1,2-Distearoyl-sn-glycero-3-phosphorylcholine (for injection) DSPC

The injection-grade DSPC supplied by V.A.T. is suitable for preparing liposomes and lipid nanoparticles (LNPs), serving as an excellent membrane material and helper lipid choice. DSPC has been extensively used in the development of liposomal drugs and LNPs, with relevant products already on the market and several liposomal drug products currently in clinical stages. Furthermore, DSPC can also be utilized as an excipient in formulations such as liposome-loaded microbubbles for contrast imaging, intravenous lipid microspheres, micelles, etc.

Although DSPC carries a slightly higher cost, its stability surpasses that of HSPC, making it a viable substitute;

As a helper lipid, it can expedite the structural transformation of LNPs within cells, thereby accelerating drug release.


DSPC is a fully synthetic phosphatidylcholine, featuring long-chain (18:0) saturated stearic acid inserted at the sn-1 and sn-2 positions. DSPC is also one of the most commonly used phosphatidylcholine derivatives in LNPs. It possesses a higher phase transition temperature (55°C), implying its capability to prevent premature degradation of LNPs within biological systems, thereby enhancing their stability. 

1,2-Distearoyl-sn-glycero-3-phosphorylcholine (for injection) DSPC Product Properties

DSPC has a well-defined structure, high purity, and stable physicochemical properties. When using cholesterol (CHO-HP) as an auxiliary emulsifier, different synthetic phospholipids can be chosen to meet the requirements of various drug components, enabling the preparation of liposomes with different characteristics.
