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.
