Description

Technology Field

[0001] The present invention relates to a cosmetic composition comprising diisopropyl sebacate, and specifically, to a cosmetic composition capable of providing excellent cleansing efficacy and foam-forming ability through a combination of diisopropyl sebacate and a surfactant. Background Technology

[0002] In modern society, protecting the skin from ultraviolet (UV) rays is recognized as a critical task. It is known that prolonged exposure to UV-A and UV-B rays can cause various skin damages, including photoaging, pigmentation, and an increased risk of skin cancer. Consequently, consumers use sun care products as an essential measure to protect their skin from UV rays not only in daily life but also during outdoor activities, and the frequency of use and the importance of sun care products are steadily increasing.

[0003] Sun care products contain UV blockers to inhibit the penetration of ultraviolet rays; however, because these ingredients are highly oil-soluble and formulated to adhere closely to the skin, they tend to remain on the skin for a long time. Consequently, while they offer excellent UV protection, they are difficult to remove during the cleansing process. If sun care products are not completely removed from the skin surface, they can cause clogged pores, skin irritation, and skin troubles, which, if repeated over a long period, can have an adverse effect on skin health.

[0004] Diisopropyl sebacate is a synthetic ester oil of light low dibutyl adipate obtained by the esterification of sebacic acid and isopropyl alcohol, and has been used as a dispersion stabilizer and solubilizing agent for organic sunscreen ingredients.

[0005] However, as a result of repeated research on the effective cleansing of sun care products, the inventors confirmed that by including diisopropyl sebacate in a cleansing composition, beyond the conventional use of diisopropyl sebacate as a solubilizing agent, organic UV filters remaining on the skin can be dissolved and removed more easily.

[0023] 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.

[0025] According to an embodiment of the present invention, a cosmetic composition comprising diisopropyl sebacate and a surfactant is provided. The inventors have confirmed that when diisopropyl sebacate and a surfactant are optimally combined, it is possible to form a formulation with appropriate physical properties and achieve excellent cleansing efficacy.

[0026] In the present invention, “Diisopropyl Sebacate” refers to a diester obtained by the esterification reaction of sebacic acid with isopropyl alcohol, and generally serves to effectively dissolve and disperse oil-soluble sunscreens, organic pigments, and polymer components. In the cosmetic composition according to the present invention, diisopropyl sebacate has a high affinity for organic sunscreen components, and by effectively dissolving sunscreens and poorly soluble oil components, it can provide excellent cleansing efficacy.

[0027] According to an embodiment of the present invention, a cosmetic composition comprising diisopropyl sebacate may be provided. The diisopropyl sebacate may be included in an amount of 0.01 to 5 weight% based on the total weight of the cosmetic composition, specifically 0.1 to 3 weight%, and more specifically 0.5 to 1.5 weight%, but is not limited thereto. When the diisopropyl sebacate is included in the above amount, a formulation with appropriate physical properties and excellent cleansing efficacy may be provided. On the other hand, if the diisopropyl sebacate is included in a small amount or an excessive amount compared to the above amount, the cleansing effect may be significantly reduced.

[0028] In the present invention, the “surfactant” is a component having both hydrophilic and hydrophobic groups, capable of uniformly mixing or dispersing oil phase components and water phase components, and can be used in a cleansing cosmetic composition to effectively remove sebum, contaminants, makeup residues, and sunscreen components from the skin surface. The cosmetic composition according to the present invention may include one or more surfactant components selected from the group consisting of potassium cocoyl glycinate, potassium cocoyl taurate, sodium methyl cocoyl taurate, PEG-100 stearate, cocamidopropyl betaine, potassium cocoate, sodium cocoyl glycinate, sodium lauroyl glutamate, sorbeth-30 tetraoleate, and sorbitan sesquioleate as surfactant components that may be included together with diisopropyl sebacate.

[0029] In the present invention, “Potassium Cocoyl Glycinate” is an amino acid-based anionic surfactant that has excellent skin affinity and can provide soft foam formation and cleansing efficacy. In the cosmetic composition according to the present invention, the potassium cocoyl glycinate is combined with other surfactants including sodium methyl cocoyl taurate to provide a formulation with appropriate physical properties and excellent cleansing efficacy.

[0030] In the present invention, “Sodium Methyl Cocoyl Taurate” is an ingredient that provides cleansing power and foam-forming power. In the cosmetic composition according to the present invention, the sodium methyl cocoyl taurate is combined with other surfactants including potassium cocoyl glycinate to provide a formulation with appropriate physical properties and excellent cleansing efficacy.

[0031] In a cosmetic composition according to an embodiment of the present invention, the potassium cocoyl glycinate and sodium methyl cocoyl taurate may be included in a weight ratio of 1:0.4 to 3, but are not limited thereto. When the potassium cocoyl glycinate and sodium methyl cocoyl taurate are included in the composition in the above weight ratio, excellent foam-forming ability and high-temperature stability may be exhibited.

