Claim:
1. A method for preparing a liquid composition comprising the steps of: a) preparing a first premix composition comprising propylene glycol, an antimicrobial essential oil, and optionally, a flavor; b) preparing a second premix composition comprising propylene glycol, and an organic acid selected from the group consisting of ascorbic acid, sorbic acid, citric acid, glycolic acid, lactic acid and acetic acid, benzoic acid, salicylic acid, phthalic acid, phenolsulphonic acid, succinic acid and mixtures thereof; c) preparing a third premix composition comprising at least one surfactant selected from the group consisting of alkyl sulfates, Poloxamers, and combinations thereof, and an aqueous phase comprising water; and d) adding the first premix to the third premix; e) mixing the composition of step d) until uniform and homogeneous; f) adding the second premix to the composition of step e) and mixing until uniform and homogeneous; and g) adding a sugar alcohol solvent to the composition of step f) and mixing the composition until uniform and homogeneous; wherein the liquid composition resulting from step g) comprises from about 0.001 to about 0.35 w/v % of antimicrobial essential oils, from about 5 to about 15 w/v % of propylene glycol, from about 0.001 to about 1% w/v of flavor, from about 0.001 to about 1.0 w/v % of organic acid, about 2 w/v % or less of total surfactant, and from about 5 to about 15 w/v % of sugar alcohol solvent.
