Quinoline Yellow SS is used in spirit lacquers, polystyrene, polycarbonates, polyamides, acrylic resins, and to color hydrocarbon solvents. It is also used in externally applied drugs and cosmetics. Quinoline Yellow SS is used in some yellow colored smoke formulations.
When sulfonated, it forms a water soluble derivate, Quinoline Yellow WS.
Famous quotes containing the word yellow:
“He’s made a harp of her breast-bane,
Whose sound wad melt a heart of stane.
He’s ta’en three locks o’ her yellow hair,
And wi’ them strung his harp sae rare.”
