Pure Essentials - FRAGRANCE DESCRIPTIONS - Pure EssentialsOur regular line of fragrance lamp oil is a blend of alcohol and fragrance oil, a man-made fragrance. The "pure essentials" line is a blend of pure essential oil and alcohol. Pure essential oil is plant based and more expensive than regular fragrance oil, thus the difference in price. Both types provide good scent strength and burning results. Lamp oil made with the pure essentials will be available in plant-based scents only and is not available in the wide variety of scents that fragrance oils offer, such as Blueberry Cobbler, Fresh Linen, etc. Some folks prefer the "natural" blend of pure essential oils - it's truly a matter of personal preference.
