Stepan Company will shutter its Fieldsboro, NJ site in response to continued lower demand in commodity surfactants used in the production of laundry detergents. Additionally, select assets at Stepan’s Millsdale, IL and Stalybridge, UK facilities will be decommissioned, the company announced yesterday.

The actions are part of the company’s “Project Catalyst” plan. Officials expect the plan to deliver approximately $100 million in pre-tax savings over the next two years as it “optimizes” its global manufacturing footprint through consolidation of volume into more efficient and modern assets.

The Fieldsboro closure and the Illinois and UK drawdowns are expected by mid-2026. The operations will be consolidated into the company’s existing network, which Stepan says will create a more cost-efficient, streamlined structure while maintaining ongoing supply for customers.

Site Optimization Efforts

At the end of 2025, Stepan announced the sale of its Philippines and Lake Providence sites. 

The company said it will evaluate additional footprint optimization initiatives as it looks to “further strengthen its competitive position.”

“Project Catalyst is a comprehensive plan designed to further optimize our asset base and create a more productive and agile organization to enable growth,” said Luis E. Rojo, president and CEO. “Project Catalyst is designed to partially offset inflationary pressures and other headwinds, while enabling us to maintain the resources and flexibility needed to deliver exceptional service and value to our customers. These anticipated savings will also support targeted and strategic investments to boost growth and strengthen Stepan’s competitive edge.”

In December, Stepan held ribbon cutting for its alkoxylation facility in Pasadena, TX. The project represented the largest capital investment in the company’s history.

The Pasadena facility expands Stepan’s alkoxylation capacity with both ethoxylation and propoxylation capabilities, and supports an annual output of 75,000 metric tons.
