Description

[Technical Field]

[0001] The present disclosure relates to lip cosmetic compositions that include a colorant. [Background technology]

[0002] Conventionally, lip cosmetics have mainly been products with high saturation colors. However, in recent years, interest in diverse colors has increased, and there is a growing need for low-saturation, toned-down colors. To meet such needs, blue colorants can be used to tone down the color, or titanium dioxide can be used to impart opacity.

[0003] However, blue colorants can only achieve a cool blue color, and their unique color can cause darkening and dull lips. Titanium dioxide also tends to precipitate and aggregate in the water portion of the formulation, making it difficult to disperse and potentially causing quality issues. Furthermore, when titanium dioxide is used in combination with a colorant, the colorant and titanium dioxide may not blend well together, resulting in a white, tangled appearance on the lips (a yogurt-like phenomenon, also known as a "white ring"), preventing maximum color realization and dyeing effectiveness.

[0004] Therefore, there is a need to develop lip cosmetics that can achieve a wide range of colors and maximize the coloring effect when applied to the lips, while minimizing darkening and the yogurt-like phenomenon. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0010] The various examples and terms used in this specification should not be understood to limit the technology described herein to a particular example, but should be understood to include various modifications, equivalents, or alternatives to the example.

[0011] One aspect of the present disclosure provides a lip cosmetic composition comprising a green colorant and titanium dioxide (TiO2) coated with a hydrophilic compound.

[0012] "Colorant" may refer to a substance added to a food, drug, or cosmetic product for the purpose of coloring it, and may include, for example, a dye. For example, a colorant may be a natural or synthetic colorant. For example, a colorant may be an organic or inorganic substance.

[0013] According to one embodiment, the green colorant may be, but is not limited to, a green dye.

[0014] According to one embodiment, the green colorant may be at least one selected from the group consisting of, but not limited to, a green organic dye or a green inorganic dye.

[0015] According to one embodiment, the green colorant may be an aryl-based green colorant.

[0016] The term "aryl-based" compound may refer to a compound containing an aryl. The term "aryl" may refer to a wholly or partially unsaturated, substituted or unsubstituted, monocyclic or polycyclic carbocyclic ring. Aryl may include fused aryl. Aryl may be substituted or unsubstituted.

[0017] The term "fused aryl" may refer to a ring consisting of multiple fused aryl rings, and may include, for example, naphthalene, phenanthrene, anthracene, benzopyrene, acenaphthalene, acenaphthene, chrysene, fluoranthene, fluorene, pyrene, and the like.

[0018] According to one embodiment, the aryl-based green colorant may be at least one selected from the group consisting of anthraquinone-based green pigments, triphenylmethane-based green pigments, and pyrene-based green pigments, but is not limited thereto.

[0019] According to one embodiment, the aryl green colorant may be at least one selected from the group consisting of, but not limited to, Green No. 3 (CI No. 42053), Green No. 201 (CI No. 61570), Green No. 202 (CI No. 61565), and Green No. 204 (CI No. 59040).

[0020] By including a green colorant, the cosmetic composition according to one aspect of the present disclosure can achieve coloring power that does not become dull after dyeing, and can prevent significant darkening even after a predetermined time has passed since dyeing.

[0021] The cosmetic composition according to one embodiment of the present disclosure includes a green colorant, thereby enabling the realization of colors with a variety of brightness and saturation that are difficult to achieve with a blue colorant. According to one embodiment, when a green colorant is used in combination with a colorant of another color (e.g., a red colorant), colors with a variety of brightness and saturation can be achieved. On the other hand, when a blue colorant is used in combination with a colorant of another color (e.g., a red colorant), even a small amount of the blue colorant is used, resulting in a significant decrease in brightness, making it relatively difficult to achieve a variety of colors.

[0022] According to one embodiment, the lip cosmetic composition according to one aspect of the present disclosure may not contain a blue colorant.

[0023] According to one embodiment, the lip cosmetic composition may further include another colorant different from the green colorant, and the color of the other colorant may be different from that of the green colorant.

[0024] According to an embodiment, the other colorant is not particularly limited in type, as long as it can be mixed with the green colorant to realize various colors.

