Dentyl pH is a brand of mouthwash, an oral hygiene product designed to reduce the presence of bacteria responsible for tooth decay, gingivitis and halitosis. Traditional mouthwash formulations use alcohol or other antimicrobial ingredients to kill bacteria. Although Dentyl pH contains anti-bacterial agents (cetylpyridinium chloride, triclosan), it is atypical in that it also contains isopropyl myristate, an oily, non-aqueous, component that adheres to bacteria making them easier to rinse from the mouth. As of 2007, Dentyl pH was one of the top two mouthwash brands in the United Kingdom.
