A different formulation entirely
A room spray is a solution, not a wax. It needs a solvent system that will carry fragrance oil and spray cleanly without separating.
Nothing you know about wax applies. What does transfer is your fragrance library and your brand.
What is in one
A solubilizer or a carrier that lets an oil sit in a mostly alcohol or water base.
Alcohol, typically, which dries fast and carries scent well.
And a fragrance at a level set by the supplier and by the IFRA category, which for an air freshener differs from the candle category.
The common failure is an oil and water mix with no solubilizer, which separates in the bottle and sprays unevenly. It looks like a formulation you can guess at and it is not.
Packaging and flammability
A fine-mist sprayer with a dip tube, in glass or PET.
Alcohol content raises a flammability question, which reaches labeling and shipping. A high-alcohol product may be restricted by carriers and by air freight, and that is worth checking before an online range is built on it.
It is also a product that will be sprayed near fabric, which makes a staining warning worth carrying.
Where it fits
As a lower-price companion to a candle in the same fragrance, which is a genuinely strong pairing.
The development cost is a formulation problem rather than a testing one, which makes it faster than a new candle fragrance and slower than a wax melt.
