Polyethylene glycol 10000 (PEG 10000) is a high-molecular-weight, water-soluble polyethylene glycol supplied as a solid. Buyers commonly evaluate it for formulation, binding, lubrication, release, and other processing functions, but the right choice depends on the application and the grade’s documented specifications. Its nominal molecular weight is 10,000 g/mol; this describes an average for a polymer distribution, not an exact molecular size for every molecule. Before purchasing, compare the supplier’s current technical data sheet and certificate of analysis with your process requirements.

This guide is intended for B2B buyers, formulators, product developers, and procurement teams assessing PEG 10000 for industrial or specialty applications. It can help you prepare a specification request and compare supplier offers on a like-for-like basis. It is not a substitute for application testing, regulatory review, or the supplier’s product documentation. For regulated uses, confirm that the particular grade and its documentation meet the requirements of your product and market.
Polyethylene glycol is a family of polymers formed from repeating ethylene oxide units. The number in “PEG 10000” refers to an approximate average molecular weight, usually expressed in grams per mole. Because PEG is polydisperse, individual polymer chains vary in length, and a nominal grade should not be interpreted as a single, uniform molecular structure.
At this molecular weight, PEG 10000 is generally supplied as a solid rather than a low-viscosity liquid. Depending on grade and supplier, its appearance may be described as flakes, granules, powder, or a waxy solid. A melting range of approximately 60–63 °C is often reported as a general reference, but the actual result and acceptance limits should be confirmed against the supplier’s current specification.
PEG 10000 is hydrophilic and soluble in water, which can make it useful in aqueous formulations and processing systems. Its handling and performance depend on factors such as temperature, concentration, formulation ingredients, and particle form. Do not assume that results from one grade or supplier will transfer directly to another without checking the documentation and testing the intended formulation.
| Property or document | What buyers should confirm | Why it matters |
|---|---|---|
| Molecular weight designation | Nominal value and the supplier’s measurement or reporting basis | Supports comparison of grades and expected functional behavior |
| Appearance and physical form | Specified form, color description, and any visible-particle criteria | Affects conveying, feeding, dissolving, and storage practices |
| Melting or softening range | Test method, reported range, and batch acceptance limits | Helps assess processing and temperature-handling requirements |
| Moisture and pH | Limits and, for pH, the sample concentration and test method | Can affect storage, formulation consistency, and process control |
| Quality documentation | Current technical data sheet, SDS, and batch-specific COA availability | Provides a basis for technical review and incoming inspection |
Specifications are not universal across all PEG 10000 products. For example, a reported melting range is meaningful only when you know the relevant method and the supplier’s limits. Request a current certificate of analysis (COA) for the offered batch where available, and make sure the values and test methods correspond to your purchasing specification.
Depending on grade and formulation compatibility, PEG 10000 may be considered as a binder, lubricant, carrier, or processing aid. Its solid form can also be relevant where a formulation requires a higher-molecular-weight PEG rather than a liquid grade. The appropriate role should be established through formulation work, since concentration, processing conditions, and interactions with other ingredients can change performance.
In industrial processes, buyers may evaluate PEG 10000 for functions such as lubrication, release, or binding. Suitability depends on the substrate, operating temperature, desired product properties, and downstream handling. For pharmaceutical, personal-care, food-related, or other regulated applications, do not infer approval from the generic PEG name: ask for grade-specific documentation and verify applicable requirements for your intended market.
With competitive price and timely delivery, Xipuao sincerely hope to be your supplier and partner.
Supplier offerings may differ by physical form, purity controls, and intended-use documentation. A powder or granule may suit a different feeding or dissolution process than flakes, even when both are identified as PEG 10000. Compare the exact commercial grade and its documents rather than relying only on the molecular-weight label.
For technical comparisons, distinguish required limits from informational values. If a property is critical to your process, state the test method and acceptance range in the inquiry or purchase specification. This reduces the risk of comparing supplier quotations that use different measurement bases.
PEG 10000 pricing can depend on grade, order volume, packaging, destination, and current supply conditions. Minimum order quantities and lead times are supplier- and order-specific, so there is no reliable universal figure to apply without a quotation. For an accurate offer, provide the target grade or specification, required quantity, destination, packaging preference, and requested delivery schedule.
When comparing quotations, include more than the unit price. Check whether the offer identifies the exact product grade, batch documentation, packaging details, and any special handling or shipping requirements. If you are qualifying a new material, ask whether a sample or trial quantity is available and clarify whether it represents the same grade you would purchase in bulk.
At Xipuao, we support B2B buyers evaluating polyethylene glycol products by discussing the intended application, required specifications, and purchasing details. We can help clarify the information needed for a product inquiry, including target grade, physical form, quantity, destination, and documentation expectations. Availability, commercial terms, and product-specific documents should be confirmed for each request rather than assumed from a general product description.
PEG 10000 is a solid, water-soluble polymer with a nominal molecular weight of 10,000 g/mol, and it may suit applications requiring binding, lubrication, release, or related formulation functions. The best grade is the one whose verified specifications and documentation match your process—not simply the one carrying the right molecular-weight label. Confirm the physical form, test methods, acceptance limits, and intended-use suitability before placing an order.
As a next step, prepare your application details, target quantity, required specification, and delivery destination, then request the relevant technical documents and a quotation. Contact Xipuao to discuss your PEG 10000 requirements and determine what product information is available for your evaluation.
