Castor Oil
Ricinus Communis (Castor) Seed Oil · Ricinus Communis · Ricinus Communis Seed OilBarrier
A thick, sticky oil used in lip balms and lash oils — and heavy on the face.
What it does
It’s mostly one unusual fatty acid, which makes it thick and gives it a slight sealing feel. It’s most common in lip balms, brow and lash oils, and body balms, where the heavy slip helps. On the face it can feel sticky, though animal tests rated it low for clogging.
