Sylic® Fluorescent Whitening Agent OBA BBU Powder for Textile and Paper Brightening

NINGBO INNO PHARMCHEM CO.,LTD. is proud to present Sylic® Fluorescent Whitening Agent OBA BBU, a high-quality chemical auxiliary designed to deliver exceptional whiteness and brightness to a variety of substrates. As a leading supplier in the industry, we understand the critical need for effective and reliable whitening solutions that meet both performance and environmental standards.


OBA BBU is a premium-grade fluorescent whitening agent supplied in a convenient powder form. It belongs to the optical brightening agents family and is specifically formulated as a tetrasulfonic acid type Styrylbenzene derivative. This chemical structure contributes significantly to its effectiveness and versatility across numerous applications.


Primary applications for Sylic® OBA BBU include the whitening of various textile fibers such as Cotton, Chinlon, viscose, T/C, T/R, linen, Wool, and Silk. Its ability to dissolve readily in warm water and its remarkable resistance to both acid and alkali make it highly suitable for textile processing, including the popular one-bath dyeing method. The product demonstrates good compatibility with most chemical agents commonly used in dyeing and finishing processes, simplifying application procedures for manufacturers.


Beyond textiles, Sylic® OBA BBU is also highly effective in paper applications. It can be used in surface sizing, coating formulations, and directly for pulp whitening. When used for pulp whitening, it is recommended to apply BBU before the addition of alum or other cationic auxiliaries to optimize performance. For surface sizing, OBA BBU can be successfully combined with CMC, PVA, starch, and various anionic or cationic synthetic sizing agents. In coating applications, the powder should be dissolved in water prior to incorporation into the coating preparation process.


Technical characteristics of Sylic® OBA BBU highlight its superior properties. It exhibits excellent solubility, typically achieving 100 g/l dissolution at 60ºC. Its shade is characterized by a desirable blue-purple light, which helps to counteract yellowing and enhance perceived whiteness. The product maintains stability in the presence of reductants but is unstable with chlorate. It performs optimally within a pH scope of 6-11, offering flexibility in processing environments. With a recommended storage period of 24 months when stored correctly, OBA BBU is a reliable component for long-term inventory management.


One significant advantage of OBA BBU, particularly the granular type, is its performance compared to older generation optical brighteners like VBL. OBA BBU offers improved solubility, superior light fastness, and enhanced stability under acid-alkali conditions. Crucially, it delivers better whiteness at the same dosage level, allowing for more efficient use and cost-effectiveness.


While highly effective, proper application guidelines should be followed to achieve the best results. It is important to avoid using cationic additives that may cause precipitation due to conflict with this anionic fluorescent whitening agent. Additionally, water containing metal ions such as Cu, Fe, Mn, or Zn can negatively impact the whitening effect. Using a metal ion chelating agent beforehand can mitigate this issue. Direct exposure to sunlight after dissolution should also be avoided. As BBU is a highly potent fluorescent dye, using an appropriate amount is key; excessive dosage can lead to an 'extinction phenomenon' where whiteness is paradoxically reduced.


The quality and safety of Sylic® OBA BBU are paramount. NINGBO INNO PHARMCHEM CO.,LTD. ensures that this product meets rigorous international environmental certification standards. It has successfully passed certifications such as OEKO-TEX® Standard 100 and REACH, confirming that it does not contain harmful substances like APEO and formaldehyde. This makes it suitable for export and use in textile production regions with strict environmental protection requirements, including the EU and North America. Our production processes are also aligned with quality management systems like ISO9001.


Packaging for Sylic® OBA BBU is typically in 25KG carton boxes, though customized packaging options may be available upon request. Proper storage in a closed container at 20ºC ensures its stability for the recommended shelf life.
