PEG - 4000 (Polyethylene Glycol 4000)

PEG-4000 (Polyethylene Glycol 4000) is a high molecular weight polymer of ethylene glycol, with an average molecular weight of approximately 4000 g/mol. It is typically a white, waxy solid or a viscous paste at room temperature, depending on its exact formulation. PEG-4000 is highly soluble in water and alcohol and is known for its smooth texture and versatility in various applications.
In the pharmaceutical industry, PEG-4000 is used as a base for ointment formulations, tablet binders, and emulsifying agents. It helps improve the consistency, stability, and controlled release of active ingredients in drug formulations. It is also used as a lubricant in suppositories and other topical treatments, enhancing their smoothness and ease of application. In cosmetics, PEG-4000 is utilized in moisturizers, lotions, and shampoos to condition the skin, improve spreadability, and enhance the texture of products. Additionally, it is employed in industrial applications such as lubricants, coatings, and paints, where it helps modify viscosity and improve flow properties.
