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 visibly clear cleansing phase comprising;

at least one surfactant selected from the group consisting of alkyl and alkyl ether sulfates; and

at least one thickener, wherein said thickener is selected from polymeric thickeners; and

b) at least one opaque aqueous benefit phase comprising;

a thickener mixture of a fatty acid and trihydroxystearin;

and at least one benefit agent selected from the group consisting of styling polymers, silicones, crosslinked silicone elastomers, peralkylene hydrocarbons, and hair coloring agents or 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; and

wherein said cleansing phase and said benefit phase form a visible pattern or arrangement that is unchanged for a period of at least about 180 days, when said cleansing phase and said benefit phase sit undisturbed in physical contact with one another at ambient conditions.

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 aid 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.

4. The multi-phase personal care composition of claim 1 wherein aid at least one aqueous benefit phase further comprises at least one surfuctant.

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

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

7. 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.

8. 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 arc 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.

9. 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.

10. The multi-phase personal care composition of claim 1 wherein said surfactant in the cleaning phase further comprises Lauryl Pyrrolidone surfactant.

11. 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.

12. The multi-phase personal care composition of claim 11 further comprising a non-soluble dye in said at least one aqueous benefit phase.

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

14. 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.

15. A method of delivering hair styling benefits to hair, aid method comprising the steps of:

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

b) rinsing aid hair or skin with water.

16. A method of delivering hair coloring benefits to hair, aid method comprising the steps of:

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

b) rinsing aid hair or skin with water.

17. A method of delivering anti-dandruff benefits, aid method comprising the steps of:

a) topically applying an effective amount of a composition according to claim 3 onto hair or skin; and

b) rinsing aid hair or skin with water.

18. A method of delivering volumizing benefits to hair, aid method comprising the steps of:

a) topically applying an effective amount of a composition according to claim 3 onto aid hair; and

b) optionally rinsing aid hair with water.
