Contact Allergy to Castor Oil, but Not to Castor Wax [PDF]
Cosmetics, 2017 Ricinus communis (castor) seed oil (CAS 8001-79-4), a vegetable oil extracted from the seeds of Ricinus communis, is widely used in cosmetics and pharmaceuticals, and may be a cause of allergic contact dermatitis from these products. We present two patients with allergic contact dermatitis from cosmetics containing castor oil, in whom a correct ...
