Abstract

The invention relates to degradable chewing gum bases comprising elastomer, polymer resin, filler and further additives, in which the filler portion is entirely or partially replaced by an photoactive filler.

Claims (6)

1. A degradable chewing gum base comprising elastomer, polymer resin, titanium dioxide in the anatase modification in an amount sufficient to promote degradation of the elastomer and the polymer resin, and further additives.

2. The degradable chewing gum base of claim 1 , wherein the the titanium dioxide comprises nano-anatase.

3. The degradable chewing gum base of claim 2 , wherein the proportion of the titanium dioxide is 1 to 20% by weight, based on the total weight of the chewing gum base.

4. The degradable chewing gum base of claim 1 , wherein the proportion of the titanium dioxide is 1 to 20% by weight, based on the total weight of the chewing gum base.

5. The degradable chewing gum base of claim 1 , wherein the proportion of the titanium dioxide is 1 to 20% by weight, based on the total weight of the chewing gum base.

6. A method of producing a degradable chewing gum base of claim 1 , comprising mixing the constituents of the chewing gum base, optionally after an upstream granulation or pulverization step, heating the mixture, and extruding the chewing gum base or casting the chewing gum base in a mold.
