Description

Technical Field

[0001] The present invention relates to a cosmetic composition for transparent makeup and ultraviolet ray blocking.

Background Art

[0002] Ultraviolet rays (UV) are known to cause erythema, edema, freckles, etc. on the skin, and are confirmed as the main cause of skin cancer in extreme cases. Many studies have been conducted on various skin diseases caused by ultraviolet rays. Generally, ultraviolet rays are classified into a UV-C wavelength of 240 to 280 nm, a UV-B wavelength of 280 to 320 nm, and a UV-A wavelength of 320 to 400 nm according to their wavelengths. Among these, UV-C cannot reach the earth's surface while passing through the ozone layer and disappears, UV-B penetrates to the epidermis of the skin and causes erythema, freckles, edema, etc., and UV-A penetrates to the dermis of the skin and induces skin aging and skin irritation such as promoting wrinkle formation and melanin formation, or induces skin cancer. Recently, as the amount of ultraviolet ray irradiation on the earth's surface increases due to the destruction of the ozone layer, the market for products mainly aimed at blocking ultraviolet rays has been growing significantly every year, and consumers' needs for cosmetic compositions for blocking ultraviolet rays over the entire wavelength range tend to increase.

[0003] Generally, cosmetic compositions for UV protection have been proposed in two types: W / O type (water-in-oil type) with oil as the outer phase, and O / W type (oil-in-water type) with a water phase as the outer phase. While O / W type products have the advantage of a smoother feel when applied to the skin compared to W / O type products, they still suffer from the disadvantage of being easily washed away by sweat and water, despite ongoing research to improve water resistance, resulting in significantly inferior UV protection duration. On the other hand, W / O type products have superior durability compared to O / W type products, but they have the disadvantage of a heavy, sticky feel, which is not unrelated to the high viscosity of typical W / O type products. Furthermore, W / O type products are manufactured with a high viscosity by increasing the proportion of the water phase (the inner phase) to adjust the feel to be lighter, resulting in a disadvantage of reduced emulsion stability compared to O / W type products. Conversely, W / O type products with low viscosity have the problem of reduced product stability due to separation of the internal aqueous phase and the external oil phase during long-term storage in the container during distribution. Therefore, viscosity is increased to improve stability, but this leads to problems such as a heavy and sticky feel during use. Thus, research to solve the aforementioned problems is still necessary.

[0004] [Patent Document 1] Korean Patent Publication No. 10-2013-0102622 [Overview of the project] [Problems that the invention aims to solve]

[0005] One embodiment aims to provide a cosmetic composition that contains bis-ethylhexyloxyphenol methoxyphenyl triazine, yet possesses excellent UV blocking efficacy and a smooth, light feel. [Means for solving the problem]

[0006] According to one embodiment, a water-saturated (W / S) type cosmetic composition is provided, comprising an aqueous phase and an oil phase, wherein the oil phase contains bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, drometrizole trisiloxane, polar oil, and silicone-based oil. [Effects of the Invention]

[0007] One embodiment provides a water-resistant cosmetic composition for UV protection and translucent makeup with improved UV blocking effect by improving the solubility and dosage form stabilization issues of bis-ethylhexyloxyphenol methoxyphenyl triazine. [Brief explanation of the drawing]

[Figure 6] This image shows the presence or absence of precipitation in the cosmetic composition according to Comparative Example 3, as observed using a polarizing microscope. [Figure 7] This image shows the presence or absence of precipitation in the cosmetic composition according to Comparative Example 4, as observed using a polarizing microscope. [Modes for carrying out the invention]

[0009] The embodiments of the present invention will be described below in detail so that they can be easily implemented by a person with ordinary skill in the art to which the present invention pertains. However, the present invention can be embodied in a variety of different forms and is not limited to the embodiments described herein.

[0010] The terms used herein are for illustrative purposes only and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise.

[0011] Here, terms such as “include,” “equip,” or “possess” are intended to specify the existence of the implemented features, figures, stages, components, or combinations thereof, and should be understood not to preemptively exclude the existence or possibility of adding one or more other features, figures, stages, components, or combinations thereof.

[0012] Here, "or" is not interpreted as having an exclusive meaning; for example, "A or B" is interpreted as including A, B, A+B, etc.

