Description

Cosmetic composition for UV protection {SUNSCREEN COSMETIC COMPOSITION}

The present invention relates to a cosmetic composition for sunscreen, and more specifically, by containing natural ingredients extracted from hot spring water, it exhibits a skin whitening effect by reducing the production of tyrosyanin and melanin, and has a high sunscreen effect even if it contains a small amount of organic sunscreen. It relates to a cosmetic composition suitable for application to solid cosmetic formulations such as sun sticks or sun balms.

Common sunscreens contain organic sunscreens along with inorganic sunscreens containing titanium dioxide. This is because the inorganic sunscreen mainly blocks ultraviolet A (UVA) rays, so an organic sunscreen must be used to block ultraviolet B (UVB) rays.

The organic sunscreen must meet the hazard standards according to the EWG (Environmental Working Group) rating, and the mixing limit is also strictly regulated by law. As there is a high possibility of harmful effects when used on the skin, the amount used is reduced as much as possible.

Cosmetic compositions for sunscreen that do not use organic sunscreens are being developed. For example, in Republic of Korea Patent No. 10-1972835, an inorganic sunscreen is used to reduce the content of ethylhexyl methoxycinnamate, an organic sunscreen. There is a known technology for surface treating the surface of phosphorus titanium dioxide with 2-ethylhexyloxide group. In addition, Republic of Korea Patent No. 10-2251306 discloses a cosmetic composition containing Lactobacillus plantarum culture extract that has the effect of improving skin wrinkles, whitening effect, and increasing moisture retention time, and Registered Patent No. 10 In No. 2087904, a cosmetic composition is known that contains bifidus extract, star anise extract, Virginia fern leaf extract, and Indian gooseberry fruit extract, thereby exhibiting skin wrinkle improvement effect, whitening effect, and increasing duration effect.

Such cosmetic compositions include BB cream, skin lotion, skin softener, skin toner, astringent, lotion, milk lotion, moisture lotion, nutritional lotion, massage cream, nutritional cream, UV protection cream, moisture cream, hand cream, foundation, essence, It is expected that it can be mixed and used in cosmetics such as nutritional essence, mask pack, soap, cleansing foam, cleansing lotion, cleansing cream, body lotion, and body cleanser. However, it can be mixed with sun stick or sun balm as a sunscreen and solid cosmetics. In this case, it was discovered that the natural extract was not mixed homogeneously and the organic ingredients contained in the sunscreen cream deteriorated the functionality of the cosmetic composition.

Even when looking at known technologies regarding sunscreen cosmetic compositions containing natural products, they are found to be insufficient to effectively block both UVA and UVB since they merely involve mixing natural products in appropriate ingredients and proportions and do not use organic or inorganic sunscreens ( Registered Patent No. 10-1463962, Registered Patent No. 10-1148978). In addition, in Republic of Korea Patent Publication No. 10-2022-0057361, a cosmetic composition for sunscreen is known that does not use an inorganic sunscreen but uses a polar oil containing an organic sunscreen and a sunscreen booster ingredient. However, it is known that it can effectively block both UVA and UVB. It is not showing the desired performance.

The present invention was developed in consideration of the above-described prior art, and blocks ultraviolet rays by mixing an organic and inorganic sunscreen into a cosmetic composition with excellent whitening effect, including bifidus extract, star anise extract, Virginia fern leaf extract, and Indian gooseberry fruit extract. The purpose is to provide a cosmetic composition for sunscreen that can exhibit a skin whitening effect.

In addition, the purpose is to provide a cosmetic composition for sunscreen that can exhibit a skin improvement effect by containing hot spring water containing minerals.

In addition, the purpose is to provide a cosmetic composition for sunscreen that is homogeneously mixed so that solid formulations such as sun sticks or sun balms can be manufactured.

The cosmetic composition for sunscreen of the present invention to solve the above problems includes 20 to 30 parts by weight of star anise extract, 10 to 20 parts by weight of Virginia fern leaf extract, and 5 to 10 parts by weight of Indian gooseberry fruit extract, based on 100 parts by weight of bifidus extract. parts by weight, 5 to 10 parts by weight of an inorganic sunscreen, 1 to 5 parts by weight of an organic sunscreen, and 1 to 5 parts by weight of a sunscreen booster.

