Description

Cosmetic composition with excellent cooling sensation containing sodium carbomer

[0001] The present invention relates to a cosmetic composition with excellent cooling sensation, and to a cosmetic composition that achieves a unique sensation when applied to the skin through a combination of sodium carbomer and an emulsifier, and can exhibit excellent skin moisturizing and cooling effects immediately after use.

[0002] Recently, as climate polarization progresses, summers have become longer, and sweltering heat persists. Consequently, heat-induced aging is occurring, in which collagen and elastic fibers within the skin are destroyed at a rapid pace due to rising temperatures. Therefore, interest in "cooling cosmetics" is growing, as they provide a refreshing sensation by lowering the perceived temperature of the skin's surface. Cooling cosmetics lower skin temperature the moment they are applied, revitalizing skin that has become tired and lifeless due to high temperatures and humidity.

[0003] Generally, cooling cosmetics that provide these functions are made by adding alcohol ingredients to provide a cooling effect based on the principle that the alcohol takes away heat from the skin as it evaporates, or by using ingredients such as menthol, menthol derivatives, and xylitol as cooling agents to lower the skin temperature and give a cool sensation.

[0004] However, these alcohol or menthol ingredients have side effects such as skin redness, skin trouble, and allergies due to skin irritation, so there is a need to develop new cooling ingredients that can compensate for this.

[0005] Meanwhile, sodium carbomer is a mixture of sodium (salt) and carbomer, and is an ingredient commonly used as a thickening agent in skincare products to provide a smooth and consistent texture and improve the spreadability of creams and gels.

[0006] The inventors of the present invention confirmed that when sodium carbomer and an emulsifier are optimally combined, a formulation that effectively lowers the temperature of the skin and has a unique feel can be realized, and using this, developed a cosmetic composition that provides high moisturizing properties and excellent cooling properties.

[0007] The present invention aims to provide a cosmetic composition that can lower skin temperature and provide high moisturization when applied to the skin using sodium carbomer.

[0008] The technical problems of the present invention are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art from the description below.

[0009] According to an embodiment of the present invention, a cosmetic composition having excellent cooling sensation comprising sodium carbomer and polyglyceryl-3-methylglucose distearate is provided.

[0010] The cosmetic composition of the present invention can provide a unique sensation of melting smoothly when applied to the skin and can provide an excellent cooling effect by lowering the temperature of the skin immediately after application.

[0011] In addition, when the above cosmetic composition is applied to the skin, it can provide immediate moisture to the skin and prevent moisture loss, thereby exhibiting excellent skin moisturizing power.

In general, the nomenclature used herein is well known and commonly used in the art. Furthermore, in describing embodiments of the present invention, detailed descriptions of related known components or functions are omitted if it is determined that such detailed descriptions would hinder understanding of the embodiments of the present invention. Additionally, while embodiments of the present invention will be described below, the technical concept of the present invention is not limited or restricted thereto and can be modified and implemented in various ways by those skilled in the art.

[0026] In this specification, when a part is described as including a certain component, it means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. In this specification, the term "and / or" includes a combination of a plurality of related items or any one of a plurality of related items.

[0027]

[0028] According to an embodiment of the present invention, a cosmetic composition having excellent cooling properties is provided. The cosmetic composition can stably contain sodium carbomer in the formulation, thereby providing a unique sensation of melting smoothly upon application to the skin and offering excellent cooling properties, as well as exhibiting immediate skin moisturizing effects when applied to the skin.

[0029] The “sodium carbomer” of the present invention refers to a compound having the structure of the following chemical formula I, as a mixture of sodium (salt) and carbomer.

[0030] [Chemical Formula I]

[0031]

[0032] The sodium carbomer of the present invention is a water-soluble thickening agent with excellent ability to absorb and retain water, and is used as a formulation stabilizer for lotion and cream type products. It is used not only as an ingredient that provides a soft and moist spreadability and excellent moisturizing power, but also can provide an immediate skin cooling effect when applied to the skin.

