What is Retsyn®?
The powerful force of Retsyn® makes Certs the mint with "Two-Two-Two Mints in One." But what makes it work on halitosis?

One of the most clever marketing schemes in the world of breath mints was developed for Certs mints, with their introduction in 1960 of the revolutionary, yet scientifically curious, ingredient "Retsyn®", to their mints. What does Retsyn® do? How do its mysterious properties affect bad breath? In the past, you could have visitd the "Center for Extended Retsyn Technology" on the Certs.com web site, but, alas, the Center is no longer available (or was that some clever marketing ruse, as well?).

Fortunately, ordinary citizen Robert Dobrin wondered about Retsyn®, too, and so he wrote to the Warner-Lambert Company (the company that manufactures Certs) and asked them for an explanation. The company's Senior Clinical Scientist for Dental Affairs, Ralph S. Richter, responded. Dobrin published his letter, and Warner-Lambert's response, on his Web site, Corporate Letters. Here's Warner-Lambert's explanation:

Retsyn is a trademark of the Warner-Lambert Company and is the term used to designate the active ingredients in Certs, copper gluconate and hydrogenated cottonseed oil. The hydrogenated oil is an oil-in-water emulsion with the oil droplets reduced to a size of less than 10 microns. This finely micronized oil can, therefore can absorb more odor from the oral cavity than droplets of a larger, more common size. The copper gluconate in Certs acts as a chemical deodorant.

This unique combination of ingredients has been shown in laboratory and clinical studies to effectively neutralize oral malodor for an extended period of time after the mint itself is gone.
