Abstract

The present invention relates to a personal care article that comprises a single chamber package and a liquid personal care product. The package comprises a dispensing orifice, a first zone proximate to the dispensing orifice and a second zone distal to the dispensing orifice. The liquid personal care product comprises a first personal care composition substantially disposed within the first zone and the second personal care composition substantially disposed within the second zone. The first composition comprises a first fragrance character and the second composition comprises a second fragrance character; wherein the first fragrance character is distinct from the second fragrance character.

Claims

1. ) A personal care article for dispensing and or applying a liquid personal care product comprising:

a) a single chamber package comprising a dispensing orifice, a first zone proximate to said dispensing orifice and a second zone distal to said dispensing orifice; and

b) a liquid personal care product comprising a first personal care composition substantially disposed in said first zone and a second personal care composition substantially disposed in said second zone;

wherein said first composition comprises a first fragrance character;

wherein said second composition comprises a second fragrance character; and

wherein said first fragrance character is distinct from said second fragrance character.

2. ) The personal care article of claim 1 wherein said first zone comprises from about 10% to about 90%, by volume, of said package.

3. ) The personal care article of claim 1 wherein said first zone comprises from about 30% to about 70%, by volume of said package.

4. ) The personal care article of claim 1 wherein said first zone comprises about 50%, by volume of said package.

5. ) The personal care article of claim 1, wherein said first personal care composition comprises a first concentration of surfactant and said second personal care composition comprises a second concentration of surfactant.

6. ) The personal care article of claim 1, wherein said first concentration of surfactant is greater than said second concentration of surfactant.

7. ) The personal care article of claim 1, wherein said first personal care composition comprises a first partitioned perfume component.

8. ) The personal care article of claim 7, wherein said first partitioned perfume component has a C log P of at least 2.

9. ) The personal care article of claim 7, wherein said first partitioned perfume component has a molar volume of from about 100 Angstrom to about 300 cm³.

10. ) The personal care article of claim 7, wherein said first partitioned perfume component has a diffusion coefficient of less than 5.3×

10<sup>−

12</sup> according to the restricted diffusion analytical solution.

11. ) The personal care article of claim 7, wherein said first partitioned perfume has a C log P, Molar Volume, and the system has a Zero-shear viscosity such that:

12. ) The personal care article of claim 1, wherein said second personal care composition comprises a second partitioned perfume component.

13. ) The personal care article of claim 12, wherein said second partitioned perfume component has a C log P of at least 2.

14. ) The personal care article of claim 12, wherein said second partitioned perfume component has a molar volume of from about 100 Angstrom to about 300 cm³.

15. ) The personal care article of claim 12, wherein said second partitioned perfume component has a diffusion coefficient less than 5.3×

10<sup>−

12</sup> according to the restricted diffusion analytical solution.

16. ) The personal care article of claim 12, wherein said first partitioned perfume has a C log P, Molar Volume, and the system has a Zero-shear viscosity such that:

17. ) The personal care article of claim 1, wherein said first personal care composition comprises a micellar phase.

18. ) The personal care article of claim 1, wherein said second personal care composition comprises a micellar phase.

19. ) The personal care article of claim 1, wherein said first personal care composition comprises a lamellar phase.

20. ) The personal care article of claim 1, wherein said second personal care composition comprises a lamellar phase.

21. ) The personal care article of claim 1 wherein said first personal care composition has a zero-shear viscosity is at least 500 Pascal.

22. ) The personal care article of claim 1 wherein said second personal care composition has a zero-shear viscosity is at least 500 Pascal.

23. ) The personal care article of claim 1, wherein said first personal care composition is substantially dispensed prior to dispensing said second personal care composition.

24. ) The personal care article of claim 1 wherein said first personal care composition is a distinct hue from said second personal care composition.

25. ) The personal care article of claim 1, wherein said first zone is in physical contact with said second zone within said package.

26. ) The personal care article of claim 1, further comprises a third zone which is medial to the dispensing orifice.

27. ) The personal care article of claim 26 further comprising a third personal care composition substantially disposed within said third zone;

said third personal care composition comprising a third fragrance character wherein said third is distinct from said first fragrance character and said second fragrance character.
