In the competitive textile industry, achieving unparalleled whiteness is crucial for product appeal and market success. Manufacturers constantly seek advanced solutions to enhance the brightness and visual quality of their fabrics. NINGBO INNO PHARMCHEM CO.,LTD. presents Sylic® OBA 4BK, a cutting-edge fluorescent whitening agent for cellulosic fibers and synthetic blends, specifically engineered to meet these demanding requirements.


Sylic® OBA 4BK stands out due to its exceptional properties. As an anionic stilbene derivative, it efficiently converts UV light into visible blue light, effectively masking yellowish undertones and creating a radiant 'whiter-than-white' effect. This is particularly vital for garments and home textiles where pristine white is a key aesthetic. Our customers, who buy fluorescent whitening agent for cotton and other fabrics, consistently report superior results, highlighting the product’s ability to deliver a brilliant white maximum.


One of the significant advantages for textile manufacturers is the remarkable washfastness of Sylic® OBA 4BK. This ensures that the intense whiteness and brightness are maintained even after repeated washing cycles, adding to the longevity and value of the finished product. Furthermore, its high bath exhaustion means more of the product is utilized during the process, leading to greater efficiency and cost-effectiveness for a textile optical brightener manufacturer. Its good solubility in water and stability to common chemicals like alkalis and peroxide make it versatile for various processing methods, including exhaust and continuous systems.


NINGBO INNO PHARMCHEM CO.,LTD. understands the importance of reliable supply and consistent quality.
