What does detersive mean?
Detersive describes something that cleanses — that is, something capable of washing away dirt, grease, or other impurities. The word functions chiefly as an adjective ('a detersive solution') but can also serve as a noun meaning a cleansing agent itself, much like the word 'detergent'. Derived from the Latin verb 'detergere', meaning to wipe off or wipe away, it entered English in the seventeenth century and has long been at home in scientific and medical writing, where precision matters more than familiarity. You might encounter it in pharmacology texts describing a detersive lotion, in older chemical treatises discussing the detersive properties of alkalis, or in historical accounts of hygiene. Though rare in casual conversation, where 'cleansing' does the job more naturally, 'detersive' lends writing an exact, scholarly tone and connects pleasingly to its Latin cousins, including 'terse', which originally meant polished smooth by rubbing.
Having cleansing properties; serving to remove dirt, grease, or impurities.
"Alkalis were prized by early chemists for their marked detersive power."
Chiefly used in technical, medical, or historical-scientific contexts.
A cleansing agent; a substance used for washing away dirt or grease.
"The apothecary stocked several detersives alongside his oils and tinctures."
Now rare; 'detergent' or 'cleanser' has largely replaced it in modern usage.
Used only when the word functions as a noun referring to multiple cleansing agents.
"The laboratory compared the effectiveness of various alkaline detersives."
Before 'detergent' took over the laundry aisle, English had a more scholarly word for anything that washes away grime — and it comes from the same Latin verb that gives us 'terse', literally 'wiped clean'.

Etymology of detersive
The word derives from the Latin verb 'detergere', formed from 'de-' (away) plus 'tergere' (to wipe), whose past participle 'detersus' means wiped clean. English adopted 'detersive' in the early seventeenth century as both an adjective and a noun for cleansing substances. It shares this root with 'detergent' and 'deterge', and, more distantly, with 'terse', which in Latin described surfaces made smooth by wiping or polishing.
