Explanation for Separation of Dipropylene Glycol and Reed Diffuser Base Type 1

Based on the information for Reed Diffuser Base (Type 1), this product is specifically formulated without containing Dipropylene Glycol or Propylene Glycol.

Mixing Dipropylene Glycol directly with Reed Diffuser Base (Type 1) is likely causing the separation you observed because these two substances are not compatible or miscible with each other in this formulation. The base is designed to work with fragrance oils, not necessarily with added solvents like Dipropylene Glycol.

Recommendation:

To avoid separation, it is best not to mix Dipropylene Glycol directly with Reed Diffuser Base (Type 1). Use the Reed Diffuser Base (Type 1) as intended with your fragrance oils. If you experience separation when mixing fragrance oil with the base, the product description suggests pre-mixing the fragrance with Ethyl Alcohol first before adding it to the base, although this specific method might not resolve the issue when adding Dipropylene Glycol itself.
