Description

Cosmetic composition for improving skin condition containing beet root extract

[0001] The present invention relates to a cosmetic composition comprising a sugar beet root extract, and more particularly, to a cosmetic composition comprising a sugar beet root extract for enhancing skin moisturizing, enhancing skin elasticity, and improving skin itching.

[0002] Histologically, the skin is composed of the epidermis, dermis, and subcutis. The epidermis can be easily damaged by lifestyle factors such as excessive washing and bathing, environmental factors like dry air and pollutants, and endogenous diseases such as atopic dermatitis and aging skin. Therefore, extensive research is being conducted to maintain adequate skin hydration by supplying moisture from outside sources or preventing moisture loss from the body. Various moisturizers have been developed and are widely used in cosmetics. However, chemical ingredients can cause adverse effects such as skin allergies and skin problems, so eco-friendly ingredients such as plant-based ingredients are gaining popularity.

[0003] Meanwhile, pruritus refers to a skin condition that makes one want to scratch, and can be triggered by external stimuli such as external contact, temperature changes, stress, or chemical, physical, or electrical stimulation. Furthermore, those with skin conditions such as atopy, psoriasis, or contact dermatitis, as well as those with sensitive skin, often experience itching as a symptom. Sensitive skin individuals are those with the potential for skin disorders without any clinical or histological signs of skin lesions. These individuals complain of itching not only visually but also sensorially after using cosmetics, soaps, or shampoos.

[0004] Sugar beet (Beta vulgaris subsp. vulgaris Altissima Group) is a biennial herb of the Amaranth family, with a straight stem and a height of about 1 m. The leaves are slightly thick, oblong, and wavy at the edges. The roots of sugar beet are large, thick, spindle-shaped, yellowish-white or pink, and contain a lot of sugar. In summer, small, yellow-green flowers bloom in spikes. The perianth is deeply divided into five lobes. The large, succulent roots produce sugar and are also used as livestock feed. Unlike sugarcane, which is widely cultivated in tropical and subtropical regions, sugar beets are widely cultivated in cool and temperate zones.

[0005] As previously discussed, with the recent emergence of adverse effects caused by chemical ingredients in cosmetics, consumer interest in cosmetics made with natural ingredients is growing. Consequently, many cosmetics using natural ingredients are being developed to reduce skin irritation caused by various chemicals. Natural ingredients have the advantage of relatively fewer skin side effects. However, research and development on the use of beet root extract as a standalone cosmetic ingredient remains largely lacking.

[0006] The present inventors have endeavored to develop a cosmetic composition for improving skin condition containing a plant extract as an active ingredient, and as a result, have confirmed that a composition containing a sugar beet root extract has the effect of significantly increasing skin moisturizing and improving skin itchiness, thereby completing the present invention.

[0007] One object of the present invention is to provide a cosmetic composition for improving skin moisturizing and skin itching, which contains a sugar beet root extract.

[0008] A cosmetic composition for improving skin condition according to the present invention comprises a sugar beet root extract and has at least one of the effects of improving skin moisturizing, improving skin elasticity, and improving skin itching.

[0009] In one embodiment, the beet root extract may be included in an amount of 50% to 90% by weight based on the entire cosmetic composition.

[0020] Additionally, as used in this specification and claims, the singular forms “a” or “an” should generally be construed to mean “one or more” unless otherwise indicated or clear from the context to be in the singular form.

[0021] The term "about" used in this specification to express volume, time (duration), concentration, content, temperature, etc. means that there is a tolerance of up to 10% in the corresponding value or range of values.

[0022] Beet (Beta vulgari) is a species of flowering plant belonging to the subfamily Betoideae of the Amaranthaceae family. There are five cultivar groups within the subspecies of Beta vulgari. Among them, sugar beet belongs to the Altissima group, one of the five cultivar groups. That is, the species of sugar beet is Beta vulgaris, the subspecies is Beta vulgaris subsp. vulgaris, and the cultivar group belongs to Altissima.

[0023] The above-mentioned beet root has been widely used as a food ingredient for over 25 years, serving as a source of sugar and dietary fiber. As a natural ingredient, beet root has had virtually no reported adverse effects or toxicity, making it safe for use in cosmetic compositions.

