This product is a widely used industrial solvent that is virtually odorless and has minimal acute and chronic toxicity. Exxon Isopar L delivers narrow boiling ranges for consistent as well as predictable drying rates and easier recovery and recycling. Exxon Isopar L is fully compatible with metals and is compatible with polymeric materials that won’t damage most plastics and elastomers. Exxon Isopar L has high OELs (Occupational Exposure Limits) for safer operations and lower exposure risks compared to conventional solvents. It also gives you the choice of boiling ranges and flashpoints to create a tailored cleaning solution in a wide range of evaporation rates.


  • Virtually odorless
  • Low surface tension ensures that fluid gets to areas that other fluids cannot reach
  • Compatible with metals and polymeric materials that won’t damage most plastics and elastomers
  • Narrow boiling ranges for consistent and predictable drying rates and easier recovery and recycling
  • High product consistency and chemical stability for dependable performance after repeated use and recycling


Use Exxon Isopar L as an industrial solvent to:

  • Cleaning (dry cleaning and industrial cleaning)
  • Coating (aluminum paste, decorative coating, mold release agent)
  • Extraction process (oilfield and refinery chemicals, fuel additives)
  • Cleaner and polisher (lap oil, liquid vaporizer, portable heater)
  • Metalworking (rust preventive, forming fluid, evaporative oil)
  • Printing (blanket wash, liquid toner)
