Abstract

Personal care compositions comprising a cleansing phase and a benefit phase. These products are intended to provide a multi-phase personal care composition that is packaged in physical contact while remaining stable and providing improved in-use and after-use hair and skin benefits.

Claims

1. A multi-phase personal care composition comprising:

a) at least one cleansing phase comprising at least one surfactant and at least one thickener; and

b) at least one aqueous benefit phase comprising at least one thickener and at least one benefit agent selected from the group consisting of styling polymers, silicones, crosslinked silicone elastomers, peralkylene hydrocarbons, and hair coloring agents/dyes;

wherein said at least one cleansing phase and said at least one benefit phase are visually distinct phases that are packaged in physical contact with one another.

2. The multi-phase personal care composition of claim 1 wherein said surfactant is selected from the group consisting of anionic surfactants, nonionic surfactants, zwitterionic surfactants, amphoteric surfactants, soap, and mixtures thereof.

3. The multi-phase personal care composition of claim 1 wherein said at least one cleansing phase comprises a thickener selected from the group consisting of inorganic water thickeners, polymeric thickeners, additives that promote thickening via lamellar structuring of surfactants, organic crystalline thickeners, and mixtures thereof.

4. The multi-phase personal care composition of claim 1 wherein said at least one aqueous benefit phase comprises a thickener selected from the group consisting of additives that promote thickening via lamellar structuring of surfactants, organic crystalline thickeners, inorganic water thickeners, polymeric thickeners, and mixtures thereof.

5. The multi-phase personal care composition of claim 1 wherein said at least one aqueous benefit phase further comprises at least one benefit agent selected from the group consisting of anti-dandruff actives, humectants, water soluble nonionic polymers, cationic polymers, conditioning agents, and particles.

6. The multi-phase personal care composition of claim 1 wherein said at least one cleansing phase further comprises at least one benefit agent selected from the group consisting of anti-dandruff actives, styling polymers, silicones, crosslinked silicone elastomers, peralkylene hydrocarbons, hair coloring agents/dyes, humectants, water soluble nonionic polymers, cationic polymers, conditioning agents, and particles.

7. The multi-phase personal care composition of claim 1 wherein said at least one aqueous benefit phase further comprises at least one surfactant.

8. The multi-phase personal care composition of claim 7 wherein said surfactant is selected from the group consisting of anionic surfactants, nonionic surfactants, zwitterionic surfactants, amphoteric surfactants, and mixtures thereof.

9. The multi-phase personal care composition of claim 1 wherein a visible pattern or arrangement of the visually distinct phases is substantially unchanged for a period of at least about 180 days, when said at least one cleansing phase and said at least one aqueous benefit phase are sitting undisturbed in physical contact with one another at ambient conditions.

10. The multi-phase personal care composition of claim 1 wherein said at least one cleaning phase and said at least one aqueous benefit phase are visually distinct phases due to inclusion of a colorant in said at least one cleansing phase, in said at least one aqueous benefit phase, and/or in both of said at least one cleansing phase and said at least one aqueous benefit phase.

11. The multi-phase personal care composition of claim 1 wherein said at least one cleansing phase, said at least one aqueous benefit phase, or both said at least one cleansing phase and said at least one aqueous benefit phase are visibly clear.

12. The multi-phase personal care composition of claim 1 wherein one of said at least one cleansing phase and said at least one aqueous benefit phase is visibly clear and the other of said at least one cleansing phase and said at least one aqueous benefit phase is opaque.

13. The multi-phase personal care composition of claim 1 wherein said visually distinct phases form a pattern selected from group consisting of striped, geometric, marbled, and combinations thereof.

14. The multi-phase personal care composition of claim 1 wherein the density difference between said at least one cleansing phase and said at least one aqueous benefit phase is less than about 0.30 g/cm³.

15. The multi-phase personal care composition of claim 1 wherein the density difference between said at least one cleansing phase and said at least one aqueous benefit phase is less than about 0.05 g/cm³.

16. The multi-phase personal care composition of claim 1 wherein the viscosity of said at least one cleansing phase and said at least one aqueous benefit phase are in the range of from about 10,000 to about 200,000,000 centipoise at stress measurements of from about 1 to about 20 pascals at about 25°

C.

17. The multi-phase personal care composition of claim 1 wherein the viscosity of said at least one cleansing phase and said at least one aqueous benefit phase are in the range of from about 100,000 to about 100,000,000 centipoise at stress measurements of from about 1 to about 20 pascals at about 25°

C.

18. The multi-phase personal care composition of claim 1 wherein said surfactant is a surfadone surfactant.

19. The multi-phase personal care composition of claim 1 further comprising a water-soluble dye in said at least one cleansing phase and/or said at least one aqueous benefit phase.

20. The multi-phase personal care composition of claim 19 further comprising a non-soluble dye in said at least one aqueous benefit phase.

21. The multi-phase personal care composition of claim 1 further comprising a non-soluble dye in said at least one aqueous benefit phase.

22. A method of delivering conditioning benefits to hair or skin, said method comprising the steps of:

a) topically applying an effective amount of a composition according to claim 1 onto said hair or skin; and

b) optionally rinsing said hair or skin with water.

23. A method of delivering hair styling benefits to hair, said method comprising the steps of:

a) topically applying an effective amount of a composition according to claim 1 onto hair; and

b) rinsing said hair or skin with water.

24. A method of delivering hair coloring benefits to hair, said method comprising the steps of:

a) topically applying an effective amount of a composition according to claim 1 onto said hair; and

b) rinsing said hair or skin with water.

25. A method of delivering anti-dandruff benefits, said method comprising the steps of:
