Peg - 4000

Description :

PEG 4000 Supplier and Exporter for the UK

Chemical Bull supports PEG 4000 sourcing for UK buyers, serving industrial formulators, personal care manufacturers and qualified excipient buyers. Share your required grade, specification and order quantity to request a supply quotation. Our role is to coordinate the offered material and commercial details against your purchasing requirements.

What Is PEG 4000?

PEG 4000 is a higher-molecular-weight polyethylene glycol grade, generally supplied in solid form. Its grade number indicates an approximate average molecular mass within a specified distribution.

CAS number: 25322-68-3. Confirm this identity against the documentation for the supplied material.

PEG 4000 Uses and Industrial Applications

Industrial binding and processing

The polymer can function as a binder, lubricant or processing aid in selected systems. Physical form and melting behaviour influence production handling.

Personal care formulation

Qualified grades may adjust consistency or provide a carrier function. Compatibility and sensory effects should be checked in the complete product.

Pharmaceutical excipient sourcing

Compendial grades can be assessed for validated excipient applications. Establish the required monograph, impurity controls and approved specification.

Choosing the Right PEG 4000 Grade

For bulk PEG 4000 procurement, specify average molecular mass range, hydroxyl value, melting range, water and relevant impurity tests. Where the manufacturer uses a trade grade or a particular test method, include that reference in your enquiry. The offered specification should match the material you intend to approve for production.

Specify the PEG grade and the quality standard required by the application. The average molecular mass range, hydroxyl value and impurity controls are more informative than the grade number alone. Industrial, cosmetic and compendial materials need different qualification. For pharmaceutical use, identify the required monograph and supporting documentation before commercial discussion. Physical form and melting or dissolution behaviour should also suit the equipment used to charge and mix the formulation.

Production Trials and Quality Checks

Assess the ingredient at the actual concentration and processing temperature. Compare clarity, viscosity and stability with the existing formulation. Where the product is used as an excipient, include the required quality qualification and relevant impurity testing rather than approving it solely on physical performance.

For repeat supply, agree the acceptance limits and document requirements before the first commercial order. Review the batch Certificate of Analysis against that specification, and keep a retained sample where your quality procedure requires it. If a test method differs between sources, resolve that difference before treating the results as equivalent.

Storage and Handling

Keep storage and transfer conditions consistent with the SDS and the technical data for the supplied form. Prevent contamination and account for any water uptake that could alter the specification. For solid grades, establish a controlled dissolution or melting procedure. For liquid grades, confirm transfer arrangements and container cleanliness.

PEG 4000 MSDS, SDS and Technical Documentation

Request the current PEG 4000 MSDS or Safety Data Sheet (SDS) for the exact offered grade. The document covers hazard identification, handling, storage, exposure controls and transport information. Ask separately for the product specification, Technical Data Sheet where available, and a batch Certificate of Analysis. An SDS supports safe-use assessment; it does not replace a quality specification or demonstrate finished-product approval.

PEG 4000 Price and Bulk Supply for UK Buyers

The PEG 4000 price for UK delivery depends on the grade, quantity, packaging, source and agreed delivery terms. Include your delivery postcode, required date and purchasing frequency when requesting a quotation. State whether the destination is in Great Britain or Northern Ireland so the relevant supply arrangements can be reviewed. Availability, freight and any import responsibilities should be confirmed in the quotation before an order is placed.

Frequently Asked Questions

1. What is PEG 4000?

PEG 4000 is a higher-molecular-weight polyethylene glycol grade, generally supplied in solid form. The CAS number is 25322-68-3.

2. What is PEG 4000 used for?

Applications include industrial binding and processing, personal care formulation, pharmaceutical excipient sourcing. The required grade and finished-product suitability depend on the actual formulation or process.

3. Can PEG 4000 be handled like liquid PEG 400?

No. The higher molecular mass changes physical form and processing behaviour. Dissolution, melting and formulation effects require separate assessment.

4. How can I request a bulk PEG 4000 price for the UK?

Send the product name, approved specification, required quantity, packaging preference and UK delivery postcode. Include your target date and documentation requirements for a relevant quotation.

5. Can I request a PEG 4000 MSDS?

Yes. Ask for the current SDS/MSDS for the offered grade, together with the product specification and available COA or TDS. Review the documents before approving the material.
