Abstract: This invention provides, amongst other things, a preservative system for aqueous oral care compositions that comprises the addition of one or more quaternary ammonium antimicrobial agents (e.g., cetylpyridinium chloride (CPC)) in combination with comprising benzyl alcohol in a preservative system, can surprisingly allow for the use of relatively less benzyl alcohol while still maintaining antimicrobial efficacy and not adversely affecting the flavor of the composition. The added benefit in using relatively less benzyl alcohol, in addition to lower cost and expense, is also that the flavor or the overall composition is less impacted.