[0025] According to one embodiment, the other colorant may not be a blue colorant, but may be a red colorant, for example, Red No. 227.

[0026] It is known that colorants can maximize color realization and dyeing effects by effectively dissolving and dispersing them in the water portion of an oil-in-water or water-dispersible composition. However, titanium dioxide (TiO2), which is primarily used to achieve white, tends to aggregate and / or precipitate in water, making it difficult to disperse. When used in combination with other colorants, it separates due to incompatibility with the other colorants, resulting in a whitish, tangled appearance when applied to the skin, lips, or other parts of the human body. The cosmetic composition according to one embodiment of the present disclosure contains titanium dioxide coated with a hydrophilic compound, which provides excellent dispersibility and stability in water and prevents re-aggregation and precipitation, thereby exhibiting stability even in oil-in-water emulsion formulations, allowing for excessive use, ultimately achieving a variety of colors and enhancing dyeing effects. Furthermore, the cosmetic composition according to one embodiment of the present disclosure contains titanium dioxide coated with a hydrophilic compound, which allows it to be mixed with a green colorant without separation, resulting in a beautiful cosmetic look when applied to the skin or lips.

[0027] According to one embodiment, the green colorant may be contained in the cosmetic composition in an amount of 0.001 to 5 wt % relative to the total weight of the composition, but is not limited thereto. For example, the green colorant may be contained in the cosmetic composition in an amount of 0.001 wt % or more, 0.01 wt % or more, 0.02 wt % or more, 0.03 wt % or more, 0.04 wt % or more, 0.05 wt % or more, 0.06 wt % or more, 0.07 wt % or more, 0.08 wt % or more, 0.09 wt % or more, 0.1 wt % or more, 0.2 wt % or more, 0.3 wt % or more, 0.4 wt % or more, 0.5 wt % or more, 0.6 wt % or more, 0.7 wt % or more, 0.8 wt % or more, 0.9 wt % or more, 1 wt % or more, 2 wt % or more, 3 wt % or more, 4 wt % or more, 5 wt % or more, or the like, relative to the total weight of the cosmetic composition. % or more, and may be present at 0.001% by weight or less, 0.01% by weight or less, 0.02% by weight or less, 0.03% by weight or less, 0.04% by weight or less, 0.05% by weight or less, 0.06% by weight or less, 0.07% by weight or less, 0.08% by weight or less, 0.09% by weight or less, 0.1% by weight or less, 0.2% by weight or less, 0.3% by weight or less, 0.4% by weight or less, 0.5% by weight or less, 0.6% by weight or less, 0.7% by weight or less, 0.8% by weight or less, 0.9% by weight or less, 1% by weight or less, 2% by weight or less, 3% by weight or less, 4% by weight or less, 5% by weight or less, or any combination thereof.

[0028] According to one embodiment, the titanium dioxide coated with a hydrophilic compound may be titanium dioxide that has been surface-treated with a hydrophilic compound. For example, titanium dioxide coated with a hydrophilic compound has a form in which the hydrophilic compound surrounds the surface of the titanium dioxide. According to one embodiment, titanium dioxide coated with a hydrophilic compound may be obtained by spraying and mixing a hydrophilic compound (e.g., phytic acid) onto titanium dioxide, followed by heat treatment. At this time, the mixture may be stirred. According to one embodiment, titanium dioxide coated with a hydrophilic compound may be obtained by a gas-phase reaction or a surface treatment method using a slurry.

[0029] The "hydrophilic compound" is a compound having hydrophilic properties, and may be, for example, a hydrophilic organic compound or a hydrophilic inorganic compound. The hydrophilic compound may be, but is not limited to, a hydrophilic polymer compound or a hydrophilic low molecular weight compound.

[0030] According to one embodiment, the hydrophilic compound may be at least one selected from the group consisting of inositol, inositol salts, inositol phosphate esters, salts of inositol phosphate esters, alginic acid, and alginates.

[0031] According to one embodiment, the inositol phosphate ester may be at least one selected from the group consisting of, but not limited to, inositol hexaphosphate, inositol pentaphosphate, inositol tetraphosphate, inositol triphosphate, inositol diphosphate, and inositol monophosphate. Inositol hexaphosphate is also known as phytic acid.

