Description

A composition for external application for skin containing aloe and seaweed extract as an active ingredient {EXTERNAL PREPARATION FOR SKIN COMPRISING ALOE AND MARINE ALGAE EXTRACTS}

The present invention relates to a composition for external application for skin having an effect of improving skin moisturizing, reducing temperature, soothing, and improving elasticity.

Skin is largely divided into three layers: epidermis, dermis, and subcutaneous fat tissue in order from the outside, and functions to protect the human body from physical and chemical stimulation by the external environment. The skin plays an important role, such as controlling the evaporation of water, which constitutes most of the human body, out of the body, so that various physiologically active substances necessary for the human body can be transported normally. In particular, the epidermis is located on the most surface of the skin and determines skin texture, moisture, and skin color. Healthy and beautiful skin is shiny and smooth on the surface, has good elasticity and delicate skin texture. The stratum corneum of healthy skin contains 15 to 20% of moisture, and when the moisture falls below 10%, it becomes dry, gloss and elasticity decreases, wrinkles increase, and skin looks aged.

As aging progresses, the boundary between the epidermis and the dermis becomes flat, and the area of the boundary decreases, making it more susceptible to external damage and reducing the supply of skin nutrition. As the cell cycle decreases, the lumpy keratinocytes on the skin surface not only give a rough and dull skin feeling, but as the dermal thickness decreases, collagen is denatured and elastic fibers are destroyed, leading to appearance changes such as wrinkles, dryness, and aging.

In line with the social demand to slow down this skin change phenomenon and create a young and refreshing appearance, recent cosmetic research trends are focusing on the development and commercialization of new ingredients. Since moist and elastic skin shows a bright and flexible image, cosmetics with various effects and characteristics such as moisturizers, essences, ampoules, etc. have been consistently popular and developed, which is also evidence that people recognize the importance of skin care.

Criteria for selecting test subjects

In order to evaluate the composition for external application for skin of Examples and Comparative Examples, 22 subjects were selected according to the selection criteria shown in Table 2 below.

Test Example 1: Evaluation of skin moisturizing effect

In order to check the skin moisturizing effect according to the use of the composition for external application for skin of Example 1, the skin moisturization degree before and after the use of the composition was measured for 22 test subjects selected according to the selection criteria shown in Table 2.

The evaluation subjects were washed and washed with the same detergent for 30 minutes and then stabilized in a constant temperature and humidity room (temperature: 22±2℃, humidity: 50±5%), and the evaluation proceeded.

The same test staff applied the same amount of the composition of Example 1 to the right lower forearm of all subjects. After 15 minutes, remove the mask pack, and use a cooler (ELECTRIC AIR COOLER BKCF-16R01K, Bokuk, Korea) into which a refrigerant is added to the artificial cold air at a temperature of 17±2℃ in natural air mode at a distance of 50cm from the test site for 20 minutes. Applied during. Epsilon E100 calculates the moisture of the skin surface in contact with the sensor as the value of Epsilon(ε), and the higher the moisture content of the skin, the greater the brightness of the image result and the blue part changes to white. The same test staff measured the right lower forearm of all test subjects, and analyzed the change in skin moisture using Epsilon E100 Software Installer V2, an analysis program exclusively for Epsilon E100. Example 1 Compared to before use of the composition, as the measured value increases, it means that there is an effect of maintaining skin moisture in an artificial cold wind environment.

The instrument measurement was performed on the right lower forearm as the test site before using the composition of Example 1, immediately after one use, and after applying artificial cold wind for 20 minutes.

The measurement results are shown in Tables 3 to 5 and FIGS. 1 and 2.

As shown in the skin moisturizing evaluation results, it can be seen that compared to before using the composition in Example 1, it was 348.31% immediately after one use and 256.65% after application of artificial cold wind. In addition, it was confirmed that the skin moisturizing degree is statistically significant after using the composition of Example 1 (p<.001), so it is effective in maintaining skin moisturization.

Test Example 2: Evaluation of skin temperature reduction (soothing irritation by heat)

Test Example 2-1: Thermal imaging camera

A thermal imaging camera (FLUKETi105 Thermal Imager, Fluke, Inc., USA) was used to evaluate the soothing effect of skin irritation caused by heat.

The evaluation subjects were washed and washed with the same detergent for 30 minutes and then stabilized in a constant temperature and humidity room (temperature: 22±2℃, humidity: 50±5%), and the evaluation proceeded.

