Old oils and uses
Hi, I'm a newbie to posting to this section of gardenweb even though I have lurked here for a while.
I have some fragrance oils that due to a move then a few years of being a caregiver I don't know what they are anymore. The labels have worn off or faded, and some of the companies aren't in business anymore. So I don't know if they are skin safe or just for candles. Is there anyway I can find out or is it best just to use them for other uses like potpourri or in diffuser. If they are a few years old, is it still safe to use them for candles?
