Relating to or having the properties of an antiseptic; preventing or inhibiting infection.
From 'antiseptic' combined with the adjectival suffix '-al', though this form is archaic and 'antiseptic' itself now serves as the primary adjective.
This older form of the word shows how English evolves—we've mostly dropped the '-al' ending and now just say 'antiseptic', which is more efficient and easier to pronounce.
