Abstract

The present invention generally relates to processes for cleaning, product kits, and devices using ultrasonic waves.

Claims

1. A method of cleaning and/or removing soil and/or a stain from a surface comprising at least the steps of

(a) contacting said surface with a cleaning composition;

and

(b) concurrent with or subsequent to (a) applying a source of ultrasonic energy to said surface;

where in said cleaning composition has a surface tension sufficient to minimize entrapment of gas during application of ultrasonic energy to the soil.

2. The method according to claim 1 wherein said cleaning composition has a surface tension of from about 15 to about 60 mN/m

3. The method according to claim 1 wherein said source of ultrasonic energy has a frequency of from about 15 kHz to about 200 kHz.

4. The method according to claim 1 wherein said source of ultrasonic energy has an amplitude of from about 10 microns to about 100 microns.

5. The method according to claim 1 wherein said source of ultrasonic energy is hand held.

6. The method according to claim 1 wherein said source of ultrasonic energy has a power of greater than about 10 Watts.

7. The method according to claim 1 wherein said cleaning composition comprises, at least one adjunct ingredient selected from the group consisting of builders, surfactants, enzymes, bleach activators, bleach catalysts, bleach boosters, bleaches, alkalinity sources, antibacterial agent, colorants, perfume, lime soap dispersants, polymeric dye transfer inhibiting agents, crystal growth inhibitors, photobleaches, heavy metal ion sequestrants, anti-tarnishing agents, anti-microbial agents, anti-oxidants, anti-redeposition agents, soil release polymers, electrolytes, pH modifiers, thickeners, abrasives, metal ion salts, enzyme stabilizers, corrosion inhibitors, diamines, suds stabilizing polymers, solvents, process aids, fabric softening agents, optical brighteners, hydrotropes. and mixtures thereof.

8. An ultrasonic cleaning composition, substantially enzyme free, comprising;

(a) an effective amount of a source of hydrogen peroxide;

(b) an effective amount of a surfactant;

(c) an effective amount of a solvent; and

(d) optionally, an effective amount of a stabilizer;

wherein, said composition has a viscosity from about 0.8 cps to about 100,000 cps and said composition minimizes the dissolution of gas under ultrasonic cleaning conditions.

9. An ultrasonic cleaning composition according to claim 8 wherein said composition comprises from about 0.05% to about 15% by weight of composition of said source of hydrogen peroxide.

10. An ultrasonic cleaning composition according to claim 8 wherein said composition comprises from about 1% to about 5% by weight of composition of said source of hydrogen peroxide and the pH of the cleaning composition is greater than about 8.0.

11. An ultrasonic cleaning product comprising:

(i) an ultrasonic cleaning composition, substantially enzyme free, comprising;

(a) an effective amount of a source of hydrogen peroxide;

(b) an effective amount of a surfactant; and

(c) optionally, an effective amount of a stabilizer;

wherein, said composition has a viscosity from about 0.8 cps to about 100,000 cps and said composition minimizes the dissolution of gas under ultrasonic cleaning conditions; and

(ii) an ultrasonic wave generating source for imparting ultrasonic waves.

12. The ultrasonic cleaning product according to claim 11 further comprising instructions for using said product comprising the steps of:

(A) applying an effective amount of said cleaning composition to said surface; and

(B) imparting ultrasonic waves to said surface using said ultrasonic source;

13. The ultrasonic cleaning product according to claim 11 wherein said source of ultrasonic energy has a power of from about 10 Watts to about 75 Watts.

15. The article of manufacture according to claim 14 wherein the instructions for use direct the consumer to apply the cleaning composition to the one or more surfaces prior to and/or during applying ultrasonic energy to the one or more surfaces.

16. An article of manufacture according to claim 14 wherein said source of ultrasonic energy is a hand held device having a power of from about 10 to about 75 watts, and capable of dispensing said cleaning composition.

18. The fabric cleaning composition kit according to claim 17 wherein the source of ultrasonic energy is a hand held and battery powered device, a power of from about 10 to about 75 watts, and capable of dispensing said cleaning composition.

14. An article of manufacture comprising a cleaning composition for cleaning one or more surfaces, and a source of ultrasonic energy, both of which are in a package in association with instructions for use which direct a consumer to apply at least an effective amount of said cleaning composition to provide cleaning for one or more surfaces and wherein, said composition has a viscosity from about 0.8 cps to about 100,000 cps and said composition minimizes the dissolution of gas under ultrasonic cleaning conditions.

17. A surface cleaning composition in kit form, comprising the following components:

a) article of manufacture comprising a pre-treating composition for pre-treating one or more surfaces, and a source of ultrasonic energy, both of which are in a package in association with instructions for use which direct a consumer to apply at least an effective amount of said pre-treating composition to provide pre-treating for one or more surfaces wherein, said pre-treating composition has a viscosity from about 0.8 cps to about 100,000 cps and said pre-treating composition minimizes the dissolution of gas under ultrasonic cleaning conditions;

b) a cleaning composition suitable for cleaning fabrics; and

c) an outer package containing the components a) and b).
