Abstract
Abstract Novel fabric softening compounds of the formulae , and wherein R and R 2 are independently selected from the group consisting of aliphatic radicals containing from about 8 to about 22 carbon atoms, R 3 and R 4 are independently selected from the group consisting of hydrogen and methyl, R s is selected from the group consisting of hydrogen and aliphatic radicals containing from about 8 to about 22 carbon atoms, x and y are independently integers from 1 to about 20, and z is 0 or 1 are disclosed. Also disclosed is a method for conditioning textiles utilizing said compounds.
