Abstract

A fabric care composition comprises a polymeric material which is capable of self cross-linking and/or of reacting with cellulose together with one or more textile compatible carriers, wherein the polymeric material comprises one or more poly(oxyalkylene) groups having an end group which comprises one or more amino groups or derivatives of said amino groups.
The compositions may be used to treat fabric as part of a laundering process and improve the surface colour definition of the fabric following multiple washings.

Claims

1. Use of a fabric care composition to improve the surface colour definition of a fabric after multiple washings and/or to impart pill and/or fuzz resistance to fabric during laundering; wherein the composition comprises a polymeric material which is capable of self cross-linking and/or of reacting with cellulose together with one or more textile compatible carriers, wherein the polymeric material comprises one or more poly(oxyalkylene) groups having an end group which comprises one or more amino groups or derivatives of said amino groups, and wherein when the textile compatible carrier is water a further additive suitable for use in laundry compositions is present.

2. Use as claimed in Claim 1, wherein the polymeric material is obtainable by the reaction of (i) a polymer of formula B(R)n, wherein n is from 1 to 20, B is a backbone group to which each R is covalently bonded and R is a group comprising a poly(oxyalkylene) chain, which chain comprises an amino end group, with (ii) a cross-linking agent, the polymer being optionally reacted with a bridging compound prior to reaction with the cross-linking agent.

3. Use as claimed in Claim 2, wherein n is 2 or 3.

4. Use as claimed in Claim 2 or Claim 3, wherein B is and m is equal to n-2.

5. Use as claimed in any one of Claims 2 to 4, wherein at least one R group has the formula -(CH2CH(R')(CH2)~O)p-A-NHR", wherein. R' is H or CH3; a is 0, 1 or 2;
p is an integer from 5 to 30; A is an alkylene group; and R" is H or alkyl.

6. Use as claimed in Claim 5, wherein p is from 10 to 25.

7. Use as claimed in any one of Claims 2 to 6, wherein the polymer of formula B(R)n is wherein p, q and r are integers which may be the same or different and may be from 5 to 30 and A is branched or unbranched lower alkylene.

8. Use as claimed in any one of Claims 2 to 6, wherein the polymer of formula B(R)n is H2N-(CH2)b-(O(CH2)4)d-O(CH2)~-(O-((CH2)4O)d2-(CH2)d-NH2 wherein: b is an integer from 1 to 6; c is an integer from 1 to 6; and d and d2 are the same or different and are integers from 10 to 15.

9. Use as claimed in Claim 8, wherein b is 3 and/or c is 4.

10. Use as claimed in any one of Claims 2 to 9, wherein the cross-linking agent comprises an epihalohydrin.

11. Use as claimed in any one of Claims 2 to 10 wherein the molar ratio of cross-linking agent to polymer of formula B(R)n is from 0.5:1 to 4:1.

12. Use as claimed in any one of Claims 2 to 11, wherein the bridging compound comprises two epoxide or carboxylic acid groups.

13. Use as claimed in Claim 12, wherein the epoxide or carboxylic acid groups are linked by a linker comprising alkylene, arylene, poly(oxyalkylene) or siloxane groups or combinations thereof.

14. Use as Claimed in any one of Claims 1 to 13 further comprising a silicone which is capable of reacting with the polymeric material.

15. Use as claimed in any one of Claims 1 to 14, wherein the polymeric material is capable of increasing the wet strength of paper by at least 200 compared to untreated paper when applied to paper having a weight of 80 g/m2 at a level of 1% solids by weight based on weight of paper.

16. Use as claimed in any one of Claims 1 to 15, wherein the one or more textile compatible carriers comprise a detergent active compound.

17. Use as claimed in any one of Claims 1 to 15, wherein the one or more textile compatibles carriers comprise a fabric softening and/or conditioning compound.

18. Use as claimed in any one of Claims 1 to 17, further comprising a perfume.

19. Use as claimed in any preceding claim wherein the fabric comprises cellulosic fibres.

20. A method of treating fabric, as part of a laundering process, in order to improve the surface colour definition of a fabric after multiple washings and/or to impart pill and/or fuzz resistance to fabric during laundering which comprises applying to the fabric a fabric care composition and/or a polymeric material as defined in any one of Claims 1 to 18.

21. A method as claimed in Claim 20 wherein the composition is applied to the fabric during a wash cycle.

22. A method as claimed in Claim 20, wherein the composition is applied to the fabric during a rinse cycle.
