Etymology: "Detergents" is the plural of "detergent," which comes from French "détergent," itself from the Latin "dētergēns," the present participle of "dētergeō." That verb combines "dē" meaning "off" with "tergeō," meaning "wipe" or "polish," so the underlying idea is wiping something clean away. The Latin root is also what gives English "terse" and "tergal" relatives in the sense of rubbing smooth, though those words come through different paths. The core image is physical: something wiped from a surface. A detergent, in its original sense, was an agent that cleansed by removing, and the word has carried that sense of taking dirt off ever since. Its use for soaps and washing compounds came much later than its Latin origin, so the modern chemical meaning is a new application of an old idea of scrubbing away.

Synonyms: cleaners, cleansers, soaps, surfactants, agents
