Description
Caprylic Acid (CAS 124-07-2) is a straight-chain saturated fatty acid derived from coconut and palm kernel oil, commercially available under trade names including Neo-Fat 8 and Lunac 8-95, and referenced under FEMA 2799. It is also abbreviated as C8 Acid or C8:0 Acid in fatty acid nomenclature.
In personal care formulations, Caprylic Acid functions as an emulsifier by reducing interfacial tension between oil and water phases, improving droplet stability in creams and lotions. In food and pharmaceutical manufacturing, it serves as a pH buffer and antimicrobial agent, where its medium-chain structure enables membrane disruption in microbial cells at controlled concentrations.
Caprylic Acid is supplied in food-grade (FCC compliant) and pharmaceutical-grade (Ph.Eur. compliant) specifications, with REACH registration in place for EU supply. Standard packaging includes intermediate bulk containers and drums. Buyers should confirm grade suitability against application-specific regulatory requirements.
