Cellulose fibers, encompassing materials like cotton, linen, and rayon, are fundamental to numerous industries, particularly textiles and paper. A common challenge in processing these fibers is achieving and maintaining a high degree of whiteness, which naturally degrades over time or through processing. Fluorescent Whitening Agent 113 (FWA 113), also known as Optical Brightener BA, offers a powerful solution to this challenge, ensuring optimal brightness and a non-yellowing finish. NINGBO INNO PHARMCHEM CO.,LTD. is a dedicated supplier of this advanced cellulose fiber whitening agent.


FWA 113 distinguishes itself through its unique mechanism: it absorbs invisible ultraviolet light and re-emits it as visible blue light. This compensates for the inherent yellowish hue of cellulose fibers, making them appear significantly whiter and brighter to the human eye. This optical effect is crucial for meeting modern aesthetic standards in textiles and paper. Our Optical Brightener BA exhibits exceptional fluorescent brightener pH stability, performing robustly across a wide range, specifically pH 4.5-11. This broad tolerance is vital for cellulose processing, as different stages may involve varying pH conditions, ensuring consistent whitening performance without degradation of the agent.


The superior performance of FWA 113 is particularly evident when compared to other brighteners like VBL, especially in acidic environments (pH 4.5-7), where it shows a significantly better whitening effect. This efficiency also translates into economic benefits, as its high potency allows for a 15-25% reduction in conventional dosage, lowering material costs for manufacturers. For those looking for optical brightener for cellulose price options, NINGBO INNO PHARMCHEM CO.,LTD. provides competitive pricing and bulk supply options, making it cost-effective to integrate this high-performance agent into your production lines.


Beyond its technical merits, FWA 113 ensures that the whiteness achieved is durable and resistant to yellowing, a common issue with natural fibers. Its stable quality, high purity (≥99%), good weatherability, and migration resistance mean that the brightening effect is long-lasting and uniform, enhancing the overall quality and lifespan of the treated cellulose products. Whether you are processing raw cellulose pulp, sizing paper, or finishing cotton and linen fabrics, this agent guarantees a premium outcome.
