Mechanism of action of an antiseptic, anti-odor mouthwash.

Inter-related determinants of oral malodor were measured over a three-hour period in 30 human subjects after mouthwash treatments. Re-odoration was important to mouthwash activity for 30 min. At post-treatment times of 60-180 min, the anti-odor activity of the product is due solely to its anti-microbial action.
