Retsyn
From Free net encyclopedia
Retsyn is a Warner-Lambert Company trademark for the active ingredient in Certs, Cool Mint Drops, and Certs Power Mints. Retsyn consists of a combination of copper gluconate and partially hydrogenated cottonseed oil.
According to a Pfizer FAQ Page, it is Retsyn, in addition to the flavor, which is responsible for the efficacy of Certs against breath odors. The hydrogenated vegetable oil and the copper gluconate absorb odors in the mouth.
The copper gluconate gives Retsyn its green color.
