Process for manufacturing particulate built nonionic synthetic organic

Abstract

A particulate built nonionic synthetic organic detergent 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 nonionic 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. Preferably, certain nonionic detergents, polyacetal carboxylate builders and polyphosphate, in certain proportions, are employed for better detergency and physical characteristics, e.g., flowability. Process for manufacturing the described detergent compositions are disclosed, 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. Also described are pumpable and sprayable compositions of polyacetal carboxylate builder in normally solid, liquid nonionic detergent 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.
