step-by-step instructions
- Step 1. Measure your base. For a 1-gallon batch, pour 122.88 oz of Room Spray/Body Spray Base into a clean mixing container.
- Step 2. Add fragrance oil at your target load: 4–9% for room sprays, 2–6% for body mists. For a 4% room spray batch, add 5.12 oz fragrance oil.
- Step 3. Stir gently for 2–3 minutes until fully blended. Avoid vigorous shaking — this can introduce bubbles.
- Step 4. Let the blend rest 24–48 hours before bottling. This allows the fragrance to fully bind and any cloudiness to settle.
- Step 5. Test for clarity and separation. If the blend stays clear and uniform, bottle into labeled spray containers.
example batch
For Makers: Add fragrance oil at the appropriate rate depending on use and IFRA limits: Body Spray: 2–6%, Room Spray: 4–9%. Mix until uniform. No solubilizer is typically required, but clarity may vary depending on fragrance. Let rest for 24–48 hours before bottling. Example Batch (Room Spray): 122.88 oz base + 5.12 oz fragrance oil = 128 oz finished product (4% load). Always confirm IFRA limits for your fragrance oil and test each blend for clarity, performance, and separation before full production.
pro tips for makers
- Always check IFRA limits for your specific fragrance oil before setting your load percentage.
- Start at 4% fragrance and increase in 0.5% increments until you reach your desired strength.
- Some fragrance oils may cause slight cloudiness — test small batches before scaling up.
- Use PET or glass bottles with fine mist sprayers for the best customer experience.

common questions
Do I need a solubilizer?
No — our alcohol-based base is formulated for excellent fragrance solubility. Most oils blend clear without additives.
Can I use this as a body spray?
Yes — keep fragrance load at 2–6% for body mist applications and confirm IFRA Category 4 limits for your oil.
Why does my spray look cloudy?
Some fragrance oils contain heavier notes that can cause haze. Let it rest 48 hours; if cloudiness persists, reduce your fragrance load slightly.
