Fluorescent Brightener 393 absorb high energy radiation in the ultraviolet to violet region (330nm-380nm) on the part of characteristic molecules and emit lower energy radiation in blue region in visible spectrum (400nm-450nm), which yields the counteracting the yellowing appearance. FWA should be transparent on the substrate and should not absorb the visible region of the spectrum. Many FWAs contain the structure of stilbene. Stilbene is an unsaturated hydrocarbon with the formula C6H5CH=CHC6H5. Other nucleus of FWAs are coumarin, imidazole, 1,3-diphenyl-2-pyrazolin, naphtalimid, benzoxazole and heteroaromatics. FWAs are used in thermoplastics, detergents, plastic films, fibers, papers, adhesives and leathers to enhance the appearance.2,2-(4,4-Diphenol vinyl) dibenzoxazol is a Fluorescent Whitening Agent specially suitable for shaping various kinds of plastics and their products under high temperature. It has an extra ideal whitening effect on polyester fibers as well as polyester fiber containing fabrics including polyester-cotton blend fabric. This whitening agent is equivalent to Eastobrite OB-1 made in Eastman USA.
