In the competitive pulp and paper industry, the visual quality of the final product—its brightness and whiteness—is a critical differentiator. Optical Brightener BA is an essential chemical additive that profoundly impacts these optical properties, transforming raw pulp into visually appealing paper. NINGBO INNO PHARMCHEM CO.,LTD. is a distinguished pulp and paper chemical additives buy source, providing high-performance solutions for paper manufacturers worldwide.


Optical Brightener BA, sometimes referred to by its common synonym Ray-Bright Di-sulpho powder, works by a unique optical mechanism. It absorbs invisible ultraviolet light and re-emits it as blue light, effectively counteracting the natural yellowish tint of cellulose fibers. This process results in a significantly brighter and whiter paper, enhancing readability for printing paper and improving the clean appearance of packaging and tissue products. NINGBO INNO PHARMCHEM CO.,LTD. offers a premium product, ensuring superior optical effects for all paper grades.


The application of Optical Brightener BA is versatile within the paper manufacturing process. It can be effectively added during the wet end stage of pulp preparation, integrated into surface sizing solutions, or incorporated into coating formulations. Its ready solubility in water and compatibility with various paper additives make it easy to implement, ensuring efficient and consistent brightening across production lines. The precise Ray-Bright Di-sulpho powder application can significantly optimize paper brightness and visual appeal, a capability perfected by the offerings from NINGBO INNO PHARMCHEM CO.,LTD.


Beyond its primary function of enhancing whiteness, Optical Brightener BA contributes to the overall perceived quality of paper, influencing consumer preference and brand perception. Its high fluorescent strength means that a small amount goes a long way, making it a cost-effective solution for large-scale production. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing paper manufacturers with advanced chemical additives like Optical Brightener BA, enabling them to achieve superior product aesthetics and maintain a competitive edge in the global market.
