What a —/5 rating means
Because no dependable rating exists, judge Laureth-7 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 Laureth-7
It is an emulsifier, the ingredient that keeps a product's oil and water phases from separating. A lauryl alcohol ethoxylate used as a mild emulsifier and solubiliser. Its close relatives on this grid diverge sharply — laureth-4 rates 5 and laureth-23 rates 3 — so chain length matters a great deal in this family. It is named on the CLEARSTEM pore-clogging ingredient list, but that list does not publish 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 Laureth 7, Laureth-7 — worth knowing when you scan an ingredient deck.
Laureth-7 in makeup and skincare
It quietly stabilises most cream foundations, lotions, and moisturisers.
If you deal with fungal acne (malassezia folliculitis) rather than ordinary clogged pores, note that Laureth-7 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.
