable to temperature changes {MAKEUP COMPOSITION WITH STABILITY AGAINST CHANGE OF TEMPERATURE}

The present invention relates to a makeup composition that maintains stability even when there is a temperature change such as heating and cooling in one aspect.

Mascara (mascara) is a kind of cosmetics used by women, it is used to make up various colors of mascara liquid on the eyelashes to make the eyes stand out. The function of the general mascara is that relatively short lashes are relatively short and poorly struck, and women with small eyes want to express their eyes darker and more clearly by putting on mascara makeup. In particular, since the eyelashes of Asian women are shorter and poorer than Western women, it can be said that the desire to obtain effects such as volume, curling, and long lash using mascara is large.

The mascara consists of a container in which the mascara composition (liquid) is stored, a handle for opening and closing the container, a bar-shaped brush stand protruding below the handle, and an applicator formed at a lower end of the brush stand, wherein the handle By applying or separating the container with the mascara composition, the applicator is used.

Recently, mascara having a heating function was introduced to facilitate the use of mascara, more effectively apply the mascara composition to the eyelashes, and to improve the volume, curl, etc. of the eyelashes. Illustratively, mascara having a heating function is disclosed in Patent Publication No. 20-2009-0012373.

However, when using a mascara having a heating function, the entire brush or the applicator having an applicator is heated by the heating unit, and when the mascara container and the handle part are sealed, the mascara contained in the brush and the applicator in the mascara container Submerged in the composition. Therefore, the mascara composition contained in the mascara container is also heated to increase the temperature. Furthermore, for use, when the handle is opened or closed, the brush holder and the applicator are cooled by a temperature difference from the ambient temperature, and when the handle is sealed in the mascara container after use, it is placed in the mascara container by the cooled brush holder and the applicator. The mascara composition is allowed to cool. That is, in the case of the mascara having a heating function, as the use is repeated, the mascara composition in the container repeats heating and cooling.

In general, in the case of mascara having no heating function, the temperature change of the mascara composition is less than 10 ° C depending on the use, but in the case of mascara having a heating function, the temperature change is about 50-60 ° C.

By repetition of heating and cooling, the existing mascara composition sensitive to temperature changes has a change in physical properties, and in particular, the viscosity of the composition changes, which makes it difficult to fulfill the functions and roles of the original mascara composition.

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

The term “make-up composition” disclosed in this specification has a meaning including all of the composition used for skin makeup. The mascara composition of the present specification may be a makeup composition.

The term “mascara” disclosed in the present specification basically includes a container containing a mascara composition (liquid), a handle for opening and closing the container, and a rod-shaped brush stand protruding downward from the handle and the brush stand It includes an applicator formed in the lower portion, and if used for the beauty of the eyelashes, there is no limitation in form. In addition, the mascara disclosed herein may be a mascara that further includes a heating unit having a heating function on the handle, and there is no limitation on the shape of the heating unit.

The term "mascara composition" disclosed herein is stored in a mascara container and means a liquid used for makeup such as eyelashes using an applicator.

The mascara composition of the present invention may be a continuous anhydride in the form of an emulsion or dispersant, or an emulsion comprising some aqueous phase. The continuous anhydride is an oil-dispersion formulation, which is a dispersion formulation without water, and becomes an emulsion when an aqueous phase is included. The emulsion can be O / W or W / O. In one aspect, the mascara composition of the present invention is a continuous dispersion an oil-dispersed formulation is the main formulation.

The mascara composition of the present invention may include a fat phase comprising wax, oil, thickener or mixtures thereof.

The wax is a low-density or medium-density polyethylene wax such as Performalene PL, paraffin wax, and a linear saturated hydrocarbon such as microcrystalline wax as a main component, and may be a solid wax at room temperature. The waxes are not sensitive to temperature changes and may serve as a plasticizer when mixed with other crystalline waxes. That is, the wax of the present invention is microcrystalline and has very good plasticity, so that the crystal structure can be refined when mixed with a conventional crystalline wax, so that the structure of the crystal does not grow even after repeated heating and cooling, so that it can be stable.

While the existing mascara composition contains a large amount of crystalline wax, the mascara composition of the present invention does not contain a crystalline wax, or includes a crystalline wax and a wax based on the above-mentioned linear saturated hydrocarbon. In one aspect, the mascara composition may contain about 10% by weight or less based on the total content of the crystalline wax, and the microcrystalline wax also has a function to refine the crystalline wax.