At this time, the organic sunscreen is ethylhexyl salicylate, ethylhexylmethoxycinnamate, ethylhexyltriazone, butylmethoxydibenzoylmethane, isoamyl p-methoxycinnamate, octocrylene, and bis-ethylhexyloxy. It is one or more of phenol methoxyphenol triazine, the inorganic sunscreen is one or more of silicon dioxide, zinc oxide, or titanium dioxide, and the sunscreen booster agent may be surface-treated silicon dioxide particles. .

In addition, the cosmetic composition for sunscreen may additionally include a mixed extract of mulberry bark and celestial root.

In addition, the mixed extract of the mulberry bark and the root of the talismanum may be included in the range of 1 to 20 parts by weight based on 100 parts by weight of the bifidus extract.

Additionally, the cosmetic composition for sunscreen can be used in a solid cosmetic formulation.

The cosmetic composition for sunscreen according to the present invention contains natural ingredients that can improve the whitening effect and organic and inorganic sunscreens, so it can exhibit a sunscreen effect and a skin whitening effect, making it suitable for application to a sunblock cream. .

In addition, it can show an effect of improving safety by showing a UV blocking effect against UVA and UVB rays while reducing the amount of organic sunscreen used.

Additionally, it can have a skin improvement effect by including hot spring water containing minerals.

In addition, each ingredient can be mixed homogeneously, making it easy to produce solid formulations such as sun sticks or sun balms as well as cream formulations.

Hereinafter, the present invention will be described in detail.

The cosmetic composition for sunscreen according to the present invention contains 20 to 30 parts by weight of star anise extract, 10 to 20 parts by weight of Virginia fern leaf extract, 5 to 10 parts by weight of Indian gooseberry fruit extract, and 5 to 5 parts by weight of inorganic sunscreen based on 100 parts by weight of bifidus extract. to 10 parts by weight, 1 to 5 parts by weight of an organic sunscreen, and 1 to 5 parts by weight of a sunscreen booster.

The bifidus extract, star anis extract, Virginia fern leaf extract, and Indian gooseberry fruit extract are known as cosmetic compositions disclosed in Korean Patent No. 10-2087904. By containing these components, the production of tyrosinase and melamine is suppressed. It has a whitening effect.

The Bifidobacterium produces metabolites useful to the human body and is a strain with high safety enough to be used as a food raw material. In the present invention, a Bifidobacterium extract obtained using the Bifidobacterium is used. The Bifidobacterium extract is obtained by culturing the Bifidobacterium and crushing the cells with a homogenizer. It is a fermented lysate of Bifida containing metabolic components, cytoplasm, cell wall components, polysaccharides, etc. of the Bifidobacterium, and is used to reduce wrinkles and skin tone. It is an ingredient that has the effect of improving skin health and supplying moisture and nutrition.

In addition, the star anise extract shows the effect of improving skin whitening and wrinkles when used in combination with bifidus extract and Virginia fern leaf extract. The star anise extract is a fermented extract obtained by fermenting star anise fruit with bifidobacteria. Even if the star anise extract is used as is without fermentation, it has a skin whitening effect, but skin problems and psoriasis may occur, so it is preferable to use it in the form of a fermented extract.

The star anise extract is preferably contained in the range of 10 to 20 parts by weight based on 100 parts by weight of the bifidus extract. If the content of the star anise extract is too small, the whitening and wrinkle improvement effect will not be sufficient even when used in combination with the bifidus extract and the Virginia marigold leaf extract, and if the content is too high, the adhesion may not be sufficient for use as a cosmetic composition.

In addition, the Virginia wildflower leaf extract is an ingredient that improves wrinkles when used in combination with star anise extract and improves adhesion and durability without clumping even over a long period of time when used in a cream formulation for sunscreen. When the Virginia leaf extract is fermented with bifidobacteria, its durability and adhesion are reduced, so it is preferable to use it without fermentation.

The Virginia fern leaf extract is used in the range of 10 to 20 parts by weight based on 100 parts by weight of the Bifidus extract. If the content of the Virginia fern leaf extract is too small, the wrinkle improvement effect may not be sufficient and durability and adhesion may be reduced, and if it is too much, skin itching may occur.

