pH and Color
Lise
Here’s a fun little demonstration of how a change in pH can make a difference to certain ingredients.
A handcrafted blueberry glycerite was added to a surfactant and the pH change was instantly evident in that the color changed from a bright pink to a blue-grey.
Those little pink spots are the glycerite before the surfactant was added to the mix. The blueberries were added to demonstrate the natural color of blueberries.
