Rebatching perfume to make a room spray
Hi all - I have a load of perfume which I am rebatching to make a room spray. The perfume formula is simply fragrance, alcohol and a small percentage of essential oil to complement the fragrance and for the brand concept & identity. I have read all sorts of conflicting info about the differences between a perfume and a room spray. My main question is - can I just increase the dilution of alcohol? I am planning to strenthen the base and middle notes through increasing the concentration of EOs in there slightly. I am concerned about both safety (specific to the high concentration of alcohol - I would add a warning re people,pets and open flames but also would be encouraging people to spray a highly flammable liquid in their homes) and also performance - I read that the warmth of the skin helps to bring the middle and base notes to the forefront so spraying a perfume formula on cold surfaces in a room would not have the same fixation and performance. I have considered adding glycerin to increase the viscosity and dilute the alcohol so that the oils don evaporate as quickly - could this be a useful thing to do? Thanks so much in advance for your thoughts!

Room spray/air freshener perfumes are formulated differently to those used for colognes or for personal application and merely diluting a fine fragrance type of perfume oil, as you rightly hint, will not be very successful in an air freshener.

Thanks johnb - can i just clarify if you are referring mainly to the fragrance notes or the carriers - or both? Thanks

Mainly to the fragrance.
A fine fragrance is traditionally created with top, middle and base notes.
Air fresheners do not require a full middle and base note character and so unless these are modified from the original fragrance you do not get the best effect. In some extreme instances, you can get quite unpleasant results (this is rare, though!)
