Chemithon

What Chemithon does

Chemithon Corporation is a privately held engineering and manufacturing company founded in 1954 in Seattle, Washington, specializing in sulfonation and sulfation process technology. The company designs, fabricates, and services complete plant systems for producing surfactants used in detergents, shampoos, toothpaste, and lubricating oil additives, anchored by its proprietary Annular Falling Film Reactor, Multi-Tube, Impact Jet, and Turbo-Tube reactors. It also supplies environmental systems for power generation (flue gas conditioning, SafeDeNOx urea-to-ammonia NOx reduction), custom ASME-certified fabrication (U/UM/R stamps), pilot plant R&D services, and a Surface Finishing division serving plating and printed circuit board industries. The company holds over 20 patents and claims at least 62% of the global market for heavy alkylate sulfonation plants, with more than 450 operating plants installed across consumer products, petrochemical, energy, and chemical manufacturing enterprises.

Chemithon generates revenue through one-time capital equipment sales (complete plants and individual reactors ranging from 5 kg/hr to over 20 MT/hr capacity), recurring spare parts supply, contract technical services (audits, training, troubleshooting), and contract pilot plant R&D for feedstock qualification. Its go-to-market combines direct sales from Seattle headquarters with a global alliance network: Mitsui Plant Systems in Japan (energy/petrochemical), Binacchi & Company in Italy (soap/glycerine/detergent plants in 100+ countries), and previously Trivedi Group in India. Enterprise customers include Procter & Gamble, Colgate-Palmolive, Lubrizol, Chevron, Dow, Shell, Stepan, Boeing, and multiple US utilities. The company has remained privately held and family/founder-led (Burton Brooks remains Chairman) since inception, with no disclosed funding rounds, M&A activity, or IPO.
