Acid Blue 80 molekular structure Acid Blue 80
Acid Blue 80 is an anthraquinone type water soluble organic dye. It is likely used for coloration fabric & home care products and industrial & institutional cleaners, because its colour is stabile in wide range of pH (1-13). Also used in cosmetics for wash down types with CI 61585 name. As it shows very good resistance to high pH it is widely used in the coloration of soap bars, but also suitable for shampoos, shower gels, etc. Its absorption maximum is between 580-590 nm depending on the pH. It has excellent UV resistance.
