It is soluble in 80 times softer water, resistant to acid and alkaline pH 6-11, dye bath pH 8-9, with increasing acidity the fluorescence gradually decreases. Resistant to hard water up to 300ppm, free chlorine up to 0.25%, not resistant to high temperature baking, not resistant to copper, iron and other metal ions. Can be used with anionic surfactants... -
Fluorescent Brightener DMS | 16090-02-1
Product Description Fluorescent brightener DMS is currently considered to be a better brightener for printing, dyeing and detergents. Due to the introduction of the morpholine gene into the molecule of this whitening agent, many of its properties have been improved. The ionisation of fluorescent brightener DMS is anionic in nature, with a fluorescent hue of cyan. Fluorescent brightener CXT has better chlorine bleaching resistance than VBL and 31#, using a good dye bath PH = 7 to 10, and ... -
