Abstract

A thickened bleach composition that is both viscous and elastic. The composition provides the benefits of both Theological characteristics. The composition has utility as a drain opening composition or as a hard or soft surface cleaner having a cleaning-effective residence time on non-horizontal surfaces. The composition preferably has a relative elasticity less than 10 sec/Pa and a 0 Hertz viscosity greater than 1500 cP. The composition also preferably has a relaxation time of 1 second or greater and a static shear modulus greater than 2 Pa.

Claims

1. A thickened bleach composition having a relative elasticity less than about 10 sec/Pa and a 0 Hertz viscosity greater than about 1500 cP.

2. The bleach composition of claim 1 wherein the bleach comprises hypochlorite or a hypochlorite generating species.

3. The bleach composition of claim 2 having a relative elasticity less than about 5 sec/Pa and a 0 Hertz viscosity greater than about 2000 cP.

4. The bleach composition of claim 1 having a relative elasticity less than about 5 sec/Pa and a 0 Hertz viscosity greater than about 2000 cP.

5. The bleach composition of claim 1 having a relative elasticity between about 0.1 and 10 sec/Pa and a 0 Hertz viscosity greater than about 1500 cP.

6. The bleach composition of claim 1, wherein said composition is used as a drain cleaner.

7. The bleach composition of claim 1, wherein said composition is used to clean hard surfaces.

8. The bleach composition of claim 1, wherein said composition is used to clean fabric.

9. A thickened bleach composition having a relaxation of about 1 second or greater and a static shear modulus greater than about 2 Pa.

10. The bleach composition of claim 9, wherein the bleach comprises hypochlorite or a hypochlorite generating species.

11. The bleach composition of claim 10 having a relaxation of about 3 seconds or greater and a static shear modulus greater than about 3 Pa.

12. The bleach composition of claim 9 having a relaxation of about 3 seconds or greater and a static shear modulus greater than about 3 Pa.

13. The bleach composition of claim 9 having a relaxation of about 3 seconds or greater and a static shear modulus greater than about 4 Pa.

14. The bleach composition of claim 9, wherein said composition is used as a drain cleaner.

15. The bleach composition of claim 9, wherein said composition is used to clean hard surfaces.

17. A method of cleaning drains comprising introducing into the drain an effective amount of a liquid drain cleaner consisting essentially of a thickened bleach composition having a relative elasticity less than about 10 sec/Pa and a 0 Hertz viscosity greater than about 1500 cP.

18. The method of cleaning drains of claim 17, wherein the bleach comprises hypochlorite or a hypochlorite generating species.

19. The method of cleaning drains of claim 17, wherein the bleach composition has a 0 Hertz viscosity greater than about 2000 cP.

20. The method of cleaning drains of claim 17, wherein the bleach composition has a relaxation of about 1 second or greater.
