CIR Safety Review: Based on the physical and chemical properties of Xylene Sulfonic Acid, Ammonium Cumenesulfonate, Ammonium Xylenesulfonate, Calcium Xylenesulfonate, Potassium Cumenesulfonate, Potassium Toluenesulfonate, Potassium Xylenesulfonate, Sodium Cumenesulfonate, Sodium Toluenesulfonate, Sodium Xylenesulfonate and Toluene Sulfonic Acid the CIR Expert Panel considered that absorption of these ingredients following dermal exposure would be limited. The CIR Expert Panel also reviewed data indicating that these ingredients were not genotoxic, carcinogenic or developmental toxicants.

At concentrations greater than those used in cosmetics and personal care products, these ingredients can cause irritation to the skin. Therefore, the CIR Expert Panel concluded that these ingredients were safe for use in cosmetics and personal care products in the present practices of use and concentration when formulated to be non-irritating.
