Abstract
Abstract A new chewing gum is provided, which does not adhere to dentures formed from conventional denture materials, aids in reducing and/or substantially eliminating denture odor, and is formed from a synthetic gum base material which contains titanium dioxide, various detackifying agents, viscosity modifying agents and wetting agents, and a soluble phase which includes one or more sweeteners, wetting agents, flavoring materials, coloring, and optionally chlorophyllin or other breath freshener.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
158 words
A chewing gum composition which will not adhere to artificial teeth, dentures and plastic filling material while substantially reducing denture odor, comprising a gum base comprising one or more elastomers; one or more hard waxes having a melting point above about 65°C, and which provide lubricity and slip properties to the gum base; one or more solvents for the elastomers, which have minimal tackifying properties; one or more hydrophilic-type detackifiers which absorb saliva and become slippery and are incompatible with the elastomer and solvent for the elastomer; one or more texturizing agents; one or more softening agents having a melting point above about 22°C; one or more emulsifiers which function as slip agents and impart hydrophilic properties to the gum base making same slippery on contact with saliva; and titanium dioxide in an amount within the range of from about 0.3 to about 1% by weight of the gum base, and a soluble phase comprising flavor and sweeteners.
Claim 2
Dependent Claim
158 words
A chewing gum composition which will not adhere to artificial teeth, dentures and plastic filling material while substantially reducing denture odor, comprising a gum base comprising one or more elastomers; one or more hard waxes having a melting point above about 65°C, and which provide lubricity and slip properties to the gum base; one or more solvents for the elastomers, which have minimal tackifying properties; one or more hydrophilic-type detackifiers which absorb saliva and become slippery and are incompatible with the elastomer and solvent for the elastomer; one or more texturizing agents; one or more softening agents having a melting point above about 22°C; one or more emulsifiers which function as slip agents and impart hydrophilic properties to the gum base making same slippery on contact with saliva; and titanium dioxide in an amount within the range of from about 0.3 to about 1% by weight of the gum base, and a soluble phase comprising flavor and sweeteners.

Dependent Claim
34 words
The chewing gum composition as defined in claim 2 wherein said hard waxes are employed in an amount within the range of from about 12 to about 25% by weight of the gum base.
Claim 7
Dependent Claim
36 words
The chewing gum composition as defined in claim 2 wherein said solvent for the elastomers is employed in an amount within the range of from about 15 to about 35% by weight of the gum base.
Claim 8
Dependent Claim
34 words
The chewing gum composition as defined in claim 2 wherein the hydrophilic-type detackifier is employed in an amount within the range of from about 15 to about 30% by weight of the gum base.
Claim 9
Dependent Claim
38 words
The chewing gum composition as defined in claim 2 wherein the texturizing agent comprises calcium carbonate or talc employed in an amount within the range of from about 8 to about 50% by weight of the gum base.
