Abstract
Abstract The present invention relates to solid magnesium peroxycarboxylate salts and detergent compositions containing them. These compounds have markedly improved stability characteristics relative to the corresponding peroxycarboxylic acids, especially when admixed with alkaline granular detergent products. The activity of the magnesium peroxycarboxylate salts after dissolution is the same as that of the corresponding peroxycarboxylic acids, especially when used as laundry bleaches. The compound within this invention also have improved odor and dissolution characteristics relative to the corresponding peroxycarboxylic acids.
