Abstract (en)
[origin: EP0508543A1] The present invention relates to a process for making a free flowing granular detergent composition comprising : a) neutralising anionic surfactant acid or acids in an excess of alkali to give a high active paste, said paste having a viscosity of at least 10 Pa.s when measured at 70 DEG C and a shear rate of 25 s<-><1> b) conditioning said paste c) forming high active detergent granules in a high shear mixer/granulator in the presence of an effective of detergent powder.
