Abstract

The invention relates to the field of cosmetics, in particular to a sunscreen lotion and a preparation method thereof. The sunscreen emulsion is prepared from the following raw material components inparts by weight: 10 to 20 parts of soybean lecithin; 5-10 parts of caprylic triglyceride, 2-5 parts of a humectant, 3-10 parts of tween-80, 0.05-0.1 part of aromatic amino acid, 0.05-0.1 part of nucleoside, 0.1-0.5 part of Chinese wolfberry, 1-5 parts of titanium dioxide, 1-3 parts of trollius chinensis extract, 1-2 parts of preservative and 30-50 parts of deionized water. According to the sunscreen lotion, aromatic amino acid, nucleoside, Chinese wolfberry polysaccharide, titanium dioxide and a tropaeolum majus extract are used as sunscreen effective components; natural compounds are used asraw materials, skin anaphylaxis can be effectively avoided, the effects of absorbing ultraviolet light and scattering the ultraviolet light can be achieved through mutual cooperation, meanwhile, formation of free radicals can be prevented, formation of melanin can be inhibited, and the effects of sun protection and repairing are achieved.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a sunscreen lotion and a preparation method thereof. Background technique [0002] Ultraviolet rays in the sun and high-energy blue light can cause adverse reactions to the skin, such as erythema, accelerate the secretion of melanin, darken the skin, cause the decomposition of skin collagen and elastin, and make the skin age. Awareness, awareness of sun protection is gradually increasing, and the requirements for sun protection cosmetics are getting higher and higher. [0003] In the prior art, anti-UV agents such as methylene bis-benzotriazolyl tetramethylbutylphenol, ethylhexyl methoxycinnamate, ethylhexyl salicylate, diphenyl Ketone-3, etc., obtained by mixing and emulsifying the general matrix milk phospholipids, moisturizers, preservatives and other raw materials of cosmetics, or using chemically synthesized anti-UV agents and inorganic anti-UV agents such as zinc oxide, titanium d...
