Answer to Question #30194 in Physical Chemistry for MEGAN PARKER

Question

I have developed a soap bubble solution (like the kind kids play with, but for making giant soap bubbles) and I want to store it in a concentrate form, to be diluted later.

I’m using 6.5 g. of guar gum powder and 7 g. baking powder per 7 fl. Oz. of Dawn Professional Manual Pot & Pan Dishwashing Detergent. When diluted into 1 gallon of water, the mixture is perfect for making very large soap bubbles.

HOWEVER - when stored in its concentrated state, the guar gum and baking powder settle out of the detergent within a day or two, leaving a layer of sediment at the bottom of the container, which must be mixed back into the detergent before dilution.

HOW CAN I PREVENT THIS SETTLING FROM OCCURRING, WHILE ALSO MAINTAINING A POURABLE, FLUID CONSISTENCY?

I really need a shelf stable concentrate that does not separate!
