Brighten Your Way: OB


Optical brighteners are ideal whitening agents with the capacity to brighten colors and reduce yellow hues in your products. They achieve this by absorbing light in the UV spectrum and emitting it in the blue portion of the visible spectrum, thereby displaying more visible light than “absorbed” and making your products appear brighter and perceived as whiter. Our OB, 2,5-Bis[2-(5-tertbutyl-2-benzoxazoyl)] thiophene can contribute to a variety of applications from plastics and fibers to imaging and coatings and is able to be used in a variety of industries.
