About JATROPHA MAHAFALENSIS SEED OIL

Derived from a tropical plant in the spurge family, this oil contains phorbol esters and curcins that make it a skin irritant and potential sensitizer; the seeds are notably toxic.

Detailed Analysis

Jatropha mahafalensis seed oil is a fixed oil expressed from a Madagascar euphorbiaceae species closely related to the widely studied Jatropha curcas. Like many Jatropha species, it contains toxic diterpenoids (phorbol esters) and ribosome-inactivating proteins (curcins) that can cause severe skin irritation, contact dermatitis, and systemic toxicity if ingested. Under EU cosmetic regulation EC 1223/2009, no specific authorization exists for this oil, and its phorbol ester content places it in the category of substances requiring caution; it is not listed in CosIng's positive list for safe cosmetic ingredients.
