Making a reed diffuser base:

• Dipropylene Glycol  20-60% depending on your particular fragrance.
• Fragrance 10-60%
• Caprylic Capric Triglyceride:  20-60% depending on your particular fragrance.
• Ethanol  10-30% depending on your particular fragrance.
• The ideal Reed Diffuser Base balances the solubility of the perfume with the speed of travel up the reed. It is ideal to balance the speed of diffusion so that the perfume oil lasts for a long time and doesn’t leave the base behind as it travels.  If the mixture is too thick it may not be taken up by the reed, if it too volatile the smell might not last long.  As every fragrance is different the ideal formula may be different for everyone.  The DPG plays an important role as a solvent in this mixture and while there are other solvents that might work in its place, it has so far been impossible for us to find a more natural alternative.
