Oil in Water Emulsion Observation

Interesting thing happened with my lotion.  I put the formula together and it looked great, however the next day it looked like a micro foam.  It had all these really tiny bubbles all through the cream, I don't think I have seen that before.  Has this happened to anyone else before?

    It could be trapped air escaping causing a bunch of little holes.

  • @JonahRay ; i hope thats what it is haha!  I'm doing a knockout right now to see if it might be the fragrance/preservative

    @chickenskin Do you have xanthan gum in the formula? It can trap air pretty well.

    Nothing in your formula looks to be particularly bad at trapping air. I would say its just an issue of incorporating too much air during production. Make sure a vortex thats reaching the blade doesnt form and if thats hard to prevent try using a baffle to suppress the formation of a vortex.

    Is it really foam or could it be oil drops (i.e. emulsion is not stable)?

    I see triethanolamine soap as a possible source which probably wasn’t quite visible initially. Now the foam/bubbles rising to the surface.
