Abstract

A method of visualizing the cleaning performance of a cleaning composition is provided.

Claims

1. A method of visualizing the cleaning performance of a cleaning composition, said method comprising the steps of:

(a) providing an oil medium, a water medium and an oil-water interface;

(b) adding an effective amount of the cleaning composition to the oil medium; and

(c) observing the cleaning composition travelling along the oil medium to break out the oil-water interface.

2. A method according to claim 1 wherein the oil medium is present as an island surrounded by the water medium or an island floating on the water medium.

3. A method according to claim 1 wherein the oil medium has a substantially circular shape.

4. A method according to claim 1 further comprising the step of quantifying the speed of cleaning by measuring the time taken for the composition to break out the oil-water interface.

5. A method according to claim 1 wherein the oil is a vegetable oil, preferably selected from the group consisting of:

sesame oil, canola oil, olive oil, rapeseed oil, coconut oil, corn oil, peanut oil, sunflower oil, and mixtures thereof.

6. A method according to claim 1 wherein the oil is a cooked oil.

7. A method according to claim 1 wherein the water medium and/or the oil medium are colored.

8. A method according to claim 1 wherein the weight ratio of the oil medium to the cleaning composition is from about 30 to about 50.

9. A method according to claim 1 wherein the water medium comprises a rheology modifier.

10. A method according to claim 1 wherein the oil medium is present as an island surrounded by the water medium or an island floating on the water medium wherein the oil island is created by placing a first container, having side walls, upside down on a second container, having side walls, wherein the first container has an aperture to allow the feeding of the oil, the side walls of the first and second container defining a moat and wherein the moat is filled with water and wherein the first container is subsequently removed.

11. A method according to claim 1 wherein the oil medium is present as an island surrounded by the water medium or an island floating on the water medium wherein the oil island is created by providing a water medium comprising water and a rheology modifier and adding oil to the water medium.

12. A cleaning composition having a break-out time of less than 60 seconds according to the method of claim 1 wherein the oil medium is present as an island surrounded by the water medium or an island floating on the water medium wherein the oil island is created by placing a first container, having side walls, upside down on a second container, having side walls, wherein the first container has an aperture to allow the feeding of the oil, the side walls of the first and second container defining a moat and wherein the moat is filled with water and wherein the first container is subsequently removed wherein the first container has a diameter of about 55 mm and is filled with about 2 ml of olive oil and the second container has a diameter of about 90 mm and is filled with about 12 ml of distilled water and about 50 μ

l of the cleaning composition are delivered to the centre of the oil medium.

13. A cleaning composition having a break-out time of the oil-water interface according to the method of claim 1 of less than 100 seconds, wherein the oil medium is present as an island surrounded by the water medium or an island floating on the water medium wherein the oil island is created by providing a water medium comprising water and a rheology modifier and adding oil to the water medium and wherein the water medium is about 35 g of water containing about 0.15%, by weight of the water medium, of xhanthan gum and about 2.5 g of oil are delivered onto the water medium and a drop of the cleaning composition is delivered to the centre of the oil medium, wherein the break-out time is the average break-out time using three different oil media comprising:

(a) an uncooked blend of corn oil, sunflower oil and peanut oil where the three different oil media are in equal amount, (b) olive oil, (c) and baked blend of corn oil, sunflower oil and peanut oil, where the three oils are in equal amount.

14. The method according to claim 1 further comprising the step of advertising the cleaning performance of a cleaning composition.
