Fragrance oils can be used as perfume, reed diffuser oils or as oil for burners. Fragrance oils come in many scents, and can last much longer if they are diluted—or "cut"—with another oil made from dipropylene glycol (DPG). DPG is is a common carrier oil used to cut fragrance oils to make them more effective. DPG can make your fragrance oils last longer while maintaining the same scent.
Set up your work area by covering the work surface with a towel to absorb spills. DPG and fragrance oil can damage painted and finished surfaces.
Mix equal parts DPG and fragrance oil in plastic bottle to prepare the oil for an oil burner or diffuser. For example, if you want 2 oz. of oil, use 1 oz. of DPG with 1 oz. of fragrance oil. Shake the capped bottle vigorously for 30 seconds. Store in a cool, dark place.
Mix two parts DPG with one part fragrance oil in plastic bottle to prepare oil for reed diffusers. Shake the capped bottle for 30 seconds and store in a cool, dark place.
Mix three parts DPG with one part fragrance oil in a plastic bottle to prepare oil for perfumes. Shake the capped bottle for 30 seconds and store in a roll-on perfume bottle.
