Stability cream
Posted by David on February 10, 2016 at 9:52 amIs this a sign of instability - or is it “only” air in the sample?
From the top it looks fine.David replied 9 years ago 3 Members · 7 Replies -

You need to upload the picture to some hosting service (like Flickr). Then link the address to the picture.

that looks like the product’s been filled cold, and the non-fluid nature of the product (hence, uneven filling) has led to air cavities being formed

I should also have mentioned that the left one was stored @ 40C for a month- the right one @RT 1 month. The bubbles were not possible to see directly after filling (or were very small) - they kind of “grew” after a while - that is why I was considering emulsion instability.
