  • Concentrated liquid fabric softening composition
    Patent number: 5501806
    Abstract: The pourability and softening performance of amidoamine fabric softeners, such as bis(tallow amidoethyl)-2-hydroxyethyl amine) is improved by blending with a quaternary diester fabric softener, such as N-methyl, N,N,N-triethanolamine ditallow ester quaternary ammonium salt. The amidoamine fabric softener includes at least 5% by weight of unsaturated higher alkyl groups. The compositions are concentrated with amounts of active softener compounds in excess of 25% by weight and, as such, may be used at low levels or maybe further diluted prior to use.
