question about centrifuge

Postby glutacareshop » Thu May 31, 2018 1:21 pm

want to order a machine Centrifuge To test to see if the formula is stable or not? Settling or stratifying? but still do not know How long, how fast and how long is the centrifuge? How much is the real time? For example, we don't want our products to be stratified or precipitated before 6 months, but can be stratified after 6 months (because customers who have used them probably have used up). This 6-month period is equal to the time in the blender. how many minutes and how many RPM to spin, etc.

Hello, usually Centrifuge at 3,000 rounds / minute, duration 30 minutes, in case you think The recipe may be stored in a hot place. The formula can be heated to 40-45 degrees, then Centrifuge 30 minutes at 3,000 cycles as well. Test to obtain a shelf life of 6 months, but means a standard test which, if passed, cosmetics should last for at least 2 years if there are no other problems such as the formation of germs. Tested to get shelf life for only 6 months. I can't do it.
