The present invention relates to a novel alkali swellable thickening emulsion that does not contain a solvent other than a surfactant and water: as a result, everything related to the use of a solvent or the formation of foam when using a surfactant The disadvantages are avoided. This new emulsion contains an amount of 2-acrylamido-2-methylpropane sulfonic acid (i.e., AMPS, CAS number: 40623-75-4). These emulsions have been found to be effective in thickened aqueous media, especially water-based paints, paper coatings, aqueous suspensions of inorganic materials, detergents, cosmetic formulations or formulations containing hydraulic binders. ing. |
