摘要： The present invention relates to aqueous compositions having pH of less than or equal to about 11 and which contain a thickening amount of an acrylate-based rheology modifier, which modifier contains an emulsion which is prepared by single-stage emulsion polymerization of a C2-C6alkyl ester of acrylic acid and/or C1-C6alkyl ester of methacrylic acid, a monomer chosen from a vinyl-substituted heterocyclic compound containing at least one of a nitrogen or sulfur atom, (meth)acrylamide, a mono- or di-(C1-C4)alkylamino (C1-C4)alkyl (meth)acrylate, a mono or di-(C1-C4)alkylamino (C1-C4)alkyl (meth)acrylamide, and optionally cross-linking monomers and/or associative monomers, in the presence of water, a first surfactant, a free-radical initiator and an alcohol selected from C2-C12 linear or branched alcohols, ethylene glycol, propylene glycol and glycerol, or mixtures thereof, and essentially in the absence of a polymeric colloidal stabilizer such as polyvinyl alcohol, and which compositions further contain an active ingredient selected from the group consisting of an acid and a second surfactant which may be the same as or different than the first surfactant.
