01The question
Is Castor Oil (Ricinus Communis) safe in lipstick?
ClearedLipstick
A plant-derived oil from castor beans used extensively in lip and hair care. The CIR confirmed it is not a significant skin irritant, sensitizer, or photosensitizer. Well-tolerated with a long history of safe use; the main functional benefit is its high viscosity and excellent film-forming properties.
