The present invention relates a dentifrice formulation contained in physically separated compartments of a dispenser, comprising a first dentifrice composition having an ionic strength of from about 1,000 .mu. mho to about 50,000 .mu. mho comprisi ng from about 0.1% to about 8% of a polyoxyethylene having a molecular weight of from ab out 200,000 to about 7,000,000 and from about 92% to about 99.5% of one or more aque ous carriers; and a second dentifrice composition. The present invention also relate s to a dentifrice formulation contained in physically separated compartments of a dispe nsers, comprising a first dentifrice composition having an ionic strength of from about 1,000 .mu. mho to about 50,000 .mu. mho: and a second dentifrice composition comprising fro m about 0.1% to about 8% of a polyoxyethylene having a molecular weight of from about 200,000 to about 7,000,000 and from about 92% to about 99.9% of one or more aque ous carriers. The present invention also relates to a dentifrice composition having an ionic strength of from about 1,000 .mu. mho to about 50,000 .mu. mho comprising from a bout 0.1% to about 8% of a polyoxyethylene having a molecular weight of from about 200,000 to about 7,000,000 and from about 92% to about 99.9% of one or more aqueous carrier s.
