United Specialities Fluorescent Whitening Agent

Excellent Whiteness Maximum
• Owing to its high yield, Luminophore ERI, is very economical.
• Luminophore ERI can exhibit very good suitability by exhaustion or padding process.
• Luminophore ERI, as dispersed in water, is neutral and stable to acids and alkalis, giving good optical
whitening effect at a wide range of pH value (3.0 to 9.0)
• Luminophore ERI has an inherent reddish hue, additions of a violet disperse dye, 0.1% to 0.2% on the
weight of Luminophore ERI would help increase whiteness and adjust colour shade.
• Luminophore ERI exhausts almost completely under HT conditions. It has low affinity at the boil but
uptake can be improved by addition of suitable carriers.
