Abstract Flowable powders having up to 60% alcohol content are prepared by the sorption of the alcohol with bulked, low dextrose equivalent dextrins. The resulting products are stable when hermetically packaged and are particularly qualified as alcoholcontaining base materials for oral hygiene powder preparations.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
182 words
A METHOD OF PREPARING A FLOWABLE, DRY-TO-THE-TOUCH, ALCOHOL-CONTAINING MOUTHWASH POWDER WHICH COMPRISES: A. DISSOLVING IN WATER A DEXTRIN HAVING A DEXTROSE EQUIVALENT OF FROM ABOUT 5 TO ABOUT 15; B. EXPANDING THE DEXTRIN BY FORMING A FILM OF THE SOLUTION OF (A) AND DRYING SAID FILM; C. SUBDIVIDING THE DRIED FILM OF DEXTRIN TO YIELD PARTICULATES OF EXPANDED DEXTRIN HAVING A SIZE CORRESPONDING TO A 20-60 MESH SCREEN OPENING (U.S.S. SIEVE), A MOISTURE CONTENT RANGING FROM ABOUT 2 TO ABOUT 6% AND A BULK DENSITY RANGING FROM ABOUT 0.05 TO ABOUT 0.30 GRAMS/CUBIC CENTIMETER; D. CONTACTING THE EXPANDED DEXTRIN OF (C) WITH AN AQUEOUS SOLUTION OF ETHANOL SO AS TO CAUSE THE DEXTRIN TO SORB FROM ABOUT 30 TO ABOUT 60% ETHANOL BY WEIGHT OF THE RESULTING FLOWABLE ETHANOL-CONTAINING POWDER; AND E. BLENDING THE ALCOHOL DEXTRIN OF (D) WITH SMALL BUT EFFECTIVE AMOUNTS OF MOUTHWASH FLAVORING AND COLORING MATERIALS WHEREBY A FLOWABLE POWDERED MOUTHWASH MIXTURE IS PREPARED CONTAINING FROM ABOUT 30 TO ABOUT 60% ETHANOL, SAID MOUTHWASH BEING READILY SOLUBLE IN COLD WATER TO PRODUCE A MOUTHWASH SOLUTION FOR ORAL HYGIENE PURPOSES.

Claim 3
Dependent Claim
24 words
The method of claim 1 wherein the 5-15 D.E. dextrin is expanded by forming a film of the solution and drum drying the film.
Claim 4
Dependent Claim
27 words
The method of claim 1 wherein the 5-15 D.E. dextrin is expanded by forming a film of the solution and drying the film in a spray drier.
Claim 5

Claim 7
Dependent Claim
53 words
The method of claim 1 wherein the dextrin having a dextrose equivalent of from about 5 to about 15 is further characterized by having more than 50% of the trimer, hexamer and heptamer ligomers by weight of its total oligomer (10 or less degree of polymerization) content and less than about 1% glucose.
