Description

Composition with anti-pollution and anti-damage effects and skin care product thereof
Technical Field
The invention belongs to the field of cosmetics, and relates to a composition with an anti-pollution and anti-damage effect and a skin care product thereof.
Background
The constituents of PM2.5 are very complex and mainly classified into five types: water-soluble salts (sulfate, sodium salt, nitrate, ammonium salt, etc.), strongly toxic heavy metal elements (lead, copper, zinc, arsenic, etc.), organic substances (alkanes, aromatics, polycyclic aromatics, alkenes, quinones, etc.), low-toxic or nontoxic metal elements (sodium, magnesium, aluminum, iron, etc.), and microorganisms (bacteria, mold, actinomycetes, etc.), which are extremely harmful to the skin.
PM2.5, when contacted with the skin, causes toxic damage to keratinocytes. Firstly, keratinocytes release inflammatory factors IL-1 alpha and TNF-alpha, and activate NF-kB signal path to produce a large amount of inflammatory factors, such as IL-8 and COX2、PEG2VCAM-1, and the like, thereby causing immune cell recruitment and migration, and vascular reactions such as vasodilatation and permeability change, and finally causing acute phase reactions of red, swollen, painful and itchy skin inflammation; with the continuous accumulation of inflammatory factors, when the oxidative toxicity of air pollutants exceeds the capacity of the cell detoxification system, the oxidative toxicity is uncontrolledThe reactive oxygen species ROS can attack cellular lipid and protein, so that lipid peroxidation and protein oxidation are caused, and even mitochondrial dysfunction is caused, calcium ion disorder is caused, and abnormal apoptosis of cells is caused; the dysfunctional mitochondria can continuously generate a large amount of free radicals to induce the uninterrupted release of inflammatory factors to cause chronic inflammatory reaction, and if the damaged mitochondria can not be removed in time, the damaged mitochondria can not only cause serious damage to skin for a long time, such as sensitive, abnormal desquamation and premature aging, but also can cause mitochondrial dysfunction diseases such as neurodegenerative diseases, coronary heart diseases, diabetes and the like. In addition, since the inflammatory reaction reduces or partially removes the thiol groups in the skin, the reduction of thiol groups increases tyrosinase activity, possibly causing skin pigmentation; and polycyclic aromatic hydrocarbon carried by PM2.5 can activate aromatic hydrocarbon receptor (AhR), and further induce POMC to promote synthesis of melanin, and form persistent color precipitate.
At present, raw materials for resisting pollution injury continuously appear, but most of the raw materials only aim at eliminating acute inflammation, and the raw materials are difficult to play a role in injury caused by chronic inflammation.
Mitochondria are the "energy factory" of the human body, the main site for cellular synthesis of ATP, which is the direct energy source for cells and vital activities, providing more than 90% of the energy required for cellular activities. The healthy and efficient mitochondria can provide enough ATP for normal metabolism of the mitochondria, and can generate free radicals generated by antioxidants and normal life activities, so that the free radicals in the body can be maintained at a proper normal level, which is beneficial to the organism. However, when mitochondria are damaged, insufficient ATP production is caused, and excessive free radicals are generated to cause cell damage. If damaged mitochondria are not cleared in time, skin problems such as inflammation, pigmentation, wrinkles, etc. are induced.
The ubiquitin-proteasome system is the main pathway for about 80% of protein degradation in human body, most functional proteins need to be degraded under specific spatiotemporal conditions after exerting their effects, the misfolded proteins and the proteins in food need to be degraded by proteasome, and the degradation process of damaged mitochondria and related proteins also needs to involve ubiquitin-proteasome, which needs ATP energy supply. When the activity of proteasome is reduced due to aging of the body itself or the influence of external environment, damaged proteins and damaged mitochondria are accumulated in the body continuously, thereby inducing skin problems such as inflammation, pigmentation, wrinkles, etc., and when the accumulation is excessive, the activity of ubiquitin-proteasome is inhibited in turn, thereby forming a vicious circle.
Therefore, the mitochondria and the ubiquitin-proteasome have a relationship of mutual influence and mutual restriction, but at present, no patent/literature report for achieving the effect of protecting the skin by utilizing mutual regulation between the mitochondria and the ubiquitin-proteasome is found.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a composition with an anti-pollution injury effect, which comprises arginine/lysine polypeptide, artemia extract and hydrolyzed rice protein, has a synergistic effect on anti-pollution injury by regulating and controlling the interaction between mitochondria and ubiquitin-proteasome, can resist the injury of pollutants to skin by adding the composition into a skin care product, and has the effects of relieving skin inflammation reaction, timely removing damaged protein and mitochondria, reducing the attack of active oxygen free radicals to cells and the like, thereby having the effect of protecting the skin.
