Description

Cosmetic composite with anti-pollution heavy metal resistance

Technical Field

The invention relates to the field of cosmetics, in particular to a cosmetic compound with anti-pollution and heavy metal resistance.

Background

The human skin is used as a body part directly exposed to the external environment, is a protective film for protecting important organs of the human body, and plays a role in regulating water evaporation and protecting the body from external infection. However, excessive ultraviolet rays, contaminated environments, etc. induce skin irritation, resulting in skin aging.

Among such skin irritants, fine dust, yellow sand, and haze mixed with harmful substances such as heavy metals, which have been induced by recent industrial development, are the main causes of skin aging and skin problems. The heavy metal refers to mercury, cadmium, lead, copper and the like with the density of more than 4g/cm³Generally, the metal(s) of (1) is (are) incorporated into a substance in the human body to form an organic complex which is not easily decomposed when inhaled, and is not rapidly discharged from the body, and is accumulated on internal organs such as the liver and kidney, or bones. Long-term heavy metal inhalation can cause symptoms of quadriplegia, dyskinesia skin pigmentation and keratinization, toenail, heel and hair atrophy, reproductive dysfunction, abnormal growth, hypoevolutism, and immunologic hypofunction. Environmental hazardous substances are considered one of the most harmful environmental problems to health, and are strongly linked to skin diseases (rare. heavy metal pollution health risk assessment and regulation research [ D)]University of Nanjing, 2011.). Harmful heavy metal dust and the like are subjected to chemical reaction in the atmosphere to generate Nitrogen Oxide (NO) and sulfur oxideHarmful substances such as chemical compounds (SO) increase inflammatory substances of the skin, and may cause skin problems such as allergy. In addition, the particle size of heavy metals is below 2 ㎛, which is much smaller than that of ordinary dust (average size is above 20 ㎛). The fine dust containing the heavy metals can easily enter the deep layer of skin pores because of small particles, and skin inflammation and skin sensitivity are easily caused if the fine dust invading into the skin can not be cleaned.

Clinically, if harmful substances in the environment directly contact skin, allergic reaction and stimulation can be caused, contact dermatitis is easy to generate, meanwhile, moisture in the skin can be taken away by dry yellow sand, so that dry skin, cutin, pruritus, yellow sand pox, allergy and the like are caused, the problems are not rare, and corresponding treatment and countermeasures are still unclear. Heavy metals, fine dust, yellow sand and the like, which are harmful substances, are considered as stresses in the skin, and these stresses are generated under the influence of free radicals. Free radicals (Free radiation) refer to atoms or groups with unpaired electrons that lose a pole upon interaction with other molecules, these groups being in a very unstable state, in order to "treat" themselves, and to rob a pole from the surrounding healthy molecules (korean journal of dermatology 7(2): 51-62). In this process, more free radicals are formed and the tissue is damaged. Since such radicals are easily reactive with living bodies, if they are not removed from the human body, oxidative stress (oxidative stress) is induced, leading to collagen and the like cleavage and an increase in MMP-1 activity, and finally, reduction in skin moisture and accelerated aging.

Detailed Description

For the purpose of enhancing the understanding of the present invention, the following detailed description of the present invention will be given in conjunction with examples and drawings, which are provided for the purpose of illustration only and are not intended to limit the scope of the present invention.

Preparing dried burdock and water shield, adding 10 times of 70% (w/w) ethanol water solution, extracting at 60 deg.C for 5 hr, sieving with 250 mesh sieve, and filtering with 0.3 ㎛ filter paper plate. The filtrate was concentrated under reduced pressure using a vacuum concentrator (EYELA, N-1000, Japan) to obtain dry powders as control 1 and control 2. The raw materials were mixed according to the following table, and examples 1 to 5 were produced according to the above-described method.

Cytotoxicity evaluation test of the Complex

In order to evaluate toxicity in the cells of the 2 control groups and the 5 examples, the cell survival rate was determined by the MTT assay method. MTT assay is an experimental method widely used in the detection of cytotoxicity or cell proliferation by measuring the number of living cells, and is based on the principle that succinate dehydrogenase (or mitogenic dehydrogenase) in mitochondria of living cells can reduce MTT (3- [4, 5-dimethylthiozole-2-yl ] -2, 5-diphenyltetrazolium bromide), which is a water-soluble yellow salt, to a water-insoluble blue color and deposit in cells, whereas dead cells do not have such a function. The resulting crystalline formazan (formazan) is generally dissolved in dmso (dimethlysulfoxide) and then the absorbance is measured. Specifically, a 24-well multi plate (corning) was inoculated with 1ml each of 10% bovine serum-containing DMEM medium and keratinocytes (HaCaT) at a density of 1.5X105 cells/well, and the medium was changed to a serum-free medium after 24 hours of culture. Samples with different concentrations were added to serum-free medium for 24 hours after treatment. Thereafter, the medium was removed, treated with 0.25mg/ml MTT solution, and allowed to react at 37 ℃ for 4 hours. The MTT crystalline formazan was dissolved by adding 1ml of DMSO to the cells from which the MTT solution was removed, and the absorbance was measured at 570nm, and the cell viability was calculated according to the following formula.

The control group was tested without the addition of sample. The results of cytotoxicity are shown in tables 1 to 2 and FIGS. 1 to 7.

[ TABLE 1 ]

[ TABLE 2 ]

And (4) conclusion: the cell viability of the control 1, control 2 and examples 1 to 5 was close to 100% at all treatment concentrations between 1 to 250ug/ml, and no toxicity was observed.

