Problems solved by technology

UVA is the most carcinogenic, and its sunburn and sunburn effects are 1000 times that of UVB. Although it acts slowly on the skin, it accumulates over time and is one of the causes of serious damage to skin aging.

preparation example Construction

[0045] The second aspect of the present invention provides a kind of preparation method of the natural plant enzyme enzyme sunscreen that improves cell activity, comprises the following steps:

[0046] (1) Use kudzu root for enzyme fermentation: crush kudzu root with a weight fraction of 40 parts through a 100-mesh sieve, beat the kudzu root powder and water at a mass ratio of 1:15, then filter with gauze, remove the filter residue, centrifuge and take the supernatant for cooking Pueraria root juice was obtained in 2 hours, yeast was inserted into the pueraria root juice, and fermentation was carried out at a temperature of 30° C. for 60 hours to obtain the Pueraria root plant enzyme. ;

[0047] (2) Take 5-10 parts of cerium nitrate solution, drop the precipitating agent sodium hydroxide into the solution at a uniform speed, and after the solution pH=12, add H 2 o 2 , and at the same time continue to drop sodium hydroxide solution. After the precipitation is complete, stir a...

Abstract

The invention discloses a natural plant enzyme sunscreen cream capable of improving the cell viability and a preparation method thereof. The natural plant enzyme sunscreen cream is prepared from plantenzymes, lattice-modified nano cerium oxide, self-made polyurethane, self-made chitosan, a 15-emulsifier, glycerin and preservative deionized water. According to the natural plant enzyme sunscreen cream and the preparation method thereof, nano cerium dioxide is dispersed into self-made polyurethane resin, a protective film with the adhesion performance can be formed on the surface layer of skin,the protective film adheres to the nano cerium dioxide, the cell viability and ultraviolet absorption are better improved, and positive tetravalent cerium enters cells through the protective film to act; the lattice-modified nano cerium dioxide has higher stability, the condition for forming the protective film through graft copolymerization of the polyurethane and the self-made chitosan is not limited to a wet environment any more, and the formed protective film also has the ultraviolet absorption capacity; and by improving the natural plant enzyme sunscreen cream, the ultraviolet absorptioneffect is enhanced, and the cell viability is improved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a natural plant enzyme sunscreen for improving cell activity and a preparation method thereof. Background technique [0002] The medium-wave ultraviolet component in sunlight is the key cause of skin tumors. Short-wave ultraviolet rays cannot pass through the atmosphere to reach the ground. Long-wave ultraviolet rays are related to skin aging because the main action site is in the dermis. Medium-wave ultraviolet rays mainly target cells in the epidermis. And become the main factor of skin tumors, can significantly increase oxygen free radicals in tissues, causing a series of oxidative damage, and can also cause abnormal immune system and cell apoptosis, cause skin cell DNA damage, induce DNA mutation, and even lead to skin cancer happened. Sunlight damage to human skin mainly comes from ultraviolet A (UVA) and ultraviolet B (UVB). UVA belongs to the long wave, acts on the dee...
