Abstract: The invention relates to a process for producing a pulverulent composition comprising at least one polymeric dispersant (PD) which comprises structural units having anionic and/or anionogenic groups and structural units having polyether side chains, and at least one polysaccharide (PS). The process here comprises the process steps: a) production of an aqueous dispersion having a viscosity of the dispersion of less than 10 000 mPa·s, comprising the at least one polymeric dispersant (PD) and the at least one polysaccharide (PS) and b) spray drying of the aqueous dispersion produced in process step a). Furthermore, the use of the pulverulent composition according to the invention in inorganic binder compositions, especially as a rheological additive, is disclosed.
