    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.

    Abstract: An in vitro method for determining the bioavailability of zinc (II) ions from an oral care composition comprises: providing a sample comprising, the oral care composition; contacting the sample with a biorelevant substrate, separating the biorelevant substrate from the sample., contacting the biorelevant substrate with an indicator under conditions selected such that the indicator is capable of reacting with zinc (II) ions, and determining a light absorbance of the indicator. The indicator is zincon or a salt thereof. The method is useful for estimating the ability of an oral care composition to deliver therapeutically-active zinc (II) ions to the oral cavity. Also provided is the use of zincon and a biorelevant substrate in vitro to determine the bioavailability of zinc (II) ions from an oral care composition comprising, a zinc source.