[0013] A cosmetic composition according to one embodiment is a water-soluble (W / S) type cosmetic composition comprising an aqueous phase and an oil phase, wherein the oil phase comprises bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, drometrizole trisiloxane, polar oil, and silicone oil.

[0014] Another chemical name for the aforementioned bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) is 2,4-bis[4-(2-ethylhexyloxy)-2-hydroxyphenyl]-6-(4-methoxyphenyl)-1,3,5-triazine, also known as bemotoridinol. The aforementioned bis-ethylhexyloxyphenol methoxyphenyl triazine is known as an organic ultraviolet blocking agent that can block both UV-A and UV-B simultaneously, but it has the problem of low solubility. Therefore, the present inventors have deepened their research to solve the problem of bis-ethylhexyloxyphenol methoxyphenyl triazine, which has a high ultraviolet blocking effect but is difficult to apply to various dosage forms due to its solubility, and to develop a method that can be applied to a variety of dosage forms.

[0015] As a result, by including bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, drometrizole trisiloxane, polar oil, and silicone oil in optimal amounts, we have confirmed that we can provide a water-in-silicone oil (W / S) type cosmetic composition that solves the aforementioned problems while simultaneously achieving a stable dosage form despite the silicone being the outer phase, and solving the problem of bis-ethylhexyloxyphenol methoxyphenyl triazine precipitation, thus completing the present invention.

[0016] The cosmetic composition according to one embodiment is of the W / S (Water in Silicon oil) type. The "W / S type" means an emulsion having an oil containing silicone oil as a main component as a continuous phase and a dispersed phase containing water therein. That is, the W / S type cosmetic composition means an emulsion in a state where an inner aqueous phase containing water is dispersed in an outer oil phase containing silicone oil. Although the W / S type cosmetic composition tends to have a higher preference due to its refreshing feeling of use, there was a drawback that it could not be applied to the W / S type cosmetic composition due to the very low solubility of bis-ethylhexyl oxy-phenol methoxyphenyl triazine in silicone oil. Therefore, the present invention provides bis-ethylhexyl oxy-phenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and droxmetrizole trisiloxane dissolved in a polar oil, so that bis-ethylhexyl oxy-phenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and droxmetrizole trisiloxane are mixed in the skin and applied to the skin without gaps, thereby maximizing the ultraviolet blocking power.

[0017] That is, in the form of a normal emulsifier, it is difficult to coexist simultaneously with a light and non-greasy feeling of use and a feeling of use that provides a residual feeling and thickness due to excellent adhesion. However, the W / S type cosmetic composition according to the present invention is a dosage form having an optimal formulation that can provide these feelings of use simultaneously, provides a feeling of use different from that of a normal emulsifier form, and can uniformly disperse bis-ethylhexyl oxy-phenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and droxmetrizole trisiloxane in the dosage form. Of course, it is possible to provide a W / S type cosmetic composition that can effectively scatter ultraviolet rays and give a SPF boosting effect.

[0018] The aforementioned diethylamino hydroxybenzoyl hexyl benzoate and drometrizole trisiloxane are among organic ultraviolet blocking agents, and diethylamino hydroxybenzoyl hexyl benzoate had the problem of precipitation upon reaction with bis-ethylhexyloxyphenol methoxyphenyl triazine. Therefore, dissolving diethylamino hydroxybenzoyl hexyl benzoate and bis-ethylhexyloxyphenol methoxyphenyl triazine in a polar oil and mixing this with silicone oil has the advantage of not causing precipitation in a W / S formulation.

