Description
Pelargonic acid (CAS 112-05-0) is a straight-chain saturated fatty acid derived from natural oils, commercially known under names including Nonoic acid, C9 acid, and FEMA 2784. It carries no E-code designation and is identified under EC number 203-931-2 with the molecular formula C9H18O2.
In personal care formulations, pelargonic acid functions as an emulsifier and emulsion stabilizer by reducing interfacial tension between oil and water phases, improving texture consistency. In lubricant and metalworking applications, it acts as a pH buffer and corrosion-control agent, while in food-contact and flavoring contexts it is referenced under FEMA 2784 as a permitted flavoring substance.
Pelargonic acid is supplied in liquid form and is available in technical and food-grade specifications. It falls under REACH regulation and is classified under HS code 29159080 for EU customs purposes. Packaging formats typically include drums and IBC containers; buyers should confirm grade-specific documentation including SDS and certificate of analysis.
