Abstract

A fabric care composition is provided, comprising: a fabric care benefit agent; and a deposition aid polymer is provided, comprising >50 to 99 wt % of structural units of formula (I)

wherein R 1 is selected from hydrogen, —C 1-4 alkyl and —CH 2 OR 3 ; wherein R 3 is selected from —C 1-12 alkyl and phenyl; and 1 to <50 wt % of structural units of formula (II)

wherein R 2 is selected from Formula (III), Formula (IV) and Formula (V)

wherein A − is a counter anion; wherein R 4 is selected from a hydrogen, a —C 1-12 alkyl group and a phenyl group; and wherein R 5 is selected from a hydrogen and a —C 1-8 alkyl group; wherein the deposition aid polymer has a weight average molecular weight of <100,000 Daltons; and with the proviso that the deposition aid polymer has an average of ≥two structural units of formula (II) per molecule.

First claim

We claim:

1. A fabric care composition comprising:
a fabric care benefit agent; and
1 to 5 wt %, based on weight of the fabric care composition, of a deposition aid polymer, comprising:
(a) 82 to 96 wt %, based on weight of the deposition aid polymer, of structural units of formula (I)

wherein each R 1 is independently selected from the group consisting of a hydrogen and a methyl group; and
(b) 4 to 18 wt %, based on weight of the deposition aid polymer, of structural units of formula (II)

wherein each R 2 is independently selected from the group consisting of a moiety of Formula (III), a moiety of Formula (IV) and a moiety of Formula (V)

wherein A − is a counter anion balancing the cationic charge on the N; wherein each R 4 is independently selected from the group consisting of a hydrogen and a C 1-2 alkyl group; and wherein each R 5 is a hydrogen;

wherein the deposition aid polymer has a weight average molecular weight of <100,000 Daltons; and with the proviso that the deposition aid polymer has an average of 3 to 20 structural units of formula (II) per molecule.

2. The fabric care composition of claim 1 , wherein the fabric care composition comprises
2.5 to 6 wt %, based on weight of the fabric care composition, of the fabric care benefit agent; wherein the fabric care benefit agent is a fabric softening silicone selected from the group consisting of a nitrogen free silicone polymer, an anionic silicone polymer and mixtures thereof; and
2 to 3 wt % of the deposition aid polymer, comprising:
(a) 90 to 95 wt %, based on weight of the deposition aid polymer, of structural units of formula (I); wherein each R 1 is a hydrogen; and
(b) 5 to 10 wt %, based on weight of the deposition aid polymer, of structural units of formula (II); wherein each R 4 is a methyl group; wherein each R 5 is a hydrogen; and with the proviso that the deposition aid polymer has an average of 3.5 to 15 structural units of formula (II) per molecule.

3. The fabric care composition of claim 2 , further comprising: a builder and a cleaning surfactant.

4. The fabric care composition of claim 3 , further comprising: a liquid carrier.

5. The fabric care composition of claim 4 , wherein the fabric care benefit agent is a fabric softening silicone selected from the group consisting of nitrogen free silicone polymers and anionic silicone polymers.

6. The fabric care composition of claim 5 , wherein the fabric care composition is a laundry detergent.

7. The laundry detergent of claim 6 , wherein the cleaning surfactant is selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants and mixtures thereof.

8. The laundry detergent of claim 7 , wherein the cleaning surfactant includes a mixture of a linear alkyl benzene sulfonate, a sodium lauryl ethoxysulfate and a nonionic alcohol ethoxylate.

9. A method of treating an article of laundry, comprising: providing an article of laundry; providing a fabric care composition according to claim 1 ; providing a bath water; and applying the bath water and the fabric care composition to the article of laundry to provide a treated article of laundry; wherein the fabric care benefit agent is associated with the treated article of laundry.

10. The method of claim 9 , wherein the fabric care composition is according to claim 8 .

11. The fabric care composition of claim 1 , wherein the deposition aid polymer has a weight average molecular weight of 5,000 to 30,000 Daltons.

12. The fabric care composition of claim 11 , wherein the fabric care composition comprises
2.5 to 6 wt %, based on weight of the fabric care composition, of the fabric care benefit agent; wherein the fabric care benefit agent is a fabric softening silicone selected from the group consisting of a nitrogen free silicone polymer, an anionic silicone polymer and mixtures thereof; and
2 to 3 wt % of the deposition aid polymer, comprising:
(a) 90 to 95 wt %, based on weight of the deposition aid polymer, of structural units of formula (I); wherein each R 1 is a hydrogen; and
(b) 5 to 10 wt %, based on weight of the deposition aid polymer, of structural units of formula (II); wherein each R 4 is a methyl group; wherein each R 5 is a hydrogen; and with the proviso that the deposition aid polymer has an average of 3.5 to 15 structural units of formula (II) per molecule.

13. The fabric care composition of claim 12 , further comprising: a builder and a cleaning surfactant.

14. The fabric care composition of claim 13 , further comprising: a liquid carrier.

15. The fabric care composition of claim 14 , wherein the fabric care benefit agent is a fabric softening silicone selected from the group consisting of nitrogen free silicone polymers and anionic silicone polymers.

16. The fabric care composition of claim 15 , wherein the fabric care composition is a laundry detergent.

17. The laundry detergent of claim 16 , wherein the cleaning surfactant is selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants and mixtures thereof.

18. The laundry detergent of claim 17 , wherein the cleaning surfactant includes a mixture of a linear alkyl benzene sulfonate, a sodium lauryl ethoxysulfate and a nonionic alcohol ethoxylate.

19. A method of treating an article of laundry, comprising: providing an article of laundry; providing a fabric care composition according to claim 11 ; providing a bath water; and applying the bath water and the fabric care composition to the article of laundry to provide a treated article of laundry; wherein the fabric care benefit agent is associated with the treated article of laundry.

20. The method of claim 19 , wherein the fabric care composition is according to claim 18 .
