In the cosmetic, the preservative is one or a combination of more than two of p-hydroxyacetophenone, 1, 2-hexanediol, phenoxyethanol and ethylhexyl glycerin.
Compared with the prior art, the invention adopts a certain proportion of the peony flower extract, the malachite extract and the tetrahydro-methylpyrimidine carboxylic acid as the soothing composition, and solves the problem of skin sensitivity from different ways.
Aiming at the inflammatory factors causing skin sensitivity, the peony flower extract and the malachite extract are cooperated to comprehensively reduce the expression of the inflammatory factors and effectively relieve the skin inflammation problem.
Malachite extract reacts against external stress and free radicals produced by the skin itself by increasing the activity of glutathione reductase, an important cellular antioxidant. Glutathione reductase is an important enzyme for eliminating H202 and a plurality of organic hydroperoxides in vivo, and reduces toxic H202 and lipid peroxides into nontoxic hydroxyl compounds by catalyzing glutathione, thereby protecting the structure and function of cell membranes from being damaged and interfered by peroxides and preventing skin from being induced to generate related inflammatory factors. On the other hand, the malachite extract contains trace elements which can perform double protection on skin cells by directly acting on cell protection and activating the regeneration of a natural defense system of the cells, so that the skin is indirectly prevented from being stimulated by the outside to generate inflammation.
Peony, as a traditional Chinese medicine with high medicinal value, contains various bioactive substances including terpenoids, flavonoids, steroids, glycosides, phenols, tannins, volatile oil and the like. The flos Paeoniae extract extracted by ultrasonic low temperature low pressure extraction technology contains higher content of penoniflorin, and can significantly reduce multiple inflammation parameters including TNF-alpha, IL-6 level and proinflammatory mediator level (MCP-1, COX-2, IFN-gamma, TNF-alpha, IL-6 and IL-17). Meanwhile, the composition has the function of inhibiting harmful bacteria of the skin to a certain extent, thereby blocking inflammatory signal transmission caused by skin microecological imbalance.
In the aspect of skin barrier damage, the tetrahydro-methyl pyrimidine carboxylic acid is a cyclic amino acid derivative generated by an extreme organism to ensure survival in an extreme environment. In aqueous systems, water complexes are formed, which protect and stabilize biomolecules by surrounding cells, enzymes, proteins and other biomolecules by forming a water shell around them. Skin epithelial cells, including extracellular matrix, are exposed to damage stressors (e.g., radiation, particulate matter, cold and heat, etc.), which tend to cause damage to the cell membrane, loss of water and release of stress mediators. The tetrahydro-methyl pyrimidine carboxylic acid protects and stabilizes cell membranes, reduces oxidative stress and damage, and simultaneously reduces intracellular inflammatory gene expression. On the other hand, the self-defense and repair mechanism is improved by increasing the fluidity of the cell membrane; and by increasing hydration, the skin barrier effect is improved. Clinical trials have shown that after 7 days of treatment with skin care products containing tetrahydro-methyl pyrimidine carboxylic acid, 1% of tetrahydro-methyl pyrimidine carboxylic acid reduces TEWL by 28% and redness of the skin by 45% due to its anti-inflammatory and reparative properties, corresponding to the therapeutic results for hydrocortisone.
In addition, the tetrahydro-methyl pyrimidine carboxylic acid has a certain effect of promoting the stability of active ingredients of the peony extract, the three ingredients are respectively from plant extraction, mineral elements and extreme biological fermentation, and compared with the combination of the three plant extracts, the ingredients are relatively simple and are not simple superposition use of similar core ingredients; the combination of the three active substances in a certain proportion can not only improve the original single value of each component, but also achieve the effects of supplementing each other and promoting each other synergistically.
In conclusion, the invention has the characteristics of effectively relieving the effect, improving the product stability and effectively reducing the sensitization risk.

Through the test results of four different cycles of comparative example 1 to example 4, it was found that as the concentration of the peony flower extract, malachite extract and the addition of the tetrahydro-methylpyrimidine carboxylic acid increases, the absolute values of the decrease in TEWL value and hemoglobin become larger, indicating that the soothing effect on the skin is enhanced as the three components in the composition increase. However, it was found that the TEWL values and the absolute reduced hemoglobin values of examples 3 to 4 were not as great as those of examples 1 to 3, indicating that the concentrations of the components have a certain threshold value for the skin effect within a certain range, and that too high or too low values may have an effect on the effect.
By comparing example 1 with comparative examples 1-4, it was found that the absolute value of the reduction in TEWL value for a single equivalent amount of ingredient was lower than for the three ingredient composition, except for comparative example 4. The composition is shown to maintain the skin barrier more effectively than the single herb flower extract, malachite extract. The barrier effect of a considerable amount of single tetrahydromethylpyrimidine carboxylic acid is better than that of the composition, but the price cost is far higher than that of the composition. Meanwhile, the absolute value of the reduction of hemoglobin of comparative examples 1 to 4 is lower than that of example 1, which shows that a considerable amount of the composition is more effective in reducing skin inflammation than the single component.
By comparing example 1 and comparative example 5, the soothing effect of the equivalent amount of the peony flower extract and the malachite extract was weaker than the composition. Comparative example 1 and comparative examples 6-7 found that the absolute value of TEWL reduction was somewhat improved over equivalent compositions when the absolute value of heme reduction was combined with one of the two components, the peony flower extract and the malachite extract, but the absolute value of heme reduction was not as high as for equivalent compositions and the cost was much higher than for equivalent compositions.
Stability test, stability tests were performed on the facial masks prepared in examples 1-4 and comparative examples 2-7 of the present invention.
Cold resistance test: taking a proper amount of the product, placing the product in a sample bottle, sealing the sample bottle, placing the sample bottle in a refrigerator at the temperature of-16 ℃, sampling every 7 days, continuously inspecting for 3 months, and observing appearance change.
Heat resistance test: and taking a proper amount of product, placing the product in a sample bottle, sealing the sample bottle, placing the sample bottle in a 50 ℃ oven, sampling and observing every 7 days, continuously inspecting for 3 months, and observing appearance change.
And (3) illumination test: and taking a proper amount of product, placing the product in a sample bottle, sealing the sample bottle, placing the sample bottle in an ultraviolet illumination box, sampling and observing every 7 days, continuously inspecting for 3 months, and observing appearance change.
The detection results show that the products prepared in examples 1-4 and comparative examples 1-7 have no change in appearance after high-temperature and low-temperature tests, which shows that the active combination of the cosmetic is reasonably selected, and the compositions with different concentrations can be in a stable state in a matrix system.
