Abstract: Gas-free paste or gel dentifrices are made by a process which includes producing a degassed gel of a gelling agent in a polyhydric alcohol, and admixing it with other dentifrice constituents, including powdered light weight polishing agent, under vacuum. Preferably, the powdered polishing agent is degassed in a vacuum hopper, before addition to the gel base in a mixer. Where no vacuum hopper or similar facilities are available, however, powdered polishing agent may be added to the gel in a suitable mixer with adequate head space and any gas present is removed from it by vacuum while it is resting on the surface of the gel, after which the polishing agent is mixed in with the gel.

Abstract: Granular free-flowing non-dusting, spherical enzyme-containing beads for use in detergents are prepared by spraying droplets of a blend consisting essentially of a molten nonionic detergent and an enzyme concentrate from a spray nozzle into cool air in a cooling tower to solidify the droplets and form tiny spherical beads.

Abstract: Post-larval lobsters are raised to a size for marketing in a series of divided trays suitable for stacking and having therein a hollow tube in the center of the trays. Small holes are present on the wall of the hollow tube, the dividers in the trays and the floors of the trays. A pressure pump can be inserted in the hollow tube to aerate the water and to feed the lobsters by pumping air and food from the pump to pass through the holes.

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.

Abstract: Functional speckle particle suitable for use in dentifrice containing allantoin, aluminum dihydroxy allantoinate (ALDA) or aluminum chlorohydroxyallantoinate (ALCA). The speckle is effective in promoting healing of inflamed and bleeding gums or periodontal tissue.

Abstract: A bleaching detergent composition, in which the bleaching component is a water soluble inorganic percompound, such as sodium perborate, includes an alkali metal builder salt, such as pentasodium tripolyphosphate, a water soluble organic builder salt, such as trisodium nitrilotriacetate and an organic detergent, such as sodium linear higher alkyl benzene sulfonate, and is improved in bleaching effectiveness by inclusion therein of a particular concentration of a water soluble copper salt, such as copper sulfate hydrate, which results in the presence of a particular desirable proportion of copper ions in the bleaching detergent solution resulting from normal use of the composition.

Abstract: Oral compositions containing dextranase and a stabilizer/activator selected from the group consisting of manganeous ions, calcium ions, and mixtures thereof.

Abstract: The invention relates to an oral preparation, i.e. dentifrice, which contains non-toxic amino-cyano polymeric diguanide or salt thereof as an anti-bacterial agent.

Abstract: Stable bis-biguanido hexane-containing oral products are disclosed which retain therapeutic activity against plaque and breath odor and concurrently possess desirable foaming properties. The oral products contain polyoxyethylene-polyoxypropylene nonionic surfactant in combination with a foam booster which is a long-chain tertiary amine oxide of C.sub.10 -C.sub.18 chain length or monoethanolamide of a fatty acid having from 10 to 18 carbon atoms.

Abstract: A belt buckle formed of a single piece of hard material having a front face and parallel thereto when the buckle is closed, a back face, connected at an adjacent end of each face by two hinges at the sides of each face and an integral frictional wedged prong connected to the other end of one of said faces, essentially perpendicular thereto, which engages the opposite face in a locking manner.
