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
