Bubble solution formula and method of manufacture

Abstract

An improved bubble solution for use with bubble blowing wands or toys and the method of manufacture is disclosed. The bubble solution contains water and functional amounts of EDTA-2Na, propylene glycol, lauryl betaine, a natural starch (such as Natrosol™ 250HHR), and a preservative (such as Phenova™). The bubble solution is made by: (1) heating de-ionized water in a mixing tank; (2) adding EDTA-2Na and the natural starch into the hot water and stirring until the solution is uniform; (3) mixing propylene glycol, lauryl betaine and the preservative in a separate container until uniformity is reached; and (4) pouring the solution from step (3) into the mixing tank while the water is still warm and the natural starch is dissolved. The bubble solution according to embodiments of the present invention produces more bubbles than presently available bubble formulas, using the same wand and same air pressure.
