What a —/5 rating means
Because no dependable rating exists, judge Isopropyl Linoleate by how your own skin responds rather than by a number. The absence of a score is not the same as a zero — it simply means the ingredient has not been reliably tested on the classic comedogenic scale.
About Isopropyl Linoleate
It is a synthetic ester — an oil-and-alcohol reaction product engineered for a smooth, quick-absorbing slip. An isopropyl ester of linoleic acid, part of the same isopropyl-ester family as isopropyl myristate and isopropyl isostearate — both of which rate 5 on this grid. It is named on the CLEARSTEM and AcneClinicNYC pore-clogging ingredient lists, but neither publishes a 0-5 comedogenic score for it and no Fulton-derived table we cite carries one. We therefore leave it unrated rather than invent a number — treat the listing itself as the signal.
On a label it can read as Isopropyl Linoleate, Isopropyl Linolate — worth knowing when you scan an ingredient deck.
Isopropyl Linoleate in makeup and skincare
It is a workhorse of foundations, primers, sunscreens, and mascara, where a fast, silky slip sells the texture.
If you deal with fungal acne (malassezia folliculitis) rather than ordinary clogged pores, note that Isopropyl Linoleate 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.
Isopropyl Linoleate comedogenic FAQ
Is Isopropyl Linoleate comedogenic?
There is no established answer. No source we cite gives Isopropyl Linoleate a comedogenic rating, and a missing score is not the same as a 0. If you are acne-prone, watch how your skin responds.
What is the comedogenic rating of Isopropyl Linoleate?
Isopropyl Linoleate is unrated on the 0–5 comedogenic scale. Isopropyl Linoleate is one of 26 ingredients, out of the 216 in our dataset, that none of our cited sources gives a comedogenic number, so we leave it unrated instead of guessing.
Is Isopropyl Linoleate pore-clogging?
Without a published rating we cannot say either way. Its position on the ingredient list still matters: near the end of a label it is present in small amounts.
