Safety Information

The safety of Decyl Oleate, and Isodecyl Oleate, has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that Decyl Oleate and Isodecyl Oleates were safe for use in cosmetics and personal care products. In 2001, as part of the scheduled re-evaluation of ingredients, the CIR Expert Panel considered available new data on Decyl Oleate and Isodecyl Oleate and reaffirmed the above conclusion.

CIR Safety Review: Studies have shown both Decyl Oleate and Isodecyl Oleate to possess low acute oral toxicitt. Single application dermal and eye studies have shown these materials at 100% concentrations produce little or no irritation. Daily skin applications of 15% or 100% for 60 days produced a moderate degree of irritation with both Decyl and Isodecyl Oleate. Neither of the ingredients was found to be a sensitizer when tested at concentrations of 15%. Based on the available information, the CIR Expert Panel concluded that Decyl Oleate and Isodecyl Oleate were safe at the reported use concentraitons.
