Embodiment Construction

[0031] A detection method for sunscreen efficacy of sunscreen skin care products, the specific experimental method is:

[0032] (1) Before the experiment (approximately 22:00 every night), a pair of male and female zebrafish (wild-type AB line) was selected in the mating box, and the male and female zebrafish were separated with a partition, and placed in the night (dark) state for 10 hours.

[0033] (2) The next morning (around 8:00) remove the partition, and the zebrafish mate and lay eggs.

[0034] (3) Fish out the zebrafish and collect zebrafish eggs.

[0035] (4) Take the time of pulling out the partition as 0hpf, and start the experiment at 72hpf.

[0036] (5) The experimental solution was prepared, the aquaculture water group without ultraviolet irradiation was -UV, and the aquaculture water group was +UV after ultraviolet irradiation.

[0037] (6) Load the zebrafish on a glass plate, and wash it 2 to 3 times with cultured water (or PBS). Each zebrafish was numbered ...

Abstract

The invention relates to the technical field of detection, and specifically relates to a detection method for the sunscreen efficacy of sunscreen skin care products. The detection method takes zebrafish as an experimental carrier, and evaluates the sunscreen efficacy of sunscreen skin care products by comparing the completeness of zebrafish fins before and after ultraviolet radiation. The detection method is short in experiment period and low in cost, and can scientifically and effectively evaluate the sunscreen efficacy of the sunscreen skin care products.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method for detecting the sunscreen efficacy of sunscreen skin care products. Background technique [0002] With the continuous improvement of people's material living standards and the improvement of life concepts, the skin will be exposed to ultraviolet radiation for a long time when going out for work, travel, shopping and other activities. In order to prevent the skin from being tanned and sunburned, some methods are adopted to block or absorb ultraviolet rays. General sun protection methods: apply sun protection products, use sun protection clothing and other items, eat sun protection food, etc. Because it is simple and convenient to apply sunscreen skin care products, more and more people will apply sunscreen skin care products when they go out. [0003] The efficacy of sunscreen skin care products mainly depends on the SPF and PA value of sunscreen skin care products....
