What a 3/5 rating means
On the comedogenic scale, a 3 is the moderate midpoint: tolerated by many, a possible trigger for congestion-prone skin. That puts Cetyl Acetate squarely in the judgement-call zone, where your skin type and the product's formula decide the outcome.
This rating is disputed. Credible sources land on different numbers for Cetyl Acetate, so we publish the range (3) rather than a false single figure. When sources disagree this openly, your own experience carries real weight.
One thing the number cannot tell you is concentration. Ingredients are listed in descending order, so Cetyl Acetate near the end of a label is present in tiny amounts and matters far less than the same ingredient near the top.
About Cetyl Acetate
It is a synthetic ester — an oil-and-alcohol reaction product engineered for a smooth, quick-absorbing slip. An acetylated fatty ester often paired with acetylated lanolin. Named on comedogenic lists in the moderate range.
Cetyl Acetate in makeup and skincare
It is a workhorse of foundations, primers, sunscreens, and mascara, where a fast, silky slip sells the texture. Its irritancy is rated separately at 0/5, which is low.
If you deal with fungal acne (malassezia folliculitis) rather than ordinary clogged pores, note that Cetyl Acetate is among the fatty-acid or ester-type ingredients that community sources commonly avoid — a separate concern from its comedogenic score, and one with weaker evidence behind it.
Lower-rated alternatives to Cetyl Acetate
If you want a similar role with a friendlier comedogenic score, consider:
- Caprylic/Capric Triglyceride — comedogenic rating 1/5 (Low risk).
- Squalane — comedogenic rating 1/5 (Low risk).
Cetyl Acetate comedogenic FAQ
Is Cetyl Acetate comedogenic?
Moderately. Cetyl Acetate is rated 3/5 (moderate), the middle of the 0–5 scale: many people tolerate it, but it can contribute to breakouts on congestion-prone skin. Sources disagree on Cetyl Acetate, so the rating is less settled than most.
What is the comedogenic rating of Cetyl Acetate?
Cetyl Acetate has a comedogenic rating of 3/5 (moderate). Of the 190 ingredients in our dataset with a published rating, 39 rate higher than Cetyl Acetate, 97 rate lower, and 53 others share its 3/5. Among the 24 rated esters, 11 rate higher and none lower. The figure is drawn from 2 cited sources, listed on this page.
Is Cetyl Acetate pore-clogging?
It can be for some people. At 3/5, Cetyl Acetate is in the moderate band. How much it matters depends on concentration: near the top of an ingredient list it is a bigger factor than near the end. Comedogenic ratings come mostly from rabbit-ear assays and small human patch tests of the pure ingredient at high concentration, so they are a screening guide, not a prediction for your skin or a medical claim.
