All my mixing batching containers are stainless jacketed non pressurized vessels. Always the same ones. I use city water cooling to reduce the temp. after homogenizing. I can surely try a short homogenization followed by a low shear cooldown which takes 2-3 hours. My cooldown adds are Germall Plus, Panthenol and Vitamin E. I used to add the dimethicone ingredient after cooldown (~45C) because I had heard anecdotally that it can decompose at higher temps but others said that was not the case and I haven’t seen any problems adding at 75C. I do wonder though because the dimethicone surely imparts gloss and flow to the product. Maybe I should move it back to cooldown adds?

I have tried to remove the mixer after the initial 30min blend. Sometimes its fine but other times you can see phases separating. On these occasions I keep blending till it has cooled to 61C. Not sure what causes the different outcomes.

I heat and hold the oil phase at about 75 C for 1 hour the water phase is brought up to 75C just before mixing. Vessels are water jacketed stainless steel. I’ve used the same vessels every time for good and bad batches. I homogenize from mixing at 75 C for about 30 min. then continue while cooling until about 61C

Very interesting point. I was wondering if I was loosing significant water in the heating phase even though the vessel is covered. Both creams seem quite stable. it is the appearance that is the issue. I might be right on the ragged edge of O/W vs. W/O. I’m not sure the viscosity is that different (no viscometer available) but you can see a difference when putting it into jars. Should I just start with more water to account for loss?