[0019] The total weight of bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and drometrizole trisiloxane can be 0.1 to 8.0% by weight per 100% by weight of the entire cosmetic composition. If the total weight of bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and drometrizole trisiloxane is less than 0.1% by weight per 100% by weight of the entire cosmetic composition, the UV blocking effect is negligible. If it exceeds 8.0% by weight, the polar oil content becomes high, resulting in a sticky and heavy feel, making it unsuitable for the manufacture of compositions with a light feel such as W / S type, and precipitation is accelerated. Specifically, the cosmetic composition may contain, with weights of bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and drometrizole trisiloxane in amounts of 0.1% or more, 0.2% or more, 0.4% or more, 0.6% or more, 0.8% or more, 1.0% or more, 1.2% or more, 1.4% or more, 1.6% or more, 1.8% or more, 2.0% or more, 2.2% or more, 2.4% or more, 2.6% or more, 2.8% or more, 3.0% or more, 3.2% or more, 3.4% or more, 3.6% or more, or 3.8% or more, based on 100% of the total weight of the cosmetic composition. Furthermore, the cosmetic composition may contain the total weight of bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and drometrizole trisiloxane in amounts of 8.0% by weight or less, 7.8% by weight or less, 7.6% by weight or less, 7.4% by weight or less, 7.2% by weight or less, 7.0% by weight or less, 6.8% by weight or less, 6.6% by weight or less, 6.4% by weight or less, 6.2% by weight or less, 6.0% by weight or less, 5.8% by weight or less, 5.6% by weight or less, 5.4% by weight or less, 5.2% by weight or less, 5.0% by weight or less, 4.8% by weight or less, 4.6% by weight or less, 4.4% by weight or less, 4.2% by weight or less, or 4.0% by weight or less, based on 100% by weight of the total cosmetic composition.

[0020] As an example, the bis-ethylhexyl oxy-phenol methoxyphenyl triazine can be contained in an amount of 0.1 to 4.0% by weight based on 100% by weight of the whole cosmetic composition. When the bis-ethylhexyl oxy-phenol methoxyphenyl triazine is contained in an amount of less than 0.1% by weight based on 100% by weight of the whole cosmetic composition, the ultraviolet blocking effect is negligible. When it exceeds 4.0% by weight, the content of the polar oil becomes high, and a sticky and heavy feeling of use appears, which is not suitable for the production of a composition having a light feeling of use such as a W / S type. Specifically, the cosmetic composition can contain the bis-ethylhexyl oxy-phenol methoxyphenyl triazine in an amount of 0.1% by weight or more, 0.2% by weight or more, 0.4% by weight or more, 0.6% by weight or more, 0.8% by weight or more, 1.0% by weight or more, 1.2% by weight or more, 1.4% by weight or more, 1.6% by weight or more, 1.8% by weight or more, 2.0% by weight or more, 2.2% by weight or more, 2.4% by weight or more, 2.6% by weight or more, 2.8% by weight or more, 3.0% by weight or more, 3.2% by weight or more, 3.4% by weight or more, 3.6% by weight or more, or 3.8% by weight or more based on 100% by weight of the whole cosmetic composition. Also, the cosmetic composition can contain the bis-ethylhexyl oxy-phenol methoxyphenyl triazine in an amount of 4.0% by weight or less, 3.8% by weight or less, 3.6% by weight or less, 3.4% by weight or less, 3.2% by weight or less, 3.0% by weight or less, 2.8% by weight or less, 2.6% by weight or less, 2.4% by weight or less, 2.2% by weight or less, 2.0% by weight or less, 1.8% by weight or less, 1.6% by weight or less, 1.4% by weight or less, 1.2% by weight or less, 1.0% by weight or less, 0.8% by weight or less, 0.6% by weight or less, 0.3% by weight or less, or 0.2% by weight or less based on 100% by weight of the whole cosmetic composition.

[0021] As one example, the cosmetic composition may contain 0.1 to 4.0% by weight of the diethylamino hydroxybenzoyl hexyl benzoate based on 100% by weight of the entire cosmetic composition. If the diethylamino hydroxybenzoyl hexyl benzoate is contained in an amount of less than 0.1% by weight of the total cosmetic composition, the UV blocking effect is minimal, and if it exceeds 4.0% by weight, the polar oil content becomes high, resulting in a sticky and heavy feel, which is unsuitable for the manufacture of compositions that have a light feel, such as W / S type. Specifically, the cosmetic composition may contain diethylaminohydroxybenzoylhexylbenzoate in amounts of 0.1% or more, 0.2% or more, 0.4% or more, 0.6% or more, 0.8% or more, 1.0% or more, 1.2% or more, 1.4% or more, 1.6% or more, 1.8% or more, 2.0% or more, 2.2% or more, 2.4% or more, 2.6% or more, 2.8% or more, 3.0% or more, 3.2% or more, 3.4% or more, 3.6% or more, or 3.8% or more, based on 100% of the total weight of the cosmetic composition. Furthermore, the cosmetic composition may contain diethylamino hydroxybenzoylhexyl benzoate in amounts of 4.0% by weight or less, 3.8% by weight or less, 3.6% by weight or less, 3.4% by weight or less, 3.2% by weight or less, 3.0% by weight or less, 2.8% by weight or less, 2.6% by weight or less, 2.4% by weight or less, 2.2% by weight or less, 2.0% by weight or less, 1.8% by weight or less, 1.6% by weight or less, 1.4% by weight or less, 1.2% by weight or less, 1.0% by weight or less, 0.8% by weight or less, 0.6% by weight or less, 0.3% by weight or less, or 0.2% by weight or less, based on 100% by weight of the total cosmetic composition.

