Description

Composition for reducing skin purpurin and preparation method and application thereof

Technical Field

The invention belongs to the field of cosmetics, and particularly relates to a composition for reducing skin purpurin, and a preparation method and application thereof.

Background

The severe manifestations of purpuria mainly include acne, pimple, nodule, cyst, sunken skin, hyperplastic paralysis, etc., especially the skin damage on face brings heavy burden to the spirit and mind of the patient, which may cause the patient to have bad mental states such as anxiety, depression, etc., and affect the life, study and work of the patient. The face is usually the first thing a person notices, and purpura can negatively affect the perception of others. The skin purpura is a chronic inflammatory disease of the pilosebaceous glands with high incidence rate, and the disease can affect people of any age group. The pathogenesis of the skin purpurin is complex and is the result of multifactorial action, the excessive secretion of sebaceous glands mediated by initial hormone, the abnormal keratinization and inflammatory reaction of the opening of hair follicle sebaceous glands in the later period, the colonization of propionibacterium acnes and the delayed immune reaction are involved, and external factors and genetic factors are involved in the generation. Purpurin is a metabolite of bacteria, and if the skin contains much purpurin, pores are easily blocked, and skin problems such as skin blockage and the like are easily caused.

The most interesting item of the oil skin, purpurin, is that we often see the skin in different parts, and the observation with the skin image analysis system VISIA reveals that especially the T-region of the face (forehead and nose) emits a lot of fluorescence, which is actually the metabolite of bacteria parasitizing in the mouth of the hair follicle, also called "porphyrin". Porphyrin can present fluorescent points with different colors under the excitation of ultraviolet light, for example, brick red bright spots are related to propionibacterium, blue white fluorescence is related to malassezia folliculitis, and the extinguishment of the porphyrin points is of great significance for controlling skin inflammation and controlling oil.

CN106511153A discloses a nano composition with acne removing efficacy and a cosmetic or skin care product containing the same. The nano composition with the acne removing effect comprises the following components in percentage by weight: 0.1-5% of purslane extract, 0.5-5% of compound consisting of keratin amino acids, betaine and chicory root extract, 0.78-0.5% of quaternary ammonium salt-730.001, 1-10% of emulsifier, 5-15% of grease and the balance of water. The nano composition with the acne removing effect and the cosmetic or skin care product containing the composition can inhibit the secretion of skin sebaceous gland grease, so that the skin sebaceous gland grease is reduced, but the skin purpura is still poor in effect of radically treating the skin purpura, and is easy to repeat after long-term use.

CN110227058A discloses a pleiotrophin composition comprising: 0.01-1% of a hypoxic pretreated pleiotropic factor solution, 0.05-1% of sodium hyaluronate, 2-10% of mannitol, 0.5-2% of sodium ascorbate, 0.5-2% of panthenol, 0.05-0.2% of phenoxyethanol, and the balance of water. The pleiotropic factor composition provided by the invention can be used for nourishing and filling tissues of skin, and the subcutaneous deep tissue participates in the repair of basal cells, but the pleiotropic factor composition has poor effect on radically treating skin purpura and is easy to repeat after long-term use.

Therefore, the development of a cosmetic capable of fundamentally reducing skin purpurin is the focus of current research in the art.

Test example 1

Haemolysis test of erythrocytes

The erythrocyte hemolysis test is one of the alternatives of the rabbit eye irritation test (Draize test), and the basic principle is to evaluate the damage of chemicals to eye tissue cells by measuring the dissolution amount and denaturation degree of hemoglobin. The RBC test is used internationally for evaluating eye irritation studies on chemicals such as cosmetics and raw materials.

The purpurin-reducing compositions prepared in examples 1-5 and the purpurin-reducing compositions prepared in comparative examples 1-4 were subjected to a red blood cell hemolysis test according to the RBC test protocol and grading standards of the European Alternatives validation Process (ECVAM). ECVAM. ECVAM DB-ALM INVITOX Protoco, Red blood cells testsystem INVITOX No.37 Ispra. Italy ECVAM,1994 ]. The specific test method is shown in table 1:

TABLE 1

L/D	Grading
		﹥100	Has no irritation
10﹤L/D≤100	Micro-stimulation property
		1﹤L/D≤10	Mild irritation
0.1﹤L/D≤1	Moderate irritation
		L/D≤0.1	Severe irritation

Results of erythrolysis experiments of the purpurin-reducing compositions prepared in examples 1 to 5 and the purpurin-reducing compositions prepared in comparative examples 1 to 4 are shown in Table 2, in which HC50 is the sample concentration at which 50% of erythrocytes are hemolyzed, DI is the protein denaturation index, and L/D is the ratio of HC50 to DI.