The same test person used an infrared irradiator (IR300, Daekyoung Co., Kyungki, Korea) to divide all the test subjects' facial areas into Example 1 composition-applied area and non-applied area, and then the intensity of 250 W/㎠ at a distance of 10cm Heat was applied for 5 minutes, and after waiting for 20 minutes, the subject's face was measured using a thermal imaging camera. The photographed image was measured for the change in skin temperature of the applied and uncoated areas of the test substance using the dedicated analysis program SmartView 3.3.

The thermal imaging camera detects infrared rays emitted by the surface temperature of an object and calculates the temperature based on the data, and the unit of measurement is ℃. Compared to the non-applied area of the test substance, the more significantly (p<.05) the change in the measured value of the applied area decreases, the more effective it means to have a skin cooling effect (decrease in temperature). Instrument measurements were made before use of the test substance (after heating) and immediately after one use for 15 minutes.

The measurement results are shown in Tables 6 to 9 and FIGS. 3 and 4.

As a result of analyzing the degree of improvement of the skin cooling effect (temperature decrease) on the face area using a thermal imaging camera, the skin temperature was 22.66% (average average) on the applied area immediately after one use for 15 minutes compared to before (after heating) the test substance use (after heating). -8.08 ℃), 8.78% (average -3.14 ℃) decreased in the uncoated area. In addition, immediately after one use of the unapplied area of the test substance △ Immediately after one use of the applied area compared to the skin temperature △ The skin temperature was statistically significant (p<.001), and the test substance was affected by the skin cooling effect (temperature decrease). It can be seen that there is a significant effect.

In addition, in order to check the immediate skin soothing effect of the composition of Example 1 by thermal stimulation, the same test person measured the facial areas of all subjects, and the photographed image was viewed on the left side using a dedicated analysis program SmartView 3.3. The change in skin temperature of the site was analyzed. Instrument measurements were performed before use of the test substance, after heating (after 20 minutes), and immediately after one use.

Measurement results are shown in Tables 10 to 12, and FIGS. 5 and 6.

As a result of analyzing the degree of improvement of the immediate skin irritation cooling effect by the heat of the left cheek area using a thermal imaging camera, △, which indicates the change in skin temperature, immediately after one use of the test substance compared to after the skin temperature warms (after 20 minutes) 271.07% showed a decreasing change. In addition, compared to after heating (after 20 minutes), △skin temperature is statistically significant immediately after one use of the test substance (p<.001), so the test substance has a significant cooling effect against immediate skin irritation caused by heat. Was confirmed.

Test Example 2-2: Whole eye imaging system

In order to evaluate the soothing effect of skin irritation caused by heat, an anterior ocular imaging system VISIA-CA (VISIA Complexion Analysis, Canfield Scientific, Inc., USA) and an image analysis program (Image J, National Institutes of Health, USA) were used.

The evaluation subjects were washed and washed with the same detergent for 30 minutes and then stabilized in a constant temperature and humidity room (temperature: 22±2℃, humidity: 50±5%), and the evaluation proceeded.

The same test person used an infrared irradiator (IR300, Daekyoung Co., Kyungki, Korea) to divide all the test subjects' facial areas into Example 1 composition-applied area and non-applied area, and then the intensity of 250 W/㎠ at a distance of 10cm Heat was applied for 5 minutes, and after waiting for 20 minutes, photographs were taken.

The anterior eye imaging system VISIA-CA measured the facial areas of all subjects by the same test person in uniform lighting and the same position for consistent imaging. In order to secure the hairline of the subject's forehead, the hair was fixed with a hairband, and then the same top gown was worn and the person sat on a chair, and the front of the face was photographed while the face was fixed to the top of the toolbar under the cage. The measured image can be extracted as L*, a*, and b* three values using an RGB color skin image using an image analysis program and an ICA (independent component analysis) algorithm, and the L* value is the brightness. ), a* value indicates hemoglobin detection, redness, b* value indicates melanin detection, and yellowness. As a value to measure the (immediate) soothing effect of skin irritation caused by heat of the test substance, a* value representing the redness of the skin was used for analysis, and the change in the measured value was significantly (p<.05) compared to before use of the test substance. As it decreases, it means that there is a soothing effect of (immediate) skin irritation by heat. The instrument measurement was performed before use of the test substance, after heating, and immediately after one use of the test substance for 15 minutes.

Measurement results are shown in Tables 13 to 15 and FIGS. 7 and 8.

The Δa* value representing the change in the redness of the skin showed a change of 69.84% reduction immediately after one use of the test substance compared to after heating (after 20 minutes). In addition, compared to after heating, the Δa* value was statistically significant immediately after one use of the test substance (p<.01), confirming that the test substance had a significant effect on the (immediate) skin irritation sedation effect caused by heat.