[0022] As an example, the bis-ethylhexyloxyphenol methoxyphenyl triazine and diethylamino hydroxybenzoyl hexyl benzoate can be included in a weight ratio of 1:1 to 1:5, for example, in a weight ratio of 1:1 to 1:4, 1:1 to 1:3, or 1:1 to 1:2.

[0023] As one example, the cosmetic composition may contain 0.1 to 2.0% by weight of drometrizole trisiloxane based on 100% by weight of the entire cosmetic composition. If the amount of drometrizole trisiloxane is less than 0.1% by weight of the total cosmetic composition, the UV blocking effect is minimal, and if it exceeds 2.0% by weight, the polar oil content becomes high, resulting in a sticky, heavy feel, which is unsuitable for the production of compositions that have a light feel, such as W / S type. Specifically, the cosmetic composition may contain drometrizole trisiloxane in amounts of 0.1% or more, 0.2% or more, 0.3% or more, 0.4% or more, 0.5% or more, 0.6% or more, 0.7% or more, 0.8% or more, 0.9% or more, 1.0% or more, 1.1% or more, 1.2% or more, 1.3% or more, 1.4% or more, 1.5% or more, 1.6% or more, 1.7% or more, 1.8% or more, or 1.9% or more, based on 100% of the total weight of the cosmetic composition. Furthermore, the cosmetic composition may contain drometrizole trisiloxane in amounts of 2.0% by weight or less, 1.9% by weight or less, 1.8% by weight or less, 1.7% by weight or less, 1.6% by weight or less, 1.5% by weight or less, 1.4% by weight or less, 1.3% by weight or less, 1.2% by weight or less, 1.1% by weight or less, 1.0% by weight or less, 0.9% by weight or less, 0.8% by weight or less, 0.7% by weight or less, 0.6% by weight or less, 0.5% by weight or less, 0.4% by weight or less, 0.3% by weight or less, or 0.2% by weight or less, based on 100% by weight of the total cosmetic composition.

[0024] In one embodiment, the cosmetic composition may further contain an organic UV-blocking agent, an inorganic UV-blocking agent, or a combination thereof, depending on the purpose. Specifically, as organic UV-blocking agents, octyl methoxycinnamate, octyl salicylate, octocrylene, butyl methoxydibenzoylmethane, oxybenzone, octyl triazone, menthyl anthranilate, 3,4-methylbenzylidene camphor, isoamyl-p-methoxycinnamate, methylenebisbenzotriazolyltetramethylbutylphenol, etc., can be used, and as inorganic UV-blocking agents, powders such as titanium dioxide, zinc oxide, and iron oxide can be used.

[0025] A W / S type cosmetic composition according to one embodiment of the present invention comprises a polar oil for dissolving bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and drometrizole trisiloxane.

[0026] As an example, the polar oil in which bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and drometrizole trisiloxane are dissolved can include any type of polar oil that can provide bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and drometrizole trisiloxane in a stable dissolved state without precipitation even during long-term storage. The polarity of an oil is determined by the presence, type, number, or structure of functional groups that each oil possesses. Generally, alcohols, esters, and vegetable oils with a linear structure and hydrophilic functional groups are classified as relatively polar oils. For example, the polar oil may include oils containing one or more polar active groups from among carboxyl groups (-COO), ketone groups (-CO), and hydroxyl groups (-OH). Specifically, the polar oil may be one of the following: butylene glycol dicaprylate* dicapriate, ethylhexyl salicylate, butyl octyl salicylate, ethylhexyl methoxycinnamate, homosalate, C12-15 alkyl benzoate, dibutyl adipate, dicaprylyl carbonate, caprylyl-caprylate, cococaprylate, octocrylene, propylheptyl caprylate, isopropyl palmitate, caprylic / capric triglycerides, and cocoglycerides. More specifically, the polar oil may contain butyl octyl salicylate and dibutyl adipate, and the oil exhibits high solubility in bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and drometrizole trisiloxane, while having a less heavy feel than other polar oils.