[0033] In a specific embodiment, the sodium carbomer may be included in an amount of 0.1 to 1.4 weight% based on the total weight of the cosmetic composition, specifically 0.2 to 1.2 weight%, more specifically 0.2 to 1.0 weight%, even more specifically 0.2 to 0.8 weight%, and most specifically 0.2 to 0.6 weight%. If the sodium carbomer is included in an amount of less than 0.1 weight% based on the total weight of the cosmetic composition, the formulation may be formed in a liquid form rather than a cream form, and the stability of the formulation may be reduced, such as by the separation of the aqueous and oil phases. If the sodium carbomer is included in an amount exceeding 1.4 weight%, an excess amount of sodium carbomer exceeding the solubility limit may not dissolve, and due to incomplete emulsification, a composition with a thick formulation and high hardness may be formed.

[0034] According to one embodiment of the present invention, the cosmetic composition of the present invention may include polyglyceryl-3-methylglucose distearate together with sodium carbomer.

[0035] The above polyglyceryl-3-methylglucose distearate serves as an emulsifier for forming emulsion particles, and can play a role in enabling the cosmetic composition to form sufficient viscosity and hardness, and stabilizing sodium carbomer within the formulation.

[0036] In one embodiment, the polyglyceryl-3-methylglucose distearate may be included in an amount of 0.1 to 4.5 weight% based on the total weight of the cosmetic composition, more specifically in an amount of 0.1 to 3.0 weight%, and most specifically in an amount of 0.1 to 2.0 weight%. Here, if the polyglyceryl-3-methylglucose distearate is included in an amount of less than 0.1 weight% based on the total weight of the cosmetic composition, a composition with low turbidity and a thin formulation may be formed, and if the polyglyceryl-3-methylglucose distearate is included in an amount exceeding 4.5 weight%, a composition with a formulation that is not completely dispersed and exhibits thick spreadability may be formed, making it difficult to apply to the skin.

[0037] In one embodiment, the sodium carbomer and polyglyceryl-3-methylglucose distearate may be included in a weight ratio of 1:0.2 to 6, specifically, the sodium carbomer and polyglyceryl-3-methylglucose distearate may be included in a weight ratio of 1:0.2 to 5.5, and more specifically, in a weight ratio of 0.2 to 5. When the sodium carbomer and polyglyceryl-3-methylglucose distearate are included in a weight ratio of 1:0.2 to 6, a stable formulation can be formed that provides an immediate cooling sensation and moisturizing effect to the skin by exhibiting a unique texture that is soft and melts smoothly upon application to the skin.

[0038] In one embodiment, the cosmetic composition of the present invention may further include oil in addition to sodium carbomer and polyglyceryl-3-methylglucose distearate.

[0039] In one embodiment, the oil acts as a solvent for the oil phase, maintains skin moisture, and can provide a continuous moisturizing sensation. The oil may be a silicone-based oil, a hydrocarbon-based oil, an ester-based oil, etc., and any oil generally used in the industry may be appropriately selected without limitation. Specific examples of the oil include ester-based oils such as C12-15 alkyl benzoate, dibutyl adipate, butylene glycol dicaprylate / dicaprate, ethylhexyl stearate, and propyl heptyl caprylate; silicone-based oils such as disiloxane, caprylyl methicone, and methyl trimethicone; hydrocarbon-based oils such as isododecane, hydrogenated poly(C6-14 olefin), and C18-21 alkane; at least one of dicaprylyl ether, Argania spinosa kernel oil, and jojoba seed oil may be included, but is not limited thereto.

[0040] In a specific embodiment, the oil may be included in an amount of 0.01 to 14 weight% based on the total weight of the cosmetic composition, specifically in an amount of 0.1 to 14 weight%, and more specifically in an amount of 1 to 14 weight%. Here, if the oil is included in an amount of less than 0.01 weight% based on the total weight of the cosmetic composition, a transparent essence formulation may be formed, which may result in poor spreadability, and if the oil is included in an amount exceeding 14 weight%, the oil content is higher than that of sodium carbomer and emulsifier, so an oil layer may be formed separately, resulting in an unstable formulation.