[0024] The cosmetic composition for improving skin condition according to the present invention comprises a beet root extract and has at least one of the following effects: improving skin hydration, improving skin elasticity, and alleviating skin itching. Applying beet root extract to the skin increases skin moisture content, leading to an improvement in skin elasticity. Individuals with sensitive skin types who experience symptoms such as itching may experience an improvement in their perceived itching.

[0025] In one embodiment, the beet root extract may be included in an amount of 50 wt% to 90 wt% based on the entire cosmetic composition. Preferably, the beet root extract may be included in an amount of 55 wt% to 90 wt%. More preferably, the beet root extract may be included in an amount of 60 wt% to 86 wt%. If the beet root extract is included in an amount less than the above range, the skin condition improvement effect may not be exhibited. If the beet root extract is used in an amount exceeding the above range, the formulation stability is low for commercialization as a cosmetic.

[0026] At this time, dexpanthenol may be included in an amount of 0.1 wt% to 10 wt%. Preferably, it may be included in an amount of 0.1 wt% to 5 wt%. More preferably, it may be included in an amount of 0.3 wt% to 3 wt%.

[0027] At this time, allantoin may be included in an amount of 0.1 wt% to 10 wt%. Preferably, it may be included in an amount of 0.1 wt% to 5 wt%. More preferably, it may be included in an amount of 0.25 wt% to 0.3 wt%.

[0028] At this time, glycerin may be included in an amount of 0.1 wt% to 10 wt%. Preferably, it may be included in an amount of 0.3 wt% to 7.0 wt%. More preferably, it may be included in an amount of 0.5 wt% to 5.0 wt%.

[0029] At this time, glyceryl glucoside may be included in an amount of 0.1 wt% to 1.0 wt%. Preferably, it may be included in an amount of 0.1 wt% to 0.5 wt%. More preferably, it may be included in an amount of 0.1 wt% to 0.2 wt%.

[0030] In one embodiment, the sugar beet root extract may contain glucosyl ceramide as an active ingredient.

[0031] Among the layers of the skin, the epidermis serves as a functional barrier against the external environment. Disruption of this barrier function can lead to moisture loss and increased penetration of various stimuli, which can lead to skin diseases such as dry skin, atopic dermatitis, and psoriasis. Lamellae, which form between cells in the outermost layer of the skin, serve as a sweat barrier in humans. The stratum corneum of the human epidermis consists of 50% lipid lamellae composed of ceramide (N-acylsphingosine), a sphingolipid that forms the skin. Ceramide content gradually decreases with aging. Sphingolipids are essential components of the mammalian permeability barrier. Therefore, ceramides play a crucial role in maintaining youthful, healthy skin. Ceramides are known to have moisturizing and smoothing effects. Because ceramides are a crucial natural component of the epidermal protective barrier, a decrease in epidermal ceramides can lead to various skin conditions, including dry skin, atopic dermatitis, and psoriasis. Therefore, the present invention seeks to attenuate skin barrier damage by compensating for the deficiency of glucosyl ceramides contained in beet root extract.

[0032] Sugar beet roots contain fiber containing relatively large amounts of glucosyl ceramide. Ceramide, a plant-based lipid component, can be extracted in large quantities using an extraction solvent containing ethanol.

[0033] Glucosyl ceramide, an effective ingredient in sugar beet root, has a structure as shown in chemical formula 1 below.

[0034] [Chemical Formula 1]

[0035]

[0036] The basic structure of ceramides consists of long-chain sphingoid bases with amide-linked fatty acid chains of 14 to 26 carbon atoms in length. Ceramides derived from rice bran, wheat germ, and konjac are mainly d18:2. 4t,8c and d18:1 8c 8-cis-unsaturated bonds, whereas beet root-derived ceramides are composed of d18:2 4t,8t , d18:1 8t It consists of 8-trans-unsaturated bonds. The fatty acid chains of ceramides derived from sugar beet root are mostly palmitic acid, whereas those from other crops typically have chains of 16 to 24 carbon atoms. Since the main fatty acids found in mammalian epidermal ceramides are palmitic acid and linoleic acid, glucosyl ceramides derived from sugar beet root extract have an advantage over ceramides from other crops.

