The glass used in essential oil bottles can provide some protection against UV light. However, the level of protection depends on the type and thickness of the glass, as well as its color. Regular glass is effective at blocking most UVB and UVC rays but allows some UVA rays to pass through. UVA rays can potentially cause essential oils to oxidize and decrease in potency over time.
To enhance UV protection for your essential oils, consider using colored glass bottles. For example, amber or dark-colored glass bottles are known to offer better protection against light, including UV rays, compared to clear or light-colored glass bottles. Additionally, thicker glass may provide slightly better protection due to reduced radiation transmission.
If you want to maximize UV protection for essential oils stored in glass bottles, it's advisable to keep them in a cool, dark place away from direct sunlight. This practice helps preserve the quality and longevity of the oils.
