1. A fabric softener premix composition, said premix composition having a viscosity of less than about 1000 cps at ambient temperature, said composition being useful for preparing finished compositions, and consisting essentially of:

  • A. from about 60% to about 85% of fabric softener active selected from the group consisting of;

    1. fabric softener compound having the formula;

    
    
    space="preserve" listing-type="equation"> (R).sub.4-m --N.sup.(+) -- (CH.sub.2).sub.n --Y--R.sup.1 !.sub.m !X.sup.(-) (

         1)wherein each R substituent is a shot chain C1 -C6 alkyl or hydroxyalkyl group, benzyl, or mixtures thereof;

    each m is 2 or 3;

    each n is from 1 to about 4;

    each Y is --O--(O)C--, or --C(O)--;

    the sum of carbons in each R1, plus one when Y is --O--(O)C--, is C12 -C22 with R1 being hydrocarbyl, or substituted hydrocarbyl, stibstituent; and

    the iodine Value of a fatty acid which contains this R1 group is from about 60 to about 140, and wherein said softener active can comprise up to about 20% of inonoester compound in which m is 2 and one YR1 is H or --C(O)OH;

    2. fabric softener compound having the formula;

    ##STR7## wherein each Y, R, R1, and X.sup.(-) have the same meanings as before and wherein said softener active can comprise up to about 20% of monoester compound in which one YR1 is 11 or --C(O)OH; and
