Abstract: The present invention relates to a composition comprising an aqueous solution of a) a hydrophobically modified alkylene oxide polymer comprising a hydrophobic portion functionalized with a protonated secondary or tertiary amine or a quaternary ammonium salt and b) an acid and a salt thereof, which acid is phosphoric acid, nitrilotris(methylene)triphosphonic acid, hydrochloric acid, or sulfuric acid. The composition of the present invention is useful for the preparation of an associative thickener that can be stored for long periods, in the absence of ancillary biocides, without spoilage from biodeteriogenic attack.
