What is Lanolin Alcohol?
Chemically, Lanolin Alcohol is a lanolin-derived ingredient (from sheep's wool). The alcohol fraction of lanolin, used as an emulsifier and emollient. Low-moderate comedogenicity at 2/5.
You may see it on labels as Lanolin Alcohol, Wool Alcohol, Sheep Alcohol, so it can hide under more than one name in an ingredient list.
Where Lanolin Alcohol shows up
Lanolin Alcohol is commonly formulated into lip products, rich balms, and heavy moisturisers. Separately from clogging, its irritancy is rated 0/5 — low, so it's unlikely to sting or sensitise on its own.
Is Lanolin Alcohol bad for acne-prone skin?
That low score makes Lanolin Alcohol a reasonable choice even for acne-prone skin. As always, individual reactions vary, but it is not a likely cause of clogged pores.
Note for fungal-acne (malassezia) sufferers: Lanolin Alcohol is commonly avoided in fungal-acne routines, since it falls into the fatty-acid or ester families the yeast can feed on. The evidence there is looser than for comedogenicity — see our fungal-acne checker for context.
