The origin of the Fragrance Lamp goes back to 1898 when a French pharmacist created the Catalytic Combustion system to disinfect the air in the hospitals.
The basis of the Lamp Fragrance, and the important fuel which keeps the catalytic process working, is an alcohol called isopropyl alcohol. A very common alcohol, it is the same form of alcohol which is commonly used in hospital anti-bacterial hand washes for example. The other ingredients are distilled water, and the fragrance compound itself.
