What is Cetyl Acetate?
Cetyl Acetate is a synthetic emollient ester. An acetylated fatty ester often paired with acetylated lanolin. Named on comedogenic lists in the moderate range.
Where Cetyl Acetate shows up
You'll most often find Cetyl Acetate 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 Cetyl Acetate bad for acne-prone skin?
Cetyl Acetate 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: Cetyl Acetate'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: Cetyl Acetate 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.
Non-comedogenic alternatives
If you're avoiding Cetyl Acetate, these lower-risk ingredients serve a similar role and are gentler on pore-prone skin:
- Caprylic/Capric Triglyceride — rated 1/5 (Low risk).
- Squalane — rated 1/5 (Low risk).
