Zusammenfassung:The invention relates to a thickening agent P for an aqueous composition, in particular for a hydro-alcoholic composition. The thickening agent P is prepared in the absence of acrylamide by a polymerisation reaction using N-methylol acrylamide or one of the derivatives thereof, an acid and an acid ester. A specific condensate of (meth)acrylic acid and N-methylol acrylamide are part of the invention. The invention also provides a hydro-alcoholic composition, the viscosity of the hydro-alcoholic composition being controlled.The invention also provides a hydro-alcoholic composition, the viscosity of the hydro-alcoholic composition being controlled.
