Description

Fermentation product cosmetic for whitening, removing freckles and resisting saccharification

Technical Field

The invention relates to the technical field of cosmetic formulas, in particular to a plant fermentation composition for whitening, removing freckles and resisting saccharification and an application thereof in a fermentation product cosmetic for whitening, removing freckles and resisting saccharification.

Background

The color of human skin can therefore take on different shades, not depending on the number of melanocytes, but on the amount of various melanosomes produced, depending on the number, size, distribution and degree of melanosomes. The formation and deposition of normal melanin in melanocytes not only has the functions of protecting skin, resisting ultraviolet radiation, preventing internal tissues from overheating, and the like, but also has important significance on the health and beauty of skin. When abnormal changes such as hyperpigmentation, hypopigmentation or hypopigmentation occur in the skin, different types of dyschromatosis skin diseases such as vitiligo, albinism, chloasma, etc. are caused, and a corresponding unpleasant psychological sensation is produced.

Senescence-associated glycation is in fact a abbreviation, known collectively as non-enzymatic glycosylation, and in brief, the glycation reaction is the binding of sugars to proteins in the absence of enzymatic action, causing the proteins to lose normal structure and color, become brittle, and yellow. The protein may be of various types, including hemoglobin, elastin, collagen, and the like. The dermis layer of the skin contains a lot of collagen, so the skin is tight and elastic. After the reaction between sugars (glucose and fructose) and collagen, reversible primary glycosylation products are formed, followed by the formation of irreversible advanced glycosylation end products (AGEs). After glycation of collagen, in addition to further aging of the skin, the skin also looks yellow and therefore loses its fair texture. Not only does glycation occur in the dermis, new studies have found that proteins in the epidermis (particularly keratin) can also be glycated. In addition, AGEs can stimulate AGEs receptors and promote the production of melanin.

The whitening product in the prior art is usually only researched for inhibiting the activity of tyrosinase, and the invention aims to provide a plant fermentation composition for whitening, removing freckles and resisting saccharification and an application thereof in cosmetics.

Disclosure of Invention

In view of the above problems, the present invention aims to provide a plant fermentation composition for whitening, removing spots and resisting saccharification, and its application in cosmetics. The pure plant culture medium is safe and reliable, and is matched with probiotic fermentation, so that the inhibitory activity of the neuraminidase can be improved unexpectedly, and a good anti-saccharification effect and an anti-oxidation effect can be obtained, so that the effects of whitening, removing freckles and resisting aging are achieved.

Lactobacillus, lactic acid bacteria, are well-established probiotics and their fermentation products (usually lysates) have a certain cosmetic effect. It is known to those skilled in the art that the metabolism of probiotics is regulated in many ways, and the metabolites include many bioactive substances, such as small peptides, exopolysaccharides, saponins, amino acids, minerals, phenols, etc. The specific structure of exopolysaccharide greatly influences the physiological activity. In contrast, the team of the invention carries out a great amount of screening on the strains and improvement on the culture process so as to obtain the fermentation process with outstanding beauty effect.

Chinese patent 2013100043553 discloses a strain of Lactobacillus crispatus, which is a strain of Lactobacillus crispatus, characterized in that the preservation number of the strain is CGMCC No. 6364. The known function of the strain is to effectively realize antagonism to various pathogenic bacteria, and in addition, the strain has higher adhesion capability to vaginal epithelial cells and higher lactic acid production capability. The group of the invention finds that the lactobacillus strain has great potential as a strain of lactobacillus which is not commonly used in cosmetics, and the active extract of the conventional fermentation product has good antioxidant effect and certain activity of inhibiting the tyrosinase. The plant fermentation product is characterized by plasticity, and the fermentation process is tried to be changed, so that the addition of some plant components can obviously improve various cosmetic effects, including anti-saccharification performance, whitening performance and the like. While we observed that other strains of Lactobacillus crispatus did not have such outstanding plasticity properties.

Curcumin is a chemical component extracted from the rhizome of some plants in the families of Zingiberaceae and Araceae, wherein the Curcuma rhizome contains about 3-6% of pigment with diketone, which is a rare pigment with diketone in the plant world. Curcumin is orange yellow crystal powder, slightly bitter in taste and insoluble in water, and is mainly used for coloring products such as sausage products, cans, sauced and marinated products and the like in food production. The medical research shows that curcumin has the effects of reducing blood fat, resisting tumor, resisting inflammation, benefiting gallbladder, resisting oxidation and the like. The team of the invention tries to add a certain amount of curcumin into the culture medium, and finds that the performance of the fermentation product can be greatly changed.

