Sodium caprylate

Sodium caprylate (CAS 1984-06-1), also known as sodium octanoate, is the sodium salt of caprylic acid. It is used in pharmaceutical, food, and industrial formulations.

Where is Sodium caprylate used?

• Pharmaceuticals: stabilizer for human serum albumin solutions, protecting protein integrity
• Personal care: dispersion stability and mild surfactant activity in creams, lotions, and cleansers
• Food: emulsifying and buffering agent in processed formulations requiring controlled acidity
• Coatings and adhesives: catalyst or co-stabilizer in latex and polymer emulsion production
• It functions as an emulsifier, pH buffer, and stabilizing agent.

Good to know: It is relevant in protein-based systems where controlled dispersion and ionic balance are critical. USP and Ph. Eur. grades are primarily for parenteral and biopharmaceutical applications.
