For procurement managers and R&D scientists in the chemical and consumer goods sectors, selecting the right raw materials is critical to product performance and market competitiveness. Optical Brightener CBS-X (CAS 27344-41-8) is a key ingredient for achieving superior whiteness in a variety of applications, most notably in detergents, textiles, and paper. Understanding its properties and how to source it effectively is paramount. NINGBO INNO PHARMCHEM CO.,LTD. aims to be your trusted partner in this process.

What is Optical Brightener CBS-X?

Optical Brightener CBS-X, also known as Fluorescent Brightener 351 or by its chemical name Disodium 4,4′-bis(2-sulfostyryl)biphenyl, is a type of fluorescent whitening agent (FWA). Its core function is to absorb ultraviolet light and re-emit it in the blue region of the visible spectrum. This phenomenon cancels out yellow tones and makes materials appear whiter and brighter. Its efficacy in laundry detergents, for instance, directly impacts consumer perception of cleanliness and fabric quality.
