STORAGE - Is it better to store my finished product in a refrigerator?

I have batches of my cream moisturizer packed in aluminum tubes. I am just wondering if it is worth storing them in a refrigerator or beverage cooler in around 40-45 degrees. Will it help prolong shelf life or should I just store them at room temperature?

I am using euxyl pe 9010 as the preservative and my formula contains oils that were emulsified.

  • All other things being equal, refrigerator stored products will last longer.

  • Will it degrade emulsion?
  • If you have a stable emulsion, probably not. If you have an unstable emulsion, maybe. This is why we test stability for every formula.
