ABSTRACT:
Dentifrice speckles of substantially uniform shape and size are made by agitating the material of such speckles (binder plus dentifrice component) in a liquid dispersing medium at a temperature at which the binder is liquid but undissolved and unemulsified in the dispersing medium, and cooling the dispersion to a temperature below the solidification point of the speckling material so as to solidify it into speckles of desired size. Such speckles may be separated from the dispersing medium or may remain in it and be utilized with it. Preferably the speckles are incorporated in dentifrices and contain dentifrice components desirably maintained separate from the rest of the dentifrice. Also included within the invention described are the speckles and dentifrices containing them.
