Product Overview

A high-performance fluorescent whitening agent (Optical Brightener) based on disulfonic stilbene / distyrylbiphenyl chemistry. Emits an intense, radiant bluish-violet fluorescence under daylight that neutralizes yellowish undertones in cellulosic fibers, cotton, polyester blends, and laundry detergent formulations, delivering a dazzling whiteness index and wash-fast brightness.
