The present invention relates to an aqueous composition having a pH of about 11 or less, including a thickening content of an acrylate flow modifier, wherein the modifier is a C 2 to C 6 alkyl ester of acrylic acid and / or a C 1 to C 6 alkyl of methacrylic acid. Vinyl-substituted heterocyclic compounds comprising at least one of an ester, nitrogen or sulfur element, (meth) acrylamide, mono- or di- (C 1 -C 4 ) alkylamino (C 1 -C 4 ) alkyl ( A monomer selected from meth) acrylate, mono or di- (C 1 -C 4 ) alkylamino (C 1 -C 4 ) alkyl (meth) acrylamide, and optionally a crosslinking monomer and / or associative monomer. a first surfactant, free radical initiator and a C 2 ~C 12 straight-chain or branched essentially the same as the polyvinyl alcohol in the presence of an alcohol selected from the ground alcohol, ethylene glycol, propylene glycol, and glycerol, or mixtures thereof An emulsion prepared by single stage emulsion polymerization in the absence of a polymeric colloidal stabilizer, the composition further comprising an active ingredient selected from the group consisting of an acid and a second surfactant which may be the same as or different from the first surfactant.
