Uses in Dye Industry
This stain was originally discovered by ICI in 1940s as a member of the competitive dye industry for the purpose of industrial dying. It was used for some time for staining textiles, leather products and inks. ICI sold thousands of tons of alcian blue and filed multiple patents regarding its manufacturing process to keep its chemistry a tight secret. However ICI had had trouble with the dye's solubility under textile dyeing conditions, and various process changes in manufacturing were made during the 1950s and 1960s.
