Pure Orange 10 Fold Essential oil: A middle note with a medium to strong aroma, Orange Ten Fold has a sweet, citrus smell like the orange peels from which it is derived, but more intense and concentrated than regular orange essential oil or 5 fold.
Through distillation, terpenes are partially removed from the oil thus giving it a slightly stronger scent. Some terpenes are more likely to oxidize thus removing some will help improve the shelf-life of the essential oil for soaps and candles. (Ref: New Directions Aromatherapy)
