Abstract:
Amine fabric softener compositions comprising:A. from about 2% to about 80% of water insoluble amine fabric softener active containing at least two C6-C22 hydrocarbyl groups, but no more than one being less than C12 and then the other is at least C16, the groups having an IV from about 0 to about 140, the groups comprising straight and/or branched chain hydrocarbon groups, said amine softener active being neutralized by an acid; and B. at least one material to increase the cationic charge density of said amine fabric softener active, said material being selected from the group consisting of: (1) polycationic compound; (2) acid less than about 40% by weight of the fabric softening composition to lower the rinse water pH by at least about 0.5, wherein said acid is a material selected from the group consisting of: a) a mineral acid in an amount greater than about 5.8%; b) an organic acid in an amount greater than about 20%; or c) a mixture of mineral acid in an amount greater than about 4% and organic acid in an amount of greater than about 13%; and (3) mixtures thereof; C. optionally, from about 2% to about 60% of quaternary ammonium softener active; D. optionally, less than about 40% by weight of the composition of principal solvent having a ClogP of from about 0.15 to about 0.64, and at least some degree of asymmetry; and E. aqueous solvent.
