Title: Menthol Crystals
Post by: Kivi on November 11, 2009, 11:36:13 AM
I was just about to purchase some of your menthol crystals, when I suddenly thought of a question.
I only need 1 to 2 ounces to make a certain compound/ointment "recipe", and you sell the crystals in 1/2-lb quantities. Is there any kind of expiration date on these menthol crystals? Do they ever go "bad" or would they still be good in, say, 10 or 15 years?
Thank you for helping me choose the crystals that will work best for me.

Pure Menthol Crystals (http://www.steamsaunabath.com//catalog/product_info.php/cPath/64_75/products_id/1755), like those sold by Steam Sauna Bath, have an ideal shelf life of 1-3 years. This is provided they are stored in a cool (60-80 degree), dark and dry place. Menthol Crystals do not go bad, but age, excessive heat, light, and moisture may reduce their potency.
