Abstract

The present invention relates to a method for testing oral malodor, in particular oral malodor from coffee. Described herein are methods for testing the efficacy of an oral care composition to reduce oral malodor, the method comprising the steps of: a) cleaning at least a part of the oral cavity with an oral care composition; b) testing a sample of exhaled breath from the cleaned oral cavity to provide a test result representing a amount of at least one oral malodor component detected in the exhaled breath; c) exposing the oral cavity to an oral malodor material including or capable of forming the at least one oral malodor component; and d) testing a sample of exhaled breath from the oral cavity to provide a test result representing an amount of the at least one oral malodor component detected in the exhaled breath.
