About Optical Brighteners

There are approximately 400 brightener types listed in the Colour Index, but less than 90 are actually produced commercially and only a handful are commercially important. Generically, the C.I. FBA number can be assigned to a specific molecule, however, some are duplicated, since manufacturers apply for the index number when they produce it. The global OBA production for plastics, textiles and detergents is dominated by just a few di- and tetra-sulfonated triazole-stilbenes and a di-sulfonated stilbene-biphenyl. These are subject to fading when exposed long term to UV, due to the formation of optically inactive stilbene cis-isomers found at the center of the molecule. Exposed to gases and especially oxygen they will fade too, like most dye colorants. All brighteners have extended conjugation and/or aromaticity, allowing for electron movement. Some non-stilbene brighteners are used in more permanent applications such as whitening synthetic fiber. 

2.Application of Optical Brightener FP-127 

Optical Brightener FP-127 is the chemical compound that absorb light in the ultraviolet and violet region of the electromagnetic spectrum. These additives are often used to enhance the appearance of color of plastic and fabric , causing a "whitening" effect, making materials look less yellow by increasing the overall amount of blue light reflected.

Optical Brightener FP-127 is Wide-range in application, it is especially suitable for brightening serial products of polyvinyl chloride and polystyrene, such as high temperature resistant containers, Sheet, pipe, soles, toys and so on.

Optical Brightener FP-127 can also be used in other hot plasticity plastics and coating, printing ink, synthetic fibers ,etc. for brightening and whitening. Because it’s obvious effect and strongly fluorescent appearance under UV illumination, it is have been used in many field and be highly evaluated.
