Sulfate-free checker
Paste an ingredient list. We read every name and tell you which ones fall in the sulfate family under INCI naming rules — and why. No ratings, no verdict on the product, no advice.
What counts as sulfate here
Sulfate here means the sulfate and sulfonate surfactant family — sodium lauryl sulfate, sodium laureth sulfate, ammonium lauryl sulfate, olefin sulfonates, sulfosuccinates. Plain mineral sulfate salts (magnesium sulfate, zinc sulfate) are not surfactants and are not flagged.
This is a name check on the list you paste: each ingredient name is tested against the naming rules above. It cannot see trade names, undeclared components, or a brand's own definition of “sulfate-free” — that claim is theirs. If a name is missed or wrongly matched, tell us.
Looking for pore-cloggers instead?
The main checker matches each ingredient against published comedogenicity ratings with their source and confidence tier. The two checks are independent: a list can match none of the rules on this page and still contain a 5/5 ingredient, or the reverse.
