Abstract

A foam-generating kit contains a non-aerosol container with a foam-generating dispenser and a high surfactant composition, preferably within the container. The high surfactant composition comprises, by weight of the high surfactant composition, at least 20% of a surfactant system. When the foam-generating dispenser is employed with the high surfactant composition, the foam-generating dispenser generates a foam having a foam to weight ratio of greater than about 2 mL/g.

Claims (16)

1. A foam-generating kit comprising:

A. a non-aerosol container comprising a foam-generating dispenser for generating a foam, wherein the foam-generating dispenser includes a gas imparting mechanism to form the foam from air via an air injection piston, foam-generating aperture, an impinging surface, a mesh or net, a pump, an additional mesh and/or sponge located slightly within, and/or at the tip of the nozzle of said container, and a sprayer; and

B. a high surfactant dishwashing composition comprising, by weight of the high surfactant dishwashing composition, from 47.4% to about 99% of a surfactant system, said dishwashing composition comprising at least one of a microemulsion and a protomicroemulsion,

wherein when employed with the high surfactant dishwashing composition, the foam-generating dispenser generates a foam having a foam to weight ratio of greater than about 2 mL/g.

2. The foam-generating kit according to claim 1 , wherein said surfactant system comprises from about 54% to about 99% of the high surfactant dishwashing composition, by weight.

3. The foam-generating kit according to claim 1 , wherein the foam-generating dispenser comprises at least three meshes, wherein the high surfactant dishwashing composition flows through the three meshes in series so as to generate the foam.

4. The foam-generating kit according to claim 1 , wherein the high surfactant dishwashing composition is a Newtonian Fluid.

5. The foam-generating kit according to claim 1 , wherein the high surfactant dishwashing composition further comprises an enzyme.

6. The foam-generating kit according to claim 1 , further comprising a shaped applicator.

7. The foam-generating kit according to claim 1 wherein the high surfactant composition comprises non-visible droplets of oil.

8. The foam-generating kit of claim 1 , wherein the non-aerosol container is a single compartment container.

9. A foam-generating kit according to claim 1 wherein said high surfactant dishwashing composition is in the form of a microemulsion.

10. A foam-generating kit according to claim 1 wherein said high surfactant dishwashing composition is in the form of a protomicroemulsion.

11. A foam-generating kit according to claim 7 wherein said non-visible droplets of oil have a maximum diameter of less than about 100 angstroms as measured by ISO method 7027.

12. The foam-generating kit according to claim 1 wherein the microemulsion or protomicroemulsion comprises a low water-soluble oil having a solubility in water of less than about 5,000 ppm.

13. The foam-generating kit according to claim 12 wherein the low water-soluble oil is selected from the group consisting of: terpenes, isoparaffins, and mixtures thereof.
