The product density is 1.662 g/cm³ and it is packaged in 25 kg HDPE bags with an internal liner or 500 kg jumbo bags with an internal liner.
The grade is formulated for use as an intermediate in the manufacture of fluorescent whitening agents and optical brighteners for detergents, textile processing and paper coating. In the chemical industry this purity level meets the typical specification for high‑performance optical brightening formulations. The powder’s fine particle size ensures good solubility in aqueous systems, although exact solubility data is not disclosed. Typical storage conditions are 15‑30 °C and the material is stable under normal warehouse humidity.
Importers usually request certificates of analysis and safety data sheets to confirm the 95 % purity and absence of heavy‑metal contaminants. Natraj Chemicals reports a response rate of 0 % and does not list a minimum order quantity, so buyers should negotiate MOQ directly. Trade terms can include FOB or CIF, and payment is often arranged via T/T after document verification. The bulk packaging facilitates container loading for large‑scale production lines.
