Description

Transparent spray type Sun Screening Cosmetic composition by Inorganic UV Filter}

The present invention relates to a transparent spray-type sunscreen cosmetic composition using an organic sunscreen, and more specifically, to a transparent sunscreen cosmetic composition for spraying containing an organic sunscreen, ethanol, oil and purified water.

Recently, many studies have been conducted on the effect of ultraviolet rays on the human body as the amount of ultraviolet rays reaching the surface has increased due to the destruction of the ozone layer due to environmental pollution. The most representative one relates to skin aging caused by continuous exposure to ultraviolet rays.

As a method for delaying the skin aging phenomenon as described above, primarily, there is a method of reducing skin penetration of ultraviolet rays by using a sunscreen agent. In this regard, a lot of research is currently being conducted on a UV-blocking cosmetic composition for protecting the skin from ultraviolet rays (especially UV-A, B).

Sunscreens currently used in the cosmetic industry can be largely divided into inorganic sunscreens and organic sunscreens. Inorganic sunscreens are substances that are not absorbed by the skin and act only on the surface and have physical properties that reflect and disperse ultraviolet rays. Inorganic sunscreen has a high refractive index, so it has a great effect of scattering ultraviolet rays, but when applied to the skin, it is not refreshing due to a damp feeling, causing discomfort. Also do. Organic sunscreen refers to a material that exhibits a blocking effect by absorbing ultraviolet rays by trapping sunlight energy in a molecule. Unlike inorganic sunscreens, it does not have white turbidity, has good application properties, and has low fat content.

In general, most of the products exhibiting UV protection effect contain inorganic or organic UV protection agents, and many products are made into lotions or cream formulations by dispersing or emulsifying them evenly. In addition, there are products that contain gas in the contents and are sprayed by gas. However, these formulations are not suitable for use on sweaty or wet skin. For example, Korean Patent Registration No. 10-1002866 has a high UV blocking index in the form of a water-in-oil emulsion containing an organic UV blocker and an inorganic UV blocker. There is a phenomenon of losing or being pushed. In addition, Korean Patent Registration No. 10-0678790 is an oil-in-water type emulsified cosmetic composition, which has a UV protection function, but cannot be used due to emulsification when applied to wet skin.

Spray-type sunscreen products are mainly used for body because the contents are sprayed in the form of a fine spray and can be easily spread over a large area of skin. However, the use of inorganic sunscreens was limited because the valve was clogged due to powder agglomeration of inorganic sunscreens, and the use of inorganic sunscreens was limited, and it was difficult to expect a high sunscreen effect. So, there has been a lot of effort to increase the UV protection index by using powders such as butyl octyl salicylate, film former, and silica as a UV protection booster, but the UV protection index was not as high as the use of inorganic UV protection agents. As a result of clogging the valve, it was not possible to use a large amount of inorganic sunscreen, so it was difficult to expect a spray type with a UV protection index of SPF 50 and UVA protection rating of PA+++ or higher like a regular cream or lotion type.

In addition, Korean Patent Application Laid-Open No. 10-2013-0048886 is a spray-type formulation that has a high blocking ultraviolet ray index by applying an inorganic ultraviolet ray blocking agent, or when spraying on wet skin, lumping or clouding is severe. It was difficult to expect a spray-type formulation with SPF50+ and PA+++, which is excellent in convenience and can be used in any situation such as wet or dry skin without clouding.

Accordingly, as a result of the inventors' intensive research efforts to overcome the problems of the prior art, in the case of a sunscreen for a spray containing an organic sunscreen, an sunscreen for a spray containing ethanol, oil and purified water, UVB It was confirmed that the blocking index was higher than SPF50 and the UVA blocking grade was PA+++ while maintaining the cooling and makeup fixer function, and at the same time, there was no white turbidity and can be used on dry and wet skin, and the present invention was completed.

Therefore, the main object of the present invention is to provide a transparent spray-type sunscreen cosmetic composition using an organic sunscreen agent that has cooling and makeup fixer functions, does not have white turbidity, and can be used on wet skin.

According to one aspect of the present invention, the present invention provides a transparent sunscreen cosmetic composition for spray containing organic sunscreen, ethanol, oil and purified water.

In the present invention, the cosmetic composition is characterized in that the sun protection index is at least SPF 50 and the sun protection grade A is PA+++.

According to an embodiment of the present invention, as a result of measuring the UV protection index (SPF) and the UV A blocking grade (PA) of the spray sunscreen cosmetic composition (Examples 1 to 4) containing the cosmetic composition, both UV rays The blocking index was above SPF 50 and the UV A blocking grade was PA+++. From these results, it can be seen that the transparent spray sunscreen cosmetic composition of the present invention is very effective in sunscreen.

