The Expert Panel for Cosmetic Ingredient Safety (Panel) reviewed the safety of polyenes, which are reported to function in cosmetics primarily as film formers and viscosity increasing agents. The Panel reviewed relevant data related to these ingredients, not inggaps in the available safety data for some of the polyenes in this safety assessment. The data available for many of the ingredients are sufficient and can be extrapolated to support the safety of the entire group because of the similarities in the chemical structures, chemical properties, use concentrations, and reported functions across the group. The Panel concluded that polyenes were safe in cosmetics in the present practices of use and concentration described in this safety assessment.
