Application

Palmitic Acid, FCC, serves a versatile role across various industries due to its properties as a saturated fatty acid with a 16-carbon backbone. Predominantly found in palm oil, as well as in butter, cheese, milk, and meat, it is a principal component of a mixture of solid organic acids primarily composed of palmitic acid with varying amounts of stearic acid. In industrial applications, it acts as a lubricant, binder, and defoaming agent, and is widely employed in the production of soaps and cosmetics. The saponification of palm oil with sodium hydroxide produces sodium palmitate, a component often found in processed foods for its textural benefits. Beyond its use in food and beauty products, palmitic acid is also utilized in the production of cetyl alcohol, contributing to the formulation of detergents. Additionally, its utility extends to the pharmaceutical realm, where it is involved in oral and topical formulations, as well as in the development of sustained-release drug delivery systems. Notably, it plays a crucial role in the synthesis of paliperidone palmitate, a long-acting antipsychotic medication used to treat schizophrenia, by serving as a carrier medium for intramuscular injections.