In addition, the Indian gooseberry fruit extract is used with bifidus extract to provide moisture to the skin and improve whitening effect. If the Indian gooseberry fruit extract is fermented with Bifidobacterium, the whitening effect may be reduced, so it is preferable to use it without fermentation.

The Indian gooseberry fruit extract is preferably used in the range of 5 to 10 parts by weight based on 100 parts by weight of the bifidus extract. If the content of the Indian gooseberry fruit extract is too small, the amount of moisture supplied to the skin may be insufficient and the whitening effect may be reduced even when used together with the bifidus extract, and if it is too much, skin problems may occur.

In addition, the cosmetic composition for sunscreen may additionally include a mixed extract of mulberry bark and celestial root.

The mixed extract of the mulberry bark and the apricot root is used with the bifidus extract and the Virginia fern leaf extract to retain moisture on the skin for a long time. When used as a cream formulation, it is an ingredient that improves adhesion and does not clump up over time. am. It is a fermented extract obtained by fermenting a mixture of the above-mentioned mulberry bark and Skytari root with bifidobacteria. If the mixture of mulberry bark and skytari root is used as is without fermenting it with bifidobacteria, erythema may occur. Moreover, if mulberry bark and skytari root are fermented separately without mixing and then mixed and used later, the moisture retention time and adhesion may be reduced compared to the case where the two substances are mixed and fermented.

In addition, the mixture of mulberry bark and sky tari root may be a mixture of mulberry bark and sky tree root at a weight ratio of 1:0.2-0.8, preferably at a weight ratio of 1:0.3-0.5. If the content of Skytari root based on the above-mentioned mulberry bark is too small, sustainability and adhesion may be reduced, and if it is too much, it may cause skin dryness.

In addition, it is preferable that the mixed extract of the mulberry bark and Skytari root is included in the range of 1 to 20 parts by weight based on 100 parts by weight of the bifidus extract. If the content of the mixed extract is too small, it may be difficult to exert a long-term effect even when used together with the bifidus extract and Virginia fern leaf extract, and durability and adhesion may be reduced. If it is too much, adhesion may be reduced and skin itching may occur. .

Additionally, the extract is preferably a hot spring water extract using hot spring water. Since hot spring water contains various minerals, it is known to have a skin-improving effect when applied to cosmetics. In the present invention, the extract is manufactured using Dogo hot spring water. The extract can be manufactured using distilled water, but the skin beauty efficacy can be improved by using hot spring water.

The Dogo Hot Spring water is a cold mineral spring whose water temperature is maintained at 35℃. The water quality is a simple sulfur spring, one of the four major sulfur hot springs in the East. The hydrogen ion concentration reaches 8.7%, and other solid residues, silicic acid, sodium, calcium, magnesium, etc. It is composed of ingredients. It is known to be effective in neuralgia, skin diseases, gastrointestinal diseases, arthritis, arteriosclerosis, chronic bronchitis, constipation, aftereffects of trauma, rheumatism, gynecological diseases, diabetes, genital diseases, digestive diseases, and skin beauty.

Specifically, the ingredients of the cosmetic composition, such as star anise extract, Virginia wildflower leaf extract, Indian gooseberry extract, and the additionally contained mixed extract of mulberry bark and skytari root, were all prepared using Dogo hot spring water.

The water-soluble vitamins may be any that can be mixed into cosmetics, but are preferably vitamin B1, vitamin B2, vitamin B6, pyridoxine, pyridoxine hydrochloride, vitamin B12, pantothenic acid, nicotinic acid, nicotinic acid amide, folic acid, vitamin C, and vitamin H. and the like, and their salts (thiamine hydrochloride, sodium ascorbate, etc.) or derivatives (sodium ascorbic acid-2-phosphate, magnesium ascorbic acid-2-phosphate, etc.) can also be used in the present invention. Included in water-soluble vitamins. The water-soluble vitamins can be obtained by conventional methods such as microbial transformation, purification of microbial cultures, enzyme methods, or chemical synthesis.