In order to achieve the purpose, the invention provides the following technical scheme: a composition having anti-contaminant damage properties comprising the following components: arginine/lysine polypeptide, artemia extract and hydrolyzed rice protein, wherein the mass ratio of the three components in the anti-pollution damage skin care product is as follows: arginine/lysine polypeptide 0.000001-0.001%; 0.00025-0.25% of artemia salina extract; 0.00005-0.05% of hydrolyzed rice protein. The above components are all calculated on dry matter.
Preferably, the three components are contained in the anti-pollution damage skin care product in a mass ratio of: arginine/lysine polypeptide 0.00001-0.0001%; 0.0025-0.025% of artemia salina extract; 0.0005-0.005% of hydrolyzed rice protein.
Among them, a known commercial product of arginine/lysine polypeptide is Hangzhou coma science and technology, Inc
Figure BDA0002953597690000021
(trade name) series raw materials with the molecular weight of 3000-5500 and the polypeptide sequence length of 20-40 amino acids are obtained by an artificial synthesis method. Researches prove that the polypeptide can specifically act on mitochondria, protect and activate the mitochondria, and improve the ATP synthesis of the organism, thereby enabling various vital activities of cells.
The artemia extract is obtained by adding artemia cysts into distilled water for rehydration, grinding, centrifuging, filtering and sterilizing to obtain an aqueous solution (see patent CN 106132396B), wherein the content of diguanosine tetraphosphate (GP4G) is 145-195mg/kg, and the aqueous solution is subjected to freeze drying to obtain the artemia extract. Artemia, a unique polar plankton, is rich in GP4G, which is a precursor of ATP and can be directly converted into ATP in cells to energize various vital activities of the cells, thus enabling the artemia to resist extreme environmental stress.
Hydrolyzed rice protein is prepared by hydrolyzing rice with papain, removing macromolecular polypeptide to obtain hydrolyzed rice protein aqueous solution (see patent CN 102439027B) containing peptides with molecular weight less than 6kDa, and having protein content of 3.5-5.5g/L, and freeze drying the aqueous solution to obtain hydrolyzed rice protein containing peptides with molecular weight less than 6kDa and rich in bioactive peptides of 3-5 amino acids including at least one aspartic acid residue, one cysteine residue and one arginine residue, and having proteasome activating effect.
After extensive literature search and experiments, the inventor of the application finds that the composition of the invention can play a role in both the acute phase and the chronic phase of inflammation caused by PM 2.5. In the acute inflammation stage, arginine/lysine polypeptide acts on mitochondria to stimulate the activity of the mitochondria, improve the synthesis of ATP of the organism per se and improve the content of endogenous ATP, and artemia extract can be directly converted into ATP to improve the content of exogenous ATP, so that the arginine/lysine polypeptide and the artemia extract can energize cells of the organism together, accelerate the metabolism of the cells, stimulate the resistance of the cells to external stimulation and reduce the expression of inflammatory factors.
In a chronic inflammation stage, inflammatory factors, free radicals and the like attack mitochondria to cause mitochondrial damage and slow or abnormal cell metabolism, at the moment, arginine/lysine polypeptide can protect and activate mitochondria in a targeted manner, and the arginine/lysine polypeptide and artemia extract together improve the ATP content and provide required ATP for ubiquitin-proteasome activation, so that the degradation and the elimination of damaged proteins (such as carbonylation proteins) are accelerated, the accumulation of the damaged proteins is reduced, and the secondary damage to cells is reduced; meanwhile, the hydrolyzed rice protein can activate ubiquitin-proteasomes, and the ubiquitin-proteasomes can assist the degradation of mitochondria for seriously damaged mitochondria to control the quality of the mitochondria, thereby relieving cell damage caused by excessive accumulation of the damaged mitochondria. The three raw materials have synergistic effect and obvious effect in the process of relieving chronic inflammation.
The anti-pollution damage composition can be added into skin care products such as facial masks, essence, emulsion, cream and the like. The skin care product containing the composition can resist the damage of pollutants to the skin, such as relieving skin inflammation reaction, timely eliminating damaged protein and mitochondria, reducing the attack of active oxygen free radicals to cells, and the like, thereby playing the role of protecting the skin.
Further, the invention provides a skin care product with anti-pollution and damage effects, which comprises the following 3 components in parts by weight: arginine/lysine polypeptide 0.000001-0.001%, artemia extract 0.00025-0.25%, hydrolyzed rice protein 0.00005-0.05%, humectant 0.1-10%, emulsifier 0.001-5%, skin conditioner 0.1-15%, emollient 0.01-30%, thickener 0.001-5%, antiseptic 0.001-2%, other skin care product auxiliary agent 0.001-5%, and water to make up 100%.

