note: "/" indicates no addition.
The production method comprises the following steps:
heating deionized water to 80 ℃, adding sodium hyaluronate and xanthan gum under stirring, and uniformly mixing to obtain a solution; then, the temperature is reduced to 60 ℃, and triethanolamine is added and stirred uniformly; cooling to 45 deg.C, adding Cistanchis herba fermentation liquid or Cistanchis herba extract under stirring, mixing to obtain facial mask stock solution, packaging into packaging bag containing facial mask carrier, sealing, and sterilizing to obtain the final product.
Test example 1 bacteriostatic effect of cistanche deserticola fermentation broth
The antibacterial circle method is adopted to verify that the cistanche deserticola fermentation liquor is common bacteria: inhibiting effect of Staphylococcus aureus and Escherichia coli, and taking unfermented Cistanchis herba solution as blank control;
TABLE 1 bacteriostatic effect of cistanche deserticola fermentation broth
Table 1 shows that cistanche salsa has inhibitory effects on staphylococcus aureus and escherichia coli after being fermented by lactobacillus plantarum, lactobacillus casei and lactobacillus reuteri, wherein the inhibitory effects are relatively strong after being fermented by lactobacillus plantarum. Comparative example 1, in which the fermentation time was too short, had a poor bacteriostatic effect due to a high pH. Compared with the antibacterial effect of the comparative example 2 with longer fermentation time, the antibacterial effect is not obviously improved; at this pH, most of the cells die or dissolve, and thus, the cells are likely to cause irritation or allergy to human skin.
Test example 2 stability and Effect of cosmetic containing Cistanchis herba fermentation liquid
1. Stability of the mask
To verify whether the cistanche fermentation broth has an effect on the facial mask stability, the number 4-6, 8, and 9 facial masks prepared in example 11 were placed in a biochemical constant temperature incubator at 45 ℃ for 60 days, and the facial mask stability and microbial content were examined.
TABLE 2 facial mask stability and microbial content
Table 2 shows that, even when no preservative was added, the fermented cistanche mask solution was not infected with microorganisms, and the solution stability was changed. And the mask liquid prepared from the cistanche deserticola extract can cause the situations of microbial infection and poor stability after being placed for a period of time without adding a preservative.
Skin test
220 women with rough skin, more acne marks, dark spots and the age of 20-35 years are randomly selected and divided into 11 groups of 20 people. Wherein 1-9 groups of the masks prepared according to the mask numbers 1-9 in example 11 are used respectively, 10 groups of the masks prepared by using 20% aqueous solution only containing the cistanche deserticola fermentation broth are used, and 1-10 groups of the masks are distributed three times per week; group 11 served as blank and used daily skin care products. After continuous use for 6 weeks, the skin feeling and change of the tested person are observed, tested and recorded.
TABLE 3 skin feel and Change in test person
As can be seen from table 3, in the test groups 1-6 and 8-10, the facial masks have the effects of removing acne marks and lightening spots under the condition that the facial mask liquid contains the cistanche salsa fermentation liquid or the cistanche salsa extract, and compared with the cistanche salsa extract, the effect of removing acne and lightening spots of the cistanche salsa fermentation liquid is better; in the case of the 7 th group of facial mask liquid, 80% of people do not feel obvious effect under the condition of not containing cistanche fermentation liquor; in addition, according to the results of the test groups 1, 2, 3, 4 and 10, it can be seen that sodium hyaluronate has a certain synergistic effect on the acne mark removing and stain lightening effects of the cistanche fermentation broth.
