Abstract

A laundry detergent system comprising a highly concentrated liquid laundry detergent and a device connected to a water supply feed, that provides the injection pressure of the detergent composition being greater than water flow pressure at the junction of the detergent composition and the water flow and water flow rate at the junction of greater than 0.25 m/sec; wherein the flow rate ratio of the detergent composition to the water flow is in the range of from about 0.0001 to about 0.5.

Claims

1. A laundry detergent system comprising:

(a) a highly concentrated liquid laundry detergent composition comprising;

(a1) a surfactant, selected from anionic, nonionic, cationic surfactants and mixtures thereof in an amount of from about 50% to about 100%, by weight of the composition; and

(a2) a solvent in an amount of from about 0% to about 10%; and

(b) a device connected to a water supply feed, that provides the injection pressure of the detergent composition being greater than water flow pressure at the junction of the detergent composition and the water flow and water flow rate at the junction of greater than 0.25 m/sec;

(c) wherein the flow rate ratio of the detergent composition to the water flow is in the range of from about 0.0001 to about 0.5.

2. The system of claim 1 wherein the device comprises a reducer installed along the water supply feed.

3. The device of claim 2 wherein the ratio of the internal diameters of the entrance and exit the reducer is greater than 1.65.

4. The device of claim 2 wherein the ratio of the internal diameter of a water supply feed hose to the internal exit diameter of the reducer is greater than 1.65.

5. The device of claim 2 wherein the reducer is a Venturi tube.

6. The system of claim 1 wherein the device comprises a pump.

7. The system of claim 1 wherein the water content of the composition is less than 30%.

8. The system of claim 1 wherein the composition contains functional ingredients selected from a group comprises of enzyme, fluorescent dye, builder, buffering agent, anti-redeposition agent, soil release polymer, dye, fragrance, and bleach system.

9. The system of claim 1 wherein the device comprises an intermediate dosing chamber.

10. The system of claim 1 wherein the system is connected to another system comprising a reducer and a laundry booster composition.

11. The system of claim 10 wherein the laundry booster composition is an aqueous product containing ingredients selected from the group consisting of surfactant, enzyme, fluorescent dye, builder, buffering agent, anti-redeposition agent, soil release polymer, dye, fragrance, bleach system and mixtures thereof.

12. The system of claim 11 wherein the booster and the concentrated liquid detergent dose sequentially.
