Emulsifier/Solubilizer for 95% Water, 5% Oil Mosquito Repellent Spray

For making a mosquito repellent spray with 95% water and 5% oil, you will need an emulsifier or solubilizer to help the water and oil combine well and prevent separation.

Here are some suitable ingredients for a formula with water as the main component (Oil-in-Water) and a low oil percentage:

• C12-15 Pareth-12: This is a non-ionic Oil-in-Water emulsifier with an HLB value of approximately 14.4. It is suitable for emulsifying oil in water or used as a solubilizer. It can be used at a concentration of 1-10%.
• Heptyl Glucoside: This is a high HLB emulsifier/solubilizer suitable for dissolving oil-soluble ingredients in water-based formulas. It can be used at a concentration of 1-15%.

Both of these ingredients can help disperse 5% oil in 95% water. The choice depends on the desired clarity or texture of the spray and the type of oil used. It is recommended to test in small batches to find the most suitable concentration for your specific formula.
