Polyethylene glycol 10000, often written PEG 10000 or PEG 10,000, is a high-molecular-weight, water-soluble polymer used in industrial formulations and selected personal-care, laboratory, and other applications. The number refers to a nominal average molecular weight of approximately 10,000 g/mol; it is not a guarantee that every polymer chain has exactly that molecular weight. Buyers typically evaluate it for its solid form, compatibility with water-based systems, and function as a binder, lubricant, thickener, or processing aid. The right grade depends on the application, required specifications, and any regulatory or quality requirements.

This guide is intended for procurement teams, formulators, product developers, and distributors assessing PEG 10000 for a new or existing product. It can also help buyers compare supplier offers that use different specification formats or describe the material in different ways. Because the same chemical name can cover products with differing quality controls, the grade and documentation matter as much as the name. We recommend treating this guide as an introduction and confirming application-critical details with your supplier.
Polyethylene glycol is a family of polymers formed from repeating ethylene oxide units and commonly identified by an approximate average molecular weight. PEG 10000 is a higher-molecular-weight member of this family and is generally handled as a solid rather than as a low-viscosity liquid. It is also known in some contexts as macrogol 10000, although naming conventions and grade requirements depend on the market and application. A product’s intended use should never be inferred from the name alone.
PEG grades can differ in molecular-weight distribution, moisture, appearance, and other measured properties. These differences may affect dissolution, handling, processing behavior, or finished-product performance. Therefore, a technical data sheet and, where appropriate, a batch-specific certificate of analysis should be used to assess an offered product. If a particular test method or limit is essential, include it in the inquiry rather than relying on a general product description.
PEG 10000 is commonly described as a white or off-white solid, such as flakes, powder, or another solid form depending on how it is manufactured and supplied. It is hydrophilic and can dissolve in water, though dissolution rate depends on factors such as particle form, temperature, concentration, and mixing. A melting range commonly cited for PEG 10000 is approximately 60–63°C, but the measured result can vary with grade and test method. These reference values should be confirmed against the specific product specification before use in process design.
| Property to review | What buyers should check |
|---|---|
| Average molecular weight | Whether the specification identifies a nominal value, range, or measurement method |
| Appearance and form | Whether the supplied flakes, powder, or other form suits handling and feeding equipment |
| Melting behavior | The supplier’s stated range and the method used to determine it |
| Water compatibility | Any application-specific dissolution or solution-preparation requirements |
| Quality documentation | Available specification, batch documentation, and any required regulatory statements |
The nominal molecular weight of 10,000 g/mol is useful for identifying the grade, but it does not replace a complete specification. For a formulation, users may also need limits for moisture, pH of a prepared solution, or other quality parameters. Not every supplier tests or reports the same parameters, so compare like with like. Where a property is critical, request the method, acceptance limit, and representative batch documentation.
In industrial applications, PEG 10000 may be considered as a binder, lubricant, release aid, or processing additive, depending on the material system and process. Its water affinity can be useful when a formulation requires a water-compatible polymer, while its solid form can support controlled addition in some manufacturing workflows. The final effect depends on concentration, other ingredients, process temperature, and mixing conditions. Pilot-scale testing is prudent before changing a production formula.
PEG materials are used in some personal-care and specialty formulations, but suitability depends on the finished product, grade, and applicable regulations. PEG 10000’s higher molecular weight may make it a different functional choice from lower-molecular-weight PEG grades. Buyers should confirm the intended ingredient status, impurity requirements, and documentation for the target market. A general industrial grade should not be assumed suitable for cosmetic, pharmaceutical, food-contact, or medical use.

Research and development teams may evaluate PEG 10000 when they need a water-compatible polymer for formulation or process studies. Its higher molecular weight can influence viscosity and handling compared with lower-molecular-weight grades, particularly as concentration changes. This is a reason to test the actual material under representative conditions rather than relying only on a generic property description. Record the grade, batch, preparation method, and test conditions so that results can be reproduced.
Selection should be based on the complete use case, not just a match on “PEG 10000.” For example, a buyer whose process depends on a specific dissolution profile should request information relevant to that profile and test samples under defined conditions. A buyer with regulated-market requirements should verify grade suitability and documentation before purchase. Clear specifications reduce the risk of comparing offers that are not technically equivalent.
The price of PEG 10000 can depend on the grade, order volume, packaging, destination, and current supply conditions. Minimum order quantities and lead times are likewise supplier- and shipment-specific, so they should be confirmed when requesting a quotation rather than assumed from a product listing. For a fair comparison, provide the same target specification and delivery requirements to each supplier. Also ask whether the quotation covers the requested packaging and supporting documents.
For development work, ask whether a sample or smaller evaluation quantity is available and what conditions apply. For recurring production, discuss forecast volumes and planned order frequency so the supplier can assess an appropriate supply arrangement. No quotation should be treated as confirmation of technical suitability; product approval remains dependent on your application testing and quality review.
At OXIRANCHEM, we support B2B buyers evaluating polyethylene glycol 10000 by discussing application requirements, grade information, documentation needs, packaging, and shipment details. We encourage customers to share their target specification and intended use so we can review the inquiry against available product information. Where an application has strict performance or compliance criteria, buyers should confirm these requirements before placing a production order. This helps both sides align on the material and the commercial scope.
Polyethylene glycol 10000 is a high-molecular-weight, water-compatible polymer that may serve as a binder, lubricant, processing aid, or formulation component in suitable applications. Its nominal average molecular weight is approximately 10,000 g/mol, while reported physical properties such as melting behavior should be checked against the offered grade and test method. It is not automatically suitable for every formulation or regulated use. The best next step is to define your performance and documentation requirements, review the supplier’s specification, and test the material under representative process conditions.
For a quotation or product discussion, contact OXIRANCHEM with your target grade, application, required documents, estimated order quantity, packaging preference, and delivery destination. With those details, we can help you assess the appropriate supply option and clarify the information needed for your evaluation.