TABLE 2

As can be seen from the results of the experiments on hemolysis of erythrocytes in Table 2, the compositions for reducing skin purpurin prepared in examples 1-5 of the present invention all had L/D values of more than 100, and the irritation was classified as non-irritating, indicating that the compositions for reducing skin purpurin prepared in the present invention all had the characteristics of being mild and non-irritating, and that the sample concentration HC of 50% of erythrocytes in the compositions for reducing skin purpurin prepared in examples 1-5 was hemolyzed₅₀HC's substantially greater than the skin purple reducing compositions prepared in comparative examples 1-4₅₀Meanwhile, the protein denaturation index DI is obviously smaller than that of the composition for reducing the skin purpurin prepared in comparative examples 1-4, which shows that the four components of the composition are scientifically and reasonably compatible, and the toxic and side effects and the irritation can be obviously reduced after the synergistic effect is achieved, so that the aims of weakening the cell hemolysis degree and reducing the protein denaturation are fulfilled.

Test example 2

In vitro oil control efficacy evaluation test

Test samples: the purpurin reducing compositions prepared in examples 1-5 and the purpurin reducing compositions prepared in comparative examples 1-4.

Subject: liver of 3 male SD rats

Experimental procedure 9 identical 5 α -reducing enzyme solutions were prepared from liver homogenates of 3 male SD rats, and divided into 9 groups, and one of the composition samples was added to each group, and the inhibition rate of the oil control composition containing the control composition on the 5 α -reducing enzyme solution was measured through a series of reaction systems, and the higher the inhibition rate is, the better the oil control effect is, and the test results are shown in Table 3.

TABLE 3

As can be seen from Table 3, the inhibition ratio of the skin purpurin reducing composition prepared in examples 1-5 to 5 α -reductase solution is generally higher than that of the composition prepared in comparative examples 1-4, and the inhibition ratio to 5 α -reductase solution is between 33.20-60.32%, wherein the inhibition ratio of example 1 is the highest and reaches 60.32%, so that the oil control effect is the best.

Test example 3

Pathogenic bacteria inhibition test

The examples and comparative examples were tested for the effect and effect on the production of a flora in the presence of both probiotics and pathogens. The skin purple-reducing compositions prepared in examples 1 to 5 and the skin purple-reducing compositions prepared in comparative examples 1 to 4 were prepared at a mass concentration of 0.5%, respectively. The colonies were then incubated in the above medium and the number of bacteria was counted after 24 hours. The flora is a mixed flora of Micrococcus keiskei and Staphylococcus aureus, and the specific test results are shown in Table 4 (wherein T24/T0 represents the bacterial growth multiple within 24 hours).

TABLE 4

As can be seen from the test data in Table 4, the skin purple reducing compositions prepared in examples 1-5 showed significantly less pathogenic bacteria after 24 hours of incubation than the compositions of comparative examples 1-4. This indicates that the skin purple reducing composition of the present invention can significantly reduce the number of pathogenic bacteria due to lack of food and nutrition, and has the effects of selectively being utilized by probiotics and inhibiting the pathogenic bacteria, thereby fundamentally inhibiting the metabolism of bacteria producing skin purple. Moreover, compared with comparative examples 1 to 4, the skin purple reducing compositions prepared in examples 1 to 5 have a larger reduction amount of pathogenic bacteria, which shows that the skin purple reducing compositions provided by the invention can effectively inhibit the breeding and metabolism of pathogenic bacteria through reasonable collocation and synergy of the four active ingredients.

Test example 4

Purple testing of skin image analysis System VISIA

90 subjects were selected and divided into 9 groups of 10 subjects, and the compositions for reducing skin purple prepared in examples 1 to 5 and the compositions for reducing skin purple prepared in comparative examples 1 to 4 were tried for 2 weeks, respectively, and before trial, after trial for 1 week and after trial for 2 weeks, photographs were taken using the skin image analysis system VISIA, purple characteristic counts were recorded, and the average value was calculated, and the specific test results were as described in table 5:

TABLE 5

As can be seen from the test data in Table 5, the number of purple characteristic of human face was significantly reduced in subjects after 1-2 weeks using the skin purple reducing compositions prepared in examples 1-5, and the number of purple characteristic was reduced to 11 or less after 2 weeks of trial. Compared with the compositions prepared by using comparative examples 1-4, the composition for reducing the skin purpurin has the advantages that the number of the facial purpurin characteristics of human faces is obviously reduced, the effect is stable, and the repeated phenomenon cannot occur after long-time use, so that the composition for reducing the skin purpurin has the synergistic effect by reasonably matching the four active ingredients, and can effectively reduce the skin purpurin.

In addition, fig. 1 is a diagram showing the characteristics of the purple pigment of the face before trial use of the subject. Fig. 2 is a facial purple profile of a subject 1 week after using the skin purple reducing composition prepared in example 1. Fig. 3 is a facial purple profile of a subject 2 weeks after using the skin purple reducing composition prepared in example 1. It can also be clearly seen that the number of human facial purpurin features is greatly reduced after the composition for reducing skin purpurin is used, and the effect is basically the same between 1 week and 2 weeks of the test, so that the problem of purpurin is completely cured without repeated appearance.
