Multi-phase personal care compositions comprising: (a) at least one personal care composition phase; and (b) at least one another personal care composition phase; wherein the phase (a) and said the phase (b) are visually distinct phases that are packaged in physical contact, wherein the phase (a) and the phase (b) have a yield stress of from about IPa to about 100Pa, and wherein the viscosity ratio of the phase (a) to the phase (b) is from about 1 : 15 to about 15: 1 at shear stress over the yield stress of the phases (a) and (b) up to at least 200 Pa. By matching rheology profiles of each phase compositions in such kinetic conditions, desired patterns of multi-phase personal care compositions are easily obtained and/or maintained for a longer period of time. |
