Abstract
Abstract A non-alcoholic effervescent compound for cleaning and disinfecting the mouth, teeth, gums and breath without necessity of alcohol as a solvent. Surface acting agents, or surfactants, are used to reduce surface tension of the compound in solution, facilitating dissolution of all additives including non-soluble oil-containing components. Surface acting agents also produce a foaming effect which loosens bacteria and food off and out from between teeth. The compound eliminates use of alcohol as a solvent, has increased cleaning action from both foaming and effervescence and produces a good-tasting, desirable mouthwash with appropriate flavor concentrations.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
A dry non-alcoholic mouthwash compound in tablet or in dry granular form adapted to be dissolved in water for cleaning and disinfecting an individual's mouth, teeth, gums and breath, comprising: (a) at least one solid, pharmaceutically acceptable acid and at least one solid, pharmaceutically acceptable base, which are adapted to react to produce carbon dioxide when dissolved in water causing effervescence; (b) about 38% by weight of at least one additive consisting of a volatile oil in spray-dried form for use as a flavoring agent; (c) an effective amount of one or more of the following surface acting agents selected from a group consisting essentially of sodium laurylsulfate, sodium n-laurylsarcosinate, sodium alkylsulfoacetate, sulfocolaurate, sulfated monoglyceride, and sodium monoglyceride, the surface acting agent acting as a solvent in water to reduce surface tension between the additive and the water, to disperse the flavoring agent, and to render the use of alcohol in the mouthwash unnecessary.

Claim 8
Independent Claim
63 words
A method for cleaning the oral cavity, comprising placing an aqueous solution of an effervescing couple, a quantity of about 38% by weight of spray dried volatile oil used as a flavoring agent, and one or more surface acting agents into the mouth and causing the surface acting agents to foam and disperse the flavoring agent by agitation of solution in the mouth.
Claim 9
Independent Claim
63 words
A method for cleaning the oral cavity, comprising placing an aqueous solution of an effervescing couple, a quantity of about 38% by weight of spray dried volatile oil used as a flavoring agent, and one or more surface acting agents into the mouth and causing the surface acting agents to foam and disperse the flavoring agent by agitation of solution in the mouth.
