WHAT DOES CONGO RED MEAN IN ENGLISH?

Congo red

Congo red

Congo red is the sodium salt of 3,3'-bis. It is a secondary diazo dye. Congo red is water soluble, yielding a red colloidal solution; its solubility is better in organic solvents such as ethanol. It has a strong, though apparently non-covalent affinity to cellulose fibers. However, the use of Congo red in the cellulose industries has long been abandoned, primarily because of its toxicity and tendency to run and change color when touched by sweaty fingers.
