Preventing Separation in Reed Diffuser Formulas

When creating a reed diffuser formula that combines fragrance oils, flavors, and essential oils, separation can occur because these oil-based ingredients are not miscible with water or water-based solvents typically used as the base for diffusers. To prevent this separation and create a stable, clear solution, you need to use a solubilizer.

A solubilizer helps to disperse the oils evenly throughout the water phase by forming micelles that encapsulate the oil droplets, keeping them suspended and preventing them from separating over time.

Here are some solubilizers that can be used for this purpose:

• Flora Solve™ Clear: This is a popular choice for dissolving fragrance and essential oils in water-based systems without using alcohol. It helps create clear, stable microemulsions. The typical usage ratio is 2-5 parts Flora Solve™ Clear to 1 part fragrance/oil, but this can vary depending on the specific oils used.
• Ultra Solve™: A high-performance solubilizer that is effective for dissolving various oils, including essential oils and fragrances. It can be used when Flora Solve™ Clear is not sufficient to achieve clarity.
• Free Solve™ (PEG-Free Solubilizer): A non-ionic, high-performance solubilizer that is PEG-free. It is effective for dissolving oils, perfumes, and essential oils in water to achieve clarity.
• PPG-6-Decyltetradeceth-30: Another solubilizer option suitable for binding water and oil phases.

How to Use a Solubilizer:

Generally, you should first mix the solubilizer with the fragrance oils, flavors, and essential oils until they are well combined. Then, gradually add this mixture to your water or water-based base, stirring continuously until a clear, stable solution is achieved. Avoid adding the water base directly to the solubilizer-oil mixture, as this can result in a thick gel.

The exact amount of solubilizer needed will depend on the specific oils and the total concentration of oils in your formula. It is recommended to start with a ratio suggested by the supplier (e.g., 2-5 parts solubilizer to 1 part oil) and adjust as needed through testing to achieve a clear and stable product.
