The physical routes which lead to fading are outlined and the appropriate formulation principles are discussed. Dye fading in heavy duty detergent products at low temperatures arises primarily from oxidative destruction of the dye chromophore by peracids, generated from hydrogen peroxide bleach in situ. The underlying principles of oxidative dye destruction by detergent bleaches are now so advanced that oxidative dye fading can be avoided by careful dye selection.