[0037] In one embodiment, the sugar beet root extract can be extracted using an aqueous ethanol solution as an extraction solvent. Preferably, an aqueous ethanol solution of 65 v / v% to 75 v / v%, more preferably 70 v / v%, can be used as the extraction solvent.

[0038] Ceramide contained in sugar beet roots is a plant lipid component and can be obtained in large quantities when extracted using an extraction solvent containing ethanol.

[0039] In one embodiment, the sugar beet root extract can be extracted at 15°C to 35°C. Preferably, the extract can be extracted at room temperature.

[0040] Additionally, the sugar beet root extract can be extracted by any one method selected from immersion extraction, heating extraction, ultrasonic extraction, reflux cooling extraction, hot water extraction, and cold immersion extraction.

[0041] In one embodiment, the sugar beet root extract may be extracted for 24 to 72 hours. Preferably, it may be extracted for 36 to 60 hours. More preferably, it may be extracted for 46 to 50 hours.

[0042] Beet root extract can be used in liquid form after the extraction process, filtered. This can be done using filter paper, charcoal, or diatomaceous earth.

[0043] Additionally, sugar beet root extract can be used in powder form by further including a drying process after the filtration process. The drying process can be performed using spray drying or freeze drying methods.

[0044] In one embodiment, the beet root extract may be in any one formulation selected from the group consisting of a toner, a lotion, a cream, an essence, and an ointment.

[0045] The above-mentioned toner may include mist, toner, and skin, and the above-mentioned cream may include, but is not limited to, a nourishing cream, an eye cream, and the like.

[0046] In the case of a toner containing a beet root extract, the content of the beet root extract may be 50% to 95% by weight based on the entire cosmetic composition. Preferably, it may be 70% to 95% by weight. More preferably, it may be 80% to 90% by weight.

[0047] For lotions containing beet root extract, the content of beet root extract may range from 50% to 95% by weight based on the composition. Preferably, it may range from 60% to 85% by weight. More preferably, it may range from 70% to 80% by weight.

[0048] For creams containing beet root extract, the content of beet root extract may range from 50% to 95% by weight based on the composition. Preferably, it may range from 55% to 80% by weight. More preferably, it may range from 60% to 70% by weight.

[0049] In addition, the cosmetic composition may further include additives that can be used in conventional cosmetics, such as moisturizers, viscosity modifiers, pH adjusters, gelling agents, softeners, suspending agents, stabilizers, fragrances, emulsifiers, preservatives, oils, water, dyes, pigments, etc., but is not limited thereto.

[0050] Hereinafter, the present invention will be described in more detail through examples. These examples are intended to explain the present invention more specifically, but the scope of the present invention is not limited by these examples.

[0051] [Example 1] Sugar beet root extract

[0052] Sugar beet roots were cut into an appropriate size and ground into fine particles. 10 times the volume of 70 v / v% ethanol aqueous solution was added to 100 g of the sugar beet root powder, and the mixture was soaked and extracted at 25°C for 48 hours. The extract was then filtered through a Whatman filter paper to obtain a liquid extract.

[0053] [Manufacturing Example 1] Mist

[0054] The sugar beet root extract of Example 1, dexpanthenol, allantoin, glycerin, and glyceryl glucoside were mixed in the contents shown in Table 1 below, and formulated to be usable as a mist.

[0055] [Manufacturing Example 2] Lotion

[0056] The sugar beet root extract of Example 1, dexpanthenol, allantoin, glycerin, and glyceryl glucoside were mixed in the contents shown in Table 1 below, and formulated to be usable as a lotion.

[0057] [Example 3] Cream

[0058] The beet root extract of Example 1, dexpanthenol, allantoin, glycerin, and glyceryl glucoside were mixed in the contents shown in Table 1 below, and formulated to be usable as a cream.

