I will use an example:
you are making a serum with antioxidants. You are going to add hyaluronic acid powder to it or some other powder. Maybe it’s a thickener, viscosity agent, or something else. As is customary, you plan on using a hand held blending tool to fully incorporate this ingredient in your formula.
does this blending action introduce oxygen into your formula and expose your ingredients to it... which can lead to faster oxidation of not just the antioxidants but of your entire formula?
the way I understand it, the spinning of the blender creates a vortex which stirs in air. Or is that completely wrong?
for example when i think of gels that have carbomer, oftentimes there are tiny little air bubbles trapped inside the gel that never vanish. these bubbles I would have to think are causing some oxidative damage... at least more damage than if the product did not have any of these bubbles? Or is is negligible?