[0041] In one embodiment, the sodium carbomer and oil may be included in a weight ratio of 1:0.1 to 28, specifically in a weight ratio of 1:1 to 25, and more specifically in a weight ratio of 1:2 to 20. When the sodium carbomer and oil are included in a weight ratio of 1:0.1 to 28, sufficient viscosity and hardness can be formed, and a smooth spreadability can be achieved. Additionally, a unique sensation of melting upon application to the skin can be realized, thereby providing an immediate cooling sensation and moisturizing effect to the skin.

[0042] In one embodiment, the sodium carbomer, polyglyceryl-3-methylglucose distearate, and oil may be included in a weight ratio of 1:0.2 to 6:0.1 to 28, specifically in a weight ratio of 1:0.2 to 5.5:1 to 25, and more specifically in a weight ratio of 1:0.2 to 5:2 to 20. A cosmetic composition comprising the sodium carbomer, polyglyceryl-3-methylglucose distearate, and oil in a weight ratio of 1:0.2 to 6:0.1 to 28 can exhibit an excellent cooling sensation and immediate moisturizing effect on the skin.

[0043]

[0044] In one embodiment, the cosmetic composition of the present invention may additionally include a preservative, a skin conditioning agent, or a functional ingredient in addition to the main ingredient.

[0045] The above preservative is used to enhance the effect of preservation, and for example, at least one of ethylhexylglycerin, 1,2-hexanediol, caprylyl glycol, hydroxyacetophenone, phenoxyethanol, and glyceryl caprylate may be used, but is not limited thereto, and any preservative generally used in the industry may be appropriately selected without limitation.

[0046] The above skin conditioning agent is used to enhance the protective and moisturizing effects of the skin, and at least one of propanediol, 2,3-butanediol, butyllocyl salicylate, caprylyl methicone, butylene glycol, pentylene glycol, glycerin, ethylhexylglycerin, niacinamide, Fragaria ananas (strawberry) calyx extract, and dipotassium glycyrrhizate may be used, but is not limited thereto, and any skin conditioning agent that is generally used in the industry may be appropriately selected without limitation.

[0047] The above functional ingredients may be added by mixing various ingredients according to the purpose of the cosmetic composition, and include, for example, all of the following: wrinkle improvement agents, whitening functional ingredients, pigmentation functional ingredients, skin soothing functional ingredients, and sebum or pore management functional ingredients.

[0048] In addition to this, the cosmetic composition of the present invention may further include ingredients included in general cosmetic compositions, such as polyols, feel modifiers, emulsifying stabilizers, ion chelating agents, disinfectants, pH modifiers, antioxidants, alcohols, plant extracts, fragrances, feel modifiers, emollients, etc.

[0049] The amounts of the aforementioned ingredients are not particularly limited and can be easily selected by a person skilled in the art within a range that does not impair the purpose and effects of the present invention.

[0050]

[0051] The cosmetic composition according to the present invention can provide a cooling sensation when applied to the skin and can temporarily reduce skin temperature. Additionally, it can provide a unique sensation of melting smoothly upon application to the skin, and can provide a refreshing moisturizing sensation that bursts like water upon application. Due to these characteristics, the cosmetic composition of the present invention can be particularly useful during the summer or in situations where skin soothing is required.

[0052] The cosmetic composition according to the present invention can be manufactured into various cosmetic products capable of providing a cooling sensation and a moisturizing sensation. For example, it can be manufactured into one or more formulations selected from the group consisting of massage cream, nourishing cream, moisture cream, hand cream, foundation, and cleansing cream, but is not limited thereto.

[0053] The cosmetic composition of the present invention may be provided in formulations commonly manufactured in the art. For example, it may be formulated into emulsion formulations of the type of oil in water (O / W), water in oil (W / O), or water in oil in water (W / O / W). However, it is not limited thereto, and the composition may also be provided in various formulations such as solution, suspension, emulsion, solid, oil, powder, paste, or foam aerosol, mist, etc.

