Which of the following is NOT an example of a wetting agent?

Explanation:
Wetting agents reduce surface tension so a liquid can spread over a solid surface, improving wetting and dissolution. Surfactants are the classic example of wetting agents. Glycerin and alcohol can also enhance wetting in formulations by acting as co-solvents and lowering interfacial tension. Flavorings, however, are added for taste or aroma and do not function to modify wetting properties in a reliable way, so they are not considered wetting agents.