The fat-soluble vitamins can be any one as long as they can be mixed in cosmetics, but preferably include vitamin A, carotene, vitamin D2, vitamin D3, vitamin E, etc., and their derivatives (ascorbin palmitate, ascorbic acid stearate) Bean, ascorbic acid dipalmitate, dl-alpha tocopherol acetate, dl-alpha tocopherol nicotinic acid (vitamin E, DL-pantothenyl alcohol, D-pantothenyl alcohol, pantothenyl ethyl ether, etc.) are also included in the fat-soluble vitamins used in the present invention. do.

The polymer peptide may be any one as long as it can be mixed into cosmetics, but preferably includes collagen, hydrolyzed collagen, gelatin, elastin, hydrolyzed elastin, and keratin. The polymer peptide can be purified and obtained by conventional methods such as purification of microbial culture broth, enzyme method, or chemical synthesis, or can be usually purified and used from natural products such as dermis of pigs, cows, etc., and silk fiber of silkworms.

The polymer polysaccharide can be anything as long as it can be mixed in cosmetics, but preferably includes hydroxyethyl cellulose, xanthan gum, chondroitin sulfate or its salts (sodium salt, etc.). For example, chondroitin sulfate or its salt can usually be purified and used from mammals or fish.

The sphingolipid may be anything that can be mixed into cosmetics, but preferably includes ceramide, phytosphingosine, and sphingosaccharide lipid. The sphingolipids can usually be purified by conventional methods from mammals, fish, shellfish, yeast, or plants, or obtained by chemical synthesis.

The seaweed extract can be anything as long as it can be mixed in cosmetics, but preferably includes brown algae extract, red algae extract, green algae extract, etc., and also calrageenan, arginic acid, and arginic acid purified from these seaweed extracts. Sodium, potassium alginate, etc. are also included in the seaweed extract used in the present invention. Seaweed extract can be obtained by purifying it from seaweed by conventional methods.

The cosmetic composition of the present invention is suitable for forming a solid cosmetic formulation for UV protection, and can be used as a raw material for sunscreen products such as sun sticks or sun balms. The cosmetic composition contains an inorganic sunscreen and an organic sunscreen like a typical sunscreen, but the amount of organic sunscreen used is reduced. Therefore, in order to reduce the amount of organic sunscreen used and still achieve a sunscreen effect, it contains a sunscreen booster.

That is, the cosmetic composition may include 5 to 10 parts by weight of an inorganic sunscreen, 1 to 5 parts by weight of an organic sunscreen, and 1 to 5 parts by weight of a sunscreen booster.

As the inorganic sunscreen, ingredients known to have a UVA blocking effect are used. Specifically, one or more of silicon dioxide, zinc oxide, or titanium dioxide may be used. In addition, the organic sunscreen uses ingredients known to have a UVB blocking effect, specifically, ethylhexyl salicylate, ethylhexyl methoxycinnamate, ethylhexyl triazone, butyl methoxydibenzoylmethane, and isoamyl p- Any one or more of methoxycinnamate, octocrylene, and bis-ethylhexyloxyphenol methoxyphenol triazine can be used.

In particular, it was found that titanium dioxide was preferably used as the inorganic sunscreen, and that ethylhexyl salicylate and ethylhexyl methoxycinnamate were used as the organic sunscreen. Salicylic acid compounds not only have relatively high safety compared to other organic sunscreens and have excellent UVB blocking effects, but also have the best compatibility with the sunscreen booster component described later, making them suitable for use in the sunscreen cosmetic composition of the present invention. It was found to be suitable for .

In addition, a sunscreen booster agent is added to enhance the sunscreen effect. The sunscreen booster agent does not have a sunblock effect on its own, but when used together with a sunscreen, it promotes the dispersion of the sunscreen agent and improves the sunscreen effect. It is known as an ingredient that Such UV-blocking boosters include butyloctyl salicylate, ethylene polyacrylate-15, and styrene-acrylate copolymer.

In the present invention, the UV protection booster uses surface-treated silicon dioxide particles. This is added to obtain a UV blocking effect while reducing the content of the organic sunscreen. In particular, it is used to improve the UV blocking performance of the sunscreen without affecting the natural ingredients.

In particular, the application of silicon dioxide particles surface-treated with acrylic groups acts as a booster for sunscreen.

