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.
Claims20
An oil-in-water emulsion composition comprising:
- an oil phase comprising:
- about 0.01 wt. % to about 30 wt. %, based on a total weight of the emulsion composition, of a flavorant;
- and
- optionally about 0.01 wt. % to about 10 wt. %, based on a total weight of the emulsion composition, of an emulsifier adjuvant;
- and
- a continuous aqueous phase comprising:
- water;
- about 0.01 wt. % to about 30 wt. %, based on a total weight of the emulsion composition, of a preservative;
- and
- about 0.01 wt. % to about 10 wt. %, based on a total weight of the emulsion composition, of a phospholipid emulsifying agent, wherein the phospholipid emulsifying agent comprises from about 0.001 mmol to about 1.0 mmol of primary ammonium functional group per gram of the phospholipid emulsifying agent.
A method comprising:
- providing an oil phase comprising a flavorant and optionally an emulsifier adjuvant;
- providing an aqueous phase comprising water, a preservative, a phospholipid emulsifying agent, and optionally an emulsifier adjuvant;
- mixing the oil phase and the aqueous phase to obtain a pre-emulsion;
- and
- homogenizing the pre-emulsion to obtain an oil-in-water emulsion;
- wherein the phospholipid emulsifying agent comprises about 0.001 to about 1.0 mmol of primary ammonium functional group per gram of the phospholipid emulsifying agent;
- optionally wherein the homogenizing comprises a multi-stage homogenization process.
A method for stabilizing a foam composition, the method comprising adding to the foam composition an oil-in-water emulsion comprising from about 0.01 wt. % to about 10 wt. %, based on the total weight of the emulsion composition, of a phospholipid emulsifying agent, wherein the phospholipid emulsifying agent comprises about 0.001 to about 1.0 mmol of primary ammonium functional group per gram of the phospholipid emulsifying agent, and wherein the oil-in-water emulsion and the foam composition are free of weighting agents and gum acacia.
