Major component · the claim says “the main compounds found were alcohols, chiefly”
In indoor air sampled at six sites of a French teaching hospital, including the reception hall, the main compounds found were alcohols, chiefly ethanol and isopropanol, together with ethers and ketones; alcohol levels varied greatly over time, probably because of the intensive use of alcohol-based hand rubs.
Scope: One hospital sampled over three days; sites included a reception hall and care areas rather than corridors, and it measures air composition, not odour. CLM-HOSPITAL-001 ↗

WHAT THIS MEANS
SmellBook lists a molecule only where a VERIFIED claim names it, in the role and scope that claim states. A molecule reported in a smell's evidence is not the whole smell: most smells come from many compounds together, and the studies measured particular samples, such as one cultivar, an essential oil or a cooked product.