Existing mascara compositions contain a large amount of crystalline wax, and thus have a melting point. Therefore, when heated to a temperature higher than the final melting point, it becomes common to exhibit an amorphous state within a very short time, and exhibit physical properties that change back to a crystalline state while being cooled. That is, the properties of the composition change due to repeated heating and cooling. In the conventional mascara composition, when heated, crystallization of the wax in the composition having a melting peak is accelerated, and when heating and cooling are repeated, the area of the melting peak is increased. However, the mascara composition of the present invention has no specific melting point and no melting peak. Therefore, in the oil-dispersion composition having no melting point, the solvent is rapidly volatilized by heating to enable setting / curling of the eyelashes, and stability of the composition is maintained even after repeated heating and cooling. 1 is a graph showing a melting peak of a mascara composition comprising crystalline wax (Carnauba) or microcrystalline wax (Polyethylene 90) by way of example (see FIG. 1). Here, the melting peak refers to a peak appearing in a thermal profile obtained by a differential scanning calorimeter (DSC), and the melting point refers to the temperature of the peak (top) of the melting peak. DSC is a device that measures the temperature and heat flow associated with a material's transition as a function of time and temperature. The melting peak of the mascara composition containing the crystalline wax of FIG. 1 has a similar graph shape when the crystalline wax is candelilla, beads, rice bran (rice bran wax), or the like.

The content of the wax may be 1 to 50% by weight based on the total weight of the total composition. Wax is less than 1% by weight, the effect on the formulation is negligible, and 50% by weight or more is because there is a problem that the feeling of stiffness. In one aspect, the wax content may be 10 to 30% by weight based on the total weight of the total composition.

The oil may include one or more selected from the group consisting of volatile or non-volatile hydrocarbons, silicone oils and combinations thereof. The oil is, for example, dimethyl silicone oil, methylphenyl silicone oil, methyl hydrogen silicone oil, methyl hydroxy silicone oil, fluorosilicone oil, polyoxyether copolymer, alkyl-modified silicone oil, higher fatty acid-modified silicone oil, Amino-modified silicone oils, epoxy-modified silicone oils, heavy isoparaffins, squalane, and liquid paraffins.

The oil may include 5 to 30% by weight on one side and 7 to 25% by weight on the other side relative to the total weight of the total composition. This is because, if it is less than 5% by weight, the effect on the formulation is minimal and formation of the formulation is difficult when it is more than 30% by weight.

The thickener can be selected from lipophilic, organic, inorganic and mixtures thereof. The thickener is added to increase the viscosity of the composition, for example, aramid gum, tragant gum, galactan, carob gum, guar gum, carrageenan, pectin, agar, starch (corn, wheat, sweet potato, Plant-based polymers such as rice), microbial-based polymers such as dextran and flurane, starch-based polymers such as dextrin myristate, carboxymethyl starch, methylhydroxypropyl starch, animal-based polymers such as collagen, casein, and gelatin, methylcellulose, Cellulosic polymers such as nitrocellulose, ethylcellulose, hydroxyethylcellulose, sodium sulfate, hydroxypropylcellulose, carboxymethylcellulose, crystalline cellulose, alginic acid polymers such as sodium alginate, propylene glycol ester alginate, polyvinylmethylether, and carboxylate Vinyl polymer such as vinyl polymer, POE polymer, POE poly Examples include oxypropylene copolymer-based polymers, acrylic polymers such as sodium polyacrylate and polyacrylic acid amide, and inorganic water-soluble polymers such as polyethyleneimine, cationic polymer, bentonite, aluminum magnesium silicate, laponite, hectorite, and silicic anhydride. It is not limited.

The thickener may contain 0.05 to 15% by weight on one side and 0.1 to 13% by weight on the other side relative to the total weight of the total composition. If the content of the thickener is less than 0.05% by weight, the role as a thickener is not sufficient, and if it exceeds 15% by weight, the viscosity increase and the clumping of the eyelashes appear severely due to excessive use of the thickener, making it difficult to obtain a clean makeup effect.

The mascara composition of the present invention may further include a pigment. The pigment may be iron oxide, D & C, FD & C colorant, or lakes thereof, and specific examples include red, yellow iron, black iron oxide, ultramarine, iron titanated mica, aluminum, a salt of barium or calcium, carbon black, or Rake, and the like.

The content of the pigment may be 0.1 to 20% by weight on one side and 1 to 10% by weight on the other side relative to the total weight of the total composition.

The mascara composition of the present invention may further include a film-forming polymer, and may be of a dispersion type, an emulsion type, or an emulsion polymerization type. The film-forming polymer, when applied to the eyelashes, forms a film film, enabling the curling effect on the keratin fibers or setting to a desired shape. As the film-forming polymer, there is no stickiness and a film-forming agent that enables the formation of a uniform film film, such as a vinyl polymer, an acrylate copolymer, an alkyl acrylate copolymer, an acrylic system, a silicone system, a siloxane system, a silane system, or the above. And combinations of two or more of polymers, and specifically, for example, hydrogenated polycyclopentadiene, polyvinyl acetate, polyvinyl alcohol, polyvinyl pyrrolidone, polyacrylate, polymeta Acrylate and the like.

The film-forming polymer may be 1 to 30% by weight on one side and 5 to 20% by weight on the other side relative to the total weight of the total composition. If the content of the film-forming polymer is less than 1% by weight, it is difficult to form a film film on the eyelashes, and smearing may occur under the eyes, and the curling effect or setting force is deteriorated. In addition, if it exceeds 30% by weight, there is a disadvantage that the film coated on the keratin fibers is too strong to be erased.