[0033] In the present invention, the term “acid component” refers to a component such as a fatty acid or a carboxylic acid that can impart cleansing power or emulsifying power, and the cleansing efficiency can be maximized by including it together with diisopropyl sebacate in the cosmetic composition of the present invention. The cosmetic composition according to the present invention may include three or more selected from the group consisting of myristic acid, lauric acid, palmitic acid, stearic acid, capric acid, caprylic acid, oleic acid, linoleic acid, salicylic acid, arachidic acid, behenic acid, and isostearic acid. When three or more of the acid components are combined in the cosmetic composition according to the present invention, a formulation with appropriate physical properties and excellent cleaning power can be provided, but when two or fewer of the acid components are included, problems with poor formulation and cleaning power may occur.

[0034] The above acid component may be included in a foam formulation cosmetic composition according to one embodiment of the present invention in an amount of 11 to 50 weight%, specifically 12 to 45 weight%, more specifically 13 to 40 weight% based on the total weight of the cosmetic composition, but is not limited thereto. When the above acid component is included in the above amount, it can provide a formulation with appropriate physical properties and excellent cleansing power. On the other hand, if the above acid component is included in a small amount less than the above amount, the foam-forming power may be low and the cleansing power and formulation may be poor, and if the above acid component is included in an excessive amount more than the above amount, a problem may occur in which formulation formation is impossible.

[0035] In the cosmetic composition according to the present invention, the diisopropyl sebacate and the acid component may be included in a weight ratio of 1:11 to 400, specifically 1:11 to 200, and more specifically 1:13 to 200, but are not limited thereto. When the diisopropyl sebacate and the acid component are included in the above weight ratio, a formulation with appropriate physical properties and excellent cleansing power can be provided. On the other hand, if the weight of the acid component relative to the weight of the diisopropyl sebacate is less than the above weight, the foam-forming power may be low and the cleansing power and formulation may be poor, and if the weight of the acid component relative to the weight of the diisopropyl sebacate is excessive compared to the above weight, a problem may occur in which formulation formation is impossible.

[0036] Specifically, in the present invention, “myristic acid” is an acid component capable of imparting cleansing efficacy, and in the cosmetic composition according to the embodiment of the present invention, it can form rich foam and effectively remove residue from the skin surface. When myristic acid is included as an acid component in the cosmetic composition of the present invention, the myristic acid may be included in an amount of 10 to 18 weight%, specifically 12 to 18 weight%, and more specifically 14 to 18 weight% based on the total weight of the cosmetic composition, but is not limited thereto. When the myristic acid is included in the above amount and the total acid content is included in the optimal amount described above, it is possible to form a formulation with appropriate physical properties and provide excellent cleansing power.

[0037] Specifically, in the present invention, “Lauric Acid” is an acid component that imparts cleansing efficacy; in the cosmetic composition according to the embodiment of the present invention, it provides an antibacterial effect and plays a role in removing sebum, and can maximize cleansing efficiency through combination with other acid components. When lauric acid is included as an acid component in the cosmetic composition of the present invention, the lauric acid may be included in an amount of 1 to 6 weight%, specifically 2 to 6 weight%, and more specifically 3 to 6 weight% based on the total weight of the cosmetic composition, but is not limited thereto. When the lauric acid is included in the above amount and the total acid content is included in the optimal amount described above, it is possible to form a formulation with appropriate physical properties and provide excellent cleansing power.

[0038] Specifically, in the present invention, “Palmitic Acid” is an acid component that provides foaming stability and cleaning assistance efficacy, and can contribute to the formation of rich foam in the cosmetic composition according to the embodiment of the present invention and can maximize cleaning efficiency through combination with other acid components. When palmitic acid is included as an acid component in the cosmetic composition of the present invention, the palmitic acid may be included in an amount of 1 to 6 weight%, specifically 2 to 6 weight%, and more specifically 3 to 6 weight% based on the total weight of the cosmetic composition, but is not limited thereto. When the palmitic acid is included in the above amount and the total acid content is included in the optimal amount described above, it is possible to form a formulation with appropriate physical properties and provide excellent cleaning power.

[0039] Specifically, in the present invention, “Stearic Acid” is an acid component that assists in viscosity control and cleansing efficacy. It plays a role in stabilizing the viscosity of the formulation in the cosmetic composition according to the embodiment of the present invention and can maximize cleansing efficacy through combination with other acid components. When Stearic Acid is included as an acid component in the cosmetic composition of the present invention, the Stearic Acid may be included in an amount of 1 to 10 weight%, specifically 1.5 to 6 weight%, and more specifically 2 to 4 weight% based on the total weight of the cosmetic composition, but is not limited thereto. When the Stearic Acid is included in the above amount and the total acid content is included in the optimal amount described above, it is possible to form a formulation with appropriate physical properties and provide excellent cleansing power.

