Emulsifiers/Solubilizers for Oil/Alcohol/Water Spray

For a liquid product in a spray bottle containing 20% oil, 20% alcohol, and 60% water, you need an ingredient to combine the oil and water phases while maintaining a low viscosity suitable for spraying. You can use either a solubilizer to create a clear or translucent solution, or an oil-in-water (O/W) emulsifier to create a fine emulsion.

Here are some ingredients that can help combine the oil and water in your formula:

• Heptyl Glucoside: A natural-derived solubilizer and O/W binder that mixes into the water phase. It is effective for dissolving oil-soluble ingredients into water and can help maintain a clear or translucent liquid.
• C12-15 Pareth-12: A non-ionic O/W emulsifier and solubilizer. It is soluble in both water and oil and can effectively bind the oil phase into the water phase, suitable for creating low-viscosity systems.
• Ceteth-20: An O/W emulsifier that mixes into the water phase. It can help create a stable emulsion.
• Ceteareth-10: An O/W emulsifier that mixes into the oil phase. It may require heating to incorporate.
• Polyglyceryl-10 Palmitate: An emulsifier that mixes into the oil phase.

When selecting an ingredient, consider the desired appearance (clear vs. milky emulsion) and the specific type of oil and alcohol used, as this can affect compatibility and required usage levels. It is recommended to start with a low percentage and adjust as needed to achieve stability and the desired clarity/texture.