The cortex mori radicis a traditional Chinese medicinal material, is root bark of mulberry, contains a large amount of nutrient substances, can promote metabolism of a body, and has a repairing effect on cells, so that the cortex mori radicis has a certain removing effect on scars, can enable the skin to become finer and smoother, and has good beautifying effect. The invention adds the cortex mori aqueous extract into the culture medium, and finds that the cortex mori aqueous extract and the curcumin can synergistically improve the beauty effect of the lactobacillus crispatus CGMCC No.6364 fermentation product. In addition, the cortex mori radicis also has certain beautifying effect and has double functions of regulating and controlling the growth of microorganisms and directly acting on the skin for beautifying.

And (3) evaluating the hydroxyl radical scavenging capacity of the plant fermentation composition for whitening, removing freckles and resisting saccharification.

Antioxidation refers to the abbreviation of antioxidant free radical, Anti-Oxidant. The human body continuously generates free radicals in the human body due to continuous contact with the outside, including respiration (oxidation reaction), external pollution, radiation irradiation and other factors. Scientific studies have shown that cancer, aging or other diseases are mostly associated with the production of excess free radicals. Research on antioxidation can effectively overcome the harm caused by the antioxidation, so the antioxidation is listed as one of the main research and development directions by health-care products and cosmetic enterprises, and is also one of the most important functional requirements of the market. Antioxidant effects are well recognized as indicative of anti-aging effects.

Inhibition of non-enzymatic glycosylation assays

The test simulates the non-enzymatic glycosylation reaction in human body by mixing and incubating bovine serum albumin and fructose, the inhibitor of the non-enzymatic glycosylation reaction is added to inhibit the reaction, the fluorescence intensity of the system with the added inhibitor is weaker than that of the control without the added inhibitor, and the inhibition rate is used for reflecting the inhibition condition of the sample on the non-enzymatic glycosylation reaction. A certain amount of a mixed solution containing 10mg/mL bovine serum albumin and 0.25mol/L fructose was taken as a reaction solution. PBS (1% by mass) solution of example 1 and comparative examples 1-4 was prepared as a treatment group, and a positive control group (1.00% by mass of Vc ethyl ether), a negative control group (PBS instead of sample) and a blank group (PBS instead of reaction solution) were set, each group having 3 parallel tubes. Incubate at 37 ℃ in the dark. The Fluorescence intensity (RFU) of each test group was measured at 370nm (absorption wavelength)/440 nm (excitation wavelength) using a Fluorescence microplate reader selected from items 1, 3, 5 and 7d, and the inhibition ratio was calculated. The results are shown in Table 3.

Comparative example 4 group (%)	5.3±0.63	6.4±0.9	7.3±1.1	9.3±2.3

As can be seen from Table 4, the inhibition rate of the non-enzymatic glycosylation reaction was gradually increased by the respective experimental groups with the increase of the incubation time.

Example 1 compared with the positive test group, the inhibition rate of the non-enzymatic glycosylation reaction is higher; the lactobacillus crispatus CGMCC No.6364 is contained, but the inhibition rate of the culture solution containing curcumin or cortex mori radicis extract fermentation is better than that of the simple lactobacillus crispatus CGMCC No.6364 fermentation culture (the inhibition rates of the comparative example 2 group and the comparative example 3 group are higher than that of the comparative example 1); and the lactobacillus crispatus CGMCC No.6364 is replaced by the lactobacillus crispatus CGMCC 1.2743 for fermentation (other culture conditions are not changed), and the inhibition rate is lowest. The active extract of the conventional fermentation product of lactobacillus crispatus CGMCC No.6364 has better inhibition rate of non-enzymatic glycosylation, and has good synergistic effect by adding curcumin or cortex mori extract, so that the inhibition rate of non-enzymatic glycosylation can be improved. Other strains of Lactobacillus crispatus did not have such outstanding efficacy.

Tyrosinase inhibition (I) was calculated for each experimental group, I ═ 100% of [1- (Ad-Ac)/(Ab-Aa) ]. The test results are shown in table 4.

TABLE 5 tyrosinase inhibition at different concentrations in each experimental group

As can be seen from the above table, the tyrosinase inhibition rate of each experimental group gradually increased with the increase of the concentration.

Example 1 had a higher tyrosinase inhibition rate compared to the positive test group; the lactobacillus crispatus CGMCC No.6364 is contained, but the inhibition rate of the culture solution containing curcumin or cortex mori radicis extract fermentation is better than that of the simple lactobacillus crispatus CGMCC No.6364 fermentation culture (the inhibition rates of the comparative example 2 group and the comparative example 3 group are higher than that of the comparative example 1); the lactobacillus crispatus CGMCC No.6364 is replaced by the lactobacillus crispatus CGMCC 1.2743 for fermentation (other culture conditions are not changed), the inhibition rate is lowest and even worse than that of the single lactobacillus crispatus CGMCC No.6364 for fermentation, which shows that the active extract of the conventional fermentation product of the lactobacillus crispatus CGMCC No.6364 has better tyrosinase inhibition rate, and the added curcumin or the mulberry bark extract has good synergistic effect, so that the tyrosinase can be greatly inhibited. Other strains of Lactobacillus crispatus did not have such outstanding efficacy.
