All of my emulsions have been getting microbubbles, on the surface it looks smooth but to anyone looking hard enough there are itty bitty bubbles all throughout and I don't know what I am doing wrong. Someone said get an overhead stirrer and I finally invested in it and still, bubbles, the faster it stirs the smaller the bubbles get the harder they are to pop or escape.
Currently mixing a water phase of
Deioinzed Water
Panthenol
Cetac
Silk Peptides
Hydro Flax Seed
Vegetable Glycerin
Aloethix, a cosmetic aloe gel
Added guarcat
Still, tiny annoying bubbles, should the stirrer be deeper? slower, faster? I am sick of wasting ingredients

I'm guessing that the emulsion is otherwise stable, that it isn't separating over time and therefore that the bubbles are just air?
Usually you don't want any air/product/stirrer interface as that's the most likely route for air to be incorporated. Deeper is usually better to avoid the stirrer dispersing air that is being 'funnelled' through the vortex.
You'll still want it fast to ensure an emulsion is being formed effectively.
