I wanted to know what is the best container to keep bath salts that have essential oils added to them? I have heard that plastic and paper are no good because the oils will wick out/ escape from the salt. What is good to package bath salts with oils, besides glass jars? ~Jill
Glass is definitely the best material to package products that contain Essential Oils. Since glass is not porous, it keeps the Essential Oils from wicking out or eating away at the packaging. Unfortunately, packaging products in glass can be expensive and sometimes dangerous. For example, packaging a salt scrub in a glass jar can be dangerous if it is dropped in the shower or tub.
I've found the next best alternative to glass packaging is high density PET plastic. PET Plastic Jars and bottles can effectively contain products containing Essential Oils for some time before they begin to break down. (If they ever break down) These crystal clear jars and bottles also showcase colored salts and other products quite well. These are a great solution for bath salts, scrubs, and other products that contain Essential Oil.
PET cannot, however, serve as long term storage for pure Essential Oils. PET can be used to temporarily store Essential Oils, but even high density plastic will eventually be corroded by Essential Oil, especially Citrus or Spice Oils.
Do you have another packaging option that Jill could use for her Bath Salts? If so, please tell us about it in the comments below.
