Alcohol: How an inactive ingredient delivers the active ingredients

LISTERINE® Antiseptic’s alcohol-containing products use only pharmacopoeial (USP) grade alcohol. Even though alcohol is an inactive ingredient, it plays two very important roles that contribute to the effectiveness of LISTERINE^® Antiseptic rinses:

• Alcohol acts as a solvent to help solubilize the ingredients
• Alcohol also acts as a vehicle for delivering the active ingredients
• Alcohol enables the 3 Essential Oils to penetrate the plaque biofilm or bacterial communities
