    Abstract: Liquid formulations of mixtures of cationic dyes frequently have a very short storage life. As a consequence, these formulations give rise to customer complaints concerning incorrect dyeing strengths and hues and concerning isoluble constituents. It has now been found according to the invention that powder formulations and in particular liquid formulations of cationic dyes or of mixtures of these dyes can be stabilized by adding selected oxidizing agents.
