When the body is exposed to ethanol it is metabolised, and the compound acetaldehyde is produced.1Acetaldehyde has been identified as a carcinogen, and occurs naturally in many foods.2

In general terms, the level of carcinogenic risk for any carcinogen is dependent on level of exposure in terms of quantity to which the subject is exposed and the duration of exposure.

Exposure to acetaldehyde from dietary sources and mouth rinses: men3,4

From the above graphs, two rinses of an alcohol-containing mouth rinse expose an individual to minimal acetaldehyde compared to commonly consumed foodstuffs.3,4

The exposure of an individual to acetaldehyde is also affected by lifestyle factors such as consuming alcoholic drinks5,6 and smoking,7 both of which may increase exposure.
