Description

Cosmetic composition containing Oriental Herb Fragrance Active Component Limonene for Skin Benefit Ingredient}

The present invention relates to a composition for skin regeneration, wrinkle improvement, antioxidant, anti-inflammatory or skin whitening.

Collagen is a major matrix protein produced by skin fibroblasts and is present in extracellular epilepsy.The main functions are the skin's mechanical strength, the resistance of connective tissue and the adhesion of tissue, the support of cell adhesion, cell division and differentiation. Induction of growth or wound healing). This collagen is reduced by age and light aging by ultraviolet irradiation, which is known to be closely associated with wrinkle formation of the skin. In addition, in recent years, extensive research on skin aging has revealed the important function of collagen in the skin.

Active ingredients are known that promote collagen synthesis and exhibit wrinkle improvement. For example, retinoic acid, transforming growth factor (TGF) [non-patent document 1], protein derived from animal placenta [patent document 1], betulinic acid (patent document 2), and chlorella extract [ Patent Documents 3 and 4 are known as collagen synthesis promoting substances. However, the active ingredients are limited in the amount of use due to safety problems such as irritation and redness when applying the skin, or there is a problem in that the effect of improving the skin function can not be expected by substantially promoting collagen synthesis of the skin.

On the other hand, free radicals introduced from outside the living body or generated in the living body cause many problems such as promoting aging of the living body or generating cancer. Therefore, many researches and developments on antioxidants that inhibit oxidation by active oxygen have been made. Antioxidants are widely distributed in copper and plant systems, and phenolic compounds, flavonoids, tocopherols, vitamin C, selenium, and the like, which are widely contained in fruits and vegetables, are known. However, antioxidants present in nature are not expected to have a substantial enough effect on skin application. Therefore, many synthetic antioxidants having excellent antioxidant power and low cost are used, but their use is limited due to safety concerns such as human side effects.

In addition, inflammation is an immune response of the human body in response to a wound or disease, and oxidative stress such as ultraviolet rays, free radicals, and free radicals activates inflammatory factors and causes various diseases and aging of the skin. Vascular activating polypeptides, such as kinin, plasmin or complement, act as vasodilation, contraction and chemotaxis, as well as lymphokahs such as interleukin-6 (IL-6). Phosphorus and arachidonic acid are responsible for the inflammatory response. Arachidonic acid is metabolized to prostaglandin or leukotrienes, which are inflammatory mediators, through two pathways, cyclooxygenase or lipooxygenase, to mediate various inflammatory reactions.

On the other hand, the anti-inflammatory agent is to remove the inflammatory source, reduce the biological response and symptoms in order to eliminate inflammation. The substances used for anti-inflammatory purposes until now are nonsteroidal flufenamic acid, ibuprofen, benzydamine or indomethacin, and prednisolone as a steroid system. Or dexamethasone. In addition, allantoin, azene, or hydrocortisone are known to be effective in anti-inflammatory, but these substances have a problem in that the amount of the use is limited due to the safety of the skin, or the effect is insignificant, so that the anti-inflammatory effect can not be expected. have.

In addition, it is a general desire to have white and fair skin. The color or brightness of the skin is genetically determined by the concentration and distribution of melanin in human skin, but is also influenced by environmental or physiological conditions such as solar ultraviolet light, fatigue or stress. Melanin is a type of amino acid tyrosine (tyrosine) enzymes tyrosinase (tyrosinase) acts as a catalyst to be sequentially converted to dopa (DOPA) and dopaquinone (dopaquinone) and then made through a non-enzymatic oxidation reaction. As such, the pathway through which melanin is made is known, but it is still unknown in detail what causes the tyrosinase to be triggered in the mechanism that induces melanin synthesis.

On the other hand, as a known whitening component, substances that inhibit tyrosinase enzyme activity such as kojic acid or arbutin, hydroquinone, vitamin C (L-Ascorbic acid) or derivatives thereof and various There is a plant extract. By inhibiting the synthesis of melanin pigments, they can brighten skin tone and realize skin whitening, and can also improve skin hyperpigmentation such as blemishes and freckles due to ultraviolet rays, hormones or heredity. However, when the skin is applied, there are limitations on the amount of use due to safety problems such as irritation and redness, or there is a problem that a substantial effect can not be expected due to a slight effect.

