Abstract

The invention relates to a method for evaluating efficacy of a sunscreen product. The method comprises the following steps: obtaining a culture solution, adding the to-be-tested sunscreen product withan active ingredient of alligator oil and a biological surfactant into the culture solution to obtain a sample solution; culturing zebrafish juveniles in the sample solution for culture time of T, and during the time of T, exposing the zebrafish juveniles to ultraviolet radiation; transferring the zebrafish juveniles exposed to the ultraviolet radiation to the culture solution for culture, and recording the degree of damage of pelvic fins, caudal fins, and dorsal fins of the zebrafish juveniles. According to the method for evaluating the efficacy of the sunscreen product, zebrafish is used asa model organism to evaluate the efficacy of the sunscreen product with the active ingredient of the alligator oil, and damage to the human health caused by the ultraviolet radiation dose of testingmethods separated from biological organisms and human bodies can be avoided.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a method for evaluating the efficacy of sunscreen cosmetics. Background technique [0002] With the improvement of people's material living standards and changes in life concepts, people's travel and leisure activities increase, so that the skin is exposed to ultraviolet rays for an increasing time, and the destruction of the ozone layer in the atmosphere is intensified, and more and more ultraviolet rays are radiated to human skin. . Therefore, the best-selling sunscreen cosmetics on the market, the active ingredients in sunscreen cosmetics are sunscreen agents, including physical blocking agents and chemical absorbers. Physical sunscreens are usually opaque substances that reflect and scatter all ultraviolet and visible light, while chemical absorbers act to selectively absorb ultraviolet light. Cosmetics added with sunscreens are applied on the skin to form a protective film, which ...
