Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that propylene glycol esters, including Soybean Oil Propylene Glycol Esters, are safe for use in cosmetic ingredients. While the ester itself is considered safe, propylene glycol, a component of this ester, has been associated with instances of irritation and contact dermatitis, even at concentrations as low as 2%, when not optimally formulated for non-irritancy. The FDA classifies propylene glycol as 'generally recognized as safe' (GRAS) for various applications including food and cosmetics.
