Potassium 2-ethylhexanoate

Potassium 2-ethylhexanoate (CAS 3164-85-0 ) is the potassium salt of 2-ethylhexanoic acid, supplied primarily as a catalyst precursor and processing aid across polymer, personal care, and specialty chemical applications.

It functions as a reactive metal carboxylate capable of delivering potassium ions in solution-phase reactions and formulation systems. In plastics and polymer processing, it acts as a catalyst or co-catalyst in polyurethane systems.

The compound promotes gel and cure reactions where controlled potassium delivery is required. Personal care formulators use it as a pH buffer and mild preservative-boosting agent in emulsion systems.

In these applications, it supports product stability without disrupting sensory profiles. In specialty chemical synthesis, it serves as a potassium source in carboxylate-exchange reactions and as a precursor for other catalysts.

Food and flavor applications leverage its acidulant and buffering capacity in systems requiring potassium fortification alongside mild organic acid character. It is typically supplied as a liquid solution for ease of use.

Concentration levels vary by application grade, with technical-grade material being the most common commercial form. Food-grade specifications are available for regulated applications requiring high purity standards.

Bulk supply in drums or IBCs is standard for industrial buyers. This chemical remains a versatile component for manufacturers seeking reliable potassium delivery in complex chemical formulations and industrial processes.
