ABSTRACT OF THE DISCLOSURE A particulate built nonionic synthetic organic deter- gent composition includes a detersive proportion of a nonionic synthetic organic detergent and a building proportion, in combination, of a polyacetal carboxylate builder for the nonionic detergent and a polyphosphate builder for such non- ionic detergent. Such compositions are readily made by adding polyacetal carboxylate builder to the formula of a control detergent composition, with corresponding diminutions of other component(s), and have detersive powers superior to such control despite the decrease in detergent and other builders. Prefer- ably, certain nonionic detergents, polyacetal carboxylate builders and polyphosphate, in certain proportions, are employed for better detergency and physical characteristics, e.g. flowability. Also disclosed are processes for manufactur- ing the described detergent compositions, in which processes spray dried builder base beads, containing polyphosphate builder salt, have nonionic detergent and polyacetal carboxylate builder mixed with or applied to them. Additionally des- cribed are pumpable and sprayable compositions of polyacetal carboxylate builder in normally solid, liquid nonionic deter- gent at elevated temperature, which compositions are suitable for applying the nonionic detergent and polyacetal carboxylate builder to spray dried polyphosphate base beads, preferably as a spray onto moving surfaces of such beads.
