Castor Oil
Castor Oil
A thick, glossy oil pressed from castor beans — unusually rich in a one-of-a-kind fatty acid that gives it slip, shine and serious staying power. Hover any measure to see where castor sits on the scale.
What it is
Castor oil is pressed from the seeds of the castor plant. It stands apart from almost every other oil because up to 90% of it is ricinoleic acid — a rare fatty acid found in barely any other plant — which is what gives castor its signature thickness, slip and glossy finish.
That density makes a little go a long way. It coats and conditions, lends body to balms and oils, and leaves a noticeable sheen — which is why it's a long-standing favourite in brow, lash, beard and hair formulas.
Quick Facts
The Plant & The Seed
The Castor Plant
A fast-growing, shrub-like plant cultivated across East Africa and India. Its spiky seed pods hold the glossy, bean-like seeds that give the oil its name.
The Seeds
The mottled seeds are pressed to release castor's thick, pale oil. Cold-pressing keeps it gentle, while careful refining removes the seed's naturally occurring irritants.
The Compound Profile
Castor is defined by one extraordinary fatty acid that almost no other oil carries in quantity. The typical breakdown looks like this:
