METHOD FOR TESTING ORAL MALODOR

摘要

The present invention relates to a method for testing oral malodor, in particular oral malodor from onion and garlic. 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 first sample of exhaled breath from the cleaned oral cavity to provide a first test result representing a first 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 second sample of exhaled breath from the oral cavity to provide a second test result representing a second amount of the at least one oral malodor component detected in the exhaled breath.

1. A method for testing the efficacy of and selecting an oral care composition to reduce oral malodor, wherein the method comprises the steps of:
a1. cleaning at least a part of the oral cavity with an oral care composition and testing the cleaned oral cavity to provide a baseline amount of at least one oral malodor component detected in the exhaled breath; b1. exposing the oral cavity to an oral malodor material containing the at least one oral malodor component; c1. obtaining a first sample of exhaled breath from the oral cavity to detect a first amount of the at least one oral malodor component in the exhaled breath which is a representation of the propylactic effect of the oral care composition; and d1. comparing the first amount of the at least one oral malodor component detected in the exhaled breath after cleansing with an oral care composition with an amount from cleansing with a different oral care composition and selecting the oral care composition with the lower first amount for a method of providing prophylactic effect against at least one malodor component in the oral cavity.
