Linguistics
Semantic Notes
Primarily a technical term in chemistry, materials science, and the cleaning products industry. It refers to the measurable property or performance of a cleaning agent, not the act of cleaning itself.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage; the term is equally technical in both varieties.
Connotations
Neutral, scientific, industrial.
Frequency
Extremely low frequency in everyday speech in both regions. Its use is confined to specialized technical contexts.

Usage
Context Usage
Business
Used in R&D, marketing, and quality control for cleaning products, e.g., 'The new formula boasts superior detergency on oily stains.'
Academic
Common in chemistry, chemical engineering, and textile science papers, e.g., 'The study quantified the detergent's detergency on polyester-cotton blends.'
Everyday
Virtually never used in everyday conversation. One would say 'cleaning power' or 'how well it cleans' instead.
Technical
The primary domain. Used in specifications, lab reports, and product data sheets to describe measurable cleaning performance.

Examples
By CEFR Level
- This washing powder has good cleaning power. (Simplified alternative)
- How well does this cleaner work on grease? (Simplified alternative)

Learning
Memory Aids
Mnemonic
Think of DETERGENT + EFFICACY = DETERGENCY. It's the 'efficacy' or 'power' aspect of a 'detergent'.
Conceptual Metaphor
CLEANING IS PURIFYING / EFFECTIVENESS IS STRENGTH. Detergency is the quantified strength of a purifying agent.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'детергенция' (which is not a standard Russian word). The closest concept is 'моющая способность' or 'очищающая способность'. Do not translate it as 'детерминизм' (determinism) which is a false friend.
Common Mistakes
- Using it as a synonym for 'detergent' (noun). e.g., Incorrect: 'I bought a new detergency.' Correct: 'I bought a new detergent.'
- Using it in everyday contexts where 'cleaning power' would be more natural.
- Misspelling as 'detergance' or 'detergence'.

FAQ
Frequently Asked Questions
No, it is a specialised technical term used almost exclusively in chemistry, materials science, and the cleaning products industry. It is very rare in everyday language.
'Detergent' is a noun referring to the cleaning substance itself (e.g., washing powder, dish soap). 'Detergency' is an abstract noun referring to the measurable cleaning power or effectiveness possessed by that detergent.
No. You would describe your clothes as 'clean'. 'Detergency' describes a property of the cleaning product, not the state of the cleaned item. You could say, 'The detergent's high detergency resulted in very clean clothes.'
In non-technical contexts, phrases like 'cleaning power', 'cleaning strength', or 'how well it cleans' are perfect substitutes and are far more commonly understood.
