After years of animal and human experiments, it has been shown that even direct contact with fluorescent whitening agents on the skin is non irritating and does not cause skin allergies. Fluorescent whitening agents are not absorbed by the skin, and even if there may be a small amount of adhesion to the skin during use, they will not react with the human skin. Moreover, they can be easily completely washed off through daily washing activities (such as washing hands, bathing, etc.) and will not be absorbed through the skin. Therefore, direct contact between the skin and laundry detergent with added whitening agents will not cause harm.

The absorption spectrum characteristics of fluorescent whitening agents are closely related to the solvent used. The position and intensity of the fluorescence spectrum of the same fluorescent whitening agent may vary significantly in different solvents. Therefore, measuring the fluorescence intensity of fluorescent whitening agents requires a suitable solvent to transform the sample into a solution. Improper solvent selection can lead to the solution not complying with the Lambert Beer law and inaccurate measurement results. The general selection of solvents should follow the following principles:

　　Transferable fluorescent whitening agent is a color conditioner with the function of brightening and brightening, widely used in various fields such as papermaking, textiles, and detergents. There are strict standards prohibiting the addition of fluorescent whitening agents in tissues and other products.
　　Transferable fluorescent whitening agent is a fluorescent dye. Adding fluorescent whitening agent to the paper industry can improve the appearance of paper, make it white, reduce the cost of pulp bleaching, reduce energy consumption, and reduce environmental pollution. However, due to the potential harm to human health caused by the transferability of fluorescent whitening agents in paper, it is necessary to strengthen the restrictions on transferability of fluorescent whitening agents in relevant paper standards to ensure the personal health of consumers.

　　Among the numerous plastic products on the market, there are various materials available, roughly divided into three categories: hard plastic, semi soft plastic, and soft plastic. These three types of plastics are commonly used around us, and various additives are added to their products in the processing technology, especially white products, which will add whitening agents.

　　Plastic is an indispensable product in our daily life, almost every household needs it, and plastic fluorescent whitening agent is an indispensable auxiliary in the plastic production process. Many people will ask why fluorescent whitening agent is also added to plastics, and what are its benefits. Next, Xingye editor will analyze the benefits of adding fluorescent whitening agent to plastics.

　　The following elements will affect the function of fluorescent whitening agents:
　　1. Pre processing: The higher the whiteness of the original data, the better the whitening effect.
　　2. The dosage of fluorescent whitening agents, each type of fluorescent whitening agent has its specific saturation concentration limit. If it exceeds a fixed limit value, not only will the whitening effect not be added, but it will also present a "yellowing" phenomenon, making the whitening become "yellowing".
