  • Patent number: 5460736
    Abstract: The present invention relates to a solid particulate or liquid rinse-added fabric softening composition containing specific chlorine scavengers. The solid particulate composition, comprises from about 50% to about 95%, by weight of the composition, of biodegradable, cationic quaternary ammonium fabric softening compound and an effective amount of chlorine scavenger selected from the group consisting of: amines; ammonium salts; amino acids, but not lysine; polyamino acids; polyethyleneimines; polyamines, but not di(higher alkyl)cyclic amines nor their condensation products; polyamineamides; polyacrylamides; and mixtures thereof. The solid particulate composition further comprises from about 0% to about 30%, by weight of the composition, of a modifier, for viscosity, dispersibility, or both; and from about 0% to about 20%, by weight of the composition, of a pH modifier. The liquid composition comprises from about 0.

  • Patent number: 5427697
    Abstract: The present invention relates to clear or translucent, rinse-added fabric softening compositions comprising from about 20% to about 80% imidazoline, imidazolinium, and/or di(2-amidoethyl)methyl quaternary ammonium fabric softener active, from about 2% to about 25% C.sub.8 -C.sub.22 mono-alkyl cationic quaternary ammonium compound dispersibility aids, and from about 17% to about 75% non-aqueous organic solvent, wherein the fatty acyl groups of the softener active have an average Iodine Value of at least about 50. Preferably the compositions have a viscosity of from about 15 cps to about 500 cps when diluted with from about 1:1 to about 1:5, softening composition to water.

  • Patent number: 4855072
    Abstract: Liquid fabric softening compositions for use in a rinse bath after washing fabrics with a detergent. The softening compositions contain (a) the reaction products of higher fatty acids with a polyamine selected from the group consisting of hydroxyalkylalkylenediamines and dialkylenetriamines and mixtures thereof, (b) cationic nitrogenous salts having only one long chain acyclic aliphatic hydrocarbon group, and optionally (c) cationic nitrogenous salts having two or more long chain acyclic aliphatic hydrocarbon groups or one said group and an arylalkyl group; these compositions provide good softening performance across major types of detergents.
