Fluorescent agent detection, here is a simple and low-cost method, which can be irradiated with a small ultraviolet flashlight (or ultraviolet money detector). If it emits blue fluorescence (much brighter than the original color, just take more photos and compare them with other items), it means that it contains fluorescent agent. This flashlight is sold on TB. Search (fluorescent agent detection) is not expensive, generally around 10-30 yuan, which is quite practical. No matter what contains fluorescent agent, it can emit light. Pay attention to testing in the future, especially for babies, or personal products and skin care products. If it is a three-no product, there is indeed a risk of containing fluorescent agent.
In daily life, there are many opportunities to contact fluorescent agents. As long as it does not exceed a certain standard (the above method can only detect whether it contains fluorescent agent, but not whether it exceeds the standard), it will bring many benefits to our lives. If you come into excessive contact with it, it will do harm to the human body.
Tip: ultraviolet rays are invisible without illuminating fluorescent substances (if there is a small amount of white light, it is part of the visible light emitted by lamp beads, not ultraviolet rays). Ultraviolet rays are harmful to human body, so avoid direct contact with human body and long-term use.
If you don't understand, you can continue to ask and hope to adopt it. Thank you.
