Question

I want to experiment with making a water-based mosquito repellent spray using essential oils as ingredients. I would like to ask what solvents (solubilizers) can be used to dissolve the essential oils in water. Thank you.

Answer

Solvents for Dissolving Essential Oils in Water for Spray Formulations

To create a water-based spray formulation using essential oils, you need a suitable solubilizer to disperse the essential oils evenly in the water phase. Essential oils are not naturally soluble in water.

Based on your requirement to dissolve essential oils in water for a spray, the following solubilizers are suitable options:

  • Flora Solve™ Clear (Fragrance Solubilizer): This is an effective and economical option specifically designed to combine essential oils and fragrance oils with water without using alcohol. It helps create clear, stable solutions. To use, mix Flora Solve™ Clear with the essential oil first (typically 2-5 parts Flora Solve™ Clear to 1 part essential oil, depending on the specific oil), then add this mixture to the water phase while stirring.
  • Ultra Solve™: This is a higher-performance solubilizer that can dissolve a wider range of oils, including essential oils, and can handle higher oil concentrations than Flora Solve™ Clear. It is used when Flora Solve™ Clear is not sufficient to achieve clarity or stability. Mix Ultra Solve™ with the oil phase first, then add to the water phase. Recommended usage rate is typically 1-10%.
  • Eco Solve™: This offers performance comparable to Ultra Solve™ but at a lower cost. It is also effective for dissolving essential oils and other oils in water, providing good clarity and stability. Like Ultra Solve™, mix it with the oil phase first before adding to water. Recommended usage rate is typically 1-10%.

When formulating, always mix the essential oil with the chosen solubilizer thoroughly before adding the mixture to the water phase. Avoid adding water directly to the solubilizer/oil mixture, as this can cause it to thicken or gel. The exact ratio of solubilizer to essential oil may need to be adjusted based on the specific essential oil used to achieve a clear and stable solution.
