Stepan Company
Leading global manufacturer of surfactants and specialty chemicals.
Last updated August 31, 2026
Overview
Stepan Company is an American specialty-chemicals manufacturer headquartered in Northbrook, Illinois. Founded in 1932 by Alfred C. Stepan Jr., the company began as a small distributor of chemical products used to control dust on rural roads in Illinois. Its first operating base was reportedly a rented desk at Chicago’s North Pier Terminal. From that modest beginning, Stepan developed into a global supplier of chemical ingredients and intermediates used by manufacturers in consumer, industrial, agricultural, food, construction, energy, and pharmaceutical markets. The company’s portfolio is centered on surfactants, polymers, and related specialty materials. Surfactants help improve foaming, wetting, emulsification, dispersion, and cleaning performance, making them useful in detergents, shampoos, toothpastes, cosmetics, institutional cleaners, and industrial formulations. Stepan describes itself as the largest global merchant manufacturer of anionic surfactants, a category particularly important to cleaning and personal-care products. Its products are generally sold as ingredients or raw materials rather than directly to consumers under a prominent retail brand. Stepan’s broader product scope includes polyester polyols, phthalic anhydride, polymer systems, and other intermediates. These materials support polyurethane systems, coatings, adhesives, sealants, elastomers, powder-coating resins, rigid foams, and emulsion-polymerization applications. The company also supplies ingredients and chemical materials for agriculture, antimicrobial products, beverages, dietary supplements, flavors, food, nutrition, oilfield operations, pharmaceuticals, personal care, laundry, and household and institutional cleaning. A distinctive part of Stepan’s operations is its Maywood, New Jersey facility, acquired in 1959 when it was known as Maywood Chemical Works. The site is associated with the preparation of a decocainized coca-leaf extract used by The Coca-Cola Company. Stepan’s Maywood operation is described as the only commercial entity in the United States authorized by the Drug Enforcement Administration to import coca leaves. The imported leaves are processed so that the cocaine is removed; the non-narcotic extract is supplied for beverage production, while the recovered cocaine is sold to a pharmaceutical company for medicinal use. Stepan is publicly traded on the New York Stock Exchange under the symbol SCL. The company operates internationally and has approximately 2,000 employees according to the cited encyclopedia reference. Its business model is primarily business-to-business: it develops, manufactures, and supplies performance chemicals that customers incorporate into finished products and industrial processes. The company’s competitive position therefore depends on formulation expertise, manufacturing capacity, regulatory compliance, supply reliability, and the ability to tailor materials to application-specific performance requirements. Stepan remains an active company, with family continuity reflected in the involvement of Alfred C. Stepan Jr.’s grandson, F. Quinn Stepan Jr., in company leadership.
History
Stepan Company traces its origins to 1932, when Alfred C. Stepan Jr. began distributing chemical products intended to control dust on rural roads in Illinois. The enterprise initially operated from a rented desk at Chicago’s North Pier Terminal. This beginning positioned the company as a distributor and chemical-services business before it developed the manufacturing and specialty-materials capabilities associated with its modern identity. Over time, Stepan expanded beyond its initial road-dust business into the production and supply of industrial and specialty chemicals. Surfactants became a central part of the company’s portfolio. These materials are used to alter the behavior of liquids and mixtures, supporting cleaning, foaming, wetting, emulsification, and dispersion. Their applications reach across detergents, shampoos, toothpastes, cosmetics, household products, institutional cleaning, industrial cleaning, agriculture, and other formulated products. Stepan identifies itself as the largest global merchant manufacturer of anionic surfactants. The company also developed a broad polymer and chemical-intermediate business. Its products include polyester polyols, phthalic anhydride, specialty polymers, and materials used in emulsion polymerization. Polyester polyols and related systems are used in the manufacture of coatings, adhesives, sealants, elastomers, powder-coating resins, and rigid polyurethane foam. This range allowed Stepan to serve customers in construction, industrial products, energy, agriculture, food and nutrition, personal care, pharmaceuticals, and other sectors rather than depend on a single end market. A notable development in Stepan’s corporate history was the acquisition in 1959 of Maywood Chemical Works in Maywood, New Jersey. The facility became associated with the controlled importation and processing of coca leaves. It is described as the only commercial U.S. entity authorized by the Drug Enforcement Administration to import coca leaves. The plant produces a cocaine-free coca-leaf extract sold to The Coca-Cola Company for use in soft drinks. The cocaine removed during processing is sold to Mallinckrodt, a pharmaceutical company, for medicinal purposes. This activity is conducted within a tightly regulated legal and pharmaceutical framework and represents a specialized operation alongside Stepan’s larger specialty-chemicals business. Stepan subsequently became an international manufacturer and supplier, serving customers through a portfolio spanning surfactants, polymers, agricultural products, antimicrobial materials, food and beverage ingredients, nutritional products, oilfield chemicals, cleaning ingredients, and pharmaceutical-related materials. The company’s business is primarily business-to-business: its materials are incorporated into products made by other companies or used as inputs in industrial processes. Stepan is publicly listed on the New York Stock Exchange under the ticker SCL. The cited reference describes the company as having approximately 2,000 employees and identifies F. Quinn Stepan Jr., the founder’s grandson, as a company leader. The company remains active and headquartered in Illinois, with international operations and a product portfolio organized around performance, formulation, and process-chemistry requirements.

Products and positioning
A global business-to-business supplier of performance chemicals and specialty intermediates, with particular strength in surfactants and polymer-related materials.
SurfactantsCleaning and formulation ingredients
Stepan manufactures surfactants, including anionic surfactants, for use in detergents, shampoos, toothpastes, cosmetics, household cleaners, institutional products, industrial cleaning, agriculture, and other formulated goods. These materials can improve foaming, cleaning, wetting, emulsification, and dispersion. They are supplied mainly as industrial ingredients to manufacturers rather than as consumer products sold directly under the Stepan name.
Polyester polyols and polyurethane systemsPolymer materials
Stepan produces polyester polyols and related polyurethane systems used as raw materials in rigid foams, coatings, adhesives, sealants, elastomers, and powder-coating resins. These materials are designed for downstream manufacturers that need specific combinations of processing behavior and finished-product performance. They form an important part of Stepan’s polymer and construction-related chemical portfolio.
Phthalic anhydrideChemical intermediate
Phthalic anhydride is among the chemical intermediates identified in Stepan’s product scope. It is supplied for industrial uses and supports the production of downstream materials, including certain resins and polymer-related products. The reference material places this offering within Stepan’s broader industrial-products and specialty-chemicals activities.
Decocainized coca-leaf extractSpecialty botanical extract
The Maywood, New Jersey facility processes legally imported coca leaves to produce an extract with the cocaine removed. The cocaine-free extract is sold to The Coca-Cola Company for use in soft drinks. The operation is subject to U.S. controlled-substance regulation and is described as the only commercial U.S. operation authorized to import coca leaves.