[0054]

[0055] In the following, examples and experimental examples are presented to further explain the present invention in more detail, but the present invention is not limited thereto.

[0056]

[0057] Experimental Example 1. Comparative experiment based on the presence or absence of sodium carbomer and polyglyceryl-3-methylglucose distearate

[0058] (1) Preparation of Examples and Comparative Examples

[0059] In order to confirm the effects of the combination of sodium carbomer and polyglyceryl-3-methylglucose distearate in the present invention, cosmetic compositions of Example 1 and Comparative Examples 1 and 2 according to the present invention were prepared using the components listed in Table 1 below. Specifically, the cosmetic composition of Example 1 was prepared using sodium carbomer as a thickening agent and polyglyceryl-3-methylglucose distearate as an emulsifier, and the cosmetic composition of Comparative Examples was prepared by excluding one of the sodium carbomer and polyglyceryl-3-methylglucose distearate components. In Table 1 below, the unit of the content of each component is weight%.

[0060]

[0061]

[0062] The specific manufacturing method is as follows. A humectant and a preservative were added to purified water, and then sodium carbomer was added in small amounts and dispersed. The mixture was then stirred with a HOMOMIXER for 10 minutes to disperse the mixture, and then heated to 80°C to prepare a first aqueous mixture. The oil phase was heated to 78°C to dissolve the mixture, and then the oil phase was slowly added to the first mixture. The mixture was then stirred with a HOMOMIXER at 78°C for 5 minutes to disperse the mixture, and then cooled to 35°C to complete the examples and comparative examples.

[0063]

[0064] (2) Formulation stability evaluation

[0065] The formulation stability was evaluated by visually observing whether a formulation was formed in which the cosmetic compositions prepared according to Example 1 and Comparative Examples 1 and 2 were uniformly mixed.

[0066] Stability was evaluated as O when the liquid phase of the above cosmetic composition did not separate and the sodium carbomer was evenly dispersed to form a stable formulation, and stability was evaluated as X when the hardness of the composition was high or the liquid phase separated. The evaluation results are shown in Table 2 below. In addition, photographs of the cosmetic composition of Example 1 and photographs of the cosmetic compositions of Comparative Examples 1 and 2 are shown in Figure 1.

[0067]

[0068] (3) Spreadability evaluation

[0069] For the evaluation of spreadability, specifically, when the cosmetic composition was applied to the skin, it was rated as O if it burst open like water and was full of refreshing moisture; it was rated as X if the formulation was watery or had low turbidity, if it was stiff and difficult to apply to the skin, or if it felt somewhat sticky or greasy after application. The evaluation results are shown in Table 2 below.

[0070]

[0071]

[0072] According to Table 2 and Figure 1 above, in the case of Example 1, which was prepared by adding sodium carbomer and polyglyceryl-3-methylglucose distearate together, a stable formulation was formed, and a fresh, moisturizing spreadability was confirmed upon application to the skin. On the other hand, in the case of Comparative Example 1, which used only polyglyceryl-3-methylglucose distearate among the two ingredients, it was confirmed that the liquid phase of the composition separated and a stable formulation was not formed, making it impossible to measure spreadability. Furthermore, the composition of Comparative Example 2, which used only sodium carbomer among the two ingredients, formed a thin formulation and did not exhibit moisturizing spreadability.

[0073]

[0074] (4) Cooling and moisturizing effects

[0075] In order to evaluate the cooling and moisturizing effects of the cosmetic composition prepared according to Example 1 and Comparative Example 2 above, skin temperature, water retention, and transepidermal water loss were measured before and after a test of applying the cosmetic composition to the skin.