[0041] The cosmetic composition according to the present invention may further include dibutyl adipate.

[0042] In the present invention, “Dibutyl Adipate” is an ester oil component that can be utilized as a solvent or a sensory enhancer, and can effectively dissolve poorly soluble components and provide a soft feel.

When the dibutyl adipate is included in the above amount, it can form a formulation with appropriate physical properties and provide excellent cleansing power.

[0044] In addition, the cosmetic composition of the present invention may be manufactured into one or more products selected from the group consisting of cleansing foam, cleansing oil, cleansing balm, cleansing lotion, cleansing cream, soap, hand cream, pack, and body cleanser, and in particular, may be manufactured in a cleansing foam formulation, but is not limited thereto.

[0045] In the present invention, the term “foam formulation” refers to a cosmetic composition in which a large amount of bubbles are formed using the foaming action of a surfactant; generally, the composition may be in a form that converts into foam upon contact with water or physical friction during cleansing. A cosmetic composition of foam formulation according to one embodiment of the present invention can gently remove impurities by having a bubble structure that spreads evenly on the skin surface, can provide a rich foaming sensation and excellent usability, and can contribute to protecting the skin barrier by reducing physical irritation through the buffering action of the bubbles.

[0046] In one embodiment, the cosmetic composition of the present invention may additionally include ingredients found in general cosmetic compositions, such as, for example, functional ingredients, solvents, antioxidants, skin conditioning agents, ion chelating agents, disinfectants, alcohols, plant extracts, fragrances, preservatives, moisturizers, thickeners and texture modifiers, sweeteners, etc. The amounts of the above-mentioned 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.

[0048] 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.

[0050] Experimental Example 1. Comparative experiment based on the inclusion and content of diisopropyl sebacate

[0051] (1) Preparation of Examples and Comparative Examples

[0052] In order to confirm the formulation and cleansing power of the composition according to the cosmetic composition of the present invention based on whether diisopropyl sebacate is included and its content, examples and comparative examples were prepared with the ingredients and content shown in Table 1 below. The content in Table 1 below is in weight%.

[0054]

[0055] The specific manufacturing method is as follows. The purified water and skin conditioning agent of Table 1 were sufficiently dispersed using an AGITATOR, and the surfactant of Table 1 was dissolved at 60–80°C, mixed with the purified water and skin conditioning agent portion, and then sufficiently dispersed. Subsequently, the pH adjuster of Table 1 was added and dispersed, and the antioxidant and metal ion chelating agent of Table 1 were added and dispersed to prepare the examples and comparative examples.

[0057] (2) Evaluation results

[0058] The formulation and cleaning power evaluations were conducted on the examples and comparative examples prepared with the ingredients and content shown in Table 1 above. The formulation evaluation was performed by visually checking the degree of foam formation and measuring the hardness of the formulation to confirm whether appropriate physical properties were formed. Specifically, the hardness was measured using a 20mm diameter pin of a CR-100 Rheo-Meter hardness tester under conditions of 0.1kg, 15mm, and 30cm / min.

[0059] The cleansing power was evaluated by applying sun care to the skin, applying each composition to the sun care, rolling it 30 times, and then rinsing it off with water to evaluate the cleansing rate and cleansing power. A photograph comparing and confirming the cleansing power of Examples 1 and 2 is shown in Figure 1. Additionally, a photograph comparing the foam formation and density of Example 1 and Comparative Example 1 using a foam scanner for 10 minutes under conditions of a sample concentration of 1%, a measurement volume of 20 mL, a flow rate of 0.3 L / min, and a foam generation time of 20 seconds is shown in Figure 2.

[0060]

[0061] According to Table 2 above, in the case of Comparative Examples 1 and 2, which do not contain diisopropyl sebacate or contain a small amount compared to the Examples, it can be seen that although formulations with appropriate physical properties were formed, the cleaning power was poor. On the other hand, in the case of Examples 1 to 3, as can be seen in Table 2 and Figure 1, it was confirmed that not only were formulations with appropriate physical properties formed, but the cleaning power was also excellent. In addition, according to Figure 2, it can be seen that the foam of Comparative Example 1 was formed relatively less densely and larger compared to Example 1, resulting in lower density.

[0062] Therefore, it was confirmed that when diisopropyl sebacate is included as in the example, a cosmetic composition having appropriate physical properties and excellent cleansing power can be provided.