[0059] Manufacturing Example 1 Manufacturing Example 2 Manufacturing Example 3 Ingredient Name Content (%) Content (%) Content (%) Sugar Beet Root Extract 88.0 76.5 63.4 Dexpanthenol 3.0 0.3 0.3 Allantoin 0.25 0.3 0.3 Glycerin 0.5 3.0 5.0 Glyceryl Glucoside 0.13 0.13 0.13

[0060] [Comparative Manufacturing Example 1]

[0061] Dexpanthenol, allantoin, glycerin, and glyceryl glucoside were mixed in the amounts shown in Table 2 below and formulated for use as a cream.

[0062] [Comparative Manufacturing Example 2]

[0063] The beet root extract of Example 1, dexpanthenol, allantoin, glycerin, and glyceryl glucoside were mixed in the contents shown in Table 2 below, and formulated to be usable as a cream.

[0064] Comparative Manufacturing Example 1 Comparative Manufacturing Example 2 Ingredient Name Content (%) Content (%) Sugar Beet Root Extract 0.046.0 Dexpanthenol 0.30.3 Allantoin 0.30.3 Glycerin 5.05.0 Glyceryl Glucoside 0.130.13

[0065] [Experimental Example 1] Skin Moisture Content Test

[0066] A skin moisture content test was conducted on 50 male and female adult volunteers aged 20 to 55 years with dry skin types. The participants were randomly divided into five groups of 10 each, and equal amounts (by mass) of Preparation Examples 1 to 3 and Comparative Preparation Examples 1 to 2 were applied to the entire face. The skin moisture content on the right cheek was measured using a Corneometer (Courage+Khazaka Electronic) that uses the principle that electric capacity changes according to skin moisture content. Each value was measured four times, and the highest and lowest values ​​were removed and then averaged.

[0067] The results are shown in Table 3 below. In the table, the initial value is before applying the manufacturing example, and the 4-week result is after applying the manufacturing example twice a day, in the morning and evening, for 4 weeks.

[0068] Initial 4 weeks Manufacturing Example 145.155.2 Manufacturing Example 245.453.1 Manufacturing Example 344.949.7 Comparative Manufacturing Example 145.045.6 Comparative Manufacturing Example 245.245.9

[0069] Referring to Table 3, it can be confirmed that when Manufacturing Examples 1 to 3 were applied, the skin moisture content significantly increased compared to when Comparative Manufacturing Examples 1 to 2 were applied. When Comparative Manufacturing Example 1 was applied, there was no change in the skin moisture content, and in the case of Comparative Manufacturing Example 2, although there was a slight increase, the effect was minimal compared to the Manufacturing Examples. Since Manufacturing Example 1 contained the highest content of beet root extract, and Manufacturing Example 3 contained the lowest content of beet root extract, it can be seen that the skin moisture content increased in a dose-dependent manner. However, Manufacturing Example 1 is a mist formulation, Manufacturing Example 2 is a lotion formulation, and Manufacturing Example 3 is a cream formulation, so the degree of efficacy may vary depending on the typical skin application amount.

[0070] From the above results, it can be confirmed that a cosmetic composition containing beet root extract maintains a high skin moisture content and exhibits an excellent skin moisturizing effect.

[0071] [Experimental Example 2] Transepidermal Water Loss Test

[0072] A skin moisture content test was conducted on 50 male and female adult volunteers aged 20 to 55 years with dry skin type. The participants were randomly divided into five groups of 10 each, and the same amount (by mass) of Preparation Examples 1 to 3 and Comparative Preparation Examples 1 to 2 was applied to the entire face. The water vapor pressure was measured at two points 1 to 2 mm away from the skin surface on the right cheek, and the amount of moisture transpired from the epidermis was calculated and expressed as the amount of water lost per hour per square meter of skin (g / h m2) using a Tewameter (Courage+Khazaka Electronic). Each value was measured four times, and the highest and lowest values ​​were removed and then the average was calculated.

[0073] The results are shown in Table 4 below. In the table, the initial results are before applying the manufacturing example, and the 2-week and 4-week results are after applying the manufacturing example twice a day, in the morning and evening, for 2 and 4 weeks, respectively.

