Description

A cosmetic composition having excellent skin antioxidant and soothing effects, a cosmetic using the same, and a manufacturing method thereof

The present invention relates to a cosmetic which is excellent in skin antioxidant and soothing effects derived from natural plant ingredients using natural plant extract ingredients and the like and has an atopic dermatitis improvement effect, and a method for manufacturing the same.

The skin is a membrane that covers the outside of the body and performs various physiological functions to protect the body from environmental factors such as various external stimuli, obstacles, and dryness, thereby protecting and controlling internal organs and other internal organs. do.

However, as we age, the secretion of various hormones that control metabolism internally decreases, and the function and activity of immune cells are reduced. In addition, externally, the UV content in the sun's rays increases due to the destruction of the ozone layer, and excessive physical and chemical stimulation and stress caused by the increase of free radicals and active harmful oxygen as the environmental pollution is further deepened is the normal function of the skin. It damages the skin by promoting the generation of spots, freckles, etc., and aging of the skin due to deterioration, melanin deposition. In order to prevent skin aging and damage caused by these internal and external factors, and to maintain healthy and beautiful skin, physiologically active substances obtained from various animals, plants, microorganisms, etc. Efforts to maintain skin health by activating cells to promote skin metabolism are continuing, and cosmetics and external preparations for skin are being developed accordingly.

Atopy occurs mainly in infancy and is also called fetal fever, mainly due to a decrease in the content of ceramides in the stratum corneum. Although the cause of atopic dermatitis has not yet been clearly identified, it is presumed that it is caused by disturbance of the immune system.

In general, atopic dermatitis is dry as the moisture retention function of the stratum corneum is lowered, and as the skin barrier function is lowered, skin allergies etc. easily occur, causing severe itching, repeated recurrence, and dermatitis easily caused by various stimuli. do. In many cases, it worsens repeatedly at intervals of 1 to 2 weeks, and if not managed properly, it progresses to a subacute lesion of erythematous rash accompanied by exudation, and chronic lesions of lichenification that are thickened like leather.

The causes of atopic skin are largely divided into two. One is due to genetic causes. The skin barrier is due to the congenital lack of gamma-linoleic acid (GLA), which is an intercellular binding material that is the skin barrier. This is caused by the easy loss of moisture from the weak and surface of the skin. Other causes are environmental causes, which are caused by dry living environment, free radicals, bacteria, viruses, fungi, etc.

Due to atopic dermatitis, mast cells exhibit a degranulation state due to the release of allergic reaction-inducing substances such as histamine from intracellular granules [Gao ZG, et al., Biochem Pharmacol. 2009. Nov 5]. In addition, atopic dermatitis is reported to be highly likely to be an allergic disease in that it is accompanied by allergic rhinitis and asthma [de Meer G, et al., Pediatr Allergy Immunol. 2009. Nov 13].

Steroid drugs (corticosteroids) have excellent anti-inflammatory and immunosuppressive effects among the most commonly used therapeutic drugs, but long-term use may cause hair loss and skin atrophy, decrease skin pigmentation, and bacterial infection. It has side effects, such as acne, skin thinning and blood vessels exposed.

A lot of research and products are being developed on various atopic dermatitis improvement and/or prevention ingredients derived from natural materials using chemicals, and cosmetics that can be applied to various formulations and various application products while minimizing side effects such as skin troubles There is an increasing demand for it.

Referring to Tables 10 and 11, it was confirmed that, in the case of Examples 1 to 5, there was no adverse skin reaction while having an excellent feeling of use. In contrast, in Comparative Example 1, in the case of Comparative Example 1 using less than 9.5% by weight of the plant-extracted complex fermented product, compared with Examples 1 and 2, the soothing feeling in use is somewhat lowered, and the skin soothing effect is lowered. there was In addition, Comparative Example 2, in which the plant extract complex fermented product was used in excess of 15% by weight, had a problem in that the tester who caused skin troubles in the skin abnormality evaluation occurred. In addition, there was a problem in that the feeling of use was somewhat insufficient due to the lack of moisturizing power using less than 2.5% by weight of the complex oil, and the result of skin abnormality evaluation was poor. And, Comparative Example 3, in which the complex oil was used in excess of 5% by weight, showed a very poor feeling of use because the viscosity was too high.

Experimental Example 3: Human patch experiment

Separately from Experimental Example 1, a human patch experiment of the cosmetic of Example 1 was performed by requesting the Seowon Global Skin Clinical Center (experimental period of 5 weeks).

