Fluorescent whitening agents (FWAs) have been manufactured since 1950 in Japan. Now, they are used very widely in the fields of paper, textile, and detergent industries.
Discussions were given to the results of medical surveys and studies on the safety of the FWAs derived particularly from diaminostilbene disulphonate.The FWAs can be considered to be safe both in chronic and acute toxicities.
Further, possibility of the FWAs' contamination to human skin or table-wares from papers and textiles was examined.The results showed that the degrees of contamination were very small or negligible.
As a conclusion, the FWAs are practically nontoxic even if they are taken into human bodies, though they can not migrate to human skin from papers or textiles containing the FWAs.
