ABSTRACT:

TECHNICAL FIELD
The present invention relates to concentrated, preferably translucent, or, more preferably, clear, aqueous, liquid softening compositions useful for softening cloth. It especially relates to testile softening compositions for use in the rinse cycle of a textile laundering operation to provide excellent fabric-softening static-control benefits.
BACKGROUND OF THE INVENTION
Concentrated clear compositions containing ester and/or amide linked fabric softening actives are disclosed in co-pending application Ser. No. 08/679,694, filed Jul. 11, 1996 in the names of E. H. Wahl, T. Trinh, E. P. Gosselink, J. C. Letton, and M. R. Sivik, for Fabric Softening Compound/Composition, said application being incorporated herein by reference. The fabric softener actives in said applications are all biodegradable ester-linked materials, containing, as long hydrophobic groups, both unsaturated and branched chains. They are also, for the most part, quaternary ammonium compounds.
SUMMARY OF THE INVENTION
The amine fabric softener compositions herein comprise:
A. from about 2% to about 80% of water insoluble amine fabric softener active containing at least two C
6
-C
22
hydrocarbyl groups, but no more than one being less than C
12
and then the other is at least C
16
, the groups having an IV (Iodine Value) of 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 fabric softner active;
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.
Preferably, the compositions are aqueous, stable clear or dispersion fabric softener composition containing:
A. from about 2% to about 80%, preferably from about 13% to about 75%, more preferably from about 17% to about 70%, and even more preferably from about 19% to about 65%, by weight of the compositions, of amine fabric softener active which is selected from:
