Core Functions
Inhibits intermolecular hydrophobic aggregation of proteins, preventing thermal denaturation and freeze-induced damage. Often formulated with Sodium Acetyltryptophanate for injectables such as Human Albumin and Immunoglobulins.
Disrupts bacterial cell membrane integrity, exhibiting strong inhibitory effects against fungi and Gram-positive bacteria. Applied in topical antifungal medications, preservative systems, and oral care products.
Amphiphilic structure (hydrophilic sodium carboxylate + hydrophobic C8 alkyl group) effectively lowers interfacial tension. Functions as an O/W emulsifier, dispersant, and solubilizer, featuring low foam and easy rinse-off.
Weakly alkaline; used for fine-tuning formulation pH to enhance system stability.

Frequently Asked Questions
Sodium Caprylate appears as white crystals or crystalline powder with an assay of 99.0~101.0%. It has a pH value of 8.0~10.5, water content of ≤3.0%, heavy metals (Pb) of ≤5ppm, and chromatographic purity with no more than 0.3% of any single impurity and no more than 0.5% of total impurities.
It serves as a pharmaceutical core stabilizer by inhibiting the intermolecular hydrophobic aggregation of proteins, which prevents thermal denaturation and freeze-induced damage. It is frequently formulated with Sodium Acetyltryptophanate for biological injectables like Human Albumin and Immunoglobulins.
Antimicrobially, it disrupts bacterial cell membrane integrity, showing strong inhibitory effects against fungi and Gram-positive bacteria. As a surfactant, its amphiphilic structure lowers interfacial tension, functioning as a low-foam, easy-to-rinse O/W emulsifier, dispersant, and solubilizer.
Sodium caprylate (sodium octanoate) is used because salts possess greater solubility than the higher acids themselves, allowing for better pH adjustment in cultivation mediums, such as when selecting and cultivating bacteria that decompose octanoic acid.
It is packaged in 25kg fiber drums lined with PE. For storage, it must be kept in a cool, dry, and sealed environment at room temperature, ensuring it remains moisture-proof and protected from strong oxidants.
