Interactions

incompatible with: No well-established ingredient incompatibilities are documented in the sources reviewed., Use caution in formulas for highly sensitive or allergy-prone users because sensitization is possible.

Risks & Warnings

Primary concern is potential skin sensitization/allergic reaction in susceptible individuals; PubChem lists H317 (may cause an allergic skin reaction). As with other heavy castor-oil-derived emollients, it may feel occlusive on very acne-prone or fungal-acne-prone skin, though robust comedogenic data are lacking.