[0076] After cleansing the test area with a designated foam cleanser in a constant temperature and humidity room, the moisturizing, cooling, and moisturizing effects on the skin were measured. Specifically, square sections measuring 2x2 cm were designated as the test area (application area) and the non-application area on both forearms at intervals of at least 2 cm. The cosmetic compositions prepared according to Example 1 and Comparative Example 2 were dispensed at a dose of 2 mg / cm² each and spread evenly along the skin texture of the test area. After allowing them to absorb for 20 minutes, the changes in skin temperature, water retention, and transepidermal water loss (TEWL) before and after the test were measured. Skin temperature, water retention, and transepidermal water loss were measured repeatedly before and after the test, and the results are shown in Table 3.

[0077]

[0078]

[0079] According to Table 3 above, it was confirmed that the cosmetic composition of Example 1, prepared by adding sodium carbomer and polyglyceryl-3-methylglucose distearate together, showed improved transdermal water loss and immediate skin moisturizing effects compared to Comparative Example 2, which does not contain polyglyceryl-3-methylglucose distearate.

[0080] Therefore, it was confirmed that using sodium carbomer and polyglyceryl-3-methylglucose distearate together is an important composition that provides excellent cooling sensation with a refreshing spreadability and immediate skin moisturizing effect.

[0081]

[0082] Experimental Example 2. Comparative experiment based on sodium carbomer and polyglyceryl-3-methylglucose distearate content

[0083] To investigate the effects of sodium carbomer and polyglyceryl-3-methylglucose distearate content on the formulation and skin improvement effects of cosmetic compositions, cosmetic compositions of Examples and Comparative Examples were prepared by varying the added amounts of sodium carbomer and polyglyceryl-3-methylglucose distearate, and then the formulation stability, spreadability, and efficacy of the compositions were evaluated. The specific manufacturing method is as follows.

[0084]

[0085] (1) Preparation of Examples and Comparative Examples

[0086] To evaluate the efficacy according to the content of sodium carbomer and polyglyceryl-3-methylglucose distearate, cosmetic compositions of Examples 2 to 5 and Comparative Examples 3 to 9 were prepared by varying the content of sodium carbomer and polyglyceryl-3-methylglucose distearate based on Example 1, as described in Table 3. The specific manufacturing method is the same as in Experimental Example 1, and the remaining components and their content, excluding sodium carbomer and polyglyceryl-3-methylglucose distearate, are the same as in Example 1. The unit of the component content in Table 4 below is weight%. Here, the weight ratio of sodium carbomer (A) and polyglyceryl-3-methylglucose distearate (B) was calculated and listed in Table 4.

[0087]

[0088]

[0089] (2) Formulation stability evaluation

[0090] For the cosmetic compositions prepared according to Examples 2 to 5 and Comparative Examples 3 to 9, formulation stability evaluation was conducted in the same manner as performed in Experimental Example 1. The evaluation results are summarized in Table 5 below. In addition, photographs of the cosmetic compositions of Examples 2 to 5 and Comparative Examples 3 to 9 are shown in Figures 2 and 3.

[0091]

[0092] (3) Spreadability evaluation

[0093] For the cosmetic compositions prepared according to Examples 2 to 5 and Comparative Examples 3 to 9, spreadability was evaluated in the same manner as performed in Experimental Example 1. The evaluation results are summarized in Table 5 below.

[0094]

[0095]

[0096] According to Table 5 and Figures 2 and 3 above, in the case of Examples 2 to 5, which were prepared by adding sodium carbomer and polyglyceryl-3-methylglucose distearate together in an appropriate content ratio, it was confirmed that the formulation was stably formed and that when applied to the skin, a moist and hydrating spreadability was observed.

[0097] Meanwhile, it was confirmed that Comparative Examples 3 to 5, which contain a small amount or an excess amount of sodium carbomer compared to the Examples, did not form a stable formulation of the composition. In particular, Comparative Example 3, in which a small amount of sodium carbomer was added, showed separation of the liquid phase, and it was confirmed that the compositions of Comparative Examples 4 and 5 formed a thick texture due to the excess amount of sodium carbomer added, making it difficult to apply to the skin.

