Product Name:Fluorescent Brightener VBL
English Name:Fluorescent Brightener VBL
CAS No.:12224-16-7
Aliases:Fluorescent Brightening Agent VBL, Optical Brightener VBL, C.I. Fluorescent Brightener 85
Molecular Formula:C36H34O8N12S2Na2
Physical Properties:Pale yellow to yellow uniform powder; relative molecular mass 872.84; UV absorption wavelength 348 nm. Soluble in 80 times its weight of soft water, showing anionic properties. Stable at pH 6–11, optimum dyebath pH 8–9. Tolerates hard water up to 300 ppm and free chlorine up to 0.25%; sensitive to copper and iron ions. Stable to sodium hydrosulfite but not resistant to high-temperature baking. Fluorescent shade is blue-violet.
Uses:It is suitable for brightening white cotton and viscose fiber products and enhancing light-colored or printed goods, with good affinity for cellulose fibers. It can also be used for brightening vinylon and nylon products, as well as for pulp and coating brightening in the paper industry. For dyeing and printing, it is directly dissolved in water before adding to the dyebath; for papermaking, it is dissolved in 80 times water and then added to pulp or coating.
Technical Specifications:
Appearance: pale yellow to yellow uniform powder.
UV absorption wavelength: 348 nm.
Fluorescence intensity and relative strength (relative to standard): both ≥100.
Moisture content ≤5.0%; water-insoluble content ≤0.5%.
Fineness (residue through 250 μm aperture sieve) ≤8.0%.
