Solenis

Solenis is a global specialty chemicals company formed through the merger of Solenis, Diversey, and NCH Corporation, headquartered in Wilmington, Delaware, with over a century of combined water treatment experience. The company serves five major sectors—water treatment, pulp and paper, industrial processing, institutional cleaning, and food and beverage—through an integrated portfolio of chemical programs and digital monitoring platforms. Water treatment product lines include Biosperse XD3899 microbiocide for biofilm control, Zalta antiscalants for scale prevention, OnGuard 2-plus controllers for real-time monitoring of corrosion and fouling, and ClearPoint biofilm detection systems. The OPTIX Applied Intelligence platform and Solenis Cloud deliver predictive analytics, while the Internet of Clean provides IoT-based facility management. Pulp and paper offerings span barrier coatings, defoamers, sizing agents, strength additives, and the OptiFill filler optimization system. Through the Diversey acquisition, Solenis expanded into commercial cleaning with TASKI floor machines, LESSEAU solid hand wash, and infection prevention solutions. Food and beverage processing products include CIP chemicals, membrane cleaners, and farm hygiene programs. The company protects over $10 trillion in annual spend across its client base and serves industries including oil and gas, mining, data centers, life sciences, and municipal water.
