I bought some lotion base which came in a gallon jug. I want to scent it with essential oils without too much exposure to contaminants. Is there a way I am overlooking other than pouring it all out into another container adding the eo and stirring before returning to the jug again? It just seems like a lot of trouble. I guess you could pump out enough to fill one container at a time into a baggie and add the eo's and squish it around. Anyone have any advise or suggestions??? Many thanks!