[0032] According to one embodiment, the salt of inositol phosphate ester may be at least one selected from the group consisting of salts of inositol hexaphosphate, salts of inositol pentaphosphate, salts of inositol tetraphosphate, salts of inositol triphosphate, salts of inositol diphosphate, and salts of inositol monophosphate, but is not limited thereto. The salt of inositol hexaphosphate may be phytate. Phytate may be a form in which a metal salt (e.g., calcium, potassium, magnesium, etc.) is bound to phytic acid.

[0033] According to one embodiment, the hydrophilic compound may be at least one selected from the group consisting of phytic acid, phytate, alginic acid, and alginate. According to one embodiment, the hydrophilic compound may be at least one of phytic acid or sodium alginate.

[0034] According to one embodiment, the hydrophilic compound may have a hydrophile-lipophile balance (HLB) of, but is not limited to, 8 to 18. For example, the hydrophilic compound may have an HLB of 8 or more, 9 or more, 10 or more, 11 or more, 12 or more, 13 or more, 14 or more, 15 or more, 16 or more, 17 or more, or 18 or more, and may have an HLB of 8 or less, 9 or less, 10 or less, 11 or less, 12 or less, 13 or less, 14 or less, 15 or less, 16 or less, 17 or less, or 18 or less, or any combination thereof.

[0035] In this specification, "HLB" indicates the hydrophile-lipophile balance, which is calculated according to the Griffin's method using the following formula 1, and is expressed as a numerical value of 0 to 20. The higher the HLB value, the higher the hydrophilicity.

[0036] According to one embodiment, the titanium dioxide coated with a hydrophilic compound may be contained in the cosmetic composition in an amount of 0.05 to 10 wt % based on the total weight of the cosmetic composition, but is not limited thereto. For example, the titanium dioxide coated with a hydrophilic compound may be present in the cosmetic composition in an amount of 0.05% by weight or more, 0.1% by weight or more, 0.2% by weight or more, 0.3% by weight or more, 0.4% by weight or more, 0.5% by weight or more, 0.6% by weight or more, 0.7% by weight or more, 0.8% by weight or more, 0.9% by weight or more, 1% by weight or more, 1.5% by weight or more, 2% by weight or more, 2.5% by weight or more, 3% by weight or more, 3.5% by weight or more, 4% by weight or more, 4.5% by weight or more, 5% by weight or more, 5.5% by weight or more, 6% by weight or more, 6.5% by weight or more, 7% by weight or more, 7.5% by weight or more, 8% by weight or more, 8.5% by weight or more, 9% by weight or more, 9.5% by weight or more, % or more by weight, 10% or more by weight, and may be present at 0.05% or less, 0.1% or less, 0.2% or less, 0.3% or less, 0.4% or less, 0.5% or less, 0.6% or less, 0.7% or less, 0.8% or less, 0.9% or less, 1% or less, 1.5% or less, 2% or less, 2.5% or less, 3% or less, 3.5% or less, 4% or less, 4.5% or less, 5% or less, 5.5% or less, 6% or less, 6.5% or less, 7% or less, 7.5% or less, 8% or less, 8.5% or less, 9% or less, 9.5% or less, 10% or less by weight, or any combination thereof.

[0037] If the content of titanium dioxide coated with a hydrophilic compound is less than 0.05% by weight, the white color is not effectively developed and it is difficult to achieve a neutral color tone. If the content exceeds 10% by weight, problems arise such as the titanium dioxide precipitating in the composition or caking occurring.

[0038] The term "caking phenomenon" refers to the phenomenon of solidification and formation of lumps. The occurrence of caking phenomenon in a composition may indicate poor dispersion of the components contained in the composition.

[0039] According to one embodiment, the lip cosmetic composition may be, but is not limited to, an oil-in-water (O / W) or water-dispersed formulation.

