Abstract

The invention discloses a sunscreen emulsion for preventing ultraviolet rays and a preparation method thereof. The sunscreen emulsion is prepared from the following raw materials in parts by weight: 3-5 parts of stearic acid, 2-3 parts of octyl salicylate, 1-1.5 parts of sunscreen microcapsules, 0.2-0.5 part of fatty acid methyl ester, 4-6 parts of glycerol, 15-20 parts of deionized water, 10-15 parts of mineral oil and 2-3 parts of titanium dioxide. The sun-screening agent is subjected to microencapsulation treatment to prepare the sun-screening micro-capsule, the sun-screening agent is not in direct contact with the skin through microencapsulation treatment, then skin allergy of a user is prevented, the sun-screening agent contains a large amount of hindered amine and can continuously absorb ultraviolet rays, meanwhile, the sun-screening agent contains a large amount of conjugated pi electronic structures and can perform hydrogen migration, and therefore the sun-screening effect is improved. The electron transits from a donor orbit to an acceptor orbit, and internal charge transfer and transition occur, so that strong ultraviolet absorption is generated, and the sunscreen effect is achieved.

Description

technical field [0001] The invention relates to the technical field of sunscreen preparation, in particular to an ultraviolet prevention sunscreen emulsion and a preparation method thereof. Background technique [0002] Sun exposure is one of the important factors that make the skin age, and strong ultraviolet radiation may cause skin cancer. Studies have shown that ultraviolet rays in the UVB band (290-320nm) can pass through the stratum corneum and epidermis, causing skin erythema and DNA damage, and ultraviolet rays in the UVA band (320-400nm) can reach the dermis, which is an important factor that causes melanoma. Therefore, effective sun protection is very necessary. Sunscreens can effectively absorb or scatter ultraviolet rays in the UVB and UVA bands of sunlight, and are generally divided into two categories: physical and chemical. Physical sunscreens such as titanium dioxide and zinc oxide and other inorganic particles can reflect or scatter ultraviolet radiation, ...
