Palmitoyl Isoleucine
What is Palmitoyl Isoleucine?
Palmitoyl Isoleucine is a synthetic lipoamino acid produced by esterifying palmitic acid, a common saturated fatty acid, with isoleucine, a branched-chain essential amino acid. This compound falls into the categories of emollients and surfactant-emulsifying agents in cosmetic formulations, especially anti-aging creams, serums, and lotions. It functions by depositing a protective lipid film on the skin to enhance softness and smoothness while stabilizing emulsions by reducing surface tension between oil and water phases. Its amphiphilic nature—having both hydrophilic and lipophilic parts—enables effective integration into diverse product textures. In skincare, it supports a more even skin appearance through conditioning effects, making it suitable for daily topical applications without compromising formula integrity.
