Description

Caprylic acid (CAS 124-07-2 ), also known as octylic acid, is a saturated C8 fatty acid derived primarily from coconut and palm kernel oil. It functions as a pH regulator, emulsifier, and antimicrobial agent across food, pharmaceutical, and personal care manufacturing. In food production, caprylic acid is used as a flavoring agent and acidulant, with FEMA 2799 status supporting its use in dairy, baked goods, and beverage formulations. Pharmaceutical manufacturers use it as an excipient and stabilizer in lipid-based drug delivery systems. This versatile fatty acid is particularly effective for oral and topical formulations. Personal care formulators incorporate it into skin creams and hair products where it supports emulsion stability and acts as a conditioning agent. In metalworking and lubricant applications, it serves as a feedstock for ester-based lubricants and corrosion inhibitors. Caprylic acid is supplied as a colorless to pale yellow liquid that meets rigorous industrial requirements. Standard commercial grades include food-grade ( FCC ), pharmaceutical-grade ( USP / BP ), and technical-grade. Purity levels typically range from 98% to 99.5% to ensure consistent performance in sensitive chemical processes. Packaging options generally include drums and IBC containers, with bulk tanker supply available for high-volume industrial buyers. This ensures flexible logistics for manufacturers across the global chemical supply chain. Contact us for supply of Caprylic acid Request Quote
