Choosing Solubilizers for Air Spray and Surface Cleaner Formulas

Asked by: thatorn1999 On: June 21, 2026 Product Type: Cosmetics Answered

Question

Hello, I am interested in using the shop’s Solubilizer to develop Air Spray and Surface Cleaner formulas, so I would like to ask for more information.

From the website information, I found Flora Solve Clear, Ultra Solve, and Eco Solve. The text states that Ultra Solve has higher performance than Flora Solve Clear, while Eco Solve has performance equivalent to Ultra Solve. I would like to ask for more details as follows:

  1. If using only to solubilize Fragrance Oil and Essential Oil in water, which one has the highest performance?
  2. If comparing the clarity of the finished formula, how should Flora Solve Clear, Ultra Solve, and Eco Solve be ranked?
  3. What is the main difference between Ultra Solve and Eco Solve, since their performance is stated to be similar?
  4. For a Room Spray / Air Spray formula with fragrance around 0.5-3%, which one does the shop recommend most?
  5. For a clear water-based Surface Cleaner formula with fragrance around 0.3-0.5% and mild surfactant already in the formula, which one should be selected?
  6. Can all 3 products withstand storage at 40-45°C similarly, and which one has the best long-term stability?
  7. Please provide the recommended usage ratio for each product for Fragrance Oil and Essential Oil.

Thank you.

Answer

Based on the current catalog data, the practical ranking is:

Question Recommended interpretation
Highest solubilizing power for fragrance oil / essential oil in water Eco Solve™ ≈ Ultra Solve™ > Flora Solve™ Clear. Ultra Solve™ is listed as higher efficiency than Flora Solve™ Clear, while Eco Solve™ is listed as performance-equivalent to Ultra Solve™ and usable at the same concentration.
Best clarity in finished clear water systems Usually Eco Solve™ or Ultra Solve™ first, then Flora Solve™ Clear. Eco Solve™ specifically states excellent clarity and no yellowing; Flora Solve™ Clear is also clear/colorless and can make clear stable microemulsions, but may need higher ratio for difficult oils. Final clarity still depends strongly on the exact fragrance/essential oil.
Main difference: Ultra Solve™ vs Eco Solve™ Both are high-performance solubilizers. Ultra Solve™ is the higher-price option and is positioned for difficult-to-solubilize oils. Eco Solve™ is positioned as a lower-cost alternative with performance equivalent to Ultra Solve™, same-use replacement at the same concentration, neutral pH/no yellowing, and excellent clarity. Their compositions are also different.

For a Room Spray / Air Spray with fragrance around 0.5-3%, we would normally start with Eco Solve™ because it gives Ultra Solve™-level performance with better cost efficiency and is described for dissolving perfumes/essential oils in water with excellent clarity. For easy fragrance oils at the low end, Flora Solve™ Clear can also work and is often more economical, but at 2-3% fragrance it may require a high solubilizer dose and may make the spray feel thicker.

For a clear Surface Cleaner with fragrance around 0.3-0.5% plus mild surfactants, Eco Solve™ is also the best first trial. The surfactants already in the formula may help clarity, so the required level may be lower than in plain water. Ultra Solve™ can be kept as the stronger/high-cost option if a particular fragrance remains hazy.

Suggested starting ratios for lab trials:

Product Fragrance oil Essential oil Notes
Flora Solve™ Clear Start 2-3:1, test up to 5:1 Start 2-3:1, difficult oils up to 5:1 Catalog ratio is 2-5 parts solubilizer to 1 part perfume/oil. Some essential oils need only 2:1, while some need 5:1.
Ultra Solve™ Start 1-3:1, increase if cloudy Start 2-4:1, increase if cloudy Catalog use level is 1-10%; exact oil:solubilizer ratio is not fixed in the product description, so clarity testing is needed.
Eco Solve™ Start 1-3:1, increase if cloudy Start 2-4:1, increase if cloudy Can be used in place of Ultra Solve™ at the same concentration; catalog use level is 1-10%.

For heat/storage: Flora Solve™ Clear specifically states stability at 40°C and 4°C. Eco Solve™ states hot/cold resistance and excellent clarity, but the catalog storage instruction is still room temperature, avoid sunlight/heat. Ultra Solve™ also has room-temperature storage and avoid heat/light guidance. For a product expected to sit at 40-45°C, please run an accelerated stability test on the exact fragrance system, because 45°C long-term stability is not confirmed equally for all three products in the catalog data. A practical screen is 40-45°C, room temperature, and 4°C/freeze-thaw, checking clarity, separation, odor change, viscosity, and pH over time.

Processing tip: premix the fragrance/essential oil with the selected solubilizer until uniform, then slowly add that premix into the water phase while stirring. Do not add water into the concentrated solubilizer/oil premix, because Flora Solve™ Clear data warns this can form a thick gel.
