The efficacy of many pharmaceutical compounds is often limited by their poor solubility and stability in biological environments. Distearoylphosphatidylethanolamine (DSPE), CAS 1069-79-0, a phospholipid renowned for its unique amphiphilic nature, offers a powerful solution to these challenges. As a dedicated supplier and manufacturer of high-purity DSPE, we are at the forefront of providing essential materials that drive innovation in drug formulation.

DSPE's molecular structure features a hydrophilic head group (phosphoethanolamine) and two hydrophobic tails (stearoyl chains). This dual nature allows it to self-assemble into various structures, most notably liposomes and micelles. In liposomes, DSPE forms a stable bilayer membrane, effectively encapsulating hydrophilic drugs within the aqueous core and lipophilic drugs within the lipid bilayer. This encapsulation significantly improves the solubility of poorly soluble drugs, making them bioavailable for therapeutic use. For research scientists and product formulators, understanding these scientific principles is key to leveraging DSPE's full potential.

The saturated nature of the stearoyl chains in DSPE imparts a higher phase transition temperature compared to phospholipids with unsaturated fatty acids. This characteristic contributes to the thermal stability of liposomes, preventing premature drug leakage and maintaining the integrity of the delivery system. When you buy Distearoylphosphatidylethanolamine from a trusted manufacturer in China, you are securing a component that offers enhanced stability, a critical factor for drugs requiring long shelf lives or controlled release mechanisms. We ensure our DSPE offers a minimum purity of 97%, vital for these precise applications.

Furthermore, DSPE plays a crucial role in creating PEGylated liposomes. By conjugating polyethylene glycol (PEG) chains to the DSPE headgroup, the resulting DSPE-PEG conjugate can be incorporated into liposomes. The hydrophilic PEG corona effectively shields the liposome from recognition by the immune system, significantly prolonging its circulation time in the bloodstream. This 'stealth' effect is a cornerstone of many targeted drug delivery strategies. For those looking to buy DSPE for liposome formulation, consider us for your reliable supply and competitive DSPE price.

The application of DSPE extends to other nanocarrier systems and even cosmetic formulations, where its emulsifying properties are highly valued. As a leading pharmaceutical excipient supplier, we are committed to supporting scientific endeavors by providing access to high-quality DSPE. We invite R&D scientists to inquire about our products and to request a sample to experience the scientific advantage DSPE offers firsthand. Partner with us to advance your drug delivery innovations.
