Industrial Products

Stepan Company supplies a wide range of products for your lubricant formulation needs for applications like metalworking, including low-foaming emulsifiers, rust preventatives, additives for corrosion inhibition, extreme pressure additives and biocides. Our chemistries offer a variety of benefits for your metalworking formulation needs.

Stepan’s additives for metalworking can be used for the emulsification of components, act as coupling agents in soluble oils, semi-synthetic and synthetic fluids, and enhance metal cleaning performance.

Our phosphate esters can be used as a component in lubricants, gear and chain oils, metalworking fluids, hydraulic fluids and plasticizers. When used in metalworking fluids, our phosphate esters can function as extreme pressure agents in synthetic and semi-synthetic fluids.

Our amides can help tighten emulsions, improve rust prevention and provide lubricity.

Our range of hydrolytically stable esters can be used in high temperature applications and for improved lubrication properties. They can also act as a standalone chlorinated paraffin replacement or can be combined with phosphate esters for further formulation enhancements.

The textile industry has an ongoing demand for surfactant chemistries for applications throughout the textile production process. Stepan’s technical knowledge of textile and fiber chemistry makes us ideally positioned to supply the chemical ingredients used in the textile and fiber industry.

Commonly used surfactants for textile production:

• MAKON® 17R2 is a nonionic reverse EO/PO block copolymer that exhibits fast-breaking, low-foaming and defoaming properties.
• BIO-SOFT® D-40 is a sodium dodecylbenzene sulfonate that provides excellent detergency, foaming, wetting and emulsification properties. 
• AMMONYX® LO is a lauramine oxide that offers foaming, viscosity building, emulsification and lubrication in textile applications. 

Stepan supplies specific surfactant chemistries such as sulfates and sulfonates that are excellent foamers and are commonly used in Class A fire-fighting foams.

Commonly used surfactants for firefighting foam:

• BIO-TERGE® AS-40 is a sodium C14-16 olefin sulfonate that provides excellent viscosity, foam characteristics and mildness.
• STEOL® CA-460 is an ammonium laureth sulfate that provides excellent foaming and foam stability properties for industrial foaming applications.
• ALPHA FOAMER® is an ammonium alkyl ether sulfate that functions as a foaming agent for firefighting foam applications.

Stepan Company started its legacy by selling calcium chloride to control dust on Illinois roads. Dust particles can be very difficult to settle and may have a negative impact on health. That is why Stepan’s surfactants are used to control dust in tunneling, quarries and mining.

Commonly used surfactants for dust control:

• BIO-TERGE AS-40 is a sodium C14-16 olefin sulfonate that provides excellent viscosity, foam characteristics and mildness for dust control applications.
• BIO-SOFT D-40 is a sodium dodecylbenzene sulfonate that provides excellent detergency, foaming, wetting and emulsification properties.
