A method for obtaining a cleaning material characterized in that it comprises the product of the steric reaction of at least one hydroxide equivalent of an ionic surfactant containing at least one hydroxide group, with no more than four carboxylic acid equivalents of a material unsaturated polycarboxylic acid or the corresponding sulfoacid material, the ester thus obtained being converted into the corresponding sulfonate salt, the unsaturated polycarboxylic acid being obtained by a process comprising the pyrolyzing of an alkaline earth citrate at a temperature of 250ºC for a determined period of time, until achieving an increase in the titratable alkalinity of the reaction mixture and converting the unsaturated salt material thus achieved into the corresponding acidic material.
