What is the ingredient in the Lamp Fragrance that actively kills coronavirus?

90% of each Lamp Fragrance isopropyl is alcohol and it is this, just as in hand sanitisers that is effective against coronavirus. The virus is surrounded by a lipid membrane, and the antimicrobial effect of the alcohol vapour is attributed to its ability to dissolve the lipid membranes and denature the proteins of the virus. The virus cell literally falls apart when exposed to alcohol vapour.
