  • Patent number: 4772404
    Abstract: A concentrated fabric softener having a dual cationic high active system, a sufficient level of fluorescent dye to whiten cotton garments, and a non-ionizing base. The dual active system is included at levels of greater than about 10% and preferably comprises a difatty amido ammonium methyl sulfate and a ditallow dimethyl ammonium chloride in a ratio of at least 1.5:1. Use of the concentrated softener results in reduced container size and greater manufacturing efficiencies. Inclusion of fluorescent dye restores whiteness/brightness to cotton garments yellowed by age.
