Abstract
An antimicrobial mouthwash composition that is useful in the prevention and reduction of bad breath, plaque and related gum diseases comprises an antimicrobial effective amount of thymol and one or more other active essential oils; optionally, ethanol in an amount up to about 30% v/v; from about 0.1% to about 8.0% w/v of a peroxide; at least one surfactant in an amount sufficient to solubilize the essential oils; and water. The compositions may be reduced alcohol or alcohol-free compositions. Further a two-part mouthwash system is disclosed, comprising a base composition and a peroxide solution which may be mixed to form an antimicrobial mouthwash composition. The actives not only provide enhanced efficacy but are completely solubilized, thus providing an aesthetically appealing product.