Therefore, it is safe for the living body, the active ingredient is stable, and above all, the skin regeneration, anti-wrinkle, antioxidant, anti-inflammatory or whitening activity is superior to the existing skin regeneration, anti-wrinkle, antioxidant, anti-inflammatory or whitening substance. There is an urgent need for the development of these components.

The inflammation is one of biological tissue's defense response to a certain stimulus, and refers to a complex lesion involving three kinds of tissue degeneration, circulatory disorder and exudation and tissue proliferation. More specifically, inflammation is part of innate immunity and, as in other animals, human innate immunity recognizes patterns of cell surfaces that are specific to pathogens. Phagocytes recognize cells with such surfaces as nonmagnetic devices and attack pathogens. If the pathogen breaks through the body's physical barrier, an inflammatory reaction occurs. Inflammatory reactions are nonspecific defenses that create a hostile environment against microbes that have invaded the wound. In inflammatory reactions, when wounded or an external infectious agent enters the body, white blood cells in the early stages of immune response rush to express cytokines. Therefore, the expression level of cytokines in cells is an indicator of inflammatory response activation. Examples of skin diseases associated with inflammation include atopic dermatitis, psoriasis, radiation, chemicals or burns, and erythematous diseases; Itching due to acid burns, bullous skin disease, thyroid disease or allergies; Inflammatory hair loss such as seborrheic eczema, rose acne, vulgaris ulcer, polymorphic exudative erythema, nodular erythema, glansitis, vulvitis or alopecia areata; Cutaneous T-cell lymphomas, and the like.

Example  1: effect of increasing the total amount of collagen

The substances of Table 1 were added to the culture solution of human-derived fibroblasts to measure the total amount of collagen at the cellular level. The total amount of collagen was quantified using a PICP EIA kit (Procollagen Type I C-Peptide Enzyme ImmunoAssay KIT). To evaluate the cytotoxicity at 10 ppm, 1 ppm, 0.1 ppm, 0.01 ppm, and 0.001 ppm of the concentration of the test substance in human-derived fibroblasts before the experiment (method of culturing fibroblasts for MTT test [Reference: Mossman T. (1983) Rapid Colorimetric Assay for Cellular Growth & Survival: application to proliferation & cytotoxicity assays.Journal of Immunological Methods 65, 55-63].

In the experiment, the final concentration of the compound of Formula 1 was 1 ppm and 10 ppm, respectively, and each sample was added to the culture medium of human fibroblasts and cultured for 1 day, and then the culture medium was taken and collagen at each concentration was collected using PICP EIA kit. The total amount was measured at 450 nm using a spectrophotometer. For comparison of the effects, the total amount of collagen was measured in the same manner with respect to the fibroblast culture medium (control) and the sample to which vitamin C was added at a final concentration of 52.8 ppm. The total amount of collagen was measured as UV absorbance, and the increase rate of the total amount of collagen was calculated as the ratio of total amount of collagen relative to the control group, and the results are summarized in Table 1 below.

Increase effect of total collagen (repeated number = 3) sample Absorbance average Collagen Growth Rate (%) Compound of Formula 1
(1 ppm) 478 104 Compound of Formula 1
(10 ppm) 504 110 Control
(No addition) 456 - Vitamin c
(52.8 ppm) 552 121

As can be seen from the results of Table 1, the compound of Formula 1 (10 ppm) is similar to the effect at a much lower concentration than vitamin C (52.8 ppm) is known to have collagen synthesis ability, stable as a natural substance, Formula 1 It was found that the compound can be used as a substance for skin regeneration and wrinkle improvement.

