Abstract:
A stabilized thickened aqueous bleach composition comprising, by weight;a. from about 0.1% to 50% of an alkali metal hypohalite bleach oxidizing agent;b. from about 0.01% to about 10% of a polymeric rheology modifying agent, wherein said polymeric rheology modifying agent is a homopolymer or a copolymer or a cross-linked polymer or a cross-linked copolymer of an olefinically unsaturated carboxylic acid, or an anhydride monomer containing at least one activated carbon to carbon olefinic double bond and at least one carboxy group, or is an alkali soluble acrylic emulsion, or a hydrophobically modified alkali soluble acrylic emulsion, or a hydrophobically modified nonionic polyol polymer, or a combination thereofc. from about 0.001% to about 10% of a rheology stabilizing agent having the formula ##STR3## wherein X is OCH.sub.3 or CH:CHCOO.sup.- M.sup.- or H; and each A, B, and C is H or OH, or OCH.sub.3, or CH.sub.3, or CHO, or CH.sub.2 OH, or COOCH.sub.3, or COOC.sub.1-4 H.sub.3-9, or OC.sub.1-4 H.sub.3-9, or C.sub.1-4 H.sub.3-9, or OCOCH.sub.3, or NH.sub.2, or mixtures thereof; and M is H or an alkali metal or ammonium;d. sufficient alkalinity buffering agent to provide said composition with a pH from about 10 to about 14; ande. water.