To produce the silicon dioxide particles, silica sol (colloidal silica) is used. The silica sol is monodisperse silicon dioxide particles of 10 to 20 nm and can form acrylic groups on the surface through the reaction between surface hydroxyl groups and acrylic acid. Since the silicon dioxide particles are nanoparticles, they have excellent compatibility with inorganic sunscreens in the form of oxide particles, and since the surface acrylic groups can be dispersed through hydrogen bonds with the hydroxyl groups of organic sunscreens, they can act as a booster for sunscreens. appear.

The surface-treated silicon dioxide particles can be easily manufactured by mixing acrylic acid and silica sol and reacting in a catalytic atmosphere. The silica sol prepared in this way can be used by removing unreacted acrylic acid by filtration and washing, and mixing the obtained powder with the organic and inorganic sunscreen. At this time, it is preferable to mix 10 to 15 parts by weight of acrylic acid with respect to 100 parts by weight of silica sol. In addition, since it is difficult to remove even if there is too much unreacted acrylic acid, it is preferable to mix within the above range.

The main ingredients of the cosmetic composition for sunscreen are formed by mixing the natural ingredients consisting of the bifidus extract, star anise extract, Virginia fern leaf extract, and Indian gooseberry fruit extract with a sunscreen consisting of an inorganic sunscreen, an organic sunscreen, and a sunscreen booster. In order to manufacture a sunscreen cream, a sunscreen cream can be manufactured by mixing ingredients such as solvents, skin conditioning agents, stabilizers, thickeners, pigments, and preservatives. Additionally, sun sticks or sun balms, which are solid cosmetic formulations, can be manufactured by adding wax and oil ingredients.

In order to confirm the ultraviolet ray blocking and skin whitening effects of the cosmetic composition of the present invention, a cosmetic composition was prepared as shown in Table 1 (units in Table 1 are parts by weight). Among the ingredients used in Table 1, the bifidus extract was purchased and used from Aju Cosmetics Co., Ltd., and the star anise extract was added to 100 ml of star anise ^by adding 1 /㎖) 1㎖ was inoculated and fermented at 37°C for 2 days, then 1 kg of Dogo Hot Spring water was added to the fermented product, and then ultrasonic extraction was performed for 30 minutes using an ultrasonic extractor. In addition, the Virginia wildflower leaf extract and Indian gooseberry fruit extract were obtained by adding 1 kg of Dogo Hot Springs water to each of the Virginia wildflower leaf and Indian gooseberry fruit and then ultrasonic extraction for 30 minutes using an ultrasonic extractor. In addition, the mixed extract of mulberry bark and Sky tree root (hereinafter referred to as 'mixed extract') is a 10% solution of Bifidus strain (Difco BL agat, Ref 210095) in 100 ml of a mixture of mulberry bark and Sky tree root at a weight ratio of 1:0.5. Prepared by inoculating 1 ㎖ of activated Bifidobacterium ( ¹ did.

The UV protection booster was prepared by mixing 12 parts by weight of acrylic acid with 100 parts by weight of silica sol in a sulfuric acid catalyst atmosphere for 30 minutes, centrifuging at 1,500 rpm, and filtering and washing the obtained precipitate.

The solvent used was a mixed solvent of hot spring water and ethanol at a weight ratio of 99.9:1, and the skin conditioning agent was butylene glycol, cyclopentasiloxane, dicaprylyl carbonate, biosaccharide gum-1, dimethicone, 1, A mixture of 2-hexanediol, Portulaca oleracea extract, tocopheryl acetate, glycerin, pentaerythrityl distearate, isohexadecane, and allantoin was used, and as stabilizers, cetaaryl alcohol, glyceryl stearate, polysorbate 60, and PEG were used. A mixture of -100 stearate and polysorbate 80 was used, and the thickeners used were sodium acrylate/sodium acryloyldimethyltaurate copolymer, ammonium acryloyldimethyltaurate/V picopolymer, and didimethicone/vinyl diem. A mixture of methicone crosspolymer and xanthan gum was used. A mixture of CI 77492, CI 77491, and CI 77499 was used as a pigment, phenoxyethanol was used as a preservative, and EDTA·2Na was used as a metal ion sequestering agent.

