Question

I would like to make a reed diffuser and plan to order the following two ingredients. Are they correct for this purpose?

1. Dipropylene glycol
2. Isopropylidenglycerin (Solketal)

Answer

Making a Reed Diffuser

For making reed diffusers, we specifically recommend using a dedicated Reed Diffuser Base. These bases are formulated to provide optimal fragrance throw and evaporation rate through the reeds.

We have a product called Reed Diffuser Base (Type 1) (Product ID 3352) which is specifically designed for this application. Using a dedicated base like this will generally give you better results for your reed diffuser project.

Question:

Can Reed Diffuser Base (Type 1) be used with essential oil blends? What is the recommended usage ratio?

Answer:

Using Reed Diffuser Base (Type 1) with Essential Oils

Yes, our Reed Diffuser Base (Type 1) is suitable for use with essential oil blends.

The recommended usage ratio is typically:

  • Reed Diffuser Base (Type 1): 70-75%
  • Fragrance (Essential Oil Blend): 25-30%

If you find that the essential oil blend separates from the base after mixing, you can try mixing the essential oil blend with a small amount of Ethyl Alcohol first before adding it to the Reed Diffuser Base (Type 1).
