What is Octyldodecanol?
A branched, liquid fatty alcohol used as a non-greasy emollient and pigment carrier. It's a staple in lipsticks, foundations, and fragrance blends, and most sources consider it low-risk.
What to do if you're acne-prone
Source lists disagree on this one, which is why we flag it with a low rating rather than ignore it. Only the most reactive skin needs to avoid it outright.
Where this rating comes from
Our ratings consolidate two lineages: the original rabbit-ear comedogenicity assays published by James Fulton and colleagues (Fulton, Pay & Fulton, Journal of the American Academy of Dermatology, 1984; Fulton, Journal of the Society of Cosmetic Chemists, 1989), and the pore-clogger lists maintained by acne-specialist estheticians in the Face Reality lineage that refine those assays with decades of client observation. The source lists disagree about this ingredient, which is why its confidence is marked low.

Comedogenicity ratings come from published ingredient studies and esthetician-compiled lists. They are imperfect and formulation-dependent, and this page isn't medical advice. Reactions vary by skin, concentration, and the rest of the formula.
