Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and in particular relates to a composition containing green plum flower extract and having pore-shrinking effect and application thereof. Background Art

[0002] At present, the proportion of people with large pores is increasing, which seriously affects personal image and is also one of the skin problems that consumers are most concerned about. The main reason for large pores is vigorous oil secretion and pore blockage caused by dirt, which causes the pores to expand. The basal layer of the epidermis of the skin continuously produces cells and transports them to the upper layer. After the cells age, they generally fall off naturally. However, for those with blocked pores, the skin metabolism is not smooth and cannot fall off as expected, causing the pores to expand. In addition, loose and aging skin can also cause large pores. With the increase of age, blood circulation gradually becomes unsmooth, and the subcutaneous fat layer of the skin is prone to looseness and lack of elasticity. If it is not properly maintained and cared for, it will accelerate aging and the pores will naturally expand.

[0003] At present, the effect of shrinking pores still mainly relies on astringent ingredients such as witch hazel extract, but the astringent effect is short-lived and cannot achieve complete and lasting pore shrinkage. Summary of the invention

[0004] In view of the above existing problems, the present invention provides a composition containing green plum flower extract having the effect of shrinking pores and its application. The specific technical scheme is as follows:

[0005] The first object of the present invention is to provide a composition containing green plum flower extract and having the effect of shrinking pores, which comprises 90-99.9% of green plum flower extract and 0.1-10% of palmitoyl tripeptide-5 by mass percentage.

[0006] The present invention starts from the root cause of enlarged pores. By combining green plum flower extract with the signal peptide palmitoyl tripeptide-5, it promotes the extracellular matrix synthase and inhibits metalloproteinases, thereby regulating the protein turnover of skin tissue, increasing the synthesis of extracellular matrix such as collagen, elastin and proteoglycans, making the skin firm and fighting aging. The combination of green plum flower extract and palmitoyl tripeptide-5 has a significant synergistic effect and has an unexpected ability to shrink pores.

[0007] Furthermore, the green plum flower extract is prepared by alcohol extraction.

[0008] Furthermore, the preparation method of the green plum flower extract is as follows: extract the green plum flower with ethanol having a volume fraction of 20-40%, with a solid-liquid ratio of 1:15-25, reflux extraction at a temperature of 80-90°C for 2 times, each extraction for 1-3h, combining the 2 filtrates, and then concentrating under reduced pressure to 1.5-2.5 times the weight of the green plum flower feed amount, adding 1,3-butanediol at 3-5 times the weight of the green plum flower feed amount, adding water at 0.5-2 times the weight of the green plum flower feed amount, stirring evenly and filtering to obtain the green plum flower extract.

[0009] The second object of the present invention is to provide the use of the composition containing green plum flower extract having pore-shrinking effect in preparing pore-shrinking essence.

[0010] Furthermore, the pore-shrinking essence comprises, by mass percentage, 80-95% water, 0.1-0.5% polyacrylate cross-linked polymer-6, 0.01-0.3% xanthan gum, 1-7% glycerol, 1-7% 1,3-butylene glycol, 0.1-2% PEG / PPG-17 / 6 copolymer, 0.1-0.6% PE9010, 0.01-0.3% essence, and 0.1-3% of a composition containing green plum flower extract with the effect of shrinking pores.

[0011] Furthermore, the preparation method of the pore-shrinking essence is as follows: polyacrylate cross-linked polymer-6, xanthan gum, glycerin and 1,3-butylene glycol are evenly mixed, then water is added, the temperature is raised to 80-90°C, and after stirring evenly, the temperature begins to drop to 40-50°C, and then PEG / PPG-17 / 6 copolymer, PE9010, essence, and a composition containing green plum flower extract with the effect of shrinking pores are added in sequence, stirred evenly, and cooled to room temperature.

[0012] The beneficial effects of the present invention are:

[0013] The present invention combines the green plum flower extract and the palmitoyl tripeptide-5 in a certain proportion, so that the composition containing the green plum flower extract and having the effect of shrinking pores has a very excellent effect of shrinking pores, and the two components have a significant synergistic effect; and the main active ingredients of the present invention are extracted from pure natural plants or synthesized from natural animal and plant ingredients, which are mild, safe, non-irritating, can shrink pores for a long time, and make the skin more delicate.

[0057] Pore ​​detection:

[0058] Detection area: face (whole)

[0059] Testing equipment: CBS cloud mirror

[0060] Detection index: pore quantity detection

[0061] Testing Process

[0062] The CBS facial image analysis system was used to take photos of the subjects’ faces (frontal) and extract the number of skin pores, such as Figure 1 shown.

[0063] The subjects were tested before using the samples, 14 days and 28 days after using them, and 14 days after stopping using them;

[0064] A total of 80 people were enrolled, and the final effective number of cases was 80, with an average age of 37.67±6.39 years old. There were 8 experimental groups in total, with 10 people in each group, and the average value was taken.

[0065] The results are shown in Table 1:

[0066] Table 1 Pore detection results of various embodiments and comparative examples

[0067]

[0068] It can be seen from the above results that Examples 1, 2, 3, and 5 all have obvious pore-shrinking effects. After the trial users used it for 14 days and 28 days, the number of skin pores was significantly reduced. However, since the amount of the composition containing green plum flower extract with the effect of shrinking pores in Example 4 is small, the effect is average. And after 14 days of discontinuation, there is no obvious increase in the number, indicating that the composition containing green plum flower extract with the effect of shrinking pores of the present invention has a long-lasting pore-shrinking effect. By comparing Example 1 with Comparative Example 3, it is also shown that the effect of the pore-shrinking composition is very significant. By comparing Example 4 with Comparative Examples 1 and 2, it can be clearly seen that the combination of green plum flower extract and palmitoyl tripeptide-5 has an obvious synergistic effect, which greatly improves its pore-shrinking effect.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
