Sodium 2-ethylhexanoate

Sodium 2-ethylhexanoate (CAS 19766-89-3) is the sodium salt of 2-ethylhexanoic acid; a catalyst and drying promoter for industrial coating and polymer systems.

Where is Sodium 2-ethylhexanoate used?

• Coatings and alkyd resins: drying catalyst
• Solvent-borne and waterborne formulations: co-drier accelerating oxidative crosslinking
• Adhesives and sealants: cure accelerator for silicone and polyurethane systems
• Plastics and polymers: catalyst or stabilizer additive during compounding and polymerization
• Personal care: pH buffer and preservative booster in emulsion systems
• It functions as a metal-free carboxylate catalyst, an alternative to heavy-metal-based driers and cure accelerators.

Good to know: Metal-free carboxylate catalyst, an alternative to heavy-metal-based driers and cure accelerators. Sodium carboxylate salts provide compatibility with sensitive active ingredients in these specialized formulations.

Commercial specifications

• Liquid solution, concentrations commonly 50% to 95% in water or hydrocarbon solvents
• Specialty grades with tighter purity specifications for personal care and food-contact applications
