Embodiment 1
[0041] Add 100 mL of water to the dissolving tank, slowly add 5 g of L-glutamic acid, 2 g of theanine, and 0.5 g of mannose into the dissolving tank, stir to dissolve all, and mix evenly to obtain a composition solution.
[0042] The composition solution was stirred at 80° C. for 4-6 hours, condensed to a solid state with liquid nitrogen, placed in a freeze dryer (Yaxing, LGJ-10N) for 24-48 hours of freeze-drying process, until the solvent was completely removed to obtain Composition powder for inhibiting hyaluronidase activity.
Embodiment 2-6
[0044] Example 2-Example 6 is different from Example 1 in that the dosages of glutamic acid, theanine and mannose are different, and the specific parameters are shown in Table 1.
Embodiment 7
[0076] Example 7 Preparation of skin care products
[0077] A skin care product is formulated and prepared as follows:
[0078] (1) Add 0.5 g of sodium hyaluronate (molecular weight 1.5 million, batch number 1810195) into 50 mL of water, and stir until completely dissolved;
[0079] (2) adding glutamic acid, theanine, mannose, preservatives, and functional ingredients to the mixture of step (1), stirring to make them all dissolved, and adding water to make up the volume to 100 mL;
[0080] (3) Adjust pH to 6.5 with 0.1% NaOH solution to obtain a skin care product.
[0081] According to the above preparation method, the skin care products of Example 7-1 and Comparative Examples 7-1 to 7-8 were prepared according to the content of each raw material in the raw material composition comparison table in Table 4.
[0082] Wherein, in the step (3) of Comparative Examples 7-7, the pH was adjusted to 4.5 to obtain a skin care product.
[0083] In Comparative Examples 7-8, in step (3)...
