Our Standard
Three principles behind every bottle.
90% ricinoleic acid
Ricinoleic acid is what people buy castor oil for, and most labels will not print how much is inside. Ours is lab tested and stated on every bottle.
Every number we print comes from lab tests on the batch in the bottle.
Small-batch crafted for meticulous quality control, not over-processed, not commercial grade.