Test Example 3: Skin temperature reduction evaluation (physical irritation soothing)

In order to confirm the soothing effect of skin irritation caused by external physical factors, a tape stripping method and an ANTERA 3D (Miravex, Ireland) device were used.

The same test person in charge attached 18 mm tape (Scotch® Transparent Tape, 3M Company, USA) to the designated test site, applied the same pressure for 2 seconds, and then stripped in the same direction. Stripping was repeated 40 times using a new tape each time, and the measurement was carried out by dividing the area where the composition of Example 1 was applied and the area not applied.

The same test personnel measured both middle forearms (the test substance applied region, the uncoated region) of all subjects, and the same region was measured by overlapping the image measured before using the test substance for reproducibility of the measurement. The captured images were analyzed using Average CIE L*, a*, and b* values using ANTERA CS software, an exclusive software for ANTERA 3D. L* values are brightness and a* values are redness. , b* values indicate yellowness. As a value to measure the skin irritation soothing effect due to external stimulation (physical stimulation) of the test substance, a* value representing the redness of the skin was used in the analysis, and the change in the measured value of the applied area was significant compared to the non-applied area of the test substance. It means that there is a soothing effect on skin irritation caused by external stimuli (physical stimulus) as the amount decreases (p<. Instrument measurement was performed before use of the test substance (after stimulation) and immediately after use once for 15 minutes.

Measurement results are shown in Tables 16 to 19 and FIGS. 9 and 10.

The a* value, which represents the redness of the skin, decreased by 22.17% in the applied area and 11.31% in the non-applied area immediately after one use compared to before (after irritation) using the test substance. In addition, compared to the Δa* value immediately after one use of the unapplied area of the test substance, the Δa* value immediately after one use of the application site was statistically significant (p<.001), and the test substance was exposed to external stimuli (physical stimulation). It was confirmed that the soothing effect of skin irritation was significantly increased.

Test Example 4: Evaluation of skin elasticity resilience

Example 1 An ANTERA 3D (Miravex, Ireland) device was used to evaluate the effect of improving skin elasticity and resilience on the composition.

The same test person applied pressure to both forearms of all test subjects (the test substance applied region, the non-applied region) for 10 seconds with the same pressure probe, and then photographed it with ANTERA 3D. For reproducibility of the measurement, the test substance was measured before use. The same area was measured by overlapping the image. The photographed image was matched using ANTERA CS software, which is an exclusive software for ANTERA 3D, and then the matched measurement site was used for analysis. The measured value was analyzed for the Depressions medium value representing the depressed volume of the skin, and the unit of measurement was mm3. Compared to the non-applied area of the test substance, the significantly (p<.05) decrease in the change in the measured value of the applied area means that the elasticity of the skin is improved. Instrument measurements were performed before and immediately after use of the test substance.

Measurement results are shown in Tables 20 to 23 and FIGS. 11 and 12.

Test Example 5: Evaluation of adverse skin reactions

Observation of skin abnormalities such as erythema, edema, scaling, itching, stinging, burning, stiffness, and prickling at the test site And the grade was indicated when an adverse skin reaction occurred, and the results are shown in Table 24.

As shown in the table, it can be confirmed that no adverse reactions to allergic contact dermatitis or irritant contact dermatitis were observed after using the test substance in the test subject.

Test Example 6: Survey

A questionnaire survey was conducted on the characteristics of the test subject's general skin condition, the skin condition before and after using the test substance, and the feeling of using the test substance. One question on general skin condition characteristics and five questions on skin condition before and after use of the test substance were investigated using a multiple-choice type. In addition, in order to examine the feeling of use of the test substance, five questions were conducted using the satisfaction/dissatisfaction option.

The results of analyzing the characteristics of the general skin condition of the test subject are shown in Table 25, the results of the questionnaire survey on the skin condition before use of the test substance are shown in Table 26, and the results of the survey on the feeling of use are shown in Table 27. In addition, the results of the questionnaire survey on the skin condition after use of the test substance are shown in Table 28.

Taking the above results together, it can be seen that the composition according to the present invention can significantly increase the skin moisturizing effect, the skin soothing effect and the elastic resilience improvement effect due to heat and external physical stimulation. In addition, it can be seen that more than 80% of the test subjects are satisfied with the feeling of use, and in particular, it can be seen that the satisfaction of the skin moisturizing, cooling and soothing is high.