[0098] In addition, Comparative Examples 6 and 7, in which a small amount of polyglyceryl-3-methylglucose distearate was added compared to the examples, formed a thin formulation composition and did not provide a moisturizing sensation, while Comparative Examples 8 and 9, in which an excessive amount of polyglyceryl-3-methylglucose distearate was added, formed a high-hardness formulation composition and provided a stiff and slippery sensation when applied to the skin.

[0099]

[0100] (4) Evaluation of cooling and moisturizing effects

[0101] For the cosmetic compositions prepared according to Examples 2 to 4 and Comparative Examples 6 to 7, tests were conducted in the same manner as performed in Experimental Example 1, and changes in skin temperature, water retention, and transepidermal water loss (TEWL) before and after the test were measured, respectively. The evaluation results are summarized in Table 6 below.

[0102]

[0103]

[0104] According to Table 6 above, it was confirmed that the cosmetic compositions of Examples 2 to 4, prepared by adding sodium carbomer and polyglyceryl-3-methylglucose distearate in appropriate amounts, reduced transdermal moisture loss before and after application and had an excellent immediate skin moisturizing effect.

[0105] Meanwhile, it was confirmed that Comparative Examples 6 and 7, in which a small amount of polyglyceryl-3-methylglucose distearate was added compared to the example, showed a lower efficacy in reducing transdermal water loss after application to the skin.

[0106] Therefore, it was confirmed that including sodium carbomer and polyglyceryl-3-methylglucose distearate in appropriate amounts, respectively, is an important component in implementing a cosmetic composition with excellent skin moisturizing effects.

[0107]

[0108] Experimental Example 3. Comparative experiment according to sodium carbomer, polyglyceryl-3-methylglucose distearate, and oil content

[0109] To investigate the effects of the content of sodium carbomer, polyglyceryl-3-methylglucose distearate, and oil on the formulation of a cosmetic composition, cosmetic compositions of comparative examples were prepared by varying the added amounts of sodium carbomer, polyglyceryl-3-methylglucose distearate, and oil, and then the formulation stability and spreadability of the compositions were evaluated. The specific manufacturing method is as follows.

[0110]

[0111] (1) Preparation of Examples and Comparative Examples

[0112] To evaluate the efficacy according to the content of sodium carbomer, polyglyceryl-3-methylglucose distearate, and oil, cosmetic compositions of Comparative Examples 10 to 11 were prepared by varying the content of oil (dicaprylyl ether and jojoba seed oil) based on Example 1, as described in Table 7. The specific manufacturing method is the same as in Experimental Example 1, and the remaining components and their contents, excluding the oil, are the same as in Example 1. The unit of the component contents in Table 7 below is weight%. Here, the weight ratios of sodium carbomer (A), polyglyceryl-3-methylglucose distearate (B), and oil (C) were calculated and listed in Table 7.

[0113]

[0114] (2) Formulation stability evaluation

[0115] For the cosmetic compositions prepared according to Comparative Examples 10 and 11, formulation stability was evaluated in the same manner as performed in Experimental Example 1. The evaluation results are summarized in Table 8 below. In addition, photographs of the cosmetic compositions of Comparative Examples 10 and 11 are shown in Figure 4.

[0116]

[0117] (3) Spreadability evaluation

[0118] For the cosmetic compositions prepared according to Comparative Examples 10 to 11, spreadability was evaluated in the same manner as performed in Experimental Example 1. The evaluation results are summarized in Table 8 below.

[0119]

[0120]

[0121] According to Table 8 above, Comparative Example 10 formed a somewhat sticky formulation when applied to the skin as a transparent essence due to the small amount of oil content. In addition, Comparative Example 11 did not form a stable cosmetic composition because the oil layer separated due to the excessive amount of oil components. Therefore, it was confirmed that including sodium carbomer, polyglyceryl-3-methylglucose distearate, and oil in appropriate amounts or ratios is an important component for realizing a cosmetic composition with excellent formulation stability and cooling sensation.

[0122]
