The purposes of the present work are to analyze the rheological characteristics of a detergent slurry containing pentasodium triphosphate (TPP) and to study the influence that some factors exert on the rheological consistency of this slurry. Experimental results were achieved using a Brabender Plastograph and have been analyzed according to approximate methods to convert torque‐rheometer data into fundamental rheological units. From the experimental results it can be inferred that: (i) The systems studied exhibit plastic rheological behavior at steady shear and a progressive decrease in consistency by increasing shear rate; (ii) an increase in the yield value and apparent viscosity of the slurry are produced by increasing the concentration of nonaqueous substances or the phase I/phase II TPP ratio; and by decreasing the temperature or the hydrotrope content; (iii) the effect that temperature and concentration exert on the rheological consistency of the slurry may be quantified according to the usual equations found in the references.
