Stearic Acid
C18H36O2
Stearic acid is a saturated fatty acid used to formulate solid lipid nanoparticles (SLNs). SLNs are advantageous due to their high stability, biocompatibility, and enhanced circulation of encapsulated therapeutic payload. Stearic acid, when combined with a surfactant, can be used to formulate SLNs to improve drug efficacy.
