Bubble encapsulation via silicilic acid complexation

摘要

Disclosed are methods of preparing stable gas-in-water dispersions by silicic acid complexation of micron-sized gas bubbles, and stable dispersions prepared by silicic acid complexation. Compositions and products comprising the dispersions are also disclosed. Dispersions may be stable over an extended period of time at room temperature.

主权项

1. A method for encapsulating bubbles, said method comprising mixing a gas-in-water dispersion and a solution comprising at least one silicate salt, wherein:
a. the gas-in-water dispersion comprises at least one cationic surface active agent in the aqueous phase, and a dispersed gas phase comprising bubbles; and b. the solution comprising at least one silicate salt has a pH ranging from about 6.0 to about 10.0; wherein the volume of the gas phase in the gas-in-water dispersion comprises less than about 60% of the gas-in-water dispersion.
