5/10

Concern level

Moderate concern

Petroleum resins are a family of synthetic hydrocarbon resins derived from petroleum feedstocks. In cosmetics they are used mainly as film-formers, viscosity modifiers, and tackifiers rather than as skin-active treatment ingredients. They are typically insoluble in water and are used in small amounts in anhydrous or solvent-based systems.
