Triclosan is pronounced /ˈtrɪ.kloʊ.zən/ (US) or /ˈtrɪ.kləʊ.zən/ (UK/AU). The primary stress falls on the first syllable. Break it into four parts: TRI /-klo- / -san. Start with a short, crisp 'tri' then a rounded 'klo' with a long o, finishing with schwa + n. Mouth positions: lips neutral to rounded for /oʊ/; tongue high-mid for /ɪ/; a light, soft ‘z’ before final ‘ən’.
Common errors: misplacing stress (saying tri-CLO-san with incorrect emphasis), vowel drift in the /oʊ/ or /ə/ sounds, and pronouncing /zən/ as /sən/. Correction: keep primary stress on the first syllable, use a clear /oʊ/ or /əʊ/ for the second vowel depending on accent, and ensure the final is a voiced z followed by a schwa and nasal /n/.
In US, the second vowel typically has a strong /oʊ/ as in /ˈtrɪ.kloʊ.zən/. In UK/AU, you’ll hear /ˈtrɪ.kləʊ.zən/ with a less tense onset in the second syllable and a longer /əʊ/ diphthong. The first syllable remains unstressed relative to the rest, but the vowel quality can shift slightly toward a lax /ɪ/ in rapid speech.
Two main challenges: the combination of /klo/ and /zən/ can cause mishearing of the middle consonant cluster, and the /ɪ/ vs /ɪə/ or /i/ vowel quality can vary with accent. The presence of a final /zən/ cluster can be mistaken for /zən/ vs /zən/ with a devoiced /z/. Focus on the clear /klo/ onset and the final /zən/ to lock in the sound.
Triclosan’s unique feature is the stressed /ˈtrɪ/ syllable and the diphthong in /loʊ/ (US) vs /ləʊ/ (UK/AU). The combination of an affricate-like /tr/ onset, a rounded second syllable /kloʊ/ or /kləʊ/, and a final voiced /zən/ makes it a multi-phoneme word where precise tongue position matters for a smooth transition between syllables.

Triclosan derives from the combination of tri-, meaning three, and -closan, linked to chlorine-based antiseptic compounds in earlier nomenclature. The root forms reflect a tri-substituted phenoxyphenol structure used in early antimicrobial chemistry, with the 'tri-' prefix signaling three functional groups or chlorinated substitutions. First developed in the 1960s for medical and consumer use, triclosan was marketed in the 1970s and gained widespread presence in household products by the 1990s. Its name entered scientific and regulatory discourse as its environmental and health effects became research foci, particularly regarding endocrine disruption, bioaccumulation, and antibiotic resistance concerns. While the chemical name remains stable, public understanding has shifted from a general antiseptic to a regulated compound with usage restrictions in many regions. The term is now often encountered in policy documents, safety assessments, and toxicology reports, reflecting its controversial status rather than a neutral consumer product label.