[0074] 0 weeks 2 weeks elapsed 4 weeks elapsed Manufacturing example 176.6621.6615.35 Manufacturing example 275.4923.6418.62 Manufacturing example 375.1624.9920.16 Comparative manufacturing example 176.2374.6371.21 Comparative manufacturing example 275.8673.5670.62

[0075] Referring to Table 4, a significant difference in transepidermal water loss (TEWL) was observed between the comparative and comparative preparation examples. A comparison of the improvement rates between the preparation examples and the comparative preparation examples revealed a statistically significant skin barrier strengthening effect after two weeks of use. The transepidermal water loss tended to decrease significantly as the dosage of the preparation examples increased. From the above results, it can be confirmed that a cosmetic composition containing beet root extract exhibits an excellent skin moisturizing effect by reducing transepidermal water loss.

[0076] Meanwhile, it is known that skin barrier dysfunction causes various skin diseases, which are reflected in increased transepidermal water loss (TEWL). Alterations in genetic and / or environmental factors within the skin barrier, such as the lipid layer, natural moisturizing factors, and the stratum corneum, can cause skin barrier damage. When skin barrier function is impaired, various environmental allergens and microorganisms can enter, triggering an inflammatory response and leading to itching.

[0077] [Experimental Example 3] Skin Elasticity Test

[0078] A skin elasticity test was conducted on 50 male and female adult volunteers aged 20 to 55 years with dry skin type. The participants were randomly divided into five groups of 10 each, and equal amounts (by mass) of Preparation Examples 1 to 3 and Comparative Preparation Examples 1 to 2 were applied to the entire face, a probe was placed on the skin surface on the right cheek, and negative pressure was used to pull the skin area into the probe. Skin elasticity was evaluated using a Cutometer (Courage+Khazaka Electronic Co., Ltd.), which measures the length of skin pulled to the probe using a glass prism. The results are shown in Table 5 below. In the table, the initial results are before applying the Preparation Examples, and the 4-week results are after applying the Preparation Examples twice a day, in the morning and evening, for 4 weeks.

[0079] In addition, the R2 index in Table 5 is the skin length recovery ratio (Ua1 / Uf1) after stretching and contracting, and the closer this ratio is to 1.00, the better the elasticity. The R2 value of an ideal elastic material is 1.00, and the value of normal skin is 0.3 to 0.5. The R7 index indicates the skin elasticity ratio during contraction (Ur1 / Uf1), and the most elastic skin has an R7 value close to 1.00. Skin elasticity was measured four times to reduce errors, and the highest and lowest values ​​were removed and then the average was taken.

[0080] Initial 4 weeks R2 Manufacturing Example 10.350.67 Manufacturing Example 20.370.66 Manufacturing Example 30.340.54 Comparative Manufacturing Example 10.350.36 Comparative Manufacturing Example 20.360.39 R7 Manufacturing Example 10.210.51 Manufacturing Example 20.240.51 Manufacturing Example 30.240.49 Comparative Manufacturing Example 10.230.23 Comparative Manufacturing Example 20.220.25

[0081] Referring to Table 5, a significant difference in skin elasticity was observed between the comparative and manufactured examples. Considering the dose-dependent nature, this change is likely related to the application of ceramide. The above results confirm that a cosmetic composition containing beet root extract maintains high skin elasticity and exhibits an excellent skin elasticity-improving effect.

[0082] Skin elasticity is influenced by various factors, including the extracellular matrix and collagen fibers. Since extracellular matrix proteins and natural moisturizing factors that influence skin elasticity are synthesized by dermal fibroblast cells, glucosyl ceramide influences the proliferation of human fibroblasts and the synthesis of extracellular matrix proteins such as collagen and fibronectin.

[0083] Glucosyl ceramide, found in beet root extract, can increase fibronectin production and mRNA levels in human dermal fibroblasts. Fibronectin, an extracellular matrix protein, is produced by fibroblasts and exists in the matrix between collagen and elastic fibers in the dermis. It can bind to collagen, heparin, and other cells, and plays a crucial role in dermal elasticity, shape, and wound healing. Glucosyl ceramide can help maintain proper skin structure and maintain skin elasticity by promoting fibronectin production in fibroblasts.

