Sodium caprylate

Sodium caprylate (CAS 1984-06-1 ), also known as sodium octanoate, is the sodium salt of caprylic acid used across pharmaceutical, food, and industrial formulations. It functions primarily as an emulsifier, pH buffer, and stabilizing agent.

This chemical is particularly relevant in protein-based systems where controlled dispersion and ionic balance are critical. In pharmaceutical manufacturing, it acts as a stabilizer for human serum albumin solutions, protecting protein integrity.

The compound ensures stability during heat treatment and storage of sensitive biological materials. Personal care formulators incorporate it into emulsion systems such as creams, lotions, and cleansers for better performance.

In these cosmetic applications, it contributes to dispersion stability and mild surfactant activity. Food-grade applications include its use as an emulsifying and buffering agent in processed formulations requiring controlled acidity.

In coatings and adhesive systems, it functions as a catalyst or co-stabilizer in latex and polymer emulsion production. Sodium caprylate is supplied as a white to off-white powder or crystalline solid for various uses.

It is available in pharmaceutical-grade specifications, including USP and Ph.Eur. grades, primarily for parenteral and biopharmaceutical applications. These standards ensure high purity for medical use.

Food-grade and technical-grade material is also commercially available to serve formulation and industrial end uses. This versatility makes it a staple ingredient for manufacturers across multiple global sectors.
