What Is C13-14 Isoparaffin?
C13-14 isoparaffin is a petroleum-derived ingredient whose wax-like texture functions as an emollient (skin-softening lubricant), solvent and texture enhancer. It is often combined with film-forming agent polyacrylamide and emulsifier laureth-7 to create aesthetically pleasing gel formulations.\n\nC13-14 isoparaffin shows up in various skin care products from cleansers to lotions and everything in between. You can find this ingredient in makeup and hair care, too.\n\nThe Cosmetic Ingredient Review (CIR) Expert Panel reviewed relevant data on C13-14 isoparaffin and concluded it is safe in concentrations between 0.0001%-75%, as reported in their 2013 assessment of isoparaffins used in cosmetics.
