Looking for the best protecting packaging for EOs : Amber or blue glass ?What color would stop more efficiently sun light and the most harmful wave lengths for EOs ?
The industry standard certainly is amber glass. As essential oils should be stored in the dark (and citrus oils should be stored in a fridge) this is maybe a little academic the vendors who use blue, clear or green would argue. Here is some good information on violet glass http://www.miron-glas.com/en/Biophotonics
