Polyethylene glycol 4000 [25322-68-3]

Polyethylene Glycol 4000 is a versatile solvent that brings clarity to complex formulations. Its molecular structure, comprising a hydrophilic backbone and hydrophobic branches, allows it to dissolve a wide array of substances. In its white powder form, PEG 4000 is an essential tool for researchers and manufacturers seeking precision and reliability.

Why This Format Works Well

• Facilitate uniform dispersion and blending in applications where a controlled viscosity is required.
• The compact powder form minimizes storage space while maintaining ease of handling and measurement.
• Its relatively low colour intensity reduces contamination risks and improves the appearance of final products.
• With a hydroxyl value of 27–30 mg KOH/g, PEG 4000 can effectively balance reactivity and stability in formulations.
• Available in convenient packaging suitable for small-scale laboratory research to large-scale industrial production.

Product Use Cases

In pharmaceutical development, Polyethylene Glycol 4000 serves as a critical excipient in tablet formulations, ensuring consistent dissolution profiles and improved bioavailability.
