Abstract

Aqueous fabric softening composition having good high temperature stability comprising a cationic fabric softening compound and water soluble polysaccharide polymers comprising hydrophobic groups selected from aryl, alkyl, alkenyl, aralkyl each having at least 14 carbon atoms and cationic quaternary ammonium salt groups such that the cationic degree of substitution is from 0.01 to 0.2, the polymers having a molecular weight in the range from 100,000 to 700,000.

Claims (15)

1. An aqueous fabric softening composition comprising a cationic fabric softening compound and water soluble polysaccharide polymers comprising hydrophobic groups selected from aryl, alkyl, alkenyl, aralkyl each having at least 14 carbon atoms and cationic quaternary ammonium salt groups such that the cationic degree of substitution is from 0.01 to 0.2, the polymers having a molecular weight in the range from 100,000 to 700,000.

2. An aqueous fabric softening composition as claimed in claim 1 in which the hydrophobic groups comprise at least 16 carbon atoms.

3. An aqueous fabric softening composition as claimed in claim 1 or claim 2 in which the cationic degree of substitution is from 0.02 to 0.1.

4. An aqueous fabric softening composition as claimed in claim 1 in which the polymer has a molecular weight of at least 150,000 Da.

5. An aqueous fabric softening composition as claimed in claim 4 in which the hydrophobic groups comprise alkyl groups of 16 carbon atoms.

6. An aqueous fabric softening composition as claimed in claim 1 in which the hydrophobic group comprise from 1.0 to 2.5% by weight of the polymer.

7. An aqueous fabric softening composition as claimed in claim 1 in which the polymer has a molecular weight of from 250,000 to 550,000 Da.

8. An aqueous fabric softening composition as claimed in claim 1 in which the polymer is present in an amount of from 0.008 to 1% by weight of the composition.

9. An aqueous fabric softening composition as claimed in claim 8 in which the polymer is present in an amount of from 0.002 to 0.3% by weight of the composition.

10. An aqueous fabric softening composition as claimed in claim 1 in which the fabric softening compound is a quaternary ammonium compound.

11. An aqueous fabric softening composition as claimed claim 10 in which the fabric softening compound comprises a quaternary ammonium compound with ester linkages.

12. An aqueous fabric softening composition as claimed in claim 11 in which the fabric softening compound comprises a tallow based triethanolamine ammonium compound.

13. An aqueous fabric softening composition as claimed in claim 1 in which the fabric softening compound is present in an amount of from 0.5 to 8% by weight of the composition.

14. An aqueous fabric softening composition as claimed in claim 1 which additionally comprises a fatty alcohol or fatty acid containing from 8 to 22 carbon atoms.

15. An aqueous fabric softening composition as claimed in claim 14 which comprises from 0.3 to 2% by weight of a C 16 -C 18 fatty alcohol.
