Definition
Meaning and Definition
A cleaning agent in which the active part of the molecule carries a negative electrical charge when dissolved in water.
A type of synthetic detergent commonly used in household and industrial cleaning products, characterized by high foaming and excellent grease-removing properties due to its negatively charged surfactant molecules.

Common Mistakes When Using “anionic detergent”
- Mispronouncing 'anionic' as /ˈæn.i.ə.nɪk/ (stress on first syllable). Correct stress is on the third syllable.
- Using 'anionic detergent' as a catch-all term for any detergent, ignoring cationic and non-ionic types.
- Incorrect pluralisation: 'anionic detergents' is standard, not 'anionic detergent' for plural.
FAQ
Frequently Asked Questions
No. Soaps are salts of fatty acids, while anionic detergents are synthetic surfactants with a sulphonate or sulphate group. They behave similarly but have different chemical structures and properties, especially in hard water.
Some traditional anionic detergents were poorly biodegradable and caused foaming in rivers. Modern formulations are often designed to be biodegradable and meet strict environmental regulations, though their impact depends on the specific compounds and usage.
While effective for many tasks, anionic detergents are not universal. For example, they are incompatible with cationic fabric softeners (charge neutralisation reduces efficacy) and may not be ideal for some delicate fabrics or specialised industrial cleaning where non-ionic or cationic detergents are preferred.
Their excellent foaming ability and grease-removing properties make them effective for cleansing skin and hair. Common examples include sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES).
A cleaning agent in which the active part of the molecule carries a negative electrical charge when dissolved in water.
Anionic detergent is usually technical/scientific in register.
Anionic detergent: in British English it is pronounced /ˌæn.aɪˈɒn.ɪk dɪˈtɜː.dʒənt/, and in American English it is pronounced /ˌæn.aɪˈɑː.nɪk dɪˈtɝː.dʒənt/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
ANIONIC DETERGENT: A Negative Ion Cleans (ANIC) - remember the active part has a negative charge.
Conceptual Metaphor
CLEANING IS A BATTLE OF CHARGES (the negative ions repel dirt and oil, which are often negatively charged, creating a cleaning effect through charge repulsion).
