Abstract

The invention discloses a rutin sunscreen cream with high ultraviolet absorption rate and a preparation method of the rutin sunscreen cream. The rutin sunscreen cream comprises a mixed absorbent, ethanol, glycerol, propylene glycol, 10-15 parts of aloe juice, glycerol polyacrylate, a preservative, essence, a polyether modified organosilicon nonionic surfactant, menthyl salicylate and deionized water. The mixed absorbent can absorb ultraviolet rays of UVA and UVB wavebands at the same time, and has better light stability. The polyether modified organic silicon nonionic surfactant can prevent water in the rutin sunscreen cream from being directly taken away to destroy the sunscreen performance when absorbing ultraviolet rays, or prevent water in the skin from being directly taken away, so that a rutin sunscreen cream system is indirectly stabilized. The added menthyl salicylate has a cool feeling in use, so that the greasy feeling of the rutin sunscreen cream after the mixed absorbent isadded is improved. By improving the rutin sunscreen cream, the ultraviolet absorption capacity of the sunscreen cream is enhanced, and meanwhile the greasy feeling brought by oil-soluble substances is improved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a rutin sunscreen with high ultraviolet absorption rate 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 deep lay...
