The invention provides a packaged multiphase dentifrice composition in which an inner first phase is in physical contact with and surrounded by a visually distinct outer second phase, and in which the phases are coextrudable from a single dispensing orifice such that the extrudate has a core of inner first phase and a sheath of outer second phase surrounding the core of inner first phase, characterised in that entrained air or other gas is selectively incorporated into one of the phases, the gas being incorporated as discrete bubbles. |
