Abstract
The invention provides an aqueous colloidal peroxygen composition comprising stable sols, gels and solids of C2 to C6 peroxycarboxylic acids with a polysaccharide gum, optionally with gum cross-linking agents such as boric acid, borate salts, urea and the like useful for delivering peracids in applications such as surface cleaners, detergent bleach, automatic dish washing formulations and the like. The compositions are particularly useful for sanitizing or bleaching at an acid or neutral pH compared with other chlorine or peroxygen bleach compounds.