[0064] Experimental Example 2. Comparative experiment based on the inclusion and content of surfactant components

[0065] (1) Preparation of Examples and Comparative Examples

[0066] To confirm the specificity of the surfactant component included in the cosmetic composition according to the present invention, examples and comparative examples were prepared with the components and amounts shown in Table 3 below. The specific preparation method is the same as that of Experimental Example 1 above. Comparative Examples 3 to 7 were prepared by excluding specific surfactant components or varying their amounts based on Example 1, while the remaining components and amounts are the same. The amounts in Table 3 below are in weight%.

[0068]

[0069] (2) Evaluation results

[0070] For the examples and comparative examples prepared with the ingredients and content shown in Table 3 above, the formulation and cleaning power were evaluated using the same method as in Experimental Example 1 above, and the observation results are shown in Table 4 below. In addition, the foam-forming ability was evaluated by visually observing the foam formation and foam density of each example and comparative example, and the results are shown in Table 4 below. A photograph comparing the foam densities of Example 1 and Comparative Example 3 is shown in Figure 2. Furthermore, to confirm the formulation stability of each example and comparative example at high temperatures, changes in the formulation were evaluated after storage at 40 °C and 50 °C for one month using an incubator. If the formulation was maintained stably without separation, increase in hardness, or precipitation, it was marked as 'O', and if the hardness increased significantly or the formulation separated, it was marked as 'X', as shown in Table 4 and Figure 3 below.

[0071]

[0072] As a result of the evaluation, as can be seen in Table 4 and Figure 3 above, Example 1, which contains potassium cocoyl glycinate, sodium methyl cocoyl taurate, and cocamidopropyl betaine, exhibited appropriate physical properties and foam formation, as well as excellent formulation stability at high temperatures. However, in the case of Comparative Example 3, which does not contain potassium cocoyl glycinate, sodium methyl cocoyl taurate, and cocamidopropyl betaine, it was confirmed that the foam-forming ability and density of the composition were significantly lower than those of the example, and the formulation stability at high temperatures was poor. In addition, in the case of Comparative Example 4, which does not contain sodium methyl cocoyl taurate and cocamidopropyl betaine, and Comparative Example 5, which does not contain potassium cocoyl glycinate and cocamidopropyl betaine, it was confirmed that foam formation and foam density were significantly reduced, and formulation stability at high temperatures was also reduced. In addition, in the case of Comparative Examples 6 and 7, in which the ratio of potassium cocoyl glycinate and sodium methyl cocoyl taurate was changed, it was confirmed that the foam density decreased and foam-forming ability was reduced compared to the example, and that high-temperature stability was poor.

[0074] Through this, it was confirmed that a cosmetic composition having appropriate physical properties and excellent cleansing power can be provided when the surfactant components potassium cocoyl glycinate, sodium methyl cocoyl taurate, and cocamidopropyl betaine are included together with diisopropyl sebacate as in the example.

[0076] Experimental Example 3. Comparative experiment according to acid component combination and content

[0077] (1) Preparation of Examples and Comparative Examples

[0078] To confirm the stability of the composition according to the combination and content of the acid components included in the cosmetic composition according to the present invention, cosmetic compositions according to the Examples and Comparative Examples were prepared with the components and content as shown in Table 5 below. The specific manufacturing method is the same as that of Experimental Example 1 above, and based on Example 1, only the content of each acid component was changed, while the remaining components and content are the same. The contents in Table 5 below are in weight%.

[0080]

[0081] (2) Evaluation of formulation and cleaning power

[0082] For the examples and comparative examples prepared with the ingredients and content as shown in Table 5 above, the formulation and cleaning power were evaluated using the same method as in Experimental Example 1 above. The observation results are shown in Table 6 below, and a photograph showing the observed formulation of each composition is shown in Figure 4.

[0083]

[0084] According to Table 6 above, in the case of Example 4, which contains three types of acid components, appropriate physical properties were formed and an excellent cleaning effect was confirmed, whereas in the case of Comparative Example 8, which contains only two types of acid components, formulation formation was impossible and consequently, cleaning power could not be confirmed. Additionally, in the case of Comparative Example 9, which has a small amount of acid components compared to the example, formulation formation was impossible and cleaning power could not be confirmed. Furthermore, in the case of Comparative Example 10, which has an excessive amount of acid components compared to the example, formulation formation was also impossible. On the other hand, in the case of Examples 5 and 6, which contain four types of acid components appropriately, although there were differences in hardness, it was confirmed that both achieved excellent cleaning power.

[0086] Accordingly, it was confirmed that a cosmetic composition having excellent cleansing power and a formulation having appropriate hardness can be provided when at least three types of acid components are included as in the example and included in an appropriate amount.

[0088] Foregoing, specific parts of the content of the present invention have been described in detail. It will be apparent to those skilled in the art that such specific descriptions are merely preferred embodiments and do not limit the scope of the present invention. Accordingly, the actual scope of the present invention is defined by the appended claims and their equivalents.
