Abstract

Disclosed are oral care mouth rinse compositions formulated as stable oil-in-water emulsions comprising: (a) at least about 0.025% by weight of a quaternary ammonium antimicrobial agent, (b) at least about 0.05% by weight of an essentially water-insoluble volatile oil, and (c) at least about 50% by weight water, wherein the emulsion comprises oil droplets having an average mean particle size of about 350 nm or less. Examples of quaternary ammonium antimicrobial agent include cetylpyridinium chloride (CPC), tetradecylpyridinium chloride, N-tetradecyl-4-ethyl pyridinium chloride or domiphen bromide.

Description

technical field [0001] The present invention relates to mouthwash compositions formulated as oil-in-water emulsions comprising one or more oral care actives and flavor oils. Background technique [0002] Consumers routinely use oral care products such as mouthwashes as part of their oral care hygiene regimen to provide therapeutic, hygiene and cosmetic benefits. Therapeutic benefits include: caries prevention, typically delivered through the use of various fluoride salts; prevention of gingivitis and periodontal disease through the use of antimicrobial agents such as triclosan, stannous fluoride, quaternary ammonium compounds, or essential oils; or Fight allergies by using ingredients like strontium chloride, stannous fluoride, or potassium nitrate. Hygiene and cosmetic benefits include: prevention of plaque and calculus formation, removal and prevention of dental stains, tooth whitening, fresh breath, and general improvement in mouthfeel impression (which can be broadly ch...
