1. Product Description
Achieve Exceptional Whiteness with Optical Brightener BBU – The Premium Stilbene-Based Whitening Agent for Textiles and Paper.
Optical Brightener BBU, internationally designated as Fluorescent Brightener 220 (C.I. 220), is a high-performance distyrylbiphenyl derivative that represents the industry standard for whitening cellulose fibers and paper products . This sophisticated disulfonic compound features a unique stilbene-based molecular architecture with multiple water-soluble groups, delivering exceptional whitening efficacy combined with outstanding application versatility .
The advanced molecular structure of BBU enables superior photophysical performance: it absorbs invisible ultraviolet radiation in the 348-350 nm range and re-emits it as brilliant blue-violet visible light, effectively neutralizing the natural yellowish cast inherent in cellulose fibers and paper pulp . With its anionic character and excellent substantivity to cellulosic substrates, BBU delivers a clean, "whiter-than-white" appearance that enhances the perceived quality of finished products.
What truly distinguishes Optical Brightener BBU from conventional whitening agents is its exceptional combination of performance features:
Superior Water Solubility: Dissolves rapidly in water with solubility of 300 g/L in boiling water and 150 g/L in cold water, enabling easy preparation and uniform distribution .
Outstanding Hard Water Resistance: The whitening effect remains stable in the presence of Ca²⁺ and Mg²⁺ ions, ensuring consistent performance even in challenging water conditions .
Excellent Bleach Compatibility: Demonstrates good resistance to peroxide bleaching agents and reductive bleaches (sodium hydrosulfite), maintaining whitening efficacy in integrated bleaching processes .
Broad PH Stability: Performs optimally across a pH range of 7-10, with good acid resistance maintaining whitening effects even at pH 3-4 .
Versatile Application Methods: Suitable for exhaust dyeing, padding, and continuous processes across textile, paper, and detergent industries .
Our Optical Brightener BBU is manufactured under strict quality controls with ≥99% purity, ensuring consistent batch-to-batch performance, minimal impurities, and compliance with international quality standards .
