Palmitic acid CAS#57-10-3

Basic Information

Palmitic acid

Palmitic acid is an odorless white crystalline or flaky fatty acid. It is insoluble in water but dissolves in ethanol, ether and chloroform, with a moderate melting range that supports melt processing and formulation. As a naturally occurring fatty-acid raw material, it is used in chemical synthesis and in formulations requiring a stable long-chain fatty component. Its documented source profile includes both plant and animal materials.
