Introduction to Stearic Acid in Pharmaceuticals
Stearic acid is a versatile and essential excipient in the pharmaceutical industry, serving multiple critical functions in drug formulations. It acts as a lubricant, binder, emulsifier, and stabilizer, making it a cornerstone in the production of tablets, capsules, creams, and ointments[1][3].
Pharmaceutical Applications of Stearic Acid
Lubrication and Binding
Stearic acid is primarily used as a lubricant in tablet and capsule manufacturing, ensuring smooth compression and ejection from die cavities. It prevents the sticking of granules or powder to tablet punches and dies, enhancing tablet hardness and reducing issues like capping and lamination[1][3].
Emulsification and Solubilization
Stearic acid facilitates the incorporation of hydrophobic drugs into water-based formulations, improving their stability and enhancing drug delivery. It also forms micelles and liposomes, which are nano-sized carriers that enhance the solubility and bioavailability of water-insoluble drugs[1][3].
Targeted Drug Delivery
Researchers are exploring stearic acid for its potential in targeted drug delivery. By modifying the stearic acid molecule, it can be used to create specialized carriers that target specific cell receptors and deliver drugs to designated cells or tissues[3].
Market Size and Growth Projections
Global Market Value
The global stearic acid market is projected to grow significantly, from an estimated value of USD 40.5 billion in 2024 to over USD 71.3 billion by 2034, with a strong compound annual growth rate (CAGR) of 7.6%[2][5].
