General safety info about Propylene Glycol Isostearate from CIR
The Cosmetic Ingredient Review (CIR) Expert Panel reviewed the safetyof propylene glycol esters(PG esters) as used in cosmetics. These ingredients mostly function as skin-conditioning agents-emollient and as surfactants –emulsifying agent. The Panel reviewed relevant animal and human data related to theseingredients.The similar structure, properties, functions and uses of these ingredients enabled grouping them and using the available toxicological data to assess the safetyof the entire group. ThePanel mostly relied on data on the chemical componentsof these ingredients. The Panel concluded that these propylene glycolesters were safe as cosmetic ingredients in the practices of use and concentration described inthis safety assessment.
