The pursuit of exceptional paper whiteness and brightness is a constant challenge in the paper manufacturing industry. This is where the scientific innovation behind Optical Brightening Agent 220 (CAS 16470-24-9) comes into play. As a leading chemical provider, NINGBO INNO PHARMCHEM CO.,LTD. understands the intricate details that drive product performance and is pleased to share insights into the science behind this critical paper chemical.

Optical Brightener 220 functions as a fluorescent dye, a class of compounds that absorb light at one wavelength and emit it at a longer wavelength. Specifically, OBA 220 absorbs invisible ultraviolet (UV) light in the range of approximately 340-380 nm and re-emits this energy as visible blue-violet light, typically around 420-450 nm. This emitted blue light effectively cancels out the natural yellow undertones present in most paper pulps. By adding this blue light, the overall reflectance of the paper increases, leading to a perceived enhancement in whiteness and brightness. This makes it a highly sought-after ingredient for paper manufacturers looking to buy chemicals that deliver tangible aesthetic improvements.

The technical advantages of Optical Brightening Agent 220 are rooted in its chemical structure and properties, making it ideal for industrial applications. Its excellent water solubility is a significant asset. This means the OBA can be easily incorporated into aqueous systems common in papermaking, whether it's added directly to the pulp slurry, the sizing press solution, or the coating formulation. This solubility ensures even distribution, preventing localized concentrations and ensuring a uniform whitening effect across the entire paper surface. For bulk purchasers, this ease of integration simplifies process design and reduces potential application issues.

Furthermore, OBA 220 demonstrates good stability, an essential characteristic for a chemical auxiliary used in demanding industrial environments. It exhibits resistance to peroxide and hypochlorite bleaches, which are commonly used in pulp processing. Its stability in alkaline conditions and in the presence of hard water ions (Ca2+ and Mg2+) means that its whitening performance remains consistent, even in varied water qualities or chemical treatment regimes. This reliability is a key reason why paper mills choose to buy this specific OBA for their formulations.
