A METHOD OF RENDERING A FABRIC GERMICIDAL COMPRISING THE STEPS OF: INTIMATELY CONTACTING THE FABRIC WITH A MINERAL OIL IN WATER EMULSION STABILIZED BY A NON-IONIC SUFFACE-ACTIVE EMULSIFYING AGENT SELECTED FROM THE GROUP CONSISITING OF POLYETHYLENE - GLYCOL - MONOISO - OCTYL-PHENYLETHER AND POLYOXYALKYLENE EHTER OF A PARTILAL OLEIC ACID ESTER, SAID EMULSION USED TO CONTACT SAID FABRIC CONTAINING AN AMOUNT OF MINERAL OIL EQUIVALENT TO FROM ABOUT 0.5 TO ABOUT 5 PERCENT BY WEIGHT BASED ON THE DRY FABRIC AND AN AMOUNT OF NON-IONIC SURFACE-ACTIVE EMULSIFYING AGENT EQUIVALENT TO ABOUT 2 TO 15 PERCENT BY WEIGHT BASED ON THE BLEND OF OIL AND EMULSIFYING AGENT; ADDING TO SAID EMULSION IN CONTACT WITH THE FABRIC A CATIONIC SURFACE-ACTIVE GERMICIDAL DETERGENT SELECTED FROM THE GROUP CONSISTING OF BENZALKONIUM CHLORIDE, PARATERTIARY-OCTYLPHENYL-DIETHOXY-DIMETHYL-BENZYL-AMMONIUM CHLORIDE, CETYL-DIMETHYL-BENBENZYL-AMMONIUM CHLORIDE, CETYL-DIMETHYL-BEN- GLYCINE HYZYL-AMMONIUM CHLORIDE, LAURYL-ETHYL-METHL-YL-AMIDE OF TRIMETHYL-AMMONIUM CHLORIDE, LAURYL-E HYPYRIDINIUM-IODINE, AND LAURYL ESTER OF GLYCINE HYDROCHLORIDE, SAID CATIONIC SURFACE-ACTIVE GERMICIDAL DETERGENT BEING ADDED IN AN AMOUNT EQUIVALENT TO FROM ABOUT .05 TO 1.35 PERCENT BY WEIGHT BASED ON THE DRY FABUIC; AND DRYING TO REMOVE THE WATER PHASE OF THE EMULSION FROM THE TREATED FABRIC.