In the present invention, the cosmetic composition is characterized in that it comprises 5 to 50% by weight of an organic sunscreen, 1 to 60% by weight of ethanol, 1 to 30% by weight of oil, and 1 to 30% by weight of purified water.

In the composition of the present invention, the maintenance sunscreen is contained in an amount of 5 to 50% by weight, and if it is contained less than 5% by weight, a high sunscreen cannot be expected, and if it exceeds 50% by weight, the feeling of use and skin safety are deteriorated .

In the composition of the present invention, ethanol can improve a feeling of use, a feeling of cooling, and increase the solubility of raw materials, and in particular, improve the solubility of a sunscreen agent to make a transparent formulation. In order to achieve the above effect, ethanol is contained in an amount of 1 to 60% by weight, and cooling feeling and solubility improvement cannot be expected when it is less than 1% by weight, and when it exceeds 60% by weight, skin safety and odor are deteriorated.

According to the present invention, while increasing the amount of ethanol to 50% by weight, ethanol replaces the role of a surfactant and improves the clouding phenomenon, which is a disadvantage that occurs when the surfactant is contained, while making it usable for wet skin and increasing the cooling effect.

In the composition of the present invention, the oil component can increase the solubility and feeling of use of the sunscreen agent, and particularly has an effect of improving stickiness. In order to achieve the above effect, the oil component is contained in an amount of 1 to 30% by weight, and when less than 1% by weight, solubility and feeling of use cannot be improved, and when it exceeds 30% by weight, the feeling of use is deteriorated.

In the composition of the present invention, purified water was used to dissolve the sunscreen and give a feeling of moisture, and it is contained in an amount of 1 to 30% by weight of purified water, and when less than 1% by weight, solubility and moisture cannot be expected, and 30% by weight If it exceeds, the stability of the formulation deteriorates.

In the present invention, the organic sunscreen agent is homosalate, ethylhexyl salicylate, phenylbenzimidazole sulfonic acid, octocrylene, ethylhexylmethoxycinnamate, ethylhexyl palmitate, butylmethoxydibenzoylmethane, It is characterized in that at least one selected from the group consisting of bis-ethylhexyloxyphenol methoxyphenyltriazine.

In the present invention, the oil is a hydrocarbon-based oil including squalane or mineral oil; Ester oils including isopropyl palmitate, 2-octyldodecylmyristate, isopropylmyristerite, C12-15 alkylbenzoate, dicaprylyl carbonate or butyloctyl salicylate; Vegetable oils including castor oil, olive oil or jojoba oil; And 　 characterized in that at least one is selected from the group consisting of a silicone oil containing cyclomethicone or dimethicone.

In addition, the composition of the present invention optionally contains components known in the art to which the present invention pertains as conventional optional components for maintaining basic physical properties and quality, for example, ethylene diamine tetraacetate (EDTA), moisturizer, fatty substance, wetting agent. Ingredients commonly used in the manufacture of sunscreens, such as substances, silicones, oils, flavors, preservatives, transparent agents (sugar, alcohol), vitamins, proteins, and pigments, may be further included.

In addition, the composition of the present invention may include antioxidants, skin conditioning ingredients, pH adjusting ingredients, skin protection ingredients, etc. in addition to the above ingredients.

In the present invention, as the aerosol propellant, a liquefied gas commonly used in an aerosol container may be selected and used, preferably liquefied petroleum gas (LPG), propane, n-butane, isobutane, dimethyl ether, nitrogen and One or more selected from the group consisting of tetrafluoropropene may be mixed and used.

In the composition of the present invention, the amount of the propellant may be included in an amount of 10 to 90% by weight, preferably 40 to 60% by weight, based on the total weight of the composition. If it is less than 10% by weight, the desired effect cannot be obtained, and if it exceeds 90% by weight, the spraying pressure is too strong, which causes frostbite and content to be blown, resulting in poor usability.

In the present invention, the cosmetic composition is characterized in that it does not contain a surfactant.

According to an embodiment of the present invention, in the case of the spray sunscreen (Comparative Example 4 and Comparative Example 5) to which an organic or organic/inorganic sunscreen containing a surfactant was applied, a cloudiness phenomenon appeared and it was difficult to use it on wet skin (Fig. 2 and 3), in the case of spray sunscreens (Examples 1 to 4) to which an organic sunscreen containing no surfactant was applied, not only did not have a white cloudiness, but could also be used on wet skin (FIG. 1). From these results, it can be seen that if the surfactant is not included, the cloudiness phenomenon does not appear, and even if a sunscreen for spraying without the cloudiness phenomenon is used on the face, it does not get on the hair or clothes, so it is convenient to use.

