Abstract
The invention pertains to an aqueous composition having a pH of 3 or less and comprising the following ingredients, based on the total weight of the composition: a) 0.05-40 wt % of a polymeric thickener having —COOR groups, wherein R is independently chosen from H, OH, and a carbon-containing group, and b) 0.05-60 wt % of hydrogen peroxide, wherein the active oxygen content attributable to ingredient a) is at least 0.02 wt %, based on the total weight of the composition, with the proviso that (co)polymers prepared from (meth)acrylate monomers are absent.
Claims21
An aqueous composition having a pH of 3 or less and comprising the following ingredients, based on the total weight of the composition:
- a) 0.05-40 wt % of a polymeric thickener having —COOR groups, wherein R is independently chosen from H, OH, and a carbon-containing group, and
- b) 0.05-60 wt % of hydrogen peroxide,
- wherein the active oxygen content attributable to the ingredient a) is at least 0.02 wt %, based on the total weight of the composition, with the proviso that (co)polymers prepared from (meth)acrylate monomers are absent.
An aqueous composition having a pH of 3 or less and comprising the following ingredients, based on the total weight of the composition:
- a) 0.05-20 wt % of a polymeric thickener having 20-100,000 monomeric units and on average containing at least 0.8 —COOR groups per monomeric unit, wherein R is independently chosen from H, OH, and a carbon-containing group,
- b) 0.05-30 wt % of hydrogen peroxide, and
- c) 0.5-60 wt % of one or more aliphatic carboxylic acids having 1 to 8 carbon atoms, their alkyl esters, anhydrides, and/or peroxyacids,
- wherein the active oxygen content attributable to ingredients a) and c) is at least 0.02 wt %, based on the total weight of the composition.
