Synonyms Used in print (Jay C. Harris and John R.

In the household market , there are also low-sudsing detergent formulations based on nonionic actives with about the same amount of phosphate builder ; light-duty synthetic detergents with much less builder ; and the dwindling built soap_powders as_well_as soap_flakes and granules , none of which are now nationally advertised . A well publicized entrant which has achieved success only recently is the built liquid_detergent , with which the major problem today is incorporation of builder and active into a small volume using a sufficiently high builder / active ratio .