In the test, the IQ ultra chamber containing the sample was attached to the skin of the test subject's arm, etc., and then removed after 24 hours, and the results were read after 30 minutes and 24 hours. The subjects were adult males and females satisfying the criteria for selection of subjects in Table 5 (average age 23.6 years), and finally 32 subjects were selected.

The skin characteristics of the test subject are shown in Table 12 below.

As a result of the human patch test, Examples 1 to 5 showed that the average skin reactivity was non-irritating. However, in Comparative Example 2, in which the content of the complex fermented product of plant extraction was excessive, and Comparative Example 4, in which the complex oil content was used in excess of 5% by weight, the sticky feeling was too strong, there was a test subject that caused skin trouble.

Experimental Example 4: Investigation of atopic skin improvement effect

The clinical evaluation of the atopic skin improvement effect on the cosmetics of Examples 1 and 5 was measured. The following experiment was conducted on 15 children with atopic skin who visited the hospital and received treatment. The test sample was divided into right and left parts by a double-blinded test and applied to the whole body, but the use of other moisturizers and cosmetics that could affect the effect of the test sample was prohibited as much as possible. The effect after 1 week, 2 weeks, 3 weeks, and 4 weeks after application of the test sample is calculated according to Equation 2 by SCORing Atopic Dermatitis (SCORAD) measurement method, and the improvement rate is calculated according to Equation 3 and the results are shown in Table 15 below.

The control group in Table 15 did not include only the plant-extracted complex fermented product in Example 1, and the same amount was used for other compositions.

[Equation 2]

Improvement effect number = (by degree / 5) + (by intensity / 7) + (by subjective basis)

In Equation 2, the extent criteria are area = damaged area/100, and the intensity criteria are erythema (1 to 3 points), edema (1 to 3 points), exudation (1 to 3 points), Skin peeling (1 to 3 points), lichenification degree (1 to 3 points), and dryness (1 to 3 points) are the subjective criteria, and the subjective criteria are itchiness (1 to 10 points) and insomnia (1 to 10 points).

[Equation 3]

Improvement rate (%) = (0-week improvement effect value - measured week improvement effect value)/ (0-week improvement effect value)×100(%)

division 0 weeks 1 week 2 weeks 3 weeks 4 weeks Example 1 shame 72.5 58.8 53.4 39.1 28.8 improvement rate 0% 18.9% 26.3% 46.1% 60.3% Example 5 shame 72.5 59.0 53.8 39.8 29.9 improvement rate 0% 18.3% 25.6% 45.2% 57.8% control shame 72.5 60.7 54.8 49.0 38.5 improvement rate 0% 16.3% 24.4% 32.4% 46.9%

Looking at the measurement results in Table 15, when comparing Examples 1 and 5 with the control group, when atopic dermatitis of atopic-treated patients uses a cosmetic comprising a plant extract complex fermented product of the present invention, the improvement effect of atopic dermatitis is increase could be confirmed.

Experimental Example 5: Measurement of antioxidant activity

Antioxidant activity was measured by DPPH assay method. Specifically, after making a 100 uM DPPH ethanol solution, 190 μl of the DPPH solution and 10 μl of a sample diluted with methanol for each concentration were added, reacted at room temperature for 30 minutes, and absorbance was measured at 520 nm.

The control sample obtained the DPPH radical scavenging activity of the sample according to each treatment concentration compared to the control untreated group according to the formula below, and _{converted into a concentration IC 50} value corresponding to 50% scavenging activity, and is shown in Table 16 below. .

As a positive control, a synthetic antioxidant, Trolox, was used.

DPPH radical scavenging rate (%) = (Control-sample)/Control X 100 (%)

division IC ₅₀ (μg/ml) Trolox 47.04 Example 1 52.57 Example 5 46.25

Looking at the measurement results of the DPPH radical scavenging activity in Table 16, it can be seen that the cosmetics of Examples 1 and 5 have DPPH radical scavenging activity almost equal to or similar to that of the antioxidant Trolox, compared to Example 1 5 showed relatively better DPPH radical scavenging activity.

Experimental Example 6: Evaluation of cell viability

Human dermal fibroblast neonatal (hereafter, HDFn) ^{was inoculated into a 96-well plate at a concentration of 1×10 4} cells/well and then stabilized in a 37° C. incubator for 24 hours for stabilization. Thereafter, each sample was diluted and processed by concentration. In order to check the cell activity rate using MTT (3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide) reagent, the MTT solution was treated after 24 hours. After removing the sample after 2 hours, 150 μl of DMSO was added to each well to dissolve the formed formazan, and absorbance was measured and analyzed at 540 nm, and the results are shown in Table 17 below.