To measure the ultraviolet protection factor (SPF) of the cosmetic compositions of Examples and Comparative Examples, a 2 mg/cm2 sample was applied to the transport tape, dried for 15 minutes, and then ultraviolet rays were measured using an ultraviolet ray measuring device (SPA 290S).

In addition, in order to measure the UVA protection level (PFA), the above sunbalm-type formulation was applied in an amount of 2 mg/cm2 to the back area of 10 male test subjects and 10 female test subjects aged 18 to 50 years and 300 W. After irradiating with ultraviolet A for 2 hours, the minimum sustained instantaneous pulverization (MPPD) was determined, and PFA was calculated as the ratio of the MPPD of the area where the sample was applied to the MPPD of the area where the sample was not applied. In addition, PA was evaluated according to the classification criteria of 2~4: PA+, 4~8: PA++, 8~16: PA+++, and >16: PA++++ according to the PFA value. The results are shown in Table 2.

SPF PFA PA Example 1 29.52±0.50 16.89±0.32 +++ Example 2 29.44±0.55 16.93±0.56 +++ Comparative Example 1 22.50±0.62 12.75±0.35 +++ Comparative example 2 20.58±0.71 11.68±0.36 +++

Looking at the results in Table 2, Comparative Examples 1 and 2, which did not contain a sunscreen booster, showed lower SPF and PFA values, showing poor sunscreen performance. In particular, in Comparative Example 2, although the content of organic sunscreen was increased, the SPF and PFA values were low, suggesting that the sunscreen was unevenly contained.

In addition, the dopachrome method was used to evaluate the effect of inhibiting tyrosiase enzyme activity. The sample solution was mixed with 150㎕ of mushroom tyrosinase-150unit, 225㎕ of 2.5mM L-tyrosine, and 225㎕ of 0.4M hepes buffer (pH 6.8), and the absorbance was measured at 475㎚ before and after incubation for 15 minutes. The tyrosinase inhibitory ability was calculated using the following equation, and the results are shown in Table 3.

Looking at the results in Tables 3 and 4, the cosmetic composition of the example showed improved tyrosinase and melanin inhibition effects compared to the cosmetic composition of the untreated group and the comparative example. This result suggests that the same level of whitening effect is achieved even when natural ingredients are mixed with sunscreen to produce a cosmetic composition for sunscreen.

In addition, in order to confirm the makeup effect of the cosmetic composition of the present invention, adhesion and irritation when entering the eyes were evaluated on 12 male test subjects and 12 female test subjects aged 18 to 50 years. Adhesion was ranked by evaluating the relative stickiness and degree of absorption when 5g of the sunbalm-type formulation was applied to the arm, and the ranking was determined from the average value. The degree of irritation when entering the eyes was determined by glaring at a sample of 3mg/cm2. After 10 minutes of application, the presence or absence of irritation was examined and evaluated based on the number of test subjects who responded that there was no or little irritation. The results are shown in Table 5.

Adhesion eye irritation Example 1 2 17 Example 2 One 15 Comparative Example 1 4 11 Comparative example 2 5 12

Looking at the results in Table 5, the cosmetic compositions of Examples 1 and 2 were evaluated to have relatively better adhesion compared to Comparative Examples 1 and 2, which means that the content of sunscreen is relatively reduced and thus the amount of solvent or natural ingredients is reduced. This appears to be due to an increase in content. In addition, the irritation evaluation results showed that in Examples 1 and 2, the number of test subjects who responded that there was no or little eye irritation was greater than in Comparative Examples 1 and 2, indicating the effect of reducing irritation to the skin or eyes. It was found that

From these results, it was found that the cosmetic composition of the present invention has excellent UV blocking and whitening effects, and has good dispersibility and hardness of the sunscreen, making it suitable for application to sunsticks or sunbalms, which are solid cosmetic formulations for UV protection.

Although the present invention has been described through preferred embodiments as described above, it is not limited to the above embodiments and various modifications and modifications may be made by those skilled in the art without departing from the spirit of the invention. Change is possible. Such modifications and variations should be considered to fall within the scope of the present invention and the appended claims.