[0040] When the lip cosmetic composition according to one embodiment of the present disclosure is formulated as an oil-in-water type or a water-dispersible type, the titanium dioxide coated with a green colorant and / or a hydrophilic compound is well dispersed in the water portion. When the titanium dioxide coated with a green colorant and / or a hydrophilic compound is well dispersed in the water portion, a variety of colors, particularly a variety of dyeing colors, can be realized, and the dyeing effect can be improved.

[0041] According to one embodiment, the lip cosmetic composition may be formulated as at least one product selected from the group consisting of lip tint, lipstick, lip balm, lip cream, lip pencil, liquid lipstick, and lip gloss.

[0042] One aspect of the present disclosure may provide a lip cosmetic comprising a green colorant and titanium dioxide (TiO2) coated with a hydrophilic compound. The green colorant and the titanium dioxide coated with a hydrophilic compound have been described above, so a detailed description thereof will be omitted.

[0043] According to one embodiment, the lip cosmetic may be at least one selected from the group consisting of lip tint, lipstick, lip balm, lip cream, lip pencil, liquid lipstick, and lip gloss.

[0044] The lip cosmetic composition and / or method according to one embodiment of the present disclosure can achieve colors of various brightnesses and saturations. The lip cosmetic composition according to one embodiment of the present disclosure can achieve a wide range of colors that are difficult to achieve with conventional blue colorants.

[0045] When applied to the lips, the lip cosmetic composition according to one aspect of the present disclosure allows for the expression of a transparent color, and does not cause darkening even after a predetermined period of time has passed.

[0046] When applied to the lips, the lip cosmetic composition according to one aspect of the present disclosure does not produce a yogurt-like phenomenon, and can be applied neatly.

[0047] The lip cosmetic composition according to one embodiment of the present disclosure can achieve colors of various brightness and saturation, and when applied to the lips, it can achieve a transparent color expression without causing darkening, and at the same time, it can prevent the occurrence of a yogurt-like phenomenon (white cast phenomenon) on the lips.

[0048] The "yogurt-like phenomenon" refers to a phenomenon in which, when a cosmetic composition is applied to the lips, some components of the composition react with saliva or other substances, causing the lips to separate and appear white. The yogurt-like phenomenon is also known as the "white ring" phenomenon.

[0049] One aspect of the present disclosure provides a lip makeup method comprising the steps of: applying the aforementioned lip cosmetic composition.

[0050] One aspect of the present disclosure provides a method for coloring lips, comprising the steps of applying the aforementioned lip cosmetic composition.

[0051] In one implementation, applying the lip cosmetic composition may be applying the lip cosmetic composition to the lips of the subject.

[0052] The lip cosmetic composition has been described above, so a detailed description thereof will be omitted.

[0053] By using the lip makeup method and / or lip coloring method according to one embodiment of the present disclosure, it is possible to achieve colors of various brightness and saturation, and it is possible to express transparent colors on the lips without causing darkening, and at the same time, it is possible to prevent the occurrence of a yogurt-like phenomenon (white cast phenomenon) on the lips.

[0054] One aspect of the present disclosure provides a use of the aforementioned lip cosmetic composition for producing a cosmetic composition for lip make-up.

[0055] The lip cosmetic composition has been described above, so a detailed description thereof will be omitted.

[0056] The present invention will be described in detail below with reference to examples, which are provided to aid in understanding the present invention and are not intended to limit the scope of the present invention.

[0057] 1. Preparation of lip cosmetic composition Cosmetic compositions of Examples 1 and 2 and Comparative Examples 1 to 4 were prepared using the formulations in Table 1 below (units in Table 1: weight %). Specifically, the colorant components in Table 1 were dispersed and mixed into the aqueous phase components and heated to 60°C. Among the colorants, Green No. 201 had a color intensity that was one-third that of Blue No. 1, so Green No. 5 was used in a content three times that of Blue No. 1 to achieve similar color intensity. The oil phase components were then slowly added and mixed. After emulsification, the powder was mixed using a mixer at a speed of 1000 to 3000 rpm for 5 minutes. The mixture was then cooled and completely degassed to prepare oil-in-water makeup cosmetic compositions.