Efficacy test of the Compound for protecting cells against heavy metals

In order to evaluate the efficacy of protecting cells against heavy metals, the degree of recovery of cell viability was determined for 2 representative heavy metals arsenic (As) and cadmium (Cd) contained in the dust particles. The efficacy of protecting cells against heavy metals was confirmed by MTtassay, which is an experimental method widely used in the detection of cytotoxicity or cell proliferation by measuring the number of living cells, based on the fact that succinate dehydrogenase (or mitochondal dehydrogenase) in mitochondria of living cells enables water-soluble yellow salt MTT (3- [4, 5-dimethylthiodiazol-2-yl) to be soluble in water]2,5-diphenyl tetrazolium bromide) to a water-insoluble blue color and deposited in the cells, whereas dead cells do not have this function. The resulting crystalline formazan (formazan) is generally dissolved in dmso (dimethlysulfoxide) and then the absorbance is measured. The specific experimental protocol was as 1.5X10 in a 24 well Multi plate (corning)⁵cells/well were inoculated at a density of 1ml each with DMEM medium containing 10% bovine serum and keratinocytes (HaCaT), and 24 hours later, the medium was changed to serum-free medium. Heavy metals arsenic (As) and cadmium (Cd) are added into a serum-free culture medium, and samples with different concentrations are respectively treated and then cultured for 24 hours. Thereafter, the medium was removed, treated with 0.25mg/ml MTT solution, and allowed to react at 37 ℃ for 4 hours. DMSO was added to the cells from which the MTT solution was removed, MTT crystalline formazan was dissolved, and the absorbance was measured at 570nm, and the cell viability was calculated according to the following formula.

The results are shown in tables 3 to 4 and FIGS. 8 to 9.

[ TABLE 3 ]

[ TABLE 4 ]

As a result: different samples are used for 2 heavy metals CdCl₂, As₂After the treatment of O3, the survival rate of cells is increased, compared with the effect of the single use of the burdock or water shield extract, the effect of the mixture of the burdock and the water shield extract is better, and the effect of protecting the cells from the damage of the harmful factors such as heavy metal is the best in example 3.

Testing of the anti-fouling efficacy of the composite

To evaluate the efficacy against contamination, Benzopyrene (Benzopyrene) of PAHS, a representative environmental contamination mutagen, which has an effect on DNA damage, inflammation, ROS production, and MMP-1 activity, was used as a contamination source. Thus, contaminants due to benzopyrene are produced, inflammation and aging are induced by increasing the expression of AhR (aryl Hydrocarbon receptor) and inflammatory cytokine (IL-1 α) which act as environmental and chemical stimuli and immune responses to link the environment, and the expression of CYP (Cytochrome P450)1a1, which is one of enzymes required for metabolism of foreign substances out of the body, is increased to produce an aged state in a harmful environment, and then the anti-pollution efficacy is determined by effectively reducing AhR, CYP1a1, and IL-1 α genetic factors. The specific experimental protocol was as 1.0X10 in a 6 well Multi plate (corning)⁶cells/well were inoculated at a density of 2ml each with 2ml of a DMEM medium containing 10% bovine serum and keratinocytes (HaCaT), and cultured for 24 hours. One day later benzo (a) pyrene (Wako,020-₂Incubate in the incubator for 30 minutes. After removal of the medium, 2ml of fresh serum-free medium was added, the sample was added, in CO₂Constant temperature boxThe culture was carried out for 4 hours. QIAzol was treated in cultured cells after washing with PBS buffer^®(QIAGENL^®USA), using the manufacturer (QIAGENL) after cell lysis^®) The provided procedures isolate RNA. Using qubits^®The isolated RNA 를 was quantified by fluorometer with RNA BR Assay kit, and cDNA was synthesized for Real-time fluorescent quantitation (Real-time PCR). cDNA Synthesis Kit (qPCRBIO cDNAsynthesis Kit, PCRBIOS systems, London, UK) was used for cDNA Synthesis, and experiments were performed according to the Kit method. Real-time fluorescent quantitation (Real-time PCR) the genetic factor amplification product was quantitatively analyzed using the Real-time PCR Kit (2x qPCRBIO SyGreen Blue mix Lo-ROX, PCRBIOS, London, UK).

Ahr, Cyp1A1, IL-1 α, β -Actin primers used in PCR were synthesized by cosmogenetech (Korea) and the primer sequences are shown in Table 5.

[ TABLE 5 ]

Primer and method for producing the same

The cDNA synthesis reaction conditions were Ahr, Cyp1A1, IL-1. alpha. and. beta. -Actin were all reacted at 42 ℃ for 30 minutes and 85 ℃ for 10 minutes. The positive control group used Resveratrol (Sigma, R5010), a well-known antioxidant. The results of the gene expression are shown in tables 6 to 7 and FIGS. 10 to 11.

[ TABLE 6 ]

[ TABLE 7 ]

As a result: resveratrol, used as a positive control group, is one of phytoalexins, an AhR inhibitor and an antioxidant substance that prevents transcription of CYP1a 1. Compared with Resveratrol (Resveratrol) as a positive control group, the burdock extract and water shield extract alone and all the examples have better inhibition capability on the expression of AhR and CYP1a1, wherein the inhibition capability of example 3 on the expression of AhR and CYP1a1 is the most excellent.