The experimental method comprises the following steps: the experiment is provided with a blank group (no treatment), a model group (50 mu g/ml PM2.5 dry powder), and a sample group (50 mu g/ml PM2.5 dry powder + 10% comparative examples 1-3/examples 1-2), wherein each group is provided with 3 parallels, HaCaT cells with good growth state are selected, the corresponding treatment is carried out according to the group, after 24h of culture, the cells are centrifuged at 3000rmp/min for 20min to remove particles and polymers. The supernatant was collected and assayed according to the manual of human carbonylated Protein (PC) ELISA kit (Shanghai Zheke organism).
2. The experimental results are as follows: as shown in fig. 4, cells were strongly carbonylated under PM2.5 treatment, and carbonylated protein increased by (118.47 ± 2.25)%, compared to the group of cells not treated with PM 2.5. In comparative examples 1 and 2 containing hydrolyzed rice protein, the degree of protein carbonylation was reduced by (39.00 ± 2.96)% and (45.16 ± 1.66)%, respectively, compared to the model group, and in comparative example 3 containing no hydrolyzed rice protein, the degree of protein carbonylation was reduced by only (16.06 ± 2.53)%, indicating that hydrolyzed rice protein plays a critical role in reducing protein carbonylation; the example 1 and the example 2 have better removal effect on the carbonylated protein, compared with the model group, the content of the carbonylated protein is respectively reduced by (56.36 +/-4.80)% and (65.52 +/-4.47)%, so that a synergistic effect is achieved, and the composition has better repair and removal effects on PM 2.5-induced protein damage, reduces the accumulation of oxidative damage and reduces chronic damage to the skin.
Human body experiment
The human body efficacy test is carried out on the specific embodiment 2, and the test is carried out in 12 months in Jinan, wherein the test time is 1 month. Data statistics are from https:// www.aqistudy.cn/historydata/.
1. Volunteer selection and request
30 healthy subjects (15 men and women) are aged 30-45 years, the working environment is outdoor, all the subjects have no history of skin or systemic diseases, the tested parts have no abnormality, and no drug or cosmetic irrelevant to the experiment is smeared during the testing period.
2. Test environment
The test site is constant in temperature and humidity, the ambient temperature is 20-22 ℃, the relative humidity is 40-60%, and the test subject should keep the organism in a stable state before testing. After the face of the subject was washed with clear water at about 35 ℃, the test was started after sitting still for 30min in the test environment.
3. Sample preparation
The test sample was example 2 and the placebo group was identical to the base material of example 2, with the difference that there was no composition of the invention. The medicine is used in the morning and evening every day, and the dosage of the medicine is 0.6-1.0 g/time each time.
4. Test items
(1) The experimental method comprises the following steps: transdermal water loss (TEWL value) detection
Self half-face control, example 2 was randomly distributed with placebo. The amount of transdermal water loss in the skin using the test area and the control area of example 2 and placebo for 14 days and 28 days, respectively, was measured using a skin water loss tester (Tewameter, TM300, Courage and Khazaka, germany), and the change rate was calculated with the pre-test base value of 0. The TEWL value may reflect the skin barrier condition, with a range of greater TEWL values leading to poorer skin barrier function.
The experimental results are as follows: as shown in fig. 5, the TEWL value of the example 2 group decreased significantly (p <0.001), about (11.07 ± 2.62)%, compared to the placebo group 28 days after the test sample was applied to the volunteers, which indicates that the composition and the skin care product thereof have significant repairing effect on the skin barrier, can resist the damage of the skin barrier caused by environmental pollution, and can be used in the repairing cosmetics.
(2) The experimental method comprises the following steps: skin color determination (Lab value)
Self half-face control, example 2 was randomly distributed with placebo. The changes in the L, a, b values of the skin in the test and control areas were measured using a Lab color difference meter (Colorreter CL400, Courage and Khazaka, Germany) 14 and 28 days after application of example 2 to placebo. Wherein the L value represents the brightness, and the larger the L value is, the more the color is biased to white; conversely, the color is biased to black; the saturation a of the color on the green-red axis, a negative value represents green, a positive value represents red, and the larger the a value is, the more red the skin color is; the saturation b of the color on the blue-yellow axis, negative values indicate blue, positive values indicate yellow, and the greater the b value, the more yellow the skin color.
The experimental results are as follows: the results are shown in fig. 6, and the L value significantly increased and the a and b values significantly decreased in 30 volunteers after 28 days using the skin care product of example 2. Compared with the placebo group, the L value is improved by (3.88 +/-0.61)%, the a value is reduced by (17.34 +/-2.71)%, and the b value is reduced by (9.52 +/-2.82)%. The skin care product in the embodiment 2 can remove oxidation garbage induced by PM2.5 in skin and improve skin brightness; reduce skin inflammation and reduce skin redness. The composition and the skin care product thereof have very good effect on resisting the skin damage caused by PM 2.5.
