Products and markets

Distributors of utilities for consumer use are required by law to odorize natural gas and propane to assist in detecting possible leaks and lessening the risk of natural gas explosions. Therefore, Arkema Odorants offers product lines for use in both natural gas and propane/butane, including various blends of SPOTLEAK®, EthylMercaptan (EM), and THT (TetraHydroThiophene).

Another Arkema Odorants product, Mercaptan Assassin™ ESD, is used to clean up mercaptan spills, treat empty drums, and remove mercaptan from fabric or clothing. Mercaptan Assassin™ ESD digests mercaptans, proteins, carbohydrates, cellulose, fats, oils, uric salts, and grease. It is particularly effective for foul odor "emergencies" where both instant and long-lasting odor control are desired. Mercaptan Assassin™ ESD is safe to be used around people, domesticated animals, plants, and marine life.

A compatible product, Mercaptan Assassin™ AOT, is used to treat airborne odors. With just one or two mists, even the most offensive odors are cleared away, leaving a pleasant citrus smell.

Key figures for 2018

Number of employees



Local economic impact (payroll/utility/property taxes paid annually)


Investment in health, environment, and safety


  • Upgraded equipment to eliminate TSS permit exceedances at stormwater outfall.
  • Upgraded delivery fleet to reduce sources of leaks.
  • State-of-the-art "closed-loop" delivery system utilized. In traditional "flared" delivery, excess vapors are burned off creating sulfur dioxide, rising environmental concerns, and resulting in a powerful aroma. Odor-Tech's closed-loop delivery system eliminates excess vapors and results in a safer, odor-free, delivery.
  • Each of the storage tanks on the Pineville site is surrounded by a secondary, welded-steel containment structure that can hold the entire contents of the tank in the event of an emergency.
