Abstract of the Disclosure 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 carbonate, bicarbonate and zeolite builders for such nonionic detergent. Such compositions may readily be made by adding polyacetal carboxylate builder to the formula of a control detergent composition, with corresponding diminutions in proportions of other component(s), and have detersive powers superior to such control despite the decrease in proportions present of detergent and other builders. Preferably, certain nonionic detergents, polyacetal carboxylate builders, carbonate, bicarbonate and zeolite, in certain proportions, are employed to make a product of better detergency and physical characteristics, e.g., flowability. Also disclosed are processes for manufacturing the described detergent compositions, in which processes spray dried builder base beads, containing carbonate, bicarbonate and zeolite builder salts, have nonionic detergent and polyacetal carboxylate builder (sometimes with additional zeolite) mixed with or applied to them. Additionally described are pump able and sprayable compositions of poly- acetal carboxylate builder in normally solid, liquid nonionic detergent at elevated temperature, which compositions are suitable for applying the nonionic detergent and polyacetal carboxylate builder (sometimes with additional zeolite being present) to the spray dried carbonate-bicarbonate-zeolite base beads, preferably as a spray impinging on moving surfaces of such beads. - 2 -
