A stabilized and extrudable paste or gel dentifrice comprises two dentifrice portions, each of which includes a component which is chemically reactive with the other such component in the other portion, with the portions being maintained separate from each other in a dispensing container from which they are dispensable together through a closable opening therein in response to pressure. One of the reactive compounds may be an alkali metal fluorine-containing salt such as sodium fluoride or sodium monofluorophosphate, used for its effect in hardening tooth enamel, and the other may be a water insoluble calcium salt, such as dicalcium phosphate, tricalcium phosphate or calcium carbonate, used as a polishing agent. To improve storage stability of the dentifrice such dentifrice portions are separated by an extrudable material, such as a polyhydric alcohol-water gel of a gum, e.g., sodium carboxymethyl cellulose. Also within the invention are various methods for the manufacture of the mentioned dentifrices.

A dispensing container of stabilized, extrudable cream, paste or gel dentifrice comprising at least two components which are normally reactive with each other and which are maintained separate from each other in the dispensing container during normal repeated uses of the dentifrice, which container

A dispensing container of stabilized, extrudable cream, paste or gel dentifrice comprising at least two components which are normally reactive with each other and which are maintained separate from each other in the dispensing container during normal repeated uses of the dentifrice, which container is of a deformable or collapsible tube type, having a closable opening through which the dentifrice is pressure dispensable in response to squeezings of the tube, with the normally reactive components being dispensed together during initial and subsequent dispensings, and in which said components are maintained separate from each other until each dispensing or until shortly before such dispensings by a barrier of extrudable separating material between them, which separating material remains at least in part between the reactive dentifrice components remaining in the container after repeated dispensings and is extrudable through the dispensing opening of the dispensing container together with and as a part of at least some of the dentifrice being dispensed in response to squeezing of the tube.
