Polyethylene Glycol (PEG) 1500 is a specific grade of polyethylene glycol, a polymer that plays a critical role in the pharmaceutical industry. Understanding its scientific properties is key to appreciating its extensive applications. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality PEG 1500, ensuring that pharmaceutical manufacturers have access to a reliable ingredient that meets stringent quality standards.

Scientifically, PEG 1500 is characterized by its average molecular weight, which falls between 1350 and 1650 g/mol. Its purity typically exceeds 99%, making it suitable for pharmaceutical formulations where purity is paramount. Key physical and chemical properties include a freezing point in the range of 42-48°C and a hydroxyl value of 70-80. These specifications are crucial for formulators who need predictable performance from their excipients. When considering pharmaceutical grade polyethylene glycol 1500, these details are essential for successful formulation.

The primary function of PEG 1500 in pharmaceuticals is as an excipient. Its hydrophilic nature and excellent solubility in water and various organic solvents allow it to act as a solvent, solubilizer, and viscosity enhancer. It is widely used in the formulation of ointments, creams, lotions, and suppositories, providing a stable and effective base for APIs. Furthermore, its role in drug delivery systems, such as enhancing the solubility of poorly absorbed drugs, significantly impacts therapeutic outcomes. The diverse pharmaceutical excipient uses highlight its broad applicability.

Beyond its excipient function, PEG 1500 is also a vital component in PEGylation, a process that modifies therapeutic proteins and peptides to improve their pharmacological properties. By attaching PEG chains, the circulation time of the drug in the body is extended, and its immunogenicity is reduced. This advancement is crucial for biologics and peptide-based therapies. If you are looking to buy PEG 1500 online for research or manufacturing, choosing a reputable PEG 1500 supplier China like NINGBO INNO PHARMCHEM CO.,LTD. ensures you receive material that meets these demanding requirements.
