Cleaning Makeup Containers for Re-use
Wash them out with soapy water and completely let them dry. Don't forget to wash the inside of the cap. Before refilling them, spray the inside of the jars and the inside of the caps with alcohol and let dry. That should kill 99% of any bacteria. Never let moisture collect on the inside of a cap - it will become a petri dish of mold and bacteria.
Get as much lipstick out of the bottom as you can and wipe the inside out with a cotton swab. Do not try to wash it out with soap or water. Spray the inside with a bit of alcohol and re-fill. Like foundation and blush powders, lipstick does not contain water, so the risk for growth of mold or bacteria is extremely low.

For this reason, eye products must be very carefully manufactured and preserved to withstand constant introduction of germs.printing and typesetting industry.