Example  2: melanin total reduction effect

The whitening effect was confirmed by measuring the total amount of melanin at the cellular level by adding it to the culture medium of B-16 mouse melanoma cells (Lotan R., Lotan D. Cancer). Res . 40: 3345-3350, 1980). Before the experiment, rat melanoma cells were evaluated for toxicity, and non-toxic concentrations were selected for whitening evaluation.

The final concentration of the compound of Formula 1 was 5 ppm, 10 ppm, 20 ppm in the culture medium, and arbutin, a control group, was added to the medium so as to be 200 ppm, and treated with B-16 melanoma cells, respectively, and cultured for 3 days.

Then, cells were trypsin-treated and removed from the culture vessel, centrifuged, and melanin was extracted. The detached cells were added with 1 ml of sodium hydroxide solution (1 N concentration), boiled for 10 minutes to dissolve the melanin, and the absorbance was measured at 400 nm using a spectrophotometer to measure the amount of melanin produced.

The melanin amount was measured by the absorbance of the unit cell count (10 ⁶ cells), the total melanin relative to the control group was calculated as the inhibition rate (%) and the results are summarized in Table 2. The experiment was repeated three times.

Reduction effect of total melanin at the cellular level with different concentrations sample Melanin % Inhibition Control group (no addition) 0.071 - Control 1: Arbutin (200 ppm) 0.039 45 Compound of Formula 1 (20 ppm) 0.047 33 Compound of Formula 1 (10 ppm) 0.052 27 Compound of Formula 1 (5 ppm) 0.068 4

As can be seen from the results in Table 2, the compound of formula 1 is reduced compared to the arbutin (200 ppm) known as a whitening material, the total amount of melanin is reduced for the melanoma cells of the cultured mice even at a low concentration can be used for whitening purposes I could see that.

Example  3: antioxidant effect Free radical  Erasure rate

Free radical scavenging activity was measured to confirm antioxidant activity. Free radical scavenging activity was measured using DPPH. DPPH was purchased from Sigma Co., Ltd, USA. First, a 1.5 mM (0.06 mg / ml) standard DPPH solution was made. Ethanol was added to the ascorbic acid, an antioxidant, as a compound of Formula 1 and a reference material, respectively, to prepare samples at concentrations of 50 ppm, 25 ppm, 12.5 ppm, 6.25 ppm, and 3.125 ppm. Then, the sample and the standard DPPH solution were added in the same ratio and stirred well, followed by reaction at 37 ° C. for 30 minutes, and absorbance at 520 nm. At this time, ethanol was added instead of the sample as a control. The free radical scavenging ability was obtained from IC ₅₀ , which is a half maximal inhibitory concentration, and the results are shown in Table 3 below. IC ₅₀ is a common method of expressing free radical scavenging ability as a concentration of ascorbic acid and a compound of formula (1) required to remove 50% of free radicals from an additive-free control.

Free radical scavenging rate (IC ₅₀ ) sample Free radical scavenging rate (ppm) Ascorbic acid 8 Compound of Formula 1 58

As can be seen in Table 3, the compound of Formula 1 has a lower activity than the ascorbic acid (Vitamin C), which is a representative strong antioxidant, but is stable as well as an excellent level of antioxidant effect as a natural substance and used as an antioxidant potency material. It is understood that the following is suitable.

Example  4: anti-inflammatory effect NO  Generation suppression effect

In order to confirm the anti-inflammatory effect and skin trouble relieving effect, the experiment was conducted to inhibit the formation of nitric oxide (NO) by GRIESS method using RAW264.7 cell line (ATCC number: CRL-2278).

Specifically, RAW264.7 cells, which are macrophages of mice, were passaged several times, placed in a 24-well plate to enter 3 × 10 ⁵ cells in one well, and then cultured for 24 hours. Subsequently, the cell medium containing diluting the compound of Formula 1 at a concentration of 1% (10 mg / ml), 0.1% (1 mg / ml), 0.01% (0.1 mg / ml), 0.001% (0.01 mg / ml) Replaced with. At this time, 0.001% of L-NMMA (L-NG-Monomethylarginine), a NO-producing inhibitor, was treated with a positive control group and incubated for 30 minutes.
