Morphology

disinfectant = disinfect (transparent) = dis + infect + ant

The noun meaning 'agent used for disinfecting' is a straightforward and productive derivation from the verb 'disinfect'.

Etymology

Disinfectant begins with dis- meaning 'not' and the root infect meaning 'to cause disease', as in infection. So a disinfectant is a thing that makes surfaces 'not infected' by killing germs and helping to prevent illness.