[0058] [Table 1]

[0059] In Table 1, titanium dioxide * phytic acid refers to titanium dioxide coated with phytic acid, titanium dioxide * sodium alginate refers to titanium dioxide coated with sodium alginate, and titanium dioxide * triethoxycaprylylsilane refers to titanium dioxide coated with alkylsilane, specifically, titanium dioxide coated with triethoxycaprylylsilane. Titanium dioxide * phytic acid was prepared by spraying phytic acid, which has a hydrophilic group, onto titanium dioxide, adding it to a mixer, and stirring until thoroughly mixed. A surface-treated powder (titanium dioxide * phytic acid) coated with phytic acid was then obtained by a heat treatment process. Titanium dioxide * sodium alginate was prepared in the same manner as titanium dioxide * phytic acid, except that sodium alginate was used instead of phytic acid. Titanium dioxide*triethoxycaprylylsilane was prepared similarly to the titanium dioxide*phytic acid preparation method, except that triethoxycaprylylsilane was used in place of phytic acid.

[0060] In addition, in Table 1, titanium dioxide*silica is a silica-composite titanium dioxide that is widely used on the market as water-dispersible titanium dioxide (product name: SIH-5 TiO2 R250 / manufacturer: Daito Kasei).

[0061] 2. Evaluation of titanium dioxide dispersibility, formulation stability, and yogurt-like phenomenon on the lips depending on its form (1) Dispersibility evaluation 1 g of each of the cosmetic compositions of Examples 1 and 2 and Comparative Examples 2 to 4 was mixed with 99 g of water, and immediately after mixing, the dispersibility was confirmed. In addition, the settling rate after mixing and the occurrence of caking were evaluated.

[0062] [Table 2]

[0063] As shown in Table 2, Comparative Example 4, which contained uncoated titanium dioxide, was immediately dispersible, but precipitated very quickly, resulting in caking. Comparative Example 3, which contained alkylsilane-coated titanium dioxide, aggregated immediately after mixing and did not disperse at all. Comparative Example 2, which contained silica-composite titanium dioxide, was immediately dispersible and had a slow precipitation rate, but some caking was observed.

[0064] Similar to Example 1, a composition was also prepared using titanium dioxide and phytic acid at a content of more than 10% by weight, and dispersibility was evaluated. As a result, when the titanium dioxide and phytic acid content in the composition exceeded 10%, precipitation or caking readily occurred (see the left container in Figure 1).

[0065] (2) Evaluation of formulation stability and occurrence of yogurt-like phenomenon on the lips The cosmetic compositions of Example 1 and Comparative Example 2 were stored in a thermostatic chamber at 55°C, and the formulation stability was confirmed after 3 days. In addition, the cosmetic compositions of Example 1 and Comparative Example 2 were each applied to the lips to check whether or not a yogurt-like phenomenon occurred.

[0066] In Example 1, which used titanium dioxide coated with phytic acid, the dispersibility of the contents was maintained even after three days in a constant temperature bath, and no separation of the formulation occurred. On the other hand, in Comparative Example 2, which used titanium dioxide composited with silica, separation of the formulation occurred (see the photograph on the left side of Figure 2). Furthermore, when Example 1, which used titanium dioxide coated with phytic acid, was applied to the lips, it spread smoothly. On the other hand, in Comparative Example 2, which used titanium dioxide composited with silica, it separated into white on the lips and appeared unattractive, a phenomenon thought to occur because titanium dioxide tends to aggregate on the lips (see the photograph on the right side of Figure 2). The yogurt-like phenomenon on the lips is thought to be related to the stability of the formulation.

[0067] 3. Color evaluation of cosmetic compositions with or without green colorants The color of the cosmetic composition of Example 1 was compared with the color after dyeing in Comparative Example 1. As described in "1. Preparation of lip cosmetic composition" above, the color intensity of the green colorant among the colorants is one-third of that of the blue colorant, so to achieve similar color intensity, Green No. 5 was used in an amount three times that of Blue No. 1 to prepare the contents.