In the present invention, the cosmetic composition is characterized in that it has a cooling function and a makeup fixer function.

According to an embodiment of the present invention, it was confirmed that the sunscreen without ethanol had almost no cooling effect, but when the sunscreen for spraying of the present invention was used, there was a cooling effect. In addition, in the case of Comparative Examples 1 to 3, it was difficult to measure the makeup fixer function itself due to the phenomenon of white cloudiness and the appearance, and in the case of Comparative Examples 4 and 5, there was a slight makeup fixer effect, but the makeup fixer effect after a long time (12 hours) Was not maintained, and it was inconvenient to use due to the phenomenon of getting on the head and clothes when applied to the face due to a cloudy phenomenon. On the other hand, the composition of the present invention was sprayed in a transparent state when applying the sunscreen for spray of the present invention to the face after makeup, so that there was no phenomenon of cloudiness and appearance, and the makeup fixer effect was maintained even after a long time (12 hours). From these results, since the spray sunscreen cosmetic composition (Examples 1 to 4) of the present invention does not have a cloudiness phenomenon, it has the advantage that it is easy to use because it does not smear on the hair and clothes when used on the face. It can be seen that it is excellent in the effect (Experimental Example 2) and the makeup fixer effect (Experimental Example 3) that maintains makeup, and is suitable as a transparent sunscreen cosmetic composition for spraying.

In the present invention, the cosmetic composition is characterized in that there is no cloudiness.

According to an embodiment of the present invention, in the case of a sunscreen for spray containing a surfactant (Comparative Example 4 and Comparative Example 5), a cloudiness phenomenon appeared and it was difficult to use it on wet skin (Figs. 2 and 3), but the interface of the present invention In the case of spray sunscreens (Examples 1 to 4) that did not contain an active agent, not only did they cause clouding, but they could also be used on wet skin (FIG. 1). From these results, it can be seen that in the case of the spray sunscreen cosmetic composition of the present invention, it is suitable as a transparent sunscreen cosmetic composition for spraying because there is no cloudiness phenomenon and thus it can be used on the face as there is no phenomenon on the head and clothes. have.

In the present invention, the cosmetic composition is characterized in that it can be used for dry and wet skin.

As described above, in the case of using the sunscreen for spray containing the transparent spray-type sunscreen cosmetic composition provided in the present invention, the UVB blocking index is higher than SPF50, and the UVA blocking grade is PA+++ while maintaining the cloudiness phenomenon. Because of this, it can be used effectively on wet or dry skin. It provides excellent spraying power and has a cooling effect and makeup fixer function. Therefore, it is suitable for use in outdoor sports or daily use.

I did.

Experimental example One : Feeling of use And usability of wet skin

The feeling of using the sunscreens prepared according to Examples 1 to 4 and Comparative Examples 1 to 5 and the feeling of using wet skin were tested.

As a result, as can be seen in FIG. 1, Examples 1 to 4 prepared by applying only an organic UV blocker without containing a surfactant were able to obtain a soft and refreshing composition without a clouding phenomenon. In particular, it was found that the compositions of Examples 1 and 2, which contain a lot of silicones and ethanol, can be applied to a refreshing feeling, cooling feeling, and wet skin.

On the other hand, in Comparative Example 1, an emulsification phenomenon occurred when applied to wet skin, so it was difficult to apply the sunscreen to the skin, and thus, the sunscreen effect could not be expected. In Comparative Examples 2 to 3, when applied to wet skin, a cloudiness phenomenon occurred and there was no feeling of use generally expected in cosmetics due to a stiff feeling of use, and it was difficult to expect a sunscreen effect because it was not applied softly and evenly. In addition, as shown in Fig. 2, in the case of an organic ultraviolet ray blocker for spray containing a surfactant (Comparative Example 5), a cloudiness phenomenon occurred and it was difficult to use on wet skin due to emulsification. In the case of the inorganic sunscreen (Comparative Example 4), a clouding phenomenon occurred.