The mascara composition of the present invention may further include emulsifiers, antifoaming agents, preservatives, fragrances, ultraviolet absorbers, moisturizers, and the like, within the scope of not impairing the objects and effects of the present invention, in addition to the above components.

The mascara composition of the present invention, due to repeated use of conventional mascara, even if heating in the range of 80 to 90 ° C and cooling in the range of 20 to 30 ° C is repeated, the viscosity change of the mascara composition is 30% or less at one side, and the other side It is a composition that varies from 15% or less. The change in viscosity can be measured with a Brookfield viscometer.

The mascara composition of the present invention may be an anhydrous phase containing a volatile solvent, in particular a silicone, hydrocarbon, or fluorine-based solvent, and in an exemplary embodiment, the solvent may be isododecane, isoparaffin, and the like, but is not limited thereto. The non-aqueous solvent can promote the curling effect of the eyelashes and increase the holding power. That is, the solvent can protect the disulfide bonds in the hair and keep the finished curl for a long time. Except for using purified water or isododecane as a solvent, a photograph of a mascara composition prepared by applying the same composition to all the lashes is shown in FIG. 4 (see FIG. 4). Looking at Figure 4, it can be seen that the curling effect of the mascara composition using anhydrous solvent is more excellent.

  The oil-dispersion formulation of the mascara of the present invention can be prepared by heating a wax, dissolving it in a solvent, dispersing it in a pigment, and cooling it by introducing other compositions such as a film-forming polymer. In addition, the emulsion formulation can be prepared by dissolving the wax in a solvent, dispersing it in a pigment, preparing the oily part separately from the water phase part, heating it, and then adding another composition to cool it.

Hereinafter, the configuration and effects of the present invention will be described in more detail with reference to Examples and Experimental Examples. However, these examples and experimental examples are provided for illustrative purposes only to aid understanding of the present invention, and the scope and scope of the present invention are not limited thereto.

[Example 1]

A mascara composition of an oil-dispersion formulation was prepared according to a conventional method for preparing a mascara composition, and the following composition was used.

-Wax (2% by weight of polyethylene wax + 2% by weight of paraffin wax)

-Oil (7% by weight of dimethylsilicone oil)

-Thickener (4% by weight bentonite + 8% by weight dextrin myristate)

-Film-forming polymer (DC MQ 1640 resin (DOW CORNING®) 10 wt% + granacrysil BMAS (Grant Industry) 10 wt%)

-Solvent (isododecane + isoparaffin to 100)

-Pigment (appropriate amount)

[Experimental Example 1]

The stability of the mascara composition of Example 1 against temperature changes was tested. After placing the mascara composition at 90 ° C. for 1 hour, and then standing at 30 ° C. for 2 hours, the viscosity of the composition was measured. The experiment is based on the reality of the use of a typical mascara composition. Usually, mascara is used for 3 months, and if it is used 90 times, 4 minutes per session, it is used for a total of 6 hours. The conditions were changed by the accelerated experiment, and the heating and cooling were repeated 15 times (cycle) as harsher conditions than in the case of normal use. This is the same condition as heating the mascara composition for about 15 hours. If the viscosity variation of the mascara composition between the first cycle and the last cycle is less than 25%, it can be considered stable for repetitive heating and cooling, and it can be concluded that the physical properties of the composition are not altered.

For comparison, the general mascara composition (Etude Espoir Ultimate Feather Volume Mascara, Cosvision, manufacturer) was also heated and cooled in the same manner as above. The viscosity of the mascara composition of Example 1 and the general mascara composition were measured before the first experiment (0 times), and the viscosity after heating and cooling cycles up to 15 times in 2 units was measured.

Viscosity measurements were made using a Brookfield HADV-III U viscometer equipped with an LV spindle (spindle) operating at a 50/60 Hz power supply.

The results are shown in Fig. 2 (see Fig. 2). In Fig. 2, the green graph is for the general mascara composition, and the red graph is for the mascara composition of the present invention (Example 1). In the case of the general mascara, after 3 cycles, the viscosity of the composition was already very high, and thus it was difficult to measure the viscosity in the same manner as in the first case. In the case of the mascara composition of Example 1, the viscosity deviation of less than 25% after 15 cycles Shown.

[Experimental Example 2]

10 mg of the common mascara composition and the mascara composition of Example 1 were respectively added to an aluminum sampler, and after heating at 20 ° C to 90 ° C at a rate of 5 ° C / min, the cycle of cooling from 90 ° C to 20 ° C was repeated 15 times. . Ta DSC's DSC Q1000 instrument was used to measure the change in temperature over time of the composition, which was graphically shown in FIG. 3 (see FIG. 3). In the case of the mascara composition of Example 1, the melting point and melting peak were not visually discernable.