[0027] As an example, the polar oil can be contained in an amount of 1% to 20% by weight relative to 100% by weight of the entire cosmetic composition, for example, 2% to 19% by weight, 3% to 18% by weight, 4% to 17% by weight, 5% to 16% by weight, 6% to 15% by weight, 7% to 15% by weight, or more specifically, 8% to 15% by weight, but is not limited thereto.

[0028] A W / S type cosmetic composition according to one embodiment of the present invention may contain one or more silicone-based oils selected from dimethicone, dimethicone*trisiloxane, cyclomethicone, methyltrimethicone, phenyltrimethicone, polydimethylsiloxane, methylphenylpolysiloxane, methylcyclopolysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, tetradecamethylhexasiloxane, octamethyltrisiloxane, and the like. More specifically, the silicone-based oil may include dimethicone*trisiloxane and methyltrimethicone, and as one embodiment, the silicone-based oil may be included in an amount of 15% to 60% by weight, more specifically 15% to 50% by weight, and more specifically 20% to 40% by weight, based on 100% by weight of the entire cosmetic composition, but is not limited thereto.

[0029] Therefore, the total weight of the bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, drometrizole trisiloxane, and polar oil can be included in a weight ratio of 1:1 to 1:5, for example, in a weight ratio of 1:1 to 1:4, 1:1 to 1:3, or 1:1 to 1:2.

[0030] In a W / S type cosmetic composition according to one embodiment of the present invention, the cosmetic composition may further contain a silicone-based surfactant comprising one or more of polyethylene glycol (PEG), polypropylene glycol (PPG), and polyglyceryl groups. The cosmetic composition according to one embodiment of the present invention can use a PEG-added silicone-based surfactant. Examples of PEG-added silicone-based surfactants include PEG / PPG-18 / 18 Dimethicone (Cyclopentasiloxane and PEG / PPG-18 / 18 Dimethicone), PEG-30 Dipolyhydroxystearate, PEG-7 Dimethicone, PEG-10 Dimethicone, Cyclopentasiloxane / PEG.PPG-19.19 Dimethicone, Sorbitan Isostearate, Lauryl PEG.PPG-18.18 Methicone, and Cetyl PEG.PPG-10.1 Dimethicone. Examples include dimethicone, lauryl PEG-9 polydimethylsiloxyethyl dimethicone, and lauryl PEG-10 tris(Trimethylsiloxy)silylethyl dimethicone. In addition, the present invention may use one or more of the exemplified PEG-added silicone surfactants, but is not limited thereto. More specifically, the PEG-added silicone surfactant may be a nonionic surfactant with a hydrophilic-lipophilic group balance (HLB) of 1 to 6.As an example, the surfactant may be included in an amount of 0.01 to 10% by weight relative to the total weight of the cosmetic composition, specifically 1 to 8% by weight, and more specifically 3 to 6% by weight. If the amount is less than 0.01% by weight, the dispersibility of the UV-blocking agent will decrease, and if it exceeds 10% by weight, stickiness may be induced, hindering the smooth feeling of use.

[0031] For example, the cosmetic composition may contain the remaining amount of water.

[0032] The aqueous phase of a W / S type cosmetic composition according to one embodiment of the present invention may contain one or more of water and ethanol, and otherwise may contain all components that can normally be included in the aqueous phase.

[0033] The W / S type cosmetic composition according to one embodiment may contain, along with the active ingredient, other ingredients that can preferably enhance the main effect, within a range that does not impair the main effect. In addition to the active ingredient of the present invention, other ingredients can be appropriately selected and blended without difficulty by those skilled in the art, depending on the dosage form or intended use of the composition. Furthermore, as one embodiment, the cosmetic composition of the present invention may, along with the above ingredients, optionally contain other ingredients that are commonly blended in cosmetic compositions. Examples include humectants, emollients, thickeners, organic and inorganic pigments, organic powders, preservatives, bactericides, antioxidants, plant extracts, pH adjusters, alcohols, dyes, fragrances, blood circulation promoters, cooling agents, antiperspirants, and purified water. Other ingredients that may be included in the cosmetic composition of the present invention are not limited thereto, and the amount of the above ingredients can be within a range that does not impair the purpose and effect of the present invention.

