Store cosmetics in a cool, dry place, out of direct sunlight.
This product does not contain preservatives because it is inert and will stay clean of bacteria, molds, and yeast for 2+ years if used and stored as directed. Using scoops and bags limits physical contact, which reduces risk of contamination. If concerned, spray the products and accessories with 70-99% isopropyl alcohol. Allow to dry for at least 10 minutes.
If this product is mixed with a mixing medium, your finished item is subject to the mixing medium’s shelf life. A wet product without preservatives will be good for only a few days unless allowed to dry.
