Abstract
Under conditions of misuse, water-soluble peroxyacids when they are left in direct contact with dyed fabrics can cause spotting and dye damage. The problem can be ameliorated by surface-treating the peroxyacid with an effective amount, preferably selected in the range of 8 to 25% w/w based on the peroxyacid, of aliphatic amines which melt or soften at about 30.degree. to 70.degree. C. Preferred agents include hydrogenated tallow amine dicocoamine and methyl dihydrogenated tallow amine. The agent can be applied in molten fashion or in inert solvent such as a chlorinated aliphatic hydrocarbon onto agitated particles of the peroxyacid.
