detergent
dih-TUR-juhnt
/dɪˈtɜːr.dʒənt/
A chemical cleansing substance that acts similarly to soap, designed to break down oils and remove dirt from textiles or surfaces.
Detergents are synthetic formulations that dissolve easily in hard water, unlike natural soap which forms scum.
The story behind the word. Formed from Latin 'de-' (away) and 'tergere' (to wipe), 'detergent' originally meant anything that wipes clean. Modern chemistry adopted the word in the early 20th century to describe synthetic cleansers that strip oils without creating soap scum.