Experimental example 2: UV protection index ( SPF ) Measurement, UVA blocking grade ( PA )Measure

The sunscreen effect of the sunscreen composition prepared according to Example 1 was tested. According to the'Ultraviolet Protection Functional Test Method' among the'Functional Cosmetics Standards and Test Methods' announced by the KFDA, the UV protection index is determined by attaching a transparent plastic tape (3M, USA) to a prepared cast, and then adding a 2 mg sample of the cosmetic composition. After coating at /cm2, the UV blocking effect was measured with a UV meter (SPF 290 Analyzer), and the UVA blocking grade PA was measured as an artificial ultraviolet ray emitter equipped with a 300W xenon arc lamp as a light source Multi-port Solar simulator 601-300W. (Solar Light, USA) was used, and the light intensity was measured using a 3D UV meter (Solar Light, USA), and the UV blocking index SPF and UV A for the compositions of Examples 1 to 4 and Comparative Examples 1 to 5 The blocking grade PA was measured. The result is as follows. The UV blocking index was summarized as the average value of the three experimental values, and the results are shown in Table 2 below.

Example 1 Example 2 Example 3 Example 4 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 SPF 53.4±±2.7 54.1±±2.4 54.0±±2.5 53.8±±2.6 52.5±±2.3 52.6±±2.4 42.8±±1.4 54.1±±1.5 52.8±±1.6 PA +++ +++ +++ +++ +++ +++ ++ +++ +++

As can be seen from the values shown in Table 2 above, it was confirmed that in the case of Comparative Example 3 in which the organic sunscreen was not used, the sunscreen index did not meet SPF50 and PA+++.

Experimental example 3: Cooling effect

The cooling effect of the sunscreen composition prepared according to Examples and Comparative Examples was tested. The cooling effect is determined by dividing the part used (test group) and the part not used (control) into the left and right sides of the face using a randomization method at the time point before product use, 10 minutes after infrared irradiation, and 1 minute after product use. Sprayed 2 to 3 times for 1 second at a distance of 15 cm to the test application site. The entire face was photographed using the infrared camera ThermacamTM PM360, an infrared camera that displays the temperature of each part as digital data and expresses it in different colors depending on the temperature. Reduction) effect was evaluated. In order to increase the skin temperature of the facial area, an infrared ray (IR) lamp (infralux-300, 220v/60hz) was used to maintain a distance of 40 cm, and then the entire face was irradiated for 10 minutes. The result is as follows. The cooling effect was summarized by the average value of the three experimental values, and the results are shown in Table 3 below.

Example 1 Example 2 Example 3 Example 4 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Temperature difference
(℃) 2.67±0.24 2.34±0.22 2.02±0.27 1.89±0.21 0.75±0.18 0.64±0.24 1.21±0.19 1.72±0.21 1.74±0.12

As can be seen from the values shown in Table 3, in the case of Comparative Examples 1 to 2 in which ethanol was not used, it was found that there was little cooling effect.

Example 4: makeup Fixer effect

The makeup fixer effect of the sunscreen composition prepared according to Examples and Comparative Examples was tested. For makeup persistence, 200 µl of foundation was applied to the entire face and then sprayed 3 to 4 times for 1 second at a distance of 30 cm. Before using the product, at 20 minutes, 4 hours, 8 hours, and 12 hours after using the product, the entire face was photographed using Facial stage® DM-3 (Moritex, Japan), a facial imaging device, and the captured UV image was taken. Image-pro® plus (Media- Cybernetics, USA) was used to analyze the mean value of the intensity (brightness) of the frontal cheeks. In the UV image, the area where the product is not applied appears bright and the intensity value is high, and the area where the product is applied appears dark, so the intensity value is low. The result is as follows. The makeup fixer effect was summarized as an average value of three measurements, and the results are shown in Table 4 and FIG. 3 below.

As shown in Table 4 above, in the case of Comparative Example 1, it was difficult to implement the makeup fixer function due to the phenomenon of the outer surface, and in the case of Comparative Example 2, the usability was not good due to the severe whiteness. However, there was a disadvantage that the formulation was not implemented due to severe white turbidity. It was difficult to measure the effect of a makeup fixer because of such a white turbidity phenomenon and problems in implementing the formulation. In the case of Comparative Example 4 and Comparative Example 5, when the sunscreen for spraying was applied to the face after makeup, there was a slight makeup fixer effect, but the makeup fixer effect was not maintained after a long time (12 hours), and it was applied to the face due to cloudiness. There was discomfort in use due to the phenomenon of getting on the hair and clothes.

On the other hand, the composition of the present invention was sprayed in a transparent state when applying the sunscreen for spraying of the present invention to the face after makeup, so there was no phenomenon of cloudiness and appearance, and the makeup fixer effect was maintained even after a long time (12 hours). In addition, the cooling effect of the skin was also excellent, and it was suitable for use on the face as there was no white haze phenomenon in usability.
