LAUNDRY RINSES AND DRYER SHEETS

摘要

An N-alkyl-N,N-dimethylamine oxide is used together with N,N-dihydrogenated-tallow-N,N-dimethylammonium chloride to provide an improved fabric softener product which has synergistic properties and which is (1) a laundry rinse which comprises an aqueous solution of a mixture of 25-80 % by weight of the quaternary ammonium chloride and 75-20 % by weight of N-octadecyl-N,N-dimethylamine oxide or (2) a laundry dryer sheet which comprises a flexible absorbent substrate impregnated with a mixture of 10-80 % by weight of the quaternary ammonium chloride and 90-20 % by weight of an N-alkyl-N,N-dimethylamine oxide wherein the alkyl is octadecyl when the amine oxide constitutes 20-40 % of the mixture and otherwise may be any primary alkyl group containing 8-24 carbons.
