detergent
B2Everyday, technical, commercial
Definition
Meaning
A cleaning substance, typically in liquid, powder, or gel form, designed to remove dirt, grease, and stains from surfaces, fabrics, or skin.
Any chemical agent, often surfactants or enzymes, that breaks down and suspends impurities to facilitate their removal, used in contexts ranging from household cleaning to industrial processes and biochemistry (e.g., lab reagents that disrupt cell membranes).
Linguistics
Semantic Notes
While often used interchangeably with 'soap' in casual conversation, 'detergent' technically refers to synthetic or non-soap cleansing agents. Soap is made from natural fats and alkalis, whereas detergents are derived from petrochemicals or oleochemicals. The term is also used in molecular biology for agents that solubilize proteins and lipids.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'дезинфектант' (disinfectant). 'Detergent' is 'моющее средство' or 'детергент'. It cleans but does not necessarily disinfect.
Common Mistakes
- Using 'soap' and 'detergent' as perfect synonyms in technical contexts. Saying 'dish soap' for a synthetic detergent product is common but not chemically precise. Using 'detergent' as a verb (it's primarily a noun).

Frequently Asked Questions
Soap is made from natural fats/oils and an alkali, forming salts of fatty acids. Detergents are synthetic surfactants derived from petrochemicals or oleochemicals. Detergents generally work better in hard water and have a wider range of applications.
Primarily uncountable when referring to the substance (e.g., 'add some detergent'). It can be countable when referring to types or brands (e.g., 'different laundry detergents').
A detergent containing enzymes (like proteases, lipases) that break down organic stains (e.g., blood, food, grass) at lower temperatures, making it more energy-efficient.
No, in modern English, 'detergent' is not used as a verb. The related verb is 'deterge' (to cleanse thoroughly), but it is rare and technical. Use 'clean with detergent' or 'wash' instead.
