How to Make a Diffuser Base
- 1). Place the funnel in the bottle opening. Pour the dipropylene glycol into the bottle while holding the funnel steady to prevent spills.
- 2). Add the perfumer's alcohol to the bottle and remove the funnel. The alcohol prevents the diffuser base from being too thick, which prevents it from drawing up the diffuser reeds.
- 3). Add the fragrance or essential oils to the mixture with a different dropper for each scent. Screw on the bottle's lid and gently swish the base.
- 4). Store the diffuser base in a tightly-closed bottle until ready for use. To use the diffuser base pour it into a decorative glass bottle with 10 to 12 new reeds.
