What is Isopropyl Neopentanoate?
Isopropyl Neopentanoate is a synthetic emollient ester. An isopropyl ester emollient repeatedly flagged as comedogenic in the moderate range.
Where Isopropyl Neopentanoate shows up
You'll most often find Isopropyl Neopentanoate in lotions, sunscreens, primers, and colour cosmetics, where it adds a smooth, non-greasy slip. Separately from clogging, its irritancy is rated 0/5 — low, so it's unlikely to sting or sensitise on its own.
Is Isopropyl Neopentanoate bad for acne-prone skin?
Isopropyl Neopentanoate sits in the grey zone. Plenty of people tolerate it well; those who break out easily may prefer to keep it low on their ingredient lists.
Worth flagging: Isopropyl Neopentanoate's rating is disputed. Credible sources land on different numbers, which is why we show a range rather than a single score — and why your own experience is the best tiebreaker.
Note for fungal-acne (malassezia) sufferers: Isopropyl Neopentanoate is commonly avoided in fungal-acne routines, since it falls into the fatty-acid or ester families the yeast can feed on. The evidence there is looser than for comedogenicity — see our fungal-acne checker for context.
