Two phase toothpaste composition

An oral care kit, comprising:

• (a) a first chamber having a first outlet in fluid communication with said first chamber for discharge of a first dentifrice from said first chamber;
• and
• (b) a second chamber having a second outlet in fluid communication with said second chamber for discharge of a second dentifrice from said second chamber;
• (c) wherein said first dentifrice comprises a safe and effective amount of a halogenated diphenyl ether in a first orally acceptable aqueous vehicle, said second dentifrice comprises a safe and effective amount of a stannous salt in a second orally acceptable aqueous vehicle, said second dentifrice comprises no less than 10 molar percent of soluble stannous ion respective to a mathematical sum of moles of said soluble stannous ion and moles of said stannous salt in said second dentifrice, and said second outlet is proximate to said first outlet so that, during simultaneous discharge of said first dentifrice from said first chamber through said first outlet and of said second dentifrice from said second chamber through said second outlet, discharged first dentifrice fluidly interfaces with discharged second dentifrice to yield an amalgam such that said first dentifrice provides at least one first portion of said amalgam, said second dentifrice provides at least one second portion of said amalgam, and at least one said first portion is in fluid interface with at least one said second portion.
