New Chewing Gum Base Prevents Adhesion To Concrete Sidewalks, Cleans Up More Easily

April 1, 2014: 12:00 AM EST
Wrigley has developed a chewing gum base using block, rather than linear, polymers that are much easier to clean from environmental surfaces. Also known as copolymers, the new base ingredients provide appropriate elasticity for chewing but prevent adhesion to rough surfaces like concrete sidewalks. It costs a lot of money to properly clean sidewalks of so-called chewing gum “cud” that has not been properly disposed of. But Wrigley’s invention, for which the company is seeking a patent, allows the cud to be removed with standard high pressure water washing in 20 seconds with minimal residue.
