/aɪsəˈproʊpaɪl maɪrɪsteɪt/
Isopropyl Myristate is pronounced eye-suh-PROH-peyel-meye-ris-tayt (/aɪsəˈproʊpaɪl maɪrɪsteɪt/). It has six syllables (Is-o-pro-pyl My-ris-tate), with the stress on "pro". Isopropyl myristate is a cosmetic ingredient and solvent formed from isopropyl alcohol and myristic acid. It is used as an emollient and carrier fluid in skin-care formulations, valued for its light texture and skin-friendly feel. In pronunciation, it is typically treated as two compounds spoken together: isopropyl (three syllables) and myristate (three or four, depending on parsing).
verbIsopropyl myristate is a cosmetic ingredient and solvent formed from isopropyl alcohol and myristic acid.

In pronunciation, it is typically treated as two compounds spoken together: isopropyl (three syllables) and myristate (three or four, depending on parsing).
"Isopropyl myristate is commonly listed as an emollient in many lotions."
"Some cosmetics specify high purity isopropyl myristate for sensitive skin formulas."
"You’ll notice a smooth, non-greasy feel when isopropyl myristate is the active solvent."
Pronounce as /ˌaɪˌsoʊˈproʊ.paɪ məˈrɪ.steɪt/ (US). Stress is main on PRO in isopropyl and RĬ in myristate. Break it into two parts: isopropyl (eye-SOP-rohl) and myristate (muh-RIH-stayt). Start with a light extra syllable in the first word and emphasize the second word’s first syllable. See audio resources for listening practice; aim for a smooth transition between /paɪ/ and /mə/.
Common errors include: 1) stressing the wrong syllable in isopropyl (often PRO-pyl becomes the emphasis, not IS-o), 2) mispronouncing myristate as my-rist-ate with misplaced stress on -rist-, and 3) slurring the /r/ with a non-rhotic accent. Correction: place primary stress on the -proʊ in isopropyl, and on MYR- in myristate, keep /ə/ reduced in the first syllable of myristate, and articulate the final /eɪt/ clearly. Listen to IPA guides and practice with minimal pairs to lock in rhythm.
US tends to rhotically pronounce /ˈproʊ.pɚ/ and maintain clear /r/; UK may reduce rhotics slightly and lengthen vowels, with /ˈproʊˌpaɪ/ sometimes softened. AU often aligns with General American on rhotic treatments but may feature more clipped vowels; final -ate often realized as /eɪt/ in all. Focus on the -myristate segment: US/UK/AU share /ˈmɪ.rɪ.steɪt/ with subtle vowel shifts in /ɪ/ vs /ɪə/. Always keep final /teɪt/ crisp to avoid confusion with -stat or -sate.
Key challenges: long, multi‑syllable second word with stress on the first syllable of myristate; the 'isopropyl' cluster has a tricky /ˌaɪˈsoʊˌproʊ/ sequence with subtle vowel length. The combination of /ˈproʊ/ and /məˈrɪ.steɪt/ requires precise timing to avoid blending into something like 'isopropylmirthate.' Practice by isolating each segment, then linking at natural speaking speed, ensuring the -rate end stays as /steɪt/.
The phrase contains two ester-based terms that each carry distinct stress patterns. The first word isopro-pyl places primary stress on PRO, while myristate places stress on MRY- or MYR- depending on emphasis, with final -ate pronounced /eɪt/. The challenge is a smooth hinge between /paɪ/ and /mə/ and not letting the lip and tongue positions clash. Use clear syllable boundaries and a short pause between the two words on first utterance, then blend as you gain confidence.

US: maintain rhotic /r/ in both words; keep /proʊ/ strong with rounded lips, and ensure /ɪ/ in myristate is short. UK: possible non-rhoticity; keep /r/ subtle or silent before consonants; ensure final /eɪt/ is crisp. AU: similar to US but enhanced vowel clarity; avoid over-rounding lips in /proʊ/ to keep pace with the preceding /ɪ/ vl. IPA references anchor the vowels: /ˌaɪˌsoʊˈproʊ.paɪ məˈrɪ.steɪt/.
Isopropyl myristate combines two chemical components: isopropyl, derived from isopropyl alcohol (2-propanol), and myristate, the ester of myristic acid (tetradecanoic acid) with an alcohol. The term isopropyl comes from the hydrocarbon group isopropyl (a three-carbon substituent with formula C3H7) attached to a hydroxyl-bearing partner in esterification reactions. Myristate originates from myristic acid, itself historically derived from nutmeg (Piper nigrum) seed oil and other natural fats; the name derives from “myristic” from French myristique, reflecting its origin in animal and plant fats. The compound’s modern usage as a cosmetic emollient emerged in the mid-20th century with the expansion of ester-based solvents and moisturizer blends; IPM is a widely used glyceride-free ester due to its low viscosity, non-occlusiveness, and skin tolerance. The first published preparations citing IPM in cosmetic formulations appeared in the 1950s–1960s, aligning with the cosmetics industry’s shift toward synthetic esters to improve spreadability, absorption, and product stability. Today, isopropyl myristate is routinely referenced in ingredient lists as IPM, reflecting its role as a versatile solvent and conditioning agent.
