Packaging an emulsion to keep it stable

[spiridij]

Hello,

We have a highly viscous paste emulsion that we are having a hard time keeping stable. We currently use a kitchen-aid mixer to mix it and we transfer it from the mixing bowl into a sheet of saran and then into a sealed jar. This isn't working since we need to open the jar to pull material from the bulk and it's having an effect on the paste over time. Any suggestions on how we can transfer the paste from the mixing bowl, quickly, since it's very sensitive to moisture loss, and into some sort of packaging that will keep it stable. Maybe a caulking tube or something?

Is not storing the material at all an option?

Assumptions:
- If you are only making a relatively small jar's worth of material at a time, and

- Judging from your previous post about the storage stability, 1 jar lasts for several months, and

- Making that small batch in the stand mixer is not overly taxing, and

- The need for this material is infrequent enough to not require a constant stock on hand.

If those assumptions are all accurate, I would suggest just making this paste fresh each time you need it and only the amount needed and avoid storing it entirely.

No, unfortunately we will need to store the material. We are going to be running bulk stability experiments so we are looking into storage solutions.

Figure out a standard size allotment and design a robust container that won't leak. Then, grab whatever number of containers needed and use them.

Good luck,

I like Latex's idea, decide how much you what at a time and package in that size.
We used to use a product that was similar, and we had to stir the barrels periodically.
We has a low speed paddle that was used to stir them.
Our vendor wanted us to put the barrels on rollers and slowly rotate them all of the time.
