  • Applications

    Monostearyl citrate (CAS 1337-33-3) is a citrate ester used primarily as a plasticizer for polymers and coatings, improving flexibility and processability of materials. It also functions as a solvent or carrier in cosmetic and personal care formulations, providing emollient properties and a moderate polarity helping dissolve and distribute actives. As an intermediate in organic synthesis, it is commonly used in esterification-derived steps of citrate ester routes. In coatings, inks, and related formulations, it can serve as a plasticizing solvent to aid film formation. In adhesives and sealants, it is used as a compatible plasticizer or processing aid to enhance flexibility of the bond. Use is subject to local regulations and formulation limits.
