An aqueous fabric softening composition is described having its rheological properties
of flow elasticity and viscosity capable of being readily modified as needed independently
of each other to satisfy a consumer preference, said composition comprising:
- a) from about 0.01% to about 25%, by weight, of a cationic fabric softener;
- b) an effective amount of a mixture of cationic polymers capable of
modifying the aforesaid rheological properties, said mixture comprising:
- (iii) from about 0.01% to about 90%, by weight, of a cationic linear
homopolymer that is derivable from the polymerization of acrylic acid and/or methacrylic
acid or a linear copolymer that is derivable from the polymerization of acrylic
acid and/or methacrylic acid and acrylamide or methacrylamide, said homopolymer
or copolyer having a molecular weight of from about 10,000 to about 30 million; and
- (iv) from about 10% to about 99.99%, by weight, of a cationic cross-linked
polymer that is derivable from the polymerization of, from 5 to 100 mole percent
of cationic vinyl addition monomer, from 0 to 95 mole percent of acrylamide, and
from 70 ppm to 300 ppm of a difunctional vinyl addition monomer cross linking agent,
the respective amounts of (i) and (ii) in said mixture being selected to provide
the desired rheological properties of viscosity and flow elasticity in said softening
composition; and
- c) balance water.