[0068] Visual inspection revealed that Example 1 and Comparative Example 1 exhibited similar color strength, but Example 1, which used a green colorant, achieved a relatively yellowish transparent color (see the upper photograph in Figure 3). Comparing the colors after dyeing, Example 1, which used a green colorant, was able to achieve coloring strength without dullness. On the other hand, Comparative Example 1, which used a blue colorant, exhibited a relatively dull color (see the lower photograph in Figure 3). This demonstrates that the green colorant has an excellent function of deepening colors.

[0069] 4. Evaluation of the feasibility of various colors depending on whether or not green colorant is included We confirmed that the use of a green colorant by adjusting the content of the green and blue colorants allowed for a variety of colors to be achieved. Specifically, cosmetic compositions were prepared in the same manner as in Example 1, except that the content of Green No. 201 was adjusted, and in the same manner as in Comparative Example 1, except that the content of Blue No. 1 was adjusted. The degree of decrease in brightness of the prepared cosmetic compositions was measured using a colorimeter (SCI, device name: CM-5, manufacturer: Konica Minolta). As a result, the use of a blue colorant significantly decreased brightness even with a small amount, making it difficult to achieve fine, refined color matching. On the other hand, the use of a green colorant allowed for a variety of colors with greater brightness than when using a blue colorant. As shown in Figure 4, the slope of the brightness / content graph obtained using the colorimeter was approximately -7.7 when the blue colorant was used and approximately -3.1 when the green colorant was used. This indicates that the use of a green colorant allows for more than twice as precise color matching (see Figure 4). Furthermore, it is found that in order to similarly adjust the brightness of the final product (for example, a cosmetic composition), the green colorant must be used in an amount about 3 to 4 times that of the blue colorant.

[0070] It was also confirmed that the use of a green colorant resulted in a more diverse range of toned-down, subdued colors. Specifically, four toning tests were performed using a blue colorant and a red colorant (Comparative Test Examples 1-4 in Figure 5). The four toning tests using the blue colorant were performed under the same conditions, except for a slight adjustment of the blue colorant content. Four toning tests were also performed using a green colorant and a red colorant (Test Examples 1-4 in Figure 5). The four toning tests using the green colorant were performed under the same conditions, except for a slight adjustment of the green colorant content. Meanwhile, the four toning tests using the green colorant were performed under the same conditions as the four toning tests using the blue colorant, except that three times the amount (by weight) of the green colorant was used instead of the blue colorant. That is, in Figure 5, Test Example 1 was toned in the same manner as Comparative Test Example 1, except that three times the amount of the green colorant was used instead of the blue colorant. In addition, Test Example 2 was toned in the same manner as Comparative Test Example 2, except that three times the amount of green colorant was used instead of the blue colorant. Test Example 3 was toned in the same manner as Comparative Test Example 4, except that three times the amount of green colorant was used instead of the blue colorant. Test Example 4 was toned in the same manner as Comparative Test Example 4, except that three times the amount of green colorant was used instead of the blue colorant. This was set in consideration of the above experimental results, which confirmed that in order to similarly adjust the brightness of the final product, the green colorant should be used in an amount approximately three to four times that of the blue colorant.

[0071] It was confirmed that using a green colorant to tone down colors allows for a wider variety of colors to be achieved than when using a blue colorant. Using a green colorant, it was possible to achieve toned-down, muted colors (such as warm wine and muted purple), but using a blue colorant, it was not easy to achieve muted colors (see Figure 5). Because green is the complementary color of red, it is thought that it can achieve more muted, warm colors.

[0072] 5. Panel evaluation A panel of 20 female subjects aged 25 to 39 evaluated the color expression and color durability of the Examples and Comparative Examples when they were applied to the lips. The evaluation was on a 5-point scale, with higher scores being given for better results in each category. The average values of the 20 panelists for each category are shown.

[0073] As shown in Table 3, when a green colorant was used, not only was the color transparent and attractive, but there was also no darkening of the color. On the other hand, when a blue colorant was used instead of a green colorant (Comparative Example 1), the color darkened after a certain period of time, making the lips appear dull. Furthermore, when titanium dioxide coated with an alkylsilane was used instead of titanium dioxide coated with a hydrophilic compound (Comparative Example 2), the color was not beautifully expressed on the lips, and low scores were given in the item evaluating whether it looked good on the lips.
