PEG 1500 is a polyethylene glycol grade with a nominal average molecular weight of approximately 1,500 g/mol. It is generally a waxy solid at room temperature and is valued for its water affinity, binding and lubricating behavior, and ability to soften or adjust the consistency of formulations. Buyers commonly evaluate it for pharmaceutical, personal-care, and industrial applications, but suitability depends on the required grade, formulation, and applicable regulations. At OXIRANCHEM, we help B2B buyers assess PEG 1500 specifications and sourcing requirements before placing an order.

This guide is for product developers, procurement teams, formulators, and manufacturers comparing PEG 1500 with other polyethylene glycol grades. It is intended to support early-stage material selection rather than replace application testing or regulatory review. The information applies broadly, while actual performance and compliance depend on the product specification and intended use. Buyers should confirm all critical requirements with their supplier before approving a material.
PEG 1500 is a polyethylene glycol, a polymer made from repeating ethylene oxide units and terminated by hydroxyl groups. The “1500” designation refers to its approximate average molecular weight, not a guarantee that every molecule has the same chain length. Commercial specifications may define additional characteristics, such as appearance, pH of a defined solution, water content, or a melting range. These values can differ by manufacturer and grade.
PEG 1500 is typically a solid or wax-like material at ordinary room conditions, with a typical melting range reported around 44–48 °C. Treat this range as an orientation rather than a universal acceptance limit, and use the supplier’s current technical specification for purchasing or process control. PEGs are generally water-soluble, while solubility and compatibility in other media depend on the formulation and conditions. Its relatively low volatility and hydrophilic character can be useful in formulations, but they do not by themselves establish suitability for a specific product.
In a formulation, PEG 1500 may contribute lubrication, binding, plasticizing, or consistency modification. The dominant function depends on concentration, other ingredients, processing conditions, and the finished product’s required performance. For example, its solid form can help provide structure in some blends, while its affinity for water can influence moisture behavior. Bench testing is important because interactions with other ingredients may change texture, stability, or release characteristics.
PEG 1500 is one grade within a wider range of polyethylene glycols. Lower-molecular-weight grades are often liquids or more fluid materials, while higher-molecular-weight grades are generally more solid; however, physical form should be confirmed against the specific product specification. PEG grades are not interchangeable solely because they share the same chemical family. Molecular-weight range, purity, physical form, and intended-use requirements all matter.
| Buyer consideration | Why it matters | What to confirm |
|---|---|---|
| Grade and intended use | Different applications may require different quality controls or regulatory documentation. | Whether the offered grade matches the application and destination-market requirements. |
| Molecular-weight designation | It influences physical form and functional behavior. | The supplier’s stated range or test method, where applicable. |
| Physical and chemical limits | These can affect processing and product consistency. | Appearance, melting range, water content, and any other application-critical limits. |
| Documentation and packaging | Traceability and handling needs vary by buyer and market. | Available quality documents, package options, labeling, and storage guidance. |
PEGs are used in pharmaceutical formulations for functions such as binding, lubrication, or as components of bases and carriers. PEG 1500 may be considered when a formulation benefits from a solid, water-affine material with a suitable consistency profile. The correct grade must be selected for the product category and jurisdiction, and the buyer should verify applicable pharmacopeial or regulatory requirements rather than assume compliance from the PEG name alone. Final formulation performance and safety require assessment by the responsible product team.
In personal-care formulations, PEG 1500 may be evaluated as a consistency modifier, binder, or formulation aid. Its role depends on the product format and the behavior of the complete ingredient system. Compatibility, sensory characteristics, stability, and local ingredient rules should all be assessed during development. Buyers should request grade-specific documentation when the material is intended for a regulated or consumer-facing product.

Industrial formulators may investigate PEG 1500 for binding, lubrication, or moisture-related functions in selected processes. It may also be considered as part of a blend where a solid polyethylene glycol is preferred over a liquid grade. The correct choice depends on equipment, processing temperature, contact materials, and the required properties of the finished product. A small-scale trial can identify practical issues before production adoption.
Start by stating what PEG 1500 must do in the product or process. Distinguish between a primary function, such as binding, and secondary effects, such as changing consistency or moisture behavior. This helps suppliers recommend a relevant grade and prevents selection based only on a familiar product name. Include the final-use context when requesting a quotation or technical review.
List the properties that directly affect acceptance, processing, or compliance. These may include molecular-weight designation, appearance, melting behavior, water content, or purity-related limits, depending on your use. Avoid adding unnecessary limits that do not influence product performance, as they can narrow sourcing options. Confirm test methods and acceptance criteria with your quality team and supplier.
Evaluate the material in the actual formulation or a representative process rather than relying on general descriptions. Record mixing behavior, appearance, handling, and relevant finished-product results. When temperature affects processing, use controlled trials; for exploratory work, a 5 °C step between pilot setpoints can help compare behavior without treating the result as a universal processing instruction. Establish final operating conditions through your own validated process.
Confirm whether the material must meet a particular pharmacopeial, cosmetic, food-contact, or industrial requirement. Ask what documentation is available for the offered grade and verify that it covers your destination market and application. Also check packaging, shelf-life information where provided, storage guidance, and lot traceability. These details should be agreed before purchase rather than assumed from a generic product description.
PEG 1500 pricing can vary with grade, order quantity, packaging, origin, freight, and documentation requirements. Minimum order quantities and lead times are supplier- and order-specific, so buyers should request a current quotation rather than rely on a general market estimate. If you are qualifying a new source, ask whether sample quantities or trial orders are available. For repeat supply, share forecast demand and delivery locations so the supplier can assess practical availability.
Choosing PEG 1500 is not only a question of molecular-weight designation; the grade, specification, intended use, and supply conditions must fit together. OXIRANCHEM supports B2B buyers seeking PEG 1500 by discussing application requirements, confirming available product information, and aligning quotation details with purchasing needs. To start an inquiry, share your target application, required specification or grade, estimated quantity, packaging preference, and destination. We can then review the request and provide relevant availability and commercial details for your evaluation.
PEG 1500 is a solid polyethylene glycol grade with potential uses in pharmaceutical, personal-care, and industrial formulations where its binding, lubricating, or consistency-related functions are relevant. Its approximate average molecular weight is 1,500 g/mol, and a typical melting range is about 44–48 °C, but the supplier’s specification should determine purchasing decisions. The practical next step is to define your application and critical limits, request grade-specific documentation, and test the material under representative conditions. Contact OXIRANCHEM with your requirements to discuss PEG 1500 sourcing and available product details.
