Abstract: Compositions in the form of an oil-in-water emulsion composition include an oil phase that includes one or more flavorants; and a continuous aqueous phase that includes water, one or more preservatives, one or more emulsifying agents, and optionally one or more emulsifier adjuvants; wherein the preservative includes a hop acid and/or a salt thereof.

Abstract: Compositions in the form of an oil-in-water emulsion composition include an oil phase that includes a flavorant, and optionally an emulsifier adjuvant; and a continuous aqueous phase that includes water, an emulsifier adjuvant and an emulsifying agent, wherein the oil-in-water emulsion composition is substantially free of weighting agents and/or gum acacia.

Abstract: Compositions in the form of an oil-in-water emulsion composition include an oil phase that includes a flavorant; and a continuous aqueous phase that includes water, a preservative, and an emulsifying agent, and optionally an emulsifier adjuvant; wherein the preservative includes one or more vitamins and/or salts thereof.

Abstract: Compositions in the form of an oil-in-water emulsion composition include an oil phase that includes a flavorant; and a continuous aqueous phase that includes water, a preservative and a phospholipid emulsifying agent, and optionally an emulsifier adjuvant; wherein the phospholipid emulsifying agent includes a low content of primary ammonium functional groups.

Abstract: An ink for use in combination with an ink-jet printer comprises a mixture including a colorant, a liquid vehicle comprising 1,6-hexanediol and 1,5-pentanediol in a ratio in the range of 1:4 (wt/wt) to 4:1 (wt/wt), and/or an amount of imidazole in the range of 0.1 wt % to 6 wt %, and potentially provides at least one of the following enhancements to the ink improved print quality, increased decap time, pen reliability, environmental robustness of ink in pen, environmental robustness of printed ink on media, and aid in maintaining the pH of the ink in a desired range.
