Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a face cream containing rose fermentation liquor and a preparation method thereof.

Background

With the continuous improvement of living standard, people have higher and higher requirements on skin care products, besides moisture retention, the product is also expected to have certain efficacy, and the relaxation and the anti-allergy are important requirements.

Metazoan (postbiotics) means: metabolites, cracked extracts, cell wall components and even culture supernatants of probiotics can show obvious probiotic effects, and the components with health efficacy are called postnatal. The postnatal has antibacterial, antioxidant, and antiinflammatory effects. Early studies found that tryptophan is produced by microbial metabolism, and that tryptophan can relieve symptoms and inflammatory reactions in atopic dermatitis patients.

The activation medium is an MRS medium and comprises 5g/L of beef extract, 10g/L of peptone, 20g/L of glucose, 4g/L of yeast powder, 5g/L of sodium acetate, 0.2g/L of magnesium sulfate, 2g/L of triammonium citrate, 2g/L of dipotassium phosphate, 0.05g/L of manganese sulfate, 801 g/L of tween-801, 20g/L of agar and the pH value of 6.2 +/-0.2.

(4) And (3) fermentation post-treatment: sterilizing the initial fermentation liquid at 121 deg.C for 15min, crushing thallus with High Pressure Homogenizer at Pressure of 100MPa for 3 times, and centrifuging to obtain the final product.

Preparation examples 2 to 12 were carried out by changing one experimental parameter, and other operation steps and test procedures were the same as those of preparation example 1, and the specific setting method is shown in table 1. The bifidobacterium adolescentis CICC 6175, the bacillus natto CICC10262, the lactobacillus bulgaricus CICC 20271 and the saccharomyces cerevisiae CICC 1252 in the preparation examples are all purchased from China center for industrial microorganism strain preservation and management.

The extraction method of the rose extract in comparative example 1 was: pulverizing dried flos Rosae Rugosae, sieving with 100 mesh sieve, adding water to obtain 10% mixed solution, sterilizing at 121 deg.C for 15min, maintaining at 40 deg.C for 48 hr, sterilizing at 121 deg.C for 15min, centrifuging, and collecting supernatant to obtain clear water extractive solution.

The preparation method of the rose fermentation liquor in the comparative example 2 comprises the following steps: replacing the activation medium in the step 2) with a Sabouraud's dextrose liquid medium.

TABLE 1

Nutrient content detection

Measuring the total flavone content of the rose fermentation liquor prepared in preparation examples 1 to 12 and the rose extract prepared in comparative examples 1 and 2 by a spectrophotometry method; determining the total sugar content by referring to GB/T5009.7-2008; the amino acid content was determined with reference to GB/T5009.124-2003. The test results are shown in tables 2 and 3.

TABLE 2 Rose fermentation broth content

TABLE 3 amino acid content of Rose fermentation broth

The above experimental results show that, as can be seen from the comparison of preparation example 1 and comparative example 1, the rose fermentation broth according to the present invention contains more active materials, such as polysaccharides, flavones and amino acids, than the conventional aqueous rose extract.

As can be seen from the comparative preparation examples 1 to 6, when Bacillus natto CICC 10262, Lactobacillus bulgaricus CICC 20271 and Saccharomyces cerevisiae CICC 1252 are used as the fermentation strains and the mass ratio of the Bacillus natto CICC 10262 to the Lactobacillus bulgaricus CICC 20271 to the Saccharomyces cerevisiae CICC 1252 satisfies 1 (2-5) to (2-5), the active substance content in the rose fermentation liquid is the highest.

As is clear from comparison of preparation examples 1 and 7 to 9, when algal polysaccharides were added to both the activation medium and the amplification medium, the active substance content could be further increased. However, replacing trehalose with glucose or rice flour does not have a corresponding effect, because the trehalose stimulates the strain to express certain genes, so that the capability of the strain to decompose and synthesize active substances is improved, and the strain is more vigorous in growth state and stronger in activity.

As is clear from comparison of preparation example 1 and comparative example 2, more active substances were obtained by using the solid activation medium than by using the liquid activation medium. And compared with liquid culture medium, the solid culture medium has lighter weight per unit volume and lower requirements on required equipment in the production process. A large amount of liquid strains need to be cultured in a large-scale liquid fermentation tank, so that the requirements on fields and energy (steam) are high; the strain is cultured by using the solid culture medium, only sterilization equipment is needed, and the strain can be produced under the condition of lower conditions.

TABLE 4

Time (h)	Example 1	Example 2	Example 3	Example 4	Comparative example 3	Comparative example 4
							0	18.57	22.59	25.75	28.23	21.86	24.57
0.5	48.52	49.87	48.23	50.34	37.41	40.59
							1	56.31	58.34	56.98	59.94	42.16	49.56

Test example 2 anti-allergy efficacy measurement

The test persons were selected to be 30 persons, male and female, 18-60 years old, and consciously a sensitive skin population (facial visibility was reddish), and were divided equally into three groups, one group of 10 persons.

A first group: the cream prepared in example 1 was used;

second group: the cream prepared in comparative example 3 was used;

third group: the cream prepared in comparative example 4 was used.

Each group visited day 0 (before using the product), day 14 (after using the product), and day 28 (after using the product), respectively, and selected the side with more severe redness, and the same side was measured using a water loss test probe Tewameter TM300, a melanin and heme test probe Mexameter MX18, and the improvement of water loss and haematochrome was observed, and the difference of percutaneous water loss on the face was analyzed as shown in FIG. 1, and the redness on the face was analyzed as shown in FIG. 2. The transdermal water loss (TEWL) is also called transdermal water loss, which means that the water in the deep dermis is evaporated and lost through the epidermis and is an important parameter for describing the skin barrier, the larger the TEWL is, the more the transdermal water loss is, the poorer the skin barrier function is, and the poorer the capability of the skin for resisting external stimulation is; the content of red pigment is related to skin inflammation, and when skin inflammation occurs, the content of red pigment is increased. As can be seen from figures 1 and 2, the addition of the rose fermentation liquor prepared by the invention can improve the anti-allergy effect of the cream, and the added rose fermentation liquor can regulate the skin as a metazoan to achieve the effects of soothing and calming the skin.

The inventors have also conducted the above experiments on other examples, and the results are substantially the same and, because of space limitations, are not listed one by one.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
