Abstract

A two-compartment dispenser comprising a first compartment containing an aqueous composition comprising hydrogen peroxide or an organic peracid and a second compartment containing an alkalizing agent additionally comprise sufficient surfactant, including any super wetting agent, the two compartment containing sufficient surfactant (and super wetting agent, if present) to achieve a surface tension of below 28 mN/m upon mixing.

Claims

1. A process for stain removal on a carpet, comprising applying to the carpet a mixture of at least two components (a) and (b):

(a) an aqueous composition comprising a source of active oxygen having a pH of greater than 0 but less than 7 and

(b) an aqueous composition comprising an alkalizing agent.

2. A process according to claim 1 wherein component (a), component (b) or both components (a) and (b) additionally comprise sufficient surfactant, including any super wetting agent, to achieve a surface tension of the combined composition of below 28 mN/m.

3. A process according to claim 1 wherein component (a), component (b) or both components (a) and (b) additionally comprise a superwetting agent.

4. A process according to claim 2 claim wherein the surfactant is a non-ionic surfactant.

5. A process according to claim 4 wherein component (a) or component (b) additionally contains a polycarboxylate.

6. A process according to claim 1 wherein the pH of component (b) is higher than the pH of component (a).

7. A process according to claim 6 wherein component (a) does not contain a pH buffer.

8. A process according to claim 6 wherein component (b) does contain a pH buffer.

9. A process according to claim 1 wherein component (b) additionally comprises an effervescent agent.

10. A process according to claim 9claim 9 wherein the effervescent agent is a base or is a peroxide reducing enzyme.

11. A process according to claim 10 wherein the base is a carbonate or a bicarbonate.

12. A process according to claim 10 wherein the surfactant produces a foam upon mixing components (a) and (b).

14. A process according to claim 12 wherein the foam reduces in volume by at least 50% in less than 5 minutes of its generation without any form of physical or chemical intervention.

15. A process according to claim 12 wherein surfactant is a non-ionic surfactant of an HLB of greater than 10.

13. A process according to 12 wherein the foam breaks.

16. A two-compartment dispenser comprising

a first compartment containing an aqueous compositions comprising hydrogen peroxide or an organic peracid and having a pH of greater than 0 but less than 7;

a second compartment containing an aqueous compositions comprising an alkalizing agent and;

dispensing means adapted to dispense the contents (or part thereof) of the compartments on to a surface either sequentially or simultaneously to form a mixture thereof,

characterized in that

components (a) and/or (b) additionally comprise sufficient surfactant, including any super wetting agent, to achieve a surface tension of the combined composition of below 28 mN/m.
