Irving-based NCH and Wilmington, Delaware-based Solenis have agreed to merge in a deal in which Solenis will acquire 100% of NCH stock, creating “a more diversified, customer-centric provider of water and hygiene solutions,” the companies said.
NCH was originally founded in Dallas in 1919 by Milton P. Levy as National Disinfectant Company. Under the terms of the merger, the Levy family will become the largest minority shareholder in Solenis. The transaction’s further financial terms were not disclosed.

A leading provider of cleaning, water treatment, plumbing, and other maintenance solutions for industrial and commercial clients, NCH has 6,000 employees providing water treatment and industrial solutions to customers through 24 manufacturing plants and 76 distribution centers across 48 countries.
“Our grandfather started NCH over a century ago to provide customers with the highest quality solutions, served by the best trained professionals,” the Levy family said in a joint statement. “Since then, our family and associates have diligently pursued that vision and merging with Solenis is the best way to take a great business and make it even better. We’re committed to our associates and customers and know they will continue to thrive with Solenis.”
The transaction is expected to close by the end of the year. Solenis and NCH will continue to operate as independent companies until the transaction is complete, the companies said.

‘Better together’
Solenis is a global provider of water and hygiene solutions. It was acquired by Platinum Equity in 2021.
“The merger presents a unique opportunity to unite our complementary businesses. By leveraging Solenis’ global reach and NCH’s established presence in the middle market, we can enhance the customer experience through Solenis’ 360 approach,” Solenis CEO John Panichella said in a statement. “Joining forces creates a more diversified business with increased scale, an expanded global footprint, and superior customer service capabilities. Together, the newly combined company will provide attractive cross-selling opportunities, including meeting the increasing customer demand for sustainable and digital solutions.”
Chris Wright, president of NCH Global Chemical said the merger improves both companies.
“Solenis and NCH will be better together,” Wright said. “Joining forces will amplify opportunities for our associates around the world. We’re excited to merge with a truly great company, which allows us to better serve our customers through a broader product and service offering.”