[0084] [Experimental Example 4] Skin Irritation Test

[0085] Skin irritation tests were conducted on the backs of adult men and women aged 20 to 55 years. To ensure consistent measurement conditions across all subjects, the test areas were kept clean and dry. The skin was allowed to rest for at least 30 minutes in a constant temperature and humidity (22±2°C, RH 40-60%) before testing.

[0086] The test area was wiped with 70% ethanol, dried, and then 25 μl of each of Manufacturing Examples 1 to 3 was dropped into the Finn Chamber and placed on the subject's back and fixed. The patch was removed after 24 hours. After removing the patch, the test area was marked with a marking pen and observed after 30 minutes, 24 hours, and 48 hours.

[0087] - Visit 1 (Day 0, Test Start Date)

[0088] Subjects suitable for the study were selected based on the subject selection and exclusion criteria, and the subjects' skin condition was checked, after which the test was conducted according to the test method.

[0089] - Visit 2 (day 1, 30 minutes after patch removal)

[0090] Visual evaluation and photography were conducted to determine skin reactions according to the test method.

[0091] - Visit 3 (2 days, 24 hours after patch removal)

[0092] Visual evaluation and photography were conducted to determine skin reactions according to the test method.

[0093] The evaluation was performed 30 minutes, 24 hours, and 48 hours after removal of the patch, and the skin reaction was classified into irritation levels according to the evaluation criteria of the International Contact Dermatitis Research Group (ICDRG) in Table 6 below.

[0094]

[0095] International Contact Dermatitis Research Group (ICDRG) criteria

[0096] As a result of the test, no irritation was observed for Manufacturing Examples 1 to 3 at 30 minutes, 24 hours, or 48 hours after patch removal. The average skin reactivity score was 0.00, and Manufacturing Examples 1 to 3 were judged as non-irritating according to the judgment criteria of the skin patch test.

[0097] [Experimental Example 5] Itching Test

[0098] A skin itching test was conducted on 50 male and female adult volunteers aged 20 to 55 years with atopic dermatitis. The participants were randomly divided into five groups of 10 each. Equal amounts (by mass) of Preparation Examples 1 to 3 and Comparative Preparation Examples 1 to 2 were applied to the entire face. After 6 hours, the subjects were videotaped for 1 hour before and after application to observe the frequency of scratching. The results are shown in Table 7 below.

[0099] Manufacturing example 1178 after application of conductive coating Manufacturing example 2135 Manufacturing example 32014 Comparative manufacturing example 11413 Comparative manufacturing example 21513

[0100]

[0101] Referring to Table 7, patients with skin diseases who applied Preparation Examples 1 to 3 containing beet root extract showed a significant decrease in the number of times they scratched their skin compared to patients with skin diseases who applied Comparative Preparation Examples containing no or a small amount of beet root extract.

[0102] Therefore, it can be confirmed that the cosmetic composition containing the beet root extract of the present invention exhibits an excellent skin itching improvement effect. However, since Manufacturing Example 1 is a mist formulation, Manufacturing Example 2 is a lotion formulation, and Manufacturing Example 3 is a cream formulation, the degree of efficacy may vary depending on the typical skin application amount.

[0103] A cosmetic composition comprising a beet root extract according to one embodiment of the present invention exhibits excellent skin moisturizing effects, improved skin elasticity, strengthened skin barrier, and alleviated itching. Furthermore, as a cosmetic composition using natural ingredients to reduce skin irritation caused by various chemicals, it is non-irritating and thus effective for use by those with sensitive skin.

[0104] Although the present invention has been described with reference to limited embodiments and drawings, it is not limited to the embodiments described above, and those skilled in the art will appreciate that various modifications and variations may be made based on this disclosure. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims set forth below, but also by equivalents thereof.

[0105] The present invention relates to a cosmetic composition for improving skin condition, comprising a beet root extract, and more particularly, to a cosmetic composition for enhancing skin hydration, improving skin elasticity, and alleviating skin itching, comprising a beet root extract.
