Air pockets on surface of face cream formula after a few weeks

Hello Chemists Corner community!

After filling my face cream formula inside a jar and securing tight, small air pockets appear on the surface of the formula. The consistency remains the same, only the appearance of small air pockets.

I was wondering, has anyone else come across this issue? I was going to start eliminating a few oils from the formula as well as increasing the mixing time.

I was also thinking it could be caused from a few bigger air bubbles bursting underneath and causing the surface to crater in.

Any insight would be greatly appreciated!

Thank you!


  • You haven't really given enough information for people to evaluate.

    Did you use a preservative?

    What are the ingredients.  If there is a reaction occurring between ingredients, we can only help if we know what might be in there.

    Were there air bubbles when you filled...and they just migrated to the surface?