[0034] A W / S type cosmetic composition according to one embodiment can be formulated into dosage forms containing a cosmetologically or dermatologically acceptable medium or base. It can be provided in all dosage forms suitable for topical application, for example, in the form of a solution, gel, solid, paste anhydrous product, emulsion obtained by dispersing an oil phase in an aqueous phase, suspension, microemulsion, microcapsule, fine granules or ionic (liposome) and nonionic vesicle dispersants, or in the form of a cream, skin, lotion, powder, ointment, spray or conceal stick. It can also be used in the form of a foam or in the form of an aerosol composition further containing a compressed propellant. These compositions can be manufactured by conventional methods of the art.

[0035] A W / S type cosmetic composition according to one embodiment may be used for UV protection.

[0036] The contents of the present invention will be described in more detail below through examples and comparative examples. These examples are provided solely for the purpose of understanding the contents of the present invention, and the scope of the present invention is not limited to these examples and test examples. Modifications, substitutions, and insertions that are commonly known in the industry are also permitted and are included within the scope of the present invention.

Specifically, the left and right forearms of each panel (5 men and 5 women) were washed with soap, and then the skin was adapted to a temperature of approximately 20°C and a humidity of approximately 40%. 4x3cm patches were applied to the left and right inner surfaces of the forearms. 2 A rectangular area was defined as the test site, and patches coated with each sample were attached to it. After 28 hours, the patches were removed, the first reading was taken 30 minutes later, and a second reading was taken after 96 hours. To investigate the intensity of skin irritation for each sample, a weighted value was assigned according to the degree of positive skin reaction to calculate the average skin reaction score, and the skin irritation of each sample was visually judged. The results are shown in Table 4 below. At this time, the judgment criteria were indicated as no irritation range, mild irritation: stable, moderate irritation, and strong irritation: unstable.

[0049] Evaluation Example 3: Durability To confirm the durability of the cosmetic compositions in the examples and comparative examples, a patch test was conducted. Specifically, after washing the left and right forearms of each panel (5 men and 5 women) with soap, 4x3cm patches were applied to the left and right inner surfaces of the forearms. 2 A rectangular area was defined as the test site, and patches coated with each sample were attached to it. After 6 hours, the patches were removed and the persistence was evaluated. The results are shown in Table 4 below, where the criteria for evaluation were: less than 40% persistence: poor, 60% or more persistence: good.

[0050] Evaluation Example 4: User Experience The sensory evaluation of the cosmetic compositions in the examples and comparative examples was based on the feeling of use during and after application. The sensory evaluation was conducted using a general questionnaire with 5 males and 5 females participating in the evaluation, and the results are shown in Table 4 below. The questionnaire was scored out of 10 points, with scores of 5 or less indicating dissatisfaction and scores above 5 indicating satisfaction.

[0051] [Table 4]

[0052] Referring to Table 4 and Figures 1-7, in the example where the W / S type cosmetic composition contains bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylamino hydroxybenzoyl hexyl benzoate, and drometrizole trisiloxane as UV-blocking agents, no precipitation was observed, confirming excellent stability, durability, and feel. In contrast, in Comparative Example 1, which contains only diethylamino hydroxybenzoyl hexyl benzoate as a UV-blocking agent; Comparative Example 2, which contains only bis-ethylhexyloxyphenol methoxyphenyl triazine; and Comparative Examples 3 and 4, which contain only bis-ethylhexyloxyphenol methoxyphenyl triazine and diethylamino hydroxybenzoyl hexyl benzoate, precipitation was observed, confirming poor stability, durability, and feel. Furthermore, in Comparative Example 5, which is an oil-in-water (O / W) type cosmetic composition, and Comparative Example 6, which is a water-in-oil (W / O) type cosmetic composition, poor durability and feel were also confirmed.

[0053] While preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto. Various modifications and improvements by those skilled in the art, utilizing the basic concepts defined in the claims, also fall within the scope of the present invention.
